Household gas appliances, including boilers and gas ovens, are often used daily but can cause fires and carbon monoxide poisoning if they become faulty.

<p>Household gas appliances, including&nbsp;<a rel="follow" href="https://www.boxt.co.uk/boilers">boilers</a>&nbsp;and gas ovens, are often used daily but can cause fires and carbon monoxide poisoning if they become faulty.</p>
<p>To raise awareness for Gas Safety Week, BOXT surveyed 2,000 people to discover how gas safe the UK public are. We have put together a guide for homeowners on how to keep their homes safe by preventing and recognising the signs of gas emergencies.&nbsp;</p>
<h2><strong>Smoke alarms</strong></h2>
<p><img alt="undefined" src="https://boxt-bcms.imgix.net/5VITyxZIRpKhtJvz7X4L?auto=format"></p>
<p>Smoke detectors are essential for preventing casualties in fires. However, a smoke alarm wasn't present for&nbsp;<a rel="follow" href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/923072/detailed-analysis-fires-attended-fire-rescue-england-1920-hosb2820.pdf">24% of all dwelling fires in 2019/20, and a smoke alarm either didn't operate or raise the alarm for 31%</a>.</p>
<p>To ensure your smoke alarms are working correctly, check them all once a week using the test button and change them every ten years. Depending on the manufacturer and model of the smoke alarm, change the batteries annually. However, you should replace the batteries immediately if the low battery warning alerts.</p>
<p>In the BOXT survey, just 11% of respondents tested their smoke and carbon monoxide alarms weekly, while 25.9% tested them monthly.</p>
<p>The placement of smoke alarms influences their effectiveness. Install the alarms in any room where there's a fire risk, on every level of the house. To accommodate rising smoke, install the alarms on the ceiling or high on the wall.</p>
<p>But don't place the alarms in bathrooms or kitchens; opt for a heat alarm in the kitchen instead, as the steam that emerges in these rooms can damage smoke alarms. Keep them away from doors, fans, and windows to stop draughts from blowing any smoke away from the detectors.&nbsp;</p>
<p>When choosing smoke alarms, opting for models with a ten year or long-lasting sealed battery reduces the frequency of battery changes. Ensure the smoke alarms have the current British Standards or European (CE) safety mark. Interconnect all smoke alarms, if they're compatible, so they all sound if one detects smoke to warn everybody inside the property.</p>
<h2>Carbon monoxide alarms&nbsp;</h2>
<p><img alt="undefined" src="https://boxt-bcms.imgix.net/GZ1WiALfR5eMGKbUKWAs?auto=format"></p>
<p>Carbon monoxide is known as the silent killer because you can't see, smell, or taste the highly poisonous fumes.&nbsp;<a rel="follow" href="https://www.nhs.uk/conditions/carbon-monoxide-poisoning/">According to the NHS</a>, 60 people die from carbon monoxide poisoning yearly across England and Wales. But a carbon monoxide detector can alert you to a leak so you can respond accordingly and escape the potentially life-threatening situation.&nbsp;</p>
<p>Yet, in the BOXT survey, 26.5% of Brits confessed to not having a carbon monoxide alarm installed in their current home.&nbsp;</p>
<p>If your home has a fuel-burning boiler, fire or stove, you should fit a carbon monoxide detector in every room where the fuel burns. However, homes that entirely run on electricity aren't required to install this detector.&nbsp;</p>
<p>In any room containing a fuel-burning appliance, fit alarms certified to British Standard EN50291 and have the British or European approval mark. Landlords are&nbsp;<a rel="follow" href="https://www.gov.uk/government/publications/smoke-and-carbon-monoxide-alarms-explanatory-booklet-for-landlords/the-smoke-and-carbon-monoxide-alarm-england-regulations-2015-qa-booklet-for-the-private-rented-sector-landlords-and-tenants">legally required to fit a carbon monoxide alarm</a>&nbsp;in any room in a property utilised as living accommodation where solid fuels are combusted.</p>
<p>To ensure the alarms warn you against a carbon monoxide leak, keep the detectors in working condition by testing them a minimum of once a week. Also, if the batteries are replaceable, change them at least every six months.&nbsp;</p>
<p>In the survey, only a quarter of respondents claimed to check the carbon monoxide detectors monthly. Shockingly, 12.3% confessed to never checking the alarms, and another 7.8% didn't even know where their smoke and carbon monoxide alarms were.</p>
<p>What are the signs of carbon monoxide poisoning?&nbsp;</p>
<p>As well as installing a carbon monoxide alarm, it's also critical that you can recognise the symptoms of poisoning, which are often confused for the flu, food poisoning, and tiredness. However, unlike the flu, carbon monoxide poisoning doesn't cause a high temperature.</p>
<p>Carbon monoxide exposure can lead to symptoms including:&nbsp;</p>
<ul style="list-style-type: disc;">
<li>Tension headaches</li>
<li>Dizziness</li>
<li>Nausea</li>
<li>Breathlessness</li>
<li>Tiredness and confusion</li>
<li>Stomach pain</li>
</ul>
<p><img alt="undefined" src="https://boxt-bcms.imgix.net/qTP9kHaNTvKdqg6GLEPi?auto=format"></p>
<p>The BOXT study revealed that only 25% of respondents would recognise the main symptoms. Another 23% said they would recognise the signs that an appliance isn't working correctly.&nbsp;</p>
<p>It's also important to look out for the signs of carbon monoxide poisoning around your home, such as:&nbsp;</p>
<ul style="list-style-type: disc;">
<li>Soft yellow flames coming from gas appliances instead of blue flames.</li>
<li>Pilot lights that frequently blow out.</li>
<li>Sooty stains or discolouration on or around gas appliances.</li>
<li>Increased condensation inside windows.</li>
</ul>
<p>Worryingly, the survey found that 12.7% of respondents would have no idea what to do in the instance of a carbon monoxide leak. &nbsp;</p>
<h2><br>Gas appliances&nbsp;</h2>
<p><img alt="undefined" src="https://boxt-bcms.imgix.net/NSUeLKVQvaWfeuOhK61g?auto=format"></p>
<p>A qualified engineer should check all the gas appliances in your property and conduct a&nbsp;<a rel="follow" href="https://www.boxt.co.uk/boilers/boiler-service">boiler service</a>&nbsp;annually to ensure they operate safely and effectively. These appliances could cause a dangerous gas leak, fires, explosions, and carbon monoxide poisoning if defective.</p>
<p>While just over half of those surveyed followed the advised yearly checks, 14.1% said they never checked their gas appliances.&nbsp;</p>
<p>Of those who hadn't had their gas appliances safety checked within the past year, 15.1% blamed COVID, as they no longer wanted people in their homes. Another 13.6% didn't know they needed to conduct these safety checks, and another 11.1% didn't think it was necessary. 8.8% of respondents couldn&rsquo;t afford a yearly gas safety check.</p>
<p><img alt="undefined" src="https://boxt-bcms.imgix.net/SFjWZEGS7OhieNzeWhX1?auto=format"></p>
<p>Additional ways to maintain the quality of gas appliances include only using them for their intended purpose, e.g. not using an oven to heat a room and not blocking vents or chimneys.</p>
<p>Unlike carbon monoxide, gas leaks often create a noticeable scent. But it can also cause physical symptoms like dizziness, nausea, and headaches.&nbsp;</p>
<h2><br>What to do if you suspect a gas or carbon monoxide leak</h2>
<p>If you suspect a gas or carbon monoxide leak in your home, turn the gas off, open all the windows, and leave the property immediately to get fresh air. If anyone is showing symptoms of carbon monoxide poisoning, get them outside and call 999 for an ambulance.</p>
<p>Call the 24 hour Gas Emergency Number on 0800 111 999 and don't return to your house until the source of the leak has been found and fixed by a gas safe registered professional.&nbsp;</p>
<p>Don't smoke, light a match, or use any form of naked flame. Don't turn any electrical switches on or off. Also, don't use doorbells, mobile phones, or any other electrical switches that could trigger a spark.&nbsp;</p>
<blockquote>
<p><br>Andy Kerr, co-founder of BOXT says: "Carbon monoxide leaks are easy to miss if you don't have a working detector, as you can't see, smell, or taste the poisonous fumes.</p>
<p>"Every second counts after being exposed to carbon monoxide. So, you must be able to recognise the signs of carbon monoxide poisoning and know how to respond in the event of a leak.</p>
<p>"While gas and carbon monoxide poisonings are extremely serious, you can minimise the risk by conducting regular maintenance of gas appliances, smoke alarms, and carbon monoxide detectors. This safety takes little time and can save your life.</p>
<p>&nbsp;&ldquo;Ensure you get your gas appliances checked by a Gas Safe registered engineer and check their Gas Safe ID card for reassurance of their qualifications.&rdquo;</p>

