When something goes wrong in the care a doctor provides, the question most patients ask is: was that negligence, or just an unfortunate outcome? The two are not the same in law, and understanding the distinction is the starting point for anyone considering a claim. This guide explains what doctor negligence is, what you need to prove, the time limits that apply, and how the claims process works in England and Wales.
Nothing here is legal advice. If you believe your doctor's care fell below an acceptable standard and caused you harm, speaking to a specialist solicitor as early as possible protects your position on evidence and time limits.
What is doctor negligence?
Doctor negligence (also called clinical or medical negligence) is a failure by a doctor to provide the standard of care that a reasonably competent doctor in the same specialty would have provided in the same circumstances, where that failure causes harm to the patient. Three things must all be true: a duty of care existed, the doctor breached that duty, and the breach caused the harm you suffered.
The key distinction is between a poor outcome and a negligent act. Medicine involves risk and uncertainty. A doctor who follows an accepted course of treatment and still produces a bad result has not necessarily been negligent. What matters is not the outcome but the standard of care that was actually delivered.
The legal benchmark comes from Bolam v Friern Hospital Management Committee [1957] 1 WLR 582, known as the Bolam test. A doctor is not negligent if they acted in accordance with a practice accepted as proper by a responsible body of medical opinion in the relevant specialty. Put plainly: the question is whether a competent body of doctors in that field would have done the same thing. If the answer is yes, the claim for breach of duty will not succeed, regardless of how serious the outcome was.
Is "medical malpractice" the same thing?
In UK law, the correct term is clinical negligence or medical negligence. "Medical malpractice" is a US legal term, but it describes the same concept: a healthcare professional's failure to meet the expected standard of care, causing harm to a patient. There is no separate doctrine of "malpractice" in English or Welsh law.
If you arrived here searching for medical malpractice, you are in the right place. The legal tests, the process, and the remedies available in England and Wales are all governed by the law of clinical negligence, and the information on this site applies directly to your situation.
What standard of care does a doctor owe you?
Every registered doctor in the UK owes you a duty to provide a good standard of care. The Good Medical Practice guidance published by the General Medical Council (GMC) sets out what that means in practice: doctors must work within their competence, keep their knowledge and skills up to date, listen to patients, and make the care of patients their first concern. This guidance carries statutory weight under the Medical Act 1983 and is the benchmark against which the GMC assesses a doctor's conduct and fitness to practise.
The Bolam test sets the legal floor for treatment decisions. However, Bolitho v City and Hackney Health Authority [1997] UKHL 46 added an important qualification: the responsible body of medical opinion a doctor relies on must be capable of withstanding logical analysis. A court is not required to accept expert evidence uncritically. If a medical opinion is internally inconsistent, or fails to properly weigh the risks and benefits of a decision, the court can reject it even if a genuine body of doctors holds that view.
For consent and risk disclosure, the standard is different and more demanding. Following Montgomery v Lanarkshire Health Board [2015] UKSC 11, a doctor must tell you about any risk that you, as a reasonable patient in your position, would consider significant when deciding whether to proceed. The Bolam test does not apply to this question. Whether a risk was material enough to require disclosure is assessed from your perspective, not from the perspective of what most doctors would have told you. A doctor who proceeds with a procedure without disclosing a significant risk can be found negligent in relation to the consequences of that risk materialising, even if the procedure itself was carried out to a competent standard.
Your patient rights include access to all medical records held about you, which form the evidential foundation of any negligence claim.
Common examples of doctor negligence
The most common types of doctor negligence involve delayed or missed diagnosis, failure to refer, and prescription errors. These categories account for the majority of claims under the GP indemnity scheme (the Clinical Negligence Scheme for General Practice, or CNSGP), the state-backed indemnity scheme that NHS Resolution has operated for GP claims since April 2019.
Delayed or missed diagnosis. A GP who fails to recognise the symptoms of a serious condition, or who diagnoses one condition when the patient has another, may be negligent if a competent GP faced with the same presentation would have reached the correct diagnosis or arranged further investigation. Missed cancer diagnoses, delayed recognition of sepsis, and failure to identify stroke symptoms are among the most frequently litigated examples. The issue is not whether the correct diagnosis was difficult to reach, but whether a competent GP would have reached it, or at minimum referred for specialist assessment.
Failure to refer to a specialist. GPs are generalists. They are not expected to diagnose every condition themselves, but they are expected to refer when the clinical picture warrants it. A failure to make a timely referral for further investigation, where a competent GP would have referred, is one of the most common bases for a doctor negligence claim. This is particularly relevant in cases involving symptoms that could indicate cancer, where early referral under the two-week wait pathway can determine the stage at which a diagnosis is made.
