Apple TV+ has officially confirmed that its critically acclaimed spy thriller Slow Horses will return for a eighth season, with production set to begin soon. The announcement arrives shortly after the series’ latest Emmy win and continues a steady annual release pattern that has made the show one of streaming’s most reliable offerings since 2022.
The upcoming season will adapt the ninth and most recent book in Mick Herron’s Slough House novel series, Clown Town. This marks another faithful adaptation from Herron’s beloved espionage novels, which have served as the foundation for each installment of the hit television series.
A Winning Streak Continues
The timing of the season 8 announcement is particularly sweet for the production team. Slow Horses recently took home a Primetime Emmy Award, with director Saul Metzstein claiming Best Director for a Drama Series for his work on season 5’s episode 6, “Scars.” The recognition comes as part of an impressive run that has seen each of the show’s five seasons earn Rotten Tomatoes scores above 95% and three consecutive nominations for Outstanding Drama Series.
The announcement also confirms details about the immediately upcoming sixth season. Slow Horses returns on September 16, 2026, running through October 21, 2026. Earlier last year, Apple announced that season 7 would be based on Herron’s Bad Actors, keeping fans well ahead of the production schedule.
“Season 8 sees Jackson Lamb and Diana Taverner face off in their most explosive confrontation yet. When a botched attempt to blackmail the Park puts Taverner on the offensive, it is up to Lamb to unravel one of MI5’s darkest secrets and put an end to it once and for all.”

The World of Slow Horses
According to Apple TV+, Slow Horses is a darkly humorous espionage drama that follows a dysfunctional team of British intelligence agents who serve in a dumping ground department of MI5 known unaffectionately as Slough House. The series stars Gary Oldman as Jackson Lamb, the brilliant but cantankerous leader of the spies who end up in Slough House due to their career-ending mistakes and who frequently find themselves blundering around the smoke and mirrors of the espionage world.
Oldman has received widespread acclaim for his portrayal of Lamb, with critics particularly noting his impressive ability to consume food in the grossest ways imaginable. His performance has become a defining element of the series’ charm, anchoring an ensemble cast that has grown increasingly beloved by audiences over five seasons.
Apple TV+’s Expanding Catalog
The confirmation comes during an impressive stretch for Apple TV+, which recently announced that Widow’s Bay won a stunning 14 Emmys, the most ever for a comedy series. The streamer has also revealed that Silo is returning for its fourth and final season, airing less than a year after its third season concluded.
With titles like Pluribus, Severance, Ted Lasso, Shrinking, Margo’s Got Money Troubles, and Pachinko already in its repertoire, Apple TV+ has built an impressive catalog that continues to attract both critical acclaim and dedicated viewership. The Slow Horses renewal adds another strong property to a lineup increasingly recognized for quality over quantity.
Looking Ahead
Fans can expect the sixth season of Slow Horses to arrive on September 16, 2026, with episodes running through October 21, 2026. As production ramps up on season 8 based on Clown Town, viewers have plenty to anticipate from Apple TV+’s espionage franchise that has consistently delivered high-quality storytelling year after year.