How to keep your home Gas Safe

Being gas safe is incredibly important and involves ensuring that all of the gas appliances in your home, such as boilers, cookers and heaters, are properly installed and maintained.

<p>Being gas safe is incredibly important and involves ensuring that all of the gas appliances in your home, such as boilers, cookers and heaters, are properly installed and maintained. By failing to meet gas safety regulations, you are risking events such as gas explosions and leaks, fires, monoxide poisoning and even prosecution.</p>
<ol>
<li><strong>Get an annual gas safety check -</strong>&nbsp;it&rsquo;s really important to have a Gas Safe registered engineer check your gas appliances every year. By having these checks completed annually, you can be assured that all of your gas appliances are working as they should be, or you can be notified of any potential issues.</li>
<li><strong>Look out for signs that your boiler isn&rsquo;t working correctly -&nbsp;</strong>potential signs of a fault in your boiler can include visible leaks, strange smells and noises, a flame that isn&rsquo;t blue, fluctuations in water temperature and high energy bills.</li>
<li><strong>Purchase a carbon monoxide alarm -&nbsp;</strong>carbon monoxide detectors essentially do the same job as a fire alarm, but instead, they work to detect carbon monoxide rather than smoke. Due to carbon monoxide being odourless, colourless and tasteless, an alarm can potentially save your life, as the gas is otherwise hard to detect. In the UK, between 40 and 50 people die and approximately 200 people are hospitalised every year due to carbon monoxide poisoning.</li>
<li><strong>Know the symptoms of carbon monoxide poisoning -&nbsp;</strong>you must know the symptoms of carbon monoxide poisoning and can identify these in a person, as it can be deadly. As previously mentioned, symptoms include headaches, dizziness, nausea, fatigue and irregular breathing. If any of these symptoms are identified either within yourself or another household member, seek help from a medical professional immediately.</li>
<li><strong>Ensure there is adequate ventilation -&nbsp;</strong>for your gas appliances to burn correctly, they may require specific ventilation or air vents. This means ensuring that no air vents or chimneys in your home are blocked or obstructed.&nbsp;</li>
</ol>

Explore what the ECO4 scheme means for you, the eligibility criteria, how much you can apply for, the child benefit income threshold and more in this guide.

