What is the law on boundary hedges? In short: a hedge belongs to the land its stem grows on; you may cut back growth that crosses your boundary (but must offer the cuttings back); and evergreen hedges over 2 metres can be challenged under the high hedges provisions of the Anti-social Behaviour Act 2003. Here is how the rules work in practice — and what to do when a hedge row turns into a boundary row.
Who owns a boundary hedge?
Ownership follows the stem: if it grows on your neighbour’s side of the legal boundary, it is theirs, even if half of it overhangs your garden. A hedge planted astride the line is jointly owned. Where deeds show a T mark against the boundary, that owner is usually responsible for the barrier — hedge or fence. Unsure where the line runs? That is a boundary survey question, not guesswork.
The 2-metre high hedge rule
For a hedge to fall under the high hedges regime it must be a line of two or more mostly evergreen or semi-evergreen trees or shrubs over 2 metres tall that blocks light or access. You must try to resolve it privately first; the council can then order a reduction (not removal) and fees of £300–£600 typically apply. Deciduous hedges and single trees are outside the scheme.
Overhanging branches and roots
You may prune growth back to the boundary line at your own cost without notice — but not beyond it, and not if a Tree Preservation Order or conservation area protects the plant. Cuttings legally remain the hedge owner’s property: offer them back rather than throwing them over the fence.
When hedges hide a boundary dispute
Many “hedge disputes” are really disagreements about where the boundary sits — especially when a hedge is removed and a fence appears in a different place. Land Registry plans show general boundaries only; a measured survey settles it. Related reading: who owns the fence and wall and fence height rules.
