1. When you need approval

You must check if you need approval before you construct or change buildings in certain ways.

You don’t need to get approval yourself if you use someone registered with a competent person scheme.

Building regulations approval is different from planning permission. You might need both.

Work covered by building regulations

The Building Regulations 2010 cover the construction and extension of buildings.

You might also need building regulations approval for many alteration projects, including if you plan to:

  • replace fuse boxes and connected electrics
  • install a bathroom that will involve plumbing
  • change electrics near a bath or shower
  • put in a fixed air-conditioning system
  • replace windows and doors
  • replace roof coverings on pitched and flat roofs
  • install or replace a heating system
  • add extra radiators to a heating system

Check with a building control body if you can’t decide if you need approval.

Penalties and problems

The person doing the work could be prosecuted and fined if they don’t comply with building regulations.

Your local authority could make you pay for faulty work to be fixed.
