Gates, fences, walls or other means of enclosure
GPDO 2015, Schedule 2, Part 2, Class A
Fences, walls, and gates are covered by Part 2, Class A of the GPDO. The main consideration is height: up to 1 metre next to a highway, up to 2 metres elsewhere.
Key dimension limits
These are the maximum GPDO limits for a detached house with no constraints. Your actual limits depend on your property type, location, and any planning restrictions.

Boundary treatments rarely need professional services beyond a competent builder or fencing contractor.
This project is unlikely to need specialist professional services beyond a competent builder.
This type of project does not typically require architectural services.
This guidance is based on a typical semi-detached house with no special constraints. Listed buildings, conservation areas, and attached properties may require additional professional input.

Get personalised guidanceConservation 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.
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 (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.
