What is the cheapest insurance option for a new driver?

Mark,

As you have noticed, new drivers car insurance is very high because of their lack of driving experience. If your parents will be driving the car more often, then you can become a named driver on their insurance policy and with some selected insurance companies, you will build your no claims bonus which will entitle you to a discount when you decide to take insurance in your own name with that same company afterwards. The benefits of this is that the insurance quote will be much cheaper.

If on the other hand, you decide to get insurance in your own name, the insurance premiums will be quite high to start off with. However, if you've been good and have not made any claims, you will get 1 year full no claims discount and this will bring your next quote down significantly. You will also be able to change companies and use that no claims discount elsewhere which you cannot do when you're a named driver.

I'd say take your own policy and drive carefully and in the long term you will enjoy great insurance discounts.
