We are currently with CGU (DH is in insurance, used to work for them. And he's not one of those dodge door to door sellers haha) But we've er, had a few minor 'incidents' and they've been great at replacing stuff and getting it fixed. Home and contents are with them too. (We don't get any special treatment, most of the dealings were after we left with people who don;t know he worked for them.)
Though - we are switching to QBE when we replace our car. They're cheaper and he said something about their policy wording being a bit more friendly?
Obviously I let him handle it but thats what he's said about it.