<p>The UK Government launched its fourth instalment of the Energy Company Obligation (ECO4) in April 2022, a scheme which will run until March 31st 2026 and provide funding to support the country&rsquo;s efforts to work towards a greener future.</p>
<p>The scheme aims to increase energy efficiency measures and heating in vulnerable households. It is funded by energy companies, who decide which projects they&rsquo;ll support, the level of funding available, and the scheme coordinator and installers they&rsquo;ll work with.</p>
<p>In this guide, we explore the ECO4 scheme in more detail, explaining its benefits, the eligibility criteria and how you can apply for funding.</p>
<h2>What is the ECO4 scheme?</h2>
<p>Initially launched in 2013, the Energy Company Obligation (ECO) aims to make homes warmer and reduce carbon emissions while making energy suppliers accountable for supporting vulnerable and low-income households.</p>
<p>Since its introduction, ECO has installed around 3.5 million insulation and heating measures in 2.4 million homes. Highlighting its popularity and the critical work done to ensure people can access the energy-efficient upgrades that their homes need.</p>
<p>The scheme aims to deliver a more complete upgrade of homes, taking a whole-home approach that improves multiple aspects of a home's efficiency levels and reduces energy bills. This is to reach new minimum energy efficiency requirements - increasing homes from D and E bandings to at least a C, and F and G rated homes to band D.</p>
<p>As well as helping people pay for crucial work to energy inefficient properties, the scheme also contributes to the Government's commitment to reducing the nation's carbon emissions and net-zero targets.</p>
<h3>What is ECO4 Flex?</h3>
<p>ECO4 flex, or local authority flexible energy, is a referral mechanism that enables councils to widen the reliability criteria for the ECO4 scheme and tailor it to their specific area.</p>
<p>Under ECO4 Flex, a participating local authority can refer private tenure households that it considers to be living in fuel poverty or on a low income and vulnerable to the point of living in a cold home. ECO4 Flex is optional but allows suppliers to deliver up to 50% of their ECO obligation.</p>
<p>If a local authority wants to provide ECO4 funding through the Flex scheme, it must publish a statement of intent document outlining that it intends to participate in the scheme and follow the relevant rules to help households that don't claim benefits to access funding.</p>
<p>Local authorities are responsible for determining eligible households and may delegate this power to other councils.</p>
<h3>How much funding can you apply for on the ECO4 scheme?</h3>
<p>With ECO4, you can access up to &pound;10,000 in funding to increase your home's energy efficiency rating. And you can use this money to buy a whole range of products and measures, from insulation to solar panels, an air source heat pump, or a new boiler.</p>
<h2>How can you apply for an ECO4 grant?</h2>
<p>To apply for the ECO4 scheme, contact your local council to find out if they're participating or contact energy suppliers directly. You can find information on the energy suppliers taking part, and their contact details, <a href="https://www.ofgem.gov.uk/eco-supplier-contact-details" rel="nofollow noopener" target="_blank">on the Ofgem website</a>.&nbsp;</p>
<p>You can get support from any provider, not just your energy supplier, provided you meet the eligibility criteria.</p>
<h3>What are the eligibility criteria for the ECO4 scheme?</h3>
<p>To benefit from the ECO4 scheme, you must own your home or have permission from your landlord, social housing provider or management company. It's important to remember that ECO4 is not a grant and that the participating energy companies may provide different levels and types of support. Because of this, we recommend you shop around for the deal most suited to you and your home's needs.</p>
<p>Eligible households must have an energy performance certificate (EPC) rating of D-G and receive one of the benefits below.</p>
<p>You'll be eligible for help under the ECO4 scheme if you live in private domestic premises and are a Help to Heat Group (HTHG) member. To be a&nbsp;member of the HTHG, you must receive one of the benefits below and satisfy the relevant income requirements.</p>
<h4>What benefits qualify for the ECO4 scheme?</h4>
<p>The list of benefits qualifying for the ECO4 scheme has changed, with some qualifying during the ECO3 scheme no longer being included.</p>
<p>The following benefits do qualify for ECO4 funding:</p>
<ul>
<li>Child tax credits (CTC)</li>
<li>Child benefits - depending on income threshold</li>
<li>Jobseekers Allowance (JSA)</li>
<li>Employment and Support Allowance (ESA)</li>

<h3>In-fill houses and flats</h3>
<p>Some households may not meet the criteria for fuel poverty or vulnerability but are on the same street or building block as households that meet the requirements for ECO4 help, and these properties may also be eligible for support. These measures are known as in-fill.</p>
<p>Separate rules apply for in-fill flats and houses. For every flat that meets the ECO4 eligibility criteria, one in-fill flat can be treated in the same block or building. In-fill flats can receive solid wall insulation, district heating system connection or cavity wall insulation.</p>
<p>Meanwhile, for every three houses treated by the ECO4, one in-fill house on the same street can be treated. These properties will be eligible for solid wall insulation or district heating system connection.</p>

<h2>How to choose the right boiler brand and model for your home</h2>
<p>Once you know which brand you want, there are other considerations to help choose the right model. We've broken them down for you so you can be more confident in making the right choice for you and your home.</p>
<h3>Consider your home's heating needs and preferences</h3>
<p>We recommend assessing the size of your home and its heating demands. Larger homes or those with multiple bathrooms may need a more powerful boiler.</p>
<p>The best boilers for large houses tend to be standard or system boilers, as they're able to provide enough hot water for all of your bathrooms simultaneously as well as having enough power to heat your radiators, and underfloor heating systems.</p>

Want more information on what types of boilers are best for large homes? Check out our comprehensive blog. We've rounded up a list of the most efficient boilers for homes with five or more bedrooms.

<h3>Consult with a professional heating engineer</h3>
<p>Heating engineers have in-depth knowledge of various boiler brands and models, so you should seek their advice before making your final decision. They can assess your specific heating needs, the size of your property, and your hot water demands to provide tailored recommendations that align with your requirements.</p>
<p>When you buy a boiler through BOXT, we'll provide recommendations of the most suitable boiler makes and models in minutes.</p>
<p>Once you've made your choice, it's essential to have your boiler installed by an experienced Gas Safe registered engineer. Our engineers can deliver and install your new boiler in as little as 24 hours.</p>
<h3>Weigh up short and long-term costs</h3>
<p>By carefully weighing both the short and long-term costs of different boiler brands, you can make an informed decision that sits within your budget both when you buy your new boiler and when you're running it day-to-day.</p>
<p>Short-term costs include the initial purchase price and installation expenses. While we, as buyers, might have a tendency to focus solely on these upfront costs, a more expensive boiler with higher energy efficiency can result in lower long-term operational costs.</p>
<p>Long-term costs should account for maintenance and potential repair costs. While high-quality boilers may have higher upfront costs, they often come with better build quality and reliability, reducing the likelihood of breakdowns. Plus, in most cases they offer a longer warranty too.</p>
<h3>Find energy efficiency ratings</h3>
<p>Energy-efficient boilers consume less fuel, leading to lower energy bills and more money in your pocket. Understanding the energy efficiency ratings of different models helps you choose a boiler that can provide significant long-term cost savings on your energy expenses.</p>
<h3>Check for warranty</h3>
<p>Consider the warranty offered by each brand. A longer warranty period can provide peace of mind and act as a testament to the brand's durability.</p>
<p>We'd also recommend checking the availability of customer support. Knowing that reliable customer support is available can be crucial if you encounter issues with your boiler. A responsive and accessible customer support team can help address concerns, provide guidance, and facilitate repairs.</p>
<p>A brand that stands behind its products with strong warranties and excellent customer support is likely to have a positive reputation in the market. Researching customer reviews can provide insights into how satisfied users are with a brand's support services.</p>

