Last updated 8th December 2025. Delayed diagnosis claims are the legal process in which patients can pursue compensation for being avoidably harmed as a result of their care falling below the minimum expected standard. The fallout of a diagnostic delay can be deeply distressing, as patients may face more invasive treatments, long-lasting health consequences, and worries about the future. While medical negligence compensation can’t erase what happened, it can provide financial relief during this very difficult time.
Key Takeaways
- A healthcare professional may delay a diagnosis by misinterpreting test results (e.g., X-rays and MRIs), failing to refer a patient when appropriate, or failing to review medical records as part of the examination process.
- Delays often affect the diagnosis of cancers, infections, fractures, and heart conditions.
- Diagnostic delays can lead to patients requiring more aggressive treatment, particularly in cases of cancer, neurological conditions, and strokes.
- In some cases, especially cancer and sepsis, a delay in diagnosing a condition can lead to reduced life expectancy or lower survival rates.
- Our medical negligence solicitors have extensive experience in providing tailored, empathetic guidance to clients pursuing compensation for a delayed diagnosis.

Can I Claim Compensation For A Delay In Diagnosis?
When you seek medical attention, the healthcare professionals treating you automatically owe you a duty of care. This means that they must provide care and treatment that meets an appropriate standard. Failure to do so would be considered a breach of duty.
If you have an injury or condition that worsened due to a delayed diagnosis, this might be considered medical negligence. However, in order to have good grounds to make a delayed diagnosis claim, you will need to demonstrate that you meet the medical negligence claims criteria. This means that you need evidence that proves:
- You were owed a duty of care.
- This was breached by not receiving the correct diagnosis in time.
- As a result of this breach, you experienced unnecessary pain and suffering, causing avoidable harm.
You can make a medical negligence claim against the NHS or a private medical institution.
The term ‘delayed diagnosis’ could refer to:
- Not being diagnosed with an illness following the delay of tests or test results (or some other delay).
- A misdiagnosis of another condition that leads to the delay of a correct diagnosis.
If any of the above situations apply to you, get in contact today. Not all delayed diagnosis cases are eligible to become claims. A member of our team will let you know if your case can be pursued.
Average Compensation For Delayed Diagnosis Claims
The term ‘average compensation’ suggests that there is a routine way to deal with delayed diagnosis claims. However, every medical negligence claim is handled on an individual basis. As such, the compensation awarded for each successful outcome will vary accordingly.
Medical negligence settlements may consist of general damages (awarded for your pain and suffering) and special damages (awarded for any financial losses caused by the delay in your diagnosis).
To help arrive at a figure for general damages, those responsible for calculating compensation may refer to the Judicial College Guidelines (JCG). This is a resource that sets out guideline compensation brackets for various types of harm. The list below provides some of these, with the exception of the first figure.
These figures are intended to be used as a guide only.
- Multiple Serious Injuries or Side Effects and Several Instances of Special Damages – There has been more than one side effect or condition following a delayed diagnosis as well as a loss of earnings – Up to £1,000,000+
- Paraplegia – Paralysis injuries in this bracket will be measured by factors including depression, age, life expectancy, and pain level – £267,340 to £346,890
- Bowel – (b) – Loss of bowel function, colostomy is likely needed – Up to £183,190
- Brain – Moderate (ii) -Intellect is affected negatively, massively reduced ability to work, risk of epilepsy – £110,720 to £183,190
- Bladder – (b) – Non-existent bladder control and function – Up to £171,680
- Eye – loss of sight in one eye and reduced function in the other – as stated, but with extra issues such as double vision – £78,040 to £129,330
- Post-Traumatic Stress Disorder – Severe – The patient will have difficulty working and functioning as they did before any trauma – £73,050 to £122,850
- Kidney – (b) – High risk of future issues like recurrent urinary tract infections and consideration for future high medical expenses – Up to £78,080
- Digestive System – Severe toxicosis leading to hospital admission, ongoing incontinence, irritable bowel syndrome, significant impact on life – £46,900 to £64,070
- Ear – Total loss of hearing in one ear – as stated – £38,210 to £55,570
Special Damages – What You Can Claim For
Special damages are designed to compensate you for any financial losses you have suffered following medical negligence. We’ve listed some of the things you might be able to claim delayed diagnosis compensation for.
- Medical expenses – for example, new mobility aids.
- Counselling.
- Loss of earnings.
- Prescriptions.
- Care in your home (and future care costs).
- Assistance with gardening, cooking, and cleaning.
- Travel costs like going to and from the hospital.
- Childcare.
The list above is not exhaustive, and you may be able to claim for other financial losses.
Examples Of Delayed Diagnoses
A healthcare provider causing unnecessary patient harm by misinterpreting test results, not investigating symptoms, or failing to make specialist referrals is among the more common examples of delayed diagnosis claims. Below, we look at some scenarios to provide context for how substandard care can result in diagnostic delays, cause avoidable patient suffering, and potentially give rise to a compensation claim.
- Testing: A patient undergoes an ultrasound to determine if the symptoms which showed up on a mammogram are indeed breast cancer. However, the doctor responsible for reviewing the results misinterprets the findings and recommends against performing a biopsy. This allows the disease to spread to other parts of the body, leaving the patient with post-traumatic stress disorder and requiring much more intensive treatment.
- Examination: During triage at A&E, an attending nurse ignores several symptoms of a patient with signs of a leg fracture and concludes they have a sprain. The patient is later seen by a doctor, whose inadequate physical examination leads to the fracture being completely missed. This failure means the bone doesn’t heal correctly and leads to the patient experiencing permanent stability issues.
