Medical Negligence — No Win No Fee

England & WalesLast reviewed 18 September 2026

Medical negligence occurs when a healthcare professional's treatment falls below the standard reasonably expected, causing injury to the patient. Many UK solicitors handle these cases on a no win no fee (CFA) basis, though they are complex and require expert medical evidence.

What Is Medical Negligence?

Direct Answer: Medical negligence occurs when a healthcare professional's treatment falls below the accepted standard of care (the Bolam test), causing injury. Claims against NHS and private providers can be brought on a no win no fee CFA. The limitation period is 3 years from the date of injury or date of knowledge.

Medical negligence (also referred to as clinical negligence) arises when a healthcare professional — whether a GP, surgeon, consultant, nurse, dentist, or other clinician — provides treatment that falls below the standard of care reasonably expected, and that substandard treatment causes injury or harm to the patient. The claim may be against the individual practitioner, an NHS Trust, or a private healthcare provider.

What Is the Legal Standard — Bolam and Bolitho?

The standard of care in English law is set by the Bolam test (Bolam v Friern Hospital Management Committee [1957]): a doctor is not negligent if they acted in accordance with a practice accepted as proper by a responsible body of medical professionals skilled in that particular art.

This was refined by Bolitho (Bolitho v City and Hackney Health Authority [1998]): the court may assess whether the body of opinion relied upon has a logical basis and has properly weighed risks against benefits. This prevents a purely deferential approach to medical opinion.

What Are the Common Types of Medical Negligence?

  • Surgical errors — wrong-site surgery, nerve damage, retained instruments
  • Misdiagnosis or delayed diagnosis — failure to diagnose cancer, stroke, or other serious conditions
  • Birth injuries — cerebral palsy, Erb's palsy, hypoxic brain injury due to birth mismanagement
  • Medication errors — wrong drug, wrong dose, contraindicated combinations
  • Failure to obtain informed consent — proceeding without properly explaining risks (Montgomery v Lanarkshire)
  • A&E negligence — errors in emergency treatment or triage

What Is NHS Resolution?

Claims against NHS bodies in England are managed by NHS Resolution (formerly the NHS Litigation Authority). NHS Resolution handles the defence of claims, manages the Clinical Negligence Scheme for Trusts (CNST), and publishes annual reports on claims data. In 2022/23, NHS Resolution received over 13,000 new clinical negligence claims.

No Win No Fee for Medical Negligence

Medical negligence claims can be pursued under a Conditional Fee Agreement. However, because these cases require substantial upfront investment in expert evidence (often multiple expert reports from different specialities), solicitors are selective. Disbursements for medical negligence cases can run into thousands of pounds, making ATE insurance particularly important.

Frequently Asked Questions

What is medical negligence in the UK?

Medical negligence (also called clinical negligence) occurs when a healthcare professional provides treatment that falls below the standard reasonably expected, causing injury or harm to the patient. This applies to NHS and private treatment.

Can I bring a medical negligence claim on a no win no fee basis?

Yes. Many solicitors offer Conditional Fee Agreements for medical negligence claims. However, because these cases are complex and expensive (requiring expert medical evidence), solicitors are selective about which cases they accept.

How long do I have to make a medical negligence claim?

The limitation period is generally 3 years from the date of the negligent treatment or the date of knowledge — when you first became aware (or should have become aware) that the treatment may have been negligent. Different rules apply for children and those lacking capacity.

What is the Bolam test?

The Bolam test is the legal standard for medical negligence in England and Wales. It states that a doctor is not negligent if they acted in accordance with a practice accepted as proper by a responsible body of medical opinion. This was refined by Bolitho, which allows courts to assess whether the opinion has a logical basis.

How much compensation could I receive?

This depends on the severity of the injury, the impact on your life, and your financial losses. Medical negligence awards range from a few thousand pounds for minor injuries to millions for catastrophic injuries such as cerebral palsy or spinal cord damage.
