Europe heatwave 2026: weather warnings in effect
Weather warnings have been issued across multiple European countries in June 2026, with temperatures significantly above seasonal averages forecast for parts of Southern and Central Europe, including France, Spain, Portugal, Italy, and Greece. The UK Met Office and European Centre for Medium-Range Weather Forecasts (ECMWF) track these events in real time.
For UK travellers heading to affected regions, understanding what travel insurance covers - and what it does not - is particularly relevant during periods of extreme heat.
GHIC: what it covers and what it does not
The Global Health Insurance Card (GHIC) replaced the European Health Insurance Card (EHIC) for UK residents after Brexit. It is free to obtain from the NHS and provides access to medically necessary healthcare provided by state healthcare systems in EU countries, at the same cost as a local resident (which in many EU countries means free or at reduced cost).
The GHIC does not cover: private medical treatment, medical repatriation to the UK, mountain rescue, non-emergency treatment, or ongoing treatment for pre-existing conditions that is the primary reason for travel. It should be treated as a backup, not a replacement for comprehensive travel insurance.
The GHIC is free. Applications are made via nhs.uk. Be aware of commercial websites that charge for GHIC applications - the official application is free of charge.
Does travel insurance cover heat-related illness?
Coverage for heat-related illness varies by policy. Most comprehensive travel insurance policies cover emergency medical treatment for acute conditions, which would typically include heatstroke, severe dehydration, and heat exhaustion requiring hospital treatment. However, the policy wording matters.
Key questions to check in any travel policy:
- Does the medical emergency section explicitly include illness caused by environmental conditions?
- Is medical repatriation covered if hospitalisation abroad is extended?
- Are pre-existing conditions (including cardiovascular conditions that make heat more dangerous) declared and covered?
- Does the policy include a 24-hour emergency assistance line?
Pre-existing conditions and declaration
Travellers with pre-existing medical conditions must declare them accurately when purchasing travel insurance. Failure to disclose a relevant condition can render the entire policy void, not just the claim related to that condition, depending on policy terms. The Financial Conduct Authority (FCA) requires that insurers treat customers fairly, but non-disclosure remains a common reason for claim disputes.
The Financial Ombudsman Service (FOS) handles disputes between travellers and insurers where a claim has been rejected. The FOS is free to use for consumers.
FCDO travel advice and policy clauses
Most UK travel insurance policies include a clause that coverage may be affected if the Foreign, Commonwealth and Development Office (FCDO) advises against travel to a destination. It is important to check FCDO travel advice at gov.uk/foreign-travel-advice before purchasing and before departing. If FCDO advice changes after purchase, the position varies by policy.
Heatwave warnings from meteorological agencies are not the same as FCDO travel advisories. An ECMWF or Met Office heatwave alert does not automatically affect insurance coverage, but it should inform personal risk assessment.
Practical steps before travelling to a heatwave region
- Check FCDO travel advice for the specific destination
- Obtain a free GHIC if travelling to an EU country
- Read the medical emergency section of the travel policy - not just the summary
- Declare all pre-existing conditions accurately
- Save the insurer emergency assistance number to a mobile phone before travelling
- Note that 112 is the pan-European emergency number
