Failing to declare any medical conditions could invalidate your travel insurance (Image: Getty) Brits are being warned to declare this one thing on their travel insurance or risk bills costing more than £150,000. Finding travel insurance is an important part of planning a holiday, providing financial protection if you run into any problems while away. It can be used to cover unexpected hospital bills, lost or stolen items, trip cancellations and even emergency transport.

Without the insurance these can be incredibly expensive when in another country. However, when applying for cover, failing to disclose any previous medical issues could completely invalidate your insurance. The Foreign Commonwealth and Development Office (FCDO) warned: “If you travel internationally you should buy appropriate travel insurance before you go, covering you for existing physical or mental health conditions (including those currently under investigation) and any activities you will be doing whilst you are away.

“If you do not have appropriate insurance before you travel, you could be liable for emergency expenses, including medical treatment, which may cost thousands of pounds.” function loadOvpScript(){let el=document.createElement('script');el.
