Domestic Boiler Energy Performance Certificates (EPC’s)
Gas boilers are graded on an A – E basis with A rating being the highest. All domestic hot water boilers currently installed in the UK must be A Rated, they must have a rating of at least 90% efficiency.
Any replacement boiler installed via the Government boiler scheme will be an A-Rated boiler. A rated boilers reduce energy bills because they use less power / energy to heat your heating / hot water. They help the Carbon Footprint of the country because they lower the level of Carbon Dioxide released into the environment.
