In our house the gas meter (and leccy) are prepay, and have some basic software on it that interacts with keycards so we know how much credit we have and it shuts off when we run out of credit.
It has crashed on us once before and cut off our gas supply. It compleltly hard locked up and wouldnt respond to any commands.
We called up transco and within a couple of hours someone came out and rebooted the thing and off we went. response was good, engineer friendly and best of all its was free of charge !
If your still having trouble with your meter and supply stuff it might be worth giving them a ring :-)
