Home Energy Trends Report 2024


How are UK households managing their energy bills and consumption in 2024?

Like many parts of the world, the UK is caught in a cost of living crisis, with households tightening their belts wherever possible to make ends meet. One of the household expenses most impacted by recent inflation is the cost of utilities, with bills soaring up and down the country.

With the government, and homeowners, continuing to look at the most energy efficient solutions and products to combat these price increases, BOXT has produced this report to explore the home energy topics that are currently trending in the UK. 

The report covers:

  • Public interest in different types of energy efficiency solutions
  • The regions installing the most heat pumps, solar panels, and EV chargers
  • The most popular energy saving solution in each UK city 
  • The government energy schemes people are most interested in

Key findings

Heat pumps are the UK's leading home energy trend

Public interest in heat pumps has soared over the past year with internet searches rising by 160% in 2023 compared to the previous year. 

Heat pump technology is improving rapidly making them increasingly suitable and affordable for domestic use. The launch of the Boiler Upgrade Scheme in England and Wales, which provides grants to encourage property owners to replace existing fossil fuel heating with more efficient, low carbon heating systems including heat pumps, has been the driving force in increasing their popularity with 36,799 installed in 2023 compared to 29,490 in 2022 - a 24.8% increase.

Scotland is leading the way in heat pump and solar panel installations

Six of the top ten locations for heat pump installations are in Scotland with four of the top ten locations for solar panel installations also being in Scotland. 

With the Scottish government offering up to £15,000 in funding for heat pump installations, through a combination of a grant and an interest-free loan, and a greater number of homes in Scotland not connected to the mains gas grid, it is clear that heat pumps are a much more appealing offer, and cost-effective option for Scottish homeowners compared to those living elsewhere in the UK. 

Scotland is also leading the way with solar panel installations with, on average, over 5% of homes in Scottish local authorities having installed photovoltaic solar panels over the last ten years. As with heat pumps, the Scottish government offers both a grant and loan to homeowners installing solar panels and solar batteries which once again demonstrates how the removal of financial barriers can significantly improve the take up of renewable energy solutions.  

Public demand for government assistance with energy bills is huge, with more than 3.6 million annual searches for energy schemes.

Soaring home energy costs have led to the government introducing a number of schemes designed to help the most vulnerable households and those with outdated heating systems. The Cold Weather Payment, which is available to certain households if the average temperature in their area falls to zero degrees Celsius or below over seven consecutive days, is the most popular government scheme in the UK with almost 1.17 million searches in 2023.

What does this research tell us about the future of sustainability?

Andy Kerr, CEO & founder of BOXT the leading online installation platform for home efficiency solutions, comments:

“The desire for a sustainable and energy-efficient future for UK home heating is undeniably growing. 

“From this report, it is clear that to improve installation numbers of sustainable energy solutions, more needs to be done to make them more affordable. The Scottish government’s grant and loan scheme, which also includes hybrid heat pumps, has been hugely successful in driving up heat pump and solar installations. 

“We need our government to show a similar level of commitment in order for consumers to consider making the switch. Unfortunately, the delay to the start date of the Clean Heat Market Mechanism policy has only continued to unsettle the industry and cause confusion for consumers.

“It is highly likely that gas boilers will remain in many UK households in the coming years, whilst the heat pump technology continues to develop and consumers start to understand more about the most efficient use of heat pumps in their homes. 

“Homeowners need clear guidance about how home efficiency improvements can be made, including insulation requirements and radiator guidelines, which are vital for optimum heat pump performance - but can increase upfront installation costs. 

“A recent update to requirements for the Boiler Upgrade Scheme (BUS) means households are eligible for a grant even with cavity wall insulation recommendations on their EPC. Whilst this will help more households to access funding for heat pump installations, it needs to be made consistently clear that it will be the most well insulated homes that will see the most efficient savings and payback on their heat pump investment.

“Furthermore, if the move towards heat pumps is going to be successful, the current lack of skilled engineers for heat pump installations must be addressed urgently. To meet the growing demand, government initiatives and manufacturer courses to train engineers need to be launched quickly.”

