Sydney energy prices can vary significantly from one suburb to the next, even when you’re buying the same type of electricity or gas. That’s because what you pay is influenced by your network area, your tariff, your meter type, and the plan structure your retailer offers. If you’ve been trying to compare offers yourself, it can feel like you’re comparing apples with oranges.
This guide explains how to compare energy providers in Sydney in a way that makes sense for both households and businesses in NSW. If you want a faster outcome, Zembl can run an obligation-free comparison across our panel of retailers and manage the paperwork if you decide to switch.
Why comparing energy in Sydney is different to other cities
In the National Electricity Market (NEM), NSW customers generally have choice of retailer, but your local distributor still impacts the tariffs available to you and a large part of your bill. In Sydney and greater NSW, your network area is typically one of the following:
- Ausgrid (many Sydney metro areas)
- Endeavour Energy (parts of Greater Western Sydney, Blue Mountains, Illawarra, Southern Highlands)
- Essential Energy (regional NSW)
Retailers set the retail component of your pricing, but network charges, metering costs and tariff structures can make two “cheap rates” offers perform very differently once applied to your actual usage profile.
What to gather before you compare energy providers
To compare plans accurately, start with your most recent bill (or ideally the last 12 months). Key items to look for include:
- Meter type: basic/accumulation, smart meter, interval meter
- Tariff type: single rate, time of use, controlled load, demand (common for many businesses)
- Distribution/network area: often listed on the bill
- Usage: kWh for electricity, MJ for gas, plus when you use energy if you’re on time of use
- Supply charge: daily fixed charge, which can heavily influence outcomes for low-usage sites
- Contract details: end date, benefit period, price change clauses and exit fees (if any)
How to compare electricity providers in Sydney
When you compare electricity plans in Sydney, focus on total bill outcomes, not just one headline rate.
1) Compare supply charge and usage rates together
A plan with a slightly higher usage rate can still win if its daily supply charge is lower, especially for small premises, cafés, small offices and households with modest consumption.
2) Check if you are on single rate or time of use
Time of use pricing can be beneficial if you can shift consumption away from peak periods, for example, running dishwashers, pool pumps or EV charging overnight when off-peak applies. It can also increase costs if most of your usage happens during peak.
3) For businesses, review demand and network tariff suitability
Many Sydney businesses are placed on demand-based tariffs or network tariff structures that may not suit how the site operates. A competitive retailer rate does not always fix an unsuitable tariff. A good comparison should include a tariff check, particularly for:
- multi-meter or multi-site operations
- sites with large equipment start-up loads
- venues with strong peak usage patterns (hospitality, gyms, cold storage)
4) Confirm the benefit period and what happens after it ends
Many market offers include conditional discounts or introductory benefits. Compare the ongoing rate you’re likely to pay after the benefit period, not just the first few months.
How to compare gas providers in Sydney
Not all Sydney properties have gas, but for those that do, the best gas plan depends on your usage and whether you want to bundle electricity and gas with one retailer.
When comparing gas, check:
- Supply charge and usage rate (MJ)
- any dual fuel incentives, if you also take electricity
- fees that may apply for moving, closing or changing accounts

Use Energy Made Easy and know what it can and can’t do
For households and many small businesses, the Australian Government’s Energy Made Easy comparison site can be a useful starting point. It is independent and can help you see generally available market offers for your area.
However, it may not reflect every negotiated outcome available to businesses, and it won’t do a tariff suitability review for complex sites. If your bills are large, you have multiple meters, or you manage multiple locations, a broker-led comparison can be more practical.
Common mistakes people make when comparing Sydney energy plans
- Comparing only cents per kWh and ignoring supply charges and tariff structure
- Overlooking controlled load (for some homes) or demand charges (for many businesses)
- Missing contract end dates and rolling onto higher standing offers
- Not accounting for how usage changes, for example, longer trading hours, new equipment, or seasonal cooling loads
- Assuming the same plan works across every Sydney suburb, network area matters

Frequently asked questions
Who is the cheapest energy provider in Sydney?
There is no single cheapest provider for everyone because the best plan depends on your network area, tariff and when you use energy. The cheapest offer for a household with off-peak heavy usage can be different to the cheapest offer for a small office on a single rate tariff.
Can I have one provider for both electricity and gas in Sydney?
Often yes, and bundling can simplify billing. It is still worth comparing the combined outcome because a “dual fuel discount” does not always deliver the lowest total cost.
Will switching energy providers interrupt my supply?
In most standard switches, your electricity and gas supply stays on. The retailer changes, but the physical network supplying you remains the same.
How often should I compare plans?
Many customers review at least annually, and businesses with larger spend often review before contract end dates, after major operational changes, or when market conditions shift.
