Laura was born in Little Sutton, Ellesmere Port, Cheshire. With a voice described as that from a love child of Rod Stewart and Stevie Nicks, Critchley started singing when she was 7 years old. She wrote her first song, "Change", at the age of 16. It received radio play on BBC Radio Merseyside on the Billy Butler and Jimmy McCracken show. She got to the last 50 in Fame Academy in 2001, and appeared as Jessica Simpson on Stars in Their Eyes.
In 2006 she moved to London and within 3 months was signed to independent record label Big Print Records, owned and run by Andrew Gemmell and Jeremy Marsh (RCA Telstar). She toured with the Sugababes in March 2007, with Ray Quinn in October 2007, with Deacon Blue  in November 2007, and with Boyzone in May 2008.
Critchley's début album, Sometimes I, was released on 19 November 2007. Radio 2 Terry Wogan has praised Critchley saying that her single was an excellent single and that she was one to look out for.
Her first single, "Sometimes I" was released on 21 May 2007. Produced by Steve Power, the man who worked on many of Robbie Williams' hits with him, the single did not chart, but did well on the video channels. The second single "What do we do" was on the Radio 2 playlist on the Terry Wogan show, and was released on 12 November 2007. Her third single is a remix of "Sometimes I", by Ash Howes (who has worked with Girls Aloud and the Sugababes) and was released on 25 February 2008. Critchley's fourth single "Today's Another Day" was released on 16 June 2008 and was a radio hit, reaching number 4 in the independent charts. On 6 July 2009, Critchley releases her single "Feel Proud" which she wrote with UK troops in mind. Profits will go to the Help For Heroes charity. Critchley's songs have been on the Radio 2 playlists as well as many regional stations such as Radio Ulster.
Having supported The Sugababes, and Boyzone on their respective arena tours, duetted with Ronan Keating and sung for Robbie Williams, Critchley has already made a substantial impression on the UK market. She has performed over 200 times in the last 18 months, for audiences from just an intimate 35 to that of 35,000, from the RDS stadium in Dublin to the Wight festival. She won the best live performance award at the Irish Entertainment Awards in October 2008.
Critchley performed her debut American showcase on 1 May 2008, to which many record execs went. Jeff Arch (the Sleepless in Seattle writer) also directed her video for the single "Today's Another Day".
