Add Someone Else To The Insurance Policy
It needn't be someone older or more experienced than you - play around with adding your partner or parent to the policy - and you might be pleasantly surprised. Things that are taken into account are the other person's job, any driving convictions (don't bother if they have any!) and the age of their license.
However if you are the car owner, don't even consider "fronting" - whereby you are the main driver but you put the policy in someone else's name (usually a parent) and you are a named driver. It's illegal, you may get a fine or a criminal conviction and it's likely your insurance will be void.
With this in mind however, try playing around with adding and removing members of your family - it's easy enough on the insurance comparison sites - and you might be pleasantly surprised what differences it can make to your premium.
