The winner of Alone UK 2023 was Tom Williams , a 39-year-old company director from Portsmouth. He lasted 34 days surviving alone in the Canadian wilderness and won the £100,000 prize after the last remaining competitor, Elise Wortley, tapped out.

Tom described winning as a "massive shock" and emphasized the mental challenge of survival and isolation. The competition featured 11 contestants who had to fend for themselves entirely alone, documenting their own experiences without any camera crew support.

Tom's victory and experience in Alone UK have been highlighted in multiple sources as a significant achievement in this extreme survival contest.
