Find out if you need planning permission

We offer a free online service to check whether your works will need planning permission. You simply need to enter your address and answer some questions about what works you want to do. The service will tell you whether those works need planning permission and will advise you on what to do next.

This service information is provided for guidance only and does not represent a planning decision or legal advice. We always recommend applying for a Lawful Development Certificate before carrying out permitted development works to ensure that the works are lawful.
