Not great at the start. Had to keep contacting them because they insisted on using predictions despite me sending them meter readings. They didn't agree with a reading so I then had to send proof which I suppose is fair, but I think they only didn't agree because of their prediction. A lot of back and forth with relatively unhelpful people. They keep contacting me to install a smart meter which I can't do as i'm renting. I've asked them to stop but they keep contacting me for it. Otherwise the service is no different from any other provider... would say try someone else.
