A Government Grant to Help You Switch
The Boiler Upgrade Scheme (BUS) is a government-backed grant designed to encourage homeowners in England and Wales to replace old, inefficient gas or oil boilers with low-carbon alternatives like heat pumps.
T
hrough the scheme, eligible households can claim up to £7,500 toward the installation of a new Air Source or Ground Source Heat Pump. This reduces the upfront cost significantly, making renewable heating more accessible and affordable.
The scheme is straightforward: apply once, and if you’re approved, the grant is paid directly to your installer, who deducts it from your bill. That means less hassle for you and an immediate reduction in costs.
