Thinking of putting up a taller fence? Here are the rules for England, in plain words. Wales and Scotland are similar but not identical, so check locally if you're outside England.
The short answer
- Up to 2m high: you can usually put up a garden fence, wall or gate without planning permission.
- Up to 1m high: if it's next to a road used by vehicles, or the footpath beside that road.
- Anything taller usually needs planning permission.
A standard 6ft fence (1.8m) sits comfortably under the 2m limit, which is why it's the most popular height.
Does trellis on top count?
Yes. The height is the whole thing: fence plus trellis. A 1.8m fence with 300mm of trellis on top is 2.1m, which is over the limit.
When you need to check first
- New-build estates: many have open-plan front gardens, or planning conditions and covenants in the deeds that limit fences. Check your deeds before you build.
- Listed buildings and conservation areas: extra rules can apply. Ask your council.
- Sloping gardens: where the ground slopes or is higher on one side, check with your council how the height is measured for your fence.
Be a good neighbour
Even when you don't need permission, tell your neighbour before a new fence goes up, especially on a shared boundary. Not sure whose fence it is? Read which fence is mine?
Picking the height
- 6ft (1.8m): full privacy for back gardens
- 5ft (1.5m): privacy with a bit more light
- 4ft (1.2m): dividing fences and front gardens back from the road
- Under 1m: front boundaries next to the road

This is general guidance, not legal advice. If in doubt, check with your local council's planning team.
