Do I need planning permission?
Find out what work needs planning permission and what doesn't.
You might need planning permission to:
- build something new
- extend a property
- build a conservatory
- put a dormer window into your roof
- put up a garage or shed
- change the use of a property
- carry out engineering or mining work
- carry out external alterations such as re-roofing or roof lights
Other permissions you might need
- Listed building consent, if you're altering or extending a listed building
- Conservation area consent, if you're demolishing a building or walls in a conservation area
- Advertisement consent, if you're putting up an advertisement
- Tree Preservation Order (TPO), if you're doing work to trees
Work that doesn't need planning permission
Some small building work might not need planning permission. This is known as permitted development. Examples include:
- small front porches
- some extensions or conservatories
- satellite dishes
- replacement windows and doors
- dormer windows at the rear of building
- detached garages and sheds
You don't have permitted development rights if you live in a conservation area. Even small changes or developments might need planning permission.
