The Islamabad Electric Supply Company (IESCO) is responsible for providing and managing electricity across Islamabad and surrounding regions. However, many users face issues such as wrong meter readings, duplicate billing, or incorrect customer information, leading to unnecessary stress and confusion.
This guide is designed to clearly explain how to file an IESCO bill correction or complaint — both online and offline — in a simple, step-by-step manner. You’ll also learn about the required documents, expected response time, and how to contact IESCO via complaint email or customer support.
Whether you’re dealing with a wrong meter reading or a billing error, this article will help you resolve it quickly through the official IESCO complaint process.
Typical Billing Errors Customers Face
Many IESCO customers experience billing issues that require correction. The most common problems include wrong or estimated meter readings, which often lead to overbilling or inaccurate charges. Sometimes, faulty or replaced meters record incorrect data, or the system mistakenly adds duplicate bills.
Other frequent issues involve incorrect consumer details, such as spelling errors in names or addresses, and late payment surcharges added even after timely payments. If you notice any of these, you should immediately begin the IESCO bill correction process to avoid further complications.
To better understand your billing pattern or verify units charged, you can use the IESCO Bill Calculator before filing a correction request.
When You Should File for Bill Correction
You should file an IESCO complaint online or visit your nearest office for correction when your bill shows an unusually high amount without an increase in usage, or if the meter reading on the bill doesn’t match your actual meter.
Also, if you’ve already paid your previous bill but it still appears as unpaid on your next statement, this is a strong reason to submit a wrong meter reading IESCO complaint. Acting early helps ensure quick resolution and prevents extra charges or disconnection notices.