<h2>Worcester Greenstar 4000 review</h2>
<p>With around 7 million boilers installed nationwide, Worcester Bosch is one of the most recognised and respected companies in the sector. But how does the Greenstar 4000 boiler stack up in key categories like reliability, cost and efficiency? Let's find out.</p>
<h3>Worcester Bosch Greenstar 4000: Reliability</h3>
<p>Worcester Bosch has built its reputation on producing highly reliable boilers, and the manufacturer-backed 10-year guarantee is a sign of the Greenstar 4000's quality.</p>
<p>If your boiler does require servicing or maintenance, the removable side panels mean all key components can be accessed quickly and efficiently, so if your engineer charges by the hour, this can save valuable time and money.</p>
<p>For further proof that Worcester Bosch is a reliable boiler manufacturer, the company is rated excellent on <a href="https://uk.trustpilot.com/review/www.worcester-bosch.co.uk" rel="follow noopener" target="_blank">Trustpilot</a>, with an average rating of 4.6 out of 5 from over 40,000 reviews.</p>
<p>The annual boiler report from Which? has also revealed that Worcester Bosch is the most reliable boiler brand on the market based on customer satisfaction, product quality and after-care. As a result, the boiler company has been endorsed as one of Which&rsquo;s Best Buy Brands for the last 14 years.&nbsp;</p>
<p><strong>Reliability score: 5/5</strong></p>
<h3>Worcester Bosch Greenstar 4000: Efficiency</h3>
<p>The Greenstar 4000 has received an ErP rating of A. So, if you want to upgrade your old boiler, a Greenstar 4000 could save you money on your heating bills and reduce gas consumption.</p>
<p>More specifically, the boiler's energy efficiency is 94%, so just 6% of the energy used to heat the water is lost during the heating process. If you equate this to money, that means for every &pound;1 you spend on heating your home, just 6p is lost.</p>
<p>Another feature that helps to save energy and water is the Quick Tap addition. Turn your hot tap on and off to start the boiler up, leave it for 30 seconds before turning it back on, and you'll have hot water without running the tap and wasting water. This may seem like a small detail, but it can make a big difference when people all around the country are doing the same thing.</p>
<p>The boiler's power can be reduced to 10% of its output to maximise efficiency further, through a process called modulating. So, if you have the 30kW boiler, it can automatically reduce the power to 3kW. Modulating the performance in this way means that when there is little or no demand for the boiler, e.g. during the summer months, you won't be wasting electricity or money on unnecessarily high energy bills.</p>
<p>Read more about how efficiency ratings are calculated in '<a href="https://www.boxt.co.uk/boilers/guides/boiler-efficiency" rel="follow">Boiler efficiency: a complete guide</a>'.</p>
<p><strong>Efficiency score: 5/5</strong></p>
<h3>Worcester Bosch Greenstar 4000: Performance</h3>
<p>To maximise performance, the Greenstar 4000 has an optional extra intelligent filling valve that adds boiler pressure to keep your system at the optimal amount.</p>
<p>The boiler's intelligent filling system doesn't stop there, as it will notify you if the boiler is losing too much pressure so you can call a Gas Safe engineer to come and inspect the problem before it gets worse.</p>
<p>One of the things that makes the Greenstar 4000 such a good choice for smaller homes is its flow rate. The 25kW option provides 10.5L per minute, making it an excellent choice for those with one bathroom and up to 10 radiators.</p>
<p>If your home has higher hot water demands, i.e. more than one bathroom, the 30kW option can provide 12.3L per minute and comfortably service your home.</p>
<p>Is a frozen condensate pipe an all too common occurrence with your current boiler? Well,&nbsp;<br>Worcester Bosch has thought of this, too. The Greenstar 4000 is specially designed to avoid freezes when the temperature drops, so you and your home can remain toasty and warm whatever the weather.</p>
<p>If your current boiler is struggling in the cold weather, discover <a href="https://www.boxt.co.uk/boilers/guides/how-to-fix-a-frozen-boiler-condensate-pipe" rel="follow">how to fix a frozen boiler condensate pipe</a> in our guide.</p>
<p>Another key performance benefit to the Greenstar 4000 is that it's less noisy than its predecessor, the Greenstar i. The combi version of the 4000 operates at just 45 decibels - about the <a href="https://soundear.com/decibel-scale/" rel="follow noopener" target="_blank">same loudness as a library</a>, and they're known for being very quiet. This quieter operation makes the Greenstar 4000 one of the quietest combi boilers on the market, so if you're fed up with your old boiler clunking and banging, this could very well be the upgrade your ears desire.</p>
<p><strong>Performance score: 5/5</strong></p>
<h3>Worcester Bosch Greenstar 4000: Cost</h3>
<p>When you're looking for a new boiler, cost is typically one of the significant factors you're going to consider. Compared to some brands in the boiler industry, the Worcester Bosch range carries a premium price tag, but the quality of the products certainly justifies this.</p>
<p>When shopping for a new appliance, it's important to note that the cheapest boiler upgrade may not be the most suitable for your home. Instead, you need a boiler that can handle the demands of your home and offer good value for money.</p>
<p>To select the right <a href="https://www.boxt.co.uk/boilers" rel="follow">boiler</a>, enter your postcode to begin. We ask for a few key details about your current heating system and the size of your home, then recommend suitable boilers for you. It's that easy.</p>

We&rsquo;ll also carry out a chemical flush as standard to ensure your central heating system is clear of any dirt, debris, rust, and other contaminants.</p>
<p><strong>Cost score: 4.5/5</strong></p>
<h3>Worcester Bosch Greenstar 4000: Ease of use</h3>
<p>With a full-colour LCD display panel, the controls of the Greenstar 4000 are easy to follow and programme. While the ease of use may not be at the top of your list of boiler must-haves, it is a crucial consideration, especially if something goes wrong.</p>
<p>Plus, it's compatible with a range of thermostats to schedule your boiler's heating for optimal performance and comfort.</p>
<p><strong>Ease of use score: 5/5</strong></p>
<h3>Final scores</h3>
<p>As we have explored above, Worcester Bosch boilers are some of the most reliable on the market, and the Greenstar 4000 heating systems continue this trend as one of the best boilers available.</p>
<p>With a <strong>final score of 24.5/25</strong>, the energy-efficient Greenstar 4000 is a fantastic option for your next boiler. And, if you're thinking of upgrading, look no further than BOXT.</p>

Worcester Bosch Greenstar 4000 - boiler review

Wondering what to do if you can't afford a new boiler and your current appliance breaks down? Here, we explore the grants and short-term solutions available.

