Do You Need a Medical Certificate to Claim Travel Insurance?

Key points

  • Most UK travel insurers require a medical certificate to process cancellation, curtailment, or medical expenses claims
  • The certificate must be signed by a GMC-registered doctor — a self-certification or GP letter of facts is usually not sufficient
  • There are two distinct types: a cancellation certificate (pre-departure illness) and an overseas medical report (illness abroad)
  • NHS GPs can legally decline to complete insurer claim forms — a private certificate from a registered doctor is the practical alternative
  • Without a valid certificate, your claim is likely to be rejected

If you have had to cancel a holiday, cut a trip short, or receive medical treatment abroad, your travel insurer will almost certainly ask for medical evidence before paying out. For the vast majority of health-related travel insurance claims, the answer is yes — a medical certificate is required. Without it, most insurers will reject or delay your claim.

This guide explains exactly when a certificate is needed, what it must contain, why your NHS GP may not be able to help, and how to get the right documentation quickly.

When Do Insurers Require a Medical Certificate?

Travel insurance policies cover a range of scenarios — and different claim types require different documentation. Medical evidence is typically required for:

Cancellation due to illnessYou became unwell before departure and could not travel. Your insurer needs a certificate confirming the illness prevented travel, the onset date, and your unfitness to travel.
Trip curtailment (cutting short)You fell ill during your trip and had to return home early. Your insurer needs medical evidence confirming it was medically necessary to end the trip.
Medical expenses abroadYou received treatment overseas and are claiming back costs. Insurers require receipts plus a medical report confirming the illness, diagnosis, and treatment received.
Cancellation due to a family member’s illnessA close relative became too ill for you to travel. The certificate must be for the family member’s condition, confirming how it prevented your trip.
Check your specific policy first. Some insurers send their own claim form for the doctor to complete rather than accepting a free-text letter. Before obtaining a certificate, check whether your insurer has a specific form — and if so, whether a private certificate will be accepted or whether the insurer’s own form is mandatory.

What Must a Medical Certificate Contain?

For a medical certificate to be accepted by a UK travel insurer, it must include specific information. A generic GP letter or “statement of facts” is often rejected because it describes your medical history rather than providing a clinical assessment of your fitness to travel.

What a valid travel insurance medical certificate must include

  • Your full name and date of birth
  • The specific medical condition — the diagnosis or clinical description, not just “unwell”
  • Onset date — when symptoms began, to demonstrate the illness arose after the policy was purchased
  • A clinical assessment confirming you were unfit to travel (for cancellation claims) or that early return was medically necessary (for curtailment claims)
  • Expected recovery timeline — how long you were or would be unfit
  • Signature and GMC registration number of the issuing doctor
A “statement of facts” from your GP is not the same thing. Some NHS GPs offer a statement of facts as an alternative to a clinical assessment — this is a factual summary of your medical records, not a clinical opinion on your fitness to travel. Many insurers explicitly require a clinical assessment and will reject a statement of facts. If your GP offers this instead of completing the claim form or issuing a certificate, it may not satisfy your insurer’s requirements.

Why Your NHS GP May Not Be Able to Help

A common frustration when making a travel insurance claim is that NHS GPs can — and frequently do — decline to complete insurer claim forms or issue travel insurance certificates. Completing private medical certificates and insurer forms falls outside the NHS contract. It is private work that GPs are entitled to decline, charge for, and take up to 30 days to complete where they do agree.

That 30-day turnaround is incompatible with most insurer claim filing deadlines. Many policies require you to submit documentation within 28 days, or within a shorter window if claiming for an emergency abroad.

Pre-Departure vs Abroad: Two Different Certificates

Many people assume one document covers everything. In practice, the certificate needed depends on when and where the illness occurred.

Cancellation certificate — for illness before you travel

If you became ill in the UK before your departure date, your insurer needs a certificate from a UK-based GMC-registered doctor confirming the illness prevented travel. This is issued based on a clinical assessment of your condition — either at the time of illness or retrospectively if you are applying after the fact.

Overseas medical report — for illness while abroad

If you fell ill during your trip, your insurer will typically require documentation from the treating doctor abroad confirming the illness, diagnosis, and treatment received. In some cases, they also ask for a supporting letter from a UK doctor — particularly for curtailment claims where the decision to return early was made remotely.

Keep everything from abroad. If you receive treatment overseas, ask the local doctor or hospital for a written medical report and keep all receipts and invoices. Many insurers will not process an expenses claim without this documentation, and obtaining it retrospectively after you return is significantly harder.

Does the Certificate Need to Be from Your Own GP?

No. UK travel insurers require a certificate from a GMC-registered doctor — they do not specify that it must be from your registered NHS GP. Any GMC-registered doctor who conducts a clinical assessment and issues a certificate meets the standard insurers require. The issuing doctor’s GMC number is included on the certificate and is verifiable by the insurer directly.

The key requirement is clinical assessment — the doctor must have reviewed your case and formed a clinical opinion, not simply recorded a statement of facts from your medical records.

Can Your Claim Be Rejected Without a Certificate?

Yes — and this is the most common reason health-related travel insurance claims are denied. If you submit a claim for cancellation due to illness without a valid medical certificate from a GMC-registered doctor, your insurer has grounds to reject it regardless of how genuine your illness was. The certificate is the evidence that converts your account of events into clinical documentation the insurer can rely on.

Timing — How Quickly Do You Need to Act?

Most travel insurance policies impose a time limit on submitting claims and supporting documentation. Common deadlines are 28–31 days from the cancellation date, or from the date you return from an interrupted trip. Some policies have shorter windows — particularly for medical expenses abroad where prior authorisation was expected but not obtained.

Do not wait until you have fully recovered to obtain documentation. A certificate can be issued during your illness or shortly after, while the clinical picture is still clear. Applying weeks later with no contemporaneous evidence makes the clinical assessment harder and some applications may not be supported.

Pre-existing conditions and timing: If the illness that caused your cancellation is a pre-existing condition you did not declare when purchasing the policy, your claim is likely to be rejected regardless of the medical evidence you provide. The certificate establishes what the illness was and when it began — if the insurer determines that onset predates the policy or that the condition was undeclared, the certificate alone will not save the claim.

What You Need to Claim Successfully

For most health-related travel insurance claims in the UK, you need:

  • A medical certificate from a GMC-registered doctor confirming the illness and its impact on your travel plans
  • The certificate to include: your name, condition, onset date, clinical assessment of unfitness to travel, and the doctor’s GMC number
  • Any receipts, invoices, or foreign medical reports for expenses incurred abroad
  • Your policy documents and booking confirmation showing the trip cost and cancellation penalties
  • The claim submitted within your policy’s filing deadline

If your NHS GP cannot complete the documentation in time, or declines to do so, a private travel cancellation certificate from a GMC-registered doctor provides the same clinical evidence your insurer requires — and can be obtained the same day.
