If you are new to the Building Regulations, our section on planning permission and the Building Regulations is a good place to start. It explains how the two regimes work and advises you on your responsibilities. If you are looking for more detailed information on the building control regime, we have a large section on the site dedicated to the subject. The Planning Portal is also the home of the Approved Documents on the web. You can download the Approved Documents and associated guidance from here.
