Do You Need Planning Permission for a Fence? (UK Height Rules)
UK fence planning rules: the 2m height limit, the 1m limit next to a road, listed buildings and conservation areas, replacing an existing fence, and the boundary disputes to avoid.

Quick answer
A fence, wall or gate doesn't need planning permission in the UK if it's no more than 2m high, or no more than 1m high where it's next to a highway, including the footpath. Fences at listed buildings always need permission, and some conservation areas remove the right. Replacing an existing fence at the same height or lower never needs permission. Trellis counts towards the height.
Do You Need Planning Permission for a Fence? (UK Height Rules)
Fences are low on the list of things people expect to need planning permission for, and mostly they're right. The rules are short, but the one about roads catches people, and listed buildings catch everyone.
The two height limits
Fences, walls and gates are permitted development in England and Wales if:
- the fence is no more than 2m high, or
- no more than 1m high where it's next to a highway, which includes the footpath beside a road.
Height is measured from the ground level on the side the fence stands on. If the garden is higher than the pavement, the fence can appear much taller from the street and still be lawful, though it's worth being neighbourly about it.
Trellis counts. It's part of the fence for height purposes. A 1.8m panel with 30cm of trellis on top is a 2.1m fence and needs permission. Climbing plants don't count; the structure they climb does.
Where you need permission anyway
- Listed buildings. Any fence, wall or gate at a listed building needs planning permission, and the work may need listed building consent too.
- Conservation areas. Permitted development usually still applies, but councils can and do use Article 4 directions to remove it for front boundaries in particular. Check the council's planning portal.
- Removed rights. Some newer estates have had permitted development rights for boundary treatments removed by a condition on the original permission, usually to keep open-plan front gardens open.
- Higher than the limits. Apply for a householder planning permission. Councils are generally relaxed about rear fences and strict about anything that blocks visibility at a junction or driveway.

You never need permission to replace a fence with one of the same height or lower, as long as the existing fence was lawful. If you've been meaning to go higher, this is the moment the limits apply.
Walls and gates
The same limits apply to walls and gates. Gates next to a highway are limited to 1m like fences, which is why most front gates are low. A driveway gate taller than 1m needs permission, and if it opens onto the road the highways authority will want it to open inwards.

Planning permission doesn't settle who owns the fence or where the boundary runs. Before you spend money:
- Check the title plan at the Land Registry. T marks, where they exist, show which side is responsible.
- Talk to the neighbour. Most disputes come from a surprise, not from the fence itself.
- Build on your side of the line, with the posts on your land, so there's no argument later.
Check your property
The planning checker will tell you quickly whether your home is on designated land, and the local authority finder shows which council to ask about Article 4 directions. If the fence is part of a bigger front-garden project like a new driveway or a porch, it's simpler to deal with it all in one application.
Frequently asked questions
How high can a garden fence be without planning permission?
2m, measured from the ground on the side where it stands. Next to a highway, including the pavement, the limit drops to 1m. Trellis on top counts as part of the fence, so a 1.8m fence with 30cm of trellis is a 2.1m fence and needs permission.
Can I put up a 6ft fence in my front garden?
Only if it's not next to the road. The 1m limit applies to any fence, wall or gate adjacent to a highway used by vehicles, including the footpath beside it. A front boundary that runs along the pavement is limited to 1m; a side boundary in the front garden that doesn't adjoin the road can go to 2m.
Do I need permission to replace a fence?
No, provided the new fence is no higher than the one it replaces and the old one was lawful. If you take the chance to go higher, the normal limits apply. In a conservation area, check first: some councils have removed the right to replace boundary treatments without permission.
Whose fence is it?
There's no reliable rule of thumb. The deeds or the Land Registry title plan sometimes show ownership with a T mark; often they say nothing. If it matters, check the title before you start, and talk to the neighbour before you build. Most fence disputes are about the conversation that didn't happen, not the fence.
