Hi!
The tda is probably your best first port of call (
http://www.tda.gov.uk/). There are loads of ways of getting into teaching; are you looking to do a degree (normally a seperate degree in something, mine's in English)? If you have a "normal" degree then often you can go on to go a PGCE (post-grad cert. ed,) which gives you QTS (qualified teacher status).
I'm starting my teacher training now/in the next few months. I've been working as a music teacher for a couple of years and have been brought upn in an educational family. My mum was a science teacher, then a head, now she runs an educational consultancy company and is responsible for alot of Ofsted. So I know a fair bit about teaching! PM me if you need anything lovely x
