Sumo Power All You Can Eat plan

This plan is designed to help customers avoid bill shock by having them prepay their annual electricity bill in one or two instalments. Using your electricity usage history, Sumo Power estimates your electricity usage for the year ahead and charges customers accordingly. It’s called ‘All You Can Eat’ because even if your usage exceeds what Sumo Power expected, you won’t be charged anything extra. Any changes to your electricity usage habits will simply be accounted for when prices are adjusted in the following 12 month period.


Sumo Power has three simple ways for customers to pay their bill:

  • Online: Accepts Visa, Mastercard and Amex. 0.7% card surcharge applies.
  • BPay: Pay with your mobile using the biller pay code.
  • Telephone: Use your phone to call Sumo and pay the old fashioned way.

Sumo Power is also working on a ‘My Account’ feature for its website which will let customers view their bills and electricity usage figures online.

Is Sumo Power right for me?

Sumo Power may be new, but it holds its own in the electricity retail market and has brought some interesting new deals to the table. Its rates are reasonable and its discounts are pretty generous, particularly during the bonus period. There are also no exit fees on its regular market offers, meaning you’re free to leave if you’re not happy.

In addition, Sumo Power is one of only two retailers in Australia to offer a fixed cost plan. If you’re comfortable fronting your annual electricity bill in one or two payments, then this plan is a great way to give you peace of mind. That said, you need to make sure you’re using enough electricity to get your money’s worth.

Finally, while Sumo Power’s discounts are impressive, you should always check the base rates when comparing retailers. Sometimes large discounts are masking increased rates, so it’s important to look closely at the fine print when comparing power companies.
