Some of the Owners received their electricity accounts yesterday from Energy Australia and I was astounded that our personal account for 3 months went from $323 to $1,300. How best do we challenge this or does it seem OK?
Double check that the bills were based on actual readings and not a “guesstimate”. Everyone is expecting higher bills and some energy providers may be taking advantage of that to save money of accurate readings (with the intention of levelling them out later).
