Summary of longish saga: in early May we gave in to EDF claiming that our old meters ere past their use-by date, which may well have been true, and got smart gas and electricity meters installed. They provided a Geo Trio II in-home display which worked fine. It gave electricity readings at 30 sec intervals, gas updated every 30 mins, which I gather is normal.
After about 4 weeks it stopped working, but the meter was still giving readings to EDF. Of course their online "energy hub" gives information about 1.5 days in arrears, which is not much use to the consumer try to save money, e.g. to take advantage of these schemes to get paid for turning off expensive appliances at times of maximum demand. I complained and EDF eventually sent a technician. He found the comms module in the meter was faulty, replaced it, and the in-home display worked again. Result.
About a month later it stopped working again. We have had two more visits by technicians who fiddled around and provided 2 more in-home displays, as if that was the fault, which it obviously was not. Today on the phone the EDF customer assistant tried to get the fourth one working (Chameleon TYPE 2). But this also failed to connect properly: for electricity it shows "Supply disconnected" which is obviously stupid, for gas there is no information at all. It is obvious that the comms module in the electricity meter has failed again. She refused to get anyone else to fix it or to refer it to higher authority within EDF and said EDF will send us a letter saying this dispute is unresolved. This seems pretty stupid to me.
We could, I suppose, just change suppliers to a more competent company as tariffs are all much the same these days, but suspect that another company would not agree to fix a defective installation that has been simply abandoned by EDF.
Our best option appears to be to get the Energy Ombudsman involved, as their website says that suppliers are required to provide a working in-home display and if it fails in the first year to repair or replace it. This seems pretty clear cut - but does anyone else have experience of getting the Energy Ombudsman involved in such matters.
