UK grants for heat pumps & home energy

Cooling-only air conditioning isn't grant-funded in the UK — but heat pumps, which heat and (in some cases) cool your home, often are. Here's what's available in 2026, in plain English.

Can I get a grant for air conditioning?

Not for cooling-only units. The one exception is the new £2,500 Boiler Upgrade Scheme grant for air-to-air heat pumps (which can cool as well as heat). It became law in April 2026, but as of mid-2026 it isn't yet practically claimable — the certification needed by installers is still being finalised. We'll update this page the moment it goes live.

England & Wales

Boiler Upgrade Scheme (BUS)

Open
£7,500 (air/ground source) · £2,500 (air-to-air) · £5,000 (biomass)

Property owners in England & Wales replacing a fossil-fuel or standard electric heating system (you cannot already have a heat pump). An MCS-certified installer is required and there is one grant per property. The old EPC requirement was removed in April 2026.
