Occupiers' liability is the area of tort law that deals with the duties owed by people who control premises to those who come onto those premises. It used to be a messy patchwork of common law categories, but two statutes now govern the field: the Occupiers' Liability Act 1957 (covering lawful visitors) and the Occupiers' Liability Act 1984 (covering trespassers and others without permission). Your job in the exam is to figure out which regime applies and then apply the right test.
Occupiers' liability questions often involve a fact pattern where someone is injured on someone else's property. Start by asking: was the claimant a visitor or a non-visitor? That single question determines which Act applies, and each has very different rules. Get that classification wrong and the whole analysis falls apart.
The term "occupier" is not defined in either Act, but the courts have given it a clear meaning. An occupier is anyone who has a sufficient degree of control over premises. You do not have to own the property or even be there all the time. The key question is whether you have the ability to take steps to make the premises safe. If you can fix a danger or warn about it, you are probably an occupier.
More than one person can be an occupier of the same premises at the same time. This is a really important point. In Wheat v Lacon [1966], a married couple managed a pub for the brewery that owned it. A customer was killed by another customer on the stairs. The court held that both the brewery (as owner) and the couple (as managers in day-to-day control) could be occupiers. Each was liable to the extent of their control.
The definition of premises is deliberately broad. Under OLA 1957 s.1(3)(a), it includes any land, buildings, and other structures. It also covers fixed and moveable structures, vessels, vehicles, and aircraft. So you could have an occupiers' liability claim relating to a ship, a caravan, scaffolding on a building site, or even a car parked on a driveway. If someone has control over a space or structure and someone else gets injured there, it could fall within occupiers' liability.
The most important distinction in this topic is between visitors and non-visitors. A visitor is someone who enters the premises with the express or implied permission of the occupier. A non-visitor is someone who has no permission to be there — typically a trespasser, but also someone who exceeds their permission (goes where they are not allowed) or someone whose original permission has been revoked. The rules are very different for each category, so getting this right is essential.
Visitors come in several forms. An invitee is someone invited onto the premises for a business or public purpose — like a customer in a shop. A licensee is someone with social permission — like a friend visiting your home. Both are treated as visitors under OLA 1957 and get the same protection. The old common law distinction between invitees and licensees has been abolished by the 1957 Act.
Sometimes a person enters premises under a contract. Under OLA 1957 s.2(6), where a person enters premises in the exercise of a right conferred by a contract, they are treated as a visitor. So a meter reader, a builder doing work under a contract, or a tenant under a lease are all visitors. However, where the contract itself deals with the duty of care, the contractual terms may take precedence.
Section 2(1) is the heart of the 1957 Act. It imposes a "common duty of care" on the occupier towards all visitors. The duty is to take such care as in all the circumstances of the case is reasonable to see that the visitor will be reasonably safe in using the premises for the purposes for which they are invited or permitted to be there. Note the double "reasonably" — the care must be reasonable, and the visitor must be reasonably safe. It is not a guarantee of absolute safety.
Think of the common duty of care as similar to the negligence duty, but with a helpful statutory framework already built in. You do not need to prove a separate duty of care — the statute provides it. You just need to show that the occupier failed to take reasonable care and that this caused the injury.
Section 2(2) makes clear that the duty is owed to all visitors, regardless of why they are there. It does not matter whether the visitor is there for business, social reasons, or any other purpose. The occupier owes the same basic duty to everyone lawfully on the premises. However, the standard of care may vary depending on what the occupier knows or should know about the particular visitor.
Under s.2(3)(a), where the occupier knows (or has reasonable grounds to believe) of a danger on the premises, and the visitor is unlikely to discover it, the occupier has a duty to warn the visitor of the danger. The warning must be sufficient to enable the visitor to avoid the danger. Simply pointing in the general direction of a hazard may not be enough — the warning must be clear and specific enough to be effective.
A warning notice is not an automatic get-out for the occupier. Under s.2(4)(a), a warning does not absolve the occupier from their duty unless in all the circumstances it is enough to make the visitor reasonably safe. If a child is too young to read or understand a warning sign, the warning will not discharge the duty. Similarly, a warning about a hidden danger may not help if the visitor has no realistic way to act on it.
Section 2(4) requires the occupier to be prepared for children to be less careful than adults. When you know (or should know) that children are likely to visit the premises, you must expect that a child will be less careful than an adult would be. This does not mean the occupier must make the premises child-proof, but they must consider what a child might reasonably do and take steps accordingly.
This is the leading case on children and occupiers' liability. A seven-year-old child died after eating poisonous berries from a tree in a public park. The berries were attractive to children but no warning signs were posted. The court held the corporation liable. They knew children used the park, knew the berries were poisonous, and knew children would be attracted to them. A simple warning sign would have prevented the death. This is sometimes called the "attractive nuisance" principle.
