I recently called Origin Energy to renew my electricity plan and the best discount they could provide (without direct debit) was 20% off pay.
I told them I was gonna move to AGL because even though their rates were a little higher, the AGL discount (18%) combined with a free month of electricity was still cheaper, and they said the best they could offer was 20% off (and they couldn't offer a month free).
The difference isn't big but searching Ozbargain forums, a few users have said they have gotten like 30% discounts or something.
So the question is, how do you obtain such discounts? Like are there any specific words that should be mentioned, or like switching back during cooling off periods?
Responses can be for other utilities beside electricity!
Edit: I should add I considered the rates and AGL was cheaper, also this is for NSW.
Better discount is not equal to a better price. You should be looking at the supply and kw/h prices of each provider individually.
