Negligence in English law

Negligence is the dominant tort in English law. It provides the principal mechanism by which one party may recover compensation from another for loss caused by careless conduct. In its modern form, negligence requires the claimant to establish four elements: that the defendant owed a duty of care, that the defendant breached the applicable standard of care, that the breach caused the claimant’s loss, and that the loss suffered was not too remote. Each of these elements has generated its own substantial body of case law and scholarly commentary, and each involves distinct legal tests. But negligence is more than the sum of its constituent parts. It is, as a unified tort, the product of a remarkable historical evolution — from a set of scattered, status-based obligations into a general principle of civil liability grounded in fault.

This guide provides a comprehensive account of negligence as a whole: its historical roots, the landmark decisions that shaped its modern architecture, the structure and interplay of its core elements, its principal defences, and its continuing development. Where individual elements of negligence – duty of care, foreseeability, intervening cause, and others — are treated in detail in dedicated guides, this piece offers a concise overview of each, situating it within the broader framework. The emphasis throughout is on the coherence of negligence as a single, principled cause of action, and on the doctrinal tensions and policy considerations that continue to shape its evolution.

Historical development

Before Donoghue: the pre-modern landscape

The tort of negligence, as it is now understood, did not exist in English law before the twentieth century. This is not to say that careless conduct went unremedied – it did not – but rather that liability for carelessness was not organised under a single, general principle. Instead, it was dispersed across a patchwork of specific, often overlapping, categories.

The oldest relevant strand was the action on the case, which by the medieval period permitted claims for damage caused by the defendant’s positive act where no trespass lay. Liability for misfeasance by those exercising a common calling – innkeepers, carriers, surgeons, farriers – was well established by the fourteenth century. These obligations were essentially status-based: a person who held himself out as practising a trade or profession was expected to exercise competence. The duty arose not from any general principle of care but from the relationship created by the undertaking itself.

A crucial early development was the recognition that an action could lie for negligent performance of a voluntary undertaking. In Coggs v Bernard (1703) 2 Ld Raym 909, the Court of King’s Bench held that a gratuitous bailee who undertook to transport goods safely was liable for damage caused by his negligent handling. Chief Justice Holt’s classification of bailments in that case was deeply influential, but the duty it recognised remained tethered to the specific relationship of bailment, not to any broader concept of negligent conduct.

Through the eighteenth and nineteenth centuries, liability for carelessness expanded incrementally. Highway cases, employer liability cases, and cases involving the supply of dangerous goods each developed their own rules. In Vaughan v Menlove (1837) 3 Bing NC 468, the Court of Common Pleas established the objective standard of care – the “prudent” or “reasonable man” – in the context of a fire that spread from a badly constructed hayrick. The defendant’s argument that the court should judge him by reference to his own (limited) intelligence was rejected. This was a pivotal moment, establishing that the standard against which conduct is measured in negligence is external and impersonal. But even Vaughan v Menlove did not articulate a general principle of negligence; it concerned a particular category of harm (fire damage to neighbouring property) within a recognised factual setting.

By the late nineteenth century, the landscape was characterised by what Professor Percy Winfield would later describe as a series of “pigeon-holes”: discrete categories in which a duty of care had been established by precedent, with no unifying principle connecting them. Whether a duty existed in any novel situation could be answered only by analogy with recognised categories. The leading textbook of the era, Pollock’s The Law of Torts (first published 1887), attempted a synthesis, but the case law remained fragmented. The question that would dominate the twentieth century — whether English law recognised a general duty to take reasonable care to avoid foreseeable harm – had not yet been answered.

Donoghue v Stevenson and the birth of the general principle

The transformation came with Donoghue v Stevenson [1932] AC 562. The facts are well known. Mrs Donoghue consumed part of a bottle of ginger beer manufactured by Stevenson and purchased by her friend. The bottle allegedly contained the decomposed remains of a snail. She fell ill. Because she had not purchased the ginger beer herself, she had no contractual claim against the manufacturer. The question for the House of Lords was whether the manufacturer owed her a duty of care in tort.

By a majority of three to two, the House held that he did. The speech of Lord Atkin is one of the most celebrated in the common law. Drawing on the biblical injunction to love one’s neighbour, he formulated what became known as the “neighbour principle”:

“You must take reasonable care to avoid acts or omissions which you can reasonably foresee would be likely to injure your neighbour. Who, then, in law, is my neighbour? The answer seems to be – persons who are so closely and directly affected by my act that I ought reasonably to have them in contemplation as being so affected when I am directing my mind to the acts or omissions which are called in question.”

