Do I need building regulations approval

Building regulations approval is required for many home improvements as well as work to commercial and other non-domestic properties. This includes:

  • new or extension of a building (including loft conversions)
  • change of use of all or part of a building (eg conversion of a shop into a dwelling, conversion of a house into flats and conversion of a garage into a room)
  • alterations which effect the structure, fire safety and access
  • new or changes to washing and sanitary facilities, hot water cylinders, drainage
  • electrical installations in dwellings
  • replacement windows and external doors
  • new fuel burning appliances
  • cavity wall insulation
  • underpinning
  • See LABC Your project (external website): for detailed advice on when you need building regulation approval.

If in doubt, please contact us.

Local Authority Building Control (LABC) represents all local authority building control teams in England and Wales. It provides advice for developers, homeowners and building control officers.

Our building control service is here to see that building work complies with the building regulations and to enforce standards.

Exempt building work

Some minor works are exempt from building regulations. Examples include:

  • conservatories
  • porches
  • carports, covered yards
  • new or extensions to small detached buildings and which contain no sleeping accommodation

If you think your planned work is exempt, check with us first before you start the work.

Planning permission

Remember to check whether your building project also requires planning permission.
