Suing the NHS for medical negligence: A practical guide

If you or a loved one has suffered harm due to substandard NHS care, you may be entitled to compensation. Suing the NHS is possible where avoidable injury, suffering, or illness has occurred because an NHS Trust, hospital, or GP breached their duty of care.

Here’s what we cover in this guide:

• What NHS medical negligence is and when you may be able to make an NHS negligence claim
• Key time limits (including exceptions for children and lack of capacity)
• Common types of NHS negligence claims, including misdiagnosis, birth injury, and surgical errors
• How the NHS complaints process works and what rights you have
• The main steps in suing the NHS, including evidence, expert reports, and response times
• What you need to prove (breach of duty and causation)
• What NHS compensation can cover, including pain and suffering and financial losses
• Why people claim against the NHS and how Fletchers can help

Your legal rights as an NHS patient

If you believe NHS negligence has occurred, you have the right to:

• Access your full NHS medical records
• Make a formal complaint to the NHS Trust or GP practice
• Receive a written explanation and investigation outcome
• Seek independent legal advice about an NHS negligence claim

At Fletchers Solicitors, we support patients through both the complaints process and claims against the NHS, helping you understand which route is appropriate.

What is NHS medical negligence?

NHS medical negligence happens when treatment provided by NHS staff falls below the standard expected of a reasonably competent healthcare professional, and that failure causes avoidable harm.

To succeed in an NHS negligence claim, two key elements must be proven:

• Breach of duty: The care provided did not meet acceptable medical standards
• Causation: The breach directly caused harm or worsened your condition.

If you’re unsure whether your experience qualifies as NHS negligence, a specialist solicitor can review your case and explain whether you may be able to sue the NHS for negligence.

What is the NHS duty of candour?

The duty of candour means that NHS organisations are legally required to be open and honest with patients when something goes wrong. They must:

• Tell you about mistakes.
• Provide an explanation and apology.
• Investigate incidents thoroughly and share their findings.

This duty often forms part of NHS complaint investigations and can be an important early step before making an NHS negligence claim.

Types of NHS medical negligence claims

Patients may be able to bring a claim against the NHS for a wide range of medical errors. We support patients with medical negligence claims, including:

• Misdiagnosis: A condition is missed or wrongly diagnosed, leading to delayed or incorrect treatment.
• Birth injuries: Avoidable harm suffered by mother or baby during pregnancy or delivery.
• Cancer negligence: Failure to diagnose or treat cancer promptly.
• Amputation negligence: Medical mistakes that result in avoidable amputations.
• Medication errors: Prescribing the wrong medication or incorrect dosages.

Making an NHS complaint

Before pursuing a compensation claim, many patients start with a formal NHS complaint. While a complaint does not automatically lead to compensation, it can help clarify what went wrong and generate useful evidence.

You have the right to:

• Complain verbally or in writing
• Receive a written investigation and response.
• Have your concerns addressed, including details of any mistakes and their impact on your health.

We recommend reviewing resources from independent charities such as Action Against Medical Accidents (AvMA) for detailed complaint guidance.

How to sue the NHS

Suing the NHS can feel daunting, especially when you’re already dealing with the physical and emotional impact of medical negligence. Understanding the process can help you feel more confident about your options and what to expect.

An NHS negligence claim follows a formal legal process designed to investigate what went wrong, whether the care fell below acceptable standards, and whether that failure caused avoidable harm. 

Seek specialist legal advice

The first step in suing the NHS for negligence is speaking with a solicitor who specialises in NHS medical negligence claims. They will listen to what happened, review key details, and advise whether you may have a valid claim. 

At this stage, you don’t need to have all the answers or evidence. The purpose here is to understand your rights and whether further investigation is justified.

