Watch Silent Witness S29 online: Feb 2, 9pm & 7am drop

If you want to watch Silent Witness season 29 online without missing the start, the key detail is timing. The new run begins on Monday, 2 February 2026, with a traditional BBC One broadcast at 9pm, but there’s also an on-demand-first angle via iPlayer that can put you ahead of the TV schedule.

Episode 1 is titled “The Disappearance of Alice Hill” (Part One), and the BBC lists it as a 58-minute episode, airing at 21:00 on the day. You can see those specifics on the BBC’s Episode 1 page.

When is Silent Witness series 29 on (BBC One + iPlayer times)?

Here’s the practical schedule for launch week, because this is where people get caught out.

• Episode 1 (Part One): Monday 2 Feb 2026, 9pm on BBC One (58 minutes).
• Episode 2 (Part Two): Tuesday 3 Feb, following the early-week cadence.

Radio Times reports Episode 1 lands on BBC One at 9pm and is also on iPlayer, with Episode 2 following the next day. That’s the broadcast rhythm most fans are used to.

The twist is the iPlayer release window. Edinburgh News said Episodes 1 and 2 were available on iPlayer from 7am on Feb 2 (UK time), which effectively rewards early birds and anyone who prefers watching on-demand before work or school runs.

Why you should care: this changes spoiler dynamics immediately. If you assume “everyone watches at 9pm,” you’re going to get burned by people who watched hours earlier. Group chats, social posts, even headlines, the conversation starts when iPlayer drops, not when BBC One starts.

How to watch Silent Witness season 29 online in the UK (iPlayer guide)

If you’re in the UK, the cleanest way to stream Silent Witness season 29 is through BBC iPlayer. You do not need to guess where it is listed or chase unofficial uploads. Start with the official programme hub, which indicates the show is “On iPlayer” and collects episodes in one place.

Use the Silent Witness programme page on the BBC and you’ll see Series 29 alongside the episode list. For the opener, look for “The Disappearance of Alice Hill,” and note the naming convention: it’s split into Part One and Part Two, so you can easily queue the right follow-up.

Quick, practical tips that save time:

• Search iPlayer for “Silent Witness”, then pick Series 29 from the season selector.
• If you’re trying to avoid spoilers, wait until Part Two is also available so you can watch the full story back-to-back.
• If your household is a mix of “broadcast people” and “streaming people,” agree up front whether you’re following the 7am drop or the 9pm BBC One slot.

For viewers abroad: based on the sources above, the confirmed details are UK-focused. If you’re outside the UK, availability can change by territory and licensing, so treat any random “watch now” claims with suspicion until a distributor or a major listing service confirms Series 29 for your region.

What’s new in season 29 (episodes, stories, setting shift, cast)

Silent Witness is not just doing another run of cases. The show is giving itself a clear refresh in-world. The BBC says Series 29 is five stories told over 10 episodes, and the team has relocated to Birmingham, opening the doors of the “Sir William Bowman Centre of Excellence” for the first time.

BBC Media Centre details the returning core cast: Emilia Fox as Dr Nikki Alexander, David Caves as Jack Hodgson, Maggie Steed as Harriet Maven, and Francesca “Fran” Mills as Kit Brooks. Mills also points out we’ll see Kit more settled and “more confident” in how she works, which is a smart way to keep a long-running procedural feeling like it’s still moving forward.

Episode 1, “The Disappearance of Alice Hill,” is your entry point into that refreshed setup, and it’s clearly positioned as a story you can start either at 7am on iPlayer (if the early drop holds) or at 9pm on BBC One if you’re sticking with appointment viewing.

The takeaway: if you want to watch Silent Witness season 29 online, plan around the drop times, not just the TV guide. Check iPlayer early on Feb 2, or tune in to BBC One at 9pm, and keep the BBC hub bookmarked so you can track Part One/Part Two releases as the 10-episode run rolls on.
