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

Published: 3 September 2026

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, Lewis, Poirot, Heartbeat: if it involves a village, a body and a detective in no hurry to leave, it has probably run here. Today, Friday 4 September 2026, the day runs to ten programme titles across twenty-two slots, with Classic Emmerdale getting four outings and Classic Coronation Street three, through the morning and afternoon. Primetime is led by the second of a Heartbeat pair at 6:55pm, then two consecutive Doc Martin episodes at 8pm and 9pm, Agatha Christie’s Marple at 10pm and Poirot closing the night at 11:50pm. There’s no film today.

What’s on ITV3 today

Overnight, George and Mildred plays out at 2am (series 1, episode 6), then teleshopping fills the schedule from 2:30am through to 6am.

The classic sitcom returns for two more episodes at 6am and 6:35am, both from series 4, before the day’s first archive soap block: Classic Emmerdale at 7:05am and 7:35am, then a single Classic Coronation Street at 8:40am, all dating from 2009. Poirot takes the late-morning slot from 9:10am with a feature-length case centred on a spate of thefts and murders at a London student hostel, and Heartbeat opens at 11:30am with the first of two consecutive series 13 episodes, the second following at 12:35pm.

A feature-length Midsomer Murders case, drawn from an early series, fills mid-afternoon from 1:35pm. The archive soaps come round again from 3:40pm: two more Classic Emmerdale episodes at 3:40pm and 4:10pm, then Classic Coronation Street twice more, at 4:40pm and 5:15pm. Heartbeat closes out early evening with its second consecutive pair, at 5:50pm and 6:55pm, before Doc Martin takes the 8pm and 9pm hours, Agatha Christie’s Marple follows at 10pm, and Poirot rounds off the night from 11:50pm. Seven of today’s twenty-two slots belong to the two archive soap strands.

ITV3 tonight — primetime and the evening schedule

Here’s the ITV3 primetime line-up for tonight, Friday 4 September 2026.

Heartbeat — ITV3, 6:55pm

This is the second of tonight’s two Heartbeat episodes, following series 13 episode 15 at 5:50pm. Episode 16 carries straight on from there, with Aidensfield’s police station working through its usual run of small-town cases.

Doc Martin — ITV3, 8pm

Two Doc Martin episodes run back to back from 8pm: series 9 episode 6, “Equilibrium”, followed directly by episode 7, “Single White Bevy”. Martin Ellingham’s bedside manner hasn’t mellowed, and both episodes lean on the gap between his diagnostic skill and his patience for the people of Portwenn.

Doc Martin — ITV3, 9pm

“Single White Bevy” picks up straight after “Equilibrium”, so the pair plays better watched together than split apart.

Agatha Christie’s Marple — ITV3, 10pm

Agatha Christie’s Marple sends its amateur detective to the Caribbean for series 6 episode 1, “A Caribbean Mystery”. A recuperative holiday among the hotel guests turns, as it usually does for Miss Marple, into a murder investigation.

Agatha Christie’s Poirot — ITV3, 11:50pm

The night ends with Agatha Christie’s Poirot and series 7 episode 1, “The Murder of Roger Ackroyd” — one of the most talked-about entries in the whole run, thanks to a narrative device rather than the murder itself. Worth catching from the start.

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’s line-up leans hard on the archive: ten programme titles across twenty-two slots, seven of which belong to Classic Emmerdale and Classic Coronation Street. Around them, Poirot and two Heartbeat pairs fill the morning and afternoon, and a feature-length Midsomer Murders case from an early series takes the mid-afternoon slot. Primetime doesn’t add a single new commission, but it keeps its usual shape: the second of the day’s Heartbeat pairs at 6:55pm, two consecutive Doc Martin episodes at 8pm and 9pm, Agatha Christie’s Marple at 10pm and Poirot closing the night from 11:50pm through to 2am. There’s no film today. It’s a schedule built for one kind of viewer rather than several, and if cosy detective drama and a double helping of soap nostalgia is what you’re after, today delivers plenty of both.
