Ok, will do 

FYI

Powergen have already suggested this, but I guess this gets them out of a sticky situation. I live on a newish estate and so we've all probably got the same meters in place. I'm reluctant to do anything at the moment until I've exhausted all the avenues in order to get a new supplier who will take the Economy 10 Meter and provide a good tariff. NPower said they would but thats it, and they've not got the best record.

Thanks again
