Energy Bill Guide | Understanding Your Gas & Electricity Bill

Manage Energy Bills

Energy bills are part of life. While there are ways to lower your energy bills, through finding a better deal with a new electricity or gas provider, or using less energy, they will always be a necessary payment. Find out more information about receiving, paying, and finding financial help with your energy bills by reading below.

Receiving Your Energy Bill

Energy Bills

Energy bills usually come every three months, when your meter gets read by your energy provider.

However, you could have the option to pay your bills weekly, every two weeks, or monthly, depending on your provider.

Traditionally, electricity bills and gas bills are sent through the post. However, as the cost of paper mail rises, more energy retailers are opting for e-billing.

Choosing e-billing can be a cheaper and more convenient option for energy customers, and help save the planet by reducing the use of paper. E-bills are also less likely to get lost or go missing and are updated automatically in your customer portal.

Most of the big energy retailers, and some of the smaller ones, still offer bills by post. However, many energy companies are introducing incentives to push their customers to opt for e-billing. Incentives include offering steeper discounts for customers who choose e-billing, special tariffs or charges of up to $3 for bills sent by post.

How to Read an Energy Bill

Energy bills look different depending on your energy provider. However, all electricity and gas bills generally contain the same basic information*, making it easy to read your bill once you know what to look for.

Electricity bills & gas bills will have the following information:

What Makes Up an Energy Bill


CONTACT INFORMATION: The first and last name of the account holder, additional names on the bill, your address. There will also be the contact information listed for your energy supplier as well as your energy distributor.


ACCOUNT INFORMATION: Your energy account number, tax invoice number and the name of your energy plan for which you are being billed for.


BILLING PERIOD: Traditionally done quarterly but more and more providers are giving customers the option to receive their bills more frequently to avoid bill shock.


ENERGY METER INFO: Your electricity and gas bill will include your meter number (NMI). This should match the number on the meter connected to your house. The meter reading is used to calculate your bill in kWh for electricity and MJ for gas. If your bill is based on an estimate then it will be stated on your bill.


TOTAL AMOUNT OWED: Credits received or outstanding payments, and when the bill is due. The dates for the billing period will also be listed.


EXACT USAGE & SUPPLY CHARGES: Your usage will be charged as cents per kWh for electricity bills. Your usage for gas bills will be charged as cents per MJ. Both types of energy bills include a daily supply charge (cents per day) for having energy supplied to the property.


ADDITIONAL CHARGES: GreenPower subscriptions, or addons you have purchased with your energy plan.


REBATES & DISCOUNTS: Such as solar feed-in-tariffs or energy concessions

Some providers might also offer insights into your energy usage.

This could include information comparing your energy usage from the same period of time last year to your current bill, information comparing your energy usage to the average bill of other homes nearby, or whether you might save more by switching to a different plan with your provider.

It’s important to remember that many smaller energy retailers are doing away with traditional methods of purchasing and paying for the energy you use, and every provider is different. Pay-as-you-go, wholesale, or other methods of paying for and receiving energy are becoming increasingly popular.

Check your household’s energy retailer for more information about their billing and payment methods.

Energy Bill Examples

Now that you have learned how to read your bill, it's time we look at an example. Below, we will show an example of a gas bill and an electricity bill, so you can have more detailed information on both.

It is important to note that even if you have gas and electricity at your property with the same company, you will receive a separate bill for each.

The main difference you'll see when reading your gas bill is that your electricity is counted in kWh and your gas is counted in Mj. You will also likely have a different distributor listed on your bill for gas and electricity. However, for the most part, the bills will be pretty much the same.

Electricity Bill Example

Here is an example of an electricity bill using an Origin Energy sample bill. Although this electricity bill example is for Origin Energy, most providers have the same basic layout in order to help you read the electricity bill more easily.

Gas Bill Example

Now that you've learned how to read an electricity bill and a gas bill here is an example gas bill from Origin Energy.

While this gas bill example is specific to one energy provider, most of the information found on this bill is the same as other energy providers in Australia.

Gas bill page 1 Gas bill page 2 Gas bill page 3
Example of how to read your gas bill

It’s important to remember that many smaller gas retailers are doing away with traditional methods of purchasing and paying for the energy you use, and every provider is different.

