Types of Building Control Applications

Full Plans Application – You submit detailed drawings and specifications for approval before work begins. This is common for larger projects and provides certainty that work will comply.
Building Notice – A simpler process with no need for pre-approved plans. Suitable for smaller projects but has more risk, as work is inspected as it progresses.
Regularisation Application – Used to get approval for unauthorised work that was done without Building Control approval.
