Where Is Line Of Duty Set

You know that feeling when you’re deep into a Line of Duty binge, and someone walks in asking, “Where is this even set?” You’re too busy squinting at a grainy interview to answer, but it’s a fair question. The show doesn’t slap a big “Welcome to” sign on the screen, and the action jumps around a lot. But if you’ve ever wondered why all the concrete looks suspiciously damp, you’re about to get the answer.

The simple, honest truth is that Line of Duty is mostly set in the fictional city of Central Police—a made-up patch of northern England that feels like every rainy Friday you’ve ever had. It’s a blend of Birmingham, Manchester, and Liverpool, all smashed together like leftovers in a Tupperware. The show’s creators did this on purpose, so you can’t pin the corruption on one real town.

Real places, fake crime

While the city is fictional, the actual filming happens in very real, very relatable spots. The bulk of the action was shot in and around Belfast, Northern Ireland, which is a bit like using your sister’s living room to film a family drama set in your own house. They used Belfast to stand in for that generic Northern city, mainly because the streets there look suitably grim and the tax breaks were good.

You’ll spot the Belfast City Hospital standing in for the police station’s exterior, and those dodgy car parks are probably just normal car parks in Belfast. It’s a bit like when your mate says they’re going to “the city” but actually means the next town over. You just nod and go with it.

That iconic flipping interview room

Let’s be honest, the most famous “location” in the whole show isn’t a city—it’s that tiny, suffocating interview room. You know the one: gray walls, a chipped table, and a camera that makes everyone look guilty. It feels like the waiting room at the DMV, but with more shouting and threats of jail time.

That room was actually built in a studio in Belfast. So when AC-12’s boss, Superintendent Hastings, bangs the table, he’s technically banging a table in a room that smells like craft services and nervous sweat. It’s oddly comforting to know that even the most intense confrontations happen in a place that looks suspiciously like your office’s break room after a bad Monday.

Why it feels like your own city

The genius of the setting is that it’s deliberately generic. Every time you see a wet street or a concrete car park, your brain says, “Oh, I’ve been stuck in traffic there.” The show avoids famous landmarks like Big Ben or the Gherkin, because terrorism and cover-ups are scarier when they could happen in your back garden.

I once watched an episode and saw a row of terraced houses that looked exactly like the street where my aunt lives in Leeds. I texted her, “Are you in Line of Duty?” She replied, “No, that’s just my neighbour’s damp wall.” It’s that kind of accidental relatability that makes the show feel real.

The London fake-out

Don’t be fooled when characters mention “the Met” or you see a black cab. Sometimes the show jolts you to London for a fancy meeting, but it’s really just a quick trip to a different studio lot. It’s like when a sitcom character “goes to Paris” but you know they’re just standing in front of a green screen.

And yet, that doesn’t matter. The real “setting” of Line of Duty is the tension in your own chest. Wherever the characters are—a damp alley in Belfast or a fake London office—you’re just waiting for the next person to say “bent coppers” and ruin their life with a single interview.

Home is where the Hastings is

Ultimately, the show is set in a place we all recognise: a world of bureaucratic nightmares and water-cooler gossip. It’s the feeling of being stuck in a workplace where everyone has a secret, and HR is just a front for a major conspiracy. The actual geography is irrelevant.

You don’t need to know if AC-12 is in Birmingham or Belfast to enjoy the show. You just need to know that the car park where Arnott gets jumped is the same one you’d use after a late shift at your own job. And that the rust on the fire escape is the same rust you ignore every day.

So next time someone asks you where Line of Duty is set, just shrug and say, “It’s set in your neighbour’s damp wall, your office break room, and a rainy car park you saw once on a holiday.” And maybe add that it’s all filmed in Northern Ireland, but nobody talks about that because Hastings would call it “unsatisfactory.”
