"If you’ve decided to bring a car to uni with you, it’s worth thinking about how much you’re likely to use it. If you live on campus and won’t be driving much, you might be able to save money on your car insurance with a pay-per-mile policy.
But if you only use your car for visiting home, you might be better off getting temporary insurance for just the duration of those journeys. But be careful - you'll need to give your car a Statutory Off-Road Notification (SORN) when you're not using it."
