Boiler Upgrade Scheme (BUS)

The Boiler Upgrade Scheme (BUS) supports the decarbonisation of heat in buildings. It provides upfront capital grants to support the installation of heat pumps and biomass boilers in homes and non-domestic buildings in England and Wales.

On Thursday 21 September 2023, the Department for Energy Security and Net Zero issued a change notice in accordance with BUS Regulation 13(4) to increase the BUS grant level for air source heat pumps and ground source heat pumps.

Acting on behalf of property owners, installers can apply for: 

  • £7,500 off the cost and installation of an air source heat pump
  • £7,500 off the cost and installation of a ground source heat pump, including water source heat pumps
