Dance studio/class (hiphop/kpop) in london

Hii I’m a year 11 student who loves kpop (specifically nct/Riize or boy groups) I’ve always wanted to join a dance club/crew but I don’t know how to. I don’t mine if it’s an actual crew or if it’s a hihop dance class/studio or anything similar. I just want to grow my passion for dance!
I would prefer it was free 😭
