Air Source Heat Pump Costs, Grants and Savings in the UK
An air source heat pump extracts heat from outside air to warm your home and hot water, typically replacing a gas, oil or LPG boiler. Here’s what UK homeowners typically pay, what grants are available, and what it saves on running costs.
What a heat pump costs
Because every home’s requirements differ, it’s nearly impossible to give an accurate installed cost from a page like this. The real figure depends on your home’s size and insulation, the heat pump capacity needed, and the installer you choose, among other things.

Running cost savings vs gas
Running costs are typically 30 to 70% lower than a gas boiler in a property with reasonable insulation, working out to roughly £540 to £1,000 a year depending on the system and how well-insulated the home is. That figure also reflects no longer paying for an annual gas boiler service, typically around £120 a year.
Payback period
Payback from running-cost savings alone depends on your current heating system and how well-insulated your home is. Homes with poor insulation will see a longer payback.
These figures are UK-wide averages for illustration, not a quote or guarantee of eligibility. Your actual cost, grant amount and savings depend on your current heating system, home insulation, location and the installer you choose.
