GP Negligence Claims UK - Missed Diagnosis, Failure to Refer, Prescription Errors

GPs are the front door of the NHS. They see around 300 million consultations a year - by far the highest-volume contact most patients have with healthcare. When something goes wrong at the GP level - a cancer red flag missed, a referral that wasn't made, a medication error that caused harm - the consequences can be serious, especially because patients trust their GP to notice what they wouldn't notice themselves.

This page explains how GP negligence claims work in the UK: the common categories (missed diagnosis, failure to refer, prescription errors, failure to act on results, safety-netting failures), who you claim against, what you might receive, and the deadlines that apply. Every case we take on is on a no win, no fee basis.

What counts as GP negligence?

GP negligence is a type of clinical negligence. It succeeds where two things are proved (the same framework as any other medical claim - see the full explanation on our medical negligence pillar):

  • Breach of duty - the GP's conduct fell below the standard of a responsible body of competent general-practice opinion (Bolam / Bolitho), qualified by the logically-defensible test.

Most GP claims succeed on breach fairly readily - the Royal College of General Practitioners and NICE guidelines provide clear benchmarks for competent practice. The harder fight is often on causation: whether competent GP care would have led to a materially different outcome. This is the Gregg v Scott [2005] UKHL 2 'loss of chance' issue that affects many missed-diagnosis claims.

Who is the claim against?

Most UK GP practices operate as partnerships or limited companies contracted to the NHS, and most hold professional indemnity through NHS Resolution's Clinical Negligence Scheme for General Practice (CNSGP) for England-based NHS work, NHS Resolution equivalents in Wales and Scotland, or via private indemnifiers (the Medical Defence Union, Medical Protection Society, or commercial insurers).

You are not claiming against your GP's personal bank account. You are claiming against an indemnity scheme. You can continue to be registered with the same practice, and see the same GP, during and after a claim - most claimants do.

The common types of GP negligence

Missed or delayed diagnosis

The single largest category. Common missed diagnoses at GP level include: cancers (breast, bowel, lung, prostate, melanoma, ovarian, cervical), sepsis, meningitis, stroke, heart attack, DVT, ectopic pregnancy, appendicitis, diabetic ketoacidosis in children, and brain haemorrhage. Breach is often measured against NICE NG12 (suspected cancer recognition and referral) and condition-specific NICE guidelines. For the full misdiagnosis framework see misdiagnosis claims.

Failure to refer

Red-flag symptoms present, and the GP either fails to refer at all, refers via the wrong pathway, or fails to meet the urgency required (two-week-wait, urgent referral, suspected cancer pathway). The referral itself is fundamental - patients cannot self-refer for most specialist NHS care, so a missed referral has real consequences.

Prescription errors

Wrong drug, wrong dose, wrong route, missed allergy, missed interaction, repeat-prescription issued without review, overdose warning ignored, failure to check INR for warfarin, failure to monitor for known side-effects. Medication errors in primary care are well-documented and frequently cause harm that could have been avoided.

Failure to act on test results

The blood test that showed a red flag; the chest X-ray with an incidental finding; the pathology result that wasn't filed. A classic systems failure where the practice's results-handling process has a gap.

Safety-netting failures

Where a GP advised 'come back if it gets worse' but didn't specify what 'worse' would mean or when to return, or where a follow-up appointment should have been booked and wasn't. A growing area - NICE and RCGP guidance increasingly require specific, documented safety-netting advice.

Home visit failings

Declining a home visit where one was indicated, inadequate assessment during a home visit, or failing to escalate a deteriorating patient at home.

Where a GP recommended a treatment or procedure (e.g. in minor surgery performed in-practice, long-term contraception, or medication with significant side-effects) without adequately discussing material risks and reasonable alternatives. Under Montgomery v Lanarkshire Health Board [2015] UKSC 11, the consent standard is what would be material to a reasonable patient in your position.

The GP-specific evidence chain

GP claims depend heavily on the practice's own records, which are usually far more detailed than patients realise. A specialist solicitor will typically request:

  • Full GP patient record - including consultation notes, letters in and out, prescription history, test results and referrals.

