Despite his lack of major television tournament wins, Webster entered the 2008 BDO World Championship as the number one seed due to his success in open events. This time around, Webster justified his status as joint-favourite for the title (alongside Anderson), as he beat Ian Jones in the first round, popular qualifier Glenn Moody in the last 16 and ninth seed Darryl Fitton in the quarter-finals. He played defending champion Martin Adams in the semi-finals, beating him 6–4 and earning a place in the final. He then beat Simon Whitlock 7–5 in the final on 13 January 2008, to become the third Welshman to win the World Championship of either organisation, after Leighton Rees and Richie Burnett, and only the second left-handed player to win the World Championship in either the PDC or BDO.
