I joined the Sunday Saver Scheme and kept detailed meter readings, including smartphone photos. Free electricity amounted to 98.35 kW’s over 4 Sundays and Xmas day totalling £24.16. I have been rebated only £14.54. I have made detailed complaint via email and received inadequate and incorrect information. I now intend to raise the issue with Energy Ombudsman. It’s a small amount, but annoying. I suspect EDF lack the systems to measure precisely free energy so millions of customers may be affected. Just wondering if anybody here joined the scheme, kept their own records and have been short-changed.
