Some energy providers offer tariffs so low they make you do a double-take—but finding them? That’s the tricky bit. Tariffs shift with government regulation, wholesale prices, and even the weather. But if you’re wondering which energy company has the lowest tariffs right now, here’s the short answer:

As of 2025, some of the lowest energy tariffs in Australia are offered by ReAmped Energy, GloBird Energy, and Energy Locals—depending on your state and usage profile. But the cheapest on paper isn’t always the most cost-effective once you factor in discounts, usage habits, or sneaky conditional pricing.

Let’s unpack what “lowest tariff” really means—and how to choose wisely.

What is the “lowest tariff” – and is it always the cheapest?

Here’s the kicker: low tariffs don’t guarantee a low bill.

Many retailers advertise attractively low per-kWh rates (the tariff), but then quietly sting you with high daily supply charges, conditional discounts, or usage penalties if you don’t pay on time.

Tariff structures generally include:

• Usage charge (per kWh): what you pay for actual electricity used

• Supply charge (per day): a flat daily fee just for being connected

• Time-of-use or demand charges (if applicable): pricing varies depending on when or how you use energy

So, a company with the lowest per-kWh usage rate might not have the lowest total bill once you include supply charges.

Which energy retailers offer the lowest usage rates in 2025?

According to recent energy price comparison data from state regulators and consumer platforms like Energy Made Easy and Victorian Energy Compare, these providers consistently show up with competitive tariffs:

Your actual cheapest option depends heavily on your postcode, usage pattern, and whether you’re on a smart meter or not.

How does location affect your energy tariff?

Energy isn’t priced equally across the country—and that’s by design. Australia’s energy market is state-based, and each area has different distributors, infrastructure costs, and regulatory frameworks.

• NSW & QLD: GloBird and ReAmped often lead on price, especially for households with medium to high usage.

• VIC: Tango Energy and Momentum are frequently top picks for value, especially on single-rate tariffs.

• SA: Energy Locals and OVO Energy perform well on simplicity and green credentials.

• WA & NT: These are government-regulated markets, so your options are limited, and switching providers isn’t possible in most cases.

This means what’s cheapest in Melbourne might be mid-tier in Brisbane.

Is switching worth it for a lower tariff?

Here’s where behavioural science chimes in. Most Aussies stay with the same energy retailer for years—even when they know they could save. Why?

It’s a classic case of status quo bias and loss aversion. We fear the unknown more than we value potential gains.

But switching is simpler than ever, and most platforms handle the admin for you. If you haven’t compared plans in the last 12 months, chances are you’re overpaying by $300–$600 a year, according to the ACCC.

What should I check before switching?

Not all low-tariff plans are equal. Before jumping ship:

• Read the energy fact sheet: every plan must have one, showing all rates and fees

• Check if discounts are conditional: some only apply if you pay by direct debit

• Look for exit fees: rare these days, but still worth checking

• Compare actual estimated bills, not just per-kWh rates

Sites like Energy Made Easy (for all except VIC) and Victorian Energy Compare let you plug in your last bill and see how plans stack up based on your real usage.

Is a broker or comparison site better?

You’ve got three choices:

1. Do it yourself via state government tools

2. Use a commercial comparison site like iSelect or Canstar

3. Work with an energy broker

Option three is rising in popularity—especially for small businesses and landlords. A good energy broker can not only find low tariffs but also optimise for things like peak demand charges, solar feed-in, and contract terms.

One example of how brokers are transforming the game is covered here, especially with the shifting landscape in 2025 and beyond.

Are renewable or green energy plans more expensive?

Surprisingly, not always.

Thanks to more competition and falling wholesale solar costs, many green energy plans are now price-competitive with standard ones. Some retailers—like Energy Locals and OVO—bundle 100% carbon offsetting at no extra charge.

If you’re choosing based on values and cost, don’t assume you have to pay more for a green conscience.

FAQ

What’s the difference between a retailer and a distributor?
A retailer sells you the energy and sends your bill. A distributor owns the poles, wires, and meters. You can choose your retailer—but not your distributor.

How often do tariffs change?
Retailers can update prices at any time, but many follow the financial year or regulatory resets. Watch out for changes around July each year.

Can solar panels lower my energy tariff?
Not directly—but they can slash your usage charges, and some plans offer generous solar feed-in rates that offset your costs.

Final thoughts

Finding the “lowest tariff” energy company in Australia isn’t just about scanning a price list—it’s about matching the right plan to your usage habits, location, and values. And while chasing the absolute cheapest rate might save a few bucks short-term, sometimes the best value comes from stability, customer support, or green incentives.

For businesses or savvy households wanting to take the guesswork out, working with an energy broker could be a smart move—especially in 2025’s dynamic market.

Because at the end of the day, the cheapest bill is the one you don’t have to stress about.