The significance of this passage cannot be overstated. For the first time, the House of Lords articulated a general principle from which the existence of a duty of care could be derived in novel situations, rather than requiring the claimant to fit his case into an established category. The decision did not abolish the existing categories; rather, it supplied a unifying rationale that explained them and permitted principled extension to new facts.

It is important, however, not to overstate the immediate effect of Donoghue v Stevenson. The decision was confined on its facts to the liability of a manufacturer to the ultimate consumer of a defective product. It was controversial at the time – Lord Buckmaster’s dissent is forceful – and its broader implications were worked out only gradually over the following decades. The neighbour principle was not treated as a universal test for the existence of a duty of care; rather, it operated as a guiding principle to be applied incrementally.

The period of expansion

The decades following Donoghue v Stevenson saw a marked expansion of negligence liability. Courts applied the neighbour principle to an increasingly wide range of factual situations. Liability was extended to local authorities for negligent building inspection (Dutton v Bognor Regis Urban District Council [1972] 1 QB 373), to solicitors for the negligent preparation of wills affecting intended beneficiaries (Ross v Caunters [1980] Ch 297), and to a wide range of professional advisers.

A particularly significant development was the recognition of liability for negligent misstatement causing pure economic loss. In Hedley Byrne & Co Ltd v Heller & Partners Ltd [1964] AC 465, the House of Lords held that a party who assumed responsibility for the accuracy of a statement, knowing that it would be relied upon, could owe a duty of care to the recipient even in the absence of a contractual relationship. The decision was notable both for extending negligence into the domain of pure economic loss – traditionally the preserve of contract – and for grounding the duty in the concept of an assumption of responsibility, a doctrinal basis that would prove of enduring importance.

The most ambitious attempt to formulate a single, comprehensive test for the existence of a duty of care came in Anns v Merton London Borough Council [1978] AC 728. Lord Wilberforce proposed a two-stage test. First, the court should ask whether there was a sufficient relationship of proximity between the parties, based on foreseeability of harm, such that a prima facie duty of care arose. Second, the court should consider whether there were any policy considerations that ought to negative, reduce, or limit the scope of the duty. The Anns test was remarkably expansive: it effectively created a presumption in favour of a duty of care wherever harm was foreseeable, rebuttable only by policy.

The Anns test was applied widely but attracted growing criticism. Its breadth was thought to expose defendants – particularly public authorities – to indeterminate liability. The policy stage was criticised as unprincipled and subjective. In a series of decisions through the 1980s, the courts retreated. Anns itself was overruled on its facts by Murphy v Brentwood District Council [1991] 1 AC 398, in which the House of Lords held that a local authority owed no duty of care in respect of defective buildings causing pure economic loss.

The Caparo retrenchment

The modern framework for determining the existence of a duty of care was established in Caparo Industries plc v Dickman [1990] 2 AC 605. The House of Lords rejected the Anns two-stage approach and replaced it with a threefold test. A duty of care arises where:

1. the harm to the claimant was reasonably foreseeable;
2. there was a relationship of sufficient proximity between the claimant and the defendant; and
3. it is fair, just and reasonable to impose a duty.

Lord Bridge emphasised that the law should develop incrementally, by analogy with established categories, rather than by application of a single abstract principle. The Caparo test is not a mechanical formula but a framework for structured judicial reasoning, within which considerations of policy and principle can be openly articulated. Its third limb – the requirement that a duty be fair, just and reasonable – has been criticised for introducing an overtly policy-based element into what is ostensibly a question of legal principle, but it has also been praised for making transparent the value judgments that the courts inevitably make.

The Caparo test has been applied and refined in numerous subsequent decisions. In Robinson v Chief Constable of West Yorkshire Police [2018] UKSC 4, the Supreme Court clarified the relationship between the Caparo test and established categories of duty. Lord Reed, giving the leading judgment, explained that the Caparo test is not a universal prerequisite that must be applied in every case. Where an established principle or category of duty covers the facts, the court should apply it directly. The Caparo test is engaged only where the court is asked to recognise a duty of care in a novel situation – that is, one not covered by existing authority. This restatement was doctrinally significant: it confirmed that the development of the duty of care proceeds primarily by incremental analogy, with the Caparo test serving as a framework for genuinely novel cases rather than a threshold to be crossed in every claim.

