The Hythe Dragons Kickboxing Club managed to scoop five top awards at the Southern Open Series Final in Crowthorne.
Leah Crouch, 12, and Connor Wells, 10, both took two titles.
Crouch won the light continuous category while a third place in the semi-contact category gave her enough points to become Grand Champion.
Wells also picked up two trophies when he took the Grand Championship title in the semi-contact category after beating team-mate Shane Davis in the first round.
A first place victory over Luke May (Watford) in the light continuous category saw him collect his second trophy.
Hythe's chief instructor Martin Binge took the honours in the overall 80kg men's semi-contact division.
Hythe's successes came despite their training facilities being destroyed by fire last year.
They are temporarily training in the Jubilee Hall in Fawley but are still on the lookout for sponsors to replace equipment and training kit lost in the blaze.
