Origin Energy vs AGL: Which Is Cheaper for NSW Households in 2026?

SaveNest Editorial Team · 2026-11-03 · 9 min read

If you live in New South Wales, there is a good chance your power bill comes from either Origin Energy or AGL. Both are among the biggest retailers in the state, so "Origin Energy vs AGL: which is cheaper for NSW households in 2026?" is one of the most common questions we hear. The honest answer is that neither retailer is cheaper for everyone. The winner depends on your distribution network, your tariff type, how much power you use, when you use it, whether you have solar, and which discounts apply to you.

This guide explains how each retailer's pricing works in NSW and where the real differences show up. It also shows how to run a like-for-like comparison with your own numbers. We don't quote exact rates here because they change often and vary by postcode.

The short answer: it depends on your postcode, tariff and usage

Origin and AGL are both large "gentailers", meaning they own generation as well as sell retail electricity. Both sell a range of plans in every part of NSW. Each has a standing offer (the default plan you land on if you never choose one) and a range of market offers, which are usually cheaper but come with conditions.

On any given day, one retailer's best plan for your suburb may beat the other's, and the next quarter it may flip. Smaller retailers sometimes undercut both, so a fair comparison should include them. Your goal is not to find the "cheapest retailer" in general. It is to find the cheapest plan for your household.

Origin Energy vs AGL in NSW: which is cheaper in 2026?

Here is how the comparison breaks down in practice. Both retailers price NSW plans using the same building blocks, so the differences come from how each one sets and discounts them.

Daily supply charge: a fixed amount you pay every day, whether or not you use any power. It varies by distribution network and retailer.
Usage rates: cents per kilowatt-hour (kWh). On a single-rate plan it is one price all day. On a time-of-use plan it is split into peak, shoulder and off-peak rates.
Controlled load: a separate, usually cheaper rate for dedicated circuits such as electric hot water, where your meter and network support it.
Discounts and credits: pay-on-time discounts, direct debit discounts, sign-up credits or bill credits. These can be significant, but they are not all equal (see below).
Solar feed-in tariff: the rate you are paid for exporting surplus solar to the grid.

Because Origin and AGL both use this structure, you can't tell which is cheaper by looking at the headline discount. A plan advertising a large discount off a high rate can cost more than a plan with a smaller discount off a lower rate. Only the total annual cost, based on your own usage, settles it.

Know your NSW network and tariff first

NSW has three main electricity distributors, and which one serves you affects your prices. Ausgrid covers Sydney, the Central Coast and the Hunter. Endeavour Energy covers Western Sydney, the Illawarra and the Southern Highlands. Essential Energy covers most regional and rural NSW. Network charges differ between them, so the same retailer plan can have different rates in different postcodes.

Your bill will also show your tariff type. Many households are on a single-rate tariff, but time-of-use tariffs are common, especially with a smart meter. If you have electric hot water on a separate controlled load, or you charge an EV overnight, the time-of-use and controlled load rates may matter more than the headline rate. For a deeper look at how NSW pricing works, see our NSW electricity guide.

How to compare plans properly

Compare total cost, not just the usage rate

A lower usage rate with a higher daily supply charge tends to suit larger households that use a lot of power. A higher usage rate with a lower daily supply charge can suit a small household, an apartment, or a home that is empty much of the time. The calculation is simple:

Annual supply cost = daily supply charge x 365 days
Annual usage cost = your yearly kWh x the relevant usage rates
Subtract discounts you will realistically receive
Add any recurring fees, and subtract credits you are actually eligible for

Use your last four quarters of bills, or your smart meter data, to get an accurate yearly kWh figure. Checking one summer bill gives you a skewed picture.

Guaranteed discounts vs conditional discounts

Retailers describe discounts in different ways. A guaranteed discount applies as long as you stay on the plan. A conditional discount, such as a pay-on-time or direct debit discount, only applies if you meet the condition every time. If you sometimes pay late, a conditional discount that looks generous on paper can disappear. Check the Price Fact Sheet to see which is which, and check whether the discount applies to the whole bill or only to usage charges.

