Nothing but bad service from the moment I joined them. My Bill's have never been accurate and after having a smart meter fitted by them, they billed me £500 for a months usage, it took two months and a lot of stress to get them to rectify it. My smart meter was averaging £40 usage or less per month through summer and I was paying them £87 per month yet when I left they gave me a final bill of £68??? Appauling company and dreadful service. My query sent one month ago has still not been answered. I am now with eon and pay £76 per month and am currently in winter months in credit. I think that sums it up really. Avoid them at all costs.
