For the most part, there’s a trend of gas bills decreasing the older the customer is. This may be the result of customers being eligible for certain energy rebates or concessions, or gas consumption habits differing between age groups.
What impacts average gas bills?
Natural gas is fairly similar to electricity in that there are many factors that contribute to your overall costs. Before choosing a gas plan, it’s important to think about which features are most important to you. Here’s what you should consider:
- Usage charges: Some gas suppliers have set rates for all gas usage, while others charge gas usage in ‘blocks’, meaning prices will change depending on how much gas your household consumes.
- Supply charges: Gas supply charges are the underlying costs of supplying gas to your home via the gas mains network. Supply charges are generally the fixed price component of a gas bill.
- Hidden fees: Some gas suppliers may tuck fees away in the fine print, such as a connection fee, credit card surcharge, late payment fee, or a paper billing charge. This is why reading the details of your gas plan is important.
- Location: Geography plays a major part in the price of natural gas. Customers should consider the difference in supply and running costs, especially if you live in a regional area or have lower gas usage needs.
- Incentives: Whether it’s discounts or a rewards program, incentives are a great way for providers to compete for your business. It might even be a larger discount for bundling utilities with the same provider.

Can I get a better-than-average gas deal?
This will ultimately come down to your personal circumstances, but to cut a long story short, gas prices can change quite frequently, meaning there are always new deals popping up. By now you should understand that being complacent with an average gas bill will usually mean you’re not on the most competitive plan. To get a better-than-average gas deal, you’ll need to keep an eye on gas prices and be willing to switch if a better deal comes your way.
