Belgrave Wanderers have been crowned champions of the Priaulx League for the seventh time in their history.
Vale Rec's 2-2 draw with St Martin's means no-one can now catch the leaders.
First team coach Glyn Smith told BBC Radio Guernsey: "It's very special to me, it's the first championship I've been involved in.
"We had the points in the bag which put the pressure on the other clubs, it was a nice position to be in and we can now enjoy ourselves on Tuesday night."
Bels last won the title in the 2009-10 season and Smith is hopeful this success can continue.
"We don't have any players over 28 in the squad so we hopefully we can improve," he added.
"We had 27 players at training the other night in the freezing cold which is the most I've ever known, it shows how motivated they are.
"They've worked very hard to achieve this."
