Selt progressed through to the semi-finals of the Haining Open, losing 4–1 to Stuart Bingham.&lt;ref name="2014/15"&gt;&lt;/ref&gt; His first win at the venue stage of a full ranking event this season came courtesy of a 6–0 whitewash over Hammad Miah at the UK Championship. Selt then knocked out Xiao Guodong and Rory McLeod both 6–4 to face Ronnie O'Sullivan in the fourth round. O'Sullivan made a 147 in the final frame as he won 6–0, with Selt saying afterwards that despite having numerous chances throughout the match he never settled. Selt responded in his next event by winning four matches to reach the quarter-finals of the Lisbon Open and then defeated Judd Trump 4–1 and Barry Hawkins 4–2 to play in his first final in a minor-ranking event. He took the opening frame against Stephen Maguire, but went on to lose 4–2. His first quarter-final in a ranking event this season came at the PTC Grand Final after he eliminated Oliver Lines 4–1 and Chris Wakelin 4–2 and he led Mark Williams 3–1, but could not reach the first semi-final of his career as Williams would knock him out in a final frame decider. Selt's season looked to be ending in disappointment as he trailed Jimmy White 7–2 in the second round of World Championship qualifying. However, he took eight of the nine frames upon the resumption of play and won in the final round 10–8 against Tom Ford. In the first round Selt lost another opening session 7–2 this time against Barry Hawkins. He also went on to be 9–4 behind but then won five frames in a row which included back-to-back centuries and a 94 break. He couldn't win his first match at the Crucible Theatre as he lost the deciding frame. Selt finished a season inside the top 32 in the rankings for the first time in his career as he was the world number 30.
