Ahead of season five which is set to premiere on September 24th, 2025, Apple TV Plus has announced that Slow Horses will be returning for a six-episode seventh season that will be based on Mick Herron’s Bad Actors — the eighth novel in their Slough House series.

The tech giant’s streaming service has renewed Slow Horses for a seventh season — even though the Gary Oldman-led spy drama’s fifth installment won’t premiere for another couple of months. The pickup follows a season six renewal in October 2024, which came shortly after season four concluded.

"Slow Horses" season 7 is officially a go. No, that's not a typo. While "Slow Horses" season 5 is still a few months away from its Sept. 24 premiere and season 4 is still campaigning for Emmy nominations, season 7 is now ramping up production.
