Awful, awful company. Smart meter installed since February 2021 and yet I’ve never received any quarterly invoice that wasn’t ‘estimated’! Apparently a communications problem between their billing system and my meter means they can’t read my meter when they need to so I’ve told them to get ithe comms fixed but they’re not interested - just keep telling me that this is the way it works! Furthermore, the in house display unit they gave me has never worked either and guess what, they’re not interested in fixing this either! I’ve asked EDF what’s the point in having a smart meter - a question that they obviously cannot answer. Complaint now with the Ombudsman as EDF decided that my issues with them had reached ‘deadlock’ (incredible really as they haven’t done anything to try to resolve them). Not holding out much hope here though as the chap I spoke to at the Ombudsman’s office was keen to set expectations…. insistent on telling me that I needed to understand that the technology (in this instance the comms link and in house display) weren’t infallible and that sometimes they might be down! I asked what would be an acceptable working rate - 75%, 50%, 25% or, as in my case, 0% - but I think he felt I was being facetious. Will probably end up switching to another supplier.
