What is IESCO and which areas does it supply?
IESCO (Islamabad Electric Supply Company) powers the federal capital and the twin city of Rawalpindi, along with the Potohar region districts of Attock, Jhelum and Chakwal, serving a mix of government offices, cantonments and residential areas.
IESCO powers the federal capital and Rawalpindi together with the Potohar districts of Attock, Jhelum and Chakwal. The consumer mix is distinctive: a very high share of government offices, embassies, cantonment areas and planned residential sectors, alongside older, denser parts of Rawalpindi that predate the capital entirely.
Islamabad's planned sector layout makes much of the network comparatively young and comparatively easy to maintain, and the territory carries less heavy industry than the Punjab manufacturing belt. Supply reliability in the capital also attracts a level of political attention that few other territories receive.
IESCO reports the lowest transmission and distribution losses of any distribution company in Pakistan, and recovers more than it bills in-year as payments against older arrears come in. It is one of a handful of companies that were also meeting NEPRA's timeframe for providing new connections.
Which number you need
IESCO identifies your connection by one number only: the 14-digit reference number printed at the top of the bill. There is no shorter customer or consumer ID that will work in its place — that facility exists at LESCO alone — so the printed reference number is the one to keep.
IESCO references begin with 12, 13. Those leading digits are the billing batch, and they are what lets this site work out the company from the number alone, with no dropdown to choose from.
IESCO bills through the shared system operated by PITC, the government's IT company, which is the same platform behind most of the other distribution companies. That shared infrastructure is why one number format and one lookup reach them all.
Which districts does IESCO cover?
IESCO's service area covers Islamabad، Rawalpindi، Attock، Jhelum and Chakwal.
IESCO performance in FY 2024-25
NEPRA publishes an annual assessment of every distribution company. These are IESCO's reported figures, set against the level allowed in its tariff and the national picture.
- T&D losses(FY2024-25)
- 8.61%[1]
- Allowed in tariff(FY2024-25)
- 7.31%[1]
- Revenue recovery(FY2024-25)
- 101.00%[1]
- In-year surplus(FY2024-25)
- Rs 7 bn[1]
- Loss ranking(FY2024-25)
- 1 of 10 (lower is better)
| Measure | Reported | Target | National |
|---|---|---|---|
| T&D losses | 8.61% | 7.31% | 17.55% |
| Revenue recovery | 101.00% | 100% | 96.60% |
Recovery above 100% reflects payments received against earlier arrears on top of the year's own billing, not overcharging. Sector-wide, distribution companies lost Rs 132 billion in FY 2024-25.
IESCO has the lowest reported losses of any distribution company, helped by a compact, largely urban network across the capital and Rawalpindi. It also recovers more than it bills in-year as arrears come in.
Report a meter or billing problem
Complaints for IESCO — and every other PITC company — are filed through one shared system, CCMS. You can find your account by reference number, contact number or CNIC.
The form asks for your name, mobile in 923xxxxxxxxx format, CNIC, address and a nearby landmark, plus the nature and type of the complaint. Keep the complaint number it gives you — every later stage of escalation depends on it.
Do not pay scammers. No distribution company asks for payment over the phone, for an OTP, or for money into a personal account. A call demanding immediate payment to avoid disconnection is the most common form of this fraud. Always pay through a bank, ATM or authorised wallet.
How do I pay a IESCO bill?
A IESCO bill can be paid at a bank, an ATM, JazzCash, Easypaisa or any authorised payment counter, using the same reference number.

Common questions about IESCO bills
How do I check my IESCO bill online?
Enter the Reference Number printed on any previous IESCO bill in the box above. BillHub recognises it as IESCO's and opens the real bill from PITC's official system. No account or registration is needed.
Which areas does IESCO supply?
IESCO covers Islamabad, Rawalpindi, Attock, Jhelum, Chakwal, and is headquartered in Islamabad. Every distribution company holds an exclusive NEPRA licence for its own territory, so which one supplies you is decided by your address — there is no competing supplier to switch to.
Can I get net metering with IESCO?
Yes — IESCO processes applications, inspects the installation and fits the meter. Since February 2026 the arrangement is net billing rather than net metering, so work out payback on the current basis rather than on older figures. Adoption is high across Islamabad's planned sectors, where roof orientation is consistent and housing societies often coordinate installations, though DHA and cantonment areas have their own approval steps on top of IESCO's.
Where is the IESCO Reference Number printed?
Near the top of the paper bill, usually beside your name and address. Enter it in full, with no spaces or dashes. If you no longer have a paper bill, your local IESCO sub-division office can look it up from your address and CNIC.
How do I file a billing complaint against IESCO?
Call 118 or visit your IESCO sub-division office, and take a complaint number — every later stage will ask for it. The escalation route beyond that is set out above.
Does IESCO generate its own electricity?
No — IESCO distributes only, over its own network across Islamabad and the surrounding districts. Generation is bought centrally, and the tariff is NEPRA's rather than IESCO's.
