Unauthorised building work

Work which has not followed building regulations may be unauthorised.

You can report building work which you think has been done without approval by:

Retrospective building control

Work that has been done without getting building regulations approval is unauthorised and can cause problems when you try and sell a property. You will need building regulations approval retrospectively by applying for a regularisation certificate.

It is only possible to apply for a regularisation certificate for work completed after 11 November 1985. Once we have received your application we may need to inspect the work before issuing a regularisation certificate.
