Huw is an amiable Welshman from Pontardulais, who is best friends with Lenny Wallace. They live in a squat in Albert Square, enjoying loud music and winding up Ian Beale. Lenny and Huw also operate a pirate radio station from the premises for a while. Ian tries to get them evicted several times — once calling the council to complain about noise pollution — and Lenny and Huw do everything they can to annoy him further.
During his time in Walford, Huw works in George Palmer's nightclub as a barman and in the café as a waiter. In 1998 Huw develops a crush on Ruth Fowler. Ruth sees him only as a platonic friend and unwittingly lets him get his hopes up for a relationship for a period of time. Huw eventually leaves the Square to live with Carrie Swann, an artist who is exhibiting her abstract art in the café.
