Sumo Energy review: Our verdict

Sumo's prices are on the low end across all states, ranging from 13% - 22% less than the reference price. Prices are highest in Victoria and lowest in New South Wales.

Here are some of the benefits of signing up with Sumo Energy:

  • Bundling your gas and power on some plans can give a 1% discount on your rates.
  • Melbourne-based customer support means you'll get help from locals.

What's the catch?

  • Bundling discounts for Internet plans brings them in line with others on the market, instead of making them especially cheap.
  • Sumo was hit with a $1.2 million fine in July 2021 for hiking energy prices soon after luring in customers with the promise of low rates.

If you're ever unhappy with your energy plan, you can switch to another provider as Sumo doesn't have any lock-in contracts.

Can I bundle gas and electricity with Sumo Energy?

Yes. Bundling a gas or electricity plan with Sumo Internet will give a bigger discount on your NBN bill.

If you're not after an Internet plan as well, bundling gas and electricity may provide some extra convenience, but no discount.

Sumo Energy and Internet bundling

Sumo sells its NBN plans at a discount if you have an active gas or electricity account with it: $5 less with gas, $10 less with power, or $15 less with both.

You have to sign up to a 12- or 24-month contract to receive this discount, with a maximum early termination fee of $250.

Solar Energy

Does Sumo Energy offer solar plans?

Sumo Energy will provide a feed-in tariff for excess solar power that you export to the grid. If you don't already have a solar energy system, unfortunately Sumo won't help you with installing one.

How good is the feed-in tariff?

Sumo Energy's feed-in tariffs are fairly average, with particularly decent rates in Victoria. New South Wales residents won't get quite as much.

Here's a breakdown of solar feed-in tariffs by state.

Benchmark range. The Independent Pricing and Regulatory Tribunal's report has set NSW's benchmark range for 2020-2021 to 6-7.3c/kWh for feeding electricity into the grid.

Sumo's range.
Expect 5c/kWh or 14c/kWh, depending on which plan you opt for.
If you purchase a solar system.
You can get 5.5 c/kWh back.

Benchmark range. The Essential Services Commission for Victoria has put the state's benchmark at 6.7c/kWh.

electricity icon
Sumo's range.
Expect 6.7c/kWh or 10c/kWh, depending on which plan you opt for.
If you purchase a solar system.
You can get 10.2 c/kWh back.
We've used data from South East Queensland to give you the information below.

Benchmark range. There is no set minimum solar feed-in tariff for South East Queensland, but the rates are monitored by the Queensland Competition Authority.

Sumo Energy customer service

Data from the 2019-2020 market report by the Australian Energy Regulator is a valuable source for determining how good a provider's customer service is. This is how Sumo Energy performed during that period compared to others:

  • Understand your current electricity, gas or solar plan
  • Switch to a new plan
  • Figure out your energy bill
  • When you're experiencing any financial difficulty

Get a cost estimate

Important notes: The estimated price we show by default is based on a single rate tariff. On your bill this might be known as a "peak tariff", "peak only" or an "anytime tariff". There are other tariff types available to customers and you may need to contact your provider if you are on these tariffs:

  • Single rate with a controlled load
  • Time of use
  • Time of use with a controlled load

The price estimate should not be used as an official quote, but an indication of what your costs may be on the plan. It varies based on whether you provide us with your bill details. You can learn more here.

    Is the 27% discount for prompt payment applied to the bill total [including GST] or just the usage content?
