In reviews for season four, New York Times wrote: "Slow Horses remains one of the most entertaining and well-put-together shows around", while The Times said the show was "utterly brilliant".

In a review for season three, Slate said: "Slow Horses continues to stand head and shoulders above its streaming peers when it comes to sharp and truly bingeable TV."
Slow Horses has already been confirmed to be coming back for a seventh season, with Apple TV's creative director for Europe Jay Hunt saying in a statement at the time that the highly-praised series "has won fans all over the world with its unique mix of self-deprecating British humor and high-octane action".
"I'm delighted viewers will have another season to enjoy Gary's magnificent performance as Jackson Lamb alongside the Slow Horses' slightly inept spycraft," Hunt added.
Slow Horses season 6 will premiere on Apple TV from 16 September. Seasons 1–5 are streaming now.
