Summary: The 20 potential contestants arrive at a country manor house with a champagne reception, and are soon greeted by host Lisa, who informs them they are to enter the gruelling model boot camp. After completing an assault course and a catwalk challenge featuring clothing from the Ed Hardy range, as well as a brief individual meeting with the judges, 5 girls are eliminated when they don't find dog tags in boxes placed on their beds. The episode's photo challenge sees the remaining 15 girls put in three groups of five for an army inspired shoot with Huggy. At panel, the judges have praise for Hayley and Kasey, who both stand out in their pictures, as well as Lauren, who is rather bizarrely told by new judge Louis that she is 'the new Moulin Rouge'. Daisy is told she looks dead in the eyes, while Ashley disappoints when she states she is not happy with the way she has photographed. Mecia receives the first call out and is thrilled to be told she has booked a billboard campaign in the USA for Christian Audigier, after impressing on the catwalk. Ultimately, 2 more girls are eliminated; Nell because the judges are worried about her proportions and one dimensional look, and Rebecca over concern of her commitment to the competition. The 13 girls are finally ready to enter the Top Model house.

Summary: The girls excitedly move into the model house and are thrilled with their new abode. The following morning they are split into two teams for a very raucous fashion quiz, with the winners receiving designer watches. The week's challenge is to film an advert on the Millennium bridge wearing Elizabeth Emanuel bridal wear. The girls have to deliver some dialogue then kiss a male model. Kasey impresses and wins the challenge, while Mecia irritates the photographer by refusing to kiss the model, worried she will upset her boyfriend of four years. The girls return home to find high heels all over the living room and are delighted when J. Alexander (Miss J) appears from behind a curtain and informs the 'model bitches' it's time for them to learn how to walk. Daisy and Hayley prove to be amongst the strongest, while Lisa-Ann and Chloe's efforts are heavily derided and amusingly imitated by Miss J. The week's photoshoot challenge asks the girls to pose naked in a bath of water filled with mangos for the brand Simple Cosmetics. Sophie struggles, going into 'panic mode' once in the water, while Ashley is concerned how her body will look considering she has had two children. At elimination, the judges have praise for Daisy, Hayley, Mecia and Kasey, while Chloe is told her picture looks like soft porn. Mecia is also reprimanded for her performance at the week's challenge. Ultimately, Sophie and Lisa-Ann wind up in the bottom two; Sophie because of her poor performance at the photo-shoot and Lisa-Ann due to having a generally dismal week. Lisa-Ann is the first girl to be sent home from the model house.

Summary: Tensions rise in the model house when Annaliese tells the other girls to turn off the kitchen's extractor fan as she can smell mackerel and tuna in her bedroom at the other side of the house. Chloe answers back, accusing Annaliese of not washing her scrambled eggs pan with washing up liquid, which results in Annaliese angrily branding Chloe a wannabe porn star and lads mag model. The following day the girls excitedly receive their long awaited makeovers. Madeleine is very upset with her short, asymmetric ginger bob, and thinks she looks like a boy or "even a lesbian". Sophie and Ashley are also less than pleased with their short, edgier haircuts, although Kasey takes the removal of her blonde weave in her stride and seems happy with her short black bob. It is Viola, however, who impresses the salon's management the most, and she is chosen to model for their 50th anniversary advertising campaign. The week's challenge involves the girls performing a dance routine in groups of four at London's Movida nightclub. Mecia and Annaliese impress and they along with the winning group of four get to party the night away at the club, while the losers return home. At the week's photo challenge the girls are taken to an underground carpark and are shocked to be told they are to be paired up and will be snogging their partner. Sophie is disgusted that she will have to kiss Mecia, who has been sick the night before from drinking too much alcohol. Hayley, Daisy and Lauren perform confidently, while Chloe in particular struggles to feel comfortable on set. At panel, the judges have praise for Hayley, Daisy, Kasey and Jade. Madeliene is reprimanded for her attitude at the makeovers, but it is Ashley and Chloe who land in the bottom two for their weak performance at the photoshoot, with Chloe being told by photographer Nicky Johnston that her becoming a model is about as likely as him studying medicine at Harvard. In a shock twist, Lisa announces that both girls are to be given another chance and no-one is to be eliminated.

Summary: Returning home from judging panel, many of the girls, particularly Sophie and Daisy, are angry that nobody was eliminated. Chloe in particular is targeted, with some girls questioning her place in the competition. The following morning the girls are excited to meet 'rock royalty', Jo Wood, who challenges them to perform a short inspirational speech in front of a group of 12–16-year-olds. Jade impresses, talking candidly about her battle with anorexia, while Chloe particularly disappoints with her talk on her passion, make up. She also gets in trouble for lecturing against animal cruelty whilst wearing a leather jacket. Surprisingly to some of the other girls, Daisy wins the challenge. The next day the girls meet Johnny Vaughan at Capital FM, who interviews the girls in groups of three, with Lisa watching behind the scenes. Viola performs particularly badly, not saying one word throughout, while Annaliese impresses and wins the challenge, choosing to take Ashley on a shopping spree for the prize.
