Do I have to pay to switch energy providers in SA if I use Mozo?  

Our energy comparison tool is free to use and if you decide to switch SA gas or electricity providers using our service in most instances you won’t have to pay anything.

How often are energy plan details updated on Mozo? 

We receive energy plan information direct from each SA energy provider so you can be confident that the information you see on our website is accurate and up to date. 

Does Mozo compare all energy providers in South Australia? 

The number of energy providers that you can compare will depend on where you live in South Australia as not every retailer will service the whole state. We don’t compare every provider that operates in South Australia but we will be able to provide you with a listing of providers that service your area, so that you can compare their plans. We compare both big retailers like EnergyAustralia, Origin Energy through to smaller players like Dodo and Commander power and gas

There isn’t one best energy provider or plan available in South Australia as everyone’s energy needs are different. The best plan for you could be very different to your neighbours, which is why it is important to do a comparison check for yourself, to see which energy provider is best for you.

How to compare energy rates in South Australia

If you live in South Australia or are planning to move to the festival state, you have plenty of energy providers to choose from. Instead of being stuck with high energy bills, you have the power to switch to a more cost effective plan whenever you want.   

Every energy plan in South Australia are made up of two key charges:

  • Supply charge: this is the cost that an energy provider will charge you to supply your home with electricity or gas. This is usually a fixed daily charge. 
  • Usage charges: as the name suggests this is the rate that you pay for every kwh of energy you use. This is a variable cost as you can use more or less energy depending on your habits or home’s requirements. 

Mozo exists to make comparing energy plan rates easier. We can help you shortlist energy plans in your SA suburb with just a click of a button. All you need to do is enter your postcode into our free comparison tool and tell us a bit about your usage habits and preferences and we’ll be able to give you a listing of some of the plans that are available in your area.  

To compare energy rates between energy providers, it is a good idea to have a recent energy bill handy. This will mean that you can enter in your exact usage and we’ll then be able to give you a more accurate rate quote for each plan to compare against. 

Checklist to help find a good SA energy plan 

All energy providers in South Australia will offer a number of incentives to attract you to their energy plans. Here is a quick checklist that you can consider when you are picking a new energy provider.  

  • Sign up offers. Many energy retailers will have ‘sign up’ offers for new customers such as “get $50 off your first bill” or “10 free movie tickets”. But you need to make sure the continuing tariff is also the best because there is no use of getting a one time discount and then paying extra every subsequent quarter.
  • Conditional discounts. Often energy providers have conditional discount offers such as a pay on time discount for every bill that is paid on time or a discount when you pay by direct debit. You need to weigh up these offers to ensure that you can meet these on an ongoing basis, otherwise you could be better off with a standard plan.   
  • Sustainable energy. There are a number of energy providers in South Australia that have green energy plans or options for you to pick a plan that generates some or all of the energy using renewable sources. 
  • Bill smoothing. If you find it difficult to pay one large chunk of money every quarter to cover your energy bill, some energy providers in SA have the option of splitting your bills in even instalments through the year. Just keep in mind that these instalments are often ‘estimated’ at the beginning of your plan so you should keep a check just in case there is a gap between the predicted amount and your actual spending. 

Who is the cheapest energy provider in South Australia?

There isn’t one provider that is the cheapest for every South Australian because every home is different and so is our energy habits and preferences. 

Here at Mozo, we understand that while we all want cheaper energy bills, sometimes there are other factors that are also important when choosing a new electricity supplier, like whether they have good customer service or a commitment to renewable energy generation. We collect energy customer reviews of South Australian energy providers, so you can read these before you make your choice.

Is it cheaper to use the same provider for gas and electricity in SA?

There are many energy retailers servicing South Australia, and while you can often get discounts for having your gas and electricity with the one energy provider, this might not necessarily be the cheapest option. 

We can help you to compare bundled energy plans and also stand alone gas and electricity plans, so get a recent bill handy and punch in your postcode into the tool to get started. 

Who is the best energy provider in South Australia?

Just as there isn’t a cheapest energy plan for every South Australian household, there also isn’t  one best energy provider. The best provider for you and your home will depend on a number of factors including your household usage, the time of usage, type of usage and your location. 

