Derek Evans is a social worker, played by Simon Lowe. In March 2007, he visits Bert Atkinson (Dave Hill) and his grandson Jay Brown (Jamie Borthwick), when Bert is trying to get a residency order for Jay to live with him permanently. Jay charms Derek, offering him a cup of tea and talking to him politely, impressing him. In January 2008, Derek visits Tanya Branning (Jo Joyner) and her sister Rainie Cross (Tanya Franks). In October that year, he attempts to sort out Jay's foster care problems when Billy Mitchell (Perry Fenwick) offers to care for him, as Jay does not want Dawn Swann (Kara Tointon) to be his foster mother. Derek inspects the flat above The Queen Victoria public house, and allows Jay to stay with Billy, despite Roxy Mitchell's (Rita Simons) messiness. In July 2009, he visits Denise Wicks (Diane Parish) after Jordan Johnson's (Michael-Joel David Stuart) mother Trina (Sharon Duncan Brewster) reports her to the police, claiming that Denise has been abusing Jordan. In June 2010, he visits Phil Mitchell (Steve McFadden) to assess his family situation involving his children Louise (Brittany Papple) and Ben (Charlie Jones), who has assaulted Jordan. The following month he visits Phil and his mother Peggy Mitchell (Barbara Windsor) to say that Louise's mother Lisa Fowler (Lucy Benjamin) has made an application to see her daughter. Derek explains that the final decision is not up to Phil and Peggy says that Derek is a typical social worker – an interfering, home-wrecking busybody. Derek responds sarcastically and leaves. When Peggy returns Louise to Lisa, they contact Derek again, and when he arrives, Phil steals his bag to get Lisa's address.

In April 2015, Derek visits Kat (Jessie Wallace) and Alfie Moon (Shane Richie) after Kat attempts suicide. Kat refuses to tell Derek why she did it but assures him that it will not happen again. Alfie then tells Derek that he felt he had let Kat down but he would help her get better. Derek is satisfied with this and leaves. In July, he visits Shirley Carter (Linda Henry) and Buster Briggs (Karl Howman) to discuss them gaining custody of their granddaughter, Jade Green (Amaya Edward). Buster informs Derek of his criminal record and Derek tells Shirley that single people can adopt children as well, prompting Shirley to nearly split up with Buster. In May 2016, Derek visits Billy and his partner Honey Mitchell (Emma Barton) after Jay returns to live with them after being convicted of a child sex offence to assess Jay being around their children, Janet (Grace) and Will Mitchell (Freddie Phillips). Billy and Honey insist Jay is innocent but Derek informs them that Jay's contact with their children must be supervised. Derek returns in August after Honey reports Jay to the police for possession of drugs which he had been dealing, to reassess their living arrangements. Derek tells Honey that he is concerned about her children's welfare due to the presence of the drugs and implies that Jay might be a danger to Janet and William, causing Jay to decide to move out of the flat. After Jay's home assessment discovers he is living with an underage Louise (now played by Tilly Keeper) at Phil's house, Derek visits Sharon Mitchell (Letitia Dean) and despite Sharon insisting that she and Phil trust Jay, Derek tells her if Jay does not move out, Louise may have to be taken into care as her needs come first.

Marco Bianco, played by Bart Ruspoli, is the interior designer who redesigns the flat above The Queen Victoria pub for Peggy Mitchell (Barbara Windsor). He works on the design to renovate the pub itself, after Pat Evans (Pam St. Clement) found a flea on the bar, though the regulars think the pub looks the same, and Peggy berates him for it.

Peggy then gets him to do some work for Stella Crawford (Sophie Thompson) and Phil Mitchell's (Steve McFadden) wedding reception. At one stage Marco breaks down crying to Peggy, after his boyfriend left him. Marco also helps Patrick Trueman (Rudolph Walker) mend a fan of his wife Yolande's (Angela Wynter) that Patrick broke by tripping up.

Anya Covalenco (Ukrainian: Аня Коваленко), played by Olga Fedori, is a Ukrainian illegal immigrant, a pole dancer who abandons her month-old baby, Tomas, in a church in Kent for vicar Mary Lavender (Regina Freedman) to look after. Dot Branning (June Brown) later finds the baby, and knowing Reverend Lavender is on holiday, takes Tomas back to Walford, leaving a note in the church with her address on it.

Dot's husband Jim (John Bardon) goes to a pole dancing club, finding a flyer for it with Tomas, to track Anya down, but is told she no longer works there by a hostess he speaks to. As Jim travels back to Walford, Anya arrives at Dot and Jim's house. After shouting at Dot for interfering, Dot offers her a place to stay, and she accepts. Jim, however, does not agree with this, and reports Anya to the immigration authorities. Immigration officers arrive and Jim tells Dot what he has done. Dot takes Anya and Tomas out of the house and hides them in the back of her car. Dot returns to the house and tells immigration that there is nobody there and it must have been a hoax. Dot and Jim then take Anya and Tomas to a church, believing it to be a sanctuary where they will be safe. The immigration officers follow them to the church, where Dot says Anya and Tomas will be safe in a room at the back of the church and could live there. Dot confronts the officers, Paul Jenkins (Simon Quarterman) and Warren Rice (Ewan Bailey) telling them it is a sanctuary and they cannot go through. Rice tells Dot she is wrong about this. Anya eventually decides to give herself up, but tells Jim to take care of Tomas as she now trusts them.
