This will sound really stupid - I know that my car insurance is due next month but I can't remember who it is with or find the paperwork. Other than wait for the renewal notice is there another way I can find my insurance details?
"I've forgotten who my insurer is" comes up as a question frequently on AB. The first thing that's always suggested (quite sensibly) is to check you bank (or credit card) statements if you pay by direct debit or online, or your cheque stubs if you use that method of payment.
Under the regulations of the Financial Conduct Authority, your Insurer/Broker should give you at least 28 days notice prior to the expiry of your insurance.
