Boiler Upgrade Scheme
The Boiler Upgrade Scheme (or ‘BUS’ for short) gives eligible homes a £7,500 grant to help replace their old gas or oil boiler with a clean energy heat pump.
As part of our hassle-free switch, we’ll apply for the grant on your behalf and deduct it from your quote when you switch.
