Is it possible in a domestic premises to use 35KW of electricity per day? I ask because I've just had a bill from EDF saying that I used 3300KW of electricity from October to February (19 weeks). I've noticed that they think I’m using between 15KW and 35KW per day. When I only use about 60KW per week, the 'smart' meter is recording the amount of electricity correctly as I can see on the meter screen. However, it's sending erroneous information to EDF. On Friday 26th Feb the customer advisor I spoke to said that my electricity meter was reading 19671, yet on the meter screen it was reading 7233. I've noticed that the mobile connection is very weak at about -85dBm. EDF must be getting more noise than signal. It's very worrying when EDF says I owe £500 for electricity used. I read the energy meters every week. For the period from October to February, I owe about £170.
