Compare several quotes, but check that each is based on the same details and level of cover, as comparison sites may not show every provider. Look beyond the premium at the compulsory and voluntary excesses, exclusions, cancellation fees, courtesy-car arrangements and claims service. Be accurate about your mileage, driving history, occupation and where the car is kept, because incorrect information could affect a claim. Before buying, check the insurer or broker on the FCA Register and read the policy documents carefully.
