What Is the Maximum Fence Height Without Planning Permission?
Quick Answer
2 metres (or 1 metre if fronting a highway)
Based on: Permitted development rights under the Town and Country Planning (General Permitted Development) Order (England)
The Rules
Under permitted development (PD) rights in England, you can erect or alter a fence, wall, or gate without planning permission provided:
- The height does not exceed 2 metres above ground level
- If adjacent to a highway used by vehicular traffic, the height must not exceed 1 metre
- The property is not a listed building (where Listed Building Consent may be needed)
When You Need Planning Permission
- Fence over 2m high (or over 1m next to a highway)
- Property in a conservation area (additional restrictions may apply)
- PD rights have been removed by condition on your property
- The fence is on or near a public right of way
What Counts as “Height”?
Height is measured from the natural ground level on the highest side to the top of the fence (including any trellis on top). If you add 600mm trellis to a 1.8m fence, the total is 2.4m — which would require planning permission.
Boundary Disputes
Even if planning permission is not required, you should check your title deeds for any restrictive covenants on fence heights. The Party Wall Act does not cover garden fences, but it is good practice to discuss plans with neighbours before building.
