Building control

Information on building regulations, how to apply for building regulations approval, and CNC Building Control

What are building regulations?

Most building projects are required to comply with the building regulations. This includes internal alterations, extensions and new builds. It applies both to commercial projects and individual homes. Building control is there to ensure:

  • buildings are safe, dry and warm
  • buildings are energy efficient
  • people can easily access the facilities in the building, and their escape is not compromised in the event of fire
  • the health and safety of people in and around all types of buildings are considered

Please note: Building control is totally separate to planning. You’ll probably still have to apply for building control regulations, even if your project does not require planning permission.

Building regulations approval

For most types of work you’ll need to have building regulations approval, as well as obtaining planning permission. You’ll need to make separate applications for both.

To find out more about the difference between building regulations approval and planning permission, please visit the Planning Portal website.

How to apply

Building control services are now dealt with by CNC Building Control. To apply for building regulations approval please visit the CNC Building Control website.

Your project will need to be inspected at various stages. At commencement, please contact CNC, and they'll arrange an initial visit. All visits will be on next-day regime if booked before 4pm. At the first visit, the inspector will inform you when they need to come, and what they need to see. 

Once the work has been completed and signed off as satisfactory, a completion certificate will be issued.

Please note, the certificate is an important document you must keep. It will be required by buyers if you ever decide to sell your house. And you may be charged for a duplicate copy to be produced.

To apply for planning permission, please visit our make a planning application page.
