Flew into Durham/Teeside today for my solo navigation exercise; ATC were very helpful. Ideally you should be assigned stand 9 outside the tower; otherwise it could be a long walk. Occasionally you will be met by the Duty Officer who will escort you through the main terminal to pay the landing fees at the 'Customer Services Desk' otherwise you have to go through a different security gate near the tower, walk around the perimeter fence, back into the terminal car park via the hotel gate and then into the main terminal. Also you will find a phone next to the customer services desk for booking out.
Security will ask for license/ID and depending on the personnel on duty expect to remove shoes, belt etc.
This is my experience from two visits (dual + solo), maybe someone more experienced could advise further.
