Do you need planning permission? Check before you build.
Tell us the project, your home and your postcode. We check your area against official conservation area and Article 4 data, apply the permitted development rules, and tell you in plain words whether you're likely to need permission, plus building regs and party wall notes.

Good to know
- Flats have no permitted development rights. Almost any outside change to a flat or maisonette needs planning permission.
- Planning and building regs are different. Most extensions and lofts need building regulations even when planning permission isn't needed.
- Conservation areas narrow the rules. Side extensions, dormers and some cladding usually need permission there.
- Want certainty? A Lawful Development Certificate from your council confirms a project is permitted development.
Guides by project: extensions, lofts, garden rooms, porches, fences, driveways and more.
