To estimate your mileage:
Work out how many miles you drive every day or week, then add them up to work out your annual use
Or check your MOT certificate or car service record, which will show how many miles you’ve driven. Use this as a basis to calculate your future mileage.
Mileage can affect your car insurance premium – the more you drive, the more of a risk providers consider you to be. Be as accurate as you can when you estimate your mileage. If you underestimate, it could invalidate your policy. If you overestimate, you could end up paying more than you need to.
