Claudia Winkleman is back with Celebrity Traitors UK season 2 on Thursday 1 October at 8pm. The has set the return on One and iPlayer, giving viewers a fixed start date after the first run drew 14.9m across the series and peaked at 15.4m for the finale.
The launch episode opens longer than usual, then the series moves to two nights a week on Thursday and Friday evenings at 8pm. That schedule is built to keep the game moving quickly: the celebrities meet for the first time, then head straight into a first mission.
Claudia Winkleman in the Scottish Highlands
Winkleman hosts from the Scottish Highlands, with a cast that includes Amol Rajan, Bella Ramsey, James Acaster, James Blunt, Jerry Hall, Joanne McNally, Joe Lycett, Julie Hesmondhalgh, King Kenny, Leigh-Anne Pinnock, Maya Jama, Michael Sheen, Miranda Hart, Myha’la, Professor Hannah Fry, Richard E Grant, Rob Beckett, Romesh Ranganathan, Ross Kemp, Sebastian Croft and Sharon Rooney. That lineup gives the new run breadth across comedy, music, drama and presenting, which is exactly the sort of mix this format depends on when the game turns on trust rather than expertise.
Traitor or Faithful? Claudia Decides
A one-off bonus show, Traitor or Faithful? Claudia Decides, will explain how Winkleman chooses her Traitors. It lands on iPlayer from 9:15pm on 1 October, which adds a second layer to the launch night and gives the audience a look at the decision process before the season settles into its Thursday-and-Friday rhythm.
The extra material is not just padding around the main series. The first season’s finale peak of 15.4m was the highest rating episode to an entertainment programme since 2016, so this return has a benchmark that is unusually hard to match. One is leaning into that by pairing the new opening episode with the bonus show and a steady twice-weekly schedule rather than stretching the rollout thin.
Uncloaked with Ed Gamble
Ed Gamble will again host Uncloaked, where banished and murdered players join previous celebrity and non celebrity-players for a debrief and reactions. That gives the franchise a built-in post-episode outlet: the main show supplies the gameplay, and the follow-up turns the exits and betrayals into a second piece of programming rather than a dead end.
For viewers, the practical takeaway is simple: the new season starts at 8pm on 1 October, the bonus episode arrives at 9:15pm the same night on iPlayer, and the rest of the run follows on Thursday and Friday evenings at 8pm. The return is being scheduled like a property the expects to hold attention, not merely repeat it.
