I've been asked to "put something about this on the site", so here it is. The only "Scam" is the UK government will relieve you of £1000!
The photo card part of your licence needs to be updated (at your expense) every 10 years (usually, there are other, special, cases) from the date of issue. If you fail to renew it the licence will still be valid to drive with, it just means that the photo is out of date.
The DVLA have stated that renewal notices will be sent out, to the address on the licence (you did remember to notify the changes when you moved, didn't you?), before the due date so there should be no real problem. These type of licences were first issued in July 1998 so the first batch of renewals has already been dealt with and anyone who was "missed" would now face a fine.
DVLA figures reveal that while 16,136 expired this summer, so far only 11,566 drivers have renewed, leaving 4,570 outstanding!
While the driving licences will still be valid for driving (the Association of British Insurers and the Department for Transport have stated that insurance cover was not affected if drivers failed to update their photocard), failure to send the photo licence, the paper counterpart and a new photo, along with a £17.50 fee, will leave the driver open to prosecution and a fine of £1000.
It may be prudent for you to check the photo expiry date, just in case the details held on the DVLA computer are incorrect or the renewal notice got lost in the system somewhere. It is displayed on the front of the photo card licence as item 4b.
