Start by gathering your driving history, vehicle details, estimated mileage, address and information about how the car will be used. Decide whether you need third-party, third-party fire and theft, or comprehensive cover, then compare quotes from insurers or comparison services. Check the policy details carefully, including excesses, exclusions, permitted drivers and cancellation terms, before buying from an FCA-authorised provider. After payment, the insurer should send your policy documents and cover usually begins on the agreed date, so keep the documents and check that the details are correct.
