Do I Need Planning Permission for a Pergola?
Usually NO
In most cases, NO — a pergola is usually permitted development as an outbuilding, provided it is open-sided and meets the height limits.
Keep reading for the full rules.
A pergola — whether a simple open-sided structure or a more substantial garden feature — generally does not need planning permission. It is treated as an outbuilding under Class E of the GPDO 2015, provided it meets the standard outbuilding size and height rules.
Permitted Development Rules by Region
Permitted Development Rules — England
- ✓A pergola is treated as an outbuilding and is permitted development if it meets Class E criteria.
- ✓Must be in the rear or side garden — not forward of the principal elevation.
- ✓If within 2 metres of the boundary, maximum height is 2.5 metres.
- ✓If more than 2 metres from the boundary: 4 metres (dual-pitched) or 3 metres (other roofs).
- ✓Must not cover more than 50% of the original garden.
- ✓Must not be used as a dwelling.

Size & Position Limits (England)
| Requirement | Limit / Rule |
|---|---|
| Max height (within 2m of boundary) | 2.5 metres |
| Max height (>2m from boundary) | 3–4 metres depending on roof type |
| Max garden coverage | 50% of original garden |

When Do You Need Planning Permission?
Even if your project is usually permitted development, planning permission is required in these circumstances:
- ✗The pergola exceeds the height limits.
- ✗It is forward of the principal elevation.
- ✗Combined with other outbuildings, it covers more than 50% of the garden.
- ✗Your property is listed.
What Happens If You Build Without Permission?
If a pergola is built without required permission, an enforcement notice 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.
