Having a brand new boiler installed means it will be working to the most efficient standard, which will benefit your home and also your bank account. Older boilers can work at efficiency levels as low as 40% whereas newer modern boilers can work at efficiency levels of nearly 90% meaning the strain on heating your home is considerably less.


If your boiler cannot be repaired we also specialise in boiler installation. Replacing your boiler has many benefits including saving energy which will in turn save you money on your energy bills. The older a boiler is the less efficient it becomes meaning it works harder to heat your home which costs you more money.

This means that less gas is needed to deliver hot water resulting in a saving to £377 a year.
