Travel insurance and Foreign Office travel advice

The Foreign, Commonwealth and Development Office (FCDO) publishes travel advice for every country, and that advice has a direct effect on your travel insurance. If the FCDO advises against all travel, or against all but essential travel, to your destination, then with the vast majority of policies you invalidate the cover by going anyway¹. That means no medical expenses cover, no cancellation cover and no baggage cover while you are there, even if you paid the premium in full.

The timing matters as much as the advice itself. Advice that was already in place when you booked or bought the policy is treated very differently from advice issued after you have booked, and differently again from advice that changes while you are already abroad. This page explains each situation, what you can claim, and where to go if an insurer refuses.

Travelling against FCDO advice usually voids your cover

The FCDO grades its advice country by country, and sometimes region by region. When it advises against all travel, or against all but essential travel, that advice is written into the way travel insurance works. BIBA's guidance is blunt: if you travel to a country despite FCDO advice against "all but essential" international travel, then your travel insurance policy is unlikely to be valid¹. Which? reports the same from the insurer side: with the vast majority of travel insurance policies, travelling to a destination the FCDO advises is unsafe means "you'd be invalidating the policy because you'd be travelling against government advice"².

The practical effect is wider than many people expect. Going against the guidance does not just remove cover for risks connected to the reason for the advice, such as war or unrest. It can invalidate the whole policy, leaving you unprotected for anything that happens on the trip: an accident, an illness, a theft, a delayed flight³. A medical emergency abroad can cost tens or hundreds of thousands of pounds to treat and to fly you home, and with no valid policy that bill falls on you and your family.

Some insurers carve out narrow exceptions. Aviva's policies may cover trips to areas the FCDO warns against, provided the trip is deemed essential, typically a family emergency or another urgent matter, with no cover for holidays or leisure travel³. Admiral has said customers who buy its travel insurance would be covered for injuries suffered as a result of hostilities, but only assuming the FCDO had not advised against travel before the customer left the UK³. These exceptions are insurer-specific and narrow. The only way to know where you stand is to read the policy wording and, where it is unclear, ask the insurer in writing before you travel.

Two further points are worth checking in your own wording. BIBA's checklist notes that you will not get cover if you have been advised against travelling, among other circumstances such as being in the last two months of pregnancy or travelling to obtain medical treatment abroad⁷. And government guidance reminds people that foreign travel insurance is not intended to cover you if you live abroad permanently, so a UK policy is built around UK residents making trips⁸. The dedicated page on how travel insurance works explains the main sections of cover and what each one pays for.

Buy travel insurance before you go

The FCDO question is one reason timing matters, but there are several others, and they all point to buying cover early rather than at the airport. ABTA's guidance is that the vast majority of insurance providers require you to be in the UK when you buy your policy, and if you buy it when you are already overseas, it will invalidate it⁹. Which? puts the same point more starkly: if you forgot to take out travel insurance before your trip and buy it while on your foreign holiday, most policies are likely to be void and you will not be able to claim should the worst happen¹⁰.

Buying late also strips out the cover you most need. Cancellation cover, for example, is unlikely to be included if you are purchasing a policy just hours before your flight, because the events that would cause you to cancel have usually already happened or become known by then¹⁰. ABTA's advice to holidaymakers is to buy appropriate insurance at the time of booking, so your money is protected if you have to cancel, and its guidance on cancellation fees makes the same point: purchase travel insurance when you make the booking, so that if you have to cancel you may be able to claim via your insurance policy¹¹.

For travel to the EU, government guidance is that travellers need travel insurance before they go away, and that they need to understand the terms and conditions of their policy and be satisfied with its cover for healthcare and travel disruption¹³. A European health insurance card is not a substitute: the page on travel cover and the GHIC explains what the card does and does not pay for. The page on when to buy travel cover goes through the timing question in detail.

One rule inside the policy is easy to miss and matters if things go wrong. Many policies require the policyholder to contact the insurer or its assistance company before incurring medical expenses abroad. The Financial Ombudsman Service has said it does not think a customer's claim automatically fails just because they did not contact the insurer first¹⁴, but calling the number on your policy as soon as a problem starts is what protects the claim. The page on making a claim sets out the steps.

When advice changes after you have booked

Advice that changes after you have booked is treated differently from advice that was already in place, and the difference decides whether you have a claim. If the FCDO changes its advice to recommend against "all travel" or "all but essential travel" to the country you are currently in, or the country you are due to visit, cover typically responds for costs as a result of cutting your trip short, including additional accommodation and travel expenses to get home safely³. The same principle applies to cancellation before you leave, depending on the policy's wording.

Where the advice sits in the sequence of booking, buying the policy and travelling usually decides the outcome of a claim.

The contrast with advice that was already in place is sharp. Admiral has said that if the advice not to travel to a destination was already in place when the customer bought the policy, even if the war had not yet reached it, there would be no cover³. In other words, the insurer's promise is about change, not about the situation itself: the policy responds when the FCDO advice moves against you after you have committed, not when you chose to book into a known risk.

Changes while you hold the policy are not limited to FCDO advice. Once you buy travel insurance, you must tell the insurer if there are any changes in your health or condition¹⁷. Which? reports the same rule across the board: your insurer must be told of changes after buying a policy, including new medical conditions, changes to medication, amended travel dates, different accommodation or adding extra travellers, or a claim could be rejected even if the issue seems unrelated¹⁸. The page on telling your insurer about changes lists what counts.

