Fixed vs Variable Energy Tariffs Explained
In a volatile energy market, is it safer to lock in your tariff? We break down the pros, cons, and costs.
Compare Current TariffsOne of the most common questions we get is: "Should I fix my electricity rate?" It's a valid concern. With global energy markets fluctuating, the idea of price certainty is appealing. However, Fixed Rate tariffs are becoming rarer in Australia, and they aren't always the money-saver they appear to be. This guide explores the mechanics of both tariff types to help you decide.

1. Tariff Types Explained
Variable Rate Plans: The retailer can change your usage and supply rates at any time, usually with written notice. These track the wholesale market more closely.
Fixed Rate Plans: The retailer guarantees your usage and supply rates will not change for the duration of the benefit period (usually 12 months). Note: This is different to a "Fixed Cost" plan where you pay the same dollar amount every month regardless of usage.
2. Variable Rates: The Pros & Cons
- Pros: Historically cheaper than fixed plans. No exit fees. Greater flexibility to switch if prices drop.
- Cons: Prices can rise. If the wholesale market spikes (as seen in previous years), your rates will likely go up shortly after.
3. Fixed Rates: The Pros & Cons
- Pros: Budget certainty. You are immune to price hikes for the contract term. Peace of mind.
- Cons: Usually carry a "risk premium" (higher starting rate). If market prices drop, you are stuck paying the higher rate. Some may have exit fees (though rare now).
4. Head-to-Head Comparison
| Feature | Variable Rate | Fixed Rate |
|---|---|---|
| Starting Price | Generally Lower | Generally Higher |
| Price Stability | Low | High |
| Availability | Widespread | Limited |
| Exit Fees | None | Possible (Check T&Cs) |
5. Market Conditions 2026
In 2026, the energy market has stabilised somewhat. Most experts suggest that the premium you pay for a fixed rate is currently not worth the protection, as major price spikes are not forecast for the next 12 months. A competitive variable plan is likely to result in a lower total annual bill.
6. How to Choose
Choose Variable if: You want the lowest possible rate today and are willing to switch providers if they hike the price later.
Choose Fixed if: You are on a strict fixed income and cannot absorb a sudden 10-15% price rise during the year.
Final Verdict
For most Australian households, a competitive Variable Rate tariff with no lock-in contract offers the best value. Just remember to check your rates every 6-12 months. Have a look at our comparison tool to see what's available.
