Notes : As Josie walked during the nomination process, all nominations for her became invalid and any housemates who nominated her had to later choose a replacement nominee. John originally nominated Josie and Coolio for eviction, but post-Josie's exit replaced his nomination for Josie with Brian. : As new housemates, Michelle and Victor were exempt from nominations. Whilst nominating, housemates had to endure various individual tasks from past series of Big Brother in "Nostalgic Nominations". This week there was a double eviction, meaning the three or more housemates with the most nominations faced eviction. Had this been a single eviction, only Makosi and Nick would have faced the public vote. : During Day 13's nominations, housemates participated in "Nominations Roulette" - with the wheel determining what how a housemate must deliver their nominations to Big Brother. As with the previous week, this week was a double eviction, meaning the three or more housemates with the most nominations faced eviction. Had this been a single eviction, the same housemates would still have faced the public vote. Even though she was a new housemate, Vanessa was permitted to nominate and could be nominated so that she did not have a free pass to the final. : For the final two days, the public were voting for who they wanted to win rather than to evict.

Summary Daily summary Day 1 Tasks John was given a task by the Tree of Temptation to be "Mr. Nice Guy" to everyone in the house. Successfully convincing the majority of the house that he is behaving nicely would make him eligible for eviction, however, failure would result in immunity from the first eviction. Entrances After leaving the house as the winner of Big Brother 11, Josie reentered the house space later. She was joined by Preston, Chantelle, Nadia, Brian, Ulrika, Makosi, John, Coolio, Nikki, and Nick. Day 2 Tasks For the shopping task, Nikki was the sole participant in a task called "Who Is She?", an ode to one of her catchphrases. The first part of the task involved her identifying five female housemates from series past by touch only; each correct response earned her £50. She correctly guessed three housemates, earning £150 towards shopping. The second part of the task had Nikki identifying a female housemate (Lisa) from Big Brother 4 amongst a lineup of four people claiming the identity. Nikki correctly figured out the housemate, and won £500 extra, for a total of £650 towards shopping. Day 3 Tasks Nick was set a task by the Tree of Temptation to write down the names of the housemates who would face the public vote on pieces of paper and hide them in the House. Houseguest Darren was sent into the house later that day by the Tree to find the pieces of paper and announce to the House that Coolio and John were up for eviction. The housemates were asked to vote on whether or not John was behaving nicely. As the majority of the house thought John was being Mr. Nice Guy, he passed his task and thus was eligible to be nominated and evicted. Exits Josie voluntarily left the house through the garden door during nominations. As a result, nominations were temporarily suspended until the situation was contained. Any housemate who nominated her was required to nominate another housemate. Day 4 Tasks Nikki was given a task to complete within three hours. She was to interview all the housemates and using a typewriter, type up the results for her News of the World column. She successfully passed, and all the housemates won a party. Upon entering the Big Brother Bedsit, Michelle and Victor were given the task by Big Brother to play pranks on and reward the House, similar to what Michelle did when she entered the original Bedsit in Big Brother 5. Their first task was to send in a clown named Mr. Snuggles, who would then greatly bother a certain housemate of their choice. They chose Nikki. Exits John was the first person to be evicted from the House, with 50.6% of the vote to evict over Coolio; with only a little more than 1% separating the two, this was the second closest ever margin in Big Brother history. Entrances Victor and Michelle entered the Big Brother Bedsit, where they would stay for the next few days wreaking havoc on the House, unbeknownst to the other housemates. Day 5 Tasks Victor and Michelle, who were still in the Bedsit, were given another task by Big Brother. They were to give one housemate of their choice a slave for one hour. They chose Nadia, whose slave was Big Brother 9s Stuart. Later that day, Big Brother asked them to give two housemates a private party. They chose Brian and Nick. The housemates played a party game, which was watched by Victor and Michelle in the Bedsit. Each housemate was given a photo of one of their fellow housemates Exits Coolio left the Big Brother House after it was mutually decided between him and Big Brother that it would be best for him to leave, due to an ongoing verbal spat between him and Nadia. Though technically an ejection, it was considered a voluntary exit on the series. Day 6 Tasks The housemates bar Ulrika were given papier-mâché big head caricatures of themselves as part of today's Big Heads task. They were then given the challenge of staying in them for as close to one hour as possible, with the housemate closest to sixty minutes declared the winner. Ulrika was also given the secret task of predicting who would remove their big head off first, who would win the challenge, who would moan the most. She chose Nadia, Brian, and Nikki respectively. She correctly guessed Nadia would remove her head off first, and thus won treats for the House. Preston was the winner of this task (removing his head at 1 hour 1 minute 55 seconds), and won a special "prize" in the form of two new housemates: Michelle and Victor. Entrances Michelle and Victor entered the main house in the afternoon. Day 7 Tasks The housemates (bar Michelle and Victor, who entered the house the previous day) took part in their second round of nominations. However, as Big Brother was feeling nostalgic, each housemate was required to complete a task from a previous series whilst they nominated. The housemates were subject to the following tasks:
