If you get to the stage in life when your driving licence has to be renewed, and you have a notifiable condition, for example a cardiac pacemaker, do not leave your application to the last minute, instead use all of the 90-day window. If it winds up in the hands of the DVLA medical team, and most probably it will, they will take six weeks to process it, and during that time your driving status will be uncertain. Should you need to hire a car during that period, forget it, for you won’t have a licence. The old one has to be sent in with the application.
