What are the Elements of a Medical Negligence Claim?

A medical negligence claim in the UK requires four elements:
(1) duty of care,
(2) breach of duty (measured by Bolam/Bolitho and Montgomery for consent),
(3) causation (the negligence caused the harm), and
(4) damage (loss and injury). Most adult claims have a three-year time limit, running from the date of injury or date of knowledge.

What are the elements of a medical negligence claim?

In UK law, the building blocks are straightforward—though proving them takes care and experience.

1) Duty of care

Healthcare professionals and organisations (NHS and private) owe a duty of care to their patients. That part is rarely in dispute.

2) Breach of duty (the legal tests)

Next, you must show the clinician fell below the acceptable standard.

• Clinical skill and decision-making — the Bolam test: a clinician is not negligent if they acted in accordance with a practice accepted as proper by a responsible body of medical opinion. However, the court may reject expert opinion if it isn’t logically defensible—the Bolitho refinement.
• Consent and information — Montgomery: since 2015, doctors must take reasonable care to ensure patients are aware of material risks and reasonable alternatives. What is “material” depends on the patient’s circumstances and what a reasonable person in that position would want to know.

Put simply: clinicians must meet a competent medical standard and properly inform you so you can make a real choice about treatment.

3) Causation (“did the breach cause the harm?”)

You must then prove—on the balance of probabilities—that the breach caused your injury (the “but for” test). Courts scrutinise this carefully, especially where there are complex medical histories. Bolitho also highlights how courts test expert reasoning on what would have happened if proper care had been given.

4) Damage (loss and harm)

Finally, you need actual loss: pain, suffering and loss of amenity (general damages), plus financial losses such as earnings, care, treatment, aids, and home adaptations (special damages). Together, these make up your settlement or award.

How recent court decisions affect claims (in brief)

• Informed consent is patient-centred: Montgomery v Lanarkshire Health Board reset the standard for what must be explained to patients.
• Secondary victim claims are now tightly limited: in Paul v Royal Wolverhampton NHS Trust [2024] UKSC 1, the Supreme Court narrowed when family members can recover for psychiatric injury witnessed during a medical crisis.

Limitation: when is the deadline to start a claim?

Timing matters. Most adult medical negligence claims must be issued in court within three years of either:

• the date of injury, or
• the date of knowledge (when you first reasonably knew your injury was significant, attributable to potential negligence, and who was responsible).

Important exceptions:

• For children, time runs from their 18th birthday (so usually until age 21).
• If a person lacks mental capacity, limitation is paused while the disability persists.

Tip: limitation can be complex. Courts also have a discretion to allow late claims in some circumstances, but you should seek advice promptly.

The pre-action protocol (how claims start and progress)

Before court, parties must follow the Pre-Action Protocol for the Resolution of Clinical Disputes. In practice, your representative sends a detailed Letter of Claim, and the Defendant usually has four months to investigate and give a Letter of Response. The protocol promotes early disclosure, investigation, and settlement where possible.

The UK context: why this matters

Clinical negligence costs remain a major public issue. Recent reports show billions paid annually across NHS schemes, with liabilities and maternity failings frequently in the news—underlining the importance of safety and accountability.

What evidence helps prove the elements?

To prove breach, causation, and damage, your case will typically rely on:

• Medical records (GP, hospital, community).
• Independent expert reports in the relevant specialties.
• Witness statements (you and your family).
• Financial evidence (earnings, care, travel, treatment costs).

Additionally, complaints made to the NHS (via PALS or the provider’s complaints process) can surface helpful information—though a complaint is not mandatory for a legal claim.

Compensation: how is it calculated?

Courts use two components:

1. General damages – for pain, suffering and loss of amenity. Judges look at the Judicial College Guidelines (JCG) to identify an indicative band for the injury’s severity. The current edition is the 17th (2024).
2. Special damages – your financial losses (past and future), such as care, case management, therapy, equipment, adapted housing, and loss of earnings.

Indicative general damages (JCG-style bands, rounded)

These figures are broad, illustrative ranges only. Every case is different and awards may be higher or lower after expert evidence. The “special damages” part can be very substantial in serious cases.

Injury type (examples)	Typical JCG band (rounded)
Very severe brain injury (24/7 care, profound disability)	£300,000–£430,000
Moderate brain injury (cognitive/behavioural impact)	£90,000–£220,000
Severe psychiatric injury	£70,000–£140,000
Less severe psychiatric injury	Up to ~£20,000
Loss of one eye	~£50,000–£70,000
Total blindness	£260,000–£350,000+

Note: in catastrophic injury claims (e.g., severe birth injury leading to cerebral palsy), special damages for lifelong care, therapy, accommodation, and equipment can push total settlements into seven or eight figures. Recent UK reporting highlights the scale of these liabilities.

Frequently Asked Questions

1. What if I only realised months (or years) later?
The three-year clock may run from your date of knowledge, not the treatment date. Please ask us to assess this carefully.

2. Do I have to complain to the NHS first?
No. However, using PALS or the provider’s formal complaints route can surface useful information. We’ll advise on timing so you don’t miss limitation.

3. What about claims by family members who witness events?
After Paul v Royal Wolverhampton [2024] UKSC 1, such secondary victim claims are tightly constrained in medical settings. We’ll discuss if this applies.
