Apply for regularisation

If you completed works without our approval, you need to apply for retrospective building control approval through a process called regularisation.

What happens when you apply for regularisation

  • After you apply for regularisation our staff will inspect the work.
  • This may mean exposing parts of the construction.
  • If the work is found to be deficient in any way, you must do additional work to make it comply with regulations.

You need to pay a fee to us when you apply for regularisation. View our building control fees.

Apply for regularisation

After you complete your application:

  • We will send you an email confirmation with your reference number, after we receive your application.
  • You’ll be given the name and contact details of your site inspector while we process your application.
