How to Find the Best Energy Provider in NSW

Choosing an energy provider in NSW is similar to other states, but local factors matter. Here’s how to start:

1. Use Comparison Websites

Websites like Energy Made Easy allows you to:
•    Compare rates for your area.
•    Check discounts, rewards, and feed-in tariffs.
•    Filter providers by customer reviews, contract length, and green energy options.

2. Your Usage

If you don’t have a past electricity bill to refer to, you can estimate your household usage based on a few simple details:
•    Home size: For example, the number of bedrooms and bathrooms.
•    Number of people living in the home: More residents usually mean more energy use.
•    Appliances and devices: Such as air conditioners, heaters, ovens, and everyday electronics.
Most comparison websites allow you to select these household details. Just fill them in, and the site will automatically estimate your average monthly and yearly electricity costs. This way, you can get a fairly accurate idea of what you’ll likely pay before choosing a provider.

3. Consider Your Priorities

Price matters, but it’s not the only factor when choosing the best energy providers in NSW. Here’s what to focus on and how it can impact your bill:
•    Customer Service: 73% of customers consider experience an important factor when choosing a provider (PwC).  The community and customer needs better, leading to higher satisfaction.  
Sumo Energy puts customers first, making high-quality service their top priority. With a local customer centre in Australia, Sumo staff deeply understand their community and customers’ needs, providing attentive and personalised support. Most Sumo customers report high satisfaction with the service they receive, reflecting the company’s commitment to a customer-first approach. 

•    Pricing Structure: It’s important to understand both daily supply charges (the fixed cost per day) and usage charges (cents per kWh). 
For example, to help you quickly compare electricity costs across NSW distributors, here’s the latest pricing for Sumo Sunrise Residential Electricity. These figures show how much customers may save compared to the reference price, along with estimated annual costs based on typical household usage. Your actual bill will vary depending on your usage and location.

Note: 
•    These estimates are rounded to the nearest dollar or percentage and based on typical annual consumption for each distribution zone. Actual bills will differ depending on household usage and timing.
•    Energy plans and pricing can vary, so checking the latest information is recommended.
 

Cheapest Electricity Providers in NSW 2025

Finding the cheapest electricity in NSW isn’t always straightforward. Pricing structures vary widely between providers, and the “cheapest” plan for one household may not suit another. Many retailers offer huge credit discounts, which can look very tempting at first, but your bills may increase once the promotion period ends.
That’s why it's important to look beyond the headline price, such as consider your household’s usage, check both the daily supply charge and usage rates, and always read the fine print. A plan that looks the cheapest upfront isn’t always the most cost-effective or reliable in the long run. Customer service, billing transparency, and how easily you can get help when you need it also matter. There’s nothing worse than being stuck on hold when you have a billing question or an issue with your meter.
Sumo currently supplies electricity across areas covered by the three main distribution networks in New South Wales. This includes suburbs within the Ausgrid network (such as Sydney, the Central Coast and the Hunter Region), the Endeavour Energy network (covering Western Sydney, the Blue Mountains, the Southern Highlands, Illawarra and the South Coast), as well as communities across the Essential Energy network, which services a wide range of regional and rural areas throughout NSW.
The cheapest plan isn’t always the best fit. It’s worth choosing a provider that offers clear pricing, reliable billing, and helpful support.  With Sumo’s Australian-based customer service team, you’re speaking to people who understand how local households in NSW actually need. So when you have a question or need help, you’re talking to someone who truly gets it.
