WA gas suppliers battle over big discounts

The Western Australia gas market is almost unrecognisable from just a few years ago, with new retailers now competing for your business and genuine price competition helping you save. While the WA gas market has been fully contestable since 2004, Alinta Energy remained the state’s only residential and small business gas provider for many years. In March 2013, however, Kleenheat launched its WA gas service, stepping up as the first serious challenger to Alinta Energy in Perth and other areas along the west coast. Since then, AGL, Origin and Simply Energy have also moved west to compete for customers, resulting in a state of intense price competition, fought largely over big discounts – meaning it’s time to take advantage.

So, where can you find the best deal on price, but also customer service? Each year, Canstar Blue surveys hundreds of gas customers across WA to find out which suppliers are living up to expectations. With so much competition and bonus incentives now on offer, there’s no reason why you should settle for anything less than five-star value and service. This year’s review has compared AGL, Kleenheat and Alinta Energy on customer satisfaction. Origin and Simply Energy did not achieve the minimum sample size required to be included in the ratings.

Here are the best gas providers in Western Australia, as rated by consumers in Canstar Blue’s latest review:

  1. AGL
  2. Kleenheat
  3. Alinta Energy

AGL has been crowned the best-rated natural gas supplier in Western Australia, beating Kleenheat which held the title the past five years. AGL recorded five-star reviews across most categories, such as bill & cost clarity, online tools & advice and value for money, in addition to overall satisfaction. Kleenheat received four stars overall but performed very well in certain areas, while Alinta Energy finished bottom of the pile with three stars overall.

Kleenheat

Kleenheat Logo

Kleenheat is part of the Wesfarmers group, which also includes retail brands Target, Kmart, Bunnings and Officeworks. This connection can pay off, with Kleenheat offering further savings for RAC members as well as additional flybuys points that can be earned for every dollar spent on gas bills. A $50 welcome bonus is also up for grabs for new customers who switch their natural gas to the Monthly Smart Saver plan or Standard Form Contract. In addition to those promotions, all three Kleenheat gas plans include generous discounts, as follows:

  • Standard Form Contract: This plan brings a 12.5% discount off gas usage charges for paying on time. It has quarterly billing with paper or email bills.
  • Monthly Smart Saver: This plan bumps up the discount to 25% off gas usage charges, guaranteed for at least two years. Customers must pay by direct debit. The plan has monthly email billing. Charges may apply for paper bills.
  • Monthly Energiser: This plan has the biggest discount at 35% off gas usage charges. The 35% off applies for 24 months, and customers must pay by direct debit. The plan has monthly email billing. Charges may apply to paper bills.

However, the biggest discount of all is available to RAC members who could be eligible for an extra 3% discount, taking the maximum to 38% off gas usage charges for the first 24 months. Kleenheat says the bonus discount is for supporting local WA businesses.

Alinta Energy

Alinta Energy Logo

A major gas and electricity retailer across Victoria, NSW, QLD and South Australia, Alinta Energy maintains a strong presence in Perth as it attempts to fight off the challenge of the newer retailers to set up shop in the west. Acquired by Chow Tai Fook Enterprises – a Hong Kong based conglomerate – in 2017, Alinta certainly seems to have reacted to the increased competition in WA, offering generous discounts off gas usage charges and no lock-in contracts across all products. It also has a rewards program that brings money off various entertainment activities. These are Alinta Energy’s WA gas plans and their respective discounts currently available:

  • Fair Go 35: Offering a 35% discount off usage charges, the Fair Go 35 comes with a 12-month benefit period. Expect quarterly billing with the choice of how you want to receive your bills, as well as flexible payment options.
  • Fair Go 25: A smaller discount of 25% off usage charges is on offer, but instead this deal comes with a three-year benefit period.
  • Sports Pack Gas Plan: This product scraps the discount, instead offering customers a 12-month Kayo Basic subscription, ideal for sport fans.

Alinta Energy Rewards brings big savings off local attractions in WA, with customers able to log-in and apply for tickets via the retailer’s online rewards shop.

Utility giant Origin arrived in Western Australia to much media attention in 2017. It gives households in the state three different gas products to choose from based on personal preferences. Two of its plans come with variable rates, while the other locks in rates for 12 months. And like most other providers, Origin’s gas plans come with no lock-in contracts or exit fees.

  • Origin Supply: This is Origin’s most basic gas plan with no discounts, meaning it works out more expensive than the products below.

