The Celebrity Traitors (the UK celebrity spin-off of The Traitors) was filmed in spring 2025, with principal shooting running from 22 April 2025 through May 2025 at Ardross Castle in the Scottish Highlands.

Quick Scoop: Key Filming Dates

  • Filming for The Celebrity Traitors began on 22 April 2025 and wrapped the following month, covering the full nine-episode run.
  • Press coverage and production notes describe it broadly as being filmed in spring/early summer 2025, in line with the regular Traitors filming window.
  • The show then aired later in the year, with its BBC One run starting in October 2025 in the UK schedule.

Location And Timing Vibes

  • The series was shot at Ardross Castle in the Scottish Highlands, the now-iconic Traitors castle used for the civilian series as well.
  • Season 4 of the civilian Traitors and The Celebrity Traitors were filmed back‑to‑back in summer 2025, which matches the late-spring/early‑summer production window mentioned for the celeb edition.
  • Viewers see moody cloaks and log fires, but reports note that it is actually filmed in the warmer months rather than winter, despite the gothic atmosphere on screen.

Why The Timing Matters For Fans

  • Spring 2025 filming explains why fans and tabloid watchers noticed several participating celebrities disappearing from their usual shows and radio gigs around April.
  • The gap between filming (April–May 2025) and broadcast (October–early November 2025) allowed the BBC to cut the episodes, build hype, and slot it into an autumn “event TV” schedule.

TL;DR: If you’re asking “when was The Celebrity Traitors filmed,” the answer is: it was shot at Ardross Castle in the Scottish Highlands from 22 April 2025 through May 2025, during spring/early summer 2025, then aired in autumn 2025.
