Big Brother 2018, also known as Big Brother 19, is the nineteenth series of Big Brother, and the final series to air on Channel 5. The series launched four days after the final of Celebrity Big Brother 22 on 14 September 2018 and lasted for 53 days with the final episode airing on 5 November 2018. The series is the eighth regular and twenty-third series of Big Brother to air on Channel 5 since 2011; it was also the final series of Big Brother in the three-year contract that was announced on 19 March 2015, which guaranteed that the show would air on Channel 5 until 2018.

On 14 September 2018, it was confirmed that this series would be the final series to air on Channel 5.

On 5 November 2018, Cameron Cole was announced as the winner of the series, beating Akeem Griffiths who finished as runner-up. At 19 years old, Cole is the youngest winner of Big Brother in the UK series' eighteen-year history. Much like Ultimate Big Brother, the final Channel 4 series, the series ended with the words "Big Brother will get back to you".

Following Channel 5's decision in 2018 not to renew their contract with Endemol/Initial TV to show the series, ITV2 bought the rights to Big Brother in the United Kingdom, where it was broadcast from 8 October 2023, currently hosted by AJ Odudu and Will Best.

This marked the last regular appearance of Emma Willis as presenter after six series.

Format On several occasions in the run-up to Celebrity Big Brother 22, various news reports and Big Brother alumni hinted at the series going back to its roots, with less producer manipulation and a focus on the show as a social experiment.

The shows' producers also met with several fansites to discuss the direction of the show, with it being heavily reported that the show will bring back weekly shopping tasks and a consistent nominations format.

Housemates In an interview with fansite "BBSpy", creative director Paul Osborne stated that the team were actively trying to find "totally unknown" housemates for the series. In the past, some housemates had previously appeared on reality shows such as The Valleys, Ibiza Weekender and Ex on the Beach.

On 10 September 2018, during the final of Celebrity Big Brother 22, a trailer was released showing close-ups of each of the fourteen housemates with their occupation, age and home town, and the public were granted the power to give one of them an early advantage in the series by voting in a poll.

Notes

: In the first week, there were no nominations. Instead, housemates were tasked with collecting "Big Coins". The three housemates with the fewest faced the public vote. : This housemate was nominated by the public, as they received the fewest votes in an app poll. : Week 2 introduced the Gamechanger. Each week, six Housemates participated in the Gamechanger Competition for the Gamechanger Power - the ability to save a nominee from eviction. The nominees and the richest housemate would be guaranteed to play, with the remaining slots being allocated by the richest housemate to the housemates of their choice. : As new housemates, Hussain and Isabella were exempt from the nomination process. Tomasz bought immunity at the weekly auction but could still nominate. : Hussain won the "Absolute Power Nomination" in a secret auction, and was, therefore, able to anonymously choose a housemate to face eviction. He nominated Lewis F, who was also ineligible to play in the Gamechanger and could not be saved by the gamechanger. : This week was a double eviction. Following the first eviction on Day 36, the remaining Housemates played a week's worth of Big Brother — including nominations (though housemates were not required to give a reason), the Gamechanger competition and ceremony during the remainder of the live eviction show, culminating in a second eviction for the night. Cameron, as the richest housemate, had immunity for this second eviction, as well as the power to evict either of the Final nominees (Akeem or Isabella) from the house. : This week was positive nominations. As such, housemates were nominating who they wanted to stay rather than leave. The housemates with the fewest nominations would be nominated. : Week 6 was the final week in which the Gamechanger Power was in play. Additionally, the Final Gamechanger had the power to save two nominees, as opposed to one. : There were no nominations in Week 7. Instead, the phone lines opened for the public to vote for the winner. The phone lines froze on Day 50, and the two housemates with the fewest votes were evicted.

Weekly summary The main events in the Big Brother 19 house are summarised in the table below. A typical week begins with nominations, followed by the shopping task, and then the eviction of a Housemate during the live Friday episode. Evictions, tasks, and other events for a particular week are noted in order of sequence. Week 1 Entrances On Day 1, Cian, Anamélia, Lewis F, Kenaley, Tomasz, Cameron, Sîan, Ellis, Isaac, Brooke, Akeem, Kay, Zoe and Lewis G entered the house. Twists On Day 1, it was revealed that nominations will not take place for the first week. Instead, housemates would collect "Big Coins", and the three housemates with the least coins would face the public vote. Sîan received 100 coins from a Big Brother poll in the week leading-up to the launch. The same night, 900 coins were dropped from the ceiling for the housemates to collect. It was also revealed during the launch that the housemate who sleeps in "Bed 13" would receive a special advantage; the chance to switch BigCoin totals with another housemate of her choice at the end of the task. Zoe won this power, and swapped coin totals with Lewis G. Exits On Day 2, Ellis was removed from the house after old social media posts from 2014 came to light which producers of the show deemed to be "offensive and unacceptable that references the 9/11 terror attacks". On Day 8, Anamélia became the first housemate to be evicted. Week 2 Nominations On Day 10, housemates nominated for the first time. Lewis F and Lewis G received the most nominations this week. Unaware to the housemates, the public were voting to save. Issac being the one with fewest votes to save was nominated as well. Tasks On Day 12, Kenaley won this week's Game Changer competition and saved Isaac from eviction. This week's shopping task involved the housemates counting chickens - both real and fake - released in the house over two days. If housemates came within a margin of error of 35 from the actual total they would win a luxury shopping budget. Housemates failed this task. Punishments On Day 9, Lewis G received a verbal warning for "cross-contaminating" food despite alarm being raised by Cameron and Akeem, and a formal warning for invading the personal space of Lewis F. On Day 10, Isaac received a verbal warning for saying that he would "smack" Lewis G on the outside world. On Day 13, as punishment for discussing nominations, Big Brother deducted 100 Big Coins from Lewis F's total. Exits On Day 15, Lewis G became the second housemate to be evicted.Week 3 Nominations On Day 17, housemates nominated for the second time. Akeem, Issac, and Kay received the most nominations. Brooke and Kenaley received the fewest votes from the public. Tasks On Day 19, the nominated housemates, and Cian and Cameron took part in the Game changer task, which was a game of true or false based on their party from the previous night. Kenaley won this task and chose to save herself from eviction. On Day 20, this week's shopping task began involving the housemates going on a 'trip' to China and completing a variety of tasks throughout the trip without surpassing the undisclosed number of fails allowed. Tasks involved understanding Mandarin, performing Chinese dances and surviving the flight to and from China. Housemates were successful in this task. Exits In the early hours of Day 19, Kay decided to voluntarily leave the house.
