Approved inspectors' building control service
When you use an approved inspector, they will take responsibility for checking the plans and inspection of your building work. The procedure requires you and the approved inspector jointly to notify your local authority of your intended building work on what is called an 'initial notice'.
The approved inspector will tell you what plans and information they need to check that the proposed work will comply with the Building Regulations.
If you ask, the approved inspector will, once satisfied, issue a plans certificate which will confirm that the plans of your proposed building work show compliance with the Building Regulations. When the work is complete the approved inspector should issue a final certificate to the local authority to say that the work referred to in the initial notice is complete and that the inspector has carried out their inspections. If the approved inspector is not satisfied that the work complies, then they cannot give the final certificate.
