Insurance Companies

I know Direct Line don’t appear in their results lists but i wondered if anyone knew of any others?
Thanks.

Can anyone give me a list of car insurance companies that ARE NOT on comparison web sites like Confused.com? My insurance is up soon and I want to make sure I get the best deal by checking with as many of the big companies as possible. I will be using Confused, but I also want to check with the ones that aren’t on there. Thanks.
