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

Published: 17 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. Tonight, Friday 18 September 2026, an overnight of classic crime drama and soap reruns gives way to Inspector Morse holding the late-morning slot for over two hours. Two Heartbeat episodes open primetime, then Doc Martin runs two episodes back to back from 8pm, Downton Abbey follows at 10pm, and Scott and Bailey closes the night at 11:10pm. There’s no Midsomer Murders, no Vera and no film today.

ITV3 tonight — primetime and the evening schedule

Here’s the ITV3 primetime line-up for tonight, Friday 18 September 2026.

Heartbeat — ITV3, 6:55pm

The second of two early-evening Heartbeat repeats eases the schedule into primetime, Aidensfield’s village bobbies handling the usual mix of minor crime and small-town gossip.

Doc Martin — ITV3, 8pm

Two episodes run back to back from 8pm, Martin Clunes’ irascible Portwenn GP alienating patients he’s supposed to be treating, through to Downton Abbey at 10pm.

Downton Abbey — ITV3, 10pm

Series two of the Crawley family saga continues at 10pm, the household adjusting to life during the First World War.

Scott and Bailey — ITV3, 11:10pm

The Manchester-set police procedural closes the night from 11:10pm, DC Janet Scott and DC Rachel Bailey working through another case.

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.

That long-run scheduling shows up starkly in the data. Across 48 days we logged 933 ITV3 slots drawn from just 26 different programmes, with Heartbeat alone accounting for 138 of them — the most concentrated schedule on Freeview. For a nostalgia channel that is arguably the product working as intended; the full figures are in our study of repeats on UK television.

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.

Frequently asked questions

Verdict

ITV3 has never pretended to be about new television, and today leans on the channel’s usual rotation rather than any single event. Inspector Morse holds the late-morning slot for over two hours, and a run of Classic Emmerdale and Classic Coronation Street episodes fills much of the rest of the day.

The evening has a clearer shape: two Heartbeat episodes lead into two Doc Martin episodes from 8pm, then Downton Abbey at 10pm and Scott and Bailey to close. Nothing here is new, and there’s no film today, but it’s a schedule built for detective-drama regulars happy to settle into a familiar rhythm.
