Do You Need Planning Permission for a Pergola?.

Quick answer

If your pergola is under 2.5m high (within 2m of a boundary), sits behind the rear of the house, does not take up more than half the garden, and you are not in a conservation area or in a listed building, you almost certainly do not need planning permission.

When you should check first

You should contact your local planning authority before installation if: the pergola is taller than 2.5m near a boundary; your home is listed; you live in a conservation area, National Park or AONB; or you are attaching a large pergola to the rear of the house that could be classified as an extension.

What about Building Regulations?

Most open pergolas do not need Building Regulations approval. However, if the structure is large, has electrical work for lighting or motorisation, or is fixed to the house in a way that affects the building, you may need a Part P electrical certificate from your installer and, in some cases, structural sign-off.

How tall can a pergola be without planning permission?

Under Permitted Development in England, a pergola can be up to 2.5m high if within 2m of any boundary, or up to 3m (4m for a dual-pitched roof) elsewhere in the garden, providing it sits behind the principal elevation of the house.

Do I need planning permission for a pergola attached to my house?

A pergola attached to the house is treated as an extension under Permitted Development. It must not extend beyond the rear wall by more than 3m (detached houses) or 4m, must not exceed 4m in height, and the eaves must not exceed 3m if within 2m of a boundary. Check with your local planning authority for your specific case.

Are there different rules in conservation areas?

Yes. Permitted Development rights are often restricted in conservation areas, National Parks, Areas of Outstanding Natural Beauty and World Heritage Sites. You may need full planning permission even for a modest pergola. Always check with your council before proceeding.
