Everything British Worth Streaming in September 2025

Ahhh, September. The windows are finally open, the breeze is cooling down, school's back in session, and summer holidays are a memory. Most importantly, television is ready for families to get back to their usual work schedules and, more to the point, their tired evenings on the couch. September has been the beginning of the television season since the phrase "Television Season" was invented, and 75 years later (give or take) that tradition still holds. 

Even streaming services, especially the ones tied to broadcast networks, tend to debut their biggest hopefuls for new hit shows in the September-October time frame, and the majority of weekly series make their returns. But this year, no streamer is going quite as hard as BritBox, which is literally creating an old-school style "week of debuts" in early September, premiering three Season 1s of brand new series back to back, all three of which are clearly meant to become hits.

The large number of debuts also means every major streaming service has an entry on this list, so buckle in and make sure your logins are working, because there's quite a bit of good British (or British-ish) stuff on the way this month. So let's run down everything British streaming around the apps for September 2025.

The Crow Girl

Eve Myles, Dougray Scott, and Katherine Kelly headline The Crow Girl, a Paramount+ UK original series that never made it to the American version of the streaming service. (Please note, there is still an extensive collection of those.) Another Nordic Noir reset in Scotland, the trio team up to stop a serial killer. The series begins streaming weekly exclusively on Acorn starting Monday, September 8, 2025.

The Red King

Created by Being Human's Toby Whithouse and starring Anjli Mohindra, Marc Warren, and Adjoa Andoh, The Red King is a contemporary police procedural crossed with The Wicker Man. The supernatural elements make it a proper fit for AMC+. It debuts exclusively on the platform with a two-episode premiere on Thursday, September 25, 2025, followed by one episode a week.

Murder Before Evensong

Meanwhile, Acorn TV hopes to continue its cozy-crime trifecta of new debuts, which thus far have included Art Detectives and Irish Blood with Murder Before Evensong, starring All Creatures Great & Small's Matthew Lewis, giving us all his best mystery-solving Hot Priest. The series debuts Monday, September 29, 2025, and streams one episode a week through October.

Slow Horses Season 5

Newly "Sir" Gary Oldman, Jack Lowden, and Kristen Scott Thomas return once again to Slough House for Slow Horses Season 5. The Apple TV spy series has become so popular that it's not only renewed for two more seasons after this one, but will be followed in October by another Mick Herron adaptation, Down Cemetery Road. Plan to watch both. Slow Horses returns with two episodes on Wednesday, September 24, 2025, followed by one a week.

All of You

Everyone is hoping All of You, the first Brett Goldstein rom-com film, could get some traction for awards season. The film debuted earlier this year on the film festival circuit, where Apple TV+ scooped it up, and will do what it can to promote it starting Friday, September 26, 2025, when it debuts on the service as well as a few theaters.

Return to Paradise Season 1

After Ovation scooped up the latest Death in Paradise spinoff, the Down Under set Return to Paradise, earlier this year and made a minor success of it, BritBox discovered it could get over the Australia of it all, and the show will make its debut on the same streaming service in the U.S. that's home to both the parent show and the other spinoff, Beyond Paradise (Season 3 of which debuts in October). Season 1 debuts on Tuesday, September 2, 2025; Season 2 is scheduled for release next year.

Lynley Season 1

BritBox snatches Masterpiece's lunch out from under them with the 2020 era remake of Lynley. (The original adaptation of the novels, The Inspector Lynley Mysteries, aired on Mystery! on PBS in the early aughts.) The new version even stars Sanditon's Leo Suter as the titular DI Tommy Lynley, just to add insult to injury. The series debuts Thursday, September 4, 2025, and streams one episode a week through October.

The Hardacres Season 1

BritBox's trio of Season 1 premieres for the beginning of September rounds out with one of the most anticipated shows to cross the pond, The Hardacres. Based on CL Skelton's two novel opuses, this is the first time the 1890s set rags-to-riches period drama has been adapted for television. Liam McMahon, Claire Cooper, and Julie Graham star. Season 1 will premiere with two episodes on Wednesday, September 10, 2025. Season 2 is already in production.

Escape to the Country Season 32

The British do almost all reality shows better than we do, and that's not an opinion; it's a fact. (That's why, with the sole exception of The Bachelor, every successful reality series in America is a remake of a superior European one.) Escape to the Country is the British version of House Hunters, with endless 30-minute episodes of couples touring estates, all of which have majorly outdated pricing by the time we see them. Season 32 of the mindless fun hits Friday, September 19, 2025.

