More than one in ten of the people going abroad on holiday do so without travel insurance, risking thousands in ruined plans and potential injuries.
The latest research from Sainsbury's Bank shows that 13 per cent say they have taken trips without travel insurance in the past 12 months, adding up to around 3.33 million people in total.
The research also found that it is those in the youngest and oldest age brackets who are least likely to take insurance, with 16-to-24 year-olds accounting for almost a quarter (24 per cent) of uninsured travellers.
This group is by far the largest (1.085 million), although the number of vulnerable elderly people failing to take out cover is also significant. The over-65s accounted for 14 per cent of the total number.
Karen Preston, travel insurance manager, recommended that people include travel insurance on their "to-do" list, along with buying new clothes and checking travel arrangements.
"Travel insurance is essential for anyone going abroad, even if they are just planning a long weekend," she said.
"Last year, we estimated that there could have been around 241,000 travel insurance claims for medical or hospital care alone."
Travel insurance can be bought on a single trip or annual basis, with single trip cover starting from £22. To read more about insurance, click here.
