‘Slow Horses’ Season 6 Episode 1 Release Date, Time, Preview, And Where To Watch
Apple TV’s acclaimed spy drama is finally back, and the timing could not be more fitting for fans who have spent the year wondering how Jackson Lamb’s misfit team would return to the field. ‘Slow Horses’ will premiere its sixth season globally on Wednesday, September 16, 2026, with the first episode arriving and one new episode following weekly until October 21. The countdown that fans have tracked since the previous finale is officially over.
The new season will run six episodes total, released every Wednesday until the finale. With the premiere here, viewers can finally see how the Slough House team handles a story that promises to hit closer to home than any previous run of ‘Slow Horses’.
Slow Horses Season 6 Release Date And Episode Schedule
The sixth season is adapted from ‘Joe Country’ and ‘Slough House,’ the sixth and seventh novels in Mick Herron’s Slough House book series. The full episode schedule runs Wednesday, September 16 for episode one, then September 23, September 30, October 7 and October 14, with the finale landing October 21.
This mirrors the release pattern the show has followed since it began, with Apple TV opting for a weekly drop rather than releasing the whole season at once. Apple has not released episode titles or runtimes for the new season, though the streamer has already ordered a seventh season of the show.
Reported runtimes for the season range from 46 to 50 minutes for the first five episodes, rising to a full hour for the season finale. There is some minor disagreement over episode two’s exact length, with one database listing it at 46 minutes rather than 47, though an Australian Classification Board entry offers some support for the longer figure.
Apple has not released a full episode by episode plot summary, so confirmed story details beyond the season’s overall premise remain limited. That has left outlets and fans piecing together expectations mostly from trailers and first look images rather than a detailed rundown of what happens episode to episode.
Slow Horses Season 6 Episode 1 Release Time
Apple has not announced an official release time for the new season, and viewers should be cautious of unofficial reports claiming a specific hour until Apple confirms one. The safest approach is simply checking the app the morning of September 16 in whatever local time zone a viewer happens to be in.
Because Apple TV releases its originals globally, a Tuesday evening United States launch would translate to roughly 2 a.m. British Summer Time in the United Kingdom and 3 a.m. Central European Summer Time across much of Europe on Wednesday. Later episodes are likely to follow the same pattern, though Apple could still change its release cadence as the season progresses.
Given how consistently Apple TV has handled the rollout for ‘Slow Horses’ across five previous seasons, there is little reason to expect a dramatic shift in approach now. Viewers who have followed the show since its 2022 debut will likely recognize the familiar rhythm of checking the app first thing in the morning rather than waiting for a specific advertised hour.
Where To Watch Slow Horses Season 6
There is no ambiguity about where to find the new season. ‘Slow Horses’ remains exclusive to Apple TV, and there is no indication that season six will simulcast anywhere else. Anyone wanting to dive in will need an active subscription, and viewers hoping to catch it on a rival streamer or through a free preview window will be disappointed.
Viewers who want to catch the new season, along with all five previous seasons, will need an active Apple TV subscription, and the full back catalog remains available for anyone who wants to catch up or rewatch before the premiere. For newcomers, that means there is still a window to binge through the earlier seasons before the new episodes begin arriving weekly.
Slow Horses Season 6 Cast And Preview
Gary Oldman returns as Jackson Lamb, joined by Jack Lowden, Kristin Scott Thomas, Saskia Reeves, Christopher Chung, Aimee-Ffion Edwards, Rosalind Eleazar, and Jonathan Pryce. Hugo Weaving is also back as Frank Harkness, while ‘House of the Dragon’ star Olivia Cooke reprises her role as Sidonie “Sid” Baker for the first time since ‘Slow Horses’ Season 1. The season also introduces BAFTA winner Lenny Rush, though his role has been kept under wraps.
Gaby Chiappe adapted the season for television, with Adam Randall returning to direct. Apple TV has described the new story as putting the team on the run after Diana Taverner, played by Kristin Scott Thomas, brings them into a fatally high stakes game of retaliation and revenge.
That premise marks a genuine departure from the show’s usual format, since ‘Slow Horses’ has traditionally introduced a brand new case each season for the Slough House team to unravel. Looking ahead, season 6 will be followed by season 7, which Apple TV has already confirmed will be based on Mick Herron’s novel ‘Bad Actors.’
With Sid Baker’s return, Louisa Guy pulled back into the fold, and the entire team apparently being hunted rather than just one unlucky agent, this season looks positioned to test the Slough House crew in ways the earlier seasons never quite did. Which returning face are you most curious to see back in the field, and how do you think Lamb’s team survives being targeted all at once?
