Open House: The Great Sex Experiment | Preview (Channel 4)

The boundary pushing social experiment will return with a new open relationships expert, a new luxury location and some exciting new format twists.

Open House will continue to provoke conversations about whether monogamy is an outdated concept in modern relationships, following previously monogamous couples as they experiment in open sexual relationships for the very first time the unforgettable cast of sexually liberated Open House retreat residents.

In the first episode of the new series, Married couple Chloe and Paul from Liverpool are childhood sweethearts who've never had sex with anyone except each other.

Now they want to see if an open relationship can allow Chloe to explore whether she might also be attracted to women. Mark and Tanith from Yorkshire want to find out if having sex with other people can help build trust, which has been under threat due to Mark's past cheating.

The first series, which aired in 2022, remains Channel 4’s biggest new unscripted 10pm series launch since 2017 and the second series was up 13% share of young audiences (16-34s) in the same slot. 

Commissioning Editor Tim Hancock said, “Reflecting the growing trend of non-monogamy in an authentic, aspirational and sometimes shockingly frank way, Open House is the kind of show that can only sit on Channel 4. Its continued success has been due to an alchemy of excellent casting and high-quality storytelling, and I can’t wait to discover who’s coming to the house this time around.”

Firecracker’s Chief Creative Officer, Jes Wilkins, who devised the series said: “Open House is the perfect embodiment of the mischievous purpose which has always characterised Firecracker’s best work for Channel 4. For such a bold format to be greenlit for a third series in the current commissioning environment is a towering achievement for everyone involved at both Firecracker and Channel 4.”

Open House: The Great Sex Experiment returns Friday 9th May at 10pm on Channel 4.