Where a significant change in health leads someone to cancel and the insurer disputes the claim, the ombudsman has a specific remedy it may apply: if the customer goes on the holiday with cover elsewhere, it might think it fair for the current insurer to pay the difference in premium charged by the new insurer, up to the value of what any holiday cancellation claim would have been at the time of the significant change in health¹⁹. Since April 2021, consumers offered a travel insurance policy with a £100 or more additional premium due to a medical condition must be signposted to specialist help finding cover²⁰. The page on travel insurance with medical conditions explains that route.

Finally, a limit that catches people out: cover is usually provided only if a cancellation or missed flight is caused by a specific insured event. The ombudsman's guidance is that if you change your mind about travelling or miss your flight, your insurance may not cover you²¹.

All travel or all but essential travel: how cover differs

The FCDO uses two levels of warning, and policies tend to treat them the same way. Advice against "all but essential travel" still permits essential journeys, and advice against "all travel" permits none, but for insurance purposes both usually switch the policy off. ABTA Travel Insurance, for example, covers travel to destinations worldwide, providing there is no advice in place from the FCDO advising against all travel or all but essential travel²². The distinction between the two levels matters for whether you may lawfully or sensibly make an essential trip, not for whether a holiday is covered: a holiday is never essential.

What differs between insurers is the treatment of genuinely essential travel. Aviva's policies may cover trips to areas the FCDO warns against, provided the trip is deemed essential, typically family emergencies or other urgent matters, with no cover for holidays or leisure travel³. That is an exception, not the market norm, and it depends on the insurer being told and agreeing before you travel.

What no policy covers is disinclination. BIBA's guidance for travellers with mental health conditions states the general rule: deciding that you no longer want to travel, called disinclination to travel, is not covered under travel insurance²³. Cancellation is likely to be covered if a medical professional deems you unfit to travel owing to your anxiety, or in circumstances such as an unexpected medical emergency occurring that stops you from travelling²³. The FCDO advising against travel is a separate, policy-specific trigger, and the next section covers it.

Cancelling a trip because of FCDO advice

When the FCDO advises against travel after you have booked, your route to a refund depends first on what you booked. If you have a package holiday and the FCDO advises against travelling to your destination, you are entitled to cancel without paying any fees and get a full refund, or be offered an alternative holiday⁴. That right sits with the tour operator, not with your insurer, and it applies whether or not you have travel insurance.

For flight-only bookings the position is narrower. Airlines are obliged to refund you if they cancel your flight, but they are not automatically cancelling flights when the FCDO changes its advice, so a flight that still departs leaves you choosing between travelling against advice or losing the fare unless the airline offers flexibility⁵. Travel insurance may then pick up costs you cannot recover elsewhere, if the policy covers FCDO advice changes, which is exactly why the timing rules in the previous section matter.

Work down the chain: the organiser or airline first, insurance for what is left, and the ombudsman if a claim is refused.

The ombudsman's case files show how this plays out in practice. In one published case study, a cruise was cancelled by the tour operator because the Foreign and Commonwealth Office was advising against all but essential travel due to the pandemic, and the customer sought a refund of the insurance premium²⁵. The detail worth noting is that the operator cancelled the cruise: where the FCDO advice leads the travel company to cancel, your money comes back from the company, and the insurance claim is about anything the company will not refund.

If you have no travel insurance at all and have to cancel, ABTA's guidance is down to you to buy appropriate insurance at the time of booking, because that is what ensures your money is protected if you have to cancel¹¹. Without it, you are relying on the travel company's goodwill or its terms. One further protection depends on where you book from: if you book your holiday from outside the UK, protection against the tour operator's financial failure might not apply unless the operator opted to voluntarily protect your holiday, so you must enquire with your travel company²⁶. The page on travel insurance cancellation cover explains what a cancellation section pays for and the page on rejected claims what to do when one is turned down.

Complaints and where to get help

If an insurer refuses a claim that you believe should be paid, there is a free, independent route to challenge it. The Financial Ombudsman Service can help with complaints about insurance for when you travel to another country, alongside other insurance and banking products⁶. When it investigates a travel insurance complaint, it checks what the policy says and what type of cover is offered, to decide whether you have been treated unfairly²¹. If it thinks the insurer unfairly turned down a claim, it may recommend that the insurer reconsider the claim in line with the terms and conditions of the policy, or pay the claim and add interest to cover the period from the date of the claim until the date the settlement is paid²⁷.

The process starts with the insurer, not the ombudsman. Complain to the insurer first and give it the chance to respond; if you are not satisfied with its response, you can take the complaint to the ombudsman²⁸. Where the complaint is about the sale of the policy as well as the claim, the ombudsman usually looks into the complaint about the claim first before considering any complaint about a mis-sale²⁸. If it finds the policy was mis-sold, it can ask the insurer to pay the claim where the customer would have bought a different policy that would have covered it²⁸, and for inadequate sale information it might ask the insurer to refund any set up or cancellation fees, provide a pro-rata refund of the policy premium, and pay the extra costs of arranging new cover²¹.

Travel insurance complaints are a significant and growing part of that workload. The ombudsman received 996 travel insurance complaints in the first quarter of 2025/26²⁹, rising to 1,300 cases in the first quarter of 2026/27, up 30% (300) year-on-year and up slightly on the previous quarter's 1,200 complaints³⁰. Across the whole of 2025/26 it recorded 4,451 travel insurance complaints³¹, within a total of 42,897 insurance complaints between 9 July 2024 and 8 July 2025³². The ombudsman has also reminded consumers that if a financial firm refuses a refund and the consumer disagrees, it can look into a complaint³³.

For help finding cover in the first place, BIBA operates a signposting service for people with medical conditions, and insurance brokers offer a free and easy-to-use complaints service via the ombudsman if things go wrong²⁰. The page on complaining about an insurer sets out the full process and time limits, and the page on using a broker or buying direct explains how a broker can help with unusual destinations or circumstances.
