Professor T returns to ITV1 on Wednesday 19 August at 9pm, with Ben Miller back in the Cambridge-set crime drama for season four. The UK run comes after season four had already aired in the US, turning this into a delayed local launch rather than a fresh global debut.
Season three ended in May 2024, when DS Lisa Donckers was struck in a hit and run. That cliffhanger gives the new run a built-in reset point, and Stephen Brady says the new episodes will chart a new path with original stories.
Stephen Brady resets the board
"We've taken the stabilisers off!" Stephen Brady told Radio Times while teasing the new season. He also said, "Like most actors, Ben knows the character a bit better than me," which points to a writing process that leans on the lead actor's read of Professor Tempest rather than simply repeating the older template.
That matters because Professor T is based on the Belgian series of the same name, yet the UK version has already moved beyond a simple remake. The new season is being framed as a step away from the source structure and toward stories built specifically for this run.
May 2024 to August 2025
More than two years separate the season three finale in May 2024 from the ITV1 launch on Wednesday 19 August. Nearly a year also separates the US airing from the UK debut, so viewers here are arriving late to material already in circulation elsewhere.
For a returning drama, that gap usually changes the viewing pattern: the audience is not catching up on a finished run, but rejoining a show whose story engine has already moved on. Ben Miller's return keeps the series anchored, yet the delayed rollout means the UK premiere now has to sell both the familiar lead and the fact that the story has already shifted.
Season five already set
Season five filming wrapped in August 2025, and Professor T has been commissioned for a sixth season. Zoë Wanamaker will join season five as Zelda Radclyffe, while Frances de la Tour returns as Adelaide Tempest in season five, Juliet Stevenson as Doctor Helena Goldberg in season five, Barney White as DS Dan Winters in season five, Sunetra Sarker as DCI Maiya Goswami in season five, and Rhian Blundell as DC Chloe Highsmith in season five.
For viewers in the UK, the practical takeaway is simple: season four arrives on Wednesday 19 August at 9pm, but the show is already moving beyond it. The bigger story is not just the premiere date; it is that ITV has lined up two more seasons, so the return is the start of a longer run rather than a one-off catch-up.
