Asked by:
Dr Simon Opher (Labour)

For Warm Homes: Social Housing Fund (WH:SHF) the Government publishes Official Statistics including WH:SHF Waves 1 and 2 measures installed, homes treated, carbon and bill savings. Statistics on WH:SHF Wave 3 and Warm Homes: Local Grant (WH:LG), summary business cases covering both schemes 2025/26-2027/28 and evaluation findings, will be published in due course.

There is a robust evaluation approach in place for the Boiler Upgrade Scheme (BUS). The Government will publish an Impact Assessment covering the BUS from 2025/26 through to 2029/30. An Impact Assessment for period 2022/23 to 2024/25 is already published. The Government publishes Official Statistics including BUS deployment volumes to date (Table 1.1) and Energy and Emissions Projections (EEP) containing the estimated emission savings generated by BUS installations.
