Neighbour's Trees: Your Legal Rights and How to Get Council Action

Overhanging branches, light-blocking hedges, and roots damaging your foundations are among the most common disputes between neighbours in the UK — and also some of the most misunderstood in terms of what you can do and who bears the cost. This guide covers the legal position, the formal routes available to you, and realistic cost expectations.

The Common Law Position: What You Can Do Without Asking

Under common law, you have the right to cut back any overhanging branches or encroaching roots to the boundary line, without the need for your neighbour's permission. This right is known as the self-help remedy.

Important rules apply:

• You must offer the cuttings back to your neighbour — the branches and fruit legally belong to them, and disposing of them without offering them back can technically constitute a conversion of their property
• You may not enter your neighbour's land to carry out the work — you can only cut from your side of the boundary
• You may not cut back further than the boundary, even if you believe the root system extends further
• If the tree is protected by a TPO (see below), even cutting branches from your side may require prior consent from the council

In practice, cutting overhanging branches that are simply inconvenient (rather than dangerous) is low-risk legally. However, if the tree is valuable and severe cutting causes it to die or become unstable, you may face a claim for the diminished value of the tree.

High Hedges: The Formal Complaint Route

The Anti-social Behaviour Act 2003, Part 8 gives homeowners the right to complain to their local council about high hedges that are affecting their reasonable enjoyment of their property. Key qualifying conditions:

• The hedge must be evergreen or semi-evergreen — deciduous hedges do not qualify
• It must consist of two or more trees or shrubs (a single large tree does not qualify as a hedge under the Act)
• It must be over 2 metres in height
• It must be adversely affecting your reasonable enjoyment of your home or garden — this is judged objectively by the council

The Council Complaint Process

1. Attempt direct negotiation with your neighbour — councils will check that you have done this before accepting a complaint
2. Submit a formal complaint to your council using their high hedge complaint form, along with supporting evidence (photographs, correspondence with the neighbour)
3. Pay the council fee: this varies by council but typically ranges from £400 to £700 (this is a cost you pay, not the neighbour — it is not recoverable unless the council's decision is upheld on appeal)
4. The council investigates and may issue a remedial notice requiring the hedge to be reduced to a specified height (often 2–2.5m above ground level, depending on site context)
5. If the neighbour fails to comply, the council can carry out the works and recover costs from the neighbour
6. Either party can appeal to the Planning Inspectorate — appeals are free and determined by a planning inspector on the papers

The process typically takes 3–6 months from complaint submission to decision. It can take longer if the council is slow to process or if an appeal is lodged.

Tree Preservation Orders (TPOs)

A Tree Preservation Order (TPO) is a council designation that protects specific trees or groups of trees from being felled, topped, or significantly pruned without consent. TPOs are made under the Town and Country Planning Act 1990.

How to Check Whether a Tree Is Protected

• Your council's planning portal should show TPO locations on an interactive map
• You can also submit a general enquiry to the council's tree officer
• Trees in conservation areas have automatic protection equivalent to a TPO — no individual designation is needed

What This Means for You

If your neighbour's tree is protected by a TPO:

• Your neighbour cannot cut it without council consent, even if it is damaging your property
• You cannot cut it from your side of the boundary without council consent (including the self-help remedy)
• If you cut a TPO tree without consent, you commit a criminal offence (unlimited fine under s.210 TCPA 1990)

If a protected tree is causing structural damage to your property, the correct route is to report this to the council's tree officer and request a survey. Councils can grant consent for works under a TPO where safety or structural damage is the justification — but they will want evidence, typically an arborist's report.

Root Damage: Subsidence, Drains, and Legal Liability

Tree roots from a neighbouring property can cause two types of damage:

Subsidence

Roots from large trees — particularly willows, oaks, and poplars — can desiccate clay soils, causing differential settlement (subsidence) under foundations. This is most common in dry summers on shrinkable clay.

Insurance position: your buildings insurance should cover subsidence claims. Report the damage to your insurer and let them pursue the neighbour if the tree is the cause.

Legal liability of tree owner: under the law of nuisance, a tree owner can be liable for foreseeable damage caused by roots or branches to a neighbouring property. Following Delaware Mansions Ltd v Westminster City Council [2001] and Robbins v Jones [1863], a tree owner who is aware of the encroachment and fails to take reasonable steps can be held liable. The claimant must show that the damage was foreseeable and that the tree owner had actual or constructive knowledge of the risk.

Rylands v Fletcher (strict liability for things likely to do mischief if they escape) has been considered in tree damage cases but is rarely the primary cause of action in modern practice — nuisance is more commonly relied upon.

Drain Damage

Tree roots can infiltrate drainage systems through joint cracks, causing blockages and collapse. If you suspect a neighbouring tree is the cause of drain problems:

1. Commission a CCTV drain survey (£150–£400) to document the damage and root intrusion
2. Send a letter before action to the neighbour's solicitor citing the survey findings and requesting repair costs
3. If the neighbour declines, issue proceedings in the small claims court (under £10,000) or county court (over £10,000)

Knotweed and Trees: A Related Problem

If the issue involves a neighbour's Japanese knotweed rather than trees, note that the legal routes differ significantly. Knotweed encroachment is a specific nuisance tort following Network Rail Infrastructure Ltd v Williams [2018] and involves the Property Care Association's treatment regime and insurance-backed guarantees. For that specific problem, see our Japanese knotweed on neighbouring land guide.

Right to Light: A Brief Distinction

If your complaint is that a tree or hedge is blocking light to your windows, this may give rise to a right to light claim under the Prescription Act 1832 — but only if you have enjoyed the light for 20 years without interruption. This is a separate area of law from high hedges and nuisance, and is not covered by the Part 8 high hedge complaint process. It involves different legal principles and typically requires specialist property law advice. For a full guide to right to light law, see our right to light UK guide.

Practical Checklist

1. Check for a TPO on the council's planning portal before touching the tree from your side
2. Log everything in writing — photograph the issue, send letters or emails to the neighbour (not just verbal), keep a dated record
3. For high hedges: make one genuine written attempt to resolve before filing the council complaint — the council will ask for evidence of this
4. For root damage: get a professional survey before contacting the neighbour formally — without evidence of cause, a letter is easily dismissed
5. Do not withhold any part of the shared boundary obligation (fence maintenance, etc.) in retaliation — this can compromise your legal position
