Re: I had a smart meter fitted last week
The reduced consumption is temporary. Soon goes back to the previous consumption when the novelty of the meter wears off.
Absolutely true. I picked up a clip-on display half-price at some closing down sale somewhere, and enjoyed watching the graphics on it change whenever the kettle or the telly was on. When the battery ran dry, I couldn't be arsed to replace it. Since I was never in the habit of leaving any light on unnecessarily, or leaving devices on standby, or not switching everything off when I went to bed, the only saving I made was from turning the fridge setting down a little (and leaving a 3-litre bottle of cider in there to act as a cold sink).
Naturally the cold sink needed replacing every Saturday afternoon, but still.
