Retrospective approval of building works

If you have carried out work without first receiving building regulations approval then you can apply for retrospective approval. This process is called regularisation.

This applies to all works carried out after 11th November 1985.

If you do not gain approval then you may have problems re-mortgaging or selling the property. There may also be health and safety problems.  

How to apply 

You should contact Swansea Building Control on 01792 635636 or email bcon@swansea.gov.uk. You can find out how to make a payment on our Fees page. The fee will be the standard amount for the work plus an extra 50%.

You should provide two copies of plans showing the work before and after with full constructional details, along with a regularisation application form and the full fee.

What happens next

Once your application is received, a surveyor will contact you to visit the premises and check what has been done. If remedial work is necessary this will be highlighted and once put right, a regularisation certificate will be issued.

Planning permission

Remember you may also need planning permission for the work. Application forms and information are available on our Planning pages.
