The Boiler Upgrade Scheme is a Government grant scheme designed to help reduce the initial cost of installing renewable heating technologies in your home.


£450 million of funding has been made available over three years from 2022 to 2025.

The scheme was introduced to help the UK reach its target of Net Zero by 2050. The grants are available for both homes and non-domestic buildings in England and Wales.

To qualify for the BUS grant scheme, the work must be carried out by an MCS accredited installation company.
