We have had 2x 1500+ electricity bills and a $1000 one. We have had 2 electricians come around and say they can't see any reason why our bills are so high. We are 2 adults and a 2 year old, we don't own a dryer, we hardly run the aircon, the only thing we have is an extra fridge but there is no reason why that should make it so high. Origin (our provider) has a high bill investigation service we have only just found this out, so they are currently 'investigating' our most recent bill. Unfortunately they are hopelessly inept and I'm not sure exactly what form this investigation takes. I feel your pain! I know the rates have gone up but this is ridiculous. hope you can find the problem.
