While planning a trip, the last thing you want is to get sick or injured before or during your trip. Unfortunately medical problems can come unexpectedly and can complicate your travel insurance claims. In these cases, a sick note is important to make sure that you are covered by your travel insurance.
In this blog we are going to learn about sick notes for travel insurance and answers to some frequently asked questions about it.
What Is A Sick Note For Travel Insurance?

A sick note for travel insurance, also known as a doctor’s note or a medical certificate, is a written statement by a licensed healthcare professional that says you are unfit to travel due to your illness or injury.
It usually includes information about your medical condition, how severe it is, and if you are able to go ahead with your planned trip.
Travel companies often require this document to process your claims related to illness, injury or other medical problems that are preventing you from travelling.
Sick Note vs Medical Report vs “Fit to Travel” Letter (Quick Clarity)
- Sick note / medical certificate: usually confirms you are not fit to travel (unfit to travel) for a defined period, due to illness or injury. Many insurers explicitly accept/require a medical certificate completed by your doctor for cancellation claims.
- Medical report / letter (often from abroad): if you need medical care while overseas, insurers commonly ask for a report / letter from the treating doctor / dentist abroad confirming the illness / injury and treatment.
- Fit to travel certificate: sometimes requested by airlines/tour operators or for return travel after a medical event. Requirements vary by provider and are not identical to travel insurance evidence. Always check what your insurer (and carrier) specifically needs.
Why You Might Need A Sick Note For Travel Insurance Claim:
There are many situations that can require a sick note to validate your travel insurance claims. These situations may include;
- Trip cancellations
- Delays or interruptions to your trip
- Medical treatment during your trip
- Travel insurance for pre-existing medical conditions
In practice, What Insurers Often Mean by “Medical Evidence”?
Depending on your policy and claim type, insurers frequently request a combination of:
- Medical evidence (medical certificate / doctor’s note; or treating doctor’s report abroad)
- Proof of travel and costs (booking invoice, travel tickets, itinerary, cost breakdown)
- Proof of cancellation/refunds (cancellation invoice showing refunds due for unused parts)
- Receipts for expenses incurred (medical, dental, taxi, ambulance, extra accommodation, etc.)

What Should a Sick Note Include?
A travel insurance sick note should be clear, legible, and specific enough to show why you could not travel, from when, and for how long.
In Ireland, medical certification commonly includes doctor identification details (for example, full name/signature and Irish Medical Council registration number).
Practical Checklist: Key Items to Ask Your GP / Medical Practitioner to Include
- Your name (matching your booking/policy)
- Date of assessment (consultation date)
- A statement that you are unfit to travel (or advised not to travel) due to illness/injury
- Relevant dates: when symptoms started (signs and symptoms), and the period you should not travel
- Doctor/clinic details and authentication (signature/stamp)
- Doctor’s Medical Council registration number (commonly used on Irish medical certs)
Privacy note: Some certificates use a general description rather than a detailed diagnosis. However, for insurance, providers may request more detail or follow-up reports to verify a medical diagnosis and severity. Share only what’s required by your insurer and policy terms.
Step-by-step: How to Make a Travel Insurance Claim Using a Sick Note
Step 1: Check Your Policy and Claim Section First
Different travel insurance policies have different terms and conditions, exclusions, and evidence requirements. Many insurers explicitly state you need proof you were unable to travel (such as a medical certificate) for cancellation claims.
Step 2: Notify the Insurer As Soon As Possible
Delays can create problems. Some policy wording sets strict expectations (for example, cancellation should be advised within a short window such as 48 hours or as soon as reasonably possible—this varies by insurer / policy).
Step 3: Get the Right Medical Evidence for Your Claim Type
Use this quick mapping:
|
Claim scenario |
Medical evidence that is commonly requested |
Other documents often requested |
|
Trip cancellation (before departure) |
Medical certificate/doctor’s note proving you were unable to travel |
Policy certificate + booking invoice + cancellation/refund breakdown |
|
Curtailment (cutting trip short) |
Treating doctor abroad report; sometimes GP report if a close relative at home is the reason |
Proof of unused parts/refunds; insurer may require authorisation via assistance service |
|
Medical treatment abroad (emergency medical expenses) |
Treating doctor/dentist report abroad confirming illness/injury |
Receipts/invoices; sometimes EHIC (E111) copy requested in claim packs |
Step 4: Contact Medical Assistance if Required (Especially Abroad)
Some Irish providers recommend contacting their 24/7 medical assistance before receiving treatment, where possible. This can help with authorisations, referrals, and arranging care.
Step 5: Submit a Clean, Complete claim pack
A common reason for the claim stall is missing paperwork. For many insurers, a “complete” file includes:
- policy certificate
- booking invoice / travel dates and costs
- cancellation/curtailment invoice showing refunds (if relevant)
- medical certificate or treating doctor report
- receipts for expenses incurred
Pre-existing Medical Conditions: Why the Sick Note Alone May Not Be Enough
If your claim relates to a pre-existing medical condition, insurers often expect that condition to have been declared and sometimes “medically screened” when you bought the policy (often at the time of booking the trip / when getting your quote online). If you do not comply with medical declarations, insurers may refuse or reduce claims. This is a common policy position across providers.
Practical tip: If you have any ongoing conditions, recent tests, planned surgery, or medication changes, treat this as a medical screening/declaration topic and document what you disclosed and when.
Common Mistakes That Can Lead to Delays or Rejected Claims
- The note doesn’t clearly say you were unfit to travel (or lacks dates).
- Using the wrong clinician when the insurer requires the “usual GP” for cancellation.
- Late notification to the insurer (some policies impose tight reporting expectations).
- Missing booking/cancellation invoices or refund details (insurers calculate loss after refunds).
- Not contacting emergency assistance where the policy expects authorisation/support (especially for curtailment or major medical expenses).
- Pre-existing condition not declared / not screened (can invalidate cover for related claims).
Final Thoughts
A sick note is not just a formality, it is an important piece of document that determines whether your travel insurance claim gets approved or rejected. Whether you are cancelling a trip due to illness, claiming for medical expenses abroad, or dealing with trip delays, a sick note acts as formal medical evidence that supports your claim.
Next best action: Check your travel insurance policy wording and claim form requirements (especially around “usual GP,” medical screening, and timelines), then gather the medical certificate and supporting documents in one complete pack before you submit.
