Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, how many domestic households in Ceredigion depend on (a) air source and (b) ground source heat pumps for their heating.

The Microgeneration Certification Scheme Installations Database shows that as of 31 December 2022, (a) 436 air source heat pumps and (b) 53 ground/water source heat pumps were installed in domestic properties in Ceredigion.

The database does not include all heat pump installations, for example, those installed without Government funding support, such as in new buildings, which are not typically recorded in the Microgeneration Certification Scheme Installations Database.
