We're making changes to our bills

November 02 2022

These changes are to align with Horizon Power’s updated brand and includes our letterheads, envelopes, and bills. These updates have been made to make the key areas of the bill easier to read.

See what's changed

Your chosen payment method, bill delivery method, rates and charges will remain the same. It’s just the look of the bill that has changed. 

We are letting you know about the change to reassure you the new bill is from Horizon Power. The new designs will commence in January 2023 and make take up to two months for your new look bill to arrive.

Know where to find key information about your energy costs

Your 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, is located under your account number.

Your account summary

UpdatedBill - Account summary.png

Your account summary lists: 

  • Total of the 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 billing period 
  • Total due: the total amount owing 
  • Payable by: your payment due date. 

On the back of your bill you can view: 

  • 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 much energy did you 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 Horizon Power 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.

  • How do I know the new bill is from Horizon Power?

    We are reaching out to customers through emails, bill messaging and the Horizon Power website to assure the bill design changes are from us. 

  • Why was the bill design changed?

    You may have noticed a new look and feel to Horizon Power. In 2020 Horizon Power completed a light refresh to our brand. We are now working to update key customer communications to align them with our updated brand. Additionally, changes have been made to make the invoice easier to read, by highlighting the main invoice features, such as the account summary and consumption comparison. 

  • Will the design changes affect the way I pay my invoice?

    No. Your chosen payment method, bill delivery method, rates and charges will remain the same. It’s just the look of the bill that has changed. We’ll be rolling out the new bill design in the coming months, so expect to see it in your letterbox or inbox early 2023. 

  • Have my charges changed?

    While your new bill may look different, your charges haven’t changed. 

  • Can I call someone to check that my invoice is from Horizon Power?

    Absolutely. If you have any questions, please contact your local office or call our Customer Call Centre on 1800 267 926. 

  • What inspired the design?

    The texture used on the bill background is based on inspirations from landscapes from regions across Western Australia. These landscape patterns include the Bungle Bungles, Karijini, Gascoyne Junction and Lucky Bay.  

    The landscape texture used on the updated bill design is based on the Bungle Bungles.
