Re: estimated net "benefit" of £5.7bn by 2020
@Phil W
Have you any reason to believe that this function on a smart meter is any less accurate than that of a conventional meter?
No but that wasnt the real point. I suspect the read out on the smart meter will be just as accurate as the read out on the conventional meter. However having to regularly check this defeats the time saving the OP claimed.
However there is a side issue - the smart meter can be remotely configured to change the charging rate or the flow measurements etc. This means a malicious party can change things in a way that cant be done with a conventional meter.
