To find a cheap car insurance online quote, compare several policies using the same accurate details about your car, driving history, mileage and circumstances. Check more than the headline price, including the excess, cover limits, exclusions, courtesy-car arrangements and any fees for changing or cancelling the policy. Only choose optional extras, such as breakdown or legal expenses cover, if they are useful to you, and never understate your mileage or omit modifications. Before buying, check the insurer or broker is FCA-authorised and read the policy documents carefully.
