In 2016, Tate competed as an "other" housemate on the seventeenth season of the British version of the Dutch reality television series Big Brother. He quickly saw himself as a strategist, admitting that he would get in the Big Brother house by any means necessary. The Others targeted specific people for a fake eviction, of which Tate was seen as the instigator. On Day 4, Alex Cannon and Jackson Blythe were fake evicted and moved to the Other house, with the public voting Tate and Ryan Ruckledge in to take their places. Tate gathered a handful of housemates over, saying that 80% of them were "snakes". Immediately, this caused a lot of conflict, and Marco Pierre White Jr. and Chelsea Singh decided to break out of the Big Brother house, only to return a few hours later. Tate was surprised by this outcome, saying to Big Brother that his plan had worked a little too well.
On Day 5, the Others were set a secret mission to convince the housemates in the Big Brother house to nominate one of their own for the first real eviction; this would be Laura Carter. However, after the Others had watched the previous night's events, and with Cannon and Blythe expressing their discontent at the drama caused, Tate was not optimistic about whether the task would be successful. In the Diary Room, he said to Big Brother that the Others were not unified in the task anymore, there was a distinct lack of support, and that Ruckledge was of no use to him. On Day 7, Tate was removed from the show for actions outside the house prior to the competition. The secret mission would still continue, but Ruckledge would fail to convince the housemates to nominate Carter, and on Day 9, he returned to the Other house.
It was later revealed that Tate had been removed due to a video, obtained by The Sun, of him allegedly “hitting a girl with a belt”. Tate would later make a statement on his Twitter account that the actions were consensual, the belt was actually made of felt, and that the Sun video was heavily edited to make him look bad. In a Facebook video, he claimed the real reason he was removed was because the programme's producers were “worried” about his “master plan", which was denied by Channel 5. Nonetheless, his picture on Big Brother's Bit on the Side was blacked out (although Emma Jensen's picture was grey; she was later ejected as well), and barely any mention was said of him in later episodes. Towards the end of the series, his picture in the Big Brother house was seen in certain shots.
