Just to add to the thread, renewed my car insurance for which I paid £549 last year, 25k miles a year, class 2 business cover and 2 other named drivers.

My renewal came in at £859, which I thought I could do better on.

Went to the usual comparison sites, Allianz were the first company I’d actually heard of offering the same cover with a few more bells and whistles for £689, still a 25% or thereabouts hike, but purchased that.

I went back to my current insurer online and clicked through the ‘cancel my renewal’ process at the end of which I got a ‘we don’t want to see you go’ message and an offer to renew at £752…

The usual shenanigans then.
