I left Good Energy last December mainly because every time I needed to pay them there was a problem. Their systems were clearly terrible. Having got rid of them I thought all was well and good but NO. 10 months later they have just asked me to pay them £80 in, apparently, unpaid, charges that I knew nothing about. The bills I asked them to send out in response to this were so opaque that the person I spoke to - poor woman, she was very patient and nice - had to ask a supervisor what they meant. I still have no real idea if what I have paid is what I really used. Avoid
