In June 2012, Gurney won the England Masters, Northern Ireland Open and the Tom Kirby Memorial Trophy. In winning the latter, he earned a spot in the preliminary round of the 2013 PDC World Championship, where he edged out Robert Marijanović 4–3 in legs. Gurney then beat Andy Smith 3–1 in sets in the first round. He lost each of the first three sets in a deciding leg in the second round against Dave Chisnall and outscored him in the 180 count, but was beaten 4–1. In January 2013, Gurney entered Q School in an attempt to win a two-year PDC tour card and was successful on the second day by winning six matches, concluding with a 6–2 victory over Paul Amos. His best result in his debut year on the tour came at the German Darts Championship, where Gurney defeated Colin Lloyd, Ronnie Baxter and Simon Whitlock in reaching the quarter-finals, but his run came to an end when he lost 6–2 against Peter Wright.