Pay-as-you-go, wholesale, or other methods of paying for and receiving energy are becoming increasingly popular. Check your bills for more information about your providers billing and payment methods.

How Can I View My Energy Bill?

Yellow Laptop

If you want to have a look at your energy bill, most companies offer online platforms and smartphone apps where you can manage your energy account.

To view your bill online, navigate to your supplier's website and find the Account Login or My Account button. From there you will be prompted to energy your login information which is typically your email address or account number as the username, and a custom password you have created.

If you have never made an account, you can typically register for one on the login page.

If you don't have an online account or do not want to use the online account to view your bill, you can always call your energy provider and they will be able to tell you how much you owe and how much energy you have used.

Lastly, if you have a smart meter, some smart meters will show you how much energy you have used in dollars.

How to Pay Your Energy Bill

There are a number of ways to pay your energy bill. Each energy retailer is different, so it’s best to check with your provider to see what methods they have to pay your bill.

Common bill payment methods include:

  • Online Bill Payment
  • Mailing in bill payments
  • PostBillPay
  • Bpay
  • Paying over the phone
  • Direct Debit payments
  • Centrelink Payments

Below we explain each of these bill payment methods in more detail:

Bill Payment Online

You can make a bill payment online with a credit or debit card either through a secure link or on your energy retailers My Account page when you receive your electricity bill or gas bill.

This method is different from a direct debit because you pay the bill upon receipt.

Paying a Bill by Post

You can pay your bill by mail by sending in a cheque or money order to the address your energy retailer provides


PostBill Pay is a service offered by Auspost that allows you to pay your electric bills or gas bills at any post office, over the phone by dialling 13 18 16, through the AusPost app, or online at


BPay is an online bill payment platform that is backed by over 150 Australian banks. To pay your electricity bill using Bpay, your energy provider will give you a unique reference number or account number, along with their BPay Biller Code on your bill or invoice. You can use the BPay Biller Code to pay your electricity bill through your online bank.

Pay Your Bill Over the Phone

You can usually pay your bill over the phone unless your energy supplier is online only. Your energy provider might have a secure phone number you can call to pay your bill over the phone with either a credit or debit card, often available 24/7.

Direct Debit Payments

When you sign up for your energy account you can set up a direct debit or credit which gives your energy retailer permission to directly take the amount you owe on your bill from your account automatically. Signing up for direct debit bill payments tends to allow you access to cheaper energy deals.

Centrelink users can opt to have their energy bills be paid directly from their Centrelink account.

There is not a single bill payment method that is better than others, but as we mentioned before, some retailers offer conditional discounts towards your energy bill if you pay on time and/or opt for direct debit.

If you set up a direct debit, then you won’t need to worry about paying your bill on time as long as your account has the funds for it. You might also get an extra discount on your bill.

Having Trouble Paying Your Energy Bills?

According to the National Retail Energy Laws, your gas or electricity retailer must assist you if you’re having difficulty paying your bills. If you know you might have difficulty paying, contact your energy provider immediately to find out what assistance is available to you.

Most retailers have different options available to help those in need of assistance with paying their bills and disconnecting your energy supply will only be used as a last resort.

Some solutions for paying your bills include:

  • PAYMENT EXTENSIONS: If this is a one-off problem, for whatever reason, ask your retailer for more time to pay your bill
  • PAYMENT PLANS: If you are behind on your bills, or one was exceptionally high, you might qualify for a payment plan to pay your bills in instalments. If this happens, you and your provider will discuss what you owe and how much you can pay, how often you can pay it, and how much energy you use. However, if you fall behind on a payment plan your energy provider might disconnect your energy supply.
  • HARDSHIP PROGRAMS: These go beyond a payment plan to include assistance in lowering your energy bill, switching to a cheaper plan, offering financial counselling, and signing up for concessions and rebates (including Centrelink)
  • GOVERNMENT CONCESSIONS & REBATES: If you are unable to work or a low-income earner, have a medical condition or are on a pension, you could be eligible for financial assistance from the government. Your retailer will be able to help you find out which rebates or concessions you are eligible for.

Financial CounsellingFinancial counsellors in Australia are free to talk to if you find yourself in a time of hardship. These independent advisors will help you figure out your options, and might be able to help you speak to your energy provider. To get in touch with a financial counsellor contact 1800 007 007

Can My Energy Provider Shut off My Electricity?

