Series chronology

This series was the first celebrity edition to launch under the new three-year contract that was announced in March 2015 which guaranteed the show remained on Channel 5 until 2018.

With sixteen celebrities, this series had the most housemates since the show began in 2001. However this is now held by Celebrity Big Brother 19 with eighteen. With three voluntary exits from Angie Bowie, David Gest and Jonathan Cheban, this series equalled the record with series 5 in 2007, which also had three housemates walk from the house. On 5 February 2016, the series was won by Scotty T, with Stephanie Davis finishing as runner-up.

Production

Sponsorship

Celebrity Big Brother 17 had no sponsorship, making it the first series of either Big Brother and Celebrity Big Brother not to have a sponsor since Celebrity Big Brother 1 in 2001.

House

A Channel 5 producer teased: "The famous house has undergone a major costume change, and housemates will be transported to a striking and theatrical setting which echoes the vaudeville theatres of a bygone era. The BB garden has been transformed into a Whitechapel style foggy street scene with a Victorian pub snug which will provide a hidden corner for sharing secrets and backstage backstabbing." Pictures of the new house were revealed on 18 December.

The House remains structurally similar to the previous series, however the kitchen and living area have swapped positions. What's more, the House has an old-age feel, with a Victorian pub-style kitchen area and theatre curtains down the staircase.

