Very high electricity bill




Ever since moving house my electricity bill has nearly doubled. From $120 to $220 (after discount) per month Only 2 adults live at the premises, whilst the previous place of residence had gas cooking and hot water, i wouldn't think it would equate to an extra 100 dollars per month in billings.


There is a granny flat out the back and appears to be metered separately in the same power meter housing.


But am not sure as to why the billing is so high. As the bill conpares our household to that of a family of 6+ people.


Thank you for any assistance.

Hey Ausmetal,


Welcome to the AGL Community!


If you feel that your monthly electricity bills for your new property are on average considerably higher than your monthly electricity and gas bills for your previous property combined, there are a few different things that you can do! If you have a basic electricity meter on site, we'd recommend that you start by comparing the reading currently on your meter against the reading on your bill to ensure that your meter reading is accurate. If you have a smart meter, we'd recommend that you log in online here to review your usage data since moving in which may shed some light on when you're using the most power, and subsequently, which appliance(s) is using the most power.


If you feel you need further assistance, you're welcome to get in touch with our web chat team here.


Kind regards,

Suspected faulty thermostat in hot water system, so the hot water system keeps heating water all day without stopping.  This is yet to be verified by an electrician / plumber.  Backstory is as follows.

Understanding that it is winter and electricity usage creeps up during these months.  But according to the AGL app and on the smart meter we're using 30.00+ kWh per day.  As stated previously, we don't run hot water washes, or have a heater.  Only a split system to heat a room maybe once a fortnight.  Two adults occupy the premises and we both work full time.  Anyways, how I have come to the conclusion above is by the following.

Turning off the hot water system overnight has resulted in a drop from 1.10kWh consumption per hour to 0.26kWh per hour.  Even watching the smart power meter in the power box and turning off the hot water system is resulting in a 75% drop in power consumption coming into the power box.

Nothing as of yet,

I am renting and in West Sydney.  The electrician came out and inspected the hot water system, noticed a leak from the soffit above.  There is a water/rust mark where the water was dripping down into the electrical box of the hot water system.  He did some tests and reset the thermostat in the hot water system.  This was a week and a half ago and power consumption hasn't changed.  Electrician and myself have relayed this information back to the real estate property manager, but have heard no response.

I am a day from the end of the current bill cycle for the month and the current bill sits at $361.00 that's for the month, not a quarter.

I suspect the thermostat is broken and heats water at all times.  Looking at the smart meter mobile app between the hours 12am and 6am power consumption sits at around 45cents to 50cents per hour whilst my partner and I are asleep.  I switched the hot water system off over night and power consumption drops to 5cents an hour.

Using that information and multiply the 45cents per hour by 24 = $10.80 per day.  Multiply $10.80 by 30 for the month = $324.00.  That's just for a hot water system, which to me is quite insane.

For reference, I used to live in Far North Queensland, granted, I lived by myself.  But I had a pool pump running and air conditioning, my bill quarterly was between $300-$400 mark, again, that was for the quarter; not a month.

Anyways, is your billing cycle monthly or quarterly?  Because $450 per month is extreme for a monthly bill cycle.

Sorry for the long reply, I figured it best to give you all the information I have on the matter and it's on record here.