Silent Witness Season 28

The longest-running procedural series on the BBC today, Season 28 of Silent Witness offers viewers a fresh chance to start watching, as the show marks another soft reboot point. No longer "Moonlighting as a UK Procedural Series," the show has recently morphed into "Partners in Life are Partners in Crime-Solving." An entirely new supporting cast has been magically found to help them in this endeavor. The series debuts Thursday, September 25, 2025; Season 29 is already greenlit.

The Change Season 2

The final season of one of the most hilarious takes on the experience of menopause, Season 2 of The Change, brings back series creator and star Bridget Christie's Linda, who ran away to join the Eel Sisters in Season 1 after hitting her "hot flush" era. (Hot Flush is British for Hot Flash. And listen, if you'd had a hot flash, you'd think running away to live in the forest as an Eel Sister is not the worst life choice.) Season 2 premieres Tuesday, September 30, 2025, and streams weekly through October.

Swiped

More on the British-ish end of things than actually British, Swiped is another Lily James vehicle, which Disney, via streaming service Hulu, is trying to ride to awards season glory solely based on her performance. The film will premiere at the 50th Toronto International Film Festival in the first week of September and then will be followed by a debut on streaming on Hulu (or under the Hulu tile on Disney+) on Friday, September 19, 2025.

Warfare

HBO is out of British shows to debut. However, it does have a British film from A24 debuting that's generating a lot of awards buzz: Warfare. Created by British director Alex Garland along with American veteran Ray Mendoza, the film stars a who's who of male U.K. talent (Will Poulter, Cosmo Jarvis, Kit Connor, Finn Bennett, Joseph Quinn) as American soldiers and is based on Mendoza's real-life experiences in Iraq. The film debuts Friday, September 12, 2025.

The Great British Baking Show Season 16

On your marks, get set, bake! Sure, the last three seasons of The Great British Baking Show have been one long, rolling, Paul Hollywood-created disaster with embarrassingly racist challenges, better bakers sabotaged for his favorites, who aren't actually up to snuff, and last year's unfortunate attempt at recreating the magic of Season 5 with a baker that barely rated, but hope, like yeast, rises every time we here that theme tune. Season 16 debuts on Netflix on Friday, September 5, 2025, and streams weekly until Thanksgiving.

House of Guinness

Steven Knight's third series to debut in America in 2025 after Rogue Heroes Season 2 on MGM+ and A Thousand Blows on Hulu, House of Guinness is the biggest budget series of the three and the most marketed, and will almost certainly be the one everyone watches. I mean, Anthony Boyle and Louis Partridge being hot sibling rivals over stout? It's Peaky Blinders Does Beer, and I'm so here for it. All episodes arrive on Thursday, September 25, 2025.

The 77th Primetime Emmy Awards

Also more British-adjacent than British, the 77th American Primetime Emmy Awards will nonetheless be a celebration of British talent, with Adolescence poised to take home as many trophies as possible, serving as a precursor to potentially sweeping the Golden Globes and Screen Actors Guild Awards in January. The Emmys air in two stages: all the Creative Arts Emmys are condensed into a single broadcast on Saturday, September 13, 2025, and the Primetime Emmys follow the next day on Sunday, September 14, 2025.

The Paper 

The American version of The Office would have run forever if NBC could have found a way to make that happen. Instead, a decade after it ended, it's getting a spinoff, a newsroom comedy called The Paper. If you're wondering why that earns it inclusion on this list, Domhall Gleeson plays the Michael Scott figure, sporting such an impeccable American accent, people will think he's more American than Hugh Laurie. All episodes debut on Peacock on Thursday, September 4, 2025.

Downton Abbey & Downton Abbey Celebrates the Grand Finale

Downton Abbey aired on your local PBS stations and is essentially synonymous with Masterpiece. However, NBCUniversal wants you to know that the series is produced by its sister company, Carnival Films. To that end, it's not only snatched Seasons 1 through 6 from your PBS Passports to debut on Peacock Monday, September 1, 2025, but it also has Downton Abbey Celebrates the Grand Finale, a behind-the-scenes special for the final film, airing on NBC on Wednesday, September 10, 2025, and streaming on Peacock the next day.

The Girlfriend, at first glance, appears to be the stereotypical mom vs. girlfriend fight over a man-child. However, the series, which stars Robin Wright and Olivia Cooke, actually tried to go deeper than the superficial layer and into what drives a mother-in-law to act out against her son, gaining a new woman in his life, and why a daughter-in-law might feel like she's enemy number one, no matter where she goes. All six episodes hit Prime on Wednesday, September 10, 2025.
