Note: the episodes are put as number of actual episodes + special episodes.
Series 1 (2005) The first series began in February 2005, with the opening theme being "
Montagues and Capulets". The viewer ratings climbed to almost 4 million viewers for the final episode on 4 May 2005. The winner of the first series was
Tim Campbell, (
Saira Khan finished as finalist) who had previously worked as a Senior Planner within the Marketing and Planning Department of
London Underground. After his victory he went on to become Project Director of Amstrad's new Health and Beauty division at the time, but left the company to pursue other interests the following year, starting up the
Bright Ideas Trust in 2008 which offers funding and support for young people wishing to start their own business. In August 2008, the American cable channel
CNBC began to present the first series on Monday nights, but it was aired in disparate time slots or not at all due to the network's abrupt shifting of their programme schedule in order to cover developments of the
2008 financial crisis, leading to the series not being broadcast in full. With CNBC deciding to focus their prime time schedule on financial news programming, the programme's rights were moved to
BBC America, where it started transmission on 5 May 2009.
Series 2 (2006) The second series began on 22 February 2006, with a spin-off programme introduced on
BBC Three to air alongside it called ''
The Apprentice: You're Fired!''. The second series finished with a record of 5.7 million viewers watching the final being won by
Michelle Dewberry. Dewberry briefly took up a post under Sugar following the series, but left in September 2006 after a series of personal problems.
Series 3 (2007) For the third series, 10,000 applications were received by the production staff, with a promise made to incorporate "tougher tasks and better people", after Sugar expressed concerns that the show was becoming similar in format to that of
Big Brother. Alongside this, the
BBC also revealed that the programme was being moved over to
BBC One and aimed at a more "mainstream audience", with the broadcaster subsequently moving ''The Apprentice: You're Fired!'' to
BBC Two as a direct result. The third series started on 28 March 2007 with viewing figures of 4.5 million, climbing throughout the run to a peak of 6.8 million people, all watching the final being won by
Simon Ambrose.
Series 4 (2008) Candidates applying for the fourth series were invited to do so through the programme's official website, leading to 20,000 applications being submitted for the series, and 16 of them making it through to take part in the show. Its first episode aired on 26 March 2008, with its debut attracting 6.4 million viewers. This climbed to around 8.9 million viewers for the final episode, with an additional 800,000 viewers tuning in for the episode's final 15 minutes, to catch
Lee McQueen winning the fourth series. Lee went on to initially work for Sugar's company AMSHOLD, where he phoned in sick on his first day.
Series 5 (2009) Prior to the start of filming for the series, Adam Freeman, one of the lucky sixteen that had made it onto the fifth series, was forced to pull out; it was stated that his reasons for doing so were due to "family matters". This meant that when the series began on 25 March 2009, viewers got to see fifteen candidates vying for the prize, with
Margaret Mountford announcing her decision to stand down as a participant of the show during its broadcast, officially confirming it on ''You're Fired''. The fifth series was won by
Yasmina Siadatan.
Series 6 (2010) Following Mountford's departure,
Karren Brady was officially revealed as her replacement on 30 August 2009, later revealing in a newspaper interview on 28 February 2010 that the contestants would no longer refer to Alan Sugar as "Sir Alan"', but instead must call him "Lord Sugar", following his elevation to the
House of Lords as a
life peer. Because of the
2010 general election being held in the United Kingdom, the BBC opted to delay the sixth series until after it had been held, as Alan Sugar had ties to the government at the time; although he stated his intention of maintaining his position in the show, the running of
The Apprentice during the general election could have been a "risk to impartiality". Advertising of the series commenced after it was held, throughout the Summer, with the opening episode eventually broadcast on 6 October 2010. This series was the first to feature a two-hour crossover special between the main programme and its spin-off, ''You're Fired'', a format that would be used in the series finals of both in subsequent years. The sixth series was won by Stella English, who was placed into Sugar's company
Viglen. In May 2011, she requested a new role after saying that she was just a "glorified PA", and retained this for a year before it was decided not to renew her contract. The decision drew considerable media attention, after she attempted to sue Sugar for wrongful dismissal in February 2012, only for the legal action to be ultimately unsuccessful.
Series 7 (2011) Applications for the seventh series began in April 2010. Between the applicants being processed, to the filming of the first task, Sugar announced that the prize had been changed, and that now participants of the show were competing for an investment from him of £250,000, with Sugar becoming their business partner, owning a 50% share, but also providing guidance and support from himself and a team of experts to help develop the winning candidate's plan. Those applying prior to this announcement, were not aware of the prize change until later on. The change was due to the issue involving English and that Sugar was finding it difficult to find roles for the winners. The sixteen candidates who eventually secured a place on the series were revealed on 3 May 2011, via the official website and in a press launch, with the opening episode aired a week later on 10 May. In a change to format, the final involved the Interviews that candidates undertook, though these included a scrutinising of the candidates' business plans as well. After winning the seventh series, Thomas Pellereau became Sugar's first business partner, whereupon he used his prize to launch a range of manicure products with assistance from Sugar, including a line of curved nail files – the S-file, the S-Buffer and the Emergency File, two curved nail clippers, the S-Clipper and S-Clipper mini and a curved foot exfoliator, and the S-Ped – which were made available with major retailers in the country. While Susan Ma failed to win the series, Sugar said that he liked her plan, later investing into her skincare company Tropic in 2012.
