I moved across from Ovo specifically to go with a green supplier. We are a household of two adults in a three bed detached house. Our bill have been in the region of £1100 per year for the past 3 years, we have been with ecotricity for 6 months and have paid £2000! I have called to raise my concern, after persuading them that it is not due to a fault with our boiler (we are using 3 times more gas than an average house of four!), I sent them photos of my meter as instructed, they have done nothing, and keep chasing for a further £88.0 - I have since changed supplier. For a regulated sector I am staggered they get away with it, I am out of ideas how to get this resolved. For those considering being a little more eco friendly, select a green tarring with another supplier rather than going with ecotricity - it has been a costly mistake for us!