The elements of negligence

The tort of negligence comprises four essential elements, each of which the claimant must prove on the balance of probabilities. These elements are conceptually distinct, though in practice they frequently interact.

Duty of care

The first requirement is that the defendant owed the claimant a duty to take reasonable care. The duty of care is the gatekeeper of negligence liability: it determines not whether the defendant was careless, but whether the law recognises an obligation of carefulness towards the particular claimant in respect of the particular type of harm suffered.

The general framework for establishing a duty of care is the Caparo threefold test, as clarified by Robinson. But the duty of care is not a monolithic concept. Different analytical approaches have been developed for different contexts. In cases involving an assumption of responsibility – particularly those involving negligent misstatement or the provision of professional services — the courts apply the test derived from Hedley Byrne, as elaborated in Henderson v Merrett Syndicates Ltd [1995] 2 AC 145 and Spring v Guardian Assurance plc [1995] 2 AC 296. In these cases, the focus is on whether the defendant voluntarily assumed responsibility for the task or advice in question, and whether the claimant reasonably relied upon the defendant’s care and skill.

Several specific areas of the duty of care have generated particular difficulty and a substantial body of authority. These include the duty of care owed by public authorities (where considerations of justiciability, statutory discretion, and policy play a significant role), the duty in respect of pure economic loss (where the courts have historically been more restrictive than in cases of physical injury), omissions (where the general rule is that there is no duty to act, subject to important exceptions), and psychiatric injury (where the control mechanisms established in Alcock v Chief Constable of South Yorkshire Police [1992] 1 AC 310 continue to apply).

Breach of the standard of care

Once a duty of care is established, the claimant must show that the defendant breached it – that is, that the defendant’s conduct fell below the standard required by law. The standard is that of the reasonable person. This is an objective standard: the law does not ask whether this particular defendant did his best, but whether a reasonable person in the defendant’s position would have acted differently.

The locus classicus for the factors relevant to assessing breach is Bolton v Stone [1951] AC 850, in which the House of Lords held that a cricket club was not negligent when a batsman struck a ball out of the ground and injured a passer-by, because the probability of such an occurrence was extremely small. Lord Reid identified the key factors as: the likelihood of harm occurring, the severity of harm if it does occur, the cost and practicability of precautions, and the social utility of the defendant’s activity. These factors were applied in Latimer v AEC Ltd [1953] AC 643, where the House held that an employer was not required to close an entire factory to eliminate a residual risk of slipping on a wet floor, given the steps already taken and the disproportionate cost of closure.

Where the defendant exercises a particular profession or skill, the standard of care is that of the reasonably competent practitioner in that field. The seminal authority for professional negligence is Bolam v Friern Hospital Management Committee [1957] 1 WLR 582, in which McNair J directed the jury that a doctor is not negligent if he acts in accordance with a practice accepted as proper by a responsible body of medical opinion. The Bolam test was for many years treated as virtually conclusive: provided the defendant could point to a respectable body of professional support, a finding of negligence was difficult to sustain. This position was qualified by the House of Lords in Bolitho v City and Hackney Health Authority [1998] AC 232, which held that the professional practice relied upon must be capable of withstanding logical analysis. The court is not bound to accept expert opinion that is not logically defensible.

Causation

The claimant must prove that the defendant’s breach of duty caused the loss complained of. Causation in negligence operates at two levels: factual causation and legal causation.

Factual causation is generally determined by the “but for” test: the claimant must show that, but for the defendant’s negligence, the loss would not have occurred. This test was classically applied in Barnett v Chelsea and Kensington Hospital Management Committee [1969] 1 QB 428, where a hospital’s failure to examine a patient who had been poisoned was held not to be a cause of his death, because he would have died even if examined.

The “but for” test, while adequate for straightforward cases, encounters difficulty in cases of multiple sufficient causes, uncertain causation, and evidential gaps. The courts have developed significant modifications to address these situations. In Fairchild v Glenhaven Funeral Services Ltd [2002] UKHL 22, the House of Lords held that where a claimant had been negligently exposed to asbestos by multiple employers, and the medical evidence could not establish which employer’s exposure had caused his mesothelioma, it was sufficient to show that each defendant had materially increased the risk of harm. This departure from strict “but for” causation was described as exceptional and was closely confined to its particular factual context – though its precise limits were further explored in Barker v Corus UK Ltd [2006] UKHL 20 and subsequently modified by section 3 of the Compensation Act 2006.

