Heat pump grants: the Boiler Upgrade Scheme

Q: Am I eligible for the Boiler Upgrade Scheme grant?

To be eligible for the £7,500 grant: 1) You need to be a homeowner in England or Wales. 2) You need to be replacing a fossil fuelled heating system (e.g. a gas, LPG or oil boiler) or direct electrical heating (e.g. storage heaters). 3) Your installer must be certified with the Microgeneration Certification Scheme. 4) You will need a valid EPC (Energy Performance Certificate).

The Boiler Upgrade Scheme has evolved!

The government has reaffirmed its commitment to grant funding for homeowners wanting to install a heat pump. In headline terms:

Grant allowance

The amount you can get remains at £7,500 for eligible households and air source heat pumps, but will increase to £9,500 for homes using LPG and Oil soon!

Application deadline

As things stand, the BUS grant is due to be available until 2028, but there's a fixed budget and increasing demand so act now.

More tech options

Air to air heat pumps, as well exhaust air heat pumps, are now also eligible for funding (as of 28th April 2026), but at a reduced grant rate of £2,500

You can get moving now and grab your funding voucher whilst it’s all still available.
