"Time for a new boiler? "

Your boiler is one of the hardest-working appliances in your home.

But if it’s old and breaks down, you’ll wish you’d replaced it sooner.

Replacements pay off

While regular servicing can help to keep your boiler working safely and efficiently, old boilers can be more expensive to run, so it could pay off to replace it.

But a new, efficient boiler can do more than shrink your energy bills by up to £315 a year 1. By helping you save energy, it’ll boost your journey to zero-carbon too.

Thinking of buying a new boiler? Read our guide on the different types of boilers and how to find the right for you.