There are also other factors that you should weigh up when choosing an energy plan. If price is your biggest consideration, then the best plan will be the cheapest one. But these days, more Australians are placing importance on social and environmental factors and choosing an energy provider based on whether they generate energy via renewable sources or offer green energy plans.  

Each year, Mozo’s team of energy experts conduct the Mozo Experts Choice Energy Awards where they compare the plan costs of all providers in our database and award those in South Australia with the best value plans. 

Then there’s the Mozo People’s Choice Household Awards, and this is where we ask Australian consumers to rate their energy provider on a number of criteria. We tally up the results and award those energy providers that are voted best by their customers.  

Moving to SA - what you’ll need to set up a new energy plan

Moving can be stressful but you don’t want to get stuck on a dud energy plan just because you ran out of time and just called up the first SA energy provider you saw advertised. 

We realise you won’t be able to give us information from a previous energy bill, but we can still tailor our search results to give you an estimate of your energy costs and plans that will be available in your new suburb. 

For a detailed rundown of everything that  you will need when you move house, check out our moving house guide. But to get started, here are the things you’ll need to set up a new account:

  • Exact property details and SA postcode
  • Personal details for setting up account, including identification

If you are moving from SA to another state in Australia, you can find details of plans and key info on our site:

Ways to reduce your energy bill 

One of the most obvious ways for reducing your energy bill is to reduce the amount of energy you are using at home. This might take some effort on your part, but there are a number of innovative ways in which you can try to introduce more energy efficient habits in your home. 

  • Power down: don’t keep computers or tvs on standby power. And when you are not using appliances like the kettle or toaster turn them off at the powerpoint. Switch off lights, fans, heaters and aircon in rooms when you are not in them.
  • Fill the gaps: small cracks around windows and door frames can mean higher heating and cooling costs. Seal up any gaps and use door snakes across doorways to stop cold or warm heat escaping. 
  • Do full loads: not only will this also help you to save water, but doing full loads of washing and making sure that the dishwasher is full each time you put it on can help you reduce your bill.

If you need some additional ideas, head on over to our energy savings tips hub. 

The other way to lower your gas and electricity bills is to compare the energy providers in SA and switch to a retailer that’s offering a better deal. Check out the different deals and discounts and then work out if you can save money on a more competitive deal.

How much does energy cost in SA?

The tariff you pay for your energy usage will depend on multiple things like where you live in South Australia and how much energy you are actually using. Your bill will then be calculated based on:

  • Fixed supply charge. This is a fixed price that you need to pay per day for your service
  • Usage. This is calculated per kilowatt hour of usage     

Can I switch energy plans if I am renting? 

If you are responsible for paying the gas or electricity bill at your rental then you are able to switch energy plans to find one that will be best for your circumstances.

If electricity or gas is included in your rent then it is your landlord’s responsibility to choose and manage the energy plan at the property. 

How long does it take to switch energy providers in SA? 

Switching providers in itself does not take much time and can mostly be arranged online or over the phone. But when you receive your first bill from the new provider depends on when your meter was last read. This can take anything from a few days to three months.  

If you are moving to a new house, you will generally need to give about 2-5 days of notice to your SA energy provider to move your account. Make sure they have access to your meter so that there is no delay in the transfer and you have gas and electricity set up before you move into the new property.    

Does it cost me anything to switch plans? 

You don’t need to pay extra money to energy providers in SA for switching your account if you are on an open contract. But if you have signed a fixed term contract, you might need to pay a termination fee for ending the contract before the planned expiry date. If you are moving premises, many energy providers in SA charge a connection fee for setting up the account and service to your new address. This cost is generally added to your first bill.

Little care factor

Owning a home that was not lived in for 4 months. Bill came in at approximately the same figure as when 4 people lived there. Trying to gain explanation of how this is possible proved to be of no use. No explanation could be provided, no daily usage report could be provided as its meter-read. Unfortunately for me, settlement was taking place the week i received the bill therefore further investigations couldn’t be made.