Summary

Day 1	Entrances	Gemma, John, Danniella, Christopher, Tiffany, Darren, Megan, Winston, David, Scotty T, Kristina, Jonathan, Angie, Stephanie, Jeremy, and Nancy entered the house.
	Twists	Upon entering the house, all the furniture had been boxed up with the housemates only having crates to sit on. After the first eight housemates entered, Big Brother asked the most decisive housemate to come forward and decide which two housemates should spend the first time in "The Box" without their possessions or luxuries. John volunteered himself and Darren to enter "The Box". Furthermore, John and Darren then had to decide which three of the remaining six housemates shouldn't have their suitcases delivered. They chose Christopher, Danniella and Winston. Following the arrival of the other eight housemates, John and Darren were given one last dilemma, a luxury food delivery for themselves or the kitchen to be unlocked for the remaining housemates outside "The Box". They chose to unlock the kitchen. Later that night, Danniella was given the option to send one of her fellow housemates to "The Box" in exchange for the bedroom being unlocked. She chose to send herself to "The Box".
Day 2	Tasks	Housemates were asked to rank themselves from most to least annoying, where they chose Jeremy, Scotty T and Stephanie to be most annoying. Those three were then told they would be responsible for unlocking the rest of the house and for getting Danniella, Darren and John out of "The Box". They were given their own box of 1,500 keys and would have to find the one which would unlock their box which represented an area of the house. They all successfully unlocked the remaining areas of the house and "The Box".
	Nominations	Following their task, Jeremy, Scotty T and Stephanie were called to the Diary Room and told that they would be solely responsible for nominations this week and had to each choose a housemate who would definitely face the first eviction. Jeremy chose Nancy, Scotty T chose Winston, whilst Stephanie chose Kristina.
Day 3	Tasks	Housemates were split into two teams with each team's captain reading out a series of facts. Their team then had to decide which housemate from the opposite side matched each fact.
	Punishments	Winston was given a warning about his behaviour towards the women in the house.
Day 4	Twists	Kristina was told she had received the most public votes so is safe from eviction. It was then announced that the housemates would decide between Nancy and Winston whom to evict.
	Exits	Winston was evicted from the house, receiving 13 of 14 votes to evict.
Day 5	Tasks	David was asked to produce a talent show, choosing Jonathan, Nancy and Tiffany as the judges, Angie as the host, and the remaining housemates as the acts. At the end of the show, the judges voted Stephanie as the winner.
Day 6	Tasks	The housemates were asked to line up in front of a row of podiums containing presents and were told that their present could be ejected from its podium at any time over many hours. Each person that caught their flying present would receive what was inside. They were unaware that Jonathan had already secretly chosen who would get what present. During the task, Tiffany won immunity from the next eviction, Nancy won incarceration and John was told he would have to make his next nominations face-to-face.
Day 7	Exits	Jonathan walked from the house.
	Nominations	The housemates nominated for the first time. Angie, Gemma, Jeremy, Nancy and Stephanie received the most nominations and faced the public vote.
Day 8	Tasks	For the housemates' first shopping task they were split into puppets and puppeteers. Each 'Puppeteer' was responsible for a 'puppet' and they had to do a variety of challenges. Puppets were only permitted to eat food provided to them and had their beds replaced with boxes.
Day 9	Tasks	The puppet task continued. However, at the end of the task it was revealed they had failed. Big Brother then gave a lifeline giving the opportunity for either the puppeteers or the puppets to have a luxury shopping budget based on who pressed a button the quickest. The puppets were faster and therefore won the luxury budget.
Day 10	Punishments	Megan was issued a formal warning for her aggressive behaviour in an argument the previous night. Tiffany was issued a warning for her aggressive behaviour used in an argument the previous night.
	Tasks	Housemates competed in a Lip Sync Battle challenge. Danniella, Kristina, David and Scotty T were the judges of the task, choosing winners from each pair's battle. The battles were Angie vs Nancy, Christopher vs John, Darren vs Tiffany, Gemma vs Megan and Jeremy vs Stephanie.
Day 11	Tasks	Housemates were split into two teams and had to try and work out which housemate the other group was describing by asking questions related to personality traits.
	Exits	Nancy was evicted from the house, receiving the fewest votes to save.
	Nominations	After surviving eviction, Angie, Gemma, Jeremy and Stephanie each had to give a killer nomination. They nominated Kristina, John, Tiffany and Danniella, respectively.
Day 12	Tasks	Housemates were split into two teams and given a task to balance a pair of scales with gunge. They were told that on each team there was a saboteur trying to make them fail. However, they were all told to be saboteurs. They successfully sabotaged the task and won a party. As Christopher and Gemma were identified as saboteurs they were not allowed to attend.
Day 13	Punishments	Stephanie was given a warning for threatening to punch Gemma the previous night.
	Tasks	Tiffany was given a secret task to spread rumours about her fellow housemates. She passed and won a pampering session, which she chose to share with Angie.
	Exits	David walked from the house on medical grounds.
Day 14	Tasks	The housemates were paired up for a dance competition with Kristina acting as judge. The pairs were chosen by Kristina; Christopher and Gemma, Danniella and Darren, Jeremy and Stephanie, John and Tiffany, and Megan and Scotty T. Kristina chose Jeremy and Stephanie as the winners.
Day 15	Exits	Angie walked from the house. Kristina was evicted from the house, receiving the fewest votes to save.
	Nominations	For this round of nominations, the housemates were required to give nominations face-to-face. They were unaware that receiving one single nomination would mean they'd automatically face eviction. Danniella, Gemma, John, Jeremy, Megan, Stephanie and Tiffany all received one or more nominations and faced the public vote.
Day 16	Tasks	For the second shopping task the housemates had to "Just Go Along With It" to a number of random events that would happen in the house. This included exercise first thing in the morning, Christopher and Tiffany getting up close to jungle animals, and Jeremy babysitting twin dolls.
Day 17	Tasks	The housemates continued with their shopping task. This included Gemma and John being chosen by the public to go to jail, Darren and Scotty T attempting to get ducks into their pen, and housemates having to impersonate each other. At the end of the task Big Brother told housemates they'd passed the task.
Day 18	Exits	Megan was evicted from the house, receiving the fewest votes to save.
	Twists	Big Brother announced that there would be no nominations this week; instead all housemates would automatically face eviction unless they earn immunity. Gemma was the first housemate to win immunity during the first live challenge in "The Forgotten Theatre".
Day 19	Twists	For the second chance to win immunity, the housemates were all gathered to answer questions honestly about their fellow housemates. Stephanie became the second housemate to win immunity.
Day 20	Twists	Darren was the third and final housemate to win immunity from eviction having identified the most gruesome cocktails. This meant the remaining housemates; Christopher, Danniella, Jeremy, John, Scotty T and Tiffany would face the next eviction. At the end of the tasks, immune housemates were required to ban three housemates from being invited to the masquerade ball in "The Forgotten Theatre". Gemma chose to ban Christopher, Stephanie chose Tiffany, and Darren chose Danniella respectively.
Day 21	Tasks	John was given a secret task to earn compliments from each of his fellow housemates. However, unbeknownst to him, all the other housemates were on a secret mission of their own to sabotage his task by insulting him instead. The housemates passed the task and earned a coffee machine for the following day.
Day 22	Exits	Christopher was evicted from the house, receiving the fewest votes to save.
	Twists	Gillian McKeith entered the house as a guest and was given the task to detox the housemates. She selected Stephanie, Scotty T, John and Tiffany as the housemates whom she believed to be the "most toxic".
Day 23	Twists	After further observations and inspections in the detox process, Gillian reassessed the group and chose Stephanie, Tiffany, Jeremy and Darren as the new "most toxic" housemates.
	Nominations	Only the four "pure" housemates; Danniella, Gemma, John and Scotty T were able to give nominations. Jeremy, Stephanie and Tiffany received the most nominations and faced the public vote.
Day 24	Punishments	Stephanie was given a warning for her behaviour during an argument the previous night.
	Tasks	For the housemate's next shopping task, multiples phones were installed into the house which could ring at any time. The housemates were told that their friends and family would be on the other end of the phone and to pass the task they must identify who was on the other end by asking questions with "yes" or "no" answers. Once the housemates correctly identified who they were speaking to, that housemate was allowed to speak to their loved one. However, the housemates were only given a certain amount of talk time, which if they used more than the amount given, they'd fail the task.
Day 25	Tasks	The shopping task continued. As housemates finished with some talk-time remaining, they passed the task and won a luxury shopping budget.
	Exits	Jeremy was evicted from the house, receiving the fewest votes to save.
Day 26	Tasks	The housemates were bound together with locks and chains until further notice. To escape the chains, housemates must correctly guess who received the most and fewest votes in a series of public polls. At the end of the task, Danniella and Tiffany were the only housemates who failed to unlock themselves and missed out on the reward.
	Rewards	With all housemates except Stephanie discussing nominations, instead of punishments, Stephanie was given a reward. Stephanie was then asked to deliver a killer nomination. She chose Danniella, meaning she'd face the next eviction.
Day 27	Tasks	For Gemma's birthday, all other housemates were set a secret mission to sabotage her birthday in order to win her the "best birthday ever".
	Punishments	As Stephanie discussed nominations, Big Brother turned off all hot water and electrical appliances.
Day 28	Nominations	The housemates all nominated for the final time. Gemma and Stephanie received the most nominations and faced the public vote with Danniella.
	Tasks	Stephanie was asked to assign her housemates to a list of mini-task, where each would take part as quickly as possible. In order to pass the task, all seven housemates must complete their tasks in fifteen minutes or less. As Gemma refused to take part in her task, housemates failed.
Day 29	Exits	Gemma was evicted from the house, receiving the fewest votes to save.
Day 32	Exits	John left the house in sixth place, Danniella left the house in fifth place. Tiffany left the house in fourth place and Darren left the house in third place. It was then revealed that Scotty T was the winner, leaving Stephanie as the runner-up.

