2000 saw Beaven take more roles in shows aimed at adults rather than children. The first one of these was that of teenage rebel Sarah Addis in the series "Down to Earth". This was followed by her portrayal of Carys in "Arthur's Dyke" as well as small parts in "Doctors" (2003)} and "Casualty" (2004). She had previously appeared in "Casualty" on 25 January 1997, playing the daughter of paramedic Josh Griffiths; her character died in hospital from injuries suffered in a house fire.
