driving licence

http://www.direct.gov.uk/en/Motoring/DriverLicensing/NeedANewOrUpdatedLicence/DG_4022086 According to this link you should be able to renew it online, this licence then lasts a further 3 years. At this stage it is only if you need a 'special' licence to cover certain categories that you need a medical examination.

You may have problems renewing online, if;-

1. You don't have a UK address - you are supposed to be UK resident to renew online.    ....or
2. You [like me] have the old style paper license only [i.e. - no photo license]

Good luck

I have a few friends in your 'category' who got a bit panicky - one of them used his son's address in the UK, another did it totally 'online', so I'd go along with Andiamo's advice. Surely you have somebody in the UK who'd let you use their address if necessary? Nobody needed any certificate from a doctor.
