Season 6 Announcement and Release Details
Apple TV+ announced that the sixth season of “Slow Horses” will premiere on 16 September 2026. Six episodes will drop weekly on Wednesdays, ending on 21 October 2026. The season adapts Mick Herron’s novels *Joe Country* and *Slough House*, and follows MI5 director Diana Taverner as she draws the Slough House team into a “fatally high-stakes game of retaliation and revenge,” forcing them to go on the run.
Series Background and Recent Accolades
The series debuted in 2022, based on Herron’s Slough House novels, and quickly became a leading Apple TV+ title. It has earned BAFTA and Emmy nominations, winning several awards, and all five seasons hold a “Certified Fresh” rating on Rotten Tomatoes, reinforcing its critical standing.
Cast, Crew, and Showrunner Transition
Returning cast includes Gary Oldman (Jackson Lamb), Jack Lowden (River Cartwright), Kristin Scott Thomas (Diana Taverner), Christopher Chung (Roddy Ho), Saskia Reeves, Aimee-Ffion Edwards, Rosalind Eleazar, Jonathan Pryce, and Hugo Weaving. Lenny Rush joins as a new character. See-Saw Films continues production, with Gaby Chiappe now showrunner, succeeding Will Smith, and Adam Randall returning as director.
Official Statements from Apple and Production
Apple’s announcement confirmed the September launch, weekly cadence, and adaptation of Herron’s two novels. The service also noted that “Slow Horses” is renewed for a seventh season based on *Bad Actors*, and that an eighth season is reportedly in development. Gaby Chiappe is credited with leading the series while maintaining its blend of espionage and dark comedy.
Critical Reception and Concerns Over Creative Shift
Observers note the showrunner change could affect tone. Christopher Chung said each season “has a slightly different flavour, so I don’t think the fans will be disappointed,” suggesting confidence despite potential shifts.
Conflicting Reports on Future Seasons
9to5Mac says an eighth season is in production, while Radio Times confirms only a seventh season adapting *Bad Actors*, leaving the next novel *Clown Town* unadapted. The reports differ on the series’ longer-term plan.

- “Roddy may or may not have learned a little bit from his past transgressions in season five, so he might be a little bit more holistic and spiritual about things going forward, having learned from what happened with him and his girlfriend.” — Christopher Chung, Actor (Roddy Ho)
- “fatally high-stakes game of retaliation and revenge” — Variety, Entertainment Publication
What’s Next for the Franchise
