Permitted Development Rules for a Retaining Wall
Whether a retaining wall needs planning permission depends on its size and the extent of ground-level change. Small retaining walls (under 1m height of retained earth) are generally treated as engineering operations within the curtilage and may be PD. Larger retaining walls that significantly alter ground levels are likely to require a planning application.
Conditions
- 1Small retaining walls may be PD as engineering operations within the curtilage
- 2The height of a retaining wall is measured from the lower ground level, not the higher
- 3If the retaining wall also acts as a boundary wall, the combined height limit of 2m (or 1m near a highway) applies
- 4Must not cause drainage issues for neighbouring properties
Size and Dimension Limits
- No specific PD height for retaining walls; LPA interpretation varies
- If acting as a boundary: 2m maximum (1m adjacent to highway)
When Permitted Development Does Not Apply
- Significant changes to ground levels usually require planning permission
- Party wall agreements may apply if near a boundary
- Structural design is critical; poorly designed retaining walls can fail dangerously
- Drainage behind the wall (weep holes or land drains) is essential
What About Building Regulations?
Building regulations approval is not usually required
Building Regulations do not formally apply to garden retaining walls. However, structural engineering design is strongly recommended for walls retaining more than 600mm of earth. Failure of a retaining wall can cause injury or property damage, and the homeowner is liable.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Leeds building control or use an approved inspector.
How to Apply in Leeds
If you need planning permission for your retaining wall, you can apply through Leeds's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Leeds. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Moderate risk for large retaining walls that significantly alter ground levels. Enforcement can require removal or alteration of the wall. Failed retaining walls that cause damage to neighbouring properties create civil liability for the homeowner.
