Do You Need Planning Permission for a Pergola in the UK?
Most UK pergolas are Permitted Development, but size, position, and your property type all matter. Here's what you need to know before you build.
The short answer: most pergolas in England and Wales don’t need planning permission — they fall under Permitted Development rights. But the rules hinge on specifics, and getting them wrong is expensive.
Permitted Development rules for pergolas
Under Class E of Schedule 2 to the Town and Country Planning (General Permitted Development) (England) Order 2015, garden structures are Permitted Development if they meet all of the following:
- Height — no more than 2.5 m within 2 m of a boundary; up to 3.5 m further away (4 m for a dual-pitched roof)
- Position — located in the curtilage of the dwelling, behind the rear wall of the original house
- Coverage — the structure, together with any existing outbuildings, must not cover more than 50% of the garden
If all three conditions are met, you don’t need to apply for planning permission.
When you do need permission
The Permitted Development rules don’t apply if:
- Your property is a listed building — any works require Listed Building Consent
- You’re in a conservation area, National Park, or Area of Outstanding Natural Beauty — the same rules apply on paper, but local councils often have Article 4 directions that remove PD rights
- The pergola is at the front or side of the house (not rear)
- Your pergola is attached to the house and could be considered an extension
Attached pergolas vs freestanding
An attached pergola that is structurally connected to the house is treated differently — it may be assessed as a house extension under Class A rather than a garden structure under Class E. The height rules are stricter and the 50% coverage calculation works differently.
Getting certainty
If you’re unsure, apply for a Lawful Development Certificate (LDC) from your local planning authority. It costs around £206 in England (as of 2026) and gives you legal confirmation that no planning permission is needed. It’s not mandatory, but it protects you if you ever sell.
