What moves the price
- Heat pump size — a small terrace needs a smaller unit than a large detached house with high heat loss
- Radiator upgrades — heat pumps run at lower temperatures, so larger radiators are often needed
- Hot water cylinder — most installs need a new cylinder and space to put it
- Insulation — a well-insulated home needs a smaller, cheaper heat pump
- Pipework — narrow microbore pipes may need replacing to carry enough flow
- Grant — the Boiler Upgrade Scheme can take a large sum off the installed price
Plumbing and heating prices in the UK are up 6% over five years (ONS Consumer Price Inflation, Services for maintenance and repair, to 2026 August). Five years ago a typical air source heat pump would have cost about £11360 — an estimate from today's guide price and that index, not a recorded price. Source: ONS MM23 D7DO →

How to pay less
- Apply through an MCS installer for the Boiler Upgrade Scheme grant towards the heat pump
- Improve loft and wall insulation first so a smaller, cheaper heat pump is enough
- Keep existing radiators where the heat loss survey shows they are already large enough
Before you book
- Use an MCS-certified heat pump installer, which the Boiler Upgrade Scheme requires
- Many air source heat pumps are permitted development, but check siting rules, noise limits and listed buildings
- Check there is room for a hot water cylinder, or talk through with the heat pump installer where one could go
- Ask for the heat loss survey and expected running costs in writing before you commit
