Club Benefits
“The Traitors” U.K. is quite a unicorn in the modern television landscape. In an era where appointment TV has all but died out in favor of on-demand streaming, it’s a rare watercooler series that appeals across generations and has millions of viewers tuning in multiple times a week at a specific time to ensure they don’t miss an episode before seeing spoilers on social media.
Across its three complete seasons (and celebrity special) to date, there isn’t a bad one in the bunch. “The Traitors” U.K.'s quality is remarkably consistent, and the currently airing season 4 is already shaping up to be a real doozy, with one of the most explosive confrontations in the show’s entire history. However, because it’s not finished, I’m excluding it from this ranking.
You can pick any season of “The Traitors” U.K. to watch right now, and you’re going to be getting some true reality TV gold. But if you want to start with the best of the best, or just compare your favorite (and least favorite) seasons to mine, here’s my ranking of every season of “The Traitors” U.K. so far.
Every season of 'The Traitors' U.K. ranked
4. Season 3
As noted, there are no bad seasons of “Traitors” U.K., but if I had to pick the weakest, it would definitely be the third. It came hot on the heels of two stellar seasons that really solidified the show as a favorite of the British public (and international viewers alike), and never quite managed to live up to the twists and turns of the murder games that came before it.
Its biggest issues were two-fold. Firstly, the lack of truly excellent traitors meant that there was less satisfying scheming than usual, and the “Seer” twist at the end robbed viewers of what could have been an unpredictable finale. Secondly, this season feels a little more mean-spirited than the rest, with some contestants taking what is ultimately just a game show quite personally. This led to roundtables that were more hostile than enjoyable.
3. Celebrity Season
I had reservations about “The Celebrity Traitors” before it debuted in October 2025, but my pre-broadcast fears proved to be almost entirely unfounded. I worried it might be your typical celebrity spinoff, which sees fading “stars” desperately seek to boost their social clout above all, but smart casting from the producers, and a laidback vibe overall made for great entertainment.
Alan Carr proved to be the unexpected hero of the celebrity season, and a much more cunning traitor than any of the public watching at home likely expected. Because the celebrities were playing to win money for their chosen charity, rather than to win a share of the cash pool for themselves, the contests also took proceedings very much in the parlor game spirit they were intended. This was the tonic that was needed after the more hostile season 3.
2. Season 1
“The Traitors” U.K. was a phenomenon right out of the gate. The reality show needed no time at all to find its footing, and in its freshman run delivered a season that remains just as utterly compelling in 2026 as it was more than three years ago when it broadcast. It’s the simplest season, without the future “twists” added to spice up the format in later seasons, but that’s arguably a strength; the focus is very much on rooting out traitors above all else.
Season 1 also has my favorite traitor to date, Wilfred “Wilf” Webster, who goes on quite the journey. While some of season 1’s novelty has been lost now that “The Traitors” core concept doesn’t feel so fresh, it’s still packed with iconic moments. Tom Elderfield declaring to a stunned breakfast room table that fellow consistent Alex Gray can’t be a traitor because “she’s my girlfriend” is a moment of sheer hilarious madness that lives rent-free in my head.
1. Season 2
When it comes to the best of the best, I think of “The Traitors” U.K. season 2. These 12 episodes pack in so many twists and turns that you’ll probably binge-watch the entire thing in just a couple of days. To explain the primary reason I rate this season so highly would be a huge spoiler, so I’ll just note that it’s a highly unpredictable season in the best way possible.
Whether it be Paul Gorton’s early-season arrogance, believing his own hype when it’s suggested he’s viewed as the most popular contestant in the castle, or faithfuls Zack Davies and Jaz Singh proving to be some of the best faithfuls at sniffing out traitors in the show’s history, there’s so many high points in season 2 that just talking about it makes me want to start a rewatch now.