<p>Buying and installing a <a href="https://www.boxt.co.uk/boilers" rel="follow">new boiler</a> is expensive, especially if the news comes as a shock to you and you haven&rsquo;t yet had a chance to put money aside.</p>
<p>Luckily, to help you manage the cost of a new boiler, there are things you can do, including accessing government schemes, spreading the cost, and exploring short-term alternatives to using your boiler.</p>
<h2>Grants and funding available to help you pay for a new boiler</h2>
<p>The Government offers several boiler grants and schemes to help people stay warm and reduce the nation's carbon emissions. These are specifically designed to help low-income households most at risk of fuel poverty and the effects of the cost of living crisis.</p>
<p>It&rsquo;s worth noting that the availability of any schemes may change over time, with certain offerings coming to an end each tax year. Be sure to check on the official website for the most up-to-date guidance.</p>
<h3>Energy Company Obligation (ECO)</h3>
<p>Sometimes known as the free boiler scheme, the Energy Company Obligation (ECO) was initially set up in 2013 and is now in its fourth and final phase, which is set to end on March 31st 2026.</p>
<p>This 'free boiler grant' was set up to help people living in households with an energy performance certificate rating of D-G access funding to pay for things like energy-efficient boilers, cavity wall insulation, and double glazing.</p>
<p>Energy suppliers pay for the ECO scheme, and those eligible for funding can access money to improve their home&rsquo;s energy efficiency rating.</p>

To see whether you could be eligible for funding and learn more, look at our blog - "what is the ECO4 scheme?"

What is an ECO4 scheme?

<h4>Local Authority Flex &amp; Delivery Scheme (LADS) funding</h4>
<p>Another part of the ECO4 is LA Flex, which allows councils and local authorities to widen the scheme's eligibility criteria to provide support for residents in their areas. Using LA Flex, households can still buy new boilers and take steps to reduce fuel poverty and energy bills.</p>
<h3>Boiler Upgrade Scheme (BUS)</h3>
<p>This scheme was set up to help people replace an old oil or gas boiler with a new, low-carbon heating system, like a heat pump or biomass boiler.</p>
<p>Depending on the type of appliance you want to buy, you'll either be able to get grants for &pound;7,500 (air or ground source heat pumps) or &pound;5,000 (biomass boiler).</p>
<p>Discover more information about all of these funding schemes and their eligibility criteria in our '<a href="https://www.boxt.co.uk/boilers/guides/boiler-grants-everything-you-need-to-know" rel="follow">Everything you need to know about boiler grants</a>' guide.</p>
<h2>Spreading the cost of your new boiler</h2>
<p>If paying for a new boiler in one upfront sum isn&rsquo;t possible, there are ways you can spread the cost to make it more affordable.&nbsp;</p>
<h3>&nbsp;Getting a new boiler on finance</h3>
<p>At BOXT, we&rsquo;re working to make the home heating and cooling industry fairer and more affordable, one A-rated appliance at a time. One of the ways we do this is by giving you the chance to spread the payment of a new boiler over a period of 12-120 months.&nbsp;</p>
<p>This enables you to get an A-rated boiler and pay it off in manageable instalments.&nbsp;</p>
<p>Better still, there&rsquo;s 0% interest charged when you spread the cost over up to 2 years.</p>

Get a brand-new A-rated boiler on finance today.

<h3>Signing up for a boiler subscription service</h3>
<p>With a subscription to BOXT Life, you can get an A-rated boiler installed by a Gas Safe registered engineer, as well as annual servicing and unlimited boiler repairs for &pound;33.35 per month. That's complete heating and hot water peace of mind for less than the average phone contract. And, the price is fixed for the full 10 years, so there are no price increases to worry about, just one flat rate and a boiler service you can trust.&nbsp;</p>
<h2>What are the signs you need to replace your boiler?</h2>
<p>Boiler breakdowns rarely happen out of the blue. Usually, there are telltale signs that something isn&rsquo;t working as it should, and acting on these promptly can reduce the likelihood of irreparable failures or even prevent the need for a replacement altogether.</p>
<h3>Repeated low pressure</h3>
<p>Several things, including water leaks or a faulty pressure relief valve, can cause low boiler pressure. Read &lsquo;<a href="https://www.boxt.co.uk/boilers/guides/why-does-my-boiler-pressure-keep-dropping" rel="follow">Why does my boiler pressure keep dropping?</a>&rsquo; for guidance on how to check if your boiler pressure has dropped and how to increase pressure to the optimal level.</p>
<p>However, if your boiler's losing pressure quickly, even after repeated repressurising, it may be a sign there's a more severe issue at play. Get in touch with a Gas Safe registered engineer to investigate as soon as possible.</p>
<h3>Running out of hot water</h3>
<p>Not only is a lack of hot water frustrating, but it may also be a sign that your boiler can't cope with your home's demands. If this is because your family has grown and more people want to use the bathroom, it may be time to consider a new boiler.</p>
<p>If you find that your boiler is on but not providing any hot water, this is also a sign that you might need a replacement. Read our complete guide on <a href="https://www.boxt.co.uk/boilers/guides/no-hot-water" rel="follow">what to do if you find yourself with no hot water</a> for more information and potential diagnoses.</p>
<h3>Higher than expected energy bills</h3>
<p>Modern boilers are much more effective than their predecessors, with all new boilers being <a href="https://www.boxt.co.uk/boilers/guides/what-is-a-condensing-boiler" rel="follow">condensing</a> and A-rated for energy efficiency. Essentially, this means that for every pound you spend on heating your home, only around 10p is wasted.</p>
<p>However, if you've had your current heating system installed for over 10 years, your boiler could be rated D or lower, meaning it wastes a large amount of energy when working to keep your home warm.</p>
<p>If you've noticed your energy bills getting more expensive, it could be a sign that you have an inefficient boiler, and it may be time to upgrade to a newer, more energy-efficient model.</p>
<p>Check out <a href="https://www.boxt.co.uk/boilers/guides/when-to-replace-boiler" rel="follow">7 signs you need to replace your boiler</a> guide for more indicators that it may be time for an upgrade.</p>

