The cheapest snapshot is not always the best risk choice. Compare unit rates, standing charges, term, exit fees and how you use energy.
A fixed tariff fixes specified rates under its terms, not the number of kWh or the total bill.
Fixed
Rate certainty for a term; check exit fees and what is actually fixed.
Variable
Rates may move and default tariffs may be cap-protected where eligible.
Time of use
Savings depend on measured use within cheaper windows.
Compare
Use annual kWh and all fixed charges, not a promotional monthly estimate.
Frequently asked questions
Does fixed mean a fixed monthly bill?
No. The price per unit may be fixed, while the total changes with use.
