Building control approver in Wales
13 providers offering building control approver in or across Wales, including national firms. The rules in Wales differ from England’s, so see the notes below.
The rules in Wales
You can choose council building control or a registered building control approver in Wales too. The Building Safety Regulator keeps a separate public register for Wales, so check that an approver is on it. New work on higher-risk buildings in Wales must be overseen by the local authority.