An energy retailer must go through certain steps before disconnecting your property due to a lack of payment.

  • Before shutting off your energy, your energy retailer will need to:
  • Send you a reminder to pay any outstanding balance owed
  • Send a disconnection warning, letting you know your property will be disconnected from its energy supply
  • Attempt to speak with you before disconnection (and offer solutions)

If your energy is being disconnected, retailers have certain guidelines they must follow as to when your energy will be disconnected.

Under the National Retail Energy Law, energy providers cannot disconnect you on:

  • business days before 8am and after 3pm
  • the day before or the day of a public holiday
  • between December 20th and December 31st
  • during extreme weather conditions

They cannot disconnect you if you already reached a payment agreement and the debt amount is less than AER stipulated amount.

Under certain circumstances, you might need to get in touch with your state’s Ombudsmen.

You should contact your Ombudsmen if you and your retailer cannot agree on a payment plan or you cannot afford the payment plan your retailer is asking for if your retailer will not give you a payment plan, or if your energy has been disconnected unfairly or by mistake.

Domestic ViolenceMany energy companies have a domestic violence policy. If your ability to pay your energy bill, or anything else relating to your energy usage, is affected by domestic violence your energy retailer might offer confidential help during these circumstances.

What If My Energy Bill is Wrong?

Meter Reading

Energy bills usually come when your meter gets read by your energy distributor.

However, sometimes your electricity bills or gas bills are wrong.

If your energy bill is incorrect, it's usually because the energy provider could not read your meter. This could be due to a broken meter or that your meter was difficult to access.

If this is the case, you will be given an estimated bill instead of a bill that reflects your exact usage. You may have an “E” next to your usage charges on your bill which typically indicate that it’s an estimated bill.

When your energy retailer gives you an estimated bill, they generally look at:

  1. Your bill for the same period of time last year
  2. Your usage history
  3. A bill for a similar customer

If you have received an estimated bill, simply contact your energy provider and give them a meter reading. This will give them your exact usage and that can update your bill accordingly.

If you have a smart meter or the option of SmoothPay, your bills might come more often than every three months.

Some energy providers let you pay the same amount every week/fortnight/month, and will give you the remaining total for your quarterly energy bill when your meter is read.

In this case, if you overpaid on your smaller estimates you will have a reduced bill or credit towards your next bill. If you didn’t pay enough, then you’ll need to pay the difference.

It’s always important to remember that if you cannot resolve a billing dispute with your energy provider, you can contact your state’s energy Ombudsmen to escalate the problem.

How Much Should My Bill Cost?

There is no correct answer to how much your energy bill should cost as it depends on multiple factors specific to each persons individual situation.

However, the nationwide average for electricity bills in Australia is $1,645 / year. This number can be higher or lower depending on your state and your individual consumption.

If you have more questions about the average energy bill in your state or for a household of your size, you can take a look at our detailed report on the average annual electricity bill in Australia. Here you will see a state by state breakdown for average electricity bills in Australia between 2020-2021. (The 2022 report will be published in 2023.)

My Energy Bill is Too High

If your energy provider sends you a bill and the amount is too high for the energy you used, then your provider overcharged you.

If this happens, one of two things can be done to resolve it:

 If your energy provider overcharged you by $50 or more, then you can request they either take the overcharged amount off your next bill or send you a refund for the amount.

 If your energy provider overcharged you by less than $50, then the overcharged amount will go towards your next bill.

My Energy Bill is Too Low

If your energy provider sends you a bill that is too low for the energy you used, then your provider undercharged you.

If this happens, there could be a number of reasons why and more often than not your next bill will be higher to reflect the amount you weren’t charged for:

 If your retailer undercharged you, and it’s their fault (likely due to a computer error or billing system), then you will only owe them the difference for the last nine months. For example: If your bills were $10 lower than they should be, every month for one year, you only owe $90 in total, not $120.

 If your retailer undercharged you due to issues with reading your meter and they needed to estimate, then you will owe everything they undercharged you for, for the total amount of time you were undercharged. For example: If your bills were $10 lower than they should be, every month for one year, you would owe all $120 because it was not an error on the part of the energy retailer.

If you were undercharged on your bills, you won’t need to pay back everything at once. Depending on how long you were undercharged for will affect how long you have to pay back what you owe.