Another important exception is the “material contribution” test, applied in Bailey v Ministry of Defence [2008] EWCA Civ 883, where the Court of Appeal held that where the claimant’s injury resulted from a combination of tortious and non-tortious causes, and the tortious cause made a material (that is, more than negligible) contribution to the injury, causation is established. The distinction between material contribution to injury and material contribution to risk remains doctrinally significant and not always easy to draw.

Legal causation is concerned with whether, assuming the breach was a factual cause of the loss, the chain of causation was broken by intervening events. A novus actus interveniens – whether an act of the claimant, a third party, or a natural event – may sever the causal link if it is of such a nature that it can fairly be regarded as the sole cause of the damage. The principles governing intervening causation are discussed in detail separately – see our novus actus interveniens guide.

Remoteness of damage

Even where the defendant’s breach is shown to have caused the claimant’s loss, the defendant is liable only for damage that is not too remote. The test for remoteness was established in Overseas Tankship (UK) Ltd v Morts Dock & Engineering Co Ltd (The Wagon Mound) (No. 1) [1961] AC 388, which replaced the earlier “direct consequence” test from Re Polemis and Furness, Withy & Co Ltd [1921] 3 KB 560. The Privy Council held that a defendant is liable only for damage of a kind that was reasonably foreseeable at the time of the breach.

The remoteness test is qualified by the “thin skull” rule (sometimes referred to as the “eggshell skull” rule), by which a defendant must take the claimant as he finds him. If the kind of damage suffered is foreseeable, the defendant is liable for its full extent even if the severity is unforeseeable by reason of the claimant’s pre-existing vulnerability. This principle was applied in Smith v Leech Brain & Co [1962] 2 QB 405, where a burn – itself a foreseeable consequence of the defendant’s negligence – triggered a pre-existing cancerous condition and the claimant’s death.

Remoteness and foreseeability thus perform different functions at different stages of the negligence inquiry: foreseeability is relevant to the existence of a duty of care, to the standard of care, and to the remoteness of damage, but the test is not applied identically at each stage.

Key areas of difficulty

Pure economic loss

One of the most contested areas in the law of negligence is liability for pure economic loss – that is, financial loss that is not consequential upon physical injury to person or property. The general rule, established in Spartan Steel & Alloys Ltd v Martin & Co (Contractors) Ltd [1973] QB 27 and reinforced in Murphy v Brentwood District Council [1991] 1 AC 398, is that pure economic loss is not recoverable in negligence. The justifications for this exclusionary rule are various: the risk of indeterminate liability to an indeterminate class, the availability of contractual allocation of risk, and the concern that tort should not undermine the structure of contractual relationships.

The principal exception to this exclusion is the Hedley Byrne principle, under which a duty of care in respect of pure economic loss may arise where the defendant assumes responsibility for a statement or service and the claimant reasonably relies upon it. This principle has been extended well beyond the original context of negligent misstatement. In Henderson v Merrett Syndicates Ltd [1995] 2 AC 145, the House of Lords applied the assumption of responsibility test to the provision of professional services, holding that Lloyd’s managing agents owed a duty of care in tort to Names on their syndicates. Lord Goff’s speech in Henderson is a key authority for the proposition that the assumption of responsibility concept provides a coherent basis for extending liability in this area, and that it can operate concurrently with contractual duties.

The boundaries of recovery for pure economic loss remain uncertain and are periodically tested. The distinction between “defective quality” loss (generally irrecoverable) and “consequential” loss (potentially recoverable) continues to generate litigation. The Supreme Court’s decision in Poole Borough Council v GN [2019] UKSC 25, while primarily concerned with the duty of care owed by a local authority, reaffirmed the general reluctance to impose liability for pure economic loss outside established categories.

Psychiatric injury

Liability for psychiatric injury – sometimes misleadingly termed “nervous shock” – has been shaped by policy concerns about the potential breadth of claims. The law draws a fundamental distinction between primary victims, who are directly involved in the tortious event or reasonably believe themselves to be in danger, and secondary victims, who suffer psychiatric harm as a result of witnessing injury to others.

