I have just moved and need to change this on my driving licence. However, I'm getting married next June so will also need to change my driving licence then to reflect my married name. Will I get into trouble if I wait until after I'm married and do both the changes at the same time?
Yes, you are legally obliged to inform them ASAP of any change of address. This is much more important than your change of name - they can still trace you under your maiden name, but cannot guess your new address! It doesn't cost you anything so just send it off!
I moved 12 years ago and still haven't changed my address. I also lost my license in the move and haven't had that either. The DVLA always knew where I was though as I received all my reminders. So from my experience I'd say wait...
I would wait as well. I have moved twice in the last three years and am due to move again soon and it hasn't made any difference. Don't worry about it.
I would say wait as well, I didn't change mine for years after moving (actually when I found out I'd been driving on an expired license for 2 years) and no-one was any the wiser!
