I've just insured with LV.
Was with Churchill last year, paid £515, this year they wanted £700 and something.
45 yrs old, a reasonable area in Herts, 9yrs + NCD.
£411 with LV, with protected no claims, legal, and courtesy car.
No knowledge of what they would be like in the event of a claim though, and don't really want to find out to be honest.
