A Neighbour’s High Hedge Blocking Light to a Conservatory: How Part 8 of the Anti-social Behaviour Act 2003 Works in England
In England a council can act on a neighbour’s high hedge, meaning two or more mostly evergreen trees or shrubs over two metres tall that act as a barrier to light or access, but it cannot order the hedge removed, cannot require it to be cut below two metres and cannot deal with root problems.
In this guide
Under Part 8 of the Anti-social Behaviour Act 2003 a council can, after a complaint, decide whether a neighbour’s high hedge, a line of two or more mostly evergreen trees or shrubs more than two metres tall that is a barrier to light or access, harms the reasonable enjoyment of a home or its garden, and can issue a remedial notice, but it cannot order removal, cannot require a height below two metres and cannot deal with roots.
What counts as a high hedge
Section 66 of the Anti-social Behaviour Act 2003 defines a high hedge as so much of a barrier to light or access as is formed wholly or predominantly by a line of two or more evergreens and rises to more than two metres above ground level. Evergreen includes semi-evergreen trees and shrubs. A line is not treated as a barrier if gaps significantly affect its overall effect at heights above two metres. GOV.UK guidance for England adds that the hedge must be on land owned or occupied by someone else, that a single tree or shrub does not qualify, and that height is measured from ground level, usually the base of the trunk or main stem. The guide covers England; Wales is not covered here.
How a conservatory fits into the test
The law asks whether the hedge’s height adversely affects the reasonable enjoyment of a domestic property. Under section 65, the complaint must come from an owner or occupier of a domestic property. GOV.UK says councils can consider harm to a home and/or its garden or yard, and a conservatory is part of the home, so the effect on it can be described in a complaint, which should explain what the problems are and how serious they are. GOV.UK also says the further the hedge is from the home, the harder it is to show harm. The guide to right to light covers the separate legal question of light lost to a neighbour’s building.
What has to happen before a complaint
The council can reject a complaint if it thinks the complainant has not taken all reasonable steps to settle the dispute without involving it, so steps to settle it informally come first. If the council accepts the complaint, GOV.UK says a fee will most likely be payable, that some councils offer reduced fees for people on a low income or benefits, and that the fee is not usually refunded even if the complaint succeeds. The complaint must be in writing, and GOV.UK says it should set out the steps taken to settle the dispute, the problems in the home or garden, why they are serious and how the hedge affects reasonable enjoyment.
What the council can and cannot order
If the council decides the hedge is adversely affecting reasonable enjoyment, it can issue a remedial notice setting out the action to be taken and by when. Under section 69, the notice must take effect at least 28 days after it is issued. The action specified cannot require the height of the hedge to be reduced to less than two metres above ground level or the removal of the hedge. GOV.UK says the legislation does not set a specific height and that two metres will only be the right height in some cases. The notice may also require the hedge to be kept at its new height, and the time allowed to cut it could be weeks or months, including extra time to protect birds nesting in the hedge, which links to the guide to nesting birds and conservatory building.
Roots and subsidence are outside the procedure
Section 65(4) states that Part 8 does not apply to complaints about the effect of the roots of a high hedge, and GOV.UK says the same about subsidence: hedge roots can take moisture from soils that shrink, but councils cannot deal with problems caused by roots. GOV.UK’s neighbour-disputes page separately says a person can trim branches or roots that cross into their property from a neighbour’s land, but only up to the boundary, and that exceeding this could lead to a court claim for damage. If the tree or hedge is protected, or in a conservation area, council permission may be needed before trimming, as explained in the guide to tree preservation orders and conservatories.
FAQs
Can a council make my neighbour remove a hedge blocking my conservatory?
No. GOV.UK says the council cannot order removal of the hedge, action that could kill it, or a height below 2 metres.
Does the process cover a single large tree?
No. GOV.UK says single trees or shrubs are not covered, although the parties can still try to settle the dispute informally.
Can I complain about roots damaging my conservatory foundations?
Not under this procedure. Section 65(4) says Part 8 does not apply to complaints about the effect of the roots of a high hedge.
The bottom line
In England, Part 8 of the Anti-social Behaviour Act 2003 lets a council act on a neighbour’s evergreen hedge over two metres tall that blocks light to a home or garden, including a conservatory, but only after reasonable steps to settle the dispute, usually with a fee, and with limits on what the notice can require. Roots and subsidence are outside it. This is general information, not legal advice.