“We’d like to see further expansion of the Boiler Upgrade Scheme to incorporate grants for hybrid heat pumps for England and Wales, following the successful implementation of hybrid heat pumps across Scotland — 2.1% of households in the country currently have a heat-pump heating system.

“At BOXT, we are committed to helping homeowners find the best possible solution to their home energy needs at the best possible price, whether that is a new, energy efficient boiler, a hybrid heat pump, or solar panels with battery storage.”

1 - Heat pumps

Annual Search Increase: 160%

Heat pumps are the biggest energy efficiency trend, with the most significant increase in search volume in 2023, with searches rising by 160% compared to the previous year. This increase in searches goes hand in hand with the rollout of the UK government’s Boiler Upgrade Scheme, suggesting that it successfully reached a broad audience and sparked public interest.

2 - Smart meters

Annual Search Increase: 115%

Smart meters saw the second-largest annual search increase, with 115% more searches in 2023 than in 2022. The UK government and energy companies have promoted smart meters for several years, and they continue to grow in popularity as the public becomes ever more familiar with the technology and is looking to stay more in control of energy usage amidst the cost of living crisis. 

3 - Energy-efficient appliances

Annual Search Increase: 25%

Searches for energy-efficient appliances saw the third largest increase, rising by a quarter from 5,910 in 2022 to 7,370 in 2023. This uptick in public interest correlates with the cost of living crisis that has sent bills spiralling in many households as many people look for ways to trim unnecessary spending.

Six of the top ten locations installing air source heat pumps are in Scotland


1 - Na h-Eileanan Siar

Percentage of households with installations: 15%

One in six households in the Outer Hebrides islands has had an air source heat pump installed in the last ten years. The Scottish Government has a net zero target of 2045 and aims to fulfil this (partly) by providing a £7,500 grant with the Home Energy Scotland Scheme for homeowners to install air source heat pumps. Data suggests these heat pumps are replacing oil heating systems, which are costly.

2 - Orkney Islands

Percentage of households with installations: 10%

Air source heat pumps are also seeing a significant uptake in installations in the Scottish Orkney Islands, with almost one in 10 households receiving the energy-efficient upgrade in the last ten years. Orkney is off the UK gas grid. Therefore, homes on the island mainly used oil-powered heating systems in the past. Since Scotland has a net zero target of 2045, many homes have switched to using air-source heat pumps for heating purposes.

3 - Argyll and Bute

Percentage of households with installations: 7%

Argyll and Bute is one of the Scottish local authorities leading the way with air source heat pump installations. Many domestic properties in the area have adopted heat pumps in the last ten years, as many rural homes on the inhabited islands do not receive a gas supply. Air source heat pumps are much more cost-effective than oil heating systems.

Scotland has more heat pumps per household than any other UK region


1 - Scotland

Average percentage of households with installations: 2.1%

On average, just over 2% of homes in Scottish local authorities have installed an air source heat pump over the last ten years. Scotland’s move towards renewable energy aligns with the Government's goal of achieving net zero emissions by 2045. It is also important to note that many heat pump installations nationwide are replacing oil heating systems in homes in rural areas not served by the gas grid.

2 - Wales

Average percentage of households with installations: 1.3%

Wales is close behind Scotland, with an average of 1.3% of homes across the country’s local authorities installing a heat pump in the last ten years. The country aims to generate 70% of electricity from renewable sources by 2030, and air-source heat pumps are among the most cost-effective, energy-efficient upgrades.

3 - South West

Average percentage of households with installations: 1.0%

On average, local authorities in England’s South West have one of the highest air source heat pump installation rates across all UK regions. The local authorities of South Hams, Cornwall, and Forest of Dean lead the way, with over 2% of homes installing a heat pump in the last decade. Many local authorities in the region are rural, coastal locations where access to mains gas may be limited or unavailable, which likely accounts for a proportion of heat pump installations.

