UK Energy Upgrade

Free Boiler Upgrade

Replace old, inefficient gas boilers with modern A-rated condensing models under UK energy company eco-grants.

Service Overview

If your gas boiler is more than 10 years old, it could be running at less than 60% efficiency, meaning that 40% of the gas consumed is wasted. Modern condensing boilers are A-rated and operate at over 92% efficiency. Under the ECO4 grant scheme, we help eligible homeowners replace old non-condensing, back-boilers, or faulty boilers completely free of charge. We replace your old unit with a premium A-rated combi boiler, flushing your radiators to remove blockages and optimize the entire system.
