Shock horror - there's no refund for a full licence and they want the princely sum of £35 for the privilege of making the change

If I cancel the policy to then take out a classic bike policy I get bugger all back, unless I take the policy out with Carole Nash, in which case I get £50 back. I started the policy in March this year and paid £170+.
They had the cheek to tell me the policy price was £80 odd and the rest was broker fees and legal protection. So more than the cost of the insurance policy.
I told them to forget the conversation as it was in my interest to carry on as we stand.
This is not on really. I'm going to let the policy lapse then tell them to stuff it in future and look around for a classic bike policy. What sort of quotes can I expect?