Four of the top 10 locations installing solar PV are in Scotland


1 - Stirling - Percentage of households with installations: 14%

Almost one in six homes in Stirling have installed photovoltaic solar panels in the last ten years. While Stirling is far from the sunnier southern coast locations that might be expected to lead the way with solar installations, the area benefits from Government initiatives promoting the adoption of renewable energy and excellent grid connections. Schemes include the Feed-In Tariffs scheme, which allows homeowners to sell surplus electricity back to the grid.

2 - Isle of Anglesey

Percentage of households with installations: 11%

The Isle of Anglesey is one of the top local authorities for solar installations, with over one in 10 homes installing photovoltaic solar panels in the last decade. At the forefront of energy efficiency, the local authority is also one of the top 10 areas for air source heat pump installations. The island has many rural and farming households who benefit from generating their own electricity.

3 - Peterborough

Percentage of households with installations: 11%

Just over one in 10 households in Peterborough have introduced photovoltaic solar panels in the last decade. Peterborough gets among the most sunlight hours out of all areas of the UK. Therefore, residents in the local authority can benefit significantly from using solar panels to generate electricity.

Scotland has more solar PV installations per household than any other UK region


1 - Scotland

Average percentage of households with installations: 5.2%

On average, just over 5% of homes in Scottish local authorities have installed photovoltaic solar panels over the last ten years. This is likely primarily due to Scotland’s focus on renewable energy to achieve net zero emissions by 2045. Government grants for homeowners to install energy-efficient upgrades have also bolstered incentives.

2 - South West

Average percentage of households with installations: 4.9%

The South West follows closely behind Scotland, with an average of 4.9% of homes across all local authorities installing PV solar panels in the last ten years. The area benefits from a sunny climate and has excellent solar energy-producing potential.

3 - Wales

Average percentage of households with installations: 4.6%

Local authorities in Wales are among the top areas for installing solar panels, with an average of 4.6% of homes upgrading to renewable energy in the last decade. With excellent solar potential and many rural and farming households benefiting from producing their own power, it is unsurprising that Wales is at the forefront of solar installations.

Over the last year, 14,908 public EV chargers were added in the capital region, bringing London’s total number to 18,616, an increase of 61% from 11,521 in January 2023. 

In the past year, Westminster is the London borough where EV usage has grown the most. There was a 61% increase in the proportion of all licensed vehicles classified as electric or plug-in hybrids in the last year. This increase in EV usage matches the availability of chargers, as Westminster is also the local authority with the highest number of public EV chargers per 100,000 people, at 1,328. 

Outside of London, the English region with the most significant rise in public EV chargers was the North West, adding 1,311 chargers for an increase of 57%. In contrast, the North East was the English region with the lowest growth of 27.37% from 343 new public EV chargers being added. Barrow-in-Furness experienced the most significant change, with a 64% increase in the proportion of all licensed vehicles classified as electric or plug-in hybrids in the past year.

The UK country with the highest increase in public EV chargers is Wales, with 781 new chargers and a rise of 53%. This is higher than the overall increase for England, which sits at 47% and is the third highest rate compared to English regions. Meanwhile, Scotland saw the lowest growth of any country, with 834 new EV chargers translating to a rise of 22%.

2023 Additional Searches: 20,500

The Boiler Upgrade Scheme saw the third-largest increase of 36%, with an additional 20,500 searches in 2023. While the scheme was already popular in 2022, with 56,300 searches, the jump to 76,800 searches in 2023 shows that it has caught the public’s interest and continues to offer value to the British public who are concerned with both their bills and lessening their impact on the environment.

The Clean Heat Market Mechanism also saw impressive searches in 2023

Another new government energy scheme, the Clean Heat Market Mechanism (CHMM), also saw considerable searches, with 6,800 in 2023. As there were no searches for the scheme in 2022, we could not calculate a percent increase in search volumes, so were unable to include it in the above table.

The Clean Heat Market Mechanism is a scheme designed to ensure manufacturers of heating appliances increase the proportion of low-carbon heat pumps they sell compared to fossil fuel boilers. Under this mechanism, manufacturers would be fined £3,000 for every missed heat pump sale, encouraging a shift from more heavily polluting technologies to cleaner, cheaper alternatives. 