Latest Energy news


Last week, the Australian Capital Territory government announced it would be expanding its ACT Home Assessment Energy Scheme to renters. The ACT Home Assessment Energy Scheme is an initiative that provides free in-house energy assessments to discover areas where households can save on their energy bills. “It can be very hard for renters to make major energy-saving changes to their home. By expanding this program, we are able to provide renters with tailored information,”  said Minister for Climate Change and Sustainability, Shane Rattenbury. But while this is good news for renters in the ACT, it doesn’t mean the rest of the country should miss out on energy savings insights. So we’ve jotted down five energy saving tips for renters that can help keep costs down all year round.

Energy savings vdo to be extended to all vic customers

In July last year, the Victorian energy market went under intensive reform to improve prices and transparency for residents and was called the Victorian Default Offer (VDO).The VDO imposed a price cap on standing offers, which meant that retailers could no longer charge exorbitant prices for these energy plans. All previous customers on standing offer plans were then rolled onto the VDO. This week the Essential Service Commision (ESC) announced that from 1 September 2020, it will be extending the VDO to energy customers living in embedded networks, like caravans, retirement villages and even small businesses. According to the ESC, more than 104,000 customers will benefit from this reform. “Embedded network customers have not been fully covered by the same price protections as other Victorians. This ensures they now have access to a fair deal with significant savings for some,” said ESC pricing director, Marcus Crudden. Crudden said customers within embedded networks are expected to save between $180 to $360 annually, while small businesses could see savings of between $900 to $2,220.

Energy prices which retailer offers the cheapest electricity plan

Within the next few weeks, many Aussie households are expected to receive their latest energy bill. And for some, it won’t be good news. In fact, according to Mozo research the average household is expected to fork out an extra $88 a month due to an increase in electricity usage because of the Covid-19 lockdown. But there may be a silver lining on the horizon, as many retailers are acknowledging the financial strain the Covid-19 pandemic has had on Aussie wallets by announcing price decreases. On 1 July 2020, close to 20 retailers announced they would be cutting the electricity prices for customers located in either New South Wales, South Australia, South-East Queensland or the Australian Capital Territory. And in some instances, retailers have vowed to cut prices in all three states, like Powershop. “We are pleased to be able to bring some much needed relief to households in NSW, SE-QLD and SA, especially during winter and given many of our customers are spending more time at home, which may lead to higher power bills,” said Powershop CEO, Jason Stein. “Our existing residential customers saw our prices decrease on average by approximately 14.2% in South Australia, 8.7% in New South Wales and 7.5% in South East Queensland.” Other retailers cutting prices across NSW, SE-QLD and SA included energy giant, Origin Energy, Simply Energy and newcomer, Kogan Energy.

Energy bill anxiety how to keep costs down this winter

While things might be a little different to this time last year, one thing that hasn’t changed is the winter chill. And unfortunately, as a large number of Aussies spend the majority of their time indoors, a jaw-dropping energy bill is to be expected. According to recent data by energy company Jemena, our electricity usage has jumped by 16% compared to this time last year, while businesses experienced a fall in electricity usage of between 10% - 12%. With Aussies having to tighten their wallets to manage expenses during the pandemic, a higher bill is far from ideal. According to Professor Sara Wikinson at University of Technology Sydney, some households are doing everything they can to soften the blow. She said that older Aussies are reducing their consumption by either cutting back their use of heating appliances, going to bed fully clothed or even skipping showers. "People are spending almost all their time at home, which is obviously pushing up their energy consumption. And [their] ability to hang out somewhere warm in the mall or community centre has gone," Wilkinson said. However, Powershop chief executive Jason Stein said that drastic measures are not always necessary and that simple savings can be made around the home. “With Australians spending more time at home this winter, energy bills may be higher. [But] there are some simple things you can do to try and keep your energy bills down and help save money,” Stein said. He recommended setting “your heater thermostat between 18–20°C in living areas, [as] every extra degree adds 10% to your heating bill.”“Switching off the game console after use could save a household of four up to $193 a year,” Stein said. Other tips include ditching your dryer for a clothes horse, investing in door snakes to plug draughts and improve insulation. And remember to switch off lights when you leave a room. If you’d like more energy savings tips that’ll not only keep you warm but keep costs down this winter, head on over to our energy savings tips hub!
