Hedge Law UK: Your Rights & Responsibilities for Boundary Hedges

Hedges and neighbours do not always mix. From overhanging branches to a Leylandii that has blocked out the sun, boundary hedges are one of the most common causes of neighbourly friction in the UK. Here is a plain-English guide to your rights and responsibilities — who owns what, what you can and cannot cut, and the law on high hedges.

This is general guidance, not legal advice — for a specific dispute, check your property deeds and seek professional advice.

Who owns a boundary hedge?

Ownership usually comes down to your property deeds. A hedge growing just inside one boundary belongs to that owner; a hedge planted along the line itself may be jointly owned. Many deeds use a ‘T mark’ to show which side is responsible for a boundary — a T on your side means it is yours to maintain. If it is unclear, it is often treated as a shared responsibility, and a friendly conversation beats a formal dispute every time.

Can I cut my neighbour’s overhanging hedge?

Yes — in England and Wales you are entitled to cut back branches or roots that cross the boundary into your garden, but with three important caveats:

• You can only cut back to the boundary line, not beyond it.
• You cannot trespass onto your neighbour’s land to do the work without permission.
• The cuttings legally belong to the hedge owner — strictly, you should offer them back rather than dumping them over the fence.

Take care not to damage the health of the hedge, as you could be held liable. And if it is nesting season, the wildlife law applies too — see our guide on when you can cut hedges in the UK.

The law on high hedges

If a neighbour’s evergreen hedge has grown too tall and is blocking your light, the high hedges legislation (Part 8 of the Anti-social Behaviour Act 2003) may help. It applies to:

• a line of two or more mostly evergreen or semi-evergreen trees or shrubs;
• that is over 2 metres tall; and
• that acts as a barrier to light or access.

You are expected to try to resolve it directly with your neighbour first. If that fails, you can make a formal complaint to your local council (usually for a fee). The council can issue a remedial notice requiring the hedge to be reduced — though it cannot insist it is cut below 2 metres. The rules do not apply to a single tree or to deciduous hedges.

Planting a hedge near a boundary

There is no fixed legal distance for planting a hedge from a boundary, but it pays to be considerate:

• Plant slightly in from the line so you can maintain both sides from your own garden.
• Choose the right plant for the space — a vigorous conifer that wants to be 10m tall is a future dispute waiting to happen.
• Keep it trimmed so it does not encroach on your neighbour, the pavement, or sightlines for traffic.

If you want privacy without the risk of a high-hedge headache, choose a hedge you can comfortably keep at 2 metres — or consider pleached trees, which screen at first-floor level without forming a towering wall.

Your responsibilities as a hedge owner

• Keep your hedge trimmed so it does not obstruct pavements, roads or visibility at junctions and driveways.
• Do not let it grow so tall it could fall foul of the high hedges rules.
• Check for nesting birds before cutting in spring and summer.

Boundary hedge law FAQs

How tall can a hedge legally be in the UK?
There is no blanket height limit, but under the high hedges rules a council can require an evergreen hedge over 2 metres to be reduced if it is unreasonably blocking a neighbour’s light or access.

Can I make my neighbour cut their hedge?
Not directly, but if it is an evergreen hedge over 2m affecting your light, you can ask the council to step in under the high hedges legislation after trying to resolve it amicably.

Who is responsible for a boundary hedge?
Whoever owns it — usually shown by your property deeds. A hedge on the boundary line may be a shared responsibility.

Can I keep the branches I cut from my neighbour’s hedge?
Technically the cuttings belong to the hedge owner, so you should offer them back rather than keeping or dumping them.
