Is there a Slow Horses season 5 release date?

Slow Horses Season 5 premiered on Apple TV+ on September 24, 2025, with all six episodes released weekly on Wednesdays (DIRECTV Insider). The announcement came via Variety on June 3, 2025, confirming a September premiere for the new run (Wikipedia citing Variety). The official trailer dropped on September 3, 2025, teasing “a compromised agent, a destabilized London” (Apple TV YouTube).

Confirmed premiere details

UK viewers got simultaneous access when the global premiere hit Apple TV+ on September 24, 2025 — no regional lag, no separate broadcast window (Rotten Tomatoes). Apple’s own platform page lists the season under the tagline “Destabilize,” reflecting the new storyline (Apple TV). The show streams exclusively on Apple TV+ — no third-party deals have emerged.

Episode schedule

The episode rollout followed a strict weekly cadence: Episode 1 “Bad Dates” opened on September 24, followed by Episode 2 “Incommunicado” on October 1, Episode 3 “Tall Tales” on October 8, Episode 4 “Missiles” on October 15, Episode 5 “Circus” on October 22, and the finale “Scars” on October 29 (TV Guide). This six-episode structure matches the pattern set by previous seasons on the platform.

How many episodes are in Slow Horses 5?

Season 5 contains 6 episodes — a standard run for the series — with each installment following the weekly Wednesday release pattern (DIRECTV Insider). IMDb currently lists partial data for the first three episodes: “Bad Dates,” “Incommunicado,” and “Tall Tales,” with early user ratings suggesting viewers found the opening stretch engaging.

Episode list overview

The episode titles and air dates break down as follows: “Bad Dates” (Sep 24, 2025), “Incommunicado” (Oct 1, 2025), “Tall Tales” (Oct 8, 2025), “Missiles” (Oct 15, 2025), “Circus” (Oct 22, 2025), and “Scars” (Oct 29, 2025) (Rotten Tomatoes). The premiere episode brings a mass shooting in London into the season’s opening plot, tied to a mayoral race subplot.

• Episode 1 “Bad Dates” — Sep 24, 2025
• Episode 2 “Incommunicado” — Oct 1, 2025
• Episode 3 “Tall Tales” — Oct 8, 2025
• Episode 4 “Missiles” — Oct 15, 2025
• Episode 5 “Circus” — Oct 22, 2025
• Episode 6 “Scars” — Oct 29, 2025

Runtime and structure

Episode runtimes vary across the season. Episode 2 runs 47 minutes, Episode 3 comes in at 39 minutes, Episode 5 sits at 44 minutes, and the finale “Scars” extends to 51 minutes (TV Guide). This variance is typical for Slow Horses, where individual episodes often shift pace depending on the plot demands of that installment.

Is Slow Horses season 5 good?

The critical reception for Season 5 has been decidedly mixed. The Guardian’s review called it the show’s “worst outing,” suggesting the new season struggles to match the quality of earlier runs (DIRECTV Insider citing Guardian). Yet audience scores tell a different story: IMDb ratings for the early episodes range from 7.7 to 8.1, indicating viewers found value even as critics grew skeptical.

Critic reviews

Major publications have not rushed to defend Season 5. The Guardian’s assessment landed as particularly harsh, questioning whether even Gary Oldman’s central performance could salvage the narrative direction (DIRECTV Insider). Rotten Tomatoes currently shows no aggregated critic score for the season, which may reflect either sparse review count or ongoing score updates.

Audience scores

IMDb user ratings for the first three episodes clock in at 7.7/10 (“Bad Dates”), 7.9/10 (“Incommunicado”), and 8.1/10 (“Tall Tales”) — respectable scores that suggest the core fanbase found the season worth watching despite the critical jitters. This gap between critic and audience sentiment is notable.

Pros and cons

The implication: Slow Horses Season 5 divided opinion sharply. Critics soured while audiences held steady — a split that suggests longtime fans found enough to enjoy even as newcomers or casual viewers might flag this as the series’ weakest link.

Where can I watch Slow Horses season 5 in the UK?

UK viewers can stream Slow Horses Season 5 exclusively on Apple TV+, mirroring the global release strategy (Apple TV). The service holds exclusive rights to the series — seasons 1 through 4 are also available on the same platform for catch-up viewing.

Streaming platforms

Apple TV+ serves as the sole legitimate streaming home for Slow Horses in the UK. No broadcast TV channel carries the series, and no third-party streaming deals exist as of the current date (Rotten Tomatoes). Viewers with existing Apple TV+ subscriptions can stream immediately; those without need to sign up directly through Apple’s service.

Availability status

The series remains exclusive to Apple TV+. Queries about Netflix or Amazon Prime Video availability consistently hit dead ends — neither platform has acquired rights to the Slow Horses library (Rotten Tomatoes). A VPN won’t change this picture, since the rights structure is platform-exclusive by design.

Is there a 6th season for Slow Horses?

Season 6 of Slow Horses has been confirmed, though details remain sparse (DIRECTV Insider). The show’s trajectory — built on Mick Herron’s ongoing Slough House novels — suggests source material will support at least one more run, but concrete production timelines, casting announcements, or a confirmed premiere window have not yet surfaced in public sources.

Filming status

As of the most recent available information, no official announcement regarding filming start dates for Season 6 has emerged. The gap between Season 5’s October 2025 finale and any future Season 6 premiere would typically span several months, consistent with the series’ production cadence.

Cast and plot news

Gary Oldman’s return as Jackson Lamb seems near-certain given his central role, though no formal casting confirmation has been announced. Plot details for Season 6 remain entirely absent from verified sources — the show’s writers will likely draw from Herron’s later novels in the series to craft the new narrative arc.

Summary

Slow Horses Season 5 delivered on its core promise — six new episodes of British spy intrigue, anchored by Gary Oldman’s weary charisma — but critics flagged the run as the show’s weakest. Audiences disagreed, awarding the opening episodes solid IMDb scores. For UK viewers, the access question is simple: Apple TV+ or nothing. And with Season 6 already confirmed, Gary Oldman’s Jackson Lamb isn’t leaving screens anytime soon.
