Medical negligence claims in the UK let you recover compensation when substandard treatment by a healthcare provider caused you injury, and in most cases you have three years from either the negligent treatment or the date you realised it had harmed you to start court proceedings. The claim can be brought against NHS trusts or private practitioners, must prove both a breach of the standard of care and a causal link to your injury, and covers pain and suffering alongside financial losses such as lost earnings and care costs. Different time limits apply to children, people lacking mental capacity, and fatal cases.
What You Have to Prove
A clinical negligence claim stands on three legs: the healthcare provider owed you a duty of care, they breached it by giving substandard treatment, and that breach caused your injury. The duty of care arises the moment a practitioner accepts you for treatment or consultation, and it applies the same way in NHS hospitals and private clinics.
Whether the care fell below standard is judged against the Bolam test, from the 1957 case of Bolam v Friern Hospital Management Committee. The question is whether the doctor acted in line with a practice that a responsible body of professionals skilled in that field would accept as proper. If a competent group of peers would have done the same thing, there is no breach, even where other doctors might have taken a different approach.
The House of Lords sharpened this in Bolitho v City and Hackney Health Authority in 1998. A court can reject a body of medical opinion, even one held by genuine experts, if the opinion cannot withstand logical analysis. A defendant cannot simply line up supportive experts and win automatically.
Consent was reshaped by the Supreme Court in Montgomery v Lanarkshire Health Board in 2015. Doctors must now tell you about any risk that a reasonable person in your position would consider significant, and about any reasonable alternatives. Failing to do so can amount to negligence even when the treatment itself was carried out competently.
Causation and the Standard of Proof
Showing the treatment was substandard is only half the task. You also have to prove causation using the “but for” test: would you have avoided the injury but for the negligent treatment? If the harm would have happened anyway, the claim fails here.
This is where many claims come unstuck. Patients are usually already unwell when they seek treatment, so separating the natural course of an existing condition from damage caused by the error takes detailed medical analysis. A delayed cancer diagnosis, for instance, needs evidence that earlier treatment would have changed the outcome, not just that the delay was careless.
Both breach and causation must be established on the balance of probabilities: more likely than not. That is a lower bar than the criminal standard, but it still demands solid expert medical evidence on each point.
Time Limits for Filing a Claim
Under Section 11 of the Limitation Act 1980, you generally have three years to issue court proceedings.1Legislation.gov.uk. Limitation Act 1980 – Section 11 The clock runs from whichever is later: the date of the negligence, or the date you first knew (or should reasonably have known) that your injury was linked to the treatment. The date-of-knowledge rule matters because some injuries only become apparent months or years after the event.
Different rules apply to children and people who lack mental capacity. Under Section 28 of the Limitation Act 1980, the three-year period does not start while a person is “under a disability,” which covers minors and anyone lacking capacity within the meaning of the Mental Capacity Act 2005.2Legislation.gov.uk. Limitation Act 1980 For a child, the three-year clock only starts on their 18th birthday, giving them until age 21. For someone who permanently lacks capacity, there is no time limit at all, and a litigation friend can bring the claim on their behalf at any point.
Where a patient dies as a result of negligence, the personal representative has three years from the date of death or from the date they first had knowledge of the claim, whichever is later.1Legislation.gov.uk. Limitation Act 1980 – Section 11
Even after the three years have run, courts have discretion under Section 33 of the Limitation Act 1980 to let a late claim proceed if they consider it fair. Judges look at the reasons for the delay, how it has affected the evidence, and whether the defendant can still mount a proper defence. The discretion exists, but relying on it is risky. Extensions are granted sparingly, and the longer the delay, the harder the argument.
Getting Your Medical Records
Your medical records are the foundation of a claim. Under the UK General Data Protection Regulation and the Data Protection Act 2018, you can request all health information held about you through a subject access request.3UK Parliament. Accessing Health Records The healthcare provider must respond within one month and generally cannot charge a fee.4Information Commissioner’s Office. Health Information
If the patient has died, the Access to Health Records Act 1990 provides a separate route. Personal representatives and anyone with a claim arising from the death can apply for access.5Legislation.gov.uk. Access to Health Records Act 1990 Those without personal representative status are generally limited to information directly relevant to the claim.
Alongside the formal records, keep a diary of symptoms, pain levels, and the way the injury affects your day-to-day life. A contemporaneous account carries real weight later. Statements from family members who saw your care or its aftermath also help.
The Pre-Action Protocol
Before any court papers are issued, clinical negligence claims in England and Wales must follow the Pre-Action Protocol for the Resolution of Clinical Disputes.6Justice UK. Pre-Action Protocol for the Resolution of Clinical Disputes It is designed to encourage early disclosure and settlement.
The process starts with a Letter of Claim sent to the defendant, usually the relevant NHS Trust or, for private treatment, the practitioner’s indemnity insurer. The letter must summarise the facts, describe the alleged negligence, outline your injuries and current condition, indicate the financial losses, confirm how the claim is being funded, and identify any expert evidence already obtained.
The defendant has 14 days to acknowledge the letter and four months to investigate and provide a detailed Letter of Response. That response must say whether liability is admitted or denied, address the specific allegations, and identify any expert evidence relied on. Court proceedings should not be issued until the four months have passed.
