A lot of the stuff on TTT's link is just plain WRONG !
ANY driving licence used in the UK MUST BY LAW give your correct postal address.
I have lived overseas twice, once in Zambia and once in Saudi Arabia,in both cases I had to use my overseas licensees to drive in the UK as I was no longer a UK resident.
Again as said, as long as you do not have an accident you will almost certainly get away with it,but not if you have an accident , the insurance company will refuse to pay out and void cover. That will mean you will be personally liable for damages that could be in the £millions and have a conviction for driving without insurance and get the car crushed ! Just not worth it !!
