In 2002, Wallwork moved to West Bromwich Albion, where he was the Player of the Year for 2004–05. He was not always a regular in the side however, and spent time on loan at Bradford City, Barnsley and Huddersfield Town. His spell at Barnsley was cut short when he was stabbed several times in a nightclub, suffering wounds to his hand, stomach and back, which caused him to miss more than two months of the 2006–07 season. Wallwork was transferred to Sheffield Wednesday in January 2008, but was released just four months later.
