Cheapest travel insurance policies frequently exclude the situations most likely to require a claim — pre-existing conditions, certain activities, certain destinations. Slightly more spend (often £15-40 more) buys substantially better protection.
What cheap policies typically exclude
Pre-existing medical conditions undisclosed. Adventure activities (even hiking sometimes excluded). Specific countries (some Asian or African destinations not covered). Cancellation due to non-emergency reasons. Lost item coverage limited to under £200.
What slightly better policies cover
Pre-existing conditions if declared (specialist insurers: Free Spirit, World First, AllClear). Wide activity coverage. Most destinations. Cancellation for broader reasons. Lost items up to £1,500-3,000.
For a 2-week trip, the difference is typically £20-60. For the protection level, it's usually worth it. Cheapest insurance has the highest 'claim rejected' rate when actually needed.
