Details

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 (2022-2025) is subject to an evaluation.

These reports and data tables provide interim evaluation findings, based on research conducted with property owners who had a LCH system installed prior to the heat pump grant uplift, as well as research with registered installers.

This is the first publication of the BUS evaluation, with more to follow in 2025 and 2026.

Topics covered in these outputs include:

  • property owners鈥� experiences of participating in the BUS
  • why property owners joined the Scheme
  • property owners鈥� satisfaction with the Scheme and their installations
  • installers鈥� experiences of joining the BUS
  • installers鈥� experiences of submitting grant applications
