Blue Lights has been renewed for a fourth series
Here are all the details we know so far
Following the dramatic finale of Blue Lights series three on Monday 3rd November, fans of the Belfast-based crime drama will be thrilled to know the show has already been commissioned for a fourth instalment.
Will there be a fourth series?
Yes, yes, yes! Way back in February 2024, before series two had even aired, BBC bosses announced Blue Lights had been renewed for a third and fourth series.
Lindsay Salt, BBC Director of Drama said at the time: “We were bowled over by the reaction to Blue Lights and I’m really pleased to be confirming our commitment to bring two more series of our beloved Belfast drama to air. Adam and Declan have brilliant ideas about where to take the characters next and I can’t wait for viewers to see what’s in store.”
Co-creators, Writers, Directors and Executive Producers, Declan Lawn and Adam Patterson added: “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!”
