About CoolGrant

CoolGrant is a plain-English guide to the Boiler Upgrade Scheme, focused on air-to-air heat pumps — the wall-mounted units most people call air conditioning. We help you check in a minute whether the £2,500 grant applies to your home, then introduce you to MCS-certified installers who apply for the grant on your behalf.

We're funded by installers when they take on the jobs we introduce. The site is written for the homeowner, and every result is indicative until a certified installer confirms it against current Ofgem guidance.
