He was never able to establish himself with the "Baggies" making 50 appearances in four seasons which ended with promotion in 1992–93. He ended his career with a season each at Peterborough United and Chester City before entering non-league football with Halesowen Town.[3]
In 2003, Hackett was named co-manager of his hometown club Stourbridge alongside Jon Ford, but became the sole manager in 2005 with Ford as his assistant. Stourbridge won promotion to the Southern League Premier Division with two promotions in three seasons under Hackett's management, as well as reaching the FA Cup proper rounds for the first time in the club's history. In May 2019 Hackett announced he was resigning as manager after sixteen years in charge, following Stourbridge's defeat to Alvechurch in the Southern League play-off semi final.
