What do i need to get a Full Bike Licence?

[FooFighterr]

Right. I know roughly what needs to be done. But. I'm 18 years old. Currenty riding a 2012 Sym XS125-K on a CBT. I know the regulations are changing in Janruary. So i want to pass my full bike test. I know that i can do this. Get any bike i want. Restrict it to 33hp, Then derestrict it after two years have passed. Just wanted to know if it'll be cheaper because i'm already on the road? If so. Can someone give me a rough price for me to do my full bike test?
Thanks in advance!

I've been riding for about 4/5 months now. But i feel as confidant as i need to be. I'm out on the bike for most part of the day after work. Plus I've had a go at my dads Fireblade1000, Stupid, I know. But atleast i know i can handle it right?
