Travel insurance is the least exciting thing you will buy for your trip, and the one you hope you never need. That is exactly why it gets skipped. Then something does happen, and that small box becomes the most important decision of the whole trip.
This guide explains travel insurance in plain English: what it covers, what it does not cover, how to compare policies, and when you can safely skip it.
What Travel Insurance Actually Is
Travel insurance is a simple promise. You pay a premium before you travel, and the insurer agrees to pay for specific problems, up to specific limits, under specific conditions. The limits matter, because a policy with a low medical limit can still leave you with a large bill.
Most policies are a bundle of separate covers: one for medical emergencies, one for cancellations, one for your bags. A single trip policy covers one holiday. An annual policy covers all your trips in a year.
What Travel Insurance Covers
Most comprehensive policies cover a similar set of problems.
Emergency medical treatment
If you fall ill or are injured abroad, it pays for hospital treatment, doctor visits, medicine and ambulance transport. The NHS does not pay for treatment abroad, and a European Health Insurance Card or a Global Health Insurance Card only covers state healthcare in certain countries. It is not a replacement for insurance, so check the official guidance on foreign travel insurance from GOV.UK first.
Trip cancellation
If you have to cancel before you leave, cancellation cover pays back money you have spent and cannot get back: flights, hotel deposits, tour costs, car hire. Cover only pays for specific reasons listed in the policy, such as illness, a death in the family, redundancy, jury service, or serious damage to your home.
Trip interruption and curtailment
This covers a trip that has already started. If you must come home early for a covered reason, the policy can pay for the unused part of your trip and the cost of getting home. Some policies also cover extra accommodation if you are delayed abroad.
Baggage and personal belongings
If your luggage is lost, stolen or damaged, baggage cover pays to replace it, up to a limit. There is usually a separate, lower limit for a single item, so a costly camera or laptop may not be fully covered. If your bags arrive late, the policy can pay for essential items while you wait.
Travel delay and missed departure
If your flight is delayed for a long time, many policies pay a set amount per period of delay, or pay for meals and accommodation. Missed departure cover helps if you miss your flight for a reason outside your control. Routine traffic jams usually do not count.
Personal liability and legal expenses
If you accidentally injure someone or damage their property, personal liability cover pays the costs. Many policies also include legal expenses cover, which helps with the cost of pursuing a claim against someone else.
What Travel Insurance Does Not Cover
A policy only pays for what it says it pays for.
- Pre-existing conditions you did not declare: claims linked to them will almost certainly be refused.
- Changing your mind: cancellation cover does not pay if you simply decide not to go.
- Known events: if a storm has been named or a strike announced before you buy, it is not covered.
- Alcohol and drug-related incidents: most policies exclude claims where alcohol or non-prescribed drugs played a part.
- Adventure activities without the right cover: skiing, scuba diving and bungee jumping are often excluded.
- Unattended belongings: a bag left on a beach or a phone in an unlocked car may not be covered.
- Travel against official advice: if your government advises against travel and you go anyway, most policies will not cover you.
- Pandemic-related cancellations: cover varies a lot between policies, so read the wording.
Medical Cover: The Part That Matters Most
If you buy travel insurance for only one reason, make it medical cover. Everything else is about money you have spent. Medical cover is about money you might have to spend, and the amounts are in a different league.
Compare three things. The medical expenses limit: the maximum the insurer will pay for treatment. The medical evacuation limit: check whether evacuation is covered at all. The excess: the amount you pay yourself on each claim.
Carry enough medication for the trip plus a few extra days, with a copy of your prescription. Travelling with older relatives? Our guide to travelling with grandparents covers the practical side of multi-generational trips.
Cancellation Cover: Getting Your Money Back
Cancellation cover is the part of the policy that most people actually use, because cancellations are far more common than medical emergencies. A parent falls ill, or a flight is cancelled and the hotel will not refund the deposit.
Check three things before you buy. The cancellation limit must be at least as high as the total non-refundable cost of your trip. Then the excess, which comes off every claim.
