⚡Quick Answer / At a Glance

To audit your electricity bill, check 4 key numbers: 1) Current vs previous meter readings to verify actual units consumed; 2) Sanctioned load in kW to ensure correct fixed charges; 3) Tariff category (Domestic LT-I); and 4) Fuel surcharge (FAC/FPPCA) rate per unit. Meter reading errors and incorrect load categories are the two most common billing mistakes.

Meter Reading Check

Verify 'Actual' vs 'Estimated/Average' status

Sanctioned Load Check

Ensure you aren't overpaying on excess kW load

Multiplying Factor (MF)

For domestic meters, MF is always 1

4 Essential Items to Check on Every Electricity Bill

1. Meter Reading Status (Actual vs. Average): Check if the bill says "Actual" (Normal) or "Estimated / Average / Door Lock". If the meter reader couldn't access your meter, the DISCOM generates an average estimated bill, which can lead to huge accumulated adjustments next month.
2. Tariff Category: Ensure your bill says Domestic / Residential (e.g. LT-I, LMV-1, LT-2a). If it was mistakenly coded as Commercial (LT-II), you are paying nearly double the rate!
3. Sanctioned Load (kW / HP): Check your sanctioned load. If it says 6 kW or 8 kW but you only have a standard 2-BHK home, you are paying unnecessary fixed charges every month.
4. Multiplying Factor (MF): For domestic meters, the Multiplying Factor must be 1.0. If it shows 10 or 100, the bill will multiply your units 10x!

How to Dispute a Wrong Electricity Bill with Your DISCOM

If your bill contains a meter error or wrong calculation:

Take a clear, geotagged photograph of your digital meter screen showing the current kWh reading and date.
Log onto your DISCOM's consumer portal or mobile app and register an official complaint under "Billing Dispute / Wrong Reading".
Quote your Consumer Number (CA Number / Account ID) and attach the meter photo. Most DISCOMs are mandated by state electricity regulators to resolve billing complaints within 7 to 15 days.

Frequently Asked Questions About Bill Audits

What should I do if my meter shows an 'Estimated' reading bill?

Submit a photo of your actual meter reading on your DISCOM portal. They will issue a revised bill based on actual units used.

Can I get a refund for excess billing paid in previous months?

Yes. Once the DISCOM verifies the error, the excess amount is credited as an adjustment on your subsequent monthly electricity bills.
