What is a travel advisory and how does it affect my insurance?
A travel advisory is government guidance about the risks of travelling to a country or region. In the UK these are the FCDO travel advice pages; most countries publish equivalents.
The levels of advice, broadly:
No specific warning — normal precautions.
Advise against all but essential travel to a country or a defined area.
Advise against all travel — the strongest level.
Advice is frequently geographically specific, applying to a border region or a city rather than a whole country, which matters enormously in practice.
The insurance consequence is the critical part. Almost all travel insurance policies exclude cover for travel to a destination against government advice. If the FCDO advises against all but essential travel and you go anyway, your policy will typically be void for that trip — not merely for incidents related to the risk described, but potentially entirely, including unrelated medical emergencies.
This is one of the most consequential exclusions in travel insurance and one of the least understood.
What happens if advice changes after you book:
Package holidays — if the organiser cancels because of official advice, you are entitled to a refund under package regulations. This is a strong reason to book packages for anywhere with elevated risk.
Independent bookings — airlines and hotels are not obliged to refund simply because advice changed, though many offer flexibility. Your insurance may cover cancellation if the policy includes it and the change occurred after you purchased the policy.
Buy insurance when you book, not before departure — cancellation cover only operates from the purchase date.
Other effects: consular assistance may be limited or withdrawn in areas with the strongest advice, and some employers and universities prohibit travel against it.
Check before departure as well as before booking, since advice changes, and sign up for email alerts on the destination page.