Prescription and medication errors. Prescribing the wrong drug, an incorrect dose, or a medication contraindicated with something a patient is already taking can cause significant and sometimes irreversible harm. These errors are generally well documented in prescription records and clinical notes, making them among the more straightforward types of negligence to evidence. Common examples include failure to check for drug interactions, prescribing adult doses to children, and continuing a prescription despite recorded contraindications.
Failure to obtain informed consent. Under the Montgomery standard, a doctor who proceeds with a procedure without disclosing a risk that a reasonable patient would have wanted to know about may be liable for the consequences of that risk materialising, even if the procedure was carried out competently. This applies to elective procedures, diagnostic interventions, and treatments with known serious side effects.
Surgical and procedural errors. Wrong-site surgery, retained surgical instruments, and avoidable perforations during procedures are examples of negligence that can arise in both primary and secondary care. These are covered in more detail in our surgical negligence guidance.
What you need to prove
A doctor negligence claim requires four elements. All four must be established for a claim to succeed.
Duty of care. A doctor owes you a duty of care once a doctor-patient relationship exists. This is rarely disputed: it arises as soon as a doctor agrees to assess or treat you, whether in a GP surgery, a hospital clinic, or a private practice.
Breach of duty. The doctor's conduct fell below the Bolam standard. This is the central factual question in most claims, and it requires independent expert evidence from a doctor practising in the relevant specialty. The expert reviews the medical records and gives an opinion on whether the care provided fell below the standard of a competent practitioner in that field.
Causation. The breach caused the harm you suffered. Under the "but for" test established in Barnett v Chelsea and Kensington Hospital [1969] 1 QB 428, you must show that, but for the doctor's negligence, the harm would not have occurred (or would have been less severe). Causation is often the hardest element to establish, particularly in delayed diagnosis cases where the question is whether earlier treatment would have changed the outcome. In cancer cases, for example, this requires expert oncological evidence about the difference in prognosis between the stage at which the cancer was actually diagnosed and the stage at which it would have been diagnosed had a timely referral been made.
Harm. You suffered a recognised injury, financial loss, or a material worsening of a condition as a result. A negligent act that causes no quantifiable harm does not give rise to a claim for compensation, though other remedies (such as an NHS complaint) remain available.
The full claims process, from securing your records to the Letter of Claim and NHS Resolution's response, is covered in detail elsewhere on this site.
How long do you have to make a doctor negligence claim?
You generally have three years to bring a doctor negligence claim. Under the Limitation Act 1980, the three-year period runs from the date of the negligent act or the date of knowledge, whichever is later.
The date of knowledge is the date you first knew, or could reasonably have known, that the harm you suffered may have been caused by a doctor's negligence. For conditions that develop gradually, or where the connection between a doctor's failure and the eventual harm is not immediately apparent, the clock can start significantly later than the date of the original treatment. This exception is particularly relevant in delayed diagnosis cases where the link between an earlier failure and a later, more serious diagnosis only becomes clear years after the event.
Children are protected by a separate rule: the three-year period does not begin until they turn 18. An adult who lacks the mental capacity to conduct legal proceedings is protected for as long as that incapacity continues. Where a patient has died, the three-year period runs from the date of death or the date a relative first had knowledge that negligence may have been a cause.
Acting promptly is advisable. Medical records become more difficult to obtain and interpret as time passes, and the recollection of treating clinicians fades. An initial assessment is free and commits you to nothing.
How is a doctor negligence claim funded?
The standard funding arrangement for a doctor negligence claim is a Conditional Fee Agreement (CFA), commonly known as no win no fee. Under a CFA, you pay nothing upfront. If the claim is unsuccessful, you owe your solicitor nothing for their time.
If the claim succeeds, a success fee of up to 25% of your past losses and general damages is deducted from the award. This cap is set by the CFA Order 2013. Your future losses, including ongoing care costs and earnings you will lose going forward, are fully protected by law and cannot be reduced by the success fee.
After the event (ATE) insurance is typically arranged to cover the cost of medical expert reports and other disbursements in the event the claim fails. Qualified One-way Costs Shifting (QOCS) provides a further layer of protection: in most circumstances, if a claim is unsuccessful, you cannot be ordered to pay the defendant's legal costs.
For a plain-English explanation of what no win no fee means in practice, including worked examples of how the success fee affects the final figure you receive, see the CFA funding guide on this site.
