After finishing second in the group stage Británicos advanced to a three-team final in the tournament.
Británicos showed their development this season by dispatching rivals Iberos 5-0, revenge against the side who defeated them in the pre-season Iberos cup.
Ben Carroll opened the scoring before Ollie Mills widened the margin with a back-post header.
Mills scored another soon later after a mix-up at the back before Oli Povey put the game beyond doubt with a run and finish.
Carroll scored his second to put Británicos in prime position to win the competition.
After Independiente defeated Iberos 2-1, it was all to play for in the last match.
After a frustrating first half in which the Independiente goalkeeper made multiple saves, Carroll scored two goals in the second half to win the game and tournament.
The results ensure that the B team only lost two games out of 18 in all competitions.