 If you were undercharged for 12 months or more, you will have 12 months to pay back what you owe. If, for example, your energy provider undercharged you for 13 months, you would still have 12 months to pay it back.

 If you were undercharged for less than 12 months, then however many months they undercharged you is how many months you have to pay back what you owe. If you were undercharged for six months, you’d have six months to pay it back.

Ways to Lower Your Energy Bill

Energy bills are a big expense, and costs only seem to be increasing. Luckily your energy bill can help you learn more about your household’s energy usage, and ways you could lower your energy costs.

See our detailed guide on how to reduce your electric bills, where we cover all of the available methods to save on your bills.

 Tariff type: You can change your tariff to a time-of-use tariff to save you money by paying less when you use enrgy during off-peak hours. Likewise, adding a controlled load tariff to a large appliance like a pool heater or electric boiler, can save you on your annual energy costs as well.

 Energy usage: Look into energy saving measures if your bills seem abnormally high. These could range from unplugging appliances when not in use, to adding window treatments and other home renovations to increase energy efficiency.

 Switching plans or providers: If you’ve never compared energy providers before, you might be getting charged the highest rate at the default market offer. Switching providers is quite easy. Contact our Selectra representatives to see how you could save by switching tariffs.

Energy Billing FAQ

How is My Electricity Bill Calculated in Australia?

Calculating your electricity bill: Fixed electricity connection fee
+ Usage charges (total kWh used x $/1kwH usage rate)

Most providers charge a monthly or quarterly fixed connection fee and then add on your usage charges (per kWh of electricity that you actually use). Some companies also charge an initial connection fee. It is worth asking about set period discounts that are offered by many power companies.

How Can I Pay My Electricity Bills in Australia?

With most providers, a range of payment options are available such as credit card payment, debit card payment, automatic direct debit, or paying at the post office in person or via the telephone.

Electricity bills in Australia are generally charged on a quarterly basis (i.e. four times a year, once every three months), though some plans allow for monthly billing if you have a smart meter installed at your home.

Not all residences in Australia are on the same quarterly (90-day) billing cycle, so when you move into your home it could take anywhere from 10 to 100 days for your first electricity bill to arrive in the mail. When it does, however, you will see the dates for which you are being billed clearly indicated on the bill, as well as the charges involved.

When it comes to paying your electricity bill in Australia, you will generally have several options (depending on your provider):

  • Credit card (online/telephone)
  • Direct debit (automatic withdrawals from your bank account or credit card)
  • BPAY - another way to pay directly from your bank or credit union account
  • At the post office (Australia Post) - you can pay over the counter either in cash or by debit or credit card. You can also pay over the phone.

Many providers also have the option for you to set up an account page online with them as well to manage payments and services. Some also have apps if you prefer that method.

Pay your electricity bills on time! If you forget to pay your electricity bills on time, you may incur additional late fees!

We all lead busy lives and forget things sometimes, so setting up a direct debit from your account or credit card (or similar automatic payment) is a good way to avoid those pesky late fees that no one wants to pay.

How Can I Save Money on My Electricity Bills in Australia?

The cost-of-living in Australia is quite high these days, particularly in cities like Melbourne and Sydney. Electricity in Australia is quite expensive in comparison to many other countries, with the average Australian family spending nearly $1600 annually (2021) and costs projected to continue to rise in the coming years. For this reason, many people in Australia look for ways to reduce their electricity bills wherever possible as a way to save money and bolster their overall household budget.

There are essentially two basic ways to save money on your electricity bills in Australia:

  1. Reducing electricity usage - electricity companies in Australia generally levy usage charges (kWh) on top of your fixed monthly connection fee. This means that anything you can do to reduce the amount of electricity that you use will help to reduce your electricity bills.
  2. Switching to a new electricity provider - in states/regions of Australia where energy markets have been deregulated, you can choose your preferred electricity provider. Market competition between different companies means that it can be worth your while to shop around for cheaper energy plans (e.g. better fixed monthly connection fees or better usage charges…or ideally both!).

Here at Selectra we understand that choosing electricity providers in Australia, especially if you are new to the area or the country, can be overwhelming. We're here to help! Feel free to contact us at any time for a free consultation on which energy providers in Australia could best suit your needs (and your budget!).
