For an insurance provider, it’s all about assessing and pricing risk. They know that the student age group is statistically more likely to make a claim than older drivers.
We know this isn’t necessarily your fault, but rather the result of your circumstances. You’re likely to have not been driving for long and that, unfortunately, statistically speaking, means more accidents. Additionally, as you’ve not been driving long, it might also be that you’ve had no opportunity to build up any no claims discount which could help you reduce your car insurance premiums at each renewal.
Finally, another reason for higher costs as a student may be the area you live in. For many students, particularly in larger cities, the post codes they live in tend to have higher crime rates. The area of the country will have a big impact too. Some students in London can expect to pay more than twice the amount that those in some parts of Scotland do.
