Hi my name is Gemma, I own a kickboxing academy just outside of sheffield in a place called Dore. Its not very big at the moment, but is due to expand. I cover a syllabus for the BKA and a small group of schools called the UK MARTIAL ARTS GROUP.
I appreciate that this is not exactly what you are looking for, but my academy would train you from the grade that you are in kickboxing, it would not expect you to start afresh for joining!
If you are interested you can e-mail me @ Trinityempire@hotmail.com and I can send you an information pack.
