But you’re not average, are you?

There are 122 gas plans available in Westleigh, New South Wales, and only one of them is the best-priced for you.

The generic 'best plan' assumes a reference consumption level, a generic load curve extrapolated annually, excludes incentives and welcome credits, and excludes solar, battery and EV from the ranking. Your bill has the real information - upload it here and I'll run a personalised comparison based on your unique combination of actual usage, tariff type and location. It takes about a minute to find out what's really the best plan for you.
