‘Slow Horses’ Season 6 Release Date, Time and Where to Watch as Slough House Returns

Fans of Apple’s quirky spy drama can finally mark their calendars. ‘Slow Horses’ season six is set to premiere globally on Wednesday, September 16, 2026, with the first episode available and a new episode released weekly until October 21. This means the dysfunctional agents of Slough House are just days away from another chaotic adventure, and this time, the stakes are personal.

The premiere comes after months of eager anticipation for a series that has quietly emerged as one of Apple’s biggest successes. Gary Oldman will reprise his role as Jackson Lamb for the sixth season, and the early hints suggest that the entire team, rather than just one unfortunate agent, is being drawn into a perilous situation.

The rollout will follow the same pattern established since the show’s inception. The complete episode schedule kicks off on Wednesday, September 16 for episode one, followed by episodes on September 23, September 30, October 7, and October 14, with the finale airing on October 21. There will be no binge release for this season.

This weekly release schedule has become a hallmark of the show. Apple TV has confirmed that the six-episode season will be released weekly on Wednesdays through October 21, adhering to the model that has been in place since the show debuted, rather than opting for a binge format.

While six weeks might feel like a long wait between episodes for a show known for its cliffhangers, loyal viewers are accustomed to this pacing. The format has never hindered the show’s momentum, and there’s no reason to believe it will start now.

If you’re eager to know the exact time of the season premiere, you might need to manage your expectations. Apple has yet to announce an official release time for the new season, and viewers should be wary of unofficial reports regarding a specific hour until Apple provides confirmation.

The best approach is to check the app on the day of the premiere. It’s advisable to look at the app on the morning of September 16 in your local time zone.

Apple typically remains tight-lipped about precise release times across its offerings, so this lack of information is not unusual. Patience is key in this case.

As for where to watch ‘Slow Horses’ season six, the answer is straightforward. The series remains exclusive to Apple TV, and there are no indications that season six will be available elsewhere. Viewers hoping to catch it on a competing streaming service or through a free trial will likely be disappointed.

To watch the new season, you will need an active subscription. Those wanting to enjoy the new episodes along with all five previous seasons will require an Apple TV subscription. The entire back catalog is available for anyone looking to catch up or rewatch before the new episodes begin.

Given Apple’s strict control over this series, it’s unlikely that this pattern will change anytime soon. If you’re new to the show, now is the perfect time to binge the earlier seasons before the new episodes start airing weekly.

The premise of the new season suggests a departure from the usual formula. This season follows the Slow Horses as they navigate a high-stakes game of retaliation and revenge orchestrated by Diana Taverner. This setup places every member of Slough House in jeopardy, rather than isolating a single agent.

Season six will adapt fresh source material, drawing from ‘Joe Country’ and ‘Slough House’, the sixth and seventh novels in Mick Herron’s Slough House book series.

One of the most exciting aspects for longtime fans is the return of a character many believed was gone for good. Olivia Cooke is back as Sid Baker, a character who was shot in the head during the first season, and the trailer concludes with her surprising River. Lamb himself even humorously notes that spies often fake their own deaths.

Newcomer Lenny Rush also joins the cast this season. Rush, who won a BAFTA for the BBC’s ‘Am I Being Unreasonable?’, has a role that remains under wraps, though images show him alongside Christopher Chung’s Roddy Ho. With a plot centered around revenge and a presumed-dead character returning, season six is poised to be one of the most unpredictable yet.

With Sid Baker’s shocking comeback and a season focused on revenge, how do you think Slough House will navigate this tumultuous round, and are you as surprised by River finally confronting her again as the rest of us?
