ITV3 TV Guide: Listings, Schedule & What’s On ITV3 Tonight

ITV3 is ITV’s drama channel, launched on 1 November 2004 as a home for the broadcaster’s back catalogue of detective series, period drama and classic sitcoms. Midsomer Murders, Vera, Wycliffe, Inspector Morse: if it involves a body in a village and a detective who doesn’t much like being interrupted, it has probably run here. Tonight, Monday 10 August 2026, a Heartbeat double leads into the evening from 5:50pm, Midsomer Murders takes the 8pm slot, Grantchester runs twice from 10pm, and Trial and Retribution opens its two-part case at 11:50pm.

ITV3 Schedule: Monday 10 August 2026 (Full Listings)

Here is the complete ITV3 schedule for Monday 10 August 2026, on Freeview 10.

What’s on ITV3 today

Daytime on ITV3 keeps to its usual detective and soap-repeat rota, and today is a good example. Trigger Point opens proceedings at 12:55am, a George and Mildred episode and a short Unwind with ITV wellbeing filler take the schedule past 2am, and teleshopping fills the gap from 2:30am until George and Mildred returns properly at 6am with two episodes back to back. A single Classic Emmerdale episode runs from 7:05am, then two episodes of Classic Coronation Street from 8:10am lead into a pair of early Suchet cases from Agatha Christie’s Poirot, the two-part Peril at End House. Heartbeat holds the late morning with two episodes from 11:35am, Midsomer Murders makes its first appearance of the day at 1:35pm with A Grain of Truth, an early Barnaby case built around a struggling organic bakery, and the schedule then repeats the pattern in reverse: Classic Emmerdale twice from 3:35pm, Classic Coronation Street twice from 4:40pm, and Heartbeat twice more ahead of the evening.

ITV3 tonight — primetime and the evening schedule

Here’s the ITV3 primetime line-up for tonight, Monday 10 August 2026.

Heartbeat — ITV3, 5:50pm & 6:55pm

The evening opens with a Heartbeat double. Skeletons and Cupboards has Ventress questioning his own sanity after Blaketon spots a man they’d both certified dead fifteen years earlier, and A Girl’s Best Friend follows straight after, with Mike finding that money hasn’t brought a local couple much happiness and Vernon dabbling in hypnotism.

Midsomer Murders — ITV3, 8pm

The Oblong Murders is the main event tonight, and it gets the full two hours from 8pm to 10pm, ITV3’s longest single item of the evening. Barnaby sends Jones undercover into a New Age cult after one of its members goes missing, and the case turns towards a boat explosion partway through the investigation. It’s a slower build than the Heartbeat double that opens the night, which suits the extra runtime.

Grantchester — ITV3, 10pm & 11pm

Two episodes run back to back from 10pm. A circus arrives in Grantchester and one of its performers is found shot dead with a crossbow bolt in the first. A hotel manager’s death and an abandoned baby complicate the second.

Trial and Retribution — ITV3, 11:50pm

Curriculum Vitae opens its two-part run close to midnight. The case begins when a mother gets back from her shift to find her baby dead at home and the nanny gone.

What kind of shows are on ITV3

Detective drama and cosy crime

The backbone. Midsomer Murders, Vera, Inspector Morse, Endeavour and Wycliffe cover roughly four decades of British detective television between them, and ITV3 works through them in long runs rather than one-off repeats. You can usually pick a series up mid-week and stay with it.

Period and literary adaptation

The Darling Buds of May, and Agatha Christie’s Poirot when it comes round — David Suchet played the part across thirteen series for ITV between 1989 and 2013. These tend to be scheduled in full-series blocks.

Classic sitcom

George and Mildred and its ITV contemporaries fill the overnight and early-morning slots. Nobody’s setting an alarm for these; they’re on while the day gets going.

How to watch ITV3

Channel numbers

Here’s where to find ITV3 across the main UK television platforms:

Free on all of them, no subscription. Numbers shift regionally, so check your on-screen guide if one doesn’t match.

Streaming online

ITV3 streams live and free through ITVX, at itv.com/watch and via the ITVX app on smart TVs, mobiles, tablets and most games consoles. A free account is all that’s needed, no payment details. The ITVX library also carries individual episodes and full boxsets from the channel, Vera and Poirot included, if you’d rather not wait for a repeat to come round.

ITV3 +1 and sister channels

The +1 channel is less useful than it used to be. Since November 2023 it has broadcast only a reduced overnight window rather than a full hour-behind simulcast, so if you’ve missed the start of something, ITVX catch-up is the better bet.

ITV3 sits alongside ITV1, home to Coronation Street, Emmerdale and the network’s biggest primetime shows, and ITV4, which handles sport, action films and older action series.

Verdict

ITV3 has never pretended to be about new television, and today is a fair illustration of what that means in practice: archive soaps through the afternoon, two Poirot cases, two Midsomer Murders outings, and a run of primetime repeats carrying the channel past midnight. Depth is the whole proposition. If you already know the channel, a Monday like this needs no explanation. If you don’t, it’s still one of the easier ways into British detective drama on Freeview, since you can drop into almost any afternoon or evening and land halfway through something worth finishing.
