The Traitors Season 4 Release Schedule
The Traitors season 4 in the UK kicks off on Thursday 1 January 2026 at 8 pm on BBC One, with new episodes dropping across that first Thursday–Saturday block. It is one of those New Year’s launches that quietly takes over the whole week – the kind where the tree is still up, but everyone is already arguing about who looks suspicious at the round table.
For the first few nights, the BBC is going heavy on the rollout:
-
Episode 1 – Thu 1 January 2026, 8 pm, BBC One
-
Episode 2 – Fri 2 January 2026, 8 pm, BBC One
-
Episode 3 – Sat 3 January 2026, 7:45 pm, BBC One
-
Episode 4 - Wednesday 7th January at 8 pm
-
Episode 5 - Thursday 8th January at 8 pm
-
Episode 6 - Friday 9th January at 8 pm
-
Episode 7 - Wednesday 14th January at TBC
-
Episode 8 - Thursday 15th January at TBC
-
Episode 9 - Friday 16th January at TBC
-
Episode 10 - Wednesday 21st January at TBC
-
Episode 11 - Thursday 22nd January at TBC
-
Episode 12 - Friday 23rd January at TBC
After that opening burst, season 4 is expected to settle into its usual pattern of airing three nights a week, typically Wednesday to Friday, across a 12‑episode run. It fits that classic winter routine in the UK: cold evenings, hot drinks, and a group of strangers trying very hard not to look guilty under candlelight.
The Traitors Season 4 Cast
The Traitors UK season 4 cast features 22 new civilian players from across the UK, once again overseen by Claudia Winkleman. The BBC has kept the exact line‑up under tighter wraps this time, but the mix follows the familiar pattern: different ages, jobs, and regions, all thrown into the same Scottish castle with up to £120,000 at stake.
Confirmed and returning key faces behind the show include:
-
Claudia Winkleman – Host, back with the fringe, the knitwear, and the unnervingly calm stare.
-
22 UK contestants – Everyday players (teachers, office workers, creatives, frontline staff, and more) chosen from across England, Scotland, Wales, and Northern Ireland.
-
Production once again uses Ardross Castle in the Scottish Highlands, which has basically become a character in its own right at this point.
Fans often say the real fun starts a few episodes in, once names and accents become familiar and the first “did not expect that person to be a Traitor” moment hits. Season 4 is set up to lean even harder into that psychology and paranoia.
Traitors Season 4 Release Time
The Traitors season 4 will air in the UK at 8 pm on BBC One for the entire run, with a slightly earlier 7:45 pm start for episode 3 on the Saturday. That earlier 8 pm slot is a shift from the show’s more traditional 9 pm window, and it makes the series feel a bit more like “family‑room appointment TV” than strictly late‑night obsession.
For the first week in the UK:
-
Thu 1 Jan – 8 pm (Ep 1)
-
Fri 2 Jan – 8 pm (Ep 2)
-
Sat 3 Jan – 7:45 pm (Ep 3)
Episodes are usually close to an hour, and many viewers now build small rituals around them – quick dinner, no phones, and then a half hour afterwards to debate whether a particular side‑eye at the round table “means something” or was just someone tired of the cloak.
Where to Watch The Traitors Season 4?
In the UK, The Traitors season 4 will air on BBC One and stream on BBC iPlayer, with each episode added to iPlayer shortly after broadcast. Seasons 1–3 are already available on BBC iPlayer, so anyone late to the party can catch up before New Year’s Day or even binge during the gap between Christmas leftovers and the first round table.
For UK viewers, the setup is simple:
-
Live broadcast on BBC One at the scheduled times.
-
On‑demand streaming via BBC iPlayer (TV, mobile, tablets, consoles), with a BBC account and UK TV licence.
Fans who like more than just the main episodes also get The Traitors: Uncloaked, the official companion show featuring host Ed Gamble and guests, airing on BBC Two/BBC One and streaming on iPlayer and BBC Sounds after the main episode. It has turned into the space where over‑analysers, theory‑makers, and “that one mate who always spots the Traitor first” feel completely at home.
