Save Energy with a New Boiler

Boilers that are over 10-15 years old perform much less efficiently than their modern equivalents. A typical 15 year old boiler can waste as much as 40% of the energy it produces, meaning it’s only 60% efficient, this is equivalent to a G rating. The older the boiler, the less energy efficient it will be.

We work with some of the most trusted and reliable brands in the industry, Worcester Bosch, Glow Worm, Vaillant and others, so we can offer a range of A-rated energy efficient boilers for you to choose from. New boilers are designed to operate at 90% efficiency, or more.
