Cheapest gas rates in Adelaide by retailer

Are you paying too much for gas in Adelaide?

In South Australia, the average annual gas bill in 2023 was $1,186. And the typical gas home uses 22,321 MJ each year. You should also know, that unlike electricity where regulations require energy providers to cap prices at a default offer, gas retailers are free to charge what they want. As a consequence, there is a significant gap between the cheapest gas plans available in Adelaide and the most expensive.

How much can you save by switching gas providers in Adelaide?

According to the Australian Energy Regulator’s 2022-23 Annual report “Savings are available for customers who move.” Average households in South Australia could save $284 on gas per year by switching from the most expensive standing offer to the cheapest market offer*. Of course, almost 90% of SA gas households are already on market offers, but that is no guarantee they are on a good deal. Switching from the worst market offer to the very best gas deal would save as much as $292 a year*. So, if you are shopping for the cheapest gas in Adelaide, there can be real savings on offer.