For primary victims, the ordinary principles of negligence apply, and there is no requirement to show that psychiatric injury was foreseeable (Page v Smith [1996] AC 155, though this decision has been criticised and its status was questioned by the Supreme Court in Paul v Royal Wolverhampton NHS Trust [2024] UKSC 1).

For secondary victims, the restrictive control mechanisms established in Alcock v Chief Constable of South Yorkshire Police [1992] 1 AC 310 apply. The claimant must establish: (i) a close tie of love and affection with the primary victim; (ii) proximity in time and space to the accident or its immediate aftermath; and (iii) perception of the accident or its aftermath with his own unaided senses. In Paul v Royal Wolverhampton NHS Trust [2024] UKSC 1, the Supreme Court conducted a comprehensive review of the law relating to secondary victims of psychiatric injury. The court upheld the Alcock control mechanisms and declined to extend liability to cases where the horrifying event was separated from the negligent act by a significant period, confirming that where a claimant witnessed a medical crisis consequent upon an earlier act of clinical negligence, the relevant event for the purposes of the proximity requirement was the negligent act itself, not the later manifestation. The decision reaffirmed the principled but restrictive approach to secondary victim claims.

Omissions

The general rule in English negligence law is that there is no liability for a pure omission – a mere failure to act. This rule reflects a deeply embedded distinction in the common law between misfeasance (positive wrongdoing) and nonfeasance (a failure to confer a benefit or prevent harm). As Lord Hoffmann observed in Stovin v Wise [1996] AC 923, “there are sound reasons why omissions require different treatment from positive conduct.”

The distinction is, however, subject to important exceptions. A duty to act positively may arise where the defendant has created or is responsible for the source of danger (Goldman v Hargrave [1967] 1 AC 645), where the defendant has assumed responsibility for the claimant’s welfare (Barrett v Ministry of Defence [1995] 1 WLR 1217), where the parties are in a relationship that gives rise to a duty of protection (such as employer and employee), or where the defendant has undertaken to perform a task and the claimant has relied upon that undertaking. The limits of these exceptions continue to be explored, and the distinction between acts and omissions is itself often difficult to draw. In Michael v Chief Constable of South Wales Police [2015] UKSC 2, the Supreme Court held by a majority that the police owed no duty of care to a victim of domestic violence who had telephoned the emergency services but received no timely response, reaffirming the general principle that public authorities do not owe a common law duty to protect individuals from harm caused by third parties.

Public authority liability

The liability of public authorities in negligence has been a persistent source of difficulty. Public bodies exercise statutory functions, often involving the allocation of limited resources and the exercise of discretion, and the courts have been cautious about subjecting these functions to the ordinary principles of negligence. In X (Minors) v Bedfordshire County Council [1995] 2 AC 633, the House of Lords struck out claims by children alleging negligent failure by local authorities to protect them from abuse, holding that considerations of policy militated against the recognition of a duty of care.

This position was significantly revisited following the European Court of Human Rights’ decision in Z v United Kingdom [2001] 2 FLR 612, which held that the blanket striking out of such claims violated Article 6 of the European Convention on Human Rights. Subsequent domestic decisions have adopted a more nuanced approach. In Poole Borough Council v GN [2019] UKSC 25, the Supreme Court clarified that public authorities are generally subject to the same principles of negligence as private individuals. A public authority does not owe a duty of care merely by reason of exercising its statutory functions; the question is whether the particular facts give rise to a duty applying ordinary common law principles, including the general rule against liability for omissions.

Defences

Contributory negligence

At common law, contributory negligence operated as a complete defence: if the claimant’s own carelessness contributed to his loss, his claim failed entirely. This draconian rule was abolished by the Law Reform (Contributory Negligence) Act 1945, section 1(1) of which provides that where a person suffers damage as the result partly of his own fault and partly of the fault of another, the damages recoverable shall be reduced to such extent as the court thinks just and equitable having regard to the claimant’s share in the responsibility for the damage.

The apportionment of responsibility involves consideration of both the relative causative potency of each party’s conduct and the relative blameworthiness. In Froom v Butcher [1976] QB 286, the Court of Appeal established guideline reductions for failure to wear a seatbelt: typically 25 per cent where the injuries would have been entirely prevented, and 15 per cent where they would have been less severe.

