Most people insure their house against the things that frighten them - fire, flood, a break-in - and never think about the thing that is far more likely to cost them money. It is not the building. It is the garden, and specifically what happens when a child, a neighbour, a delivery driver or a falling branch turns an ordinary afternoon into a claim. Homeowner liability in a UK garden is one of the least understood parts of owning a home, and the gaps tend to be found the hard way.
As the occupier of your property you owe a legal duty of care to people who come onto it - and, in limited circumstances, to people who come onto it without permission. Most of the risk sits in four ordinary places: trampolines, water, trees, and boundaries. None require you to live in fear. They require you to inspect, fix what you find, and keep evidence that you did.
Why “occupier” matters more than “owner”
The relevant duties in England and Wales sit in the Occupiers’ Liability Act 1957, which covers lawful visitors, and the Occupiers’ Liability Act 1984, which covers people who are not lawful visitors at all. Scotland has its own equivalent framework. The practical point is the word occupier: it is the person in control of the premises who carries the duty, which is why a landlord, a tenant and a homeowner can all be occupiers in different situations.
What that duty asks of you is reasonableness - not perfection, but the care that is reasonable in the circumstances to see that people are reasonably safe. Courts also take into account that children are less careful than adults, which is precisely why the four hazards below keep appearing.
Trampolines
A trampoline in a British back garden is an attraction, and an attraction is a problem when the children using it are not yours. Neighbours’ children climbing a fence to use a trampoline are, technically, trespassing - and the 1984 Act still creates a duty in some circumstances where you know of a danger and know that people are likely to come near it.
The practical steps are not complicated. Maintain the safety net rather than leaving it collapsed over winter, anchor the frame properly, and replace the spring padding when it perishes. Then check your insurance wording, because some insurers ask to be told about a trampoline and some exclude it altogether. An exclusion you did not know about is the expensive version of this problem.
Ponds and water features
Water in a garden is the hazard with the worst possible outcome and the least visible warning. A small child can drown in very little water, and a pond that is perfectly safe in March is invisible under duckweed in August.
If you have young children or young visitors, the honest options are to fence the pond, cover it with a rigid mesh grille rated to take a child’s weight, or fill it in. Token solutions satisfy nobody afterwards. If you inherit a pond when you buy a house, deal with it in your first month rather than your first summer.
The uncomfortable truth about garden liability is that most of it is not about accidents at all - it is about things the homeowner already knew were a problem and had not got round to. A rotten branch you had noticed, a fence panel you had propped up, a pond net that had sagged. The known-and-ignored hazard is the one that turns a sad accident into a contested claim.
Trees, roots and overhanging branches
Trees generate more neighbour disputes than anything else in a British garden, and they carry a genuine legal duty. As the owner of a tree you are expected to take reasonable care that it does not cause harm - which in practice means inspecting it periodically and acting on what you see.
What you are responsible for
Falling branches and failed trees. If a tree was visibly diseased, dead or damaged and you did nothing, the position is very different to a healthy tree coming down in an exceptional storm.
Roots. Roots that damage a neighbour’s drains, drive or foundations can create a liability, and subsidence caused by tree roots is a well-established category of claim.
Overhanging branches. Your neighbour is generally entitled to cut back growth that crosses the boundary, back to the boundary line - but the cuttings remain your property, and they cannot simply enter your garden to do it.
What changes the picture
Two things stop you touching a tree at all: a Tree Preservation Order, and being in a conservation area, where notice must normally be given to the council first. Check with your local authority before instructing anyone, because doing the work first is an offence rather than an oversight. Where a tree is large or close to a building, a survey from a qualified arboriculturist, repeated on a sensible cycle, is your evidence that you inspected it.
Boundaries, walls and fences
A leaning garden wall or a rotten fence post is a liability waiting to fall on somebody. The first question is whose structure it is - the deeds and title plan are the starting point, though less definitive than people expect. The second is condition, which is entirely on the occupier. High hedges are their own category: where an evergreen hedge blocks a neighbour’s light there is a local authority complaint route in England and Wales, but only after the neighbours have tried to resolve it themselves.
What to do in the next 30 minutes
Find your home insurance schedule and read the public liability section - check the limit and look for garden, trampoline or pond exclusions.
Walk the garden and photograph anything you already know is a problem, with today’s date.
Look up at your largest tree and note any dead wood, splits, or fungus at the base.
Check with your council whether any of your trees are protected or in a conservation area.
Put a reminder in the diary to repeat that inspection every six months.
The evidence that you inspected is worth as much as the inspection. Dated photographs, arboriculture reports, the fencing contractor’s receipt, the insurance schedule - keep your liability evidence in Home+ so it is in one place and time-stamped, rather than scattered across a camera roll and a drawer.
FAQ
Am I liable if a neighbour’s child is hurt on my trampoline without permission? Possibly. The 1984 Act can create a duty towards people who are not lawful visitors where you know of a danger and know people are likely to encounter it. Maintaining the equipment, keeping the net up and restricting access all matter.
Do I have to tell my insurer about a trampoline or a pond? Check your policy wording. Some insurers ask to be told, some apply conditions, and some exclude certain equipment entirely. Telling them costs nothing; not telling them can cost a claim.
My neighbour’s tree overhangs my garden. Can I cut it back? Generally you may cut back growth to the boundary line, but not beyond, and the cuttings belong to the tree’s owner. If the tree is protected by a Tree Preservation Order or sits in a conservation area, you must not cut it without the council’s consent.
Who is responsible for a fence between two gardens? It depends on the title deeds and any boundary agreement, and the answer is often less clear than either neighbour assumes. Whoever owns it is responsible for keeping it in a safe condition.
Does my home insurance cover garden liability automatically? Most buildings and contents policies include public liability cover as standard, but limits, exclusions and conditions vary between insurers. Read the schedule rather than assuming.
What records should I keep? Dated inspection photographs, tree survey reports, repair invoices, correspondence with neighbours, and your current insurance schedule. If a claim is made, that file is the difference between an argument and a fact.
