Big Brother UK 2025 kicked off on ITV2 this Sunday, September 28, throwing 12 new contestants into Britain’s most-watched house.
Hosts AJ Odudu and Will Best introduced a wild mix of personalities, from an 18-year-old cleaner to a 56-year-old PR veteran, all ready to live, laugh, and maybe lose their minds on camera. But the show wasted no time stirring chaos; someone’s already set to be evicted within the first 24 hours.
Inside the house, contestants battle through challenges, form shaky alliances, and face public votes that can flip everything overnight. Big Brother UK fans get the final say on who stays and who gets the boot, keeping everyone, inside and out, on edge.
This season also marks 25 years since the show first locked strangers together under 24/7 surveillance. The show will have a seven-week run packed with unexpected twists, dramatic showdowns, and plenty of “did-that-just-happen” moments, all in the name of chasing one big cash prize.
Big Brother UK 2025 cast explored
Twelve contestants entered the house representing different corners of the United Kingdom. Gani, a 39-year-old pizza shop manager from South London, brings life experience to the competition. Cameron, 22, works as a farmer in Taunton, offering a rural perspective.
Nancy, a 22-year-old recent graduate from Glasgow, joins the younger demographic. Caroline, 56, represents the oldest housemate as a PR specialist from Canvey Island. Zelah, 25, works as a personal trainer in South London, while Teja, 18, arrives as the youngest contestant working as a cleaner in Bristol.
Emily manages political events at 25 and hails from Northampton. Marcus, 22, has a mechanical engineering background and is from Manchester. Tate, 27, runs his own business in Falkirk. Elsa creates content at 21 and is from Essex. Sam teaches Zumba at 27 in Skipton. Jenny, 20, practices makeup artistry in Derry.
The premiere episode wasted no time introducing dramatic tension. After initial introductions, the hosts announced an elimination threat affecting the group. Five housemates received the highest viewer votes, placing them at risk: Emily, Sam, Nancy, Cameron, and Caroline. This early voting created instant pressure and uncertainty among the new arrivals.
Big Brother later revealed Caroline and Cameron were safe from elimination. Emily, Sam, and Nancy received instructions to enter the exit room, where they learned only two would return to the house. The first evictee's identity remains unknown until Monday, September 29's episode. This cliffhanger keeps audiences engaged while contestants process the reality of their vulnerable positions.
In addition to the main show, the 25th anniversary season features extra programs. Big Brother: Late & Live airs exclusively on ITVX and offers behind-the-scenes insight and discussion. Celebrity visitors will talk about house happenings over the season. JoJo Siwa, Chloe Burrows, Oti Mabuse, Danny Beard, Angellica Bell, David Potts, and Harriet Rose have all confirmed their presence.
Odudu and Best will moderate these talks, promoting arguments and fostering polite interaction among visitors with opposing viewpoints.
What does this season promise?
Big Brother UK Host Will Best teased significant surprises throughout the seven-week competition. He noted the season remains shorter than the longest-ever 13-week run, ensuring sustained momentum.
The mysterious rolling eyeballs featured in promotional materials will play crucial roles during the opening week. Best confirmed these elements integrate directly into early gameplay mechanics. UK viewers of Big Brother UK can watch via ITV and ITVX with free accounts. International audiences require VPN services to access episodes outside British territories.
The combination of diverse casting, immediate drama, and promised twists positions this anniversary season as potentially one of the show's most memorable runs.
Big Brother UK 2025 airs Sundays on ITV1 and streams nightly on ITV2 and ITVX.
