We can only offer air source heat pumps (ASHPs) under the Boiler Upgrade Scheme (BUS). The Boiler Upgrade Scheme (BUS) grant provides eligible homeowners in England with £7,500 towards the cost of installing an air source heat pump. Off-gas homes that currently use oil or LPG may also qualify for an additional £1,500, available until March 2027. We can help you check whether your property is eligible and guide you through the grant process.
