Silent Witness has not had an officially confirmed BBC start date for 2026 yet, but the best current indication is that the new run is likely to begin in early 2026, probably around late January or early February.

Quick Scoop

  • BBC One has confirmed that Silent Witness will return for series 29 in 2026, marking the show’s 30th anniversary year.
  • The series traditionally starts in early January , with season 27 launching in the first week of January 2024 and season 28 starting on Monday 6 January 2025 at 9pm.
  • A 2026 preview noted that, although the new series is “incoming”, the BBC had “no update” on the exact start date and it was missing from the early winter schedules.

Likely 2026 Start Window

  • Commentators and TV guides suggest season 29 will “likely” begin in January 2026 , following the usual pattern, but stress this is still speculative rather than confirmed.
  • One detailed guide points out that Monday nights remain the usual Silent Witness slot and speculates that, once the current Inspector Lynley run ends on Monday 26 January 2026, Silent Witness could feasibly return on Monday 2 February 2026.

What’s Confirmed vs Speculation

  • Confirmed :
    • Series 29 is happening and will air on BBC One in 2026.
* Filming for the 2026 run began in Birmingham around March 31, 2025, indicating the season is well into production.
  • Not yet confirmed :
    • The exact premiere date or BBC listing for the first 2026 episode.

How to Stay Updated

  • Keep an eye on:
    • BBC One’s drama schedules and the BBC iPlayer “Coming Soon” area as January rolls on.
    • Major TV guides such as Radio Times and TV & streaming news sites, which are already tracking season 29 updates.

At this point, the accurate answer to “when does Silent Witness start 2026?” is: sometime in early 2026, very likely late January or early February, but with no official BBC air date announced yet.