Series 8 (2012) The eighth series began on 21 March 2012, and was the last to use the format for the task layout as was used in the previous series. The eighth series was won by Ricky Martin, who used his prize to launch his joint venture recruitment company called Hyper Recruitment Solutions (HRS), on 23 October 2012, which was designed to deal with recruitment in the field of science. Ricky was subsequently invited back to appear on the tenth series as an interviewer.
Series 9 (2013) The ninth series began on 7 May 2013, and saw the format of the task layout reverted to its original approach prior to the seventh series, though with the final task amended to focus on the investment prize, in which the finalists of the process had to conduct a presentation of their business idea to a panel of experts, including branding, an advert, and answering any questions given about their proposal. The ninth series was won by Dr.
Leah Totton, who used her prize to open her first cosmetic skin clinic on 22 January 2014.
Series 10 (2014) Because of the
2014 FIFA World Cup and
2014 Commonwealth Games, the tenth series was postponed until mid-Autumn to avoid clashing with the live coverage of both sporting events. To commemorate the programme's tenth year, the series featured 20 candidates, with two of the tasks dedicated towards the items that had featured within them. The tenth series began on 14 October 2014, was won by
Mark Wright, who used his prize to start an SEO business called Climb Online. The series was the last to feature
Nick Hewer, who announced his decision to depart from the show during its broadcast, officially confirming it on the series finale, during the ''You're Hired'' half of the episode.
Series 11 (2015) Due to the
2015 General Election, the show was postponed until mid-Autumn, to avoid clashing with the political event due to Sugar's ties with it at the time. Because of Hewer's departure,
Claude Littner was confirmed as his replacement prior to the opening episode of the eleventh series on 14 October 2015, though he retained his role as one of the key interviewers of the Interviews stage. The production staff now focused on applicants who were older and more experienced in business, with the number of candidates taking part now increased to 18. The eleventh series was won by Joseph Valente, who used Lord Sugar's investment and assistance to help him expand his plumbing business, Impra-Gas. The pair worked together on developing the business model for two years, until Valente announced in early 2017 that he intended to go solo and would be assuming full control. Both men parted ways on good terms, with Valente thankful for the help and opportunity that he had received, while Sugar wished him the best of luck and that he would be following the company's progress.
Series 12 (2016) As before, the BBC postponed the twelfth series to mid-Autumn, so as to avoid clashing with live coverage of
Euro 2016, the
2016 UK EU membership referendum and the
2016 Rio Olympics that were to take place during the Summer. The twelfth series began on 6 October 2016, and was won by Alana Spencer, who used her investment to kickstart a nationwide bakery business called Ridiculously Rich.
Series 13 (2017) The thirteenth series of the show was broadcast in late Autumn 2017, maintaining the broadcast schedule set by the previous three series. The thirteenth series began on 4 October 2017, and was won by both James White and Sarah Lynn, making it the first time in the show's history where two finalists were joint winners. Each would go on to use their individual investment to set up their own business – White would use his to start up an IT recruitment firm called Right Time Recruitment, while Lynn would use her investment to start up an online personalised sweets gift service called Sweets in the city.
Series 14 (2018) Unlike the last three series of the programme, the fourteenth series, which took place in late Autumn 2018, reverted to involving 16 candidates vying for Sugar's investment offer, and included a number of subtle changes to keep the format fresh such as candidates being sent abroad for the first task. The fourteenth series began on 3 October 2018, and was won by
Sian Gabbidon, who used her investment to launch a luxury swimwear range.
Series 15 (2019) As with the previous series, the format for the fifteenth incorporated the new changes introduced, including the first task taking place abroad, the number of candidates taking part being at 16, and teams not being named until each consisted of a mix of women and men. The series began airing on 2 October 2019. The fifteenth series was won by
Carina Lepore, who used Sugar's investment to fund new stores for her "family-run" baking business across London.
Series 16 (2022) The sixteenth series was originally planned for filming to begin in spring 2020, but the onset of the
COVID-19 pandemic at that time forced the BBC to postpone production to a later date. In lieu of a new series for their Autumn broadcast schedule, the broadcaster opted to fill the space with a special compilation series of highlights from previous series. In May 2021, it was announced that filming for the sixteenth series would take place later in the year, with the new series intended for broadcast on 6 January 2022. The sixteenth series was won by Harpreet Kaur who used her prize to set up a dessert parlour she would rename Oh So Yum.
Series 17 (2023) The seventeenth series aired from 5 January 2023 to 23 March 2023, and this was the second consecutive series with only women present at the interviews stage, and the fourth consecutive series with two women in the final. Marnie Swindells won the seventeenth series.
Series 18 (2024) The eighteenth series aired from 1 February 2024 to 18 April 2024 on BBC One. It was originally scheduled to air in January 2024, but it was postponed to February 2024 to avoid the clash with the second series of the rival BBC reality show
The Traitors. The eighteenth series was won by Rachel Woolford.
Series 19 (2025) The nineteenth series began on 30 January 2025 which coincided with the show's 20th anniversary. The nineteenth series was won by Dean Franklin.
Series 20 (2026) The twentieth series aired on 29 January 2026. For the first time since series ten, and the second time overall, there were 20 candidates taking part in the series. ''
The Apprentice: You're Fired! was also reformatted as The Apprentice: Unfinished Business'', presented by
Angela Scanlon. On 16 April, the twentieth series was won by
Karishma Vijay. ==Filming==
