How high can a fence be without planning permission?

Up to 1 metre if adjacent to a highway used by vehicles. Up to 2 metres elsewhere. These are the GPDO maximums.

Do I need planning permission for a garden wall?

Not if the wall is under 2 metres high (or 1 metre adjacent to a highway). Higher walls, or walls in areas with Article 4 Directions, need planning permission.

How much does fencing cost?

Boundary treatment costs in London typically range between £1,000 and £5,000, depending on length and materials. Timber fencing is cheapest, brick walls and metal railings cost significantly more.

Can I replace an existing fence with a taller one?

Yes, provided the replacement stays within the PD height limits (1m by highway, 2m elsewhere). The previous height is not relevant — it's the new height that matters.

Conservation Areas & Listed Buildings

In conservation areas, the same height rules apply, but you should consider materials that are sympathetic to the area character. Some Article 4 Directions restrict boundary treatments.

Conservation areas

Properties in conservation areas often have reduced permitted development rights. Some project types (like side extensions) lose PD rights entirely. An Article 4 Direction can remove additional PD rights.

Listed buildings

Listed buildings (Grade I, II*, or II) have no permitted development rights at all. Any external alteration requires Listed Building Consent in addition to any planning permission. An architect experienced in heritage work is essential.

Check if your property is in a conservation area or has other planning constraints.
