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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate he has made of the levels of ancillary costs associated with installing heat-pumps in homes including (a) initial surveys, (b) planning permission applications and (c) noise surveys.

Most heat pump installations do not require planning permission, and compliance with noise regulations is typically covered as part of a heat pump suitability survey and design work carried out during the installation process.

BEIS-commissioned research (https://www.gov.uk/government/publications/cost-of-installing-heating-measures-in-domestic-properties) estimates that the average cost for a suitability survey and design for a typical 3-bedroom house is around £400.
