Who handles building control for my Kent address?

Start with your district or borough council, not Kent County Council; Medway addresses use Medway Council. Your council may deliver building control through a partnership. Check your property's coverage before comparing it with a registered private approver, and request a current quote for the same drawings and scope.

Appointing a building control provider in Kent

Kent councils run building control through local partnerships such as STG Building Control and Kent Building Control Partnership, alongside private registered approvers.

Property you'll be working with in Kent

How to choose a building control provider in Kent

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.

  1. Decide between your local authority and a registered building control approver early.
  2. Confirm how many inspections are included and what triggers an extra charge.
  3. Ask how much notice they need for each inspection stage.
  4. Keep the completion certificate: you will need it when you sell.
  5. Check who notifies the council if you use a private approver.

Around £700 to £1,500 for a typical domestic extension on a full plans application.
