At the end of the 2011 FA WSL season, Unitt put in a transfer request after eight years at Everton. Following negotiations a move to Birmingham City was announced in February 2012. After her time at the club was disrupted by injury, Unitt rejected Birmingham's offer of a contract extension in January 2014 and left the club as a free agent. She signed for Notts County on 30 January 2014, only to suffer an injury to the cruciate ligament in her other knee during the 2014 FA WSL season. In December 2014 she agreed to stay with Notts County, combining her rehabilitation with a place on the club's coaching staff.
