Boiler Upgrade Scheme

Boiler Upgrade Scheme

The Boiler Upgrade Scheme (BUS) came into effect on 1st April 2022, replacing the Renewable Heat Incentive (RHI).

This government scheme provides grants of up to £6000 for heat pump installations on existing domestic and small non-domestic properties. New builds are exempt, unless it is a self-build.

The funding is not available for the replacement of existing low carbon heating systems. Only properties which are fully replacing existing fossil fuel systems (such as oil, gas or direct electric) will be eligible for the scheme.

If eligible, the scheme allows for:

  • £5,000 off the cost and installation of an air source heat pump
  • £6,000 off the cost and installation of a ground source heat pump

You may be eligible if you:

  • live in England or Wales
  • own the property (whether this is a domestic or a small non-domestic property)

The property will need to have:

  • an installation capacity up to 45kWth (this covers most homes)
  • a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation (unless there’s an insulation exemption)
