Hello @basinis819
Assuming you have not had any meter changes, plan changes, or tariff rises (usage or daily supply charge) . . .
So you've checked meter readings and nothing seems unusual ?
How do you know this, are the readings similar to past bills ?
There are no hidden charges, at least what I have found.
Your bill has all the information and data on it to tell you where the increase has come from.
How many kwh used for any various readings, the rate for each tariff, that's simple maths to see if accurately calculated.
Then daily supply charge per day x number of billing cycle days.
You need to compare all the above to your last (lower) bill, and see where the increase is from.
Depending on factors like metering (analogue or digital), what plan you are on (single tariff or TOU tariff), just shifting some usage a little into a different tariff level can affect a bill very quickly.
Do you have an electric HWS ?
These can develop a leak which can cause increases in off peak / timed usage increases.
Good luck working it out, the bill comparisons should be your first point to check.
