Apple TV+ has confirmed the release date for the sixth season of its espionage drama Slow Horses, with the premiere scheduled for September 16, 2026. The platform released the official trailer today, outlining a narrative arc that finds the Slough House team forced into hiding as their former colleagues become targets of a systematic threat.
Production and Cast Details
Directed by Adam Randall, the upcoming season retains the core ensemble, including Gary Oldman, Kristin Scott Thomas, and Jack Lowden. The production features the return of Olivia Cooke, reprising her role as Sid, and introduces Lenny Rush to the cast. The season consists of a weekly release schedule, beginning with the premiere on September 16 and concluding with the final episode on October 21.
Operational Timeline
The release strategy maintains the series' traditional rollout, with new episodes arriving on the streaming service every Wednesday. This six-week run covers the entirety of the season’s narrative, transitioning the Slough House agents from their typical administrative exile into active, high-stakes evasion. The shift in plot focus reflects a departure from the series' previous procedural structure, placing the characters in a direct survival scenario.
The arrival of the sixth season on September 16 solidifies the show's position in the Apple TV+ autumn lineup. By concluding on October 21, the series avoids competing with year-end prestige programming, ensuring the narrative arc completes its run within a distinct five-week window.
