Stephen is a children's entertainer and magician. He also is the uncle to Molly and Dave, he is referred to by Basil as "Mr Stephen". He only starred in the first four seasons from 2002-2005. In those seasons, Basil uses him as the foil of his gags, such as tying him up, or getting him sacked from his job. But sometimes, Stephen gets his sweet revenge.

In Series 5, his current job is working in a burger stand in Hollywood, maybe to get away from the show since he had enough. In the same episode, his Irish cousin named Liam ended up replacing his role.

In recent years, Christopher Pizzey reprised his role as Mr Stephen for Basil's YouTube channel and stage shows. Where he is back to being Basil's foil for jokes.
