About IESCO and its billing
Islamabad Electric Supply Company supplies electricity to Islamabad, Rawalpindi, Attock, Jhelum and Chakwal. Every month it issues bills showing your consumption in units (kWh), the payable amount within the due date, and a higher amount that applies after the due date (the late-payment surcharge).
IESCO consumers in the twin cities often have both a home and office connection — save each with its own label in your CitizenPay dashboard to check them together.
How to check your IESCO bill
- Find your 14-digit reference number — it is printed near the top of any old IESCO bill and never changes month to month. A photo of an old bill works fine.
- Open the CitizenPay bill checker and select IESCO.
- Type the number and press Check bill. Your consumer name (partially masked for privacy), billing month, units consumed, due date and payable amount appear instantly.
- Optionally, sign in and press Save & remind me to get an SMS or WhatsApp alert before every future due date.
Understanding the amounts on your bill
Payable within due date is what you owe if you pay on time. Payable after due date includes the late-payment surcharge, typically several percent extra. If arrears from previous unpaid months exist, they are included in the total — clearing them promptly avoids disconnection notices.
💡 Tip: your 14-digit reference number identifies the connection, not the person. If you've moved into a new house or shop, you can check the bill using the number on any old bill left at the property.
Need a duplicate or reprint of your IESCO bill?
If your paper bill is lost, damaged or never arrived, you do not need a duplicate copy to pay on time — the amount, due date and status above come straight from your reference number. For an official duplicate or reprint (useful for record-keeping, address-change proof or a bank application), visit your nearest IESCO customer service centre in Islamabad with your CNIC and reference number, or use IESCO's own duplicate-bill service where available. CitizenPay.pk does not issue official duplicate bills — we only display the amount, due date and status already published by IESCO.
Frequently asked questions
Is checking a IESCO bill on CitizenPay free?
Yes, completely free with no registration. You only see the bill details — we mask part of the consumer's name for privacy, exactly as official inquiry systems do.
My IESCO bill never arrived. Can I still pay on time?
Yes. Paper delivery delays don't change your due date. Check the amount online with your 14-digit reference number and pay through your bank app, wallet or any authorised collection point before the due date.
I paid but the status still shows unpaid.
Payments usually reflect within minutes, but near due dates the company's system can take up to 24 hours to update. Keep your payment receipt — it is valid proof even while the status catches up.
Can I check several IESCO connections at once?
Yes — create a free CitizenPay account and save each connection with a label like "Home" or "Shop". Your dashboard shows all of them together with individual reminders.
