Boiler Upgrade Scheme

The government is providing grants to encourage property owners to install low carbon heating systems such as heat pumps, through the Boiler Upgrade Scheme (BUS). These grants can help property owners overcome the upfront cost of low carbon heating technologies. We will be posting more information on the BUS in the coming weeks, but here are the main things you need to know…

The scheme is open to domestic and small non-domestic properties in England and Wales. It launched for new applications on the 23rd May and runs until 2025.

The grants are not available for new build properties, however the good news is that self-built homes are exempt from this.

The grants available are:

  • £5,000 off the cost and installation of an air source heat pump
  • £5,000 off the cost and installation of a biomass boiler*
  • £6,000 off the cost and installation of a ground source heat pump (including water source heat pumps and those on shared ground loops)

You can get one grant per property.

*Biomass boiler grant does NOT apply to self builders.

The scheme is open to domestic and small non-domestic properties with:

  • an installation capacity up to 45kWth (this covers most homes)
  • a current energy performance certificate (EPC), with no outstanding recommendations for loft or cavity wall insulation
  • Crucially, the grant is not available for new build properties apart from certain self-builds.

To be eligible, a self-build must have:

  • been built mainly using the labour or resources of the first owner
  • not been owned by a business or organisation

You will need to provide proof to your installer that your property is a self-build, for example a copy of the title deeds.

Hybrid heat pump systems, for example a combination of a gas boiler and air source heat pump, are not eligible, and the new heating system must:

  • have been commissioned (that is, installed and fully checked by your installer) on or after 1 April 2022
  • be capable of meeting the full space heating and hot water requirements of your property
  • replace an existing fossil fuel heating system (such as oil, gas or electric)
  • meet certain technical standards, such as minimum efficiency requirements (your installer can advise you on these)

You cannot get funding for the replacement of existing low carbon heating systems.
