Understand your bill

Each year, the WA State Government reviews Horizon Power’s fees and charges and sets the price that our customers pay for electricity, known as ‘tariffs’. This amount is always less than the actual cost to deliver power to your business - the WA Government subsidises the difference.

Your bill is made up of two main parts:

  • A fixed charge (the cost to run power to your business)
  • A variable charge (the cost for each unit of electricity you use)

About your energy bill

Your bill includes how much energy your business is using, how that compares to the previous year and how the charges are calculated. 

  • What are my account details?

    The first few numbers you'll see in the top left of your bill is your account number. You'll need your account number handy if you ever need to contact us, or register online for My Account or our mobile app

    Your account information, including the name on your account and postal address, are located under your account number. It's important to let us know if your postal address changes - you can do this online with My Account. 

  • How much do I need to pay?

    Your account summary lists:

    • Total of previous bill: the amount of your last bill,
    • Payments & adjustments: the amount you have paid since your last bill was issued,
    • Balance: the outstanding amount on your account (if any),
    • Current charges: new charges for this bill period, 
    • Total due: the total amount owing
    • Payable by: your payment due date

    Please note:

    Your invoice number is different to your account number and is different with each bill.  

    Your supply period is approximately 60 days, so you’ll receive a bill from us about every two months.

    Your supply address is the address for which we have supplied electricity and for which this bill relates to. In many cases, this will be the same as the address above but if you have multiple accounts, this will show which property this bill relates to.

  • How do I pay my bill?

    Your payment options are listed within the payment slip, at the bottom of your bill.

    This includes direct debit, BPAY, credit/ debit card payments, mail, Centrepay or at your local post office. Learn more about these payment options and the direct debit plans available. 

    You will need your payment number to pay your bill online, orwith BPAY (in addition to your Biller Code).

  • Where can I check any products, rebates or adjustments?

    You can view any credits or charges applied to your bill and the reason why. In this example, it includes:

    • Your tariff and the cost of the electricity you have used. This is based on the number of units used in this billing period and the cost per unit. GST is added as a separate line item.

    • Supply charge: the charge to supply the electricity to your supply address. This is charged on a daily basis, whether you use electricity on that day or not.

    • Solar credit: if you have solar installed, this shows a credit for any units of electricity that have been fed back to the network. We buy each unit of electricity at a set price. If your buyback scheme has an on-peak and off-peak price, you will see two rates listed here.

    • Rebates or subsidies: if you receive any concessions, rebates or subsidies, this will appear here as a credit on your account. In this example, the customer receives the WA Government Energy Assistance Scheme.

    • Other charges: in this example, a paper bill fee has been added to the account balance. To avoid this fee, log in to My Account and switch to paperless billing.
  • How much energy did I use?

    This graph shows your household's average daily energy use so you can see how it compares to your last bill and the same period last year if you were at the same address.

    It includes the average number of kilowatt hours (kWh) you have used each day and your average electricity costs each day. This is based on your average daily use, your tariff and the number of days in this billing period. 

    You can view your energy use in more detail with our mobile app.  Our app provides your daily and hourly energy use, your current spend and an estimate of what your next bill is likely to be, based on your average daily usage.  Learn more about our app. 

  • Where is my meter read information?

    On the back if your bill is a summary of your meter information, including the date your meter was read and the number of units of used since your last bill was issued.

    The reading type will usually be ‘Normal’ and means we have taken a reading from the meter. ‘Estimated’ means we have estimated your reading using historical data for your property.

Is your bill higher than you were expecting?
