Hallows worked as Head of Drama Production at Mersey TV.[1] Hallows was also producer of Grange Hill in 2003.
Hallows began work on Hollyoaks in 1995 and joined the show from its ninth episode.[2] Hallows served as the show's series producer until 2005, when she served as an executive producer, alongside programme creator Phil Redmond. Hallows was responsible for Hollyoaks: Breaking Boundaries, which saw the rape of long-term character Luke Morgan, which was the first time male rape was tackled in a soap. Hallows worked closely with advisers from rape-related support groups to help her make the storyline realistic.[3] Hallows was responsible for killing off Lewis Richardson in her time on the show, which occurred in Hollyoaks: Movin' On.[2] Hallows also worked on Hollyoaks: After Hours.[4] Hallows was responsible for the increase in late-night specials, which proved popular with viewers, so she decided to respond to requests for more.[4] Hallows also worked on Hollyoaks: On the Pull and Hollyoaks: Let Loose. David Hanson later joined the show as a series producer in late 2005, and both Hallows and Redmond departed a few episodes afterward. While on the show, Hollyoaks received a nomination for the Royal Television Society Award, which Hallows felt was rewarding.[5]
