Slow Horses: Apple TV+’s Acclaimed Spy Drama Expands with New Season and Major Changes Ahead

A New Chapter for the Celebrated Spy Series

The highly anticipated fifth season of ‘Slow Horses’ is set to premiere on Apple TV+ on September 24, 2025, with two episodes launching initially, followed by weekly releases until October 22.

The series continues to receive extraordinary acclaim, with its third season earning a remarkable 98% approval rating on Rotten Tomatoes. Critics have praised it as ‘superb,’ noting that it delivers ‘what might just be Slough House’s most compelling operation yet’.

Major Developments and Changes

A significant change is coming to the series as Will Smith, the Emmy-winning creator who has served as writer and executive producer, will be departing after Season 5. Smith has been the driving force behind the show, functioning as the de facto showrunner since its inception.

The upcoming season promises intrigue as the story follows an unusual premise: ‘Everyone is suspicious when resident tech nerd Roddy Ho has a glamorous new girlfriend, but when a series of increasingly bizarre events occur across the city, it falls to the Slow Horses to work out how everything is connected. After all, Lamb knows that in the world of espionage, the London Rules — cover your back — always apply’.

Continued Success and Future Plans

The series has been hailed as ‘undoubtedly the best spy series on television’ and a ‘truly epic espionage thriller.’ Its excellence has been recognized with multiple accolades, including nine Primetime Emmy Award nominations for its third season, securing a win for Outstanding Writing for a Drama Series.

Looking ahead, Apple TV+ has already renewed ‘Slow Horses’ through Season 7. The series will continue under new creative leadership, with Gaby Chiappe taking the reins for Season 6, followed by ‘All Creatures Great and Small’ creator Ben Vanstone for Season 7.
