Yep, go for vandalism on the onlone comparison sites but liek Vic says, best to ring through to buy the policy and check with them.
Vic, the advice you give often says to check with the insurer which is sound advice but I just thought, what if you bought from Swiftcover? You can't check with them as they are online only, so can they ever refuse to pay out in a case like Cuns mentions where they might not agree that its a vandalism claim?
