tried co-op? i've always found them pretty good, and their call centres are UK, so no trying to explain something to someone who has no clue what you're on about, while you can't understand their bloody accent! with 67% (5 years) no claims, my 2 ton transit was costing £379 a year. until i backed into a jeep... 45% (2 years) no claims, gone up to £600. but i'm about to lose all my no claims. ouch and bugger.
but, yeah, they're pretty good.
*edit* that's fully comp. co-op don't do 3rd party, fire & theft.
