Garvey married the television presenter Adrian Chiles in September 1998 in Swansea. They lived in Shepherds Bush, west London and have two daughters, both born in Hammersmith and Fulham, London: Evelyn Katarina (born January 2000) and Sian Mary (born March 2003). Chiles is known to be a dedicated West Bromwich Albion fan; when asked in 2004 whether the football club would be promoted that season, Garvey commented: "I flaming hope not. Last time Albion got promoted, I gave birth nine months later."
