After 7 months of waiting, my licence with my amended personal details and updated photo has finally been issued. Very difficult to get through to DVLA on the telephone (impossible on Web chat) but when I did the advisor was very helpful. To be fair, my application took longer because there was a medical enquiry. It took 3 months for them to contact my Doctor and then almost 4 months to review the information my Doctor sent back. A long wait but got there in the end. 7 months seems a bit extreme! As I say, helpful advisor though
