London’s streets still echo with the boom from last season’s finale, and the chatter in pubs, on X, and in WhatsApp groups hasn’t stopped. Trigger Point – that gritty ITV nail-biter about bomb disposal officers sweating over live wires – wrapped its third run just weeks ago on October 26, 2025. Barely had the credits rolled when ITV lit the fuse: season 4 is officially happening. Filming kicked off in June, wrapped by early October, and now the countdown begins. Fans are already dissecting every frame, every cryptic cast post, every behind-the-scenes snap. Here’s everything we know so far.
Trigger Point Season 4 Release Date Speculations
Past seasons give a solid clue. Season 1 detonated in January 2022. Season 2 followed in April 2024. Season 3 landed 18 months later, right on schedule. This time, production moved fast – filming started right after season 3 wrapped, and principal photography ended in early October 2025. Post-production usually takes 4-6 months for a show this effects-heavy.
Do the math: spring 2026 feels likely. March or April fits the pattern. But ITV’s drama slate is stacked – Unforgotten, Grace, and a new Harlan Coben thriller are all in the mix. If editing wraps by December, a late 2025 slot isn’t impossible. Either way, expect a teaser trailer by Christmas. The network loves dropping those mid-winter bombs to keep the hype alive.
Trigger Point Season 4 Expected Cast
Vicky McClure returns as Lana Washington – no surprise there. The former military bomb tech turned civilian expo is the beating heart of the show. McClure’s performance – all clenched jaw, trembling hands, and quiet breakdowns in the van – carries the weight. She’s confirmed, suited up, and already posting sweaty set selfies.
The squad rolls deep:
- Eric Shango (Danny) – the calm voice in the headset, back for more.
- Nabil Elouahabi (Hass Rahim) – the tech wizard who spots the tripwire everyone else misses.
- Maanuv Thiara (DI Amar Batra) – the cop who bridges expo and police worlds.
- Natalie Simpson (DSupt. Marianne Hamilton) – the boss who signs off on the risky calls.
Jason Flemyng’s season 3 villain – the bitter ex-employee turned terrorist – left bodies and questions. His arc felt final, but ripples remain. A copycat? A partner still out there? Don’t rule out a flashback or a new face tied to his grudge.
New cast? Nothing official yet. But a major guest star usually leaks mid-post-production. Last time, Flemyng’s name dropped two months before air. Watch for that.
Trigger Point Season 4 Potential Plot
Season 3 ended with a personal gut punch – someone Lana trusted nearly blew her sky-high. The bomber’s motive tied back to corporate cover-ups and old military contracts. That thread didn’t snap clean. Season 4 will likely pick it up: revenge from the inside, a mole in the expo unit, or a whistleblower gone rogue.
Expect:
- More homegrown threats – think disgruntled veterans, hacked drones, or 3D-printed bombs.
- Lana’s trauma front and center – grief, guilt, and the toll of too many close calls.
- Tighter team dynamics – trust issues, new recruits, maybe a romance that blows up (literally).
The show’s strength? Real bomb tech. Consultants from the British Army’s EOD units check every scene. No Hollywood “cut the red wire” nonsense. Season 4 promises the same: sweat, silence, and the hiss of a timer counting down.
