I have just had a phone call from someone at EDF to tell me that was a problem with our smart meter. She’s phoning back in a couple of hours because I told her I had no authority to authorise anything.
I then rang EDF on a different phone to check it was legitimate.
It is so how daft do I feel? Why do I think everything is a scam?
To OP - sorry I don’t know the answer to your query to how you can get a neutral reading.
