One of my guys, John Hands, teaches in Leeds city centre. He teaches Jun Fan Gun Fu, Kali and Self-Protection. John is a former Royal Marine and Doorman with years of frontline experience, he is also a great teacher and a really nice guy. That may not be the specific Chinese route you were looking for, but I wanted to let you know about him.
His website is

If thats not your thing, I used to live and teach in Yorkshire so drop me a PM with your location and I will see if I can help.
