Our premium A-Rated boilers can save the average British household up to £340 per year on energy bills, and if installed with a smart thermostat, this can be upwards of £510 per year. There has never been a better time to upgrade your old inefficient boiler.

Free Survey Visit.

Unlike a lot of companies on the internet that allow you to purchase a boiler with a few questions, we offer a free survey before you decide to purchase.

We will ensure that you receive the right boiler for your home, including an industry-leading guarantee of up to 12 years.


Your Boiler Controls 60% of your Energy Bill.

Surely it should help you save money? With every boiler installed, we can install a smart thermostat that learns from you. It gets to know the temperature you like when you’re at home and turns itself down when you’re away.

It even learns how your home warms up or how draughty it is, so it only uses the energy it needs.


Advantages of a New Combi Boiler

Instant Hot Water
By installing a combi boiler, you can provide the house with on-demand hot water because there is no water tank, there is no waiting time!

Efficient and Economical
Combin boilers are highly efficient, producing condensation in order for more energy to be used rather than wasted. They can also only heat the water, enabling you to potentially make huge savings on your energy bill. You could save up to £350 per year.

The cold water that is released from a combi boiler is safer for you to drink as it is fed directly from the mains. This is not always the case with conventional boiler systems, as they tend to store cold water in tanks.
