As soon as you can get your provisional, have a shop around and find out what insurance companies will accept you as a learner, and how much it will cost. bushbaby's right, some policies will let you accrue NCB, some won't. So obviously you would need to be on a policy that will get you some insurance history and NCB. Even if you never drive the car, being on the insurance and proving history will help the cost of your own insurance when you need it. Don't forget if there is a big gap, it won't count, so there is no point in doing this ofr a year then nothing for five.
