Uncertainty about permitted fence height and ownership
Fence Height Rules and Boundary Basics
Most fencing disputes come down to two questions: how high can it be, and whose fence is it? Both have clearer answers than people expect.
This is general guidance — always confirm with your local planning authority and your title deeds before committing.

Height under permitted development
As a general rule, a fence, wall or gate can be up to two metres high without planning permission, reducing to one metre where it adjoins a highway used by vehicles — which includes most front gardens.
Restrictions differ for listed buildings, conservation areas, and where a planning condition or covenant removes permitted development rights.
Working out ownership
Your title plan and any deed covenants are the authority. The widespread belief that the posts always face the owner's side is a convention, not a rule.
Where the boundary is genuinely shared, agreeing the specification and cost split in writing before work starts saves a great deal of difficulty.
Practical courtesies that avoid disputes
Keep the fence within your boundary, give notice before starting, and arrange access rather than assuming it. Building on your own side means you never depend on permission to maintain it.
For trellis or a height increase, check the total height including any addition.
Frequently asked questions
Can I add trellis on top of a two metre fence?
The total height including trellis is what counts, so that would generally exceed permitted development.
Do I need permission for a front garden fence?
Above one metre next to a road used by vehicles, generally yes.
Who maintains a shared boundary?
Whatever the deeds say; where they are silent, it is a matter for agreement between neighbours.
