Past three years I've been the main driver and my OH a second driver. It was done this way as he was a learner when we got the car and then we left it as I was (a) female and (b) had been driving 10+ years. Today I plugged in all the details into a comparison site and got quotes £200-£300 cheaper with him as the main driver. Any idea why? Especially as I have 10 years more driving experience and he had an at fault claim last year.
