If we have your bank details
If you have already provided us with your bank details for the purposes of either receiving premium waiver payments or paying for your cover, there’s no need to do anything, as we will automatically transfer your payment direct to your bank account.
Similarly, if you have provided us with your bank details for Snap & Send claiming within the last 12 months, we will automatically transfer the money direct to your bank account.
If we don’t have your bank details
If we don’t have your bank details on file, we will issue you with a cheque. If however, you would prefer your payment to be transferred direct to your bank account, you can quickly and easily provide your details through our safe and secure online portal MyVhi.
