What About Building Regulations?
Building regulations approval is not usually required
Building Regulations do not apply to domestic fencing regardless of height. However, very tall fences may need structural engineering input to ensure stability, particularly in exposed or windy locations.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact King's Lynn and West Norfolk building control or use an approved inspector.

What Happens If I Build Without Permission?
