When you can start the work
You don't have to wait for the plans to be passed before you start work, however, having them passed gives you some protection against unnecessary costs.
After you have given us a Building Notice or sent us plans you can start work provided you contact us and arrange for a surveyor to inspect. Information may be requested to justify certain items (e.g. structural calculations for timber beams and steelwork).
If you proceed with the work without having notified us you may be asked to open the works up so that the Building Control surveyor can check whether it complies with the Regulations. Our Building Control surveyor will work closely with your contractor to ensure your project runs smoothly, on time and in compliance with the Building Regulations.
