Grants & funding
The Boiler Upgrade Scheme (BUS) gives English and Welsh homeowners £7,500 off an air-to-water, ground source or water source heat pump — rising to £9,000 for off-gas-grid properties applying between 21 July 2026 and 31 March 2027. Your installer applies and deducts it from your quote.

Support schemes only
There is no NI equivalent of the Boiler Upgrade Scheme. Check NI Direct for the energy efficiency support that is available, and ask installers about manufacturer or supplier offers.
Eligibility
Landlords: You can claim BUS for properties you let out, subject to a limit per applicant. The April 2026 amendment removed the blanket EPC and insulation condition, but your installer still has to show the property is suitable and that the system will perform — so poor insulation can still stop a job going ahead.