Volenti non fit injuria

The defence of consent, expressed in the maxim volenti non fit injuria, provides a complete defence where the claimant freely and voluntarily assumed the risk of injury. The defence requires more than mere knowledge of the risk; the claimant must have consented to the risk of the defendant’s negligence. In ICI Ltd v Shatwell [1965] AC 656, the House of Lords applied the defence where two experienced shotfirers deliberately disregarded safety regulations. The defence is now of limited practical significance in many contexts, having been excluded by statute in employer liability cases (section 1 of the Law Reform (Personal Injuries) Act 1948) and restricted in road traffic cases (section 149 of the Road Traffic Act 1988).

Illegality

The defence of illegality (ex turpi causa non oritur actio) may bar a negligence claim where the claimant’s loss arises in the context of his own criminal conduct. The modern approach was authoritatively restated by the Supreme Court in Patel v Mirza [2016] UKSC 42, which adopted a multi-factorial approach focused on whether allowing the claim would be harmful to the integrity of the legal system. The application of this approach in the negligence context was further considered in Henderson v Dorset Healthcare University NHS Foundation Trust [2020] UKSC 43, where the Supreme Court held that a claimant detained under the Mental Health Act 1983 who had killed her mother during a psychotic episode could not recover damages in negligence from the NHS trust whose negligent treatment had allegedly caused her episode, because her claim was inseparable from her criminal act of manslaughter.

Limitation

A negligence claim must ordinarily be brought within the limitation period prescribed by the Limitation Act 1980. For personal injury claims, the primary limitation period is three years from the date on which the cause of action accrued or the date of the claimant’s knowledge, whichever is the later (section 11). The court retains a discretion under section 33 to disapply the primary limitation period where it would be equitable to do so. For other negligence claims – including property damage and pure economic loss – the limitation period is six years from the date of accrual (section 2). The running of time in cases of latent damage is governed by the Latent Damage Act 1986, which inserts sections 14A and 14B into the 1980 Act, providing a three-year period from the date of discoverability subject to a longstop of fifteen years.

Remedies

The primary remedy in negligence is an award of compensatory damages, the purpose of which is to place the claimant, so far as money can, in the position he would have been in had the tort not been committed (Livingstone v Rawyards Coal Co (1880) 5 App Cas 25). Damages are assessed once and for all at the date of trial, though in personal injury cases the court may make a periodical payments order under section 2 of the Damages Act 1996.

Damages in negligence are divided into general damages (for non-pecuniary losses such as pain, suffering, and loss of amenity) and special damages (for quantifiable financial losses such as lost earnings and the cost of care). The assessment of future losses involves a multiplier-multiplicand calculation, and the discount rate applied to lump-sum awards for future losses is set by the Lord Chancellor under section 1 of the Damages Act 1996 (as substituted by section 10 of the Civil Liability Act 2018).

Injunctive relief is available in negligence but is relatively uncommon, being most frequently sought in cases of continuing or anticipated tortious conduct such as nuisance overlapping with negligence. An injunction may be mandatory (requiring the defendant to take positive steps) or prohibitory (requiring the defendant to cease the offending conduct).

Negligence and statute

The relationship between negligence and statutory obligations is complex. A breach of statutory duty does not automatically give rise to a duty of care in negligence, nor does the existence of a statutory framework necessarily exclude the common law. The two regimes operate in parallel but on distinct foundations.

Historically, a breach of statutory duty could itself found a tort action – the tort of breach of statutory duty – where the statute was construed as conferring a private right of action. This tort is analytically distinct from negligence, though in practice the two are frequently pleaded together. The trend of modern authority has been to restrict the availability of the breach of statutory duty tort, particularly in the context of regulatory legislation. In X (Minors) v Bedfordshire and subsequent cases, the House of Lords held that the existence of a statutory scheme of regulation does not, without more, give rise to a common law duty of care mirroring the statutory obligations. The position is now governed by the general principles restated in Poole Borough Council v GN.

Where statute does impose specific duties – for example, the Occupiers’ Liability Acts 1957 and 1984, or the Consumer Protection Act 1987 (implementing strict liability for defective products) – these operate as self-contained statutory regimes that may supplement or, in some respects, modify the common law of negligence. The Occupiers’ Liability Act 1957, in particular, is best understood as a statutory codification of the duty of care owed by occupiers to lawful visitors, replacing the previous common law categories of invitee and licensee with a single “common duty of care” (section 2(2)).

