Gary Oldman is back as the grumpy spy boss Jackson Lamb, and this time his team of MI5 rejects is running for their lives. Slow Horses Season 6 premieres on Apple TV on Wednesday, September 16, 2026, and the streaming service is releasing one episode per week. The season has six episodes in total, with the finale arriving on October 21, 2026.
The new season adapts two books from Mick Herron’s Slough House series: Joe Country and Slough House. It is the first time the show has combined two novels into a single season. Olivia Cooke also returns as Sid Baker, the agent who was shot in Season 1 and presumed dead.
Every Slow Horses Season 6 Episode Date
Apple TV is following its usual pattern of weekly releases. New episodes drop every Wednesday for six straight weeks. Here is the full schedule:
- Episode 1: Circle of Life — September 16, 2026
- Episode 2: Daddy Issues — September 23, 2026
- Episode 3: Resurrection — September 30, 2026
- Episode 4: Lost and Found — October 7, 2026

The finale is the longest episode of the season at roughly 60 minutes. Most other episodes run between 47 and 50 minutes.
Release Time in Different Countries
Apple TV has not announced an exact release time, which is normal for the platform. New episodes typically become available in the early morning hours of the release day, local time. Viewers in the United States, United Kingdom, Canada, and Australia usually see new episodes appear between midnight and 3:00 AM ET. Fans in India and the UAE can expect episodes to go live later the same day. The safest approach is to check the Apple TV app on the morning of September 16 and each following Wednesday.
The show streams globally on Apple TV, so viewers in Germany, France, and other countries get the episodes on the same day as the US and UK.
What Happens in Season 6
The official synopsis is short but tense: the Slow Horses are on the run as Diana Taverner (played by Kristin Scott Thomas) pulls them into a dangerous game of revenge. Someone is hunting down people connected to Slough House, and Lamb’s team has to disappear before they become the next targets.
The trailer shows Lamb asking Taverner a blunt question:
“Have you any idea why my Slow Horses keep turning up dead?”
The footage includes shootouts, car chases, and a kill list with the names of Slough House agents on it. Gary Oldman has said the season is darker and heavier than earlier ones, with the team dealing with the fallout from a plot to destabilize the country.
A new pair of assassins is played by Kyle Soller and MyAnna Buring. Hugo Weaving returns as Frank Harkness. Lenny Rush also joins the cast in a new role.
Cast: Who Is Coming Back
The full ensemble cast is returning for Season 6. Gary Oldman leads as Jackson Lamb. Jack Lowden is back as River Cartwright. Kristin Scott Thomas returns as Diana Taverner. Other returning names include:
- Saskia Reeves as Catherine Standish
- Christopher Chung as Roddy Ho
- Rosalind Eleazar as Louisa Guy
- Aimee-Ffion Edwards as Shirley Dander
- Joanna Scanlan as Moira Tregorian
- Samuel West as Peter Judd
- Ruth Bradley as Emma Flyte
- Tom Brooke as J.K. Coe
- Jonathan Pryce as David Cartwright
- Hugo Weaving as Frank Harkness
The biggest return is Olivia Cooke as Sid Baker. She was last seen in Season 1 when she was shot and apparently killed. River later found that her records had been erased, leaving her fate unclear. The Season 6 trailer confirms she is alive and waiting for River at the top of a staircase. “Hello River,” she says with a smirk. It is one of the season’s biggest surprises.

All five previous seasons of Slow Horses are streaming on Apple TV. Anyone who wants to catch up before September 16 can watch them now. The show has been praised by critics, with two seasons holding a perfect 100 percent score on Rotten Tomatoes.

Apple has already renewed the show for Season 7. That season will adapt Mick Herron’s novel Bad Actors, the eighth book in the series. Gary Oldman has confirmed he will return. The show’s creative team has stayed largely the same, with Gaby Chiappe adapting Season 6 for television and Adam Randall directing.
