Nah, You dont really see much of an increase in your premiums tbh, I think mines perhaps went up £100 after a month and a half ban... again from an english magistrate... I think its when you have more than about 6 points that they really start to pay attention....
Also, I belive that bans are not like points in the respect that when you have served the ban, its a spent conviction, unlike points, that are valid for what? 3 years, to be removed from your licence after 4years, and no longer have to be declaired after 5 years...
I think its only something like 6 months till I have a completely clean drivers License again...
