First Utility are the worst company I have ever had dealings with. As the previous reviews state - they do not answer their phones, I have spent numerous hours on the phone trying to get through, I have sent several emails and had no repsonse and I have even sent a letter and had no reply. I cancelled my application with them within my cooling off period but they continued to go ahead and try to switch my energy and even though I have had confirmation from the supplier I am intending to switch to - First Utility have gone ahead and set up a DD on my account (which I have cancelled). I have now received a letter saying they are going to send me a bill for energy that they are not supplying.
I am so frustrated and angry I have contacted the BBC watchdog team.
All I can say is stay well clear - do not go anywhere near this company. Moneysupermarket and the other switch companies should remove them from their website.
