In February 2010 Hull took part in the pro-am Finnish Snooker Challenge, which featured a number of notable professionals. He impressed, beating Darren Morgan, Ken Doherty and Matthew Stevens on the way to the final, where he lost to Mark Williams. This result encouraged Hull to take part in the Q School tournament in 2011 in attempt to qualify for the 2011–12 main tour, which he did successfully in the first event. Due to lack of sponsorship he only played in a handful of events during the season with his best run coming in qualifying for the 2011 UK Championship in November where he beat Lucky Vatnani and Yu Delu, before losing to Peter Lines 4–6. Hull did not enter another tournament after this and finished the season ranked world number 84, outside of the top 64 who retain their places for the 2012–13 season and therefore did not retain his spot on the main tour. In the 2012–13 season Hull entered qualifying for the World Championship as an amateur, where he lost in the first round of preliminary qualifying 2–5 to Paul Wykes, despite making a 137 break during the match.