Buy your policy soon after booking, not the week before you travel.
Baggage, Delays and the Small Print That Decides Claims
Check the single item limit first: the most the insurer will pay for any one item. If your camera is worth more than this limit, it is not fully covered, even if the total baggage limit is higher.
Insurers ask for proof of ownership: receipts, photos or bank statements. Keep receipts for expensive items, and photograph your packed bag before you leave. If something is stolen, report it to the local police within 24 hours and get a written report.
For delays, check how long the delay must last before cover kicks in. Keep every receipt, plus your boarding pass.
Pre-Existing Medical Conditions: Declare Everything
A pre-existing medical condition is any health condition you had before you bought the policy. That includes conditions you take medicine for or have seen a doctor about.
When you buy a policy, the insurer will ask you about your health. Answer honestly and completely. If you leave something out, the insurer can refuse any claim linked to that condition. An undeclared condition can cost you the entire claim.
What happens when you declare a condition? The insurer covers it with no extra charge. The insurer covers it for an extra premium. Or the insurer excludes that condition from medical cover, but covers everything else. If it is excluded, consider a specialist insurer.
If your health changes between buying the policy and travelling, tell the insurer.
When You Can Safely Skip Travel Insurance
Travel insurance is worth it on most trips, but there are situations where skipping it is a reasonable choice.
- A short domestic trip with fully refundable bookings: there is little for insurance to protect.
- A trip you can afford to lose: if losing it would not hurt, you may choose to go without.
- Cover you already have: some bank accounts, credit cards and home insurance policies include travel cover. Check what yours includes first.
- A single day trip close to home: the risks are low and the costs of something going wrong are usually manageable.
The question is whether you could comfortably pay for it if it did.
How to Compare Policies: A Practical Checklist
Work through this checklist before you buy.
- Start with the medical limit: it should be high enough for your destination.
- Match the cancellation limit to your trip cost: add up everything non-refundable.
- Check the excess on each section: a low premium with a high excess is not a bargain.
- Read the exclusions: especially for activities, pre-existing conditions, and alcohol-related incidents.
- Check the activities you plan to do: skiing, diving and cycling often need extra cover.
- Confirm the destination is covered: some policies exclude certain countries.
- Look at the age limits: some policies charge much more above a certain age.
- Check the trip length limit: annual policies usually cap each trip at 30 to 60 days.
- Compare like with like: the cheapest policy is not always the cheapest for you.

Frequently Asked Questions
Do I need travel insurance for a holiday in Europe?
Yes, in most cases. A Global Health Insurance Card only covers state healthcare in some European countries, not private treatment, repatriation, cancellation, or your bags.
When should I buy travel insurance?
As soon as you book, or as soon as you make your first non-refundable payment. Cancellation cover starts from the day you buy the policy.
Does travel insurance cover pre-existing medical conditions?
It can, but only if you declare the condition when you buy the policy. If you do not declare it, claims linked to it will usually be refused.
What is the difference between single trip and annual travel insurance?
A single trip policy covers one holiday. An annual policy covers every trip you take in a year, usually with a limit on how long each trip can last.
Does my credit card or bank account include travel insurance?
Some do. Check the medical limit, the cancellation limit and the exclusions first, because free cover is often thinner than a bought policy.
What should I do if I need medical help abroad?
Call your insurer’s 24-hour emergency helpline as soon as you can, ideally before treatment. Keep every receipt and medical report for the claim.
Can I claim if my flight is delayed?
It depends on your policy and the length of the delay. Many policies pay a fixed amount after a delay of a set number of hours. Keep your boarding pass and receipts.
Is travel insurance worth it for a cheap holiday?
It depends on what you would lose. If the holiday is cheap, fully refundable and in your own country, you may reasonably skip it. Abroad, medical cover alone usually makes it worth it.
Travel insurance will not make your trip better, and it will not stop anything going wrong. What it does is put a limit on how bad a bad day can get. Buy it early, declare everything, and check that the limits match your trip.
