Re: Smart Meter Mis-selling
My energy company offer me exactly that same functionality , that is to say, I can see a graph predicting my use for the coming month based on the last reading I gave them ( takes 5 mins once a week) and it compares it same month last year.
No need for a smart meter.
They offer the consumer nothing that isn't already available and certainly not "an end to estimated bills" My bill is never estimated because I give them the readings.
It's neither onerous or difficult.
