HESCO Bill Correction Process 2026: How to Fix a Wrong Bill
Last updated: 20 June 2026 · By Amir Hanif
To correct a wrong or overbilled HESCO bill, review the error, gather evidence (a meter photo, your CNIC, and past bills), and file a complaint at your HESCO sub-division office, on the helpline 118, or through the official complaint portal. After HESCO verifies the meter reading and billing record, it issues a corrected bill or adjusts the amount in your next cycle — usually within a few days to one billing cycle.
Opening your electricity bill to find a shocking amount is stressful — but a wrong bill is not the end of the story. Overbilling, wrong meter readings, and incorrect tariffs happen, and HESCO has a clear process to fix genuine errors. The key is knowing exactly what to do, what evidence to bring, and where to go.
This guide walks you through the complete HESCO bill correction process in plain English — how to spot the error, file your complaint the right way, and get your money back if you’ve been overcharged. We’ve based the steps on HESCO’s complaint procedures and NEPRA’s consumer protection framework.
What Is the HESCO Bill Correction Process?
The HESCO bill correction process is the official procedure for disputing and fixing an incorrect electricity bill issued by the Hyderabad Electric Supply Company. If your bill shows more units than you used, a wrong meter reading, a detection charge you don’t recognize, or an incorrect tariff, you have the right to request a correction.
In simple terms, the process has four main stages:
- Identify — confirm exactly what’s wrong on your bill.
- Document — gather evidence like a meter photo and past bills.
- Complain — file your request through an official channel.
- Resolve — HESCO verifies and issues a corrected bill.
This consumer right applies across all Pakistani distribution companies — including LESCO, IESCO, MEPCO, FESCO, GEPCO, PESCO, SEPCO, and QESCO — under the regulation of NEPRA.
Common HESCO Billing Errors
Before you complain, it helps to know what kind of error you’re dealing with. These are the most common billing problems consumers face.
| Error Type | Typical Cause |
|---|---|
| Overbilling / excess units | Estimated or wrong meter reading |
| Wrong meter reading | Meter not read; average billed instead |
| Detection bill | Alleged meter tampering or slowness |
| Incorrect tariff/slab | Wrong consumer category applied |
| Duplicate or extra charges | Repeated arrears or wrong surcharge |
| Wrong name or reference | Data-entry or account error |
| Average billing | Meter faulty or unreadable |
Identifying the exact error type makes your complaint stronger and helps HESCO resolve it faster.
Step 1: Review and Verify Your Bill
Before filing anything, confirm the bill is actually wrong. Check your bill carefully against these points:
- Units consumed — compare with the same month last year and recent months.
- Meter reading — match the “present reading” on the bill to your actual meter.
- Reading status — look for words like “average” or “estimated.”
- Tariff and slab — confirm your consumer category is correct.
- Arrears and surcharges — check for repeated or unexplained charges.
You can quickly check your HESCO bill online using your reference number to review every detail and compare it with previous months.
Step 2: Gather Your Evidence and Documents
A well-documented complaint is resolved far faster. Prepare these before you approach HESCO:
| Document | Why It Helps |
|---|---|
| Copy of the disputed bill | Shows the error being challenged |
| Photo of the meter | Proves the actual current reading |
| Previous bills (2–3 months) | Shows your normal usage pattern |
| CNIC copy | Confirms your identity as the consumer |
| Written application | States the error and requested correction |
Step 3: File Your HESCO Bill Complaint
HESCO offers several ways to lodge a billing complaint. Choose whichever is most convenient.
Option 1 — Sub-Division Office (Most Effective)
Visit your area’s HESCO sub-division or customer services office in person. Submit your written application with copies of your evidence. In-person complaints with a meter photo are usually the fastest to resolve, especially for overbilling.
Option 2 — Helpline 118
Call the universal power utility helpline 118 to register a complaint by phone. Note down the complaint number you receive — you’ll need it to follow up.
Option 3 — Online Complaint Portal
Use HESCO’s official online complaint system or the Prime Minister’s citizen portal to lodge your complaint digitally and track its status.
📌 Always Get a Complaint Number
However you file, make sure you receive and save a complaint or tracking number. This is your proof that the complaint was registered and is essential for following up. Without it, tracking your case becomes very difficult.
Step 4: Inspection and Verification
After your complaint is filed, HESCO reviews it. Depending on the error, this may involve:
- Checking the recorded meter reading against your evidence
- Sending a team to physically inspect or re-read the meter
- Reviewing your consumption history and tariff category
- Testing the meter if a fault or tampering is alleged
If your meter is found faulty, HESCO may schedule a replacement and adjust the billing based on your average correct usage.
Step 5: Receive Your Corrected Bill
If your complaint is valid, HESCO will:
- Issue a corrected (revised) bill with the right amount, or
- Adjust the overcharged amount in your next billing cycle as a credit.
Keep checking your bill after the correction to confirm the adjustment has been applied. If you overpaid, the excess is normally credited against future bills rather than refunded in cash.
What to Do About a Detection Bill
A detection bill is a charge HESCO adds when it suspects a meter has been recording less than the actual usage, often due to a fault or alleged tampering. These bills can be large and are among the most disputed.
If you receive one you believe is unfair:
- Request the detailed calculation and the basis for the charge in writing.
- Ask for a meter inspection or laboratory test to verify the meter’s accuracy.
- Provide your consumption history showing consistent, normal usage.
- If unresolved, escalate to NEPRA with all your documentation.
⚠️ Important: We Are an Independent Website
HESCO Bill Online is an independent information site and cannot correct, adjust, or dispute your official bill. Only HESCO can do that. We explain the process to help you, but all corrections must go through HESCO’s official channels or, if needed, NEPRA. For official complaints, contact HESCO via the helpline 118 or the official HESCO website.
How to Escalate to NEPRA
If HESCO fails to resolve a genuine billing error, you have the right to escalate to NEPRA (the National Electric Power Regulatory Authority), the body that regulates all electricity distribution companies in Pakistan.
To escalate effectively:
- Keep a record of your original complaint number and HESCO’s response (or lack of one).
- Submit a written complaint to NEPRA with all supporting documents.
- NEPRA can direct HESCO to correct an unjustified bill or detection charge.
This regulatory backstop is an important consumer protection — it means HESCO is accountable for fair billing.
💡 Expert Tip from the Field
The single biggest factor in a fast bill correction is timing your evidence. Photograph your meter the moment you suspect an error, before you do anything else. A dated meter photo that contradicts the “present reading” on your bill is almost impossible to argue with, and it turns a long back-and-forth into a quick fix. Consumers who walk in with this evidence consistently get corrections faster than those who complain without proof.
How to Avoid Wrong Bills in the Future
Prevention is easier than correction. These habits help you catch and avoid billing errors:
- Check your bill every month using your reference number, as soon as it posts.
- Note your own meter reading periodically to compare with the bill.
- Watch for “average” billing — repeated estimates often lead to a correction later.
- Keep digital copies of every bill to prove your usage pattern.
- Pay on time to avoid late surcharges stacking onto a disputed amount.
If you’re also dealing with a connection or ownership issue, our guides on the HESCO name change procedure and the new connection application process walk you through those separately.
