The frozen north
I can tell you that in the northern region of England, at least, repairing the existing dumb metering systems is playing second fiddle to rolling out their replacements. A (planned) power outage resulted in my Economy 7 timer being out by around 8 hours, meaning that the water and storage heaters were operating at an economically unatrractive time of day.
Putting the clock right is a two minute job, but after six months and a succession of cancelled appointments - because the meter repair team was reassigned to smart meter installations - it still wasn't fixed. I moved house and it still wasn't fixed 6 months after the new residents moved in.
And at the time, they were still installing the original smart meters, knowing they'd need either upgrading or replacing shortly after.
Madness.
