Rebuild the bill from unit rate, standing charge and use
Household energy tools are useful when you can see whether the unit rate, the standing charge or the kWh is driving the total. Compare a current bill with a cap or solar scenario on the same usage, not on a headline unit price alone.
- Enter usage from a recent bill (kWh or cubic metres) rather than a round guess.
- Keep standing charges in the same units as the calculator (often pence per day).
- Test a second usage level if the household pattern is about to change.
Usage, unit rate, standing charge
This hub brings together the energy tools currently available for ZA visitors. Start with the calculator closest to your question, enter figures that reflect your own situation, and compare more than one scenario when the decision is important.
The tools show the maths implied by the inputs. They do not replace provider quotes, professional advice, or country-specific rules that are not shown in the calculator. Review the assumptions beside each result before using it to make a decision.