- Referrals: Despite showing multiple signs of deep vein thrombosis (DVT), including swelling and unexplained pain in their leg, a patient is told by their GP that they likely have a muscle strain. The doctor doesn’t refer them for an ultrasound, which results in the blood clot travelling and causing long-term lung damage.
Our advisors are available 24/7, so please don’t hesitate to share your experience of a delayed diagnosis in complete confidence. They are here to listen and can help determine if you can claim compensation with one of the expert solicitors from Advice.
The Impact Of A Delayed Diagnosis
As mentioned, a delayed diagnosis can lead to many issues. One of the most prevalent is a disease or condition spreading further than it would have, requiring more treatment and having a greater effect on a patient’s quality of life.
Sometimes, a delay in diagnosis can have tragic results, such as a patient requiring medical adjustments for the rest of their life or even wrongful death. Because of these consequences, it’s important to speak out against medical negligence. Making a delayed diagnosis claim is a way you can do this.
Can I Claim On Behalf Of Someone Else?
You can make a delayed diagnosis claim on behalf of somebody else, but only in certain circumstances. If you choose to represent somebody, you would become what is known as a litigation friend. This position must be approved by the court and the claimant.
You can only act as a litigation friend in the following circumstances: you are claiming for someone who is under 18, or for someone who lacks the mental capacity to make a claim themselves. Our advisors can give you more information about litigation friends if your claim is eligible.

How To Start Your Delayed Diagnosis Claim
If you feel you may have suffered from medical negligence, don’t hesitate to reach out to our team. A member of our team will ask you questions about your potential claim to see if it can be pursued. If so, you will be connected to one of our specialist medical negligence solicitors.
Gathering Evidence To Prove Your Case
Gathering evidence for any case is important, but particularly for a medical negligence claim. The pieces of evidence below will be beneficial in proving a delay in diagnosis.
- Medical records. These will show the tests you had or didn’t have.
- A timeline of all the appointments you attended to show how things proceeded.
- Witness statements. These statements can be from family members, friends, or other medical professionals involved in your case. If you note their contact details, the statement can be given later on in the process.
In addition to the above evidence, your medical negligence solicitor is likely to schedule you for an independent medical report. This report will give an unbiased look into your medical history and could help to prove any medical negligence you suffered. Furthermore, it will help assess the full extent of the harm you suffered which will ensure that your claim is accurately valued.
Moreover, for special damages, you’ll need receipts, payslips, and other relevant evidence to prove the financial losses you are claiming for.
Time Limits For Starting A Claim
Under the Limitation Act 1980, those wishing to make a medical negligence claim have three years to do so. The three years begin on the date you became aware medical negligence occurred. There are some exceptions to this time limit, which our advisors can assist you with if your claim is valid.
How Long It Takes To Receive Compensation
Medical negligence claims can take a while to settle, particularly if your claim requires lots of evidence and the negligence is more difficult to prove. Nevertheless, you should receive compensation within a one-month time period once your solicitor has received the money.
How Our Solicitors Can Help You Claim
Our specialist medical negligence solicitors can assist you in gathering the correct evidence, which is crucial in a medical negligence case. They will additionally piece the timeline of your case together, along with this evidence, and provide support and updates during a stressful time. Our solicitors have decades of experience supporting delayed diagnosis claims.
What’s more, our solicitors operate on a No Win No Fee basis under a Conditional Fee Agreement. This means you:
- Don’t pay any solicitor’s fees upfront or as the claim progresses.
- Won’t be asked to make a payment for your solicitor’s costs if your claim is not successful.
- Will only have to pay a small success fee to your solicitor if your claim succeeds. This percentage is subject to a legislative limit, thus ensuring that you get to keep the majority of the compensation awarded to you.
Delayed Diagnosis Claims – Frequently Asked Questions
Read our frequently asked questions about diagnosis claims, including whether you can pursue compensation if you suffered unnecessary harm at a GP practice or have an underlying condition.
What is A Delayed Diagnosis?
A delayed diagnosis is a situation in which a medical professional doesn’t identify a condition within a reasonable timeframe, often due to misinterpreting test results or failing to act on recognisable symptoms. Delays can lead to unnecessary treatment, avoidable harm, and worsened outcomes.
What Conditions Commonly Involve Delayed Diagnosis Claims?
Cancers, infections (e.g. sepsis), heart attacks, strokes, and fractures are some of the conditions commonly involved in delayed diagnosis claims.
Can I Still Claim If I Had An Underlying Condition Anyway?
Yes, you can still claim if you had an underlying condition, as you can seek compensation for the additional pain, suffering, and financial loss you experienced due to the negligent care.
Will I Need A Medical Expert To Support My Claim?
In most cases, you will need a medical expert to support your claim for delayed diagnosis, and their independent report can provide valuable evidence of the extent and nature of the harm you suffered.
Can I Claim On Behalf Of A Loved One?
Yes, by becoming a litigation friend, you can make a delayed diagnosis claim on behalf of a loved one if they cannot pursue compensation for themselves because they are below 18 or mentally incapacitated.
What If The Delay Happened In A&E Or During A GP Appointment?
You can still claim compensation if the delay happened in A&E or during a GP appointment, so long as you have proof that you were avoidably harmed as a result of substandard care.
Do Delayed Diagnosis Claims Go To Court?
Delayed diagnosis claims can go to court if there are disputes over liability or disagreements concerning compensation, but most cases are settled before reaching this stage.
