Disclaimer: This article contains spoilers for Coldwater Season 1.
Coldwater premiered on ITV on September 14, 2025, and completed its six-episode run with scenes that left many questions open. The show follows John (played by Andrew Lincoln), a man who moves with his family from London to a small Scottish village after a traumatic incident that left him shaken. In the opening episodes, John tries to rebuild home life while his wife, Fiona, pursues a new path.
By the finale, the family faces far deeper danger when their neighbour Tommy, played by Ewen Bremner, is revealed to be violent and secretive. The first run mixes quiet domestic moments with sudden shocks, where John kills a local man in what begins as self-defence, Tommy offers to help but then manipulates the evidence, and later, Tommy’s hidden trophies and a garage full of worrying keepsakes come to light. A showdown leaves John shot and Tommy missing at the end of episode six, while Rebecca, the local vicar, remains in the village and continues to lead her congregation.
To answer the question "Will there be a Coldwater Season 2?", ITV has not officially confirmed a second season.
Current renewal status of Coldwater and what that means for viewers

ITV has not issued a renewal notice. Networks often wait to see viewing figures, audience reaction, and international sales before deciding to order more episodes.
Industry reporting and interviews show the writer, David Ireland, and several cast members are open to further work on the story, but a production start date or formal green light has not been announced. Whether Coldwater will have a Season 2 is therefore an open question that depends on those business factors.
What does the Coldwater season 1 leave available for more plot development?
Season one closes several threads that could be reopened. Tommy’s escape, the police response, and the village’s slow return to normal offer obvious plot points, i.e., a manhunt, a trial that may or may not happen, or deeper probes into Tommy’s past abuse and the unsolved deaths tied to his behaviour. Specific scenes that could be expanded include the men’s group meetings that continued at Tommy’s house and the news appearance where John and Fiona speak about surviving the crisis.
Who might return, and what casting would affect?

Key actors have signalled interest in returning, including Lincoln and Bremner. Rebecca’s presence in the town at the end of episode six means Eve Myles’s role could be central if writers continue the story. A second season would also need to decide how public the truth becomes and whether characters like Fiona and local officials remain sympathetic or shift position.
A realistic timeline if a second run is approved
ITV will have to rely on scripting, casting, and location logistics to determine the production timeline in case the company orders more episodes. Although a large part of Coldwater is shot in Scotland, finding locations and organizing crews might require months. In the event of a green light soon, production on the second season could start next year, with a late 2026 release as a viable possibility.
