Most Efficient Combi Boiler Choices for UK Homes

Table of Contents

Looking to upgrade your home’s heating system? You’ve come to the right place. Choosing the most efficient combi boiler is not just about staying warm but also saving money on your energy bills, with homes reducing their annual bills by more than £550. Here at ECO Boiler Grants, we’re dedicated to equipping UK homeowners with the information they need to make informed decisions that transform their homes into energy-efficient comfortable living spaces.

Why Boiler Efficiency Matters More Than Ever

With UK energy costs continuing to increase, how efficient your boiler is has never mattered more. Condensing boilers, now a norm in the UK since 2005, are designed to recapture and reuse heat that would otherwise be wasted through the flue. This new technology enables the most efficient gas boilers currently on the market to have efficiency levels of up to 99%, a considerable difference from their predecessor, which can achieve a maximum of 70% efficiency.

Government funded schemes like the ECO4 scheme can fund heating system upgrades, including the full replacement of your old boiler with a new A-rated combi boiler. Fill in our 1-minute eligible form and find out if you qualify now!
