Got to renew my car insurance.

My wife has had a whole load of convictions recently and a few accidents in her company cars. Wanted to take her off the policy to reduce the cost but turns out its cheaper to have her on the policy.

Trying to get competitive quotes but need info. We’ve obviously got details of her convictions but finding out the details of what has been claimed is proving a nightmare. Anyone got any ideas how I can get details of them? She’s worked for three different companies in the last 3 years and had her own car. All of which I’ve got no claims info for.
