Boiler Upgrade Scheme (BUS)
Support to help homeowners upgrade to low-carbon heating systems and reduce reliance on fossil fuels.
The Boiler Upgrade Scheme helps eligible households replace older heating systems with modern, energy-efficient alternatives such as heat pumps, installed by certified professionals across the UK.
What is the Boiler Upgrade Scheme?
The Boiler Upgrade Scheme (BUS) is a government-backed initiative designed to support the transition to low-carbon heating in homes across England and Wales.
The scheme provides financial support towards the cost of installing renewable heating systems, helping households move away from traditional fossil-fuel boilers and reduce long-term energy use.
Funding is applied as part of the installation process and is typically handled by an approved installer.
