In Leeds there is Dynamic Pro Wrestling, they're a solid promotion who I'd definitely take a look at as you live in the area. I'm from Hull, so as a fellow Yorkshireman I'd say that's your best bet.
When you get on shows and finally get to wrestle it's incredible, even if your first match is a rumble like mine was it's definitely a moment you will remember. You meet a lot of cool people, and equally a lot of tools but it's awesome. Let me know if you need any help finding training or whatever I like to help = )
Good luck
