Line of Duty season 7 makes triumphant return: BBC orders major six‑part revival—AC‑12 rebranded as the Inspectorate of Police Standards; Belfast filming set for spring

Line of Duty season 7 — LONDON – AC-12 has been disbanded and replaced with the Inspectorate of Police Standards, a new externally led anti-corruption unit set up in response to the failings exposed in previous inquiries; The cast for this 6-part latest instalment have reunited Martin Compston, Vicky McClure and Adrian Dunbar we’ll also welcome back a host of guest stars who will meet destruction as writer/director Jed Mercurio turns up the heat on them; Filming takes place in Belfast from spring 2026. The comeback responds to fan demand and the loose threads left by 2021’s finale, recalibrating the drama around institutional accountability. Nov. 19, 2025
The broadcaster’s shift follows years of speculation and confirmation that the cast and creator , Jed Mercurio, are to return. The commission and the returning threesome were initially outlined in an extensive report.
Story-wise, AC-12’s brief changes: the unit is no more, refounded as the Inspectorate of Police Standards — a development captured in trade coverage by Variety. Count on oversight politics and a sensitive inquiry into a much-honored detective accused of misbehaving.
Production will once again be based in Northern Ireland, and filming is expected to begin in Belfast in spring 2026, according to guidelines compiled by Radio Times.
Fans hoping for a release date should manage their expectations: a UK broadcast is unlikely until 2027, according to The Times‘ scheduling leads.
Mercurio, in his matter-of-fact way, has sometimes been quippy in teasing the show’s thematic shift: “Corruption in this country is supposed to have come to an end while ‘Line of Duty’ was off air, so I’ve had to resort to my imagination,” he said in a statement carried by Hello!
The enormity of the challenge is evident. The season six finale set modern records for a UK drama, averaging 12.8 million viewers, according to Deadline‘s ratings analysis.
But the final one proved more divisive — a sense of ambivalence reflected in contemporary reviews by The Guardian. That tension is what makes Line of Duty season 7 both high-stakes and clearly defined.
For months, principals publicly hedged a prediction about a green light; Adrian Dunbar said he was “waiting for the grown-ups” and would only decide later in 2024 — an answer reported by Yahoo UK that made clear such morsels should be swallowed with more than a couple of grains of salt.
Bringing “The X-Files” back to Belfast also reunites a production ecosystem the show helped pioneer. The city’s hosting of the latest run has already attracted impressive attention at a regional level, as reported in IFTN’s industry bulletin.
Bottom line: Line of Duty season 7 reunites the AC-12 team under a new banner, while reframing them with a more sensitive case and a recalibrated mandate. Plot details are sparse, but casting, the structure , and the show’s schedule are in place — enough to begin the countdown.
