Methodology & Important Notes

Most Satisfied Customers | Origin Energy

Origin Energy has taken over the top spot in Canstar Blue’s SA gas supplier ratings. The retailer scored five stars for overall satisfaction, value for money, ease of sign-up, bill and cost clarity, customer service and online tools and advice.

How we rate SA natural gas providers

We’ve surveyed 310 bill-paying customers across Adelaide and the surrounding areas to find out what they think about their gas supplier in respect to the customer service, bill and cost clarity and value for money. Keep in mind, while this report looks at two of the most prominent retailers in South Australia, there may be others operating in your area.

Canstar Blue surveyed 310 South Australian households for their feedback on their natural gas retailer. Respondents had to live in SA, have a gas account and pay the bills for their response to be eligible.

The outcomes reported in these ratings are measured via PureProfile’s accredited online research panel.

Respondents rate their satisfaction with their natural gas provider from zero to 10, where zero is extremely dissatisfied and 10 is extremely satisfied. Provider satisfaction was rated by respondents on the following criteria:

Overall satisfaction: with the natural gas supplier.
Value for money
Customer service: email, telephone service.
Bill and cost clarity: do you understand your bill?
Online tools and advice: apps to monitor usage, account management.
Ease of sign-up.

The winning brand is the one that receives the highest overall satisfaction rating once all the scores from the overall satisfaction criteria are combined and averaged.

Overall satisfaction is asked as a specific question and represents an individual measure, not a combined total of all criteria.
When we cannot determine a clear winner from the criteria for the overall satisfaction rating, we will then look at the other criteria measured in the rating.
- The brand with the highest number of five-star ratings within the supporting criteria will become the five-star recipient in overall satisfaction, and thus win the award. If a clear leader still cannot be determined from the supporting criteria, joint winners will be declared.

Brands must have received at least 30 responses to be included, so not all brands available in the market have been compared in this survey. The brands rated in this survey are listed below in order of best overall satisfaction.

Fees payable by product providers for referrals and sponsorship or promotion may vary between providers, website position, and revenue model. Sponsorship/promotion fees may be higher than referral fees. If a product is sponsored or promoted, it is an ad and it is clearly marked as such. An ad might appear in different places on our website, such as in comparison tables and articles. Ads may be displayed in a fixed position in a table, regardless of the product’s rating, price or other attributes. The location of an ad doesn’t indicate any ranking or rating by Canstar Blue. Payment of fees for ads does not influence Value Rank or Customer Satisfaction Ratings. See How We Get Paid to find out more.

The data in the table is updated within 24 hours of Canstar Blue becoming aware of a change. You can find a description of the initial sort order below the table. You can use the sort buttons at the top of each column to re-order the display. Learn more about our Gas Value Rank Methodology.

Please note that the Satisfaction Rating displayed in the table is a rating relating to customers’ overall satisfaction with the brand. It should not be confused with an individual product rating. Learn more about Brand Satisfaction ratings and for more information on how the Brand Satisfaction ratings are calculated, read the Canstar Blue Most Satisfied Customers Methodology.

The results do not include all energy retailers or products in the market and may not compare all features relevant to you. Canstar Blue does not supply electricity or gas services. If you decide to apply for a particular energy product, you will deal directly with the retailer, not with Canstar Blue. Fees, charges, product information and contract terms should be confirmed directly with the relevant retailer.

Some plans may require you to meet certain conditions before a discount may become available to you. Check the energy provider’s plan information for details of all possible discounts that may apply and any conditions that need to be met for you to be eligible for these discounts.

Check your current plan’s exit fees and other termination provisions before changing providers.

Some plans may have a minimum term that is longer than one year. In that case the total cost over the term will be much higher than the estimated Price, which is for one year only. Consider the provider’s detailed product and pricing information before making a decision to take out a new plan or switch electricity providers.

Pricing Information

The price shown is inclusive of GST and is the estimated lowest possible price a representative customer would be charged in a year for each plan, assuming all conditions of discounts offered, if any, have been met. Gas usage assumptions have been derived from the average usages advertised by a selection of retailers in the distribution region as shown at the top of the table.

