One-minute read:

Your credit history is a record of your borrowing and repayments. It can influence whether a power company will sign you up for an electricity plan. It’s good to know how credit assessments work to put you in the best possible position.

Your credit history helps power companies assess risk. Things like past payment behaviour (including payments or missed payments) and how long you've held an account show how reliably you've managed bills in the past.

If your credit history is poor, power companies may ask for extra assurance. This could include a bond, a shift to prepay, or declining the application.

Being turned down doesn’t mean you can’t stay connected. Prepay may be an option as it doesn't require a credit check. 

Support your credit rating with consistent habits. It helps to pay on time, limit new credit applications, keep an eye on your credit report, and ask for any wrong information to be corrected.

Why does my credit history matter to a power company?

When you apply for a new power plan, the power company will look into your credit or payment report. Here's what they might look out for:

  • Defaults, how long you've held an account, or patterns of late payments: These show how reliably you’ve paid bills in the past, which helps the power company assess how likely you are to pay your bills.
  • How long you've had credit accounts: A longer credit history gives the power company more information about your financial behaviour over time.

Power companies will ask that you have valid identification to confirm who you are and where you live.

What will a company say if I have a poor credit history?

If a power company raises an issue with your credit report, they may respond in one of the following ways:

  • Request a bond or security deposit before you’re accepted. If you pay a bond, it must be refunded after a year of paying all invoices on time.
  • Offer prepay (if available) rather than a standard post-pay plan.
  • Decline the application, in which case they must provide you with the reason, a reference website to compare other plans, and contact details of support agencies.

What if I’m turned down for a power plan?

If you are declined for a power plan, that power company must treat you fairly and work with you to find suitable power options. Remember:

Payment options: Missed or late payments are often associated with poor credit. If you are finding it hard to pay your power bill, it's really important to talk to your power company early. They can usually set up a payment plan to help you stay connected or put you in touch with financial mentorship to help you. If you're finding it hard to pay your power bill, learn more about your options.

Prepay plans: If you are declined due to poor credit history, prepay plans don't require credit checks. They can help you stay connected while you rebuild your credit rating. Read more here

Are there ways to support a good credit score?

While it might take time, you can strengthen your credit score with a few consistent habits:

  • Pay on time: Set reminders or automate payments for your bills. You can speak to your credit company to arrange payment plans that favour a positive credit history.
  • Keep communication open: If you’re struggling, tell your power company early. They must consider affordable payment options or refer you to a budgeting agency.
  • Limit new credit applications: Too many credit checks can reduce your score.
  • Show progress: If you’re working with a financial mentor or paying on time for several months, let your power company know – many will take your consistent efforts into account.
