Frequently Asked Questions

How do I switch power companies?

Switching is easy! Once you choose a new provider, they'll handle the entire process. Simply provide your details and meter number, and they'll coordinate with your current provider. The switch typically takes 5-10 working days with no interruption to your power supply.

Will my power be interrupted when I switch?

No, your electricity supply won't be interrupted during the switch. The transition happens seamlessly behind the scenes, and your power will continue to flow as normal.

What information do I need to switch?

You'll need your current address, meter number (ICP number), and basic contact details. If you're unsure of your ICP number, it's usually on your power bill, or we can help you find it.

Are there any fees to switch providers?

Generally, there are no fees to switch providers unless you're breaking a fixed-term contract with your current provider. Many companies also offer sign-up credits to new customers.

How often should I compare power companies?

We recommend comparing power companies at least once a year. Prices and promotions change regularly, and you might find a better deal that could save you hundreds of dollars annually.

What's the difference between fixed and variable rates?

Fixed rates stay the same for a set period (usually 12-24 months), providing price certainty. Variable rates can change with market conditions but offer more flexibility as they typically don't require a fixed-term contract.
