If you’re planning to build or modify a boundary wall around your property, it’s essential to understand the planning rules. Getting it wrong can lead to enforcement notices and costly alterations. So, just how high can you build a wall without needing planning permission in the UK?
The General Rule
In most cases, you can build or alter a wall without planning permission if it meets the following criteria:
- It does not exceed 2 metres in height (measured from ground level).
- If the wall is next to a highway used by vehicles or a footpath of such a highway, it must not exceed 1 metre in height.
- You are not increasing the height of an existing wall that already exceeds the above limits.
Note: Height is always measured from the natural ground level on your side of the wall.
Situations That Require Planning Permission
You’ll likely need to apply for planning permission if:
- The wall will be over 2 metres high, or over 1 metre if adjacent to a highway.
- You plan to increase the height of an existing wall beyond these limits.
- The property is a listed building or the wall forms a boundary with a neighbouring listed building or its curtilage.
- The property is in a conservation area and you wish to take down or significantly alter a wall.
- Planning rights have been removed by an Article 4 Direction or a condition attached to a previous planning permission.

What About Hedges?
Unlike fences and walls, hedges typically do not require planning permission. However:
- Planning conditions or covenants may restrict hedge planting—especially on “open plan” estates.
- If a hedge blocks visibility for drivers or breaches other restrictions, consent may still be required.
Other Considerations
Even when planning permission isn’t required, it’s worth checking the following:
- Party Wall Act: If your wall sits on or near a shared boundary, the Party Wall Act may apply, requiring agreement with neighbours.
- Materials and appearance: Some councils regulate the look and materials used, especially in design-sensitive areas.
- Neighbour relations: Very tall or dominant walls can create disputes. It’s always a good idea to inform or consult neighbours beforehand.
Summary: Wall Height Limits Without Planning Permission
| Location | Max Height Without Permission |
|---|---|
| Anywhere on your property | 2 metres |
| Next to a road or footpath | 1 metre |
If in doubt, contact your local planning department before building. Regulations can vary between councils and specific sites.