Notes

• ^Note 1 : As a consequence of a task Jeremy, Scotty T and Stephanie were solely responsible for deciding who should face the first eviction. On Day 4, it was revealed that Kristina received the most votes to save. Following this, Nancy and Winston were subject to a house vote on who should be evicted. Nancy received just one vote to evict (from Jeremy), whilst Winston received the remaining thirteen votes to evict.
• ^Note 2 : On Day 6, during a task, Tiffany won immunity from the next round of nominations and John was told he'd have to make his next nominations face-to-face.
• ^Note 3 : On Day 11, eviction survivors Angie, Gemma, Jeremy and Stephanie had to give one killer nomination each.
• ^Note 4 : These nominations were face-to-face. Everyone who received at least one nomination faced eviction.
• ^Note 5 : Big Brother announced that there would be no nominations this week, instead all housemates would automatically face eviction unless they earn immunity. Gemma, Stephanie and Darren won immunity and the remaining housemates faced the public vote.
• ^Note 6 : Only the "pure" housemates chosen by Gillian McKeith were required to give nominations.
• ^Note 7 : On Day 26, Stephanie was allowed to make a killer nomination due to all other housemates breaking rules regarding discussing nominations.
• ^Note 8 : This week the public were voting to win, rather than to save. The voting figures reflect the overall share of the final vote, and do not take into account the vote freezes between each position; due to rounding, the percentages do not perfectly add up to 100%. Scotty won with 57.75% of the vote to win over Stephanie.
