This doesn't help (actual email quoting from CAA in changing JAR license state):
"As your application has been assessed by Personnel Licensing Department, please note that, should you decide to cancel your application, an assessment fee of £103 will apply as per our current Scheme of Charges. Should the initial cost of the entire application be less than £103, then this fee will be considered as the cancellation charge and you will not be entitled to a refund."
I've already paid £176 to get the change done. Now should I not want to proceed I will get billed an additional £103 for NOT continuing? What did I pay the £176 for then?
You couldn't make it up if you tried. Only in the UK.
