Common mistakes include giving inaccurate details about your address, mileage, occupation or where the car is kept, as these can affect how a policy is assessed. Avoid fronting, where a more experienced driver is wrongly named as the main driver, and disclose modifications or regular business use. Check the policy excess, exclusions and level of cover rather than choosing on price alone, and review your details at renewal. If you are unsure what must be disclosed, ask an FCA-authorised insurer or broker before buying cover.
