What you actually pay

A typical air source heat pump for a 3-bed semi lands between £9,000 and £13,000 fitted. Take £7,500 off with the Boiler Upgrade Scheme and you are looking at £1,500 to £5,500 out of pocket.

If your home is off the gas grid and runs on oil or LPG, the grant rises to £9,000 for applications submitted from 21 July 2026, so the out-of-pocket figure drops further.

Ground source costs far more because of the groundwork. It only makes sense if you have the land and plan to stay put for a long time.

What pushes the price up

Bigger homes need a bigger unit and more radiator changes. Poor insulation forces a larger heat pump, so fixing draughts and loft insulation first usually saves money.

Coming from a combi boiler means a new hot water cylinder and somewhere to put it. That alone adds £800 to £1,800 plus the pipework.

Heat pumps run at lower flow temperatures, so some radiators need to be larger. An installer will tell you which ones after a room-by-room heat loss survey.

Frequently asked questions

An air source heat pump typically costs £9,000–£13,000 fitted for a 3-bed semi in 2026, and £12,000–£17,000 for a larger detached home. Ground source runs £20,000–£35,000 because of the ground loop.

The Boiler Upgrade Scheme pays £7,500 for air source and ground source heat pumps, and £9,000 where the property is off gas grid and heated by oil or LPG, for applications from 21 July 2026. Most households end up paying £1,500–£5,500 themselves.

Not always. Heat pumps run cooler than a gas boiler, so some rooms need larger radiators. A heat loss survey tells you which. Budget £120–£400 per radiator changed.

Yes, unless you already have one. Heat pumps cannot heat water on demand like a combi, so a cylinder is part of nearly every install. Expect £800–£1,800 plus fitting.

An air source install usually takes two to three days. Ground source takes one to two weeks because of the excavation or borehole work.
