When will Celebrity Traitors 2026 series 2 air on BBC?

While the BBC has not yet confirmed an exact launch date, the 10-episode second series is scheduled to air in Autumn 2026.

The show’s debut celebrity series kicked off on Wednesday, 8 October 2025, running twice weekly across October and November.

If the BBC sticks to that formula, fans can expect the 10-episode second series to land in early October 2026, likely occupying its prime-time Wednesday and Thursday night slots – though again, nothing has been confirmed.

Filming at Ardross Castle wrapped earlier this summer, with BBC content bosses teasing plenty of tears, shock backstabs, and high drama.

An official launch date announcement from the BBC is expected within weeks.

Ed Gamble will also return with companion show Celebrity Traitors: Uncloaked, airing on immediately after each episode.
