What is the Boiler Upgrade Scheme and How Does it Work?

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.

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

  • £5000 off the cost and installation of an air source heat pump
  • £5000 off the cost and installation of a biomass boiler (please note the grant will only cover biomass boilers in rural locations, in properties that are not connected to the gas grid, and with an emissions certificate showing that polluting emissions are kept to a minimum. Biomass boilers in self-build properties are not eligible under the scheme).
  • £6000 off the cost and installation of a ground source heat pump, including water source heat pumps

You cannot get a grant for a hybrid heat pump system (for example a combination of gas boiler and air source heat pump).

£450 million of grant funding is available over three years from 2022 to 2025.

Who can apply?

It’s open to homeowners, as well as owners of small business properties, in England and Wales only.

To apply, you’ll need to:

  • Own your property (this can be a home or a small business property).
  • Have a property with an installation capacity up to 45kWth (this covers most homes).
  • Have a valid Energy Performance Certificate (EPC). Your EPC must not have any outstanding recommendations for loft or cavity wall insulation (unless you have an insulation exemption).

How does the process work?

  1. Simply press apply now below, complete a few details and we will put you in contact with MSC certified installers in your area.
  2. If you are happy to proceed, the installer will then apply for the grant on your behalf.
  3. You will need to confirm that the installer is acting on your behalf when Ofgem contact you.

The MCS quality assurance scheme ensures that installers are competent and the products they use meet the correct standards.
