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.  Grants of £5000 are available for air source heat pumps (ASHPs) and biomass boilers, and grants of £6000 are available for ground source heat pumps (GSHPs). Grants are offered at a flat rate and do not vary by capacity of the installation, which must not exceed 45 kWth. The scheme opened for account creation on 11 April 2022 and opened to applications on 23 May 2022.

This guidance outlines Ofgem’s administration of the BUS. It is for property owners wishing to install a BUS funded heat pump or biomass boiler. This document was first published on 6 May 2022 as draft guidance for comment. We published an updated version on 21 July 2022 following feedback.
