Thanks for all the replies.
i was hoping that there was some discounts for being a member of certain things as I have read that if you become part of a drivers club or something you can get offered discounts with particular insurance companies, but wasnt sure how true this was.
im currently with Diamond but unfortuately due to the fact they had to pay me a chunky cheque at the beginning of the year due to a write off accident they dont like me very much anymore. also means I only have 1 years NCB, plus points. not a good combo for insurance....

haven't sent me my renewal price yet but I'm sure i will be shocked even with the expectations of it been ridiculously high!! from looking around they wont currently insure me with an excess of anything less than £950
I have in the past haggled with the whole EUI clan (admiral/Diamond/Elephant) and its paid off, but not sure it will since the accident. going to be interesting and costly I think...
I am pretty sure that they just have a big hat in the middle of the office and pull out numbers every time someone asks for a quote, the quotes don't make logical sense.. for example apparently its £20 cheaper for me to be insured in september than it is in August... yeah, 'cos that makes sense. pffft.
