What is a Never Event?
Short answer
A Never Event is a type of serious NHS patient safety incident that is considered wholly preventable, because national guidance or safety recommendations exist that provide strong systemic protective barriers — and those barriers should mean the incident essentially never happens if they are properly followed. NHS England maintains the current Never Events list (the 2018 list remains in force while a revised framework is developed).
Every Never Event is a form of clinical negligence, but the reverse isn't true — most negligence involves harm that doesn't fall into one of these specific, defined categories. What makes a confirmed Never Event distinctive in a legal claim is that breach of duty is rarely seriously contested: the entire point of the list is that these incidents should not happen when recognised safeguards are followed.
Examples of Never Events
Wrong-site surgery
Operating on the wrong limb, the wrong level of the spine, or the wrong organ — despite the WHO Surgical Safety Checklist and NHS surgical site marking protocols specifically designed to prevent it.
Retained foreign object post-procedure
A surgical swab, instrument, or guidewire left inside a patient after the operation or procedure has concluded — despite mandatory counting procedures that should catch this before the patient leaves theatre.
Wrong implant or prosthesis
Fitting a hip, knee, or other implant of the wrong size or type, or in the wrong orientation, contrary to the pre-operative plan.
Misplaced naso- or oro-gastric tubes
A feeding tube inserted into the lung rather than the stomach, and feed or fluid then administered through it, despite required checks (pH testing, X-ray confirmation) that exist specifically to catch this before feeding begins.
Wrong route administration of medication
Medication given by the wrong route — most seriously, a drug intended for oral or epidural administration given intravenously instead, which can be fatal depending on the drug involved.
Transfusion of the wrong blood type
Giving a patient blood or blood components that don't match their confirmed blood group, despite the multiple identity-check safeguards built into the transfusion process.
Several of these have their own dedicated guides on this site — see retained swab claims, catheter and guidewire retention, and feeding tube negligence.
How Never Events are reported and investigated
NHS trusts are required to report Never Events via the national Strategic Executive Information System (StEIS) and to carry out a local serious incident investigation. Under the statutory Duty of Candour, the trust must also tell the patient (or their family) that a notifiable safety incident occurred, explain what is known about what happened, and provide a written apology — separately from, and regardless of, any legal claim. See our guide to the duty of candour for what the regulation requires.
Does a Never Event guarantee compensation?
Not automatically — you still need to show the Never Event caused you harm, and the value of a claim depends entirely on the extent of that harm, not on the incident being classed as a Never Event in itself. But because the whole category exists to describe incidents that shouldn't happen given the safety barriers in place, disputes in these cases tend to focus on causation and value rather than on whether a breach of duty occurred at all.
What evidence does a Never Event claim need?
- The trust's Duty of Candour notification and any written apology.
- The serious incident investigation report, where available.
- Operative, procedural or medication administration records covering the incident itself.
- Records of the harm caused and any further treatment needed.
- Independent expert evidence, where the extent of harm — rather than breach of duty — is in dispute.
What is the time limit?
Three years from the date of the incident, or from the date of knowledge — under the Limitation Act 1980, the same as any other clinical negligence claim.
How is a Never Event claim funded?
As with other clinical negligence claims, these are almost always funded on a Conditional Fee Agreement — no win no fee. You pay nothing upfront, and nothing if the claim doesn't succeed.

Frequently asked questions
Does a Never Event automatically mean I can claim compensation?
No, but it makes a claim significantly more straightforward. A Never Event is, by definition, something that should not happen when recognised safety measures are followed — so the fact it happened is strong evidence that something went wrong. You still need to show that it caused you harm, but breach of duty is rarely seriously disputed once a genuine Never Event is confirmed.
Will the hospital tell me if a Never Event happened?
It should. NHS trusts have a statutory Duty of Candour requiring them to tell patients when a notifiable safety incident occurs, explain what happened, and apologise. Never Events must also be reported by the trust via the Strategic Executive Information System (StEIS) and are subject to a local investigation.
What's the difference between a Never Event and ordinary clinical negligence?
Every Never Event is a form of clinical negligence, but not every act of negligence is a Never Event. Never Events are a specific, defined list of serious incidents — wrong-site surgery, retained instruments, wrong-route medication and others — where national safety barriers exist specifically to prevent them. Most negligence claims involve harm that doesn't fall into one of these defined categories.
Can I get a copy of the trust's Never Event investigation report?
You can request it, and your solicitor can request it formally as part of gathering evidence. Trusts are expected to share the findings of a serious incident investigation with the patient or family under the Duty of Candour, though the level of detail shared varies.
How long do I have to bring a claim after a Never Event?
The same three-year limitation period as any other clinical negligence claim, running from the date of the incident or from your date of knowledge — under the Limitation Act 1980.
