The sixth instalment of the MI5-rejects saga arrives on Apple TV on Wednesday, September 16, 2026. Titled “Circle of Life,” the opening episode sets a grim tone: a shadowy duo is eliminating anyone linked to Slough House, erasing records and cutting off paychecks. The series now runs six episodes, each releasing weekly on Wednesdays, with the finale slated for October 21. This compressed schedule forces the show to compress two of Mick Herron’s novels—Joe Country and Slough House—into a single season, a challenge that will test its narrative agility.
New creative direction under Gaby Chiappe
Long-time head writer Will Smith departed after Season 5, handing the reins to co-executive producer Gaby Chiappe. While Smith’s background in political satire (think The Thick of It and Veep) gave the series its sharp edge, Chiappe brings a different flavor, focusing on suspense and character-driven intrigue. The opening scene juxtaposes Jackson Lamb’s (Gary Oldman) boozy defiance—he strolls into the Italian eatery below Slough House with a bottle of red—as a solemn moment shows River Cartwright (Jack Lowden) mourning his late grandfather, a railway-obsessed spy. This contrast underscores the show’s ability to blend dark comedy with genuine pathos, even as some critics note a slight “try-hard” effort to prove it still knows its own tone.
Cast, characters and the expanding mystery
The core ensemble returns unchanged: Gary Oldman as the gremlin-like director-of-chaos Jackson Lamb, Kristin Scott Thomas as the newly crowned First Chair Diana Taverner, and Jack Lowden as the earnest yet increasingly haunted River Cartwright. New antagonists appear in the form of Kyle Soller and MyAnna Buring, portraying a lethal pair responsible for the assassinations. Their presence deepens the season-long puzzle: why are Slough House agents being hunted, and who is pulling the strings behind the erasures in Park’s systems? Subplots hint at connections to a Russian finance bot-farm, a mysterious political donor Peter Judd (Samuel West), and River’s own family legacy, notably his father Frank Harkness (Hugo Weaving). Each thread is presented as a clue, promising the series’ trademark twist-heavy payoff.
How to watch and where to find the best deal
To stream Season 6, viewers need an active Apple TV subscription, now priced at $15 per month after a $2 increase. The service is also part of the broader Apple One bundle, which adds Apple Music, Arcade and iCloud for $22 per month. For the price-conscious, a joint Apple TV + Peacock package is available at $15 monthly, while Comcast Xfinity customers can opt for a StreamSaver bundle that includes Netflix and Peacock alongside Apple TV. New subscribers can take advantage of a 7-day free trial, allowing a risk-free look at the first episode before committing.
International travelers who wish to keep up with the series can use a VPN to mask their location and avoid regional restrictions. A VPN encrypts traffic, safeguards public-Wi-Fi connections, and may circumvent throttling, though users should verify each streaming platform’s policy on VPN usage to stay compliant with terms of service.
Episode release schedule
Apple TV follows its usual weekly rollout: Circle of Life (Sept 16), Daddy Issues (Sept 23), Resurrection (Sept 30), Lost & Found (Oct 7), Sayonara (Oct 14) and the finale Judgment Day (Oct 21). Episodes typically become available around 9 p.m. ET on Tuesday evenings, giving East-coast viewers a chance to start watching slightly ahead of the official Wednesday release.
With the season already renewed for a seventh and eighth instalment—Season 7 wrapped filming in 2025 and Season 8 was announced just before the premiere—fans can rest assured that the misfit squad at Slough House will continue to bumble, fight, and somehow survive the endless bureaucratic mazes that define their world.
