Depends which doctor you use

I used these http://www.elgv.com/contactus.asp

You pay £99 that gets you
Your medical, HGV highway code book, Provisional licence, Theory test and driver Assesment (how many hours you need).
Once you get your licence back and have passed your medical you then have your driver assessment,
Once this is done you then book your lessons,
I had 12 hours + test, failed once so add another retest and It stands me at around £1k
