How do I compare electricity providers?

To compare electricity providers effectively: 1) Check unit rates (¢/kWh), 2) Review daily fixed charges, 3) Consider contract terms and exit fees, 4) Look at sign-up bonuses and promotions, 5) Read customer service ratings, 6) Factor in additional features like mobile apps or rewards programs. Use our comparison tool above for personalized results.

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.

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. Set a calendar reminder to check rates each winter when usage is highest.

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. Fixed rates are currently 24-26¢/kWh while variable rates range from 22.8-28¢/kWh.
