Very poor customer service and massively over estimation of annual gas usage. EDF estimated usage to be 18,227 kWh when actual and historic usage between is 6,000 and 7,000 kWh. EDF gave me a £217 over payment credit in Nov 2023 and recently advised that they needed to increase my standing order from £134 to over £190 to clear my outstanding debt of just over £100. I used their online smart meter readings to try and demonstrate that estimate was grossly inflated but the only reply I got was that we have conducted a thorough review of you account and my payments were insufficient!!!
