Free Electricity Bill Tools & Guides
Everything on this page is free and works without sign-up: calculators built on the current NEPRA tariff, plus step-by-step guides for the things electricity consumers in Pakistan actually run into.
See All ToolsWhat This Page Is For
Online Bill Checker is an information site, and this page collects all of its tools and guides in one place. Some help you deal with today’s problem — a lost bill, a confusing charge — and some help you plan ahead, like estimating next month’s bill or working out whether solar panels make financial sense for your home.
To be clear about what we don’t do: we don’t process bill payments, sell solar equipment, or handle any transactions. Every tool here is informational. Your bill amounts always come from your DISCO’s own records, and payments always go through banks, JazzCash, Easypaisa, or your DISCO directly.
Why These Tools Exist
Electricity billing in Pakistan is genuinely confusing — tariff slabs, FPA charges, protected and non-protected categories, peak hours. Each tool here takes one of those confusing pieces and turns it into a simple answer.

Pick what you need — each one opens a dedicated page with full instructions.
Duplicate Bill Guide
Paper bill lost or never delivered? This guide shows exactly how to pull