The technician came and readied the system but then said you were all out of meters so he couldn’t put one in. He said I needed to contact my supplier. This is not acceptable

Installation of a new smart metre
Your engineer was polite and friendly and went about his work quickly and efficiently. When he finished installing the smart metre he took the trouble to explain everything to me which I found very helpful.

Utterly dreadful, amateur incompetance.
My wife took a day off work for the appointment, only for your engineer to turn up at Mom's with just an Electricity meter and NO Gas meter.
As she is Self Employed she will now have to lose another day's wages for you to come back and fit the Electricity meter you should have fitted at the same time.
The engineer knew he didn't have the right equipment, but didn't bother to call and re-arrange for a time when he had everything he needed instead of just messing us around.
You have also fitted a completely different meter to what we have, despite us both moving to Ecotricity at the same time.
At least this bloke didn't leave a mess like we were left to clean up when he did ours.
Incompetent, amateur, dreadful service, I wish I'd never agreed to have Smart meters.
