What Is an Air Source Heat Pump Grant?

An air source heat pump grant is financial support provided by the UK government to help homeowners switch from fossil-fuel heating to low-carbon heating systems.

The main grant currently available is delivered through the Boiler Upgrade Scheme, which provides £7,500 off the cost of installing an air source heat pump in eligible homes.

This grant is paid directly to the installer meaning you pay less upfront, with no complex claims or reimbursement process.

Unlike fixed grants, the Warm Homes Plan takes a more flexible, case-by-case approach, helping eligible households access the right mix of funding, support, and affordable finance.

How Does an Air Source Heat Pump Work?

Air source heat pumps extract heat from the outside air and use electricity to raise it to a usable temperature for heating your home and hot water. Even in cold weather, they operate efficiently and consistently.

They’re designed to work best in well-insulated homes and deliver lower running costs compared to traditional boilers.
