The police drama starring Sian Brooke, Katherine Devlin and Nathan Braniff is back for a third run
Blue Lights is back for a third series, with the BBC promising “more high-stakes, gripping moments than ever before”.
The police drama became a huge hit after it launched in 2023, with viewers calling it “the best thing on TV”. A second run followed last year, drawing more viewers who were gripped by life at the fictional Blackthorn police station in Belfast.
Blue Lights’ third run is now here, with fans set to be plunged into a dark world lurking beneath the surface of middle-class life in Belfast “as the collapse of the old political and criminal order has paved the way for a new era of global gangs”.

When is Blue Lights on?
Blue Lights returns to TV screens tonight (Monday September 29). It is set to air on BBC One and iPlayer from 9pm.
Who is in the cast of series 3?
Sian Brooke is back as Grace Ellis, Katherine Devlin is returning as Annie Conlon and Nathan Braniff is reprising the role of Thomas Foster, with the trio no longer new recruits at the station.
Martin McCann is returning as police officer Stevie Neill, while Joanne Crawford is also picking up where she left off as Inspector Helen McNally.
There are also some new faces in the show, with Boiling Point’s Cathy Tyson playing Dana Morgan, a private club proprietor, and Bad Sisters’ Michael Smiley starring as new intelligence officer Paul ‘Colly’ Collins.
What happens in series 3?
Blue Lights series three picks up with response officers Grace, Annie and Tommy, who are now two years into their jobs.
The new batch of episodes will see them challenged as their work takes them into an underworld where accountants and lawyers facilitate organised crime.
Meanwhile, a new gang rules Belfast, “bringing danger closer to home for our officers than ever before”.
Declan Lawn, who co-created the police procedural with Adam Patterson, said: “Series three looks at the professional apparatus alongside organised crime, and how paramilitaries in Belfast are often in thrall to international organised crime gangs using the territory as a stopping off point for large scale drug smuggling.”
“It also looks at sexual exploitation of kids in care,” he said. “These storylines are entirely fictional but informed by careful research so have a real authenticity.”
How many episodes will there be?
The crime show is following the pattern of previous series, with the new series comprised of six episodes.
Blue Lights series three is on BBC One and iPlayer from 9pm on Monday September 29.