<p>In this guide, we explore why gas prices have increased and what the future could hold for our energy bills as we look ahead to 2024. But first, let's explore how energy prices are calculated and what affects the price of our gas bills.</p>
<h2>How are energy prices calculated?</h2>
<p>Energy prices are made up of different charges, including unit rates, standing charges, and taxes, including VAT.</p>
<ol>
<li>Unit rates are the price charged per unit of electricity or gas, measured in kilowatt-hours (kWh).</li>
<li>The standing charge is set by your energy provider and is incurred daily. Essentially, it&rsquo;s what you pay for being connected to the grid. Even if you don't use gas or electricity, you'll still have to pay a standing charge.</li>
</ol>
<h3>What are wholesale energy prices?</h3>
<p>Energy suppliers buy gas and electricity from companies on the wholesale market, and these fees make up about a third of your energy bill.</p>
<p>Wholesale energy prices are based on the global gas and electricity market, meaning they can fluctuate very quickly. Demand also plays a significant role in prices, so gas and electricity prices are typically higher in winter. &nbsp;</p>
<h3>What other factors affect gas prices?</h3>
<p>As well as the wholesale cost of gas and electricity, your energy provider will charge network costs - these contribute to the upkeep of the gas pipes and infrastructure that carry energy into your home or business.</p>
<p>Network costs vary from year to year; e.g. they may be increased to reflect usage or how funds need to be allocated to different parts of the network. Additionally, network costs cover 'balancing' charges, which help to ensure the constant supply and demand for electricity and gas can be accommodated.</p>
<p>Secondly, large suppliers are required to help pay for Government energy policies. These could cover schemes to support energy efficiency improvements and help vulnerable people.</p>
<p>Other costs that will impact your gas bills include:</p>
<ul>
<li>Meter maintenance and installation</li>
<li>Third-party services, including sales commissions</li>
<li>Smart metering programme costs</li>
<li>Administration from data and settlement services</li>
</ul>
<h2>What is the energy price cap?</h2>
<p>The energy price cap was introduced by Ofgem in 2019 and is designed to prevent people from being overcharged on their gas and electricity bills.</p>
<p>The price cap limits what you pay for the gas and electricity you use and sets a maximum daily standing charge. Amongst other things, the energy price cap is based on wholesale prices, but it only applies to the rates, so the more you use, the more you pay.</p>
<p>As of April 1st 2024, the current price cap level is &pound;1,690 per year for an average household paying by direct debit.</p>
<p>If you own your own company, you will already know that business energy prices are not capped and although business energy rates are falling, Government support has also been cut.</p>
<h2>Why are gas and electricity prices so high?</h2>
<p>Despite the energy price cap, prices have fluctuated for several reasons that have all created an array of problems, from Russia invading Ukraine to the energy crisis. These things have all seemingly happened at once, too, and, unfortunately, have impacted our energy bills considerably.</p>
<p>To help you understand why your bills have increased so much, here are the key reasons gas prices are so high.</p>
<h3>Long winters</h3>
<p>Over the last few years, it has felt like winter started in October and lasted right through until March. These longer cold spells have led us all to rely more on our heating. It's not just affected the UK, but the rest of Europe and parts of Asia.</p>
<p>These chillier temperatures have led to increased demand worldwide for gas, which in turn has reduced supplies more quickly.</p>
<h3>The war in Ukraine</h3>
<p>In solidarity with Ukrainians following the Russian invasion in February 2022, many European countries decided to cease purchasing oil and gas from Russia. Until then, Russian supplies accounted for approximately 40% of the EU&rsquo;s oil and gas, meaning countries have been forced to look elsewhere.</p>
<p>This now global supply versus demand deficit has contributed to price increases and caused panic buying, furthering the rate of inflation.</p>
<h3>Increased demand in other countries</h3>
<p>In recent years, Asian nations like China, Japan and South Korea have all bought large quantities of liquefied natural gas (LNG) to reduce their reliance on coal.</p>
<p>Similarly, South American countries have imported significantly more LNG. This increased demand has meant the UK cannot access the same supplies of LNG as it needs to keep prices down.</p>
<p>This combination of problems has increased the demand for gas worldwide, ramping up the pressures on gas exporters and driving up the cost of gas.</p>
<h2>Will energy prices be reduced?</h2>
<p>As the demand for gas reduces during the spring and summer months and we rely on our heating less, the energy price cap will most likely fall to reflect the differences in our heating habits. The price cap is also expected to rise during the winter; however, it is expected to be lower than in recent years.</p>
<p>While it is hard to estimate what will precisely happen to UK energy prices, many experts are forecasting that the energy price cap will fall over the next year. <a href="https://www.cornwall-insight.com/predictions-and-insights-into-the-default-tariff-cap/" rel="nofollow noopener" target="_blank">Cornwall Insight</a>, for example, has predicted that we could finish 2024 with an energy price cap of &pound;1,521.02, a reduction of over &pound;400 compared to the start of the year.</p>
<p>So, after the financial pressures of the last few years, we may have some good news to look forward to when future energy price cap levels are announced in the coming months.</p>
<h2>How can you keep your energy bills low?</h2>
<p>The first thing you can do is look at how much energy you're currently using and identify improvement areas. This could include spending less time in the shower or boiling the kettle with less water. These changes may seem small, but over a year, they will positively impact your bills.</p>
<p>Additionally, to help you save money on your energy bills, you can:</p>
<ul>
<li>Turn your thermostat down by one degree.</li>
<li>Use a smart meter to track usage and habits.</li>
<li>Invest in thermostatic radiator valves.</li>
<li>Ensure your boiler and heating system is suitable for your home.</li>
<li>Switch to alternative energy sources, e.g. by having <a href="https://www.boxt.co.uk/solar">solar panels</a> installed.</li>
</ul>

Why are gas prices so high?

Are you running into issues with your combi boiler? Read our guide on common combi boiler problems and how to fix them to restore order to your home.

<p><a href="https://www.boxt.co.uk/boilers/combi-boilers" rel="follow">Combi boilers</a>, sometimes known as combination boilers, are among the most popular home heating systems in the UK. They&rsquo;re energy-efficient, affordable, and compact, making them ideal for large numbers of households nationwide. &nbsp;</p>
<p>Combi boilers offer a wealth of advantages, but like any appliance, they are susceptible to the odd mishap.</p>
<p>If your home's boiler or central heating system isn&rsquo;t working as it should, it can feel like the end of the world, but don&rsquo;t worry&mdash;help is at hand.</p>
<p>In this guide, we&rsquo;ll help you troubleshoot some of the most common combi boiler problems so that you or your engineer can get things back up and running as soon as possible.</p>
<h2>The most common combi boiler problems</h2>
<p>Below are some of the combi boiler problems our engineers often encounter.&nbsp;</p>
<p>In most cases you will need to contact a Gas Safe registered engineer who&rsquo;ll be able to come and investigate.</p>

