Thanks Andrew..very interesting.
So…. when you classify as e7 do you mean they supply 7 hrs per day OR that they apply their e7 rate to e10 so will indeed supply 10 hrs daily?
We are stuck with Eon for now until our recently replaced (by Eon) old e10 metres (which meant we had 2mpan numbers ) appears on the national darabase with its new solitary number. Can take up to 3 months. One down, two to go.
Thanks for your help
