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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what recent estimate he has made of the number of (a) air source and (b) ground source heat pumps installed in households in Lewisham East constituency in each year since 2018.

The Microgeneration Certification Scheme Installations Database shows that between 01 January 2018 and 31 October 2022, eight air source heat pump and no ground source heat pump installations were registered in the Lewisham East constituency.

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