Modern developments and continuing tensions

The law of negligence continues to develop, and several contemporary themes merit attention.

The incrementalist orthodoxy. 

The approach confirmed in Robinson  – that the law of negligence develops incrementally, by analogy with established categories, and that the Caparo test is reserved for genuinely novel situations – is now firmly established. This approach has the virtue of doctrinal stability and predictability, but it has been criticised for its conservatism and for making it difficult for claimants to succeed in cases that do not fit neatly within existing categories. The tension between principled development and pragmatic restraint is inherent in the structure of the Caparo test itself, and is unlikely to be resolved definitively.

The scope of duty. 

The concept of the “scope of duty” – the idea that a defendant’s duty extends only to the protection of the claimant from certain kinds of harm, and that the breach must fall within the scope of that duty – received its most thorough modern treatment in Khan v Meadows [2021] UKSC 21. The Supreme Court held that a GP who negligently failed to inform a patient of her carrier status for haemophilia was liable only for the consequences attributable to haemophilia, and not for the unrelated condition of autism with which her child was also born. Lord Burrows, giving the majority judgment, endorsed a six-stage framework previously articulated by Lord Hoffmann in South Australia Asset Management Corporation v York Montague Ltd [1997] AC 191 (the “SAAMCO” case), clarifying the distinction between “advice” cases (where the defendant is responsible for all foreseeable consequences of the transaction entered into in reliance on the advice) and “information” cases (where liability extends only to the consequences of the information being wrong). The Khan v Meadows decision is significant for its systematisation of the scope of duty concept and its integration of this concept into the mainstream analysis of negligence.

Psychiatric injury. 

As noted above, the Supreme Court’s decision in Paul v Royal Wolverhampton NHS Trust [2024] UKSC 1 has reaffirmed the Alcock control mechanisms for secondary victim claims. The decision attracted scrutiny from those who regard the current restrictions as arbitrary and out of step with medical understanding of psychiatric harm, but the court was clear that any reform to the secondary victim framework is a matter for Parliament rather than judicial development.

Clinical negligence. Clinical negligence remains one of the most significant areas of negligence litigation in practice. The Supreme Court’s decision in Montgomery v Lanarkshire Health Board [2015] UKSC 11 marked a decisive shift in the standard of disclosure required of medical practitioners, holding that a doctor is under a duty to take reasonable care to ensure that a patient is aware of any material risks involved in a proposed treatment and of any reasonable alternative treatments. A risk is material if a reasonable person in the patient’s position would be likely to attach significance to it. Montgomery is notable for its departure from the paternalism of the Bolam/Sidaway approach to informed consent, reflecting a broader movement towards patient autonomy.

Conclusion

Negligence in English law is not a static doctrine but a continuing exercise in the reconciliation of competing values: individual accountability and protection from harm; certainty and flexibility; the correction of private wrongs and the allocation of loss across society. From its origins in the fragmented, status-based obligations of the medieval common law, through the foundational principle articulated in Donoghue v Stevenson, the expansionist ambition of Anns, the cautious retrenchment of Caparo, and the incrementalist orthodoxy reaffirmed in Robinson, the tort of negligence has been shaped by an ongoing dialogue between the courts, the legislature, and the academy.

The structure of the modern tort – duty, breach, causation, remoteness – provides a framework of considerable analytical power. But the framework is not self-executing. Each element involves the application of evaluative judgments, and the boundaries of negligence are set not by logical deduction alone but by the courts’ assessment of what is fair, workable, and consistent with the broader values of the legal system. The decisions of recent years – Khan v Meadows on scope of duty, Paul on secondary victim claims, Montgomery on informed consent, Poole on public authority liability – confirm that the law of negligence remains a site of active development, shaped by new facts, new arguments, and evolving social expectations.

For the practitioner, the message is that negligence claims demand close attention to the specific legal principles governing each element, to the applicable body of authority, and to the policy considerations that inform the courts’ reasoning. For the student and researcher, negligence offers a uniquely rich case study in the common law method: the incremental, case-by-case development of principle through the resolution of individual disputes, constrained but not determined by precedent, and animated throughout by the effort to achieve justice between the parties before the court.
