Competing in the six qualifiers for the 2018 UK Open, Part reached the last 32 stage of the fourth event. The £750 prize money for this was enough for him to qualify as one of the 128 players to take part in the televised stages of the tournament, his first since the 2015 UK Open three years previously. He beat two amateur qualifiers in the first two rounds of the tournament, and followed those wins up with wins over David Evans, Ron Meulenkamp and Mervyn King to reach his first televised quarter final since the 2012 Grand Slam of Darts, and his first quarter-final in any PDC event since the 2014 Austrian Darts Open. He lost at the quarter-final stage to Robert Owen. The £11,500 prize money he collected for this result is his highest earnings from a single event since the 2013 PDC UK Masters, also held at Butlin's Minehead.
