In March 2015, White had a phenomenal run of form. He won his first professional title at the Shoot-Out, the tournament where each match is decided by one 10-minute frame, White won the title by taking the lead in the final against Xiao Guodong with six seconds remaining. He then won the Indian Open after reaching the semi-finals of a ranking event for the first time in his fifth attempt by beating Chris Wakelin 4–2. White then defeated Mark Williams 4–2 and saved his best performance of the week for the final against Ricky Walden where he scored a total of 419 points to Walden's 27 in claiming his first ranking title with a 5–0 win. His prize money for winning back-to-back tournaments stood at £82,000. White made his debut in the PTC Grand Final and lost 4–3 to Martin Gould in the first round. A pair of deciding frame victories over Ken Doherty and Stuart Bingham helped him to the last 16 of the China Open, but he was eliminated 5–1 by Robert Milkins. White's season ended with a 10–5 defeat to Craig Steadman in the second round of the World Championship qualifying. His year was reflected in the rankings as he rose 10 places to end it 17th in the world.
