The first two ITV1 broadcasts
Adultery begins on ITV1 on Sunday 25 October 2026 at 21:00 UK time. The official programme guide links that slot to episode 1. Episode 2 follows on Monday 26 October, also at 21:00.
Both evening times are GMT, after the UK clocks go back on Sunday morning. The Sunday broadcast occupies a slot ending at 22:05; Monday's ends at 22:00. These are television slots, rather than the episodes' running times.
Six episodes on the ITVX listing
The ITVX programme page lists episodes 1 to 6. Start with the episode 1 link if you want to follow Beth and Tom's story from the beginning, rather than opening a later instalment's description.
Episode 1 is labelled 48 minutes. Its page also displays audio description, subtitles and British Sign Language. Check the episode page for the version you need before watching.
UK streaming access
ITV says you need to be in the UK to stream ITVX. A visible programme listing does not establish streaming rights in another country. Use the dated ITV guide for the linear broadcast and the linked ITVX episode page for on-demand viewing.
