Installing a ground source heat pump system does not usually need planning permission. If you live in a listed building or a conservation area, however, you should contact your council to check on local policy.

Where this is installed as part of works to provide a new or replace an existing heating and hot water system the building regulations energy efficiency requirements apply.

Other technical requirements would apply too if, for instance, the works included in the electrical or drainage work.

It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either the Microgeneration Certification Scheme or the relevant Competent Person Schemes.

For detached houses all work must adhere to the building regulations set out in Approved Document L: Volume 1.  

Heat pumps transfer heat into a building to provide space heating and, in some cases, to pre-heat domestic hot water.
