The title was sealed last night on home ice as Tigers took care of their own business by beating Raiders 7-3, while rivals Swindon Wildcats, who needed to win and see the Shropshire side lose to keep their hopes alive, crashed 10-3 at Peterborough Phantoms.
The title success capped a superb week for head coach Tom Watkins and his men, who beat Peterborough Phantoms last Wednesday to clinch the NIHL National Cup.
Tigers made an impressive start last night with goals from Scott McKenzie, Brandon Whistle and Jonathan Weaver seeing them end the first period 3-0 up.
Raiders hit back to cut the deficit to one, but Tigers responded in style with Whistle, Jason Silverthorn Ricky Plant netting to make it 6-2.
With news of the Swindon result filtering around the rink during the third period, the players and fans were able to celebrate as the game came to a close. Raiders netted a third, but, fittingly, Tigers had the last say as Andy McKinney added goal number seven.
