well done a hell of alot of searching on web and the best i can get for my son first year is 620 tpft cover from quin direct with all the benifits and break down cover/homestart as well
Just be careful with quin if he is still on a provisional. They gave me a quote for £700, when I passed I would have had to pay about £2000 to keep the policy. Make sure you ask them what they will charge extra (if he is still on a provisional, if he's passed then that is an amazing quote)
Unfortunately I'm pretty much the highest risk group around. Single student 17yo had liscence 0 years no ncb. Best I could find by a mile was direct line at £1800 (for a cinq) closest competitors came it at about £2200. Next year it should drop to below £900
