Travel insurance claim letter and document checklist for illness

If illness stopped your trip, insurers commonly ask for your booking confirmation, cancellation invoices, receipts, your policy number and medical evidence showing when you fell ill and that you were unfit to travel. This tool builds that checklist for your situation and drafts a claim cover letter. Always read your own policy wording first.

A document checklist and draft cover letter for an illness claim.

Step 1 of 4: What happened

What happened?

Fell ill on the day you were due to leave? Choose the cancelled or missed flight card, whichever matches what you did.

How to use this tool

  1. Pick what happened: you cancelled before the trip, came home early, missed a flight, or needed treatment abroad.

  2. Add the key dates: when the illness started, when a doctor saw you, and when you cancelled, travelled home or were treated.

  3. List your costs and say whether the airline, hotel or travel company has refunded anything.

  4. Add your policy number and insurer name if you have them. Leave blanks if not; the letter keeps a placeholder.

  5. Read the flags, tick off the checklist, then copy or download the draft letter and edit it in your own words.

  6. Check everything against your policy wording before you send it.

What does a travel insurance claim for illness usually involve?

Most claims follow the same pattern. You tell the insurer what happened, show what you lost, and prove that illness caused it.

The insurer reads your evidence against the policy wording. That wording sets what is covered, the limits, the excess and any time limit for claiming. Two policies with the same name on the front can work very differently inside.

Ireland's Competition and Consumer Protection Commission advises keeping all documents and receipts that support your claim. It also says you must meet the policy conditions before you can claim. So the work splits in two: gather the paperwork, then match it to your policy.

Which documents do insurers commonly ask for?

Insurers commonly ask for proof of the trip, proof of the loss, proof of payment and medical evidence. The exact list depends on your policy and on what happened. The table shows the documents this tool suggests for each situation.

Treat this as a starting list. Your insurer may ask for less or for more, such as translations or a copy of your passport.

Do I need a doctor's note to claim on travel insurance?

In most illness claims, yes. Insurers commonly ask for medical evidence that shows two things: when the illness started, and that it stopped you travelling on the dates in question.

The strongest evidence usually comes from a doctor who saw you at the time. That might be your own doctor, an urgent care clinic, a hospital, or the doctor who treated you abroad. Their notes record the date, what they found and any advice not to travel.

Some insurers send their own medical form for your doctor to complete. Others accept a letter or certificate. Check your claim form or ask the claims team which they want before you pay for anything.

Can a medical certificate be backdated for an insurance claim?

No. A doctor can only certify what they assess, on the date they assess it. A note written later can record what you told the doctor about earlier days, but its own date stays the date it was written.

This matters for insurance. Insurers may want evidence dated at the time you were ill, because it links the illness to the cancellation or early return. If you only see a doctor afterwards, say so honestly in your claim. Ask the doctor to write when they first saw you, what they found and what you reported.

Never change a date on a document or ask anyone to. False information can cost you the claim and the policy.

What should I do first if I fall ill before or during a trip?

Look after your health first. Then protect your claim with a few early steps.

  • If you are abroad and need treatment, call your insurer's emergency assistance line as soon as you can. Ireland's consumer protection body notes that some policies ask you to contact the medical or emergency helpline as soon as possible after an incident.
  • See a doctor while you are ill, so the record shows the date and their findings.
  • If you have not left yet, contact the airline, hotel or tour operator. Ask what they will refund and get the answer in writing.
  • Keep every receipt, booking email and message.
  • Read the cancellation or medical section of your policy before you spend money on new flights.

The same body warns that if you travel against a doctor's advice, you may not be covered. If a doctor tells you not to travel, follow that advice and ask them to put it in writing.

Why do insurers ask whether you claimed a refund elsewhere?

Because many policies only pay for money you cannot get back. The UK Financial Ombudsman Service says most travel insurance policies do not cover losses that can be recovered from another source.

The Ombudsman suggests asking the airline or travel provider for a refund or compensation first. If they refuse, ask them to confirm in writing why they will not pay. That letter often becomes part of your claim pack.

For flights, check what kind of refund applies:

  • Under EU air passenger rules, when the airline cancels your flight, it must offer a choice between a refund and rerouting.
  • When you cancel or miss a flight yourself because you are ill, those cancellation rights do not apply in the same way. Your fare rules decide what you get back.
  • The EU's official guidance also lists not taking the outbound flight of a return booking as a case where the airline may refuse you on the return. If you miss your outbound flight, call the airline before you rebook.

For package holidays, the EU's official guidance says you can end the contract before the trip starts, but the organiser may deduct a reasonable fee from your refund. Your insurer will usually want the organiser's statement showing what you lost.

Does the EHIC or GHIC replace travel insurance?

No. The European Health Insurance Card gives you the same access to public healthcare as people insured in the country you are visiting, for care that cannot wait until you get home. The UK Global Health Insurance Card works in a similar way in the countries it covers.

