The actress will play Carol Barry, head of a troublemaking family set to cause chaos in the school when it opens for its first term in Scotland.
Carol is lone-parent to unruly kids – bad boy Barry and daughters Dynasty and Kacey played by Carl Au (Jersey Boys), Abby Mavers (Willy Russell’s Our Day Out) and newcomer Brogan Ellis.
The trio arrive at Waterloo Road as headmaster Michael Byrne’s (Alec Newman) newest recruits for his pupil referral unit.
Zoe Lucker says: “I’m delighted to join the cast of Waterloo Road and work with Shed and the BBC again. It’s a show I’ve always enjoyed and I’m thrilled to be part of the outrageous Barry family.
“Carol and her kids are going to ruffle plenty of feathers in Waterloo Road – you can’t trust them as far as you can throw them! They’re a family of great characters – you just wouldn’t want the Barrys in your neighbourhood!”
Cameron Roach, Head of Drama for Shed Productions & Executive Producer, Waterloo Road, says: “Zoe is a terrific addition to our ensemble cast, it is incredibly exciting to be working with her again after working together on Footballers’ Wives. This time her character’s not about the glamour but keeping the family together.”
Returning cast members include Philip Martin Brown, Jason Done, Jaye Jacobs, Melanie Hill and Daniela Denby-Ashe.
Also joining the series is Sarah Jane Adventures and Doctor Who actor Tommy Lawrence-Knight.
