The first season was a huge hit when it first arrived last year, leading to a quick renewal for this second outing, which sees rival gangs jostling for position in the city following the downfall of the McIntyre family.

But, as fans binge their way through the six new episodes, will the series be coming back for a third season beyond them, or is this the last time we'll be heading to this version of Belfast?

Read on for everything you need to know about Blue Lights season 3.

Will there be a Blue Lights season 3?

There will! In fact, Blue Lights was renewed not only for a third season, but also for a fourth on before the second was released, in February 2024.

Speaking when the renewal was announced, creators Declan Lawn and Adam Patterson said: "We’re thrilled that the BBC is committing to Blue Lights in this way. From the beginning, we wanted to write a show that had scale and ambition in its storytelling, and this decision gives us everything we need to do that.

"Thanks to the BBC, to Two Cities/STV and Gallagher Films, and to our brilliant cast and crew. But most of all thanks to our audience who have responded so powerfully to the show. Time for us to get to work!"

When will Blue Lights season 3 be released?

We don't yet know exactly when Blue Lights season 3 will be released, but given that season 2 has arrived just over a year after the first, and the renewal for season 3 came ahead of time, we'd imagine a similar release schedule will continue to be followed.

We would therefore expect that Blue Lights season 3 will arrive on BBC One and BBC iPlayer in Spring 2025, either March or April.

Speaking at a Q&A for the series, Lawn explained how the early renewal for season 3 has impacted writings, saying: "It’s wonderful.

"It’s a great vote of confidence in the whole team and everyone involved. Creatively though, for us as writers, it gives us a great deal of certainty, and it means we can plan the story arcs now over 12 episodes instead of six, which we're really excited about.

"It's kind of like you're doing a painting on a small page and then someone says, ‘Here's a big canvas’. So it feels creatively very, very exciting."

Lawn also suggested that it might take either two or three years for both seasons 3 and 4 to come out, perhaps hinting towards a slight delay, either between seasons 2 and 3 or 3 and 4. We will update this page once we know anything further.

Who will return to star in Blue Lights season 2?

We don't yet know exactly who from the Blue Lights cast will be returning for season 3, and it depends somewhat on how season 2 ends, and whether everyone makes it out alive.

However, we would imagine that most of the central cast will be back, including Sîan Brooke as Grace, Martin McCann as Stevie, Katherine Devlin as Annie and Nathan Braniff as Tommy.

Here's a list of the season 2 cast who could return for season 3:

  • Siân Brooke as Grace Ellis
  • Martin McCann as Stevie Neil
  • Katherine Devlin as Annie Conlon
  • Nathan Braniff as Tommy Foster
  • Joanne Crawford as Helen McNally
  • Andi Osho as Sandra Cliff
  • Hannah McClean as Jen Robinson
  • Paddy Jenkins as Happy Kelly
  • Desmond Eastwood as Murray Canning
  • Jonathan Harden as Jonty
  • Andrea Irvine as Nicola Robinson
  • Frank Blake as Shane Bradley

Is there a trailer for Blue Lights season 3?

Given that Blue Lights season 3 hasn't begun filming just yet, there isn't a trailer available at this point. We'll add one in as soon as it's available, but for now you can rewatch the trailer for season 2 right here.

Blue Lights season 2 is available to stream in full on BBC iPlayer.
