Professor T keeps pulling people in with its mix of clever crime puzzles, eccentric personalities, and a surprising amount of heart. The British drama, which follows the brilliantly awkward Professor Jasper Tempest, was officially renewed for Season 5 back in February 2025 — and fans have been buzzing ever since. So, when can we expect it, who’s returning, and what’s next for the Cambridge crew?
Release Date Speculation for Professor T Season 5
Right now, there’s no confirmed release date for Professor T Season 5, but the show’s past schedule gives us a decent idea. In the UK, it airs on ITV and ITVX, while US viewers catch it on PBS, Prime Video, and Apple TV+. Season 1 arrived in June 2021, Season 2 followed in September 2022, Season 3 came out in March 2024, and Season 4 is expected to drop around September or October 2025.
Cast: Who’s Returning for Professor T Season 5?
The show’s magic comes from its tight-knit cast, and Season 5 will keep the core crew. Ben Miller’s back as Professor Jasper Tempest, the OCD criminologist who’s equal parts brilliant and messy. He’s teased “fun, emotional, and surprising” twists for Jasper. Frances de la Tour returns as Adelaide Tempest, Jasper’s mom, with more warmth and drama in her story. Juliet Stevenson’s set to play Dr. Helena Goldberg again, Jasper’s therapist, who might face some tricky personal moments.
Barney White’s back as DS Dan Winters, taking on a bigger role after Season 3’s gut-punch ending. Sunetra Sarker returns as DCI Maiya Goswami, steering the police team through rough waters. Emma Naomi’s DS Lisa Donckers won’t be back after her character’s tragic exit in Season 3. New faces are expected to spice things up, though no names are out yet. Look for characters like Mike Watson and Zoe Hanna to keep things lively.
Plot Details: What to Expect in Professor T Season 5
Season 5 will dive into the aftermath of Season 4’s chaos, serving up six episodes of twisty crimes and personal arcs. Think deadly boxing matches and weird deaths at a posh spa—cases that’ll test Jasper’s sharp mind as he helps the Cambridge cops. Jasper’s got new relationships brewing and a musical side project that’ll show a softer vibe. Adelaide’s love life will tug heartstrings, while Dan and Maiya deal with team shake-ups and tough cases.
The season will lean into Jasper’s struggles with OCD and maybe autism, as Ben Miller’s hinted in interviews. Cambridge’s stunning scenery will keep the mood intense. Expect the show’s classic mix of wit, heart, and dark mysteries, with a few curveballs thrown in.
