I had insurance with Churchill, until a scrape in a car park while unattended. The repair was dealt with very well.
However, on renewal the premium shot up, which was due to the car park claim (only £800).

I went to a local broker instead who got me a much better deal.
He said that the practice you have been a victim of Alistair is common with the big name insurers (Admiral, Churchill et al) as far as I understood from what he was saying.

All very good until something happens, then "whoa, where did that come from?".
