Their tariff prices are significantly higher than competitors. Absolutely abysmal scamming company. Consistently underestimated my energy bill (estimating 3x lower than what it actually was), then after 6 months stuck me with a bill for £1100. After talking to the representatives twice and explaining that 1) it is extremely sneaky that they do this. 2) I would pay this off but would need to pay it off with a payment plan, to which they agreed. I was promised communication back, of which there was none, two weeks later I start receiving calls from a collection company...Avoid Ecotricity. Disgusting, terrible company.
