You could receive £7,500 towards an air source heat pump through the UK government’s Boiler Upgrade Scheme.
If you’re looking to replace your gas, oil, or LPG boiler with a cleaner, more efficient heating system, you may be eligible for a government-backed air source heat pump grant. Improveasy helps homeowners check eligibility, apply for funding, and install heat pumps through trusted, accredited installers all in one managed service.
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.
Eligibility rules can be nuanced that’s why we offer a free eligibility check.
The Boiler Upgrade Scheme (BUS) is the UK government’s main programme supporting low-carbon heating. It offers a fixed £7,500 grant towards the installation of an air source heat pump.
You may qualify if:
The Warm Homes Plan is designed to help households move away from fossil-fuel heating by making low-carbon upgrades more affordable. Depending on your circumstances and property, it may provide additional funding support to reduce the upfront cost of installing an air source heat pump alongside other schemes such as the Boiler Upgrade Scheme.
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.
With the Boiler Upgrade Scheme applied, the cost of an air source heat pump is significantly reduced.

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.
Most installations take 2–4 days, depending on the property.
