If your motor insurance policy lapsed or expired at renewal, then your renewal invite document issued via email 28 days before the due date includes your proof. This can be found on page one of the document.
If your policy was cancelled mid-term, you will receive this via email on the date of the cancellation request. Please check your junk or spam folder as on occasion, this proof can go there in error.
Please note that you wouldn't usually receive a no-claims bonus for home insurance in the way that you would receive this for a motor insurance policy. If you've made any claims or reported any losses with a home insurer, then the central insurance database would reflect this.
However, if you have made any claims or reported any losses whilst insured with Policy Expert and require further details about this, please let us know as we can obtain these details from the relevant department for you.
