How we calculated these results

  • We used 4,000 kWh a year, a reference figure, because no usage was entered. Enter your usage for a personal estimate.
  • 74 plans are priced with an assumption we could not check (for example a demand charge or a time window we cannot place your usage in). They are listed after the others and marked as less certain.
  • Conditional discounts (such as paying on time) are left out of the ranking. Plans that have them show the lower figure separately.

Calculation version 1.0.0. Compared 6 October 2026. 393 plans matched. Data from Energy plans: Consumer Data Right (AER). Full methodology
