In the fourth frame, a break of 37 by Sandhu proved the difference, winning the frame 72-23 and taking the title 3-1.
Bradford will once again be represented at this year’s UK Snooker League Championship, with the team being part of an invitational 16- team event at the Northern Snooker Centre in Leeds this weekend.
The team first took part two years ago and were runners-up to Norwich in the final, while last season they made it to the quarter-finals.
There are two round-robin groups of eight, with the top four from each group going through to the knockout stages.
The event gets underway at 11am on Saturday and continues from 10am on Sunday.
The squad is ten-time Bradford champion Wayne Cooper, four-time Bradford champion Gareth Green, Anthony Green, Mark Slater, Josh Walker and Kevin Firth
