BritBox, PBS Masterpiece, and Acorn TV are responsible for the majority of the new British TV shows streaming in the US each month – but there are another 5-10 services that frequently offer new British TV premieres, and if British TV isn't your full-time job, it can be hard to keep track of what's coming out. To help, we put this list together each month to make it easy to locate shows which:

  • Premiered in the UK or Ireland within the last year or two
  • Are having their US streaming premiere in September 2025

Things always start to heat up when the weather cools down, and while the absolute numbers for September may not look great, the quality is extremely high across the board.

13 New British TV Shows Coming to the  US in September 2025

Lynley premieres September 4th

Lynley, Season 1 (2025)

An aristocratic detective in a blue-collar squad, Tommy Lynley (Leo Suter) stands apart; Barbara Havers (Sofia Barclay) has little patience for pedigree or protocol. Pushed onto the same caseload, they learn to trade strengths—his reach and strategic calm, her instincts and refusal to defer—to solve what others can’t. The friction becomes a working method, and the job becomes their common ground.

Four feature-length episodes will premiere on a weekly basis over four weeks on BritBox. Watch it HERE.

Wish lists span period charm, gardens, annexes for multi-generational living, space for hobbies or home businesses, and coastal or hill views.

Their caseload ranges from suspected exploitation of elderly victims to the reappearance of a hammer-wielding attacker, a dismembered hand retrieved from a canal, and an unexplained death mid-flight.

Daniel must delve under the veneer of village life to piece together clues and uncover long-buried secrets, navigating the press and public eye and the ire of his superior, the bishop. Daniel is