Remember that a warning sign may not discharge the duty to a child. If the child is too young to read, or too young to understand the warning, it will not be effective. The occupier may need to take physical steps to prevent access to the danger — like fencing it off or removing it entirely.
Section 2(5) provides a reduced duty towards visitors who are there in a professional capacity. When a visitor is there to examine the premises for a professional purpose — like a surveyor inspecting a building or an electrician checking wiring — the occupier may discharge their duty by giving the visitor sufficient information about any dangers they would not discover in the course of their professional examination. Essentially, professionals are expected to know their job and spot obvious risks.
The 1957 Act does not make the occupier liable for damage caused by the work of an independent contractor. However, the occupier must still exercise reasonable care in selecting a competent contractor. If the occupier hires a contractor they know (or should know) is incompetent, they can be held liable for the foreseeable consequences. So you cannot just outsource safety and wash your hands of it — you need to choose your contractors carefully.
Section 4 extends the occupier's duty to cover the state of the premises and things done to them. This includes fixtures, fittings, furniture, and equipment provided for the use of visitors. The occupier must take reasonable care to ensure these are safe. For example, if you provide chairs in a waiting room, you must ensure they are not broken or dangerous. If a light fitting you installed falls and injures a visitor, you are liable if you failed to maintain it properly.
Section 4 also covers things brought onto the premises by third parties, but only where the occupier has given permission for them and has the ability to control or remove them. For instance, if a shop allows a supplier to install a display and the display collapses, the shop occupier may be liable if they had the power to ensure it was safely installed.
| Case | Facts | Principle |
|---|---|---|
| Wheat v Lacon [1966] | A customer was killed on stairs at a pub managed by a married couple for the brewery that owned it. | Both the brewery (owner) and the couple (in day-to-day control) were occupiers. Multiple people can share occupier status simultaneously. |
| Wheeler v Copas [1981] | A tenant farmer let a meadow for grazing. The tenant's horse was injured by rabbit holes hidden in the long grass. The landlord had recently taken back possession of the field. | The landlord was not liable because he did not know and had no reason to know about the rabbit holes. An occupier is not liable for hidden dangers they are unaware of. |
| Roles v Nathan [1963] | Two workmen were overcome by fumes while installing a gas heater in a basement. The occupier had warned them it was dangerous but they went in anyway. | The workmen were visitors, but the occupier was not liable because the danger was known to the visitors. Under s.2(3)(a), there is no duty to warn of dangers the visitor already knows about. |
| Glasgow Corporation v Taylor [1922] | A child ate poisonous berries from a tree in a public park and died. No warning signs were displayed. | The occupier was liable because they knew children used the park, knew the berries were poisonous and attractive to children, and failed to take reasonable precautions. |
| Tomlinson v Congleton BC [2003] | A man ignored warning signs and dove into a shallow lake in a country park, sustaining serious injuries. The council had previously tried to deter swimming. | The House of Lords held the council was not liable. The danger was obvious, and the warning signs were sufficient. An occupier is not required to protect people from obvious risks they choose to take. |
Tomlinson is important because it shows the limits of occupiers' liability. The House of Lords was clear that the law does not require occupiers to protect adults from obvious dangers they freely choose to encounter. Warning signs, fences, and other measures may be enough even if they do not completely prevent the risk.
Before 1984, the common law position on trespassers was set out in the controversial case of British Railways Board v Herrington [1972], which had replaced the even harsher rule from Addie v Dumbreck [1929]. Parliament decided to put the law on a statutory footing, and the result was OLA 1984. The key thing to understand is that the 1984 Act sets a lower standard of protection for non-visitors compared to the 1957 Act. The occupier does not owe an automatic duty — conditions must be met first.
Under s.1(3), an occupier owes a duty to a non-visitor only when all three conditions are satisfied. This is a cumulative test — all three must be met, or there is no duty at all. Think of it as three hurdles the claimant must clear before any duty arises.
Even if all three conditions in s.1(3) are met, the duty owed to a non-visitor is lower than the duty owed to a visitor. Under s.1(4), the occupier must take such care as is reasonable in all the circumstances to see that the non-visitor does not suffer injury. But there is no equivalent of the "common duty of care" from the 1957 Act. The focus is on what the occupier can reasonably do, not on making the premises safe for the non-visitor.
Do not assume the occupier owes a duty to a trespasser. The claimant must satisfy all three conditions in s.1(3). If the occupier does not know about the danger, or does not know the trespasser is around, or it would be unreasonable to expect them to act, there is simply no duty. This is very different from the 1957 Act, where the duty arises automatically.