However, according to recent reports, there is a risk the scheme could be scrapped in 2024. The reason for the potential scrapping of the CHMM is concern that customers could foot the bill for fines levied against producers through increased prices. At the time of writing, this decision is still up in the air, with no public decision being made either way.

The Boiler Upgrade Scheme received the most applications per capita in South West England


South West England saw the highest rate of domestic applications to the Boiler Upgrade Scheme in England and Wales, with 18.17 applications per 100,000 people across all boiler upgrade types. This is almost double the overall rate for England and Wales, which sits at 9.31 applications per 100,000 people. The next-highest rate was seen in the South East, where applications reached 11.74 per 100,000, highlighting the lead the South West has built up in updating their boilers to newer technologies.

South West England topped the table for ground-source and air-source heat pumps, with application rates of 0.79 and 17.09 per 100,000 people, respectively. Again, these rates were considerably higher than the next-highest, with the South East having the second-highest rate of air-source heat pump applications at 11.49 per 100,000, while Wales has the second-highest rate of ground-source heat pump applications at 0.40 per 100,000.

Domestic applications for boiler replacements were also made for biomass boilers, though these typically saw the lowest rates of the three featured technologies. However, Wales bucked the trend in this instance, receiving the highest rate of applications with 0.64 per 100,000 people. The next highest rate was seen in the South West, where it reached 0.25 applications per 100,000 people, while the North East took third place with a rate of 0.24.

London saw the lowest rate of applications to the Boiler Upgrade Scheme

The capital region of Greater London saw the lowest overall rate of applications to the Boiler Upgrade Scheme, with just 3.66 per 100,000 people. Additionally, the London region recorded the lowest number of applications for each type of boiler upgrade, with application rates of 3.61 per 100,000 for air-source heat pumps, 0.04 for ground-source heat pumps, and a rate of zero for biomass boilers.

The North East and the North West saw the next-lowest rates of applications to the Boiler Upgrade Scheme, at 5.47 and 5.59 applications per 100,000, respectively. Interestingly, though, the South East of England saw the next-lowest rate of applications for biomass boilers, with just 0.01 per 100,000 people, followed by the East of England and the East Midlands with rates of 0.03. This indicates that biomass boilers are much less popular the further South and East you travel in the United Kingdom.


We wanted to compare various energy-related government schemes currently being rolled out in the UK. To do this, we used Google Keyword Planner to compare search volumes for 18 UK schemes and grants from Ofgem and GOV.UK

This search data was collected for 2022 and 2023 for each country in the UK. We revealed the most popular trends in the UK and each constituent country in 2023 and revealed which trends saw the most significant increase in interest from 2022.

Applications for the Boiler Upgrade Scheme were compared to see which parts of the country were most interested in the scheme. This was done using data from GOV.UK.

Also using GOV.UK data, we compared the number of public EV chargers in different parts of the country and looked at where the number of chargers had increased the most.

We sourced the percentage of all licensed electric vehicles and plug-in hybrids in each local authority using the Department for Transport Vehicle licensing statistics data tables: Table VEH0105 looking at vehicles of all keepership and body type as of 2023 Q3. We calculated the one-year percentage change by comparing this figure to the licensed vehicles in 2022 Q3.

We also wanted to analyse the popularity of various energy efficiency trends in the UK. We used Google Keyword Planner to record search volumes for 26 energy efficiency trends in the UK and the top 20 most populated towns and cities according to census data gathered via City Population

This search data was collected for 2022 and 2023, allowing us to reveal the most popular trends in the UK and each city per 100,000 people and the year-on-year increase in search volumes.We sourced the percentage of households with PV solar and air source heat pump installations between 2014 and 2024, as of 19/02/2024, using the MCS Data Dashboard, looking at domestic and commercial installations across local authorities. We then used each local authority’s major UK region to calculate the regions with the highest average percentage of households with PV solar and air source heat pump installations.
