Even if your current boiler is still working, it can be worth investing in a new boiler before you're stuck without heating or hot water when you need it, especially if your boiler is more than 15 years old.
A key reason it's worth upgrading older boilers is because modern boilers are more energy efficient than old ones. In fact, depending on how old your existing boiler is and the type of home you live in, you could save almost £500 a year on your energy bills with a new, A-rated boiler! Plus with the addition of smart technology, like the Google Nest Learning Thermostat, it's simple to build a heating schedule and control the temperature in your home from anywhere. In fact, this extra efficiency can help save up to an extra 10% on your heating bills.
