Car driving licences gained before 1 January 1997 are normally valid with all the entitlements including C1, C1E, D1 and D1E, until the age of 70 when they need to be renewed. However, all photocard licences have to be renewed every ten years to update the photograph.
Irrespective of previous renewals all drivers have to renew their driving licence when they reach the age of 70. Also if you change your personal details (address or name) you will need to inform DVLA which will issue a new photocard licence.
When it comes to renewal of licences there are two distinct groups of licence, car and motorbike licences (including category B and BE) known as Group 1 licences and lorry and bus licences (including categories C1, C1E, D1 and D1E) which are referred to as Group 2 licences. The difference between the two groups is the frequency of renewal and the higher medical standards required for Group 2 licences.
For pre 1 January 1997 licence holders, the increased frequency of renewal and higher medical standards for Group 2 licences do not come into effect until the age of 70. But for those with post 1 January 1997 licences, Group 2 licences have need to be renewed at the age of 45. From this point the Group 2 licence categories need to be renewed every five years until the age of 65 when you need to renew this element of your licence every year.
Renewal of Group 2 licences entails the submission of application form D2 and form D4 which has to be completed by a doctor and possibly an optician to check for the higher medical standards required for Group 2 licences, there will be a charge for this service.
