Insurance Claim Medical Certificate - Professional Evidence
Many health, accident and travel insurers ask for medical evidence signed by a doctor before they will assess a claim. What they will accept is set by your policy wording, so read it first. Our online service supplies that documentation without an NHS wait that could delay your claim by weeks.
Each certificate follows an individual clinical assessment by a licensed UK doctor. It is supporting evidence for your claim, not a guarantee that the claim will be paid.
✔ Issued by a registered UK GP following clinical assessment
✔ Used as supporting evidence for health, accident, travel, and disability insurance claims
✔ Most requests reviewed same day, from £87

Certificate security
Every MedicalCert certificate can be checked as genuine
Each certificate is issued with anti-tampering protection and its own verification reference. If your employer, university, airline or insurer wants to confirm the document came from a GMC-registered doctor, they can check it against MedicalCert records. Altered or copied documents do not pass that check.
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. Insurers must handle claims promptly and fairly under FCA rules (ICOBS 8.1.1R). Many insurers ask for medical evidence before deciding travel cancellation, income protection, critical illness, or private medical insurance claims, but the exact evidence required depends on the policy wording and claim type. A certificate is supporting evidence, not a guarantee that a claim will be paid.
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. Insurance reports and letters sit outside the NHS GP contract, so a practice is under no obligation to provide one, and many have reduced or stopped offering non-clinical letter services because of workload pressures. A private medical certificate provides an alternative route to obtaining clinically valid evidence for your claim, signed by a GMC-registered doctor.For a letter confirming an injury or accident (not for an insurance claim), see our injury confirmation letter.
Types of Insurance Claims That May Require a Medical Certificate
Not every insurance claim needs medical evidence. Where a policy does ask for it, the documentation usually has to confirm the diagnosis, the relevant dates, and the impact on the claimant's ability to travel or work. What counts as acceptable evidence is set by your policy wording, not by any general rule. The most common categories are:Travel Insurance - Holiday Cancellation
For travel or holiday cancellation insurance claims, we have a dedicated certificate designed specifically for this purpose. See our travel cancellation certificate for what that type of claim usually needs.
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. In its published guidance on travel insurance claims, the Financial Ombudsman Service says a customer usually needs to provide some medical evidence before it would uphold a complaint, and that where there is a good reason why no evidence is available from the treating doctor, it might accept medical evidence from a UK doctor instead.| 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 | Used by many travel and income protection insurers. Some forms ask specifically for the treating GP or specialist, which a remote service cannot satisfy |
| 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 | Decided by your insurer under the policy wording. Some policies require evidence from the doctor or specialist who treated you, which a remote service cannot provide |
| 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 obliged 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 states that doctors are not bound by their terms of service to provide these reports. Some policies also require the form to be completed by the GP or specialist who actually treated you, and no remote service can meet that condition. Always check your policy wording before submitting documentation.
The Challenge of Getting Insurance Medical Evidence from an NHS GP
NHS GPs are not obliged to complete insurance claim forms or write letters for non-clinical purposes. Some will do so as a private service, and many surgeries have reduced or stopped offering it because of workload pressures. The BMA publishes suggested fees for this work, for example £104 for a GP report for insurance applicants, but it states that these are for guidance only and that the figures were last agreed in 2006. Each practice sets its own rate. 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

How to Get an Insurance Medical Certificate Online
Check what your insurer requires

Get StartedFrequently Asked Questions
Will my insurer accept a private medical certificate from MedicalCert?
No insurer is obliged to accept it, and MedicalCert cannot promise that yours will. 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. Acceptance is decided by your insurer under its own policy wording, and some policies specifically require documentation from the GP or specialist who originally treated you, which a remote service cannot provide. 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 many insurers use their own medical evidence form. Read the form first: if it asks for the doctor who treated you, or for access to your full medical records, a remote service cannot complete it. Please ensure the form is clearly legible 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 because of workload pressures, or will only do so for their own registered patients. Each practice sets its own fee and its own turnaround, so ask yours before you rely on it. 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?
No. The FCA's Insurance: Conduct of Business Sourcebook requires an insurer to handle claims promptly and fairly and not to reject a claim unreasonably (ICOBS 8.1.1R), but it does not oblige an insurer to accept any particular form of medical evidence. Policy terms vary, so ask your insurer's claims team what it will accept before you buy anything. If you think a claim has been rejected unfairly, complain to the insurer first. For most complaints the firm has eight weeks to send a final response, after which you can refer the matter to the Financial Ombudsman Service, which handles complaints about financial businesses regulated by the FCA. You then have six months from the date of that final response to bring the complaint to the Ombudsman, and it will usually not be able to help after that unless there were exceptional circumstances (FCA Handbook DISP 2.8.2R).
