Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, how many and what proportion of projects announced under the Social Housing Decarbonisation Fund involve the installation of ground source heat pumps.

Under the Social Housing Decarbonisation Fund (SHDF) main fund, Wave 1 has awarded around £179m of grant funding for delivery from 2022 into 2023. At the point of award, 7% of projects were expected to install ground source heat pumps (GSHPs), including shared ground loops (SGLs). Published SHDF Wave 1 Official Statistics will show which measures have been delivered.

Around £778m of grant funding was allocated to 107 projects under SHDF Wave 2.1 on 22 March 2023. At the point of award, 8% of successful projects intended to install GSHPs or SGLs.