Section 1(6) provides that no duty is owed under the 1984 Act in respect of risks willingly accepted by the non-visitor. The section states that where the danger is obvious to the non-visitor, the occupier may reasonably expect them to protect themselves. This does not mean a danger must be glaringly obvious — but it does mean that if a reasonable person in the non-visitor's position would appreciate the risk, the occupier does not have to protect them from it.
Tomlinson is the leading case on obvious risks and it applies to both the 1957 and 1984 Acts. Mr Tomlinson ignored prominent warning signs and dove headfirst into a shallow lake, breaking his neck. The council had put up signs saying "Dangerous Water — No Swimming." The House of Lords held the council was not liable under either Act. The risk was obvious, and a reasonable adult would understand the danger of diving into unknown water. The council had done enough by warning people and providing alternatives (a nearby swimming pool).
This case arose alongside Tomlinson and reinforced the same principle. A young person was injured while playing on a rope swing over the sea at a disused quarry. The Court of Appeal held the occupier was not liable. The danger was obvious — swinging over a cliff edge into the sea carries obvious risks. The occupier had taken reasonable steps by erecting warning signs and fencing off the area. The claim failed under OLA 1984.
These two cases from the House of Lords and Court of Appeal are often cited together. They stand for the principle that occupiers are not expected to make their premises completely safe from every conceivable risk. When a danger is obvious and the claimant freely chooses to encounter it, the law will not impose liability. This is an important policy limit on occupiers' liability.
| Case | Facts | Principle |
|---|---|---|
| Tomlinson v Congleton BC [2003] | Man ignored warning signs and dove into shallow lake in a country park, suffering serious injury. | No liability. The risk was obvious. The occupier had taken reasonable steps by erecting signs and providing alternatives. Adults who choose to take obvious risks cannot blame the occupier. |
| Donoghue v Folkestone Properties [2003] | Young person injured on a rope swing over the sea at a disused quarry with warning signs and fencing. | No liability under OLA 1984. The danger was obvious. Warning signs and fencing were reasonable steps. The court would not impose a duty where the claimant freely chose to take an obvious risk. |
Volenti non fit injuria means "to a willing person, no injury is done." It is a complete defence — if it succeeds, the claimant gets nothing. For volenti to apply, the claimant must have full knowledge of the risk and voluntarily accepted it. In the context of occupiers' liability, this is most relevant where someone knowingly enters dangerous premises despite being aware of the danger. The key cases on obvious risk, like Tomlinson, often overlap with volenti principles.
Under the Law Reform (Contributory Negligence) Act 1945, contributory negligence is a partial defence. If the claimant was partly to blame for their own injury, the court can reduce their damages by a proportion it considers just and equitable. In occupiers' liability, this commonly arises where the visitor ignored a warning sign, entered a clearly dangerous area, or failed to take reasonable care for their own safety. It does not wipe out the claim — it just reduces the damages.
Do not confuse these two defences. Volenti is a complete defence (claimant gets nothing) and requires full, voluntary acceptance of the risk. Contributory negligence is a partial defence (damages are reduced) and only requires the claimant to have failed to take reasonable care for their own safety. The evidential threshold for volenti is much higher. In most exam scenarios, contributory negligence will be the more realistic defence.
The defence of ex turpi causa (from a dishonourable cause) may apply where the claimant was injured while engaged in criminal activity on the premises. For example, a burglar injured while breaking into a property might have their claim barred by illegality. However, following Patel v Mirza [2016], the court takes a proportionate approach, considering the connection between the illegality and the claim, public policy, and other factors. It is not an automatic bar.
Under OLA 1957 s.2(4)(a), a warning notice is not a complete defence but may discharge the duty if it is sufficient to make the visitor reasonably safe. The warning must be clear, specific, and understandable. For children, a written sign is unlikely to be enough unless the child can read and understand it. For non-visitors under OLA 1984, s.1(6) means that where the risk is obvious, the occupier can expect the non-visitor to protect themselves — effectively making the obviousness of the risk a defence.
