Confused.com have always come back expensive for me, and most people i know.
I think it only works if you have like 30NCB and are like 50yr old or something like that, otherwise its useless for younger drivers.
I have always found adding my mam onto my insurance lowered it £350, just for adding her as a named driver on my policy, she is 53 with full ncb, so it dropped it quite a lot. Might be worth a shot adding someone like that to your policy and see if it makes any difference.
But i always found Churchill, elephant, admiral, belldirect to be cheapest, and im 22 with 1yr ncb, and im paying £685 Fully Comp on a vectra sri 150, doing 10k a year, parked on the road over night, and its completly standard.
PS.....What companies do part time trade insurance?
As i valet other peoples cars, just for the extra cash here and there, and its a pain in the arse to do. As i have to get them to drop their car off, and then i take them home, and pick them up when its done, so they can get their car, would be so much easier me getting there car, and driving to mine, then back to theres when done.
