Dispute checklist

The checklist updates with the strongest checks for your bill variance.

  • Confirm the opening and closing meter readings for the billing period.
  • Compare the tariff class and meter type with your account details.
  • Keep a copy of the bill, payment receipts, meter photo, and tariff notice.

Methodology

The calculation method rebuilds the bill from your tariff inputs, then compares the result with the actual bill.

  1. Energy charge = kWh consumed x tariff per kWh.
  2. Taxable base = energy charge + fixed charge.
  3. VAT or tax = taxable base x tax rate.
  4. Expected bill = energy charge + fixed charge + tax + arrears.
  5. Variance = actual bill - expected bill. Positive values suggest a possible overcharge.

Source and freshness

Use current local records. The page is not a live tariff database and does not claim official bill approval.

  • Source data: your bill, meter token receipt, account statement, and published tariff notice.
  • Official check: confirm tariff changes with your electricity distributor, utility authority, energy commission, or regulator.
  • Freshness note: reviewed 16 May 2026. Update the tariff, tax, and fixed charge whenever your provider changes rates.

Disclaimer

This tool is an estimate only. It does not replace the utility's official account ledger, a licensed meter test, regulator decision, or legal advice.

  • Tiered tariffs, demand charges, subsidies, estimated reads, penalties, and connection fees can change the bill.
  • If the variance is material, request the detailed billing calculation before paying a disputed amount.
  • For disconnection risk or safety issues, contact the utility or regulator directly.
