A Channel 4's hit series which is known for its bold exploration of modern relationships, is gearing up for its third season and participants from south London who are open to “testing the waters of non-monogamy”.

The newest Open House: The Great Sex Experiment series will connect a cast of sexually open residents and offer them expert advice along the way.

The programme has drawn in around one million viewers per episode and offers couples the unique opportunity to explore open relationships in a luxurious retreat setting.

The show follows previously monogamous couples as they explore open sexual relationships for the first time, alongside a memorable cast of other sexually liberated residents at the retreat.

It airs on Fridays at 10pm, immediately following Gogglebox and has become a must-watch for those interested in the evolving dynamics of love and commitment.

As the show prepares for its new season, the producers are eager to find participants from south London.

They are looking for couples curious about exploring non-monogamy for the first time, as well as sexually liberated singles or individuals already in open relationships who want to join the retreat as residents.

The new season promises fresh twists, including a new open relationships expert and a stunning new location, continuing to push the boundaries of conventional relationship norms.

South Londoners interested in being part of this social experiment are encouraged to apply through the Channel 4 website.

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.”
