Who needs permission?
Central government's Planning Portal explains whether the work you want to do to your property is "permitted development" (in which case you don't need planning permission) or whether it is not permitted development (in which case you do need planning permission). There are useful sections on:
- About the planning system
- Planning permission
- Do you need permission?
- Change of use - whether planning permission is needed or not
- Your responsibilities
Information for householders
The Planning Portal gives detailed guidance on:
- Common projects
- Interactive house - guidance on many common householder projects
- Interactive terrace - guidance relating to flats, shops and basements as well as many common householder projects
- New guidelines for rear extensions
- Mini guides on: Loft conversions, Extensions, Conservatories, Outbuildings and Porches
What to do next
If you're completely sure your work is permitted development and that you don't need planning permission, you can start your building work. For peace of mind and proof that your building work is lawful you may choose to apply for a Lawful Development Certificate.
If your work does not qualify as permitted development then you must apply for planning permission before going ahead.
