Adultery on ITV: when it’s on, the full cast, how many episodes and is it on Netflix?

Adultery, the new ITV drama series from Fool Me Once writer Danny Brocklehurst, started on ITV1 last night, Sunday 25 October, and episode 2 is on tonight at 9 pm. Dominic Cooper and Romola Garai play two married parents whose affair begins with a car accident, while their teenage children are already going out with each other. Here is when Adultery is on ITV, how many episodes there are and who is in the cast. And is Adultery on Netflix? No, but every episode is free on ITVX.

When is Adultery on ITV, and how many episodes are there?

Adultery started on ITV1 on Sunday 25 October 2026 and has six episodes, shown at 9 pm on Sundays and Mondays until Monday 9 November. All six are already streaming as a box set on ITVX.

In episode 2, tonight, ITVX’s episode guide says Tom and Beth are “forced together to help the kids”.

The dates are from TechRadar’s viewing guide, and the 2 November slot is already in the ITV TV guide. If you would rather not wait a fortnight for the ending, every episode is on ITVX now. ITV’s guidance warns of strong language from the start.

Is Adultery on Netflix, and where can you watch it?

No, Adultery is not on Netflix. You can watch it on ITV1 at 9 pm on Sundays and Mondays and stream all six episodes free on ITVX, or on STV and STV Player in Scotland.

TechRadar found no sign of it being shown in the US, Canada, Australia or New Zealand so far.

The Netflix title that turns up in searches, Adulterers, is a 2015 American film with no connection to the ITV series, according to Wikipedia.

The Netflix question makes sense, though. Brocklehurst has written four series for Netflix: Safe, The Stranger, Stay Close and Fool Me Once.

What is Adultery about?

Adultery is a six-part ITV drama series whose plot follows Beth Brookes and Tom Kirkman, two married parents drawn into an affair after Beth knocks Tom off his bike with her car. Their teenage children, Ollie and Jess, are already going out with each other.

Beth, played by Romola Garai, is a mother of two and a part-time zumba teacher who is struggling after the death of a close friend. Tom, played by Dominic Cooper, is a middle-class GP, the Independent’s review explains.

ITV says the story raises questions about class, grief and the effects of social media. Garai has been clear that this is not an affair born of a bad marriage. She told IBTimes that Beth “is being selfish because she is grieving”, and told Woman & Home it grows out of dissatisfaction that builds over time.

ITV released the first Adultery trailer in June, Televisual reported, when the drama was still billed for “later this autumn”.

Where was Adultery filmed?

Adultery was filmed in and around Manchester and in Lancashire, including the town of Darwen and the nearby village of Hoddlesden.

ITV said filming was under way in and around Manchester when it announced the cast. Crews were on Bank Street and Church Bank Street in Darwen at the start of November 2025, and Long Hey Lane in Hoddlesden was closed for filming in December, the Lancashire Evening Post reported.

Altrincham and Stockport were also used, along with Firwood Fold in Bolton, according to Rayo. Bolton is also listed as a location on the series’ Wikipedia page.

What are the reviews of Adultery like?

Reviews of Adultery are mixed. The Independent gave it three stars out of five and praised the chemistry between Romola Garai and Dominic Cooper, while some viewers questioned how realistic its A&E scenes were.

Viewers pointed out that Tom is seen almost straight away in a near-empty A&E department, and one asked why Tom has a southern accent when his brother’s is broad northern, Brit Brief reported. Others said they were going to binge the lot.

Will there be a second series of Adultery?

No second series of Adultery has been announced. ITV has billed it as a six-part drama, and the final episode is on ITV1 on Monday 9 November.
