The questions people ask

What is the Boiler Upgrade Scheme?

A government grant in England and Wales towards replacing fossil fuel heating (gas, oil, LPG or electric) with a heat pump or biomass boiler. An MCS certified installer applies to Ofgem and takes the grant off your bill.

What are the scheme's main rules?

You can get one grant per property. The grant is £7,500 for an air source (air-to-water) or ground source heat pump, £5,000 for a biomass boiler and £2,500 for an air-to-air heat pump. Until 31 March 2027 the grant for an air-to-water or ground source heat pump is £9,000 in a property off the gas grid that is replacing oil or LPG heating (from 21 July 2026). Air-to-air heat pumps are for residential properties only. You cannot get a grant for a hybrid system such as a gas boiler with a heat pump, or to replace an existing low carbon heating system. The installer must commission and install the heat pump within 120 days of applying for the grant. Most new build properties and social housing are not eligible; biomass boilers must be in rural, off-gas-grid properties. The installer applies on Ofgem's website and the grant is taken off the price shown on the quote and invoice. The 2026 amendment regulations added air-to-air heat pumps, removed the need for a property to have a valid EPC and extend the scheme through to 2030. The Boiler Upgrade Scheme (England and Wales) (Amendment) Regulations 2026 came into force on 28 April 2026. Ofgem runs the scheme for the Department for Energy Security and Net Zero; Ofgem's BUS enquiry line is 0330 053 2006.

Who qualifies for the Boiler Upgrade Scheme?

You own the property, including a business, second home or a property you let to tenants. You are replacing a fossil fuel system such as oil, gas, electric or LPG heating. The property is in England or Wales. Earlier insulation funding does not stop you applying.

Air source (air-to-water) heat pump: £7,500. Ground source or water source heat pump: £7,500. Biomass boiler: £5,000. Air-to-air heat pump (homes only): £2,500. Air-to-water or ground source heat pump in an off-gas-grid home replacing oil or LPG, until 31 March 2027: £9,000.

What are the key dates?
