The biggest new UK TV and streaming shows landing on Netflix, Prime Video, Disney+, Paramount+ and Sky/NOW (14–20 September 2026)

Autumn has well and truly arrived, and with it comes one of the busiest weeks of new television in recent memory. From the return of a true-crime anthology juggernaut to a spin-off built around one of thriller fiction’s most beloved supporting characters, the week of 14–20 September 2026 has something for practically every kind of TV and streaming viewer. We’ve combed through Netflix, Amazon Prime Video, Disney+, Paramount+ and Sky/NOW to round up seven new arrivals worth clearing your schedule for.

Netflix: Monster: The Lizzie Borden Story

Ryan Murphy’s Monster anthology has become appointment viewing since it first tackled Jeffrey Dahmer, and its fourth instalment arrives on Netflix on 17 September. Monster: The Lizzie Borden Story turns its attention to one of America’s most enduring unsolved mysteries: the 1892 axe murders of Andrew and Abby Borden in Fall River, Massachusetts, and the trial of their daughter Lizzie, who was accused and ultimately acquitted of the killings. True to the anthology’s style, the series digs into the psychology of its central figure rather than settling for a straightforward whodunnit, using the case as a lens on Gilded Age gender politics, family repression and the media circus that turned Lizzie Borden into a folk legend. Expect the same blend of prestige performances and unflinching production design that made the earlier seasons such a talking point, alongside plenty of fresh debate about how much of the story is fact versus dramatic licence.

Netflix: The Perfect Lie

Landing a day later on 18 September, The Perfect Lie is a new Dutch drama adapted from a best-selling novel. The series follows four couples whose lives look enviably put-together from the outside: good jobs, good marriages, good friends. That illusion shatters after a tragedy forces all four pairs to confront the secrets they have been keeping from their partners and from each other. Billed as a slow-burn mystery with a strong emotional core, it’s part of Netflix’s ongoing push to bring more European-language originals to a global audience, and fans of twisty ensemble dramas along the lines of Big Little Lies should find plenty to enjoy.

Prime Video: Neagley

Reacher fans have a new reason to log on to Prime Video from 16 September, when Neagley spins off one of the flagship show’s most popular characters into her own series. Frances Neagley is a private investigator working the streets of Chicago and a former protégé of Jack Reacher from their days together in the military police. When a friend turns up dead under suspicious circumstances, Neagley puts her formidable investigative instincts to work, unravelling a conspiracy that reaches further than she expected. The spin-off promises the same lean, propulsive action-thriller energy that has made Reacher one of Prime Video’s most reliable hits, this time filtered through a sharper, more procedural lens as Neagley works cases the traditional authorities can’t or won’t touch.

Disney+: Made in Korea, Season 2

Disney+ subscribers who like their dramas high-stakes and morally murky should already be keeping tabs on Made in Korea, whose second season began earlier this month and continues with new instalments through the week of 14–20 September. Set nine years after the events of the first season, the story follows Baek Kitae, who has climbed the ranks to become Deputy Director of the Korean CIA while quietly expanding a sprawling drug empire. His old nemesis, the prosecutor Jang Geonyoung, resurfaces after years in hiding, determined to finally bring him down. With both men now willing to break any rule to destroy the other, the season builds towards a reckoning that fans of Korean crime dramas have been anticipating since the finale of season one. It’s a reminder that some of the platform’s most compelling new viewing isn’t a Marvel or Star Wars title but a slick, internationally produced thriller.

Paramount+: MobLand, Season 2

Guy Ritchie’s crime saga MobLand returns for a second season on Paramount+ on 18 September, and the Harrigan crime family have never looked more exposed. With Tom Hardy back as the family’s ruthless fixer, this run finds cracks forming in the clan’s once-untouchable empire as rising rivals sense weakness and start to circle. Pierce Brosnan and Helen Mirren also return, lending the ten-episode season the kind of star power that helped the first outing become one of Paramount+’s buzziest originals in TV and streaming. Expect the same mix of blood-soaked family politics and dark humour, with the power struggle at the heart of the Harrigan dynasty pushed to breaking point.

Sky/NOW: The Walking Dead: Dead City, Season 3

Zombie drama fans have plenty to look forward to on 18 September, when The Walking Dead: Dead City returns for its third chapter on Sky and NOW. Maggie and Negan are back for another instalment of the spin-off, which relocated the long-running franchise’s survivors to the ruins of a walled-off Manhattan. The show has carved out its own identity within the wider Walking Dead universe by leaning into the strange, almost gothic atmosphere of a city reclaimed by the dead, and this new season promises to push the uneasy alliance between its two leads even further.

Sky/NOW: Saturday Night Live UK, Season 2

Finally, comedy fans should keep 19 September free for the latest live instalment of Saturday Night Live UK, which returned for its second series this month on Sky Comedy and NOW. The British adaptation of the iconic American format sees a fresh crop of home-grown comedians take on sketch comedy and topical news satire in front of a studio audience, broadcast live each Saturday night in the now-familiar SNL style. After a first series that divided critics but built a genuine following, the show’s producers have promised sharper writing and starrier guest hosts for round two, making it one of the more unpredictable, of-the-moment options in an otherwise scripted-heavy week.

The Bottom Line

Whatever your TV and streaming mood calls for this week — a grisly true-crime deep dive, a slow-burn European mystery, a hard-boiled detective spin-off, a K-drama power struggle, a gangster saga, some post-apocalyptic horror or live sketch comedy — the UK’s major streaming services have it covered. With five different platforms all launching new content within days of each other, 14–20 September 2026 shapes up to be one of the more crowded, and rewarding, weeks of the autumn TV and streaming calendar.