The general usage assumptions for products displayed in the table have been derived from:

the average usages advertised by a selection of retailers in the distribution region as shown at the top of the table. The figures provided are intended to serve as general estimates and should be used for information only. If the amount of gas you actually use differs greatly from this estimate, your bill could be significantly larger or smaller than the estimated price/year listed for each plan; or
if you have provided usage data from your gas bill, the estimated annual amount payable for this plan is based on your individual circumstances.

The estimated yearly Price is based on single rate tariffs, which is when a flat usage rate is charged for ‘blocks’ of gas consumed and could be a limited amount per day, month, quarter, which may include a second block with a different usage rate applied, or, season.

Some plans may have a minimum term longer than one year – in that case the total cost over the term will be much higher than the estimated yearly Price (which is only for one year).

Some plans may apply additional charges to the price shown. Always check the energy provider’s plan information for details of all charges that may apply.

How to get a better deal on gas in SA

Customers connected to the gas distribution network can access one of two types of contracts with their gas supplier – standard contracts and market contracts. Understanding the difference is the first step to saving money.

Standard contracts have prices set by the retailers, but they have various conditions still set out in law, including the fact that they have no contract period or exit fees.
Market contracts are set almost entirely by the retailers. They have varying contract lengths and conditions, but often provide the opportunity to save through discounts.

Market contracts will almost always work out cheaper than standard contracts, provided you meet the conditions of any discounts. Market contracts can come with either variable or fixed rates. If you haven’t switched plans in recent years, you will likely save money by switching to a new offer with a discount or other sign-up incentive. Ultimately though, you will need to get to know usage and supply charges and compare rates between different suppliers. If you think you’re paying too much for gas, you probably are. It’s the same deal when it comes to electricity, so make sure you shop around.

FAQs about SA natural gas providers

Keep in mind there are several gas companies operating in South Australia. While the four in our review can generally be considered the most prominent, retailers including Alinta Energy, Lumo Energy and Red Energy also sell natural gas across SA. However, the vast majority of households remain connected with one of the big three. Here is a list of gas suppliers currently offering plans in South Australia according to our database:

Keep in mind, other retailers may be added to this list in the future.

In South Australia, the gas distributor is Australian Gas Networks (formerly Envestra). This is who you will need to contact in the event of a gas leak or other emergencies. If you’re worried about signing up with a small gas supplier, remember these companies are simply the customer-facing part of your overall service. They handle your billing and general enquiries, but it’s the gas distributors that are actually responsible for your supply.

Households who can’t access the natural gas distribution network can purchase liquefied petroleum gas (LPG) instead.

Natural gas is charged per megajoule (MJ) – the unit of measurement for gas. The exact price you’ll pay for gas in SA depends on a number of factors, including your gas retailer, plan and tariff. In SA, gas retailers charge for gas in ‘blocks’ of daily usage. For example, you might pay 4.2c per MJ for the first block of 30MJ, followed by 2.2 cents per MJ for all remaining usage. It’s important to check your energy plan information document for all rates. Some suppliers charge for gas in two daily blocks, while others charge in multiple increments.

In addition to these gas usage charges, also pay close attention to the daily supply charges in your price fact sheet. These are the costs you’ll need to pay simply for the pleasure of being connected to the gas network. These can add a significant amount to your overall bill – up to $1 a day in some cases. It’s entirely possible that gas supply charges could contribute a higher proportion of your overall costs than gas usage charges, especially if you don’t use gas for hot water heating. So, be sure to check all the rates listed before making a decision.

There are lots of things to think about when it comes to picking a gas supplier for your home. We asked respondents to our survey in 2024 about their main reasons for picking their gas supplier. This is what we found:

29% wanted the same brand for both electricity and gas supply.
22% shopped around and compared plans and prices.
16% were attracted by a big discount.
22% went with a retailer name they recognised.
8% were attracted by a different sign-up incentive (e.g. movie tickets).

32% of gas customers in SA signed up to their supplier over the phone and 36% did so online. This year, we found that 53% of South Australians think they get a good deal on gas.
