Direct answer: Slow Horses has been renewed for both a sixth and a seventh season, with Season 6 scheduled to premiere after Season 5, and Season 7 already confirmed. Based on recent announcements, fans can expect at least two more seasons beyond Season 5, with Season 6 likely arriving in 2026 and Season 7 following thereafter. Details and context:
- Renewal status: Apple TV+ officially announced Season 6 in October 2024 and subsequently confirmed Season 7 in July 2025, making Slow Horses one of Apple TV+'s longest-running series to date.
- Season count: As of these announcements, the series will continue through Season 6 and Season 7, expanding beyond the current fifth season.
- Expected timelines: Season 5 premiered in 2025, with Season 6 already filmed and anticipated to follow in 2026, while Season 7 is planned after that. Exact dates can shift, but the pattern has been a roughly annual-to-biennial release cadence for newer seasons.
