Do I Need Planning Permission for Decking?
Usually NO
In most cases, NO â decking is usually permitted development if it is low (under 30cm high) and does not cover more than 50% of the garden.
Keep reading for the full rules.
Garden decking is generally permitted development under Class E of the GPDO 2015, but the key rule is height: if the deck (including any structure) is less than 30 centimetres above ground level, it is very likely to be PD. Higher platforms and raised decking may need planning permission.

When Do You Need Planning Permission?
Even if your project is usually permitted development, planning permission is required in these circumstances:
- âThe decking is more than 30cm above ground level.
- âThe decking is forward of the principal elevation.
- âThe decking (combined with other outbuildings) covers more than 50% of the garden.
- âYour property is a listed building.
What Happens If You Build Without Permission?
Raised decking that requires planning permission but does not have it can result in an enforcement notice requiring removal or modification.
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.
