When Permitted Development Does Not Apply

- Conservation areas may have additional requirements for wall materials and design
- Retaining walls that change ground levels significantly may require a separate planning assessment
- Party wall agreements may apply if building on or near a boundary
What About Building Regulations?
Building regulations approval is not usually required
Building Regulations do not normally apply to garden walls. However, walls over a certain height (typically 1.8m to 2m) may benefit from structural engineering design to ensure stability, particularly in clay soils or exposed locations.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Spelthorne building control or use an approved inspector.
How to Apply in Spelthorne
If you need planning permission for your garden walls, you can apply through Spelthorne'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 Spelthorne. 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?
Low risk for walls under 2m. Enforcement applies to walls over 2m or over 1m adjacent to a highway. Poorly constructed walls that collapse and cause damage are a separate liability issue.
