Evaluation of the Boiler Upgrade Scheme
Findings from the evaluation of the Boiler Upgrade Scheme.
The Boiler Upgrade Scheme (BUS) supports the decarbonisation of heating in domestic properties by incentivising the deployment of low carbon heating (LCH) systems.
The original duration of the BUS (2022 to 2025) is subject to an evaluation.
These reports and data tables provide evaluation findings, based on research conducted with:
- property owners who had a low carbon heating system installed under the scheme
- BUS registered installers
- other groups
The reports also draw on wider evaluation analysis.
