I really don't understand the reticence to have a smart meter, I'm yet to see a convincing argument against having one. What reports have you heard on reliability Lurker? The only issues I've heard about are relating to it taking some time to migrate if you move suppliers, and all that means is the smart functionality stops reporting back your meter usage and you go back to manual reading for a while. If that does happen, then you're in no worse position than you are right now, and the flow of electricity into your house doesn't stop, so apart from a bit of a pain to make a phone call or two to sort out there really is no issue.
I've heard people talk about data concerns and cyber attacks. Well if someone can tell anything meaningful from the electricity usage in my house then fair play to them, and it isn't attached to my home network in any way, so there's no risk there.
I'm more than happy to listen to any argument otherwise, but tbh all I've heard so far are baseless scaremongering with no foundation. Happy to be convinced otherwise though.
What I do know is smart metering is vital to better understanding people's usage, to help regulate the amount of energy we need in this country, when we need it, and who needs it at any given time. Data is King/Queen, and the MWHH initiative that came in recently goes even further to giving us that visibility and contol over availability.
I've had my SM for about 5 years and apart from when I swapped over from Octopus from my previous supplier, when it took a couple of months and a few phone calls to get the SM & in house display to work properly with Octopus, I've not given it a single seconds thought or had a single second of issue.
