I use Swinton bikes - wouldn't do it again as they charge a hefty admin fee when you make changes to the policy (and leave, I believe) I found AVIVA fabulous last year - I was burgled and the bastards stole my beemer off the drive on the way out. AVIVA Paid out over £6000 within 10 days of the theft.

They're all much-of-a-muchness though tbh.
