The first time Gray Atkins saw Chantelle was when he drove past and splashed with a puddle.
Chantelle arrives in Walford as a hairdresser, who Kim Fox contacts to work as a new hairdresser in her and her sister Denise Fox's new unisex salon. Chantelle does not actually know that she is auditioning for a job as she presumes that she was cutting someone's hair and that was all. Kim later offers Chantelle the job; she refuses at first, but then later agrees to help at the salon, but only part-time. During celebratory drinks in The Queen Victoria public house, Chantelle bumps into her father Mitch Baker, who she has not seen for a long time. Chantelle later meets her mother Karen Taylor and reconnects with her family. On the opening day of the salon, Chantelle gives a haircut to a man and he gives them £100. She crosses the man again in The Queen Vic and kisses him, and it is revealed that he is her husband Gray Atkins. With Gray's permission, Chantelle agrees to work at the salon and they plan on relocating to Walford with their children Mia and Mackenzie. Chantelle boasts about moving to 1 Albert Square, unaware that Kim once lived there with her estranged husband Vincent, which causes hostility between the two women. Chantelle and Kim resolve their differences, but their feud ignites again when they argue over attending to Rainie Branning.
Chantelle and Gray's perfect relationship attracts attention in Walford. Chantelle's friend Whitney Dean compliments her relationship with Gray and asks her for advice on her relationship to Callum "Halfway" Highway; Honey Mitchell also compliments the couple and Chantelle's family warm up to Gray. However, the relationship turns out to be the opposite as it is revealed that Gray abuses Chantelle, which is first seen when Gray becomes angry at Mitch for cheating at the Walford 10K run and accuses Chantelle of laughing at him. Gray apologies to Chantelle and she later forgives him. Chantelle's brother Keegan Baker stays with the couple and, after becoming inspired by someone from Gray's workplace, decides that he wants to leave school. This causes a fight between Mitch and Gray, and Gray abuses Chantelle in response to his anger.
Chantelle discovers she is pregnant and tells Gray. He reacts positively to the news and stops abusing her. However, she miscarries but decides not to tell Gray in fear of him abusing her.
