The Traitors 2027 Start Date: Series 5 Is Due on BBC One, Date Not Yet Set

The Traitors series 5 is coming to BBC One and BBC iPlayer in 2027, though the British Broadcasting Corporation (BBC) has not set a start date as of 6 November 2026, according to the trade titles Advanced Television and Televisual. The BBC’s own pages were not reachable for this report, so every fact below is drawn from at least two independent newsrooms, named in the text.

If you are looking only for the exact date, there is not one yet: the two trades say “2027” and nothing narrower. This page sets out what the BBC has confirmed, the renewal schedule that runs to 2030, and when last year’s series started and ended, and it will be updated when a date is announced.

What the BBC has confirmed about The Traitors series 5

Advanced Television and Televisual both reported in March 2026 that “The Traitors series five is coming to BBC One and iPlayer in 2027.” Neither a month nor a day has been published.

Series 5 timing	2027 (year only)
Start date	Not yet announced
Channel	BBC One and BBC iPlayer

Countdown sites that name a specific January 2027 date are guessing; no source confirms one, so this page does not print it.

The Traitors renewal timeline: series 5 to 8 and Celebrity series 3 to 5

Advanced Television, Televisual and the Royal Television Society (RTS) all reported a three-year deal that keeps the main show and The Celebrity Traitors on BBC One and BBC iPlayer until at least 2030. The trades set out the series by year.

Year	Main series	Celebrity series
2027	Series 5	Celebrity series 3
2028	Series 6	Celebrity series 4
2029	Series 7	Celebrity series 5
2030	Series 8	Not listed

The Celebrity Traitors series 2 fell within this run. The Scotsman and Radio X both reported that it “begins on Thursday 1 October 2026 at 8pm on BBC One and BBC iPlayer” and ran 10 episodes.

When The Traitors series 4 started and ended in 2026

For a guide to the timing, last year’s main series is the closest comparison. Hello Rayo and TellyMix both reported that series 4 launched on Thursday 1 January 2026, New Year’s Day, at 8pm, and finished with its final on Friday 23 January 2026.

Milestone	Date (last year)
Launch	Thursday 1 January 2026, 8pm
Final	Friday 23 January 2026
Episodes	12
Run, launch to final	23 days

Counting from launch to final, series 4 ran across 23 days. Whether series 5 keeps the New Year’s Day slot is not confirmed; treat the 2026 pattern as last year’s, not a 2027 schedule. A January 2027 printable calendar is a place to mark a date once the BBC sets one, and a printable yearly calendar covers the whole run.

How to watch The Traitors in the US

Peacock says viewers can “Stream The Traitors, The Traitors: UK, and The Traitors: Australia now on Peacock.” In Britain, BBC One and BBC iPlayer carry the UK series. The series 5 streaming timing in the US follows the BBC’s unannounced 2027 date.
