What counts as A&E negligence and when you might have a claim
A&E (Accident & Emergency) negligence happens when a hospital's emergency department fails to meet the standard of care a reasonable doctor would provide, and that failure causes you harm. This is different from straightforward having a bad outcome or a long wait. The hospital must have done something wrong — misdiagnosed your condition, missed a symptom, delayed treatment when time mattered, or failed to refer you to a specialist — and that mistake must have directly caused injury, worsening of your condition, or additional treatment you would not otherwise have needed.
The core question is whether the A&E staff acted negligently, not whether you are unhappy with the result. A patient who waits six hours and then receives correct treatment has no claim, even if the wait was frustrating. A patient who waits six hours, is sent home with the wrong diagnosis, and suffers a heart attack the next day may have one, because the delay and misdiagnosis caused measurable harm.
Key Takeaways
- A&E negligence requires proof that the hospital fell below the standard of care a competent doctor would provide, and that this failure directly caused you physical or psychological harm.
- Common examples include misdiagnosis of serious conditions, failure to order necessary tests, sending a patient home without proper assessment, and delays in treatment that worsened the condition.
- You will need medical evidence from an independent doctor stating what the A&E staff should have done differently and how their actions caused your injury.
- The time limit to bring a claim is usually three years from the date of the negligent treatment or from when you first realised the harm was caused by negligence.
- Most A&E negligence claims are settled before trial, but the process typically takes 18 months to three years from start to resolution.
The legal standard: what "negligence" actually means in an A&E setting
Negligence in medicine is not judged by whether the outcome was perfect. It is judged by whether the doctor's actions fell below what other competent doctors in the same specialty would have done in similar circumstances. This is called the Bolam test, named after a court case that established the rule. A doctor is not negligent straightforward because they made a choice that turned out wrong; they are negligent if they acted in a way no reasonable doctor would have acted.
In A&E, this means the staff must assess you properly when you arrive, take your symptoms seriously, order appropriate tests or imaging if your presentation suggests you need them, and refer you to a specialist or admit you if your condition warrants it. If an A&E doctor sees a patient with chest pain and does not perform an ECG or blood tests, and that patient has a heart attack hours later, that is likely negligence. If an A&E doctor performs those tests, gets normal results, and the patient has a heart attack anyway, that is not negligence — the doctor acted as a reasonable doctor would have.
The second part of negligence is causation: the negligent act must have caused your harm. If you were going to suffer the same injury regardless of what the A&E staff did, you have no claim even if they were negligent. If the negligence directly led to your injury or made it worse, causation is established.
Common types of A&E negligence claims
Misdiagnosis or delayed diagnosis is the most frequent claim. This includes sending a patient home with the wrong diagnosis (such as telling someone with appendicitis they have indigestion), or failing to diagnose a serious condition at all. The harm occurs when the patient's condition worsens because treatment was delayed or never started.
Failure to perform necessary tests happens when a patient's symptoms clearly call for imaging, blood work, or other investigations, but the A&E staff do not order them. A patient presenting with sudden severe headache and neck stiffness should have a lumbar puncture or CT scan to rule out meningitis; if the A&E doctor does not order these and the patient has meningitis, that is negligence.
Inadequate assessment or history-taking occurs when staff do not ask the right questions or do not listen to what the patient tells them. If a patient reports they have chest pain and a family history of heart disease, but the A&E doctor does not take that history seriously and sends them home without investigation, that can be negligent.
Failure to refer or admit happens when a patient's condition clearly requires admission or specialist review, but the A&E staff discharge them instead. A patient with signs of a stroke should be admitted; if they are sent home and suffer a major stroke hours later, the failure to admit may be negligent.
Delays in treatment can be negligent when time is critical. If a patient with a ruptured appendix waits eight hours in A&E before being taken to theatre, and that delay causes sepsis or other complications, the delay may constitute negligence — though this depends on whether the delay was unavoidable or whether the staff recognised the urgency.
What you need to prove a negligence claim
You must establish four things: that the A&E staff owed you a duty of care (they did — you were their patient), that they breached that duty (they fell below the standard of a competent doctor), that you suffered harm (injury, worsening condition, additional treatment), and that the breach caused the harm. The most difficult part is usually proving breach and causation, because both require medical evidence.
You will need a report from an independent doctor in the same specialty as the A&E staff member who treated you. This doctor must state, in writing, what the A&E staff should have done, why their actual conduct fell below the standard of a reasonable doctor, and how that conduct caused your harm. Without this informed report, your claim cannot proceed. The NHS or the hospital's insurers will also obtain their own informed report, and if both experts agree the A&E staff were negligent, settlement is likely. If they disagree, the case may go to trial.
