The short answer
For most homes you do not need planning permission for a garden wall up to 1 metre high where it is next to a highway used by vehicles (or the footpath of one), or up to 2 metres high elsewhere — these are permitted development limits in England. You do need permission if the wall is taller than those limits, if your home is a listed building or forms a boundary with one, or if permitted development rights have been removed by an Article 4 direction or a planning condition; in a conservation area it is wise to check with the local planning authority first. Building regulations are separate and can apply to retaining walls or walls that support a structure.
Two questions decide a garden wall job: is it under the height limit, and is there anything special about the site? For most walls the answer is 'yes, no permission needed'. The exceptions below are the ones that matter.

- Elsewhereup to 2m — no permission

The height rules
In England, putting up a garden wall is permitted development — no planning permission — as long as it is no more than 1 metre high if it is next to a highway used by vehicles, or the footpath of such a highway, and no more than 2 metres high anywhere else. Height is measured from ground level. Go above those limits and you need to apply for planning permission. The same height test applies to fences and gates, so a mixed boundary is judged on its tallest point next to the relevant edge.
| Location | Height limit (no permission) |
|---|---|
| Next to a highway (or its footpath) | 1 metre |
| Elsewhere in the garden | 2 metres |
| Above either limit | Planning permission needed |
| Listed building or its boundary | Permission needed regardless |

The exceptions and building regulations
The height limits do not apply if your home is a listed building or the wall forms a boundary with a listed building or its curtilage — then you need permission whatever the height. They can also be removed by an Article 4 direction or a planning condition (common in conservation areas), so it is worth a quick check with the local planning authority before you build. Separately, building regulations are not usually triggered by a low freestanding wall, but can apply to a retaining wall or any wall that supports a structure — another reason to get a retaining job specified properly.

Frequently asked questions
Do I need planning permission for a garden wall?
Usually not, as long as it is no more than 1 metre high next to a highway used by vehicles (or its footpath), or no more than 2 metres high elsewhere. Above those heights, by a listed building, or where permitted development rights have been removed, you do need permission.
How high can a garden wall be without permission?
Up to 1 metre next to a highway and up to 2 metres elsewhere, measured from ground level. These are permitted development limits in England — listed buildings and Article 4 areas are exceptions.
Do building regulations apply to a garden wall?
Not usually for a low freestanding wall, but they can apply to a retaining wall or a wall that supports a structure. Confirm your specific case with your local authority.
