I'd be very careful with that.
If you are involved in an accident, and they deem you a regular driver but are not listed; they will void the policy.
The reason they quote high is because statistically, as a young driver; you are a high risk. Irrespective of your personal record.
It's part of life; I just refuse to use the companies now that ripped me off as a young driver.
They clamour for your business once you own a house, contents and a couple of cars...
When they ask what they can do to get my business; I tell them to apologise for being such arseholes when I was younger.
Now I just use Shannons.
