Ovo energy are absolutely bloody useless I’ve been with them for 8 months now and I have had to phone at least once a month sometimes twice to complain about their service bills that take 15 days to arrive after I’ve sent in meter readings meanwhile they send you letters and txts demanding you pay what you owe how can anything if you haven’t received your bill and also they keep sending me letters to have a smart Meter which I have told them on numerous occasions that I will not have one cos they don’t bloody work properly so if anybody is thinking of joining ovo energy I’d advise them not to i has to give them one star before I could write this review but to be honest they don’t even deserve one star they deserve zero stars
