Re: How much to add an extra driver on a policy?
Depends mainly on the person you are adding rather than the car itself and there will be quite differing amounts for different Insurers. Age, experience, convictions, accidents, claims, own insurance etc.
In most cases there will be some form of admin fee too. To pluck a figure from the air then £30 for a months cover for an experienced claim free driver on a policy of around £350.
