Early life Waterhouse was born in Hertford, but brought up in Haywards Heath, Sussex. The son of a solicitor, he was educated at St. Wilfrid's Primary School, West Sussex and Shoreham Grammar School.

Doctor Who Adric was a companion of Tom Baker and Peter Davison's Doctors from 1980 to 1982. Waterhouse was the youngest actor to play a companion and Doctor Who was only his second professional acting role.

On 31 July 2013, Big Finish Productions announced that Waterhouse would be returning to play the role of Adric in a series of Fifth Doctor audio plays, beginning in 2014 with the Fifth Doctor Box Set followed by, so far, two trilogies of stories and the adaptation of Fifth Doctor and Seventh Doctor crossover novel Cold Fusion.
