Methodology & Important Notes

Most Satisfied Customers | Red Energy

Red Energy is our highest-rated natural gas supplier for 2023, after scoring a perfect five-star result in all six of our research categories. Red Energy beat out ‘big three’ providers Origin, AGL and EnergyAustralia to claim the top spot.

How we rate NSW natural gas suppliers

We’ve surveyed more than 1,000 bill-paying customers across New South Wales to find out what they think about their gas suppliers. Price is hugely important, but the best deal for you could also mean great customer service, helpful tools and advice, or having a retailer with a strong focus on environmental sustainability. So, which supplier is really cooking with gas in NSW? Please keep in mind, while this report looks at six of the most prominent retailers in NSW there may be others operating in your area.

Canstar Blue surveyed 1,074 NSW households for their feedback on their natural gas retailer. Respondents had to live in NSW, have a gas account and pay the bills for their response to be eligible.

The outcomes reported in these ratings are measured via ISO 26362 accredited research panels managed by Qualtrics.

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: measured consumer satisfaction with a natural gas provider as an individual score NOT a combined total of all criteria.
Value for money: cost was low for the quality and effectiveness of the natural gas provider.
Customer service: the natural gas provider had multiple service points for customers, e.g. telephone, email, online chat.
Bill and cost clarity: the natural gas provider had an easy-to-understand bill.
Online tools and advice: the natural gas provider had an app or online account to monitor energy usage, pay bills and manage account information.
Ease of sign-up: the natural gas provider had a simple sign-up process.

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.

Canstar Blue may earn a fee from its Online Partners for referrals from its website tables, and from sponsorship or promotion of certain products. 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.

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 NSW

While energy plans may seem confusing, this report has identified a few key things you can do to get a better deal on natural gas. It might seem like hard work, but when it comes to gas and electricity, you only find the best deals with a little leg work. Here are the three most important things to consider:

What type of contract are you on? Standard contracts are almost always more expensive than market offers, so switching from the former to the latter is the first positive step towards securing cheaper rates.
Compare the usage and supply charges of various gas plans. Energy companies are required to publish their plan information documents on their websites, which is where you will find these details.
Consider the discounts and other incentives offered. Once you’ve worked out what cheap and expensive usage and supply prices look like, consider the discounts being offered and how they compare to other deals. Make sure you understand the conditions of the discount and how long the benefit period is.

Also consider how other consumers rate their energy suppliers. You will never really know how good or bad a retailer is until you’re a customer, so online reviews like ours provide an insight into what you can really expect. It’s the providers that strike the perfect balance between price and good customer service that usually rise to the top of our ratings. This year, Red Energy is the gas supplier to beat in NSW, but be sure to compare a wide range of options before diving in.

FAQs about NSW natural gas providers

The NSW gas market continues to become more competitive, after price restrictions were lifted in 2017. If our customer ratings are any indicator, it will be worth keeping your eyes peeled for future offers as other retailers attempt to chip away at the dominance of the big three. Here is a list of gas suppliers currently offering plans in NSW:

As always, it’s worth comparing a wide range of plans available in your area before making a decision.

Besides contract types, usage rates, supply charges, tariffs and discounts, the other crucial thing that will impact the amount you pay for gas is where you live. There are three different gas networks in NSW and gas prices can vary significantly between them. For example, an Origin customer on one network might have higher usage charges than another Origin customer with the same plan, living on a different distribution network. This is because energy distributors have their own costs and these are passed on to customers through retailer charges. The three distribution networks in NSW are:

Jemena Gas Networks NSW: servicing Sydney, Newcastle, Central Coast, Wollongong and parts of country NSW
Central Ranges System: servicing Tamworth
Wagga Wagga Gas Distribution Network

ActewAGL – the primary electricity and gas retailer in the ACT – also serves some customers in regional NSW.

Usage charges will likely make up the majority of your overall energy costs, but it’s also important to pay attention to supply charges, because the providers with lower usage rates often make up for these with higher daily supply charges. These are the costs you incur on an ongoing basis simply for being connected to the network. The cheapest gas usage charges that you’re likely to find in NSW will be around three cents a megajoule – the unit of measurement for gas. To put this into context, a typical gas oven will use around 12 megajoules (MJ) an hour. Fixed daily supply charges usually cost around 40-70 cents.

Fortunately, gas tariffs in NSW are fairly simple. Households are charged for gas in ‘blocks’, with the first block of gas used (say, 20MJ) usually costing the most. For example, you might pay 4.2 cents for the first block of 20 megajoules a day, then 2.5 cents for the next block, and so on.

There are lots of things to think about when it comes to picking a gas supplier for your home. In 2023, we asked respondents to our survey in NSW a range of questions to get a better idea of where customers stand with their natural gas provider. This is what we found:

37% wanted the same gas supplier as their electricity retailer
21% went with a brand they recognised
21% shopped around and compared gas plans on price
15% were attracted to a big discount

One quarter (25%) of NSW gas customers signed up to their supplier over the phone and 40% signed up online. Just 39% of NSW survey respondents think they get a good deal on gas, although only 11% have switched gas suppliers in the last two years.
