Tree Owners' Legal Responsibilities & Duty of Care
If you own land with trees on it, you have a legal duty of care to ensure those trees do not pose an unacceptable risk to people or property. This obligation applies to all landowners — homeowners, housing associations, local authorities, commercial property owners, schools, and estates — regardless of the size or number of trees involved.
Understanding your legal position and taking proportionate, documented steps to manage tree risk is the most effective way to meet your duty and protect yourself in the event of an incident.
The Legal Framework
The duty of care for tree owners in England and Wales arises primarily from the Occupiers' Liability Acts of 1957 and 1984, which require occupiers of land to take reasonable steps to ensure that their premises are reasonably safe for visitors and, in certain circumstances, trespassers. The duty applies not just to the land itself but to everything on it — including trees.
For commercial, institutional and public premises the Health and Safety at Work etc. Act 1974 also applies, imposing duties on employers and those in control of premises towards people who are not their employees.
The key principle established by the courts is one of reasonable foreseeability — a landowner is liable for injury or damage caused by a tree failure if it was reasonably foreseeable that the tree posed a risk and the landowner failed to take reasonable steps to identify and manage that risk. Where a landowner has carried out regular, professionally documented tree inspections and acted on the recommendations made, their legal position is significantly stronger than a landowner who has done nothing.
What Reasonable Steps Look Like
The courts and the Health and Safety Executive both look for evidence that a landowner has taken a systematic, proportionate approach to tree risk management. This means carrying out regular inspections by a suitably qualified person, keeping written records of those inspections and their findings, acting on management recommendations within a reasonable timeframe, and reviewing and updating the inspection programme as trees change and develop over time.
The National Tree Safety Group's Common Sense Risk Management of Trees, endorsed by the HSE, is the accepted national guidance and is explicit that the approach should be balanced and proportionate rather than exhaustive.
The appropriate frequency of inspection depends on the risk profile of the tree population — trees in high-target areas such as school grounds, public parks, housing estate paths, and car parks require more frequent inspection than trees in low-target rural locations. A qualified arboricultural consultant will advise on the appropriate inspection cycle for your specific site and tree population.
Who Has a Duty of Care
Every landowner has a duty of care for trees on land they own or manage. This includes:
- Private homeowners with trees in their garden
- Housing associations and registered providers managing communal estate trees
- Local authorities responsible for street trees, park trees, and housing estate trees
- Commercial property owners and facilities managers
- Schools, colleges, and universities
- Golf clubs, sports grounds and leisure facilities
- Private estates and landowners
Where land is leased, duties may fall on both parties — the owner holds the duty in negligence as owner of the trees, while the occupier holds the duty to visitors by virtue of its control of the premises. How responsibility is allocated between them is a matter for the lease, and it is worth establishing before an incident rather than after one.
The duty also extends to trees on boundary features, including boundary hedges and trees that overhang a neighbouring property or the public highway. Where a tree affects someone else's land, see our guidance on tree boundary and neighbour disputes.
Tree Preservation Orders & Conservation Areas
Where a tree is subject to a Tree Preservation Order or is located in a conservation area, additional legal obligations apply under the Town and Country Planning Act 1990. Carrying out works to a TPO-protected tree without the written consent of the local planning authority — or failing to give six weeks' notice for works to trees in a conservation area — is a criminal offence carrying an unlimited fine.
The duty of care obligation to manage risk does not override the requirement to obtain consent, but it does provide a justification for emergency works where there is an immediate risk of serious harm. That exemption is narrow and it is worth being certain it applies before relying on it — the burden of demonstrating that the works were genuinely urgent falls on whoever carried them out.
Urban Tree Management advises landowners on TPO obligations and submits applications on their behalf — see our protected trees advice page for further information.
Documenting Your Duty of Care
The most important protection available to a landowner in the event of a tree-related incident is a clear, professionally produced, written record of inspection, assessment, and action.
A well-documented tree inspection programme — carried out by a qualified arboricultural consultant, recording the condition and risk rating of every tree inspected, and demonstrating that recommended works have been carried out within reasonable timescales — provides defensible evidence that your duty of care is being actively and proportionately managed.
It is worth being clear about what is actually examined after an incident. Not whether the tree failed, but whether a system existed, whether it was reasonable, whether it was followed, and whether the person carrying out the inspections was competent to do so. All four are answered with documents.
Urban Tree Management provides tree inspection and risk assessment reports in a format that builds this audit trail systematically over time. For larger tree populations and multi-site estates, our tree risk management programmes provide the policy and zoning framework that sits above the surveys, and this work is available on a retained basis with tracked reinspection dates so nothing lapses.
Frequently Asked Questions
Am I legally required to have my trees inspected?
No statute specifies an inspection interval. The duty arises under the Occupiers' Liability Acts 1957 and 1984, the Health and Safety at Work etc. Act 1974 for commercial premises, and common law negligence. The requirement is to take reasonable and proportionate steps to manage foreseeable risk — and regular inspection by a competent person, properly recorded, is the accepted way of demonstrating that.
How often should trees be inspected?
It depends on the trees, their condition, and how heavily the surrounding area is occupied. Twelve to thirty-six months is common for occupied areas, with longer intervals defensible for low-target land. The interval should be a recorded professional judgement with reasons, not a default applied because it is the default.
Am I liable if a tree falls and causes damage?
Potentially, where the risk was reasonably foreseeable and you failed to take reasonable steps to identify and manage it. A landowner who has inspected, recorded, and acted is in a very different position from one who has done nothing — even where the outcome is the same.
Who is responsible where the land is leased?
Potentially both parties. The owner holds the duty in negligence as owner of the trees; the occupier holds the duty to visitors through its control of the premises. How that is allocated is a matter for the lease, and it is worth establishing in advance.
What about a neighbour's tree overhanging my property?
That is a different question, covered on our page on tree boundary and neighbour disputes. This page concerns your duty as the owner of a tree; that one concerns your position in relation to somebody else's.
