How tall can a garden fence be in England without planning permission?

How tall can a garden fence be without planning permission?

In most cases a garden fence can be up to 2 m high, or 1 m high where it is next to a highway used by vehicles, without planning permission. Exceptions apply, so check with your council or the Planning Portal before you build. This page is a signpost, not planning or legal advice.

The rule comes from the General Permitted Development Order 2015 (Schedule 2, Part 2, Class A) on legislation.gov.uk, and the Planning Portal gives the same heights, measured from ground level. These are the rules for England, which is all we cover. The Planning Portal page does not mention flats, so if you live in one, ask your council.

What are the exceptions?

The Planning Portal says you need permission if any part of the site is a listed building or within its curtilage, or if the boundary adjoins a neighbouring listed building or its curtilage. You also need it if an Article 4 direction or a planning condition has removed the right to put up or alter fences, walls and gates.

A planning condition can remove the right, so ask the council. The Planning Portal also says that you might need permission to take down a fence in a conservation area, so ask the council about any conservation area rules that apply to you. Your council can tell you whether any of these apply to your address.

Is an acoustic fence treated differently?

We found no separate rule. The Planning Portal's fences page does not mention acoustic fences, so the same height limits appear to apply to an acoustic fence as to any other fence. Ask your council if you are unsure.

That matters because the benefit of a fence depends on breaking the line of sight to the road, and a 2 m limit can cap what a fence achieves. Our guide to acoustic fence height explains why, and why closing the ends of a fence can matter more than adding height. The wider evidence is in our guide to the best fence or wall for road noise.

What about the boundary and my neighbour?

Planning permission and boundary ownership are separate questions, so check who owns the boundary and speak to your neighbour before you start. GOV.UK guidance says the Party Wall etc. Act 1996 can cover a garden wall that stands on the land of two owners, but that timber fences are excluded. If you are unsure, a solicitor or surveyor can advise.

Does a taller fence need to be structurally sound?

The Planning Portal says fences, walls and gates do not need Building Regulations approval, but they must still be structurally sound and maintained. Wind load rises with height: one trade cost guide (Trade2Base, 14 June 2026) says going to 2.4 m or above roughly doubles wind loading and needs deeper foundations and heavier posts. We found no source that sets a height above which an engineer is required, so ask your installer how the posts and foundations are designed.

What we do not know

We read the legislation text for the height limits and the Planning Portal pages for the exceptions. The wording on flats, conservation areas and planning conditions comes from the Planning Portal rather than the legislation, and councils can set their own conditions. Rules also change. Scotland, Wales and Northern Ireland have their own rules, which this page does not cover.

What is a sensible next step?

Ask your council or check the Planning Portal for your address first. Our guide to acoustic fencing costs explains what moves the price. If you are weighing up whether a fence is worth building at all, the Fence Feasibility Check models whether a barrier at your address is likely to help, as a modelled estimate rather than a measurement.