Both cards have clear gaps. Official EU guidance says the EHIC does not cover private healthcare, planned treatment, or rescue and repatriation. The NHS says the UK GHIC is not a replacement for travel insurance and does not cover being flown home, private treatment or ski and mountain rescue. It also will not cover costs that a local resident would have to pay.

If you paid for public care abroad, EU guidance says you can ask the national institution in that country for a refund while you are there, or your own health insurer when you get home. Refunds follow the rules and rates of the country where you were treated. Your travel insurer may ask whether you used your card or claimed this refund, so keep the paperwork.

What if I had a health condition before I bought the policy?

Read the health section of your policy carefully. Many policies treat existing conditions differently from new illness.

Ireland's consumer protection body says many policies do not cover existing conditions that flare up abroad unless you told the insurer in advance and they accepted the risk. It warns that if you do not disclose a condition, a claim may be invalid. It also says an insurer cannot refuse to pay because of a genuine mistake when you applied.

The UK Financial Ombudsman Service explains that some policies ask you to tell the insurer about a change in your health after you buy the policy, sometimes even while you wait for a diagnosis. If you paid for the trip after such a change and did not report it, the insurer may only cover payments made before the change.

Answer every health question on the claim form honestly. If you are unsure whether something counts, ask the insurer.

What does the cover letter need to say?

A claim cover letter is a short summary that sits on top of your documents. It helps the claims handler see the whole story in one page.

A clear letter usually includes:

  • Your name, address, policy number and any claim reference.
  • The trip: dates, destination, booking reference and who travelled.
  • What happened, in date order: when you fell ill, when you saw a doctor, and when you cancelled, travelled home or were treated.
  • What you are claiming, with amounts, and any refunds you already received.
  • A list of the documents you have attached.
  • A line saying you are happy to provide more information.

Keep the medical detail short. Your doctor's evidence carries the diagnosis. Stick to facts and dates, and do not guess at what your policy covers.

Three example claim cover letters

These are invented examples. The names, dates and amounts are not real. Use them to see the shape of a letter, then write your own.

Example 1: Cancelled before the trip because of illness

Dear Claims Team,

Policy number: [Policy number] Booking reference: [Booking reference]

I am writing to claim for the cancellation of a trip to Lisbon booked for 14 to 21 March 2026 for myself and one other person.

On 9 March I developed a high fever and a cough. My doctor saw me on 10 March and advised me not to travel. My symptoms continued, and I cancelled the booking on 11 March.

The flights cost EUR 412.00 and the apartment cost EUR 690.00. The airline refunded EUR 58.00 in taxes. The apartment host refunded nothing, and their written reply is attached.

I am claiming EUR 1,044.00 before any excess.

I have attached the booking confirmations, card statement, cancellation emails, the host's refusal and my doctor's note dated 10 March.

Please let me know if you need anything more.

Yours sincerely, [Your name]

Example 2: Came home early because of illness

Dear Claims Team,

Policy number: [Policy number] Assistance reference: [Assistance reference]

I am claiming for cutting short a holiday in Crete planned for 2 to 16 June 2026.

On 7 June I developed severe stomach pain and attended a local clinic the same day. The doctor advised rest and a check with my own doctor at home. I called your emergency assistance line on 7 June and was given the reference above. I flew home on 9 June.

I am claiming for the unused 7 nights of accommodation, EUR 560.00, and the new flight home, EUR 248.00. My original return flight could not be refunded.

Attached are the booking confirmation, the clinic report and bill, the new flight receipt, my card statement and the airline's written reply.

I can send translations or further details if needed.

Yours faithfully, [Your name]

Example 3: Medical treatment abroad

Dear Claims Team,

Policy number: [Policy number] Claim reference: [Claim reference]

I am writing to claim medical costs from a trip to Kraków from 20 to 25 April 2026.

On 22 April I twisted my ankle badly and could not walk on it. After calling your assistance line, I was seen at a public hospital that afternoon. I showed my EHIC there. I still paid a patient fee of PLN 180.00 and PLN 64.50 for medicines.

I am claiming PLN 244.50 before any excess. I have not received any refund from a public health system for these costs.

I have attached the hospital discharge note, both receipts, a copy of my EHIC and my booking confirmation.

Please contact me if you need more information.

Kind regards, [Your name]

Worked example: a cost summary before you send the claim

This example is hypothetical. It shows how the tool adds up a cancellation claim. It does not depend on any law or policy.

Marta fell ill two days before a city break. She cancelled and listed three costs:

Marta's cancellation costs
CostAmountRefund statusRefundAmount she may claim before excess
FlightsEUR 320.00Refund receivedEUR 40.00EUR 280.00
HotelEUR 450.00Refused in writingEUR 0.00EUR 450.00
Museum ticketsEUR 36.00Not asked yetEUR 0.00EUR 36.00
TotalEUR 806.00EUR 40.00EUR 766.00

The tool shows EUR 766.00 as the amount she may claim before any excess. It flags the museum tickets, because she has not yet asked for a refund. Many policies do not pay for losses you can get back elsewhere, so she asks the museum first.

