When Does ‘Slow Horses’ Season 6 Episode 6 Drop on Apple TV+?

If you’ve been glued to the screen for the twists, the bruising action and that surprising kiss in Episode 5, you’re probably wondering when the curtain falls on Season 6. The answer is right around the corner, and the timing is a little quirky, as Apple TV+ tends to do.

Apple TV+ officially lists the Season 6 finale – Episode 6, titled “Judgment Day” – as premiering on Wednesday, October 21, 2026. However, the service has a habit of dropping the episode a day early, at 9:00 p.m. ET on Tuesday, October 20. So if you’re impatient (who isn’t?), set a reminder for that Tuesday night.

Season 6 sticks to the familiar six‑episode format that fans have come to expect. The arc builds steadily, and the final episode promises to bring the safe house drama to a head, with Lamb (Sir Gary Oldman) and Taverner (Kristin Scott Thomas) finally joining forces, while Sid (Olivia Cooke) and River (Jack Lowden) face their own reckonings.

And yes – there’s a Season 7 on the horizon. Apple TV+ has already renewed the series for both Seasons 7 and 8. The next instalment is slated for Fall 2027 and will adapt Mick Herron’s eighth Slough House novel, Bad Actors. Expect more bureaucratic intrigue, more chaos at Slough House, and, of course, more of the signature slow‑horse mischief.

For those who haven’t caught up yet, you can stream all previous episodes on Apple TV+. New subscribers can enjoy a seven‑day free trial, and the service runs a single ad‑free plan at $14.99 per month. There’s also a bundle that includes Peacock for the same price, if you like a little extra variety.

So, mark your calendars: Tuesday, October 20 at 9 p.m. ET for the early drop, or Wednesday, October 21 if you prefer the “official” date. Then, keep an eye out next fall for the next chapter of the Slough House saga.
