Do I Need Planning Permission for a Shed?
Usually NO
In most cases, NO — a shed is usually permitted development as an outbuilding, provided it is within the size and height limits.
Keep reading for the full rules.
The vast majority of garden sheds do not require planning permission. Sheds are classified as outbuildings under Class E of the GPDO 2015. As long as your shed is within the size and height limits, is in the rear or side garden, and is not used as a dwelling, you can build it without permission.

What Happens If You Build Without Permission?
The council has 4 years to take enforcement action for unauthorised outbuildings. If your shed is unlawfully built, the council can require its removal.
Enforcement notices: Your council can issue an enforcement notice requiring you to stop the work, remove it, or restore the land to its original condition. You have a right of appeal against an enforcement notice.
Retrospective applications: If you have already carried out work that required planning permission, you can submit a retrospective planning application. If approved, this regularises the work. If refused, you may be required to remove it.
Time limits: For dwelling houses, the council generally has 4 years to take enforcement action for most types of work. For breaches of planning conditions, the time limit is 10 years. There is no time limit for listed building enforcement.
