Celebrity Traitors becomes most-watched UK show of 2026

The launch of Celebrity Traitors series 2 has become the most-watched television programme in the UK so far in 2026, with over 15 million people tuning in within seven days of its broadcast ^[1]. According to data from ratings organisation Barb, an average of 15.41 million UK viewers watched the first episode across all platforms, including TV, computers, tablets, and smartphones ^[2]. This marks the highest seven-day consolidated audience ever recorded for The Traitors, whether in its celebrity or public format.

The figure surpasses the 14.93 million viewers who watched the BBC’s broadcast of England’s World Cup semi-final loss to Argentina on July 15 ^[2]. The previous record was held by the finale of the 2025 Celebrity Traitors series, which drew 14.94 million viewers over seven days ^[1]. Episode two also performed strongly, securing 14.95 million consolidated viewers.

The series, hosted by Claudia Winkleman, began on October 1 on the BBC, with actor Richard E Grant immediately announcing himself as a traitor—shocking the other contestants ^[1]. His bold move set the tone for the drama-filled season. Rob Beckett, a previous winner, noted that comedians often thrive in such settings due to their ability to shift emotions and control the room through humour.

While 28-day ratings are not yet available, historical data shows that the standard series of The Traitors saw a rise from 11.85 million at seven days to 13.29 million by 28 days, suggesting the Celebrity Traitors numbers could grow further ^[2]. The public version of the show has not yet matched the celebrity series’ viewership, with its highest seven-day total reaching 11.99 million.

The phenomenon highlights a growing appetite for reality TV with high-stakes social dynamics and celebrity drama, outperforming even major sporting events in audience numbers this year ^[1]. The story was first reported by Mirror and The Independent.
