Why do gas prices differ across New South Wales?
Gas prices in New South Wales vary for several reasons:
- Distribution network: Your local gas network's charges vary by region within NSW. Areas with older infrastructure or lower density may have higher network costs.
- Retailer margin: Each retailer adds its own margin to wholesale gas costs and network charges. Smaller retailers often offer sharper pricing to attract new customers.
- Plan type: Fixed-rate plans lock in your rate for a set period, while variable plans can change. Fixed plans offer price certainty; variable plans may start lower but can increase.
- Seasonal usage: Gas usage in New South Wales is typically higher in winter due to heating. Households on tariffs with usage tiers may face higher marginal rates when usage increases.
- Bundle discounts: Taking both electricity and gas through the same retailer can attract a discount. Always compare bundled and separate plans to verify the bundled option is the better deal.
