Never experienced a voiding of the policy due to missing out material facts, but I suppose if it were to come to it you'd have to go to the ombudsman to get a ruling.pvr said:Ok, but I was actually referring to cases where they declined to pay out at all as you had fitted a different exhaust or something like that, not where there is just a shortfall in the payment.
In my experience, they only reduce the cover to exclude the modification, so if you had £20k of mods on your £5k car you'd only get £5k back.
