It would be easy to agree.
We have our everyday home with AGL for electricity and a local supplier for bottled gas for HW and stove.
Our other, part-time place has Origin for electricity and also town reticulated gas.
Sometime previously both moved us onto discounted rates (plans in their speak), simply for paying on time. Lots of anger with both at the time as we always paid in time.
When you compare the charges for either the total bottom line bill for the same usage is much the same.
While AGL have a higher feedin for solar 20c vs Origin 17c they are offset by similar differences in usage and daily connection charges. Both charge a daily solar metering charge, a rort in any form given the smart meters save the monthly or quarterly meter readers cost.
We will be shopping around after our next bills, which will have the first full quarter for each with PV benefits.