<h3>No hot water</h3>
<p>Finding yourself without hot water is one of the most common (but most irritating) combi boiler issues people encounter. This can present itself in a few different ways, which we'll go through below.</p>
<h4>1. There is no hot water, but the central heating is working</h4>
<p>Sometimes, your home's central heating will work as usual, but hot water won&rsquo;t come from your taps.&nbsp;</p>
<p>In this scenario, The two things listed below, amongst many others, could be causing this problem.&nbsp;</p>
<ul>
<li><strong>Faulty diverter valve</strong>: In a combi boiler, the diverter valve directs hot water to the taps or the central heating system. If the valve isn&rsquo;t working as it should, it may not switch to the hot water mode when required.</li>
<li><strong>Scale/magnetite buildup</strong>: Over time, the accumulation of scale or magnetite in a combi boiler&rsquo;s plate heat exchanger could restrict or even block the flow of water through it, which would cause the boiler not to produce hot water and potentially overheat.</li>
</ul>
<p>For any of the potential causes listed above, you must <a href="https://www.boxt.co.uk/boilers/boiler-repair" rel="follow">contact a Gas Safe registered engineer</a> to come and take a look.</p>
<h4>2. There is no hot water and no central heating</h4>
<p>Here are some likely causes of no hot water or central heating in your home:</p>
<ul>
<li>Loss of water pressure: A considerable loss of water pressure in the system can prevent the boiler from operating for both hot water and central heating. If there isn&rsquo;t enough water, it won&rsquo;t be circulating in the home and safety devices in modern boilers will prevent it from lighting to protect the boiler.</li>
<li>Faulty programmer or timer switch: A malfunctioning programmer or timer switch may not signal the thermostats or boiler to produce hot water or activate the central heating.</li>
<li>Ignition issue: Problems with the boiler's ignition system or electronic controls can prevent it from firing up for hot water or heating.</li>
</ul>
<p>To resolve these issues, you can try a manual reset by following the manufacturer&rsquo;s instructions or&nbsp;<a href="https://www.boxt.co.uk/boilers/guides/boiler-pressure" rel="follow">repressurising your boiler</a>. If neither of these fixes gets things back up and running, <a href="https://www.boxt.co.uk/boilers/boiler-repair" rel="follow">contact a Gas Safe registered engineer</a>, who can investigate further.</p>
<h4>3. There is hot water, but only when the heating is on</h4>
<p>If your combi boiler only produces hot water when the heating is on simultaneously, there will likely be an error.</p>
<p>Here are the main ones to look out for:</p>
<ul>
<li>Faulty diverter valve: As mentioned, this valve directs hot water to the heating system or the domestic hot water supply, depending on the user's selection. If the diverter valve is faulty or stuck, it may not move into the hot water position when required.</li>
<li>Faulty thermistor: If it is defective or malfunctioning, it can impact the boiler's ability to produce and deliver hot water on demand.</li>
</ul>
<p>Unfortunately, neither of these are DIY fixes. Contact a Gas Safe registered engineer to ensure your combi boiler&rsquo;s fault is investigated and repaired safely.&nbsp;</p>
<h3>Water leaking</h3>
<p>If your combi boiler leaks, you might first notice a drop in the water pressure in your system. When you look at the combi boiler, you might see a puddle forming or a stain beneath the appliance where water has gathered and dried.</p>
<p>Leaking water can indicate that internal components within the boiler are damaged and need replacing, such as the boiler's hydraulic blocks, O rings, seals and gaskets. Alongside this, leaking water out of your blow off pipe outside could mean you have a faulty pressure relief valve or issues with your boiler&rsquo;s expansion vessel.</p>
<p>If water is leaking from your boiler, the whole system must be inspected. These repairs are technical and can require specialist equipment, meaning you must <a href="https://www.boxt.co.uk/boilers/boiler-repair" rel="follow">contact a Gas Safe registered engineer</a> rather than trying to carry them out yourself.</p>
<h3>No pilot light</h3>
<p>If you have an older combi boiler that fails to ignite or shows signs of intermittent heating, there may be an issue with the pilot light. You can sometimes see your pilot light from outside your combi boiler via a sight glass.&nbsp;</p>
<p>The boiler's pilot light could be struggling to light for several reasons, including an issue with the gas supply or a blocked/dirty pilot burner assembly.</p>
<p>A Gas Safe registered engineer must investigate any combi boiler issues relating to gas supplies or faulty ignitions.&nbsp;</p>
<h3>Thermostat error</h3>
<p>If your combi boiler isn't responding to changes you're making on your room thermostat, there could be an error with your home's wireless network, or if you have a hard-wired thermostat, the thermostat itself could be faulty. Another telltale sign of a thermostat error is inaccurate temperature readings from the system and uneven heat distribution around the home.</p>
<p>The causes of a thermostat error can be things like incorrect wiring, signal loss, or boiler control board issues.</p>
<p>Here are some simple solutions that might help:</p>
<ul>
<li>Check the batteries if the thermostat is wireless</li>
<li>Reset the thermostat settings</li>
<li>Update the software</li>
</ul>
<p>If you&rsquo;ve tried the above DIY fixes and are still experiencing issues, <a href="https://www.boxt.co.uk/boilers/boiler-repair" rel="follow">get in touch with a Gas Safe registered engineer</a>. During a callout, they'll check your whole system and get to the bottom of any issues.</p>
<h3>Loss of pressure</h3>
<p>A loss of pressure within your combi boiler can cause your entire system not to heat up as it should and, in some cases, lead to what&rsquo;s known as a boiler lockout. Low water pressure can be caused by a system leak or other issues within the appliance, such as issues with the expansion vessels or pressure relief valve.</p>
<p>If you think low boiler pressure could be the cause of your boiler issue, you can check the pressure gauge on the front of the system. The needle should be sitting in the green zone between 1 and 2 bar. If your pressure is low, you can try <a href="https://www.britishgas.co.uk/the-source/fix-it-yourself/how-to-repressurise-your-boiler.html" rel="follow noopener" target="_blank">repressurising your boiler</a>.&nbsp;</p>
<p>If this doesn&rsquo;t work, you&rsquo;ll need to contact an engineer to come and take a look. They may need to repair or replace faulty components or carry out more complex maintenance on your home&rsquo;s central heating system.</p>
<h3>Strange noises</h3>
<p>Household appliances can make a selection of weird and wonderful <a href="https://www.boxt.co.uk/boilers/guides/9-reasons-why-your-boiler-is-making-a-noise" rel="follow">noises</a> as they serve your home, but sometimes, rumbles and gurgles can shed light on a more significant issue with your combi boiler.</p>
<p>If you hear bubbling and gurgling from your combi boiler, air could be trapped in the system, limescale buildup, a damaged pump, or low water pressure.</p>
<p>Because a number of different things can cause these strange noises, there are several DIY fixes you can try before <a href="https://www.boxt.co.uk/boilers/boiler-repair" rel="follow">calling an engineer</a>, including bleeding the radiators, checking the water pressure or adjusting the temperature settings.</p>

