How Mileage Affects Car Insurance

Why insurers ask for annual mileage

Mileage is one indication of how much time a car spends on the road. More miles can mean more exposure to collisions, although mileage is only one part of the calculation. The type of journeys, driver, vehicle and location also matter.

For a closer look, read how mileage affects premiums and annual mileage and insurance cost.

Estimating your mileage sensibly

You are not expected to predict the future exactly, but the estimate should be reasonable. Look at MOT records, service documents or the difference between the current odometer reading and last year’s figure. Then allow for planned holidays, a new job or any other change in regular travel.

Our guide to making a mileage estimate explains what to consider.

Commuting and business mileage

Mileage and class of use are not the same thing. Social, domestic and pleasure cover may not include travel to work. Commuting may cover journeys to one regular workplace, while business use can be needed for travel between sites, customers or appointments. The definitions vary, so check the policy wording.

Low-mileage and occasional drivers

Driving fewer miles may help with some insurers, but the cheapest policy is not always a specialist low-mileage product. Compare ordinary annual policies as well. Check minimum charges, mileage limits and what happens if your circumstances change.

Useful pages include insurance for people who rarely drive, low-mileage discounts and cover for occasional drivers.

Telematics and mileage limits

Some telematics policies record mileage directly. Others focus mainly on driving behaviour but still set an annual allowance. Read the terms carefully, including charges for extra miles and any restrictions on night driving. Learn more in our guides to telematics insurance and black-box cover.

If your mileage changes

Contact the insurer if it becomes clear that the original estimate is no longer realistic. A change of job, retirement or caring responsibilities can alter mileage substantially. Updating the policy may change the premium, but it is safer than allowing a material detail to remain wrong.