Her doctor saw her on the day she cancelled. The tool adds "medical evidence of when the illness started" and "medical evidence that you were unfit to travel" to her checklist. The insurer then takes off the excess shown in her policy.

What if my claim is turned down?

Ask the insurer to explain the decision in writing and to name the policy term it relied on. Then check that term in your wording.

If you still disagree, make a formal complaint to the insurer. In the UK, the Financial Ombudsman Service says you can bring the complaint to it if the company does not send a final response within eight weeks. Its service is free, and it may ask for your policy certificate or terms.

In Ireland, the Financial Services and Pensions Ombudsman says you need to complain to your provider first. Its service is also free. Other countries have their own financial ombudsman or complaints body; your policy documents usually name it.

Ireland's consumer protection body also notes that an insurer cannot automatically refuse a claim just because you told them late, if the delay did not harm the insurer.

When to see a doctor straight away

Get urgent help, not a claim form, if you or someone with you has:

  • Chest pain or pressure, or sudden breathlessness.
  • Sudden weakness, numbness, a drooping face or trouble speaking.
  • A seizure, fainting or confusion.
  • A high fever with a rash that does not fade, a stiff neck or drowsiness.
  • Severe bleeding, a serious injury or a head injury.
  • Signs of severe dehydration, such as no urine for many hours, dizziness and a dry mouth.

In the EU, call 112. In the UK, call 999. If you are abroad and it is not an emergency, call your insurer's assistance line, which can usually point you to a suitable clinic.

How getmedicalcertificate.com can help

If you need written evidence that you were ill, you can request a general medical certificate. A doctor reviews your case first, and you pay only after that review. The price is EUR 34.99 with no added fees at checkout. If the doctor cannot issue a certificate, you get a full refund.

When a certificate is issued, you receive a signed PDF, usually within about 30 minutes of the doctor's approval. It carries a reference code anyone can check, including an insurer. Certificates are issued in English, and we cover 42 countries in Europe.

Be aware that a certificate cannot be backdated, and some insurers want evidence dated at the time you were ill. Check your policy first. An unfit to travel certificate is planned.

Frequently asked questions

Insurers commonly ask for your policy number, the booking confirmation, proof of payment, cancellation invoices or receipts, and medical evidence showing when the illness started and that you could not travel. Treatment abroad usually adds itemised bills and a report from the treating doctor. Your own policy wording decides the exact list, so read it before you send anything.

Usually yes. Insurers commonly want medical evidence that shows when the illness began and that it stopped you travelling on your booked dates. Evidence from a doctor who saw you at the time is often the strongest. Some insurers send their own medical form for your doctor. Check your claim form or ask the claims team what they accept.

No. A certificate carries the date the doctor assessed you. A doctor can record what you said about earlier days, but cannot date the document earlier. Insurers may want evidence from the time you were ill. If you only saw a doctor afterwards, say so honestly and ask the doctor to state when they first saw you.

Many policies only pay for losses you cannot recover elsewhere. The UK Financial Ombudsman Service says most travel insurance policies do not cover losses that can be recovered from another source. Ask the airline or travel company for a refund first, keep their answer in writing, and claim only the amount you lost after any refund.

Some policies cover missed departure or cancellation caused by illness; others do not. Read the relevant section of your policy. Keep medical evidence from the day, your flight details and receipts for any new ticket. EU guidance notes that missing the outbound flight on a return booking can lead the airline to refuse you on the return, so call the airline first.

No. Official EU guidance says the European Health Insurance Card does not cover private healthcare, planned treatment, or rescue and repatriation. The NHS says the UK GHIC is not a replacement for travel insurance and does not cover being flown home. Both cards only give access to public healthcare on the same terms as local residents.

Where you can, yes. Ireland's Competition and Consumer Protection Commission notes that some policies ask you to contact the medical or emergency helpline as soon as possible after an incident. In an emergency, get care first and call as soon as you are able. Write down the reference number you are given and add it to your claim.

It may affect your claim. Ireland's consumer protection body warns that if you do not disclose a condition, a claim may be invalid, though an insurer cannot refuse to pay because of a genuine mistake. Read the health section of your policy and answer the claim form honestly. If unsure, ask the insurer how they will treat it.

In the UK, the Financial Ombudsman Service says that if the company does not send a final response within eight weeks, you can bring your complaint to the Ombudsman. The service is free. In Ireland, you must complain to your provider before going to the Financial Services and Pensions Ombudsman. Check your policy for the complaints body in your country.

Usually, yes. The excess is the first part of a claim that you pay yourself. Ireland's consumer protection body says it is usually a fixed sum and suggests checking the amount with your provider. This tool shows totals before any excess, because the amount and how it applies depend on your policy.
