Do I need building regulations?

You must check if you need approval before you construct or change buildings in certain ways. Building regulations approval is different from planning permission.

This may include:

  • installing a bathroom that will involve plumbing
  • putting in a fixed air-conditioning system
  • replacing windows and doors
  • replacing roof coverings on pitched and flat roofs
  • installing or replacing a heating system
  • erection or extension of a building
  • installation or extension of a service or fitting which is controlled under the regulations
  • an alteration project involving work which will temporarily or permanently affect the ongoing compliance of the building, service or fitting with the requirements relating to structure, fire, or access to and use of buildings
  • insertion of insulation into a cavity wall
  • underpinning of the foundations of a building
  • work affecting the thermal elements, energy status or energy performance of a building.

You do not need to get approval yourself if you use someone registered with a competent person scheme.
