NATS dominate ATC in the UK, and with them if you were to apply now the earliest you would start college is July 09, but probably months later. Then its 6/9 months at college, and live training after that.
But I notice you're aged 38, I think to start from scratch with NATS you need to be <35.
Perhaps look at smaller airfields, Biggin Hill or Shoreham if you live near the Brighton mainline.
