Appointing a building control provider in Surrey
Surrey councils offer building control through local services and partnerships, and private registered approvers are popular with builders on larger homes.
Property you'll be working with in Surrey

How to choose a building control provider in Surrey
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.
