She is best known for her role as Jessica Arnold in the BBC school drama Grange Hill, in which she acted between 1994 and 1998.
She quickly adapted to life at Grange Hill and won a firm following among male fans.
The explanation was: Jessica had left Grange Hill in favour of sixth form college.
In September 1997, Simcock appeared in the CITV comedy drama Knight School as Lady Elizabeth de Gossard, having now changed her professional name to Amy Phillips.
Post-Grange Hill, Phillips has continued to make regular occasional appearances in various TV shows, the most notable being as Beth Partridge in the BBC series Rescue Me.
