Garden wall planning permission in England: what to check
Understand height limits, road-facing walls and why a simple garden wall can still need checks.
Applies to: England; local restrictions, listed properties and the exact site can change the answer.
Last checked: 16 October 2026
Key points
• England's general planning rules typically distinguish walls next to highways from those elsewhere.
• Planning Portal gives common limits of 1 metre next to a vehicle highway and 2 metres elsewhere, subject to important conditions.
• Even where building regulation approval is not required for a free-standing garden wall, it must be safe.

Check the specific location
Planning Portal sets out common permitted-development conditions: a new or altered wall generally must not exceed 1 metre next to a highway used by vehicles or its footpath, or 2 metres elsewhere. A listed building, planning condition, Article 4 direction or other restriction can change what is permitted.
Before work starts
• Measure height from the relevant ground level and identify whether the boundary meets a highway.
• Check with the local planning authority if there is any restriction or uncertainty.
• Establish whose land and wall it is before removal or rebuilding.
• Consider party-wall notices where a shared wall or affected neighbouring excavation falls within the Act.
• Have an appropriate person check wall stability, footing and wind exposure.
Planning is not the same as structural safety
A wall can fall within permitted development and still be dangerously thin, poorly supported or cracked. Seek competent advice for tall, exposed, retaining or already damaged walls.
