After 12 years we had our Heatwise tariff discontinued at the beginning of August. We had an E10 smart meter and display fitted 27th July. The meter showed when we were going on the cheaper tariff ie. mid afternoon, evening etc. Now E.ON inform me I am on E7 tariff. I cant make out if I am still getting the cheaper rate in the afternoon and evening or not. They tell me E10 tariff is not available. If so, why are so many people on this site on E10. Why did they fit a E10 meter and display. Do I ignore the information shown. I feel as though I have been really stitched up and can’t get any satisfactory answers, I’m almost made to feel like a stupid pensioner!
