Former Preston College student Matthew McGivern won the role after auditioning for the part in September.
It will be his first TV role after graduating from the Guildford School of Acting in Surrey last summer and will see him move back to the North West to join the Hollyoaks cast and crew in Liverpool.
Matthew plays the part of Sam, the son of a new family called the Chen-Williams, and made his first appearance when the family were introduced to viewers over Christmas.
