His debut in BDO events came at the 2004 Welsh Open, losing in the last 32 to Alan Tabern. In 2007 he won the BDO Gold Cup, beating Scotland captain Mike Veitch in the semi-finals, and Welshman Matthew Quinlan in the final. Chisnall then fell two games short of qualifying for the 2008 BDO World Championship, losing to Robert Thornton. A few days later Chisnall was again beaten by Thornton in the Winmau World Masters.
