Short answer: Since 28 April 2026 the Boiler Upgrade Scheme in England and Wales has included air-to-air heat pumps, with Ofgem listing a £2,500 grant for residential properties. The system must replace existing fossil fuel or electric heating, be capable of meeting the home's full space-heating demand, and be installed by an MCS-certified installer, who applies for the grant and deducts it from the price.
What the law changed
The Boiler Upgrade Scheme (England and Wales) (Amendment) Regulations 2026 made air-to-air heat pumps eligible plant, for domestic properties only, from 28 April 2026. The same regulations removed the requirement for a valid EPC and require installers to deduct the voucher value from the quoted price.
Who is eligible
Homeowners and landlords in England and Wales replacing fossil fuel or direct electric heating. The heat pump must have enough capacity to meet the full space-heating demand on its own and be no more than 45 kW. If any gas, oil or LPG boiler stays in use, even just for hot water, the installation is not eligible, and the heat pump itself must be MCS-certified. Non-residential buildings are excluded.
The MCS requirement
Only installers certified by the Microgeneration Certification Scheme for air-to-air heat pumps can apply. Certification for air-to-air was still rolling out in 2026, so ask any installer to confirm their MCS status before you sign. We confirm whether an MCS-certified installer is available for your job before you commit.
Hot water
Air-to-air heat pumps heat rooms, not water. Homes need a separate way to heat water, such as an existing immersion cylinder or a hot water heat pump.