Solar feed-in tariffs

If you have rooftop solar, the feed-in tariff matters as much as the usage rate. Feed-in rates vary by retailer and plan, and a plan with cheap usage but a very low feed-in tariff can cost solar owners more. NSW's pricing regulator, IPART, publishes a benchmark range for solar feed-in tariffs each year. Use it as a reference point to judge whether an offer is reasonable. If you have or are planning solar, a free solar savings estimate can show how your export rate changes the numbers.

Where Origin and AGL differ in practice

Rather than assume one is always cheaper, look at the features that tend to differ between plans.

Bundling: both retailers offer gas alongside electricity, and some plans reward you for holding both. A bundle discount only helps if the gas rates are also competitive, so price each fuel separately before accepting a bundle. You can check current options on our gas deals page.
Battery and virtual power plant programs: both retailers run offers aimed at households with home batteries. Terms, credits and lock-in periods vary, so read the conditions carefully before signing up. The federal government's Cheaper Home Batteries program has also changed the economics of home batteries since mid-2025, so check what applies when you buy.
Green options: both offer GreenPower or carbon-neutral add-ons at extra cost. They are optional, so make sure they are not quietly included in the plan you are comparing.
App and billing tools: usage tracking, billing alerts and payment flexibility differ. They won't change your rate, but they can help you avoid bill shock.

Check the fine print before you switch

Benefit periods: some offers include a discount for a set period. When it ends, your rates can rise. Retailers must notify you about price changes, but you still need to read the notice.
Exit fees: many market offers have no exit fee, but some do. Check the fact sheet.
Cooling-off: you generally have a short cooling-off period after signing up, which gives you time to change your mind.
Rebates: NSW Government energy rebates are applied through your retailer. Check that your rebate carries across if you switch.
Disputes: if something goes wrong, the Energy and Water Ombudsman NSW (EWON) is a free dispute resolution service that can help.

Is it worth switching in 2026?

It often is, especially if you are on a standing offer, your discount period has ended, or you haven't compared plans in more than a year. The Australian Energy Regulator's Default Market Offer (DMO) sets a ceiling on standing offer prices in NSW each financial year, and it resets on 1 July. It is a cap, not a recommendation. Many competitive market offers sit below it, but you only get them by actively choosing a plan.

Your bill must also show a "Best Offer" message from your current retailer. That is useful as a first check, but it only shows that retailer's own plans, not the whole market. For a broader view, use the government's Energy Made Easy comparison site or our electricity deals page.

Policy is also shifting. The federal Solar Sharer policy aims to give households in NSW, south-east Queensland and South Australia free or very cheap power for a few midday hours. It is being phased in through the default offer framework, so check how each retailer has actually implemented it on the plan you are considering. If you can shift your dishwasher, laundry or EV charging to midday, plans like this could change which retailer is cheapest for you.

Which retailer might suit which household?

Households with solar: focus on the feed-in tariff and any midday offers, not just the usage rate.
Households with electric hot water or an EV: compare time-of-use and controlled load rates closely.
Small households and apartments: a lower daily supply charge usually matters more than a low usage rate.
Large families and heavy users: a low usage rate generally beats a low supply charge.
Renters: look for no-exit-fee plans so you can move without a penalty.

Steps to Take

Find your latest bill and your yearly usage. Note your distributor (Ausgrid, Endeavour or Essential), your tariff type and your total kWh over the last 12 months.
Get the Price Fact Sheet for any plan you are considering. Check the supply charge, usage rates, feed-in tariff, discount conditions, benefit period and exit fees for both Origin and AGL.
Work out the real annual cost for each plan using your own usage and only the discounts you will reliably receive.
Widen the search beyond these two retailers. Compare other retailers on our electricity deals page or Energy Made Easy, because a smaller retailer might beat both.
Switch, then diarise the end of any discount period. Set a reminder to re-check your plan about 11 months later so you don't drift onto higher rates.
Review your gas and other bills at the same time. If you have a gas connection, a quick look at gas deals can find savings in the same session.
