A medical certificate for an insurance claim is a doctor-signed document confirming an illness, injury, or medical condition as evidence for your insurer. It is most commonly required for travel insurance cancellation claims, income protection claims, critical illness claims, and private medical insurance appeals. This guide explains what insurers typically require, when an NHS fit note is not sufficient, and how to obtain a private medical certificate quickly, subject to clinical review.
Insurance companies are obligated under FCA rules to process claims fairly and promptly, but they require appropriate medical evidence before doing so. For many claimants, the difficulty is not the insurance claim itself — it is obtaining the right medical documentation from a GP who may be under significant NHS time pressure. A private medical certificate provides an alternative route to obtaining clinically valid evidence for your claim.
Types of Insurance Claims That May Require a Medical Certificate
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.
| 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 — confirms 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 — often asks 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 — confirms illness or injury and treatment received overseas | Travel insurance overseas medical claims |
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. 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 £30–£100 or more — many GP practices have reduced or stopped offering this service due to workload pressures. Common obstacles include:
- Long waits for non-urgent documentation requests (often 2–4 weeks)
- GP practices refusing to write letters retrospectively for insurance purposes
- Insurers’ specific form requirements that NHS GPs decline to complete
- The person being registered with a different GP at the time they fell ill
A private medical certificate from MedicalCert provides a clinically reviewed, GMC-registered doctor-signed document that meets the standard expected by most UK insurers. Where your insurer has a specific form, this can be uploaded as part of the consultation process for the reviewing doctor to complete, where clinically appropriate.
What a MedicalCert Insurance Medical Certificate Includes
A medical certificate for insurance purposes issued by MedicalCert will typically include:
Doctor’s Letter / Certificate
- Your full name and date of birth
- Confirmation of the illness, injury, or condition
- Relevant dates — onset, duration, and current status
- Clinical opinion on fitness to travel or work (where applicable)
- Signed by a GMC-registered doctor with their registration number
- Unique verification reference for insurer checks
Your Insurer’s Own Claim Form
- Completion of your insurer’s specific form (upload at consultation stage)
- Doctor’s responses to insurer-specific questions about diagnosis, prognosis, and treatment
- Signed and dated by the reviewing doctor
- Returned as a PDF alongside the standard certificate where required
All documentation reflects the clinical assessment of the information provided at the time of review. Final acceptance is determined by the relevant insurer, which applies its own internal claims policies.
How to Get an Insurance Medical Certificate Online
Check what your insurer requires
Review your insurer’s claim documentation requirements carefully. Note whether they require a general doctor’s letter, a specific form, or particular details such as a prognosis or confirmation of fitness to travel.

Get Started →Frequently Asked Questions
Will my insurer accept a private medical certificate from MedicalCert?
Most UK insurers accept medical documentation signed by a GMC-registered doctor, which is what MedicalCert provides. However, final acceptance is at the discretion of your insurer, and some may 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. MedicalCert’s doctors can issue retrospective certificates where you can provide sufficient evidence of when you became unwell, such as prescription records, hospital letters, or pharmacy records. The reviewing doctor will assess whether a retrospective certificate is clinically justified based on the evidence provided. If the evidence is insufficient to support a retrospective certificate, 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, you can upload it during the consultation process. The reviewing GMC-registered doctor will complete the form to the required standard where the clinical information supports doing so. 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 obligated to complete insurance forms or write letters for non-NHS purposes. Many practices have reduced or stopped offering this service due to workload pressures, or will only do so for registered patients with long waiting times and a private fee. 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 basis for the certificate. Useful evidence includes: prescription records or pharmacy receipts, hospital discharge letters, results letters from specialists or tests, a photo or video describing your 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.
Is a MedicalCert certificate the same as an NHS sick note?
No. An NHS Med3 fit note (sick note) is issued by an NHS clinician specifically for employment and statutory sick pay purposes. A MedicalCert certificate is a private medical letter or certificate issued by a GMC-registered doctor for non-NHS purposes such as insurance claims. The two serve different functions. Many insurers require a private doctor’s letter rather than, or in addition to, an NHS fit note — always check what your specific insurer requires.
