How to choose a building control provider
Every extension, conversion, structural opening and rewire needs building control approval, either through your council or a registered building control approver. Arrange it before work starts.
- Decide between your local authority and a registered building control approver early.
- Confirm how many inspections are included and what triggers an extra charge.
- Ask how much notice they need for each inspection stage.
- Keep the completion certificate: you will need it when you sell.
- Check who notifies the council if you use a private approver.