Gather medical records and evidence

If your solicitor believes there may be grounds for a claim, they will begin by obtaining your NHS medical records. These records are crucial in assessing:

• What treatment or diagnosis was provided
• Whether there were delays, errors, or omissions
• How your condition progressed as a result

Witness statements may also be obtained, and independent medical experts are often instructed to review your care and provide opinions on whether NHS negligence occurred.

Letter of Claim

Once sufficient evidence has been gathered, your solicitor will send a formal Letter of Claim to the NHS Trust responsible for your care. This letter sets out:

• The allegations of negligence
• How the NHS breached its duty of care
• The harm caused as a result
• The basis of the compensation claim

This marks the start of the legal process when suing the NHS.

NHS investigation and response

The NHS Trust has four months to investigate the claim and provide a written response. They may admit liability in full or in part, deny liability, or request further clarification.

During this period, your solicitor continues to build evidence and advise you on the strength of your claim.

Valuing the claim and funding

If liability is admitted (or becomes likely), your solicitor will assess the value of your NHS negligence claim. This includes:

• Pain, suffering, and loss of quality of life
• Past and future financial losses
• Ongoing care, treatment, or support needs

1. Most people sue the NHS on a No Win, No Fee basis, meaning there is no upfront cost and no legal fees to pay if the claim is unsuccessful. Legal aid and insurance options may also be available to you, which will be discussed with your solicitor.

Negotiation and settlement

Many medical negligence NHS claims are resolved through negotiation without the need for a court hearing. If the NHS makes an offer, your solicitor will advise whether it fairly reflects the impact of the negligence. 

If an agreement cannot be reached, court proceedings may be issued to protect your position. However, even then, many claims still settle before trial.

Court proceedings (if required)

In a small number of cases, a judge will decide whether negligence occurred and what compensation should be awarded. If this happens, your solicitor will guide and support you throughout, explaining each stage clearly and handling the legal complexity on your behalf.

Proving NHS negligence

To prove NHS negligence, your solicitor must show that:

1. Your care fell below the accepted medical standards.
2. This failure directly caused your injury or worsened your condition.

Strong evidence is essential, particularly independent expert medical opinions. Evidence gathered may include:

• Medical records: A full treatment history highlighting errors.
• Witness statements: From family, friends, or staff present.
• Independent medical experts: Unbiased opinions linking your harm to negligence.

How long does it take to sue the NHS?

The timeframe for suing the NHS depends on the complexity of your case. Typical stages of a claim include:

• Initial enquiry and case evaluation.
• Requesting medical records and expert assessments.
• Negotiation or, if needed, court proceedings.

While some cases settle quickly, complex cases can take much longer. Our specialist NHS solicitors aim to settle claims as quickly as possible so you can focus on recovery.

Time limits for NHS negligence claims

Time limits are an important part of NHS negligence claims, but they are often more flexible than people realise. Many patients delay taking action because they are focused on treatment, recovery, or simply trying to understand what went wrong. The law recognises this and, in certain circumstances, allows extended time to bring a claim.

In most cases, the standard time limit is three years, but when that period starts can vary depending on the situation.

• Standard rule: You must start your claim within three years of the incident or when you became aware of the harm.
• Children: The time limit begins on their 18th birthday.
• Mental incapacity: No time limit applies until capacity is regained.

Even when exceptions apply, it’s always best to seek advice as soon as possible. Medical records, witness recollections, and expert evidence are easier to obtain while events are still relatively recent. Delays can make investigations more difficult and may affect the strength of your claim.

NHS compensation: What can you claim?

Compensation in an NHS negligence claim may include:

• General damages: Pain, suffering, and loss of amenity.
• Special damages: Financial losses, such as care costs, medical expenses, and lost earnings.

Amounts vary based on the severity of injury, the impact on your daily life, and financial loss. Settlements can also range from thousands to multi-million-pound awards for severe cases.

Is it wrong to sue the NHS?

Suing the NHS isn’t about punishment or blame. NHS claims help improve patient safety, provide accountability, and ensure injured patients are not left to cope alone.