You will also need medical records showing your presentation, what tests or investigations were done (or not done), what the A&E staff documented, and your subsequent treatment and outcome. These records form the foundation of the informed's opinion.
Time limits and how long claims take
The time limit to bring a negligence claim is usually three years from the date of the negligent treatment. If you did not realise the harm was caused by negligence until later, the three-year clock may start from the date you first realised it — but this is complex and depends on the circumstances. If you were a child when the negligence occurred, the three-year limit does not start until you turn 18. If you lack mental capacity, the limit may not explore at all.
Do not wait until the last moment to seek information. Once you are past three years, you cannot bring a claim except in rare circumstances. If you think you may have a claim, contact a solicitor who handles medical negligence within the first year of the incident, even if you are still gathering information.
The process from initial instruction to settlement or trial typically takes 18 months to three years. The first stage is obtaining your medical records and instructing an informed. The informed's report takes 8 to 12 weeks. Once you have the report, your solicitor sends a letter of claim to the hospital. The hospital has four months to respond. If they admit liability, the case moves to negotiating damages. If they deny liability, the case proceeds toward trial, which can add another 12 to 18 months.
What damages cover and what you might recover
Special damages are financial losses you can prove: medical treatment you had to pay for, travel to appointments, lost wages, care costs, or equipment you needed because of the negligence. These are straightforward to calculate because you have receipts or payslips.
General damages cover pain, suffering, loss of amenity (loss of enjoyment of life), and psychological harm. The amount varies depending on the severity and duration of your injury. A patient who suffered a temporary worsening of their condition might recover £2,000 to £5,000 in general damages. A patient left with permanent disability or chronic pain might recover £20,000 to £100,000 or more. These figures vary widely and depend on the specific facts.
If the negligence caused you to need ongoing care, you may recover the cost of that care for life. If it caused you to lose earning capacity, you may recover the difference between what you would have earned and what you can now earn. These are called future loss damages and require informed evidence about your prognosis and earning potential.
When you should and should not pursue a claim
You should consider a claim if: an independent informed confirms the A&E staff fell below the standard of care, that breach directly caused you measurable harm, and you have suffered loss (financial, physical, or psychological) as a result. You should also have realistic expectations about the time and cost involved and be prepared for the possibility that the hospital will defend the claim.
You should not pursue a claim if: the informed's opinion is that the A&E staff acted reasonably given the information they had, even if the outcome was bad; if your harm is minor and the cost of pursuing the claim would exceed any recovery; or if you are not prepared for the stress of a claim that may take years to resolve. Some people find the process of reliving the incident and giving evidence distressing, and that is a legitimate reason to decline to pursue a claim even if you have a strong case.
A solicitor can advise you on the strength of your case, the likely level of damages, and the costs and timescale involved. Most medical negligence solicitors offer a free initial consultation and work on a conditional fee agreement (also called a no-win-no-fee arrangement), meaning you pay nothing unless the claim succeeds. You should understand what happens if the claim fails — you may be liable for the hospital's legal costs — and whether the solicitor's insurance covers that risk.
Frequently Asked Questions
Do I have a claim if I waited a long time in A&E but eventually got the right treatment?
A long wait alone is not negligence unless the delay caused harm. If you were eventually diagnosed and treated correctly, and the delay did not worsen your condition or cause additional injury, you have no claim. If the delay meant your condition deteriorated and you needed more intensive treatment than you would have needed if seen sooner, that may be negligence.
What if the A&E doctor made a mistake but I recovered fully?
If you recovered fully with no lasting harm, you have suffered no loss and cannot recover damages. Negligence requires both a breach of duty and harm caused by that breach. A mistake that causes no harm is not actionable. However, if you incurred costs (such as private treatment to correct the mistake), you may recover those costs.
Can I claim if I was not admitted to hospital but treated in A&E and sent home?
Yes. A&E negligence claims do not require admission. Many claims arise from patients who were assessed and discharged from A&E, only to suffer serious harm because the A&E staff missed or misdiagnosed their condition. The question is whether the staff fell below the standard of care, not whether you were admitted.
How much does it cost to bring a negligence claim?
If you instruct a solicitor on a conditional fee agreement, you pay nothing upfront and nothing if the claim fails — the solicitor's costs are paid from your damages if you win. You may be asked to pay for the informed's report upfront (typically £500 to £2,000), though some solicitors advance this cost. If the claim fails, you may be liable for the hospital's legal costs, which is why insurance is important.
What if I missed the three-year important date?
In rare circumstances, the court can allow a claim to proceed after three years if it is fair to do so, but this is difficult to establish. Do not assume you can claim after three years. If you think you may have a claim, seek information when ready, even if the incident happened more than three years ago — a solicitor can advise whether your case falls within an exception.
