I recently had my annual renewal notice and my car insurance was greatly increased from last years. By shopping around though, I found Flow Insurance and went with their comprehensive policy.
I'd never heard of them, but they're the internet-only arm of LV. Everything is done online and the only time you can phone them is if you have a claim to make. All changes are made online by yourself, so there are no admin fees (for a change of address, for instance). I lowered my premium by £120 from what I paid last year.
