With all the carnage in the energy market at the moment, and a lot of smaller companies expected to go to the wall, I'm quite blummen glad I don't have a smart meter right now.
Imagine having a smart meter and being, with say, Accy & Trilby Coal and Oil Power Corp. as your supplier.
The ATCOPC fold, and you're forced to switch supplier. Now, at the best of times this can be fraught, and even with the new meters tales abound of folk having problems...but when your existing supplier has gone bust and there is no one to hand over the necessary serial number and mac address data to the new supplier you're utterly doomed. Doomed, I tells ya!
