Background
The law governing liability for accidents occurring on land or premises developed originally through the common law of occupiers’ liability. Historically, the duty owed by an occupier depended on the legal status of the person entering the land. Visitors were divided into categories such as invitees, licensees, and trespassers, and the level of protection varied depending on the category into which the claimant fell.
This system became increasingly complex and was widely criticised for being overly technical and producing unfair outcomes. For example, the duty owed to a visitor might depend on subtle distinctions about whether the person had entered the land for the occupier’s benefit or with permission. Courts were required to apply complicated rules that often focused more on the legal classification of the visitor than on the practical question of whether the occupier had acted reasonably.
In response to these concerns, Parliament introduced a series of statutes designed to modernise and simplify the law relating to liability for land and premises. The most important pieces of legislation are the Occupiers’ Liability Act 1957, the Defective Premises Act 1972, and the Occupiers’ Liability Act 1984. Together, these statutes form the core statutory framework governing liability for injuries caused by unsafe premises.
Purpose of the Legislation
The Occupiers’ Liability Act 1957 introduced a major reform by replacing the complicated common law rules governing invitees and licensees with a single duty known as the “common duty of care.” Under this Act, occupiers owe a duty to take reasonable care to ensure that lawful visitors are reasonably safe when using the premises for the purposes for which they are invited or permitted to be there.
The Act recognises that the standard of care required may vary depending on the circumstances. For example, occupiers must expect that children may be less careful than adults, and they may assume that skilled professionals will guard against risks associated with their work. The Act also allows occupiers, in some circumstances, to restrict or exclude liability through warnings or contractual terms.
The Defective Premises Act 1972 introduced further protections relating to the construction and maintenance of buildings. It imposes duties on builders, developers and others involved in constructing or repairing dwellings to ensure that the work is carried out properly and that the property is fit for habitation. The Act also introduced duties on landlords in certain circumstances where they have obligations to repair or maintain premises.
The Occupiers’ Liability Act 1984 later extended the law to cover persons who enter land without permission, including trespassers. Under this Act, occupiers may owe a duty where they are aware of a danger and know that people may come into the vicinity of that danger. The duty requires occupiers to take reasonable steps to protect such persons from injury where it is reasonable to do so.
Together, these statutes shifted the focus of the law away from rigid classifications of visitors and towards a broader assessment of reasonable safety and responsibility.
2026 update
The statutory framework created by the Occupiers’ Liability Act 1957, Defective Premises Act 1972, and Occupiers’ Liability Act 1984 remains central to modern premises liability in England and Wales. Courts continue to interpret these statutes alongside the general principles of negligence in determining whether an occupier has taken reasonable care to prevent injury.
Recent legal developments have focused particularly on the Defective Premises Act 1972. The Building Safety Act 2022 significantly extended limitation periods for certain claims relating to defective construction, allowing some claims to be brought many years after the original building work was completed. This reform was introduced in response to concerns about unsafe building practices following the Grenfell Tower fire.
As a result, while the fundamental principles governing occupiers’ liability remain largely unchanged, modern litigation increasingly reflects building safety regulation, landlord responsibilities, and construction liability, particularly in cases involving defective residential buildings.
