My experience so far with Good Energy has been anything but good. I recently moved into a house which has solar panels with which the previous owners had set up their feed in tariff with Good Energy. I had been with Octopus Energy in my previous house so wished set up the tariff with them. Unfortunately, I was informed that to do so I would have to first change the registration of the panels to myself with the existing supplier, who was, unfortunately, Good Energy. My first contact with them was with a young man who quite abruptly told me that the only way to make the amendment would be to send in a mailed application and got me off the phone as quickly as he possibly could (rude and professional). I duly filled in the form, attached the relevant paperwork and popped them all in the post (this was around 17th September). A month later I had not heard anything, so I called as was told that the previous month the whole company was busy with some sort of audit so nothing else would be processed - sorry but you'll just have to wait, they couldn't even tell me if the documents had been recieved. Three weeks later I phoned back and was told that the documents had been received on the 23rd September (why the previous adviser couldn't tell me this I am not sure), and that they would be processed shortly. Two weeks after that I called again and this time was told that they would try and get it done for me on the day (this is now mid-November). On the 29th November I received an email, apparently the documents they requested did not contain the correct information for them to complete the transfer, so a massive waste of time. The email I received requested that I send alternate evidence of the transfer of the panels and suggested email testimony from the previous owners of the house. I then contacted the previous owners who advised that they already had done that before they moved and forwarded me the email string. Again, why this email string was not in their records already for the address I do not know. I received the email requesting this new information on he 29th November and I replied to it the next day, on the 5th December I wrote a follow up email requesting an update, it is now the 7th December (a full three months since I moved to the property) and I am still awaiting a reply. In summary: Avoid this shambles of an "organisation" like the plague.
