WARNING!! I had to send my driving license off for the address to be updated. I got my new one back no problem within a couple of days. I was in Hein Gerike getting a new lid on Sat and told them how quick it had been. They asked to see my license and gave a sigh of relief when they saw it. It seems that the DVLA have been sending replacement licenses back without the bike entitlement on it. Then the person has to re-sit their bike test to get it back. The guys in Hein Gerike in Preston said that they had seen this more than a few times. There advice was to photocopy your license before sending it off.
