How do we calculate the cheapest electricity and gas plans in Sydney, NSW
Our energy comparison database determines the annual estimated cost of each electricity and gas plan, accounting for the following in real-time:
- Usage rates: The rate paid (in c) for every kWh of electricity or megajoule (MJ) of gas used.
- Supply rates: Fixed daily cost paid to maintain a connection with the grid (for electricity) and/or the gas mains.
- Estimated annual usage: The estimated annual energy usage of a residential customer living within the Ausgrid network (for electricity) and the Jemena Gas network (for gas). This figure currently sits at 3,900 kWh for electricity customers on a single-rate tariff and 18,200 MJ for gas customers.
- Discounts: Guaranteed discounts are accounted for, including the length of their benefit periods (the duration the discount applies to).
For electricity, each plan’s annual estimated cost is compared to the reference price — this is usually indicated as a percentage difference on our journey’s results page.
The NSW reference price for electricity, also known as the default market offer (DMO), is a price cap set by the Australian Energy Regulator (AER), protecting customers from overpaying for their electricity. Currently, NSW’s reference price sits at $1,965/year.
Each plan is sorted according to its annual estimated costs, starting with the cheapest. Do take note that our journey’s results are limited to three tariff types. A tariff determines how a customer is charged for their energy use:
- Single-rate tariffs for electricity plans, where usage rates are fixed regardless of the time of day.
- Flat-rate (identical to a single-rate tariff) and block rate tariffs (where gas is measured in ‘blocks’ of usage, with each one priced differently) for gas plans.
Other tariffs in Sydney include:
- Time of use tariff (electricity only): Usage rates differ between different hours of the day, where rates are higher during peak periods and cheaper during off-peak periods. To access this tariff, you must have a smart meter installed.
- Controlled load tariff (electricity only): You can nominate an energy-intensive appliance to be metered separately at a cheaper rate — provided you limit its hours of operation. You must also have a smart meter installed to be eligible.
If you’re interested in viewing other tariffs and their rates (if applicable), click on the ‘view rates’ prompt.
Otherwise, you can shop around on our database’s cheapest energy plans based on your latest gas or electricity bill information and your existing plan’s tariff:
- On our journey’s results page, select the ‘billing information’ prompt.
- Select the tariff matching your current plan.
- Pre-fill your bill information in the relevant fields.

What to consider with the cheapest electricity and gas plans in Sydney, NSW
Bundled electricity and gas discounts
A provider who sells electricity and gas plans may entice customers with a bundling discount. However, signing up for an electricity and gas plan from two separate providers could be cheaper. Run the numbers for both options first before choosing the cheaper one.
Your electricity and gas use
When you use the most electricity
- If you use more electricity during off-peak periods, a time-of-use tariff or demand tariff will save you more, as it charges lower usage rates during those hours.
- If you use more electricity during peak periods, a single-rate tariff is cheaper, as it charges you lower usage rates during those hours.
- If you have a power-hungry appliance, a controlled load tariff will save you more.
How much electricity or gas you use
- If you don’t use a lot of electricity, a plan with lower supply rates will save you more in the long term, as it forms the bulk of your power bill.
- If you don’t use much gas, a flat rate tariff is cheaper than a block rate tariff, where low volume use is charged at a lower rate.

Contract length and expiries
With energy plans, there are two types of contracts — ongoing and contracts with a fixed contract length.
Ongoing plans don’t have an expiry date, permitting you to switch providers or plans at any time.
In comparison, plans with a fixed contract length have a set expiry. Exiting early will result in penalty fees.
Once your plan passes that date, you’ll be automatically moved onto your provider’s standing offer (for electricity) or standing contract (for gas)
Standing offers and contracts in NSW adhere to that state’s reference price, which usually reflects the highest price retailers are willing to charge. They also don’t offer any value-added features (e.g. bill credits, guaranteed discounts).
If you’re currently on a standing offer or contract, that means you’re set to pay hundreds of dollars more than you should annually.
You can determine a plan’s contract length under the ‘contract details’ section on its BPID, which is accessible through the ‘basic plan information’ prompt on our journey’s results page or the ‘plan details’ prompt under each plan.
If your preferred plan has a fixed contract length, we strongly encourage you to add a calendar reminder to switch energy plans days before it is set to expire.
Variable vs fixed rates
The majority of energy plans are variable-rate plans — that means they can change, irrespective of whether your plan is ongoing or has a set expiry. However, your retailer must notify you in writing at least five business days before any scheduled changes.
If the cheapest energy plans in Sydney are variable rate plans, their annual estimated costs may change frequently. It’s important to keep track of all written correspondence (e.g. emails) from your provider.
Some providers offer fixed-rate plans with rates frozen over a fixed contract length (e.g. 12 months). However, fixed-rate plans are not common.
An energy plan’s rate type can be found under the ‘Billing and price details’ section in its BPID.
Hidden fees
Before switching to another plan, be aware of any hidden fees (e.g. disconnection/connection and exit fees) on your current plan’s BPID.
