How much would a new driver expect to pay for their car insurance (UK)?

I'm 16 and will soon begin driving lessons, and every company I go to online to find a quote asks for my name and address, and until I need the insurance i'm not going to enter them.

Does anyone have an idea how much a 17 year old would expect to insure a first car (something small like a Vauxhall Corso, Renault Clio et al)?
