When I was in 6th Year (Scottish 6th Form) I emailed RAF Prestwick to see if they could offer me work experience. Unfortunatly they were unable to however did offer me a days visit to Prestwick Centre (Owned by NATS where the Civi's and Military used to work). I was able to sit in on Scottish Mil sectors and had a good chat to lots of the RAF guys and the NATS staff. Subsiquently I've given up on the whole controlling thing and become a mere tels (ATC) Engineer but definitely drop RAF Northolt an email explaining your situation.
Feel free to PM me if you need a hand.
Not an ATCO but still in the right company
