How do they help you save bills? Unless your going to look at the meter every time you turn something on and then decide to turn it off again….but then you can do the same by using a simple current clamp meter with a readout in the house (which we have), we haven’t had an estimated bill for years as we send the reading in at each time they ask, not a biggy.
They want you to have a smart meter not for your cost savings but so in the future they will be able to use variable charge rates at high and low periods of demand.
Having said that unfortunately our gas meter has a fault which has stopped it recording usage so requires replacing and I have notified the suppliers of this and they say they will get around to fitting new meter (and it will have to be Smart) when they can, I don’t mind as it was first reported last September and since then officially we have used no gas over the Winter, I think they are not too bothered as our original supplier was one that went bust just before Christmas.