WA gas customers with Origin can manage their account and bills online at any time of the day.

Perth Energy

Perth Energy Logo

Perth Energy has been supplying natural gas to businesses across WA for more than 15 years, but now offers a standard residential plan for households in the Perth area. It can also supply areas outside of the Perth metropolitan area. This includes Geraldton, Bunbury, Capel, Busselton, Albany and the Kalgoorlie-Boulder area. Perth Energy also sells electricity and solar solutions to business customers.

Regulated Gas Prices

While WA now has plenty of gas competition, there is very little difference in the actual gas rates that households pay. This is because Western Australia has a regulated price cap, meaning the retailers have a limit as to what they can charge. As you might expect, in most cases the retailers charge as much as they are allowed, or at least very close to the regulated price. This means that discounts really can make the difference when it comes to the overall price you could pay. As mentioned above, discounts of up to 56% off gas usage charges are now on offer. The extra incentives offered by the retailers can also help you decide which plan delivers the best overall value for your money.

Cheapest Gas Prices in WA

With gas prices regulated in WA, discounts really can make the difference to overall costs, provided, of course, that you meet the conditions of those discounts. To help you decide which provider and plan will be best for you, the following table lists the cheapest product from each of the five WA gas suppliers on our database. These price estimates are based on yearly gas usage of 27,620 units, so keep in mind that costs will vary depending on your personal circumstances. Annual costs assume discount conditions are met.

Gas Provider^ Gas Plan Discount Annual Cost*
AGL Set and Forget 56% for paying by direct debit $1,787incl. conditional discount
Simply Energy Simply Footy Saver 50% for paying on time $2,027incl. conditional discount
Origin Energy Everyday Rewards 0% $2,581
Kleenheat Monthly Energiser 35% off usage rates for e-billing and paying by direct debit $2,635incl. conditional discount
Alinta Energy Fair Go 35 35% $2,680

*Estimated annual costs based on a yearly gas usage of 27,620 (units), as of April 2022. Gas prices based on gas provided through the ATCO network. Discounts shown apply to gas usage charges only.

What else impacts WA gas costs?

In addition to daily supply and gas usage charges, the other cost to be aware of is a daily account service fee. Most WA gas suppliers charge this fee, which is between 4c and 8c per day on top of your supply and usage costs.

What about electricity providers in WA?

All residential electricity customers in Western Australia are supplied by either Synergy or Horizon Power. While competition is thriving in the gas market, Synergy remains the only electricity retailer for households in the Perth area, while other parts of the state are covered by Horizon Power. Electricity competition in WA is still restricted, so these two retailers have almost identical pricing. Big businesses have several retailers to choose from.

Where is natural gas supplied in WA?wa gas map

Our customer satisfaction ratings are based on the feedback of natural gas customers, rather than those who purchase bottled LPG. To connect natural gas to your home or business, you must live in an area with reticulated gas mains. As you can see from the map (right), supplied by the WA Department of Finance, natural gas is only available in the most populated regions of the state, including the areas surrounding Perth, Busselton, Gingin, Albany, Kalgoorlie-Boulder, Geraldton, Mullewa and Carnamah.

Alinta Energy services all of the highlighted areas in the map, while Kleenheat, Origin, AGL and Simply Energy can only service the regions along the western coast, from Busselton to Geraldton, which includes the greater Perth area. In Kalgoorlie-Boulder and Albany, Alinta is the only residential natural gas provider. If natural gas is not available to your property, a gas supplier may be able to arrange a quote from the network operator to extend the gas mains to your home or business. However, this is only practical if the property is already near a gas network. Alternatively, If the property is in a remote area, the only option is bottled LPG. Kleenheat, Alinta, AGL and Origin operate LPG services in some areas.

WA Gas Prices

Gas prices in Western Australia remain regulated by the state government for small usage customers. A customer is considered to be ‘small use’ if the property uses less than 1 terajoule (TJ) of natural gas per annum. This realistically includes all households and most small businesses. This means the providers are set a limit as to what they can charge customers.

