The worst company I have ever had the misfortune to deal with. Joined them in April 2018 and it took them just under to change the smart meters. The gas meter is stuck on one reading and the smart meter reading unit never gives actual meter readings just estimated. Changed back to BG and it has taken them two months to get any sense from Ecotricity. I am a carer of someone with Dementia, which I made clear, when complaing to Ecotricity. Because it is nearly eleven months to sort things out it was/is extremely stressfull because of not knowing how much I owed. I have requested a full and detailed statement, at least six times by email and signed for letter, of how much energy is being used and they have never supplied me with the info. All bills have been estimated. I have now made a complaint to the Energy Ombudsman and I'm waiting for a response. I also communicated by email and phone and they have never replied.
