Hi Mark,I've also just been shifted from quarterly onto monthly billing with no reason given.Similarly, with my 12 month Solar Savers contract coming to an end recently, I was told I was being shifted to the Solar Value contract which of course pays less FIT. Of course we can shift plans, but to assume that I wanted the Solar Value plan and then make me wait for the appropriate date to shift my plan back to Solar Savers seemed like a sly attempt to reduce my FIT even further.
