Sydney households and small businesses have plenty of choice when it comes to electricity retailers, but “cheap” rarely means the same thing for everyone. The best value plan depends on your tariff type, your postcode, how you use energy through the day and whether you want a greener option.
This guide explains how electricity pricing works in Sydney, what to compare (beyond headline discounts) and how to switch providers smoothly. If you want someone to do the comparing for you, Zembl can review your bill and shortlist options across our retailer panel, then manage the switch end to end.
Why it’s worth comparing electricity providers in Sydney
Retail prices change regularly. Even if you have not moved house, your rates can creep up when an old benefit period ends or a retailer refreshes their offer structure. Comparing your plan at least once a year can help you:
- Reduce your total bill by lowering both the usage rate (c/kWh) and the daily supply charge.
- Match the plan to your lifestyle, for example time-of-use for households that can shift usage away from peak periods.
- Avoid poor value “discount” offers that look good in ads but do not stack up once supply charges and conditions are included.
- Choose greener electricity, including plans that add GreenPower or carbon offset options.
How electricity prices work in Sydney (NSW)
In Sydney, you buy electricity from a retailer, but your poles-and-wires distributor still matters. Most Sydney metro customers are on the Ausgrid network, while parts of Greater Sydney may be on Endeavour Energy. Your distributor influences network charges and can affect which tariffs are available.
The three big parts of your power bill
- Usage charges: what you pay per kWh, sometimes split into peak, shoulder and off-peak rates.
- Daily supply charge: a fixed cost per day to stay connected, regardless of usage.
- Other charges and features: fees, credits, conditional discounts and any green add-ons.
Tariffs you’ll commonly see in Sydney
- Single rate: one usage rate all day, typically simplest to compare.
- Time-of-use: different rates depending on time, can suit people who run major appliances outside peak times.
- Controlled load: separate cheaper rate for appliances like electric hot water, if you have the right meter setup.
If you are unsure which tariff you are on, it will be listed on your bill. Tariff fit is one of the biggest drivers of whether a deal is genuinely cheap for you.
What to compare when you’re chasing a cheaper deal
To find a cheaper electricity plan in Sydney, compare offers on total cost, not just the advertised percentage discount.
1) The supply charge
Plans with a very low usage rate sometimes make up for it with a higher daily supply charge. This can be poor value for low usage households and many apartments.
2) Your effective usage rate
For time-of-use plans, compare peak, shoulder and off-peak rates, then consider how your household actually uses energy. A cheap off-peak rate does not help if most of your usage happens during peak periods.
3) Benefit periods and conditions
Some offers include conditional discounts that require on-time payment or direct debit. Also check whether the best rate only applies for the first 6 to 12 months.
4) Contract terms and exit fees
Many market offers are no lock-in, but not all. Always confirm contract length, notice periods and whether any fees apply.
5) Solar feed-in tariffs (if you have solar)
If you export solar to the grid, the feed-in tariff can materially change your annual costs. It is worth comparing solar-friendly plans rather than treating the FiT as an afterthought. If you want a deeper solar comparison, see our guide: compare solar energy plans NSW.
How to compare electricity plans in Sydney step by step
- Grab a recent bill, ideally covering a normal month, and note your usage, current tariff and meter type.
- Confirm your network area, for example Ausgrid or Endeavour Energy, as that impacts tariff availability.
- Compare on estimated annual cost, not just individual rates. A plan can have a cheaper headline rate but a higher annual bill for your usage.
- Check plan rules like benefit periods, late fees, paper bill fees and pay-on-time conditions.
- Switch and diarise a review 10 to 12 months later, so you can re-check the market before any promo period ends.
Switching electricity providers in Sydney, what to expect
Switching retailers is usually straightforward. Your power supply does not get turned off, the change is mostly administrative and the distributor continues to deliver electricity to your premises. Timeframes vary, but many switches complete within a few business days once your new retailer has processed the request.
Before switching, confirm:
- your current contract end date and any exit fees
- whether you need to keep the same tariff type
- billing preferences (email bills, direct debit, etc.)

Residential vs small business plans in Sydney
Residential plans are generally standardised and easier to compare. Small businesses may have additional complexities, including different metering, higher load factors and more opportunity to optimise tariffs. If your business is growing or you operate multiple sites, a structured review can often unlock savings beyond a simple switch.
For gas users, bundling is not always the cheapest path, but it is worth checking. Related guide: best gas supplier NSW.
Greener electricity options in Sydney
If you want a cheaper deal and lower emissions, you can compare:
- GreenPower add-ons (government accredited renewable energy certificates on top of your usage)
- Carbon offset options on some plans
- Solar optimisation, especially if you can self-consume more of what you generate
Cheaper energy and lower emissions often go together when you pair a better plan with usage reduction. See: NSW electricity comparison and our solar guide above.
FAQs
Who is the cheapest electricity provider in Sydney?
There is no single cheapest retailer for every household at all times. Pricing changes frequently and the cheapest option depends on your usage profile, tariff type and postcode. A bill-based comparison is the most reliable way to identify the best value plan for you.
Is it safe to switch electricity providers?
Yes. Your distributor continues to supply electricity, so switching retailers does not affect the physical delivery of power. The main difference is who bills you and the rates you pay.
How often should I compare electricity plans?
A good rule is every 12 months, or when a benefit period ends. It can also be worth reviewing after major household changes like adding air conditioning, buying an EV or installing solar.
Do I need to be home for the switch?
Usually no. In most cases the switch is completed without a site visit. If a meter change is required, your retailer or metering provider will advise.
