How to cancel Admiral Group plc by mail
Note your account details
Check the policy number, the registration number of the vehicle and the date you want cover to end before anything else. A request that does not match the account on file at Admiral Group plc is the easiest one to set aside.

Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to CF10 2TH Cardiff. Keep the tracking number it gives you.
File the delivery record
Once the letter is delivered, the date on the receipt is the date Admiral Group plc was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a car insurance policy
Car insurers cancel by policy and by effective date, and a gap in cover is a real risk, so the request has to name the vehicle and the exact date cover should stop, ideally after the new policy has started.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