For NHS claims, the defence is handled by NHS Resolution, a government body that manages clinical negligence litigation for NHS Trusts. If liability is admitted, settlement talks begin. If it is denied, you must decide whether to issue proceedings. Many cases go through mediation or other alternative dispute resolution before reaching a judge.
How Compensation Is Calculated
Compensation splits into two categories: general damages and special damages.
General Damages
General damages compensate for pain, suffering, and “loss of amenity,” meaning the ways the injury has reduced your ability to enjoy life. If you can no longer play with your children, exercise, or carry out activities that were part of your routine, those losses have a monetary value.
Solicitors and courts assess general damages using the Judicial College Guidelines for the Assessment of General Damages in Personal Injury Cases, which sets financial brackets for different injury types and severities. A minor soft tissue injury sits far below a permanent spinal cord injury. The specific figure within any bracket depends on your individual circumstances.
Special Damages
Special damages cover the quantifiable financial losses flowing from the injury: lost earnings past and future, private medical treatment and rehabilitation, professional care at home, travel to appointments, equipment, and home modifications. Each head must be documented and evidenced. In serious cases, special damages often dwarf general damages.
Periodical Payment Orders
For catastrophic injuries like cerebral palsy or severe brain damage, a single lump sum can run out if the claimant lives longer than predicted, and families sometimes restrict spending on care out of fear of depleting the fund. Courts can order periodical payments instead of, or alongside, a lump sum. These payments are usually index-linked to protect against inflation in care costs, continue for the claimant’s lifetime, and stop on death. Stepped orders can also increase payments at set future dates to match expected changes in care needs.
Fatal Negligence Claims
Where negligence causes or contributes to a patient’s death, the family can bring a claim under the Fatal Accidents Act 1976. The Act provides a fixed statutory bereavement award, currently £15,120. Only certain family members can claim it: the spouse, civil partner, or cohabiting partner of the deceased (if they lived together for at least two years), and the parents of an unmarried minor child.7Legislation.gov.uk. Fatal Accidents Act 1976 – Section 1A Dependants can also claim for financial support they have lost, including income the deceased would have provided and the value of services they performed for the household.
Many fatal cases involve a coroner’s inquest first. A coroner cannot make findings of civil or criminal liability against a named individual.8Courts and Tribunals Judiciary. Chapter 15 – Conclusions But factual findings recorded at an inquest, including findings about shortcomings in care, can form part of the evidence in a later negligence claim. A conclusion of accidental death does not block a civil claim.
Paying for a Claim
Several funding routes exist so the cost does not fall on you upfront.
Conditional Fee Agreements
The most common arrangement is a Conditional Fee Agreement, widely known as no win, no fee. Your solicitor charges nothing if the claim fails. If you win, they take a success fee as a percentage of your compensation. Under the Legal Aid, Sentencing and Punishment of Offenders Act 2012, the success fee is capped at 25% of damages awarded for pain, suffering, loss of amenity, and past financial losses.9Legislation.gov.uk. Legal Aid, Sentencing and Punishment of Offenders Act 2012 – Section 44 Future losses, such as ongoing care costs, are excluded from that calculation, which matters in high-value claims.
Qualified One-Way Costs Shifting
Since April 2013, clinical negligence claimants benefit from qualified one-way costs shifting under Part 44 of the Civil Procedure Rules.10Justice UK. Part 44 – General Rules About Costs QOCS means that if you lose, the defendant generally cannot enforce a costs order against you. You can recover costs from them if you win; they cannot recover from you if you lose.
The protection is not absolute. You lose it if your claim is found to be fundamentally dishonest, if it is struck out as an abuse of process, or if your conduct obstructs the fair handling of proceedings. Discontinuing after the defendant has run up costs can also expose you. For a genuine claim pursued in good faith, though, QOCS gives robust cover.
After the Event Insurance
Even with QOCS, you can still be liable for disbursements like expert report fees if the case is lost. After the Event insurance covers those expenses. The premium is usually payable only on a successful outcome and comes out of the settlement, so nothing is paid upfront. If the case fails, the policy covers the costs. Solicitors running clinical negligence cases on a CFA will normally arrange ATE insurance as part of the funding package.
Legal Aid
Legal aid for clinical negligence is now very limited. It is only available for claims involving neurological injuries to babies that occurred during pregnancy, birth, or within eight weeks of birth, where the child was born at or after 37 weeks’ gestation. For every other type of clinical negligence claim, legal aid is not an option. Check any existing home or motor insurance policies for Legal Expenses Insurance before signing a CFA, because existing cover might reduce your overall cost.
Fixed Recoverable Costs for Lower Value Claims
Since October 2024, clinical negligence claims valued between £1,501 and £25,000 fall under the Lower Damages Fixed Recoverable Costs scheme.11GOV.UK. Fixed Recoverable Costs in Lower Damages Clinical Negligence Claims – Government Response The scheme caps the legal costs recoverable from the losing side. Expert report fees and ATE premiums remain recoverable outside the fixed costs, as do certain court fees in specific circumstances. If your claim is likely to sit in this range, ask your solicitor early how the scheme affects the economics of your case, because reduced recoverable costs may influence which firms are willing to take it on.
