Free toolDo I need planning permission?
Answer a few questions about your extension, loft conversion, porch, garden room, fence or demolition. We'll tell you what England's rules say is likely — and what else your project will need.
How this works
It applies England's householder permitted development rules and the demolition rules to your answers. It is a guide, not a decision — your council can remove these rights in some areas (an "Article 4 direction").
Want certainty?
If your project should be permitted development, you can apply to your council for a Lawful Development Certificate. It isn't compulsory, but it is proof — useful when you sell the house or if a neighbour complains.
Official guidance: Planning Portal — common projects. Rules shown here apply to England only and are general information, not legal advice.