Under s.2(5), where a visitor visits the premises for a professional purpose, the occupier may discharge their duty by giving sufficient information about any dangers that the visitor would not discover in the course of their professional examination. This reflects the idea that professionals — like surveyors, engineers, or tradespeople — are expected to spot many risks themselves. The duty is reduced because the visitor has special knowledge and skill.
| Defence | Type | Effect | Key Requirement |
|---|---|---|---|
| Volenti non fit injuria | Complete | Claim dismissed entirely | Claimant had full knowledge and voluntarily accepted the risk |
| Contributory negligence | Partial | Damages reduced proportionately | Claimant failed to take reasonable care for their own safety |
| Ex turpi causa | Full or partial | Depends on circumstances | Claimant's injury connected to illegal conduct |
| Warning notice | May discharge duty | No liability if sufficient | Warning must be clear enough to make the visitor reasonably safe |
| Special knowledge | Reduces duty | Duty limited to warning | Visitor is a professional visiting for professional purposes |
Section 65 of the 1957 Act provides that the common duty of care cannot be excluded or restricted by any contract term or notice. This means an occupier cannot put up a sign saying "Enter at your own risk" and escape liability to visitors. Even if the visitor signed a waiver, the occupier cannot contract out of their statutory duty. This is a strong protection for visitors and reflects the policy that occupiers should not be able to dodge their responsibilities.
There is no reasonableness test under s.65. The exclusion simply has no effect, regardless of how reasonable or clear it is. A shop cannot display a sign saying "Not responsible for accidents on these premises" and expect it to work. Any attempt to exclude liability to visitors under OLA 1957 is void.
Section 13 of the 1984 Act provides that the duty owed to non-visitors cannot be excluded or restricted by notice. So an occupier cannot put up a sign saying "Trespassers will be prosecuted" or "Private property — enter at your own risk" and rely on that to avoid liability to a trespasser who is injured. However, note that s.13 only covers exclusion by notice — it does not mention exclusion by contract, which may still be relevant in some situations.
The Unfair Contract Terms Act 1977 also interacts with occupiers' liability. Under UCTA s.2(1), a person cannot exclude or restrict liability for death or personal injury resulting from negligence. For other loss or damage (like property damage), exclusion is subject to a reasonableness test under s.2(2). This means that even outside the specific provisions of the 1957 and 1984 Acts, UCTA provides an additional layer of protection.
| Feature | OLA 1957 (Visitors) | OLA 1984 (Non-Visitors) |
|---|---|---|
| Who is covered? | Lawful visitors with express or implied permission | Trespassers and those without permission |
| Does duty arise automatically? | Yes — the common duty of care arises when a visitor enters | No — all three conditions in s.1(3) must be met first |
| Standard of care | Take reasonable care to see visitor reasonably safe | Take reasonable care to see non-visitor does not suffer injury |
| Duty to children | Higher duty — occupier must expect children to be less careful | No specific provision, but children may be treated differently |
| Exclusion by contract | Cannot be excluded (s.65) | Not specifically addressed by s.13 |
| Exclusion by notice | Cannot be excluded (s.65) | Cannot be excluded by notice (s.13) |
| Warnings | May discharge duty but not automatically (s.2(4)(a)) | No duty for obvious risks (s.1(6)) |
Occupiers' liability exists alongside the general law of negligence. In many cases, a claimant could bring a claim under either the statutory regime or common law negligence. The statutes codify and modify the common law duty in the specific context of premises, but they do not replace it entirely. In practice, if the statutory test is met, the claimant will usually rely on the statute because it provides a clear framework. But common law negligence may still be relevant, for example where the claim involves an omission to act or a failure to maintain premises.
There is significant overlap between occupiers' liability and employers' liability when an employee is injured at work. The employer is both an occupier of the workplace (under OLA 1957) and owes a separate duty of care as an employer. In most cases, the employee will be a lawful visitor to the premises, so OLA 1957 applies. But the employer's primary liability (from Wilsons and Clyde Coal v English [1938]) — the duty to provide competent staff, adequate equipment, and a safe system of work — runs alongside and sometimes beyond the occupiers' liability duty.
In an exam question where an employee is injured at work, mention both employers' liability and occupiers' liability. The employer owes duties under both heads. The employers' liability duties are broader (covering safe systems of work and competent staff) while occupiers' liability focuses on the physical condition of the premises. The employee does not have to choose — they can rely on both.
The question of when a landlord becomes an occupier arises frequently. As a general rule, a landlord who lets premises in disrepair is not an occupier of those premises once the tenant takes possession. The landlord loses control and therefore loses occupier status. However, a landlord can be an occupier in certain situations: when they retain control of common parts (staircases, hallways, lifts), when they carry out repairs negligently, or when they let premises knowing they are dangerous and fail to warn the tenant.
The Defective Premises Act 1972 creates additional statutory duties for landlords and builders. Under s.4, a landlord who lets dwelling premises owes a duty to the tenant and others who might reasonably be expected to be affected by defects. The duty is to ensure the premises are reasonably fit for human habitation at the start of the tenancy. Under s.1, anyone who carries out work of construction, extension, or repair of a dwelling owes a duty to see the work is done in a workmanlike manner with proper materials. This overlaps with occupiers' liability but is separate.
