Executive Summary

The Boiler Upgrade Scheme (BUS) launched on 23 May 2022 to support the decarbonisation of heat in buildings. It provides upfront capital grants towards the cost of installing approved heat pumps and biomass boilers in homes and small non-domestic buildings in England and Wales. Decarbonising the way we heat our homes and businesses is essential to reach net zero carbon emissions and the BUS has an important role to play in achieving this.

As scheme administrator, we ensure the scheme is operated efficiently, including managing applications made by installers, issuing vouchers, making payments, and reporting on scheme activity. Additionally, our audit and compliance programme monitors compliance with the scheme rules, making sure that grants are only paid to those eligible to receive them.
