my lads just been done for speeding [twice now] idiot that he is,

he only passed his test a yr ago so he now has to do it all again, my question is, has anyone else done this and what sort of insurance premium will he be looking at come renewal time as when he declares this id expect them to run a mile,presume if he passes his test again he can still see out the remaining insurance? or does he need to tell them now?
