Permitted Development Rules for a Fencing (Under 2 Metres)
Generally permitted under Part 2, Class A of the GPDO. Fences, walls, and gates up to 2m in height do not require planning permission, provided they are not adjacent to a highway used by vehicular traffic (where the limit is 1m).
Conditions
- 1Maximum height of 2m
- 2If adjacent to a highway used by vehicular traffic, maximum height is 1m
- 3Must not be erected in front of the principal elevation if it would exceed 1m (highway boundary)
- 4Replacement fencing to the same height is also PD
Size and Dimension Limits
- Height: 2m maximum (1m if adjacent to a highway used by vehicles)
When Permitted Development Does Not Apply
- Listed building consent may be needed if the fence affects the setting of a listed building
- In conservation areas, fencing is generally still PD but check for Article 4 directions
- High hedges are covered by separate legislation (Anti-social Behaviour Act 2003, Part 8)
- Boundary disputes are a civil matter, not a planning issue
What About Building Regulations?
Building regulations approval is not usually required
Building Regulations do not apply to garden fencing. There are no structural, thermal, or fire safety requirements for domestic fences under 2m.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Welwyn Hatfield building control or use an approved inspector.
How to Apply in Welwyn Hatfield

If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Welwyn Hatfield. 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?
Very low risk for fencing under 2m. Enforcement is only likely if the fence is on a highway boundary and exceeds 1m, or if there is an Article 4 direction. Boundary ownership disputes are a civil matter between neighbours.