<h3>Frozen condensate pipe</h3>
<p>If you have a modern condensing gas combi boiler, it will have a condensate pipe and flue. Sections of these pipes sit outside your property, leaving any liquids inside at risk of freezing in sub-zero temperatures. Frozen condensate pipes are a common boiler issue in the UK during the winter months.&nbsp;</p>
<p>Symptoms can include gushing sounds from the boiler, frequent lockouts and visible ice on the outside of the pipe itself.</p>
<p>If you suspect your condensate pipe is frozen, you can try to reset the system. Or, if your condensate pipe runs externally, you could try thawing it by pouring hot (not boiling) water onto it. If neither of these fixes works, contact an engineer.&nbsp;</p>
<p>Here, you can read our complete guide on <a href="https://www.boxt.co.uk/boilers/guides/how-to-fix-a-frozen-boiler-condensate-pipe" rel="follow">how to fix a frozen condensate pipe</a>.</p>
<h3>Kettling</h3>
<p><a href="https://www.boxt.co.uk/boilers/guides/boiler-kettling" rel="follow">Kettling</a> is when water begins to boil inside the boiler. Even though this might not sound like a problem, the water inside your boiler (whether it&rsquo;s combi, system or standard) should never actually reach boiling point. If it does begin to kettle, it will generate steam inside the system and, as the name suggests, cause a loud rumbling or whistling noise, just like a kettle.&nbsp;</p>
<p>In terms of symptoms, you might notice a decreased efficiency with your system. This means it may cost more to heat your home, or your boiler won't be heating up as it should. It could also mean a potential fluctuation in boiler pressure.</p>
<p>The causes for kettling can vary, but some leading causes are limescale buildup, debris or sludge in the system, incorrect pump settings or a failure causing overheating.</p>
<p>If you're experiencing kettling in your combi boiler, don&rsquo;t try and fix it yourself. <a href="https://www.boxt.co.uk/boilers/boiler-repair" rel="follow">Contact a Gas Safe registered engineer</a> to come and service or repair the system.</p>
<h3>Cold radiators</h3>
<p>Everyone knows that sinking feeling when you think the heating is on, but your radiators aren't warming up as they should. Maybe you can feel cold patches on the bottoms of one or more of your radiators, or perhaps certain areas of your home feel warmer than the others.</p>
<p>If your <a href="https://www.boxt.co.uk/boilers/guides/radiator-cold-at-bottom" rel="follow">radiators are cold</a>, it can mean many things. If you have cold spots towards the bottom of your radiators, then there is more than likely magnetite or sludge in them, which has settled in the bottom, preventing correct heat transfer. This will require a <a href="https://www.boxt.co.uk/boilers/guides/power-flush" rel="follow">system flush</a> to remove the sludge and resolve the issue.</p>
<p>If they are cold at the top, this will more than likely be due to air trapped in them, and they need bleeding.&nbsp;</p>
<p>If air is trapped in your radiators this can be solved by bleeding your radiators. You can learn <a href="https://www.boxt.co.uk/boilers/guides/how-to-bleed-a-radiator" rel="follow">how to bleed a radiator</a> by reading our expert&rsquo;s guide.&nbsp;</p>
<p>If you've bled your radiators and they still aren't functioning as expected, then <a href="https://www.boxt.co.uk/boilers/boiler-repair" rel="follow">call an engineer</a> to take a closer look.</p>
<h3>Repeated lockouts</h3>
<p>Boiler manufacturers use the term boiler lockout when a boiler has shut down. When a boiler has a fault, the 'lockout' function shuts the system down to prevent further damage.&nbsp;</p>
<p>Depending on what kind of boiler you own, the interface may have a flashing light or an error code.</p>
<p>Combi boiler lockouts are usually because of one of the following reasons:</p>
<ul>
<li>Fan issues</li>
<li>Pump failure</li>
<li>Power cut</li>
<li>An ignition problem</li>
<li>A system blockage</li>
</ul>
<p>To fix a combi boiler lockout, you can try resetting the system and see if anything changes. Beyond this, frequent lockouts are a sign that your system needs to be examined, <a href="https://www.boxt.co.uk/home-cover" rel="follow">serviced</a> or repaired by a qualified boiler engineer.</p>

<p>When it comes to your heating system, it pays to know your way around it. This way, if any issues arise, you'll have a better idea of how to tackle them and get your home running as it should once again.</p>
<p>A handy tip in boiler maintenance is knowing how to reset your boiler. Below, we'll go through some of the most common models on the market today and how to reset them when the need presents itself.</p>
<h2>Safety precautions</h2>
<p>Resetting a boiler using the controls is not classed as working on the boiler, so homeowners can safely do this. Any more in-depth work must be performed by a qualified, Gas Safe registered engineer. If a problem persists after resetting the boiler, you should <a href="https://www.boxt.co.uk/boilers/boiler-repair" rel="follow">contact a Gas Safe engineer</a>, as there might be an underlying issue that resetting alone won&rsquo;t resolve.</p>
<h2>Signs your boiler might need to be reset</h2>
<p>It&rsquo;s important only to reset your boiler when something is actually wrong, which means it&rsquo;s important to be able to recognise the telltale signs of an internal issue somewhere in the system.</p>
<p>Here are some of the most common symptoms to look out for as a signal to reset your boiler.</p>
<ul>
<li><strong>No heating or hot water</strong>: If your boiler isn't performing as it should, it may benefit from a reset.</li>
<li><strong>Error codes</strong>: Fault or error codes are a great way to identify an issue with your boiler. If you check your boiler's manufacturer's notes, it may suggest resetting the boiler to tackle an error code.</li>
<li><strong>Thermostat malfunction</strong>: The boiler thermostat can sometimes stop working in sync with the system. Resetting the boiler can help get things working as they should.</li>
<li><strong>A power cut</strong>: If your home has suffered a power outage, there's a good chance your boiler will need to be reset, as it could have forced a boiler lockout.</li>
</ul>
<p>Whilst these symptoms can often be remedied with a simple reset, it is crucial that you do not carry out any work on your boiler. <a href="https://www.boxt.co.uk/boilers/boiler-repair" rel="follow">Get in touch with a Gas Safe registered engineer</a> if any issues with your boiler persist so they can investigate further and resolve any issues you still have.&nbsp;</p>