Where the claim is against an out-of-hours or walk-in service, the provider's own clinical records and phone-triage recordings are crucial.

How much compensation could you receive?

Every GP negligence award is built from general damages (the avoidable injury, under the JCG 17th edition) and special damages (financial losses). The range is very wide - from low five figures for a recoverable drug-error injury to seven figures for a life-changing missed diagnosis. Representative general-damages ranges for GP-associated injuries:

  • Severe brain injury (missed stroke, missed sepsis): ~£344,150 - £493,000

In fatal cases, the estate and dependents can claim under the Law Reform (Miscellaneous Provisions) Act 1934 and Fatal Accidents Act 1976, with a statutory bereavement award of £15,120 for deaths on or after 1 May 2020. For the full valuation approach see how much compensation.

The GP negligence claim process

  1. Free eligibility call - specialist takes the account, identifies the defendant, flags the time limit.

Typical timescales: 2-4 years. Serious permanent-injury cases longer - settlement held until prognosis stabilises.

Time limits for GP negligence

Three years from the negligent act or the 'date of knowledge' under s.14 Limitation Act 1980 - which is when you first knew (or should have known) that the injury was significant and caused by the treatment. Many GP claims are brought on a 'date of knowledge' basis because the harm only becomes apparent after a later diagnosis. Children have until three years after their 18th birthday; protected parties have no limit while capacity is absent. See time limits.

How is it funded? No win, no fee

Every GP negligence claim we handle is run on a Conditional Fee Agreement. No upfront fees. If the claim wins, the success fee is capped at 25% of general damages and past losses; future losses sit outside the cap. If it loses, you pay nothing (subject to CFA and ATE terms). See no win no fee explained.

Can I still see the same GP during the claim?

Yes. A patient's right to stay registered with their GP is protected. A GP can only remove a patient from their list in narrow circumstances (e.g. violence, irreconcilable breakdown in the doctor-patient relationship), and 'you're suing me' is not on the list. The claim is defended by the practice's indemnifier, not by the GP personally.

Many claimants prefer to switch practices after a serious missed diagnosis - that's a personal choice, not a legal requirement.

Frequently asked questions

No. A civil claim and a practice complaint (or PHSO complaint) are independent. You can run both in parallel, or just the claim. The complaint can get answers and practice changes; the claim gets compensation.
Not automatically. Breach is measured against NICE NG12 and RCGP standards; causation depends on whether earlier referral would have changed the prognosis. Some cancers progress fast and earlier referral wouldn't have altered the outcome - in which case there's a breach but not a compensable injury. A specialist solicitor can tell you early which side of that line your case sits.
Same framework. The defendant is the OOH provider or NHS 111 service operator. Phone-triage recordings are preserved for a defined period and are central evidence.
Yes. Private GPs are subject to the same standards and are usually indemnified through the MDU, MPS or a commercial insurer. The legal test is identical.
Often yes. Repeated presentations with the same symptom are a classic trigger for escalation under RCGP and NICE guidance. If each consultation was essentially a repeat without additional investigation or referral, that supports the breach case.
Potentially, but the law requires a real, measurable injury. A near-miss without harm generally isn't compensable. Shorter-term harm (a hospital admission, a fortnight's illness) can be modestly compensated; serious harm (permanent organ damage, ICU stay) attracts the full range of general and special damages.
Typical range: 2-4 years. Claims with admitted breach can be shorter. Serious permanent-injury cases are longer because settlement is held until prognosis stabilises.
Nothing up front. Nothing if the claim fails (subject to the CFA and ATE terms). If the claim wins, the success fee (up to 25% of general damages and past losses) is deducted from your settlement. Full terms given in writing before you sign anything.

I had been turned away by two other firms. Casibus actually read my records, spotted the causation angle, and ran a clinical negligence claim that settled at five figures.
M. WalkerMedical negligence / Settled 2024

Straightforward, no jargon, no pressure. They told me exactly what to expect at every stage, and when the settlement came through it was higher than I expected.
