I don’t see what is new?
Minibus, bus and lorry drivers passing their test after the 19 January in categories C, CE, C1, C1E, D, DE, D1 or D1E will get a licence valid for five years. Every five years up to age 45, drivers will have to sign a declaration to show they still meet the required medical standards.

Lorry, bus and minibus licence holders
If you apply to claim your first lorry/bus test pass or renew
your driving licence on or after 19 January 2013, the
licence issued will be valid for a maximum of 5 years. This
affects you if you have passed driving tests for categories
C1, C, D1, D, C1E, CE, D1E or DE.
Once you have been issued with a 5 year licence you will
need to renew the licence when it expires (the licence
expiry date is shown in 4b). To renew the licence and to
renew your lorry and/or bus entitlement you will need to fill
in the application and medical questions on an ‘Application
for a lorry, bus or minibus driving licence’(D2) or the
renewal reminder form which we send you.
If you have already passed a driving test in one of the
above categories, the new rules will apply when you next
renew your driving licence or when you renew your lorry
and/or bus entitlement, whichever is earlier.
==================================================
Drivers who tow trailers
If you have passed your car (category B) test on or after 19
January 2013, to tow a trailer weighing more than 3,500kg
with a car or small vehicle (category B and B+E), you will
need to pass a test for category C1E.
If you got your driving entitlement before 19 January 2013
you will retain it. There are no further changes to rules on
towing trailers.
NOTE:- the interesting bit for B+E is that the rules for that depend on when the B was passed and not the B+E
