Here’s what’s known about the next season of Slow Horses as of now.
- Official renewals: Apple TV+ extended Slow Horses for additional seasons beyond the fifth. Reports from major outlets indicate renewals for seasons 6 (and even 7) were announced in 2024–2025, with production moving forward after season 5 aired. This suggests the show is intended to continue beyond season 5, though exact dates were not yet fixed at the time of those announcements.
- Expected timing: Based on typical production patterns for Slow Horses—where seasons often premiered in the fall and filming for consecutive seasons has occurred—most industry reporting places Season 6 in late 2025 to 2026 window, with fall 2026 being a common target for premieres if schedules hold. However, there isn’t a formal, publisher-confirmed date yet.
- What to expect content-wise: Season 6 is anticipated to continue the mix of espionage thriller and dry humor, with returning core cast and new storylines aligned to Mick Herron’s later novels (as adapted for the screen). Cast details have been reported to include Gary Oldman’s Jackson Lamb and other regulars, with additions tied to the Season 6 storyline.
