Air-to-air heat pumps

Air-to-air heat pumps

An air-to-air heat pump takes heat from the outside air and blows it into your rooms as warm air, using indoor units like those used for air conditioning. Run in reverse, the same system cools in summer. It does not heat hot water, so it suits homes that heat water separately or electrically.

Is there a grant for air-to-air heat pumps?

Yes, for eligible homes in England and Wales. Since 28 April 2026 the Boiler Upgrade Scheme 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 able to meet the home's full space-heating demand, and be fitted by an MCS-certified installer. We check eligibility with you on survey and confirm whether an MCS-certified installer is available for your job before you commit.

How efficient are they?

Air-to-air heat pumps usually produce three to five units of heat for every unit of electricity in mild weather, and less in very cold weather. That makes them far cheaper to run than direct electric heating such as storage heaters, panel heaters or electric fires.

Do they work in a British winter?

Yes. Modern units are designed to keep heating well below freezing. We size the system for a cold winter day in your area, not an average one.

The £2,500 air-to-air grant applies only to eligible homes in England and Wales, using an MCS-certified heat pump installed by an MCS-certified installer, who applies for the grant and deducts it from the price. We confirm eligibility, and which installer applies, before you commit.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.

UK middle prices. London and the South East are typically higher and much of the North, Scotland and Wales a little lower; see your area page for a local figure.

FAQ

Air-to-air heat pumps: your questions

Can an air-to-air heat pump replace my boiler?

It can replace the space heating, but not hot water. If any gas, oil or LPG boiler stays in use, even just for hot water, the installation does not qualify for the grant, and the heat pump itself must be MCS-certified.

How much is the Boiler Upgrade Scheme grant for air-to-air?

Ofgem lists £2,500 for air-to-air heat pumps in residential properties in England and Wales. Your installer applies and deducts it from your quote.

Is an air-to-air heat pump just air conditioning?

Technically it is the same kind of equipment, but it is designed and sized to heat the home through winter, with cooling as a bonus.

Will my energy bills go down?

If you are replacing direct electric heating, almost certainly. If you are replacing gas, savings depend on tariffs. We give an honest running-cost comparison at survey.
