If you're not sure if your car is already insured, you can check the Motor Insurance Database – the central record of all insured vehicles in the UK – for a £10 admin fee. If you have an accident, you can also use it to check if the other drivers involved are insured.

If you need the insurance company details, you can send a request form for the information. You may need to send some ID, and you'll also need to pay a fee.
