A medical certificate for an insurance claim is a doctor-signed document that confirms an illness, injury, or medical condition as formal evidence for an insurer. UK insurance companies require this documentation under FCA claims handling rules (ICOBS 8) before settling travel cancellation claims, income protection claims, critical illness claims, and private medical insurance appeals.
Obtaining the right medical evidence is often the most difficult part of an insurance claim. Under the Financial Conduct Authority's Insurance: Conduct of Business Sourcebook (ICOBS 8), insurers must handle claims fairly and promptly, but they require appropriate documentation before doing so. NHS England's 2024/25 GP Patient Survey found that only 34.4% of patients were able to see or speak to their preferred GP, and many practices have reduced or stopped offering non-clinical letter services due to workload pressures. A private medical certificate provides an alternative route to obtaining clinically valid evidence for your claim, signed by a GMC-registered doctor.Types of Insurance Claims That May Require a Medical Certificate
The Association of British Insurers (ABI) reports that UK insurers pay out over £22 billion in general insurance claims annually. For claim types that require medical evidence, the documentation must typically confirm the diagnosis, relevant dates, and impact on the claimant's ability to travel or work. The most common categories are:Travel Insurance - Holiday Cancellation
- Illness or injury preventing travel
- Diagnosis of a new condition close to departure
- Unfit to travel certificate for cancelled flights or holidays
- Medical evidence of a condition that worsened unexpectedly
Income Protection & Sick Pay
- Long-term illness preventing return to work
- Evidence for employer statutory sick pay disputes
- Private income protection policy medical evidence
- Critical illness claim supporting documentation
Life, PMI & Other Policies
- Private medical insurance (PMI) referral support letters
- Life insurance claim medical evidence
- Personal accident insurance injury confirmation letter
- Mortgage protection insurance medical evidence
What Insurers Typically Require as Medical Evidence
Different insurers and different claim types require different forms of documentation. Understanding what your insurer is asking for before applying will help ensure your documentation is accepted first time. The Financial Ombudsman Service notes that inadequate or incorrect medical documentation is among the most common reasons for insurance claim disputes in the UK.| Document Type | What It Is | Accepted For |
|---|---|---|
| Medical certificate / doctor's letter | Signed letter from a GMC-registered GP confirming diagnosis, dates, and impact on fitness to travel or work | Travel insurance cancellation, income protection, PMI supporting evidence |
| NHS Med3 Fit Note | Official NHS fitness for work certificate issued under the Social Security (Medical Evidence) Regulations 1976, confirming inability to work | Employment sick pay - not always accepted for insurance claims; check with your insurer |
| Insurer's own claim form | Form provided by the insurer for a GP to complete, with specific questions about diagnosis, prognosis, and treatment | Required by many travel and income protection insurers; can be uploaded to MedicalCert for completion |
| Medical report from abroad | Report from treating doctor during travel confirming illness or injury and treatment received overseas | Travel insurance overseas medical claims |
NHS Fit Note vs Private Medical Certificate for Insurance Claims
| Feature | NHS Med3 Fit Note | Private Medical Certificate |
|---|---|---|
| Primary purpose | Confirms fitness for work under employment law | Provides medical evidence for insurance, travel cancellation, and other non-NHS purposes |
| Content covered | Work capability only; does not address fitness to travel, onset dates, or prognosis | Diagnosis, dates, fitness to travel/work, and prognosis as required by insurer |
| Insurer acceptance | Not always accepted for insurance claims; many insurers require additional documentation | Accepted by most UK insurers when signed by a GMC-registered doctor |
| Typical turnaround | Issued at appointment but non-urgent documentation requests may take 2-4 weeks | Same day or by 9AM the following morning with express service |
| Can include insurer's form | NHS GPs are not obligated to complete insurer forms | Yes; insurer-specific forms can be uploaded for the doctor to complete |
An NHS Med3 fit note confirms you are unfit for work, but it may not contain the specific information your insurer needs, such as confirmation that you were unfit to travel, the onset date of your condition, or a clinical opinion on your prognosis. Many insurers require a separate doctor's letter or their own claim form to be completed. The British Medical Association (BMA) confirms that GPs are not contractually required to provide insurance reports or complete insurer documentation under their NHS contract. Always check your policy wording before submitting documentation.
