I have just been through the nightmare insurance racket, and have 3 points, I have been told any more and the premium will increase dramatically.
Last year my insurance was 440 quid, this year it is £575, just because i decided to stop insuring my car at my parents hosue, where it can be parked in a driveway at night.
Incidentally out of 32 companies called, Gladiator in Coleraine were the cheapest broker, they have some great medieval graphics in their yellow page's add, and some equally cheesey hold music when you call them.
