Choosing an A-rated combi boiler is essential for anyone looking to improve home heating efficiency while saving on energy costs. A-rated boilers are recognised for their high performance and reliability, making them a popular choice for homeowners.
What Makes an A-Rated Combi Boiler Efficient?
The energy rating system measures the efficiency of boilers, with A-rated boilers being the most efficient, using over 90% of the fuel to generate heat.

This reduces waste, lowers energy bills, and makes these boilers an eco-friendly choice. If you’re considering an upgrade, Kentish Plumbers offers installation and advice on a range of A-rated boilers.
