Average Cost to Install an Air Source Heat Pump in the UK (2026 Guide)
If you’re researching “heat pump cost UK” or “air source heat pump installation cost 2026”, you’ve probably noticed a huge range of figures online. In the UK, the average cost to install an air source heat pump (ASHP) before government support is typically between £7,000 and £15,000 depending on the size of your property, the type of system, and any additional work required such as radiator upgrades or insulation improvements. Larger homes and more complex installs can push costs toward the higher end of that range.
According to recent industry data, the average installed price for an air source heat pump is around £12,500, which includes installation by a certified installer. Without support, this can seem significantly more than replacing a gas boiler but that’s where UK government schemes come in.
How the Warm Homes Scheme & Grants Reduce Costs
One of the biggest drivers in making heat pumps affordable is the UK government’s Warm Homes Plan, a multi‑billion‑pound initiative that includes the Warm Homes: Local Grant and continuation of the Boiler Upgrade Scheme (BUS). The Warm Homes Plan allocates funding to help upgrade homes with energy efficiency measures, including heat pumps and insulation, often with local authority support guiding you through the process. Households could receive significant funding in some cases up to around £30,000 in total for improvements depending on local delivery arrangements and survey results.
Under the Boiler Upgrade Scheme, eligible homeowners in England and Wales can receive a £7,500 grant towards an air source heat pump installation. This grant is typically deducted directly from the installer’s price, meaning many UK households end up paying around £5,000 or less out of pocket after the funding is applied.
In addition to the grant, 0% VAT on heat pumps and associated systems continues to run until at least 2027, further reducing upfront investment.
Why It’s Worth Considering
Switching to an air source heat pump not only qualifies you for government support, it also helps cut long‑term energy bills and significantly reduces carbon emissions compared to fossil fuel boilers. Unlike traditional heating systems, ASHPs extract heat from the outside air, even in colder months, providing efficient heating and hot water with lower running costs.
