When comparing car insurance quotes in London, give accurate details about your postcode, mileage, parking arrangements, occupation and how you use the car, as these can affect the price. Compare policies on a like-for-like basis, checking cover levels, voluntary and compulsory excesses, courtesy-car terms, windscreen cover and exclusions as well as the premium. A higher excess or telematics policy may reduce the quoted price for some drivers, but only choose these options if they suit your circumstances. Before buying, check that the provider is FCA-authorised and review the policy documents carefully.
