The daughter of Peggy and Geoff Moore, the latter a jazz musician, she was educated at Hesketh Fletcher School, Atherton, and Leigh Sixth Form College, before training at the Royal Northern College of Music.
In 1986, she was cast as the alternate Christine Daaé in the original cast of The Phantom of the Opera. She played three shows each week instead of Sarah Brightman. When Brightman left the production after a year, Moore then took on the role full-time. She was voted "favourite Christine" by the Phantom Appreciation Society.[1] In 1989 she left the role to play Ellen in the London production of Miss Saigon.
She was due to return to the London production of The Phantom of the Opera in September 2013, this time to play Carlotta Guidicelli, but her run was cancelled due to injury.
In the 2019 National Theatre production of Follies, she played former Follie girl Hattie Walker and sang one of the shows most popular songs, ‘Broadway Baby’. She followed this by playing the dual roles of ‘Miss Andrew/Miss Smythe' in the 2019 West End revival of Mary Poppins, the run of which was stopped on 16 March 2020 by the COVID-19 outbreak.
In 2022, Claire starred in the World Premier of The Great British Bake-Off: The Musical at the Everyman Theatre in Cheltenham, playing the role of a contestant called ‘Babs’. When that show transferred to the West End in February 2023, Claire continued in the same role alongside many of her co-stars from Cheltenham.
