Those of you with UK driving licences, don’t forget that you must renew your photo every 10 years. Just renewed mine (£20) online, but to do this you must have renewed your passport in the last 5 years (they take the passport photo and transfer to your DL) and of course the people at your UK address must be aware of what you are doing. You must also be "resident in the UK" ;)
I also did not realise mine had expired, and the nice man at the car rental in the UK told me so, but still managed to hire a car!! I renewed mine with the paper form, and sent it to my UK address. Received it back within 10 days – no questions asked!!