The price of natural gas in WA is predominately made up of supply and usage charges:

  • A supply charge is a daily fee for being connected to the mains gas network and applies regardless of whether or not the property uses any natural gas
  • Usage charges are incurred for the natural gas used. These charges are provided in terms of ‘units’, with one unit equating to about 3.6 megajoules of gas – equivalent to 1kWh of electricity
  • It’s also common for gas suppliers to charge a daily account service fee in WA. This is typically between 4c and 8c per day

Customers in the Kalgoorlie-Boulder and Albany areas of WA are charged a standard flat rate for their natural gas usage. But customers in Mid-West/South-West WA (i.e. Perth, Geraldton, Carnamah and all the surrounding areas) are typically charged in block usage rates. Under this pricing structure, customers receive one rate for the first 12 units (43.2 MJ) of gas used per day, and a lower rate for any additional gas usage beyond that. To put that into perspective, the average gas oven will use around 12 megajoules an hour.

Below we have listed the natural gas prices for Alinta Energy, Kleenheat, AGL, Origin, Simply Energy and Perth Energy. As you will see, most gas retailers set their prices at, or very near, the maximum cap they are allowed to charge. However, these rates don’t factor in discounts, which will ultimately make the difference in terms of finding the overall lowest prices.

Where does natural gas come from?

Natural gas is produced and refined by large, international fuel companies, such as BHP Billiton, BP, Chevron, ExxonMobil, Santos, Shell and Woodside Energy. Most of Western Australia’s gas supply comes from the off-shore Carnarvon, Browse and Bonaparte basins. Once it’s extracted, the gas is transported to mains gas systems across the state via high-pressure gas pipelines.

The natural gas mains system in WA is operated and maintained by ATCO Gas Australia (formerly WA Gas Networks). This is who you should contact if anything goes wrong with your gas supply, or in case of an emergency, such as a gas leak. ATCO is responsible for meter readings and passes this information onto your energy retailer for billing purposes. Your retailer – be it Alinta, Kleenheat, Origin, AGL or Simply Energy – will then bill you for your gas usage and collect the additional supply charges on behalf of ATCO.

Natural Gas for WA Businesses

Kleenheat, Origin, Alinta Energy, Simply Energy and AGL sell natural gas to business customers. Medium to large businesses have a few extra options as Synergy and Perth Energy retail natural gas to customers consuming at least 180 gigajoules (GJ) of gas per annum, or about $6,000 per year. Businesses that don’t use this much gas will remain limited to the options we’ve just mentioned. While natural gas prices are only regulated for customers consuming less than 1 TJ of gas per annum, large businesses in WA are free to negotiate rates with their retailer.

What’s next for the WA energy market?

The Western Australia government has allowed competition in the residential gas market for years, yet only recently have things really started to heat up. As mentioned, Simply Energy, AGL and Origin have recently joined the WA natural gas market, while another retailer, Perth Energy, offers a standard contract and could soon place more emphasis on attracting residential customers.

AGL, Simply Energy, Origin and any other potential newcomers will have their work cut out for them to secure a foothold in the WA gas market as prices remain regulated and there is therefore minimal difference in terms of what customers actually pay. However, the large discounts (conditional or otherwise) now being offered are proving the main point of difference.

Our survey of WA gas customers found that a clear majority (65%) are happy with their existing gas suppliers and don’t want to switch. Almost a third (28%) of Western Australians chose a gas provider based on name recognition, with 29 per cent opting for a brand that offered the biggest discount.

Interestingly, our research found that natural gas customers in Western Australia are generally more satisfied with their service than customers in other states of Australia. However, with new retailers likely to join the residential gas market in the years to come, customers should regularly review their energy options and compare plans in their area. While WA gas prices remain regulated, the retailers can still compete to offer the best deals and service.

  • When it comes to electricity, it looks like Western Australia will not be opening up to retail competition for the foreseeable future, although market deregulation has been a political talking point of late.

Where can you find the best deal on gas in WA?

Given that the overall price you pay for power will likely be determined by the size of the discount you receive, it’s important to look for other value-add incentives when it comes to picking the plan and provider that’s best for you. As mentioned in this report, all of the gas retailers in WA have some point of difference in the market, whether that’s because they have a rewards program which delivers savings on something that interests you, or because they offer additional perks like movie tickets.

The point is that it’s important to make your decision based on several factors, which should include how that retailer is rated by its existing customers. And that’s where our annual review can help.

Important Notes

Canstar Blue surveyed 12,000 Australian adults across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by Qualtrics. The outcomes reported are the results from customers within the survey group who live in Western Australia, have a gas account, and pay the bills – in this case, 616 people.

Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then by mean overall satisfaction. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criteria.