The Challenge of Getting Insurance Medical Evidence from an NHS GP
NHS GPs are not obligated to complete insurance claim forms or write letters for non-clinical purposes. While some will do so as a private service, for which they may charge between £25 and £120 depending on the practice, many GP surgeries have reduced or stopped offering this service due to workload pressures. The BMA's recommended private fee for non-NHS medical reports starts at approximately £100, and individual practices set their own rates. Common obstacles include:- Long waits for non-urgent documentation requests, often 2-4 weeks or longer
- GP practices declining to write letters retrospectively for insurance purposes
- Insurers' specific form requirements that NHS GPs decline to complete
- The patient being registered with a different GP at the time they fell ill
- GP practices prioritising clinical care over administrative documentation under NHS England guidance

Get StartedFrequently Asked Questions
Will my insurer accept a private medical certificate from MedicalCert?
Most UK insurers accept medical documentation signed by a GMC-registered doctor, regardless of whether the doctor is NHS or private. MedicalCert certificates are signed by GMC-registered doctors and include the doctor's GMC registration number, a confirmed diagnosis with relevant dates, and a unique verification reference. However, final acceptance is at the discretion of your insurer, and some policies specifically require documentation from the GP or specialist who originally treated you. Always check your policy wording and, if in doubt, contact your insurer before applying to confirm what medical evidence they require.
Can I get a retrospective medical certificate for an insurance claim?
In many cases, yes, subject to clinical review. A retrospective medical certificate is backdated documentation confirming that you were unwell on a specific past date, issued after the fact based on supporting evidence. MedicalCert's doctors can issue retrospective certificates where you can provide sufficient evidence of when you became unwell, such as prescription records, hospital discharge letters, pharmacy dispensing records, or GP appointment records. The reviewing doctor will assess whether a retrospective certificate is clinically justified. If the evidence is insufficient, documentation will not be issued.
My insurer wants their own form completed by a GP. Can MedicalCert do this?
Yes. If your insurer provides a specific medical form for a doctor to complete, you can upload it during the MedicalCert consultation process. The reviewing GMC-registered doctor will complete the form where the clinical information supports doing so. This is common for travel insurance cancellation claims, where insurers such as Aviva, AXA, and Allianz often require their own medical evidence forms. Please ensure the form is clearly legible and complete before uploading.
Why won't my NHS GP complete my insurer's form?
NHS GPs are not contractually required to complete insurance forms or write letters for non-NHS purposes under their NHS contract. The British Medical Association (BMA) classifies insurance reports as private (non-NHS) work. Many practices have reduced or stopped offering this service due to significant workload pressures, or will only do so for registered patients with waiting times of 2-4 weeks and a private fee typically ranging from £25 to £120. A private medical certificate service like MedicalCert provides an alternative where a GMC-registered doctor can review your case and provide the required documentation based on the information and evidence you supply.
What evidence do I need to provide to get an insurance medical certificate?
The more evidence you can provide, the stronger the clinical basis for the certificate. Useful evidence includes prescription records or pharmacy dispensing receipts, hospital discharge letters or A&E attendance records, results letters from specialists or diagnostic tests, photographs or a video description of visible symptoms, and any existing documentation from previous healthcare contacts. The reviewing doctor will assess the evidence and issue a certificate only where there is a clear clinical basis for doing so, in accordance with GMC guidance on issuing medical reports.
Is a MedicalCert certificate the same as an NHS sick note?
No. An NHS Med3 fit note (commonly called a sick note) is a specific statutory document issued under the Social Security (Medical Evidence) Regulations 1976 for employment and statutory sick pay purposes. A MedicalCert certificate is a private medical letter signed by a GMC-registered doctor for non-NHS purposes such as insurance claims, travel cancellation evidence, and insurer form completion. The two serve different legal and administrative functions. Many insurers require a private doctor's letter rather than, or in addition to, an NHS fit note. Always check your specific insurer's requirements.
How long does it take to get a medical certificate for an insurance claim?
Through MedicalCert, most certificates are delivered same day after the GMC-registered doctor completes their clinical review. An express service is available with delivery by 9AM the following morning. By comparison, requesting insurance documentation through an NHS GP can take 2-4 weeks or longer for non-urgent requests, and some GP practices may decline the request entirely. MedicalCert consultations are available 24/7 online with no appointment required.
Does the FCA require insurers to accept private medical certificates?
The FCA's Insurance: Conduct of Business Sourcebook (ICOBS 8) requires insurers to handle claims fairly and promptly, but does not mandate that insurers accept any specific form of medical evidence. Most insurers accept documentation signed by any GMC-registered doctor, but individual policy terms vary. Your insurer's claims team can confirm what documentation is acceptable for your specific policy. If you believe your claim has been unfairly rejected due to the source of your medical evidence, you may be able to refer the matter to the Financial Ombudsman Service.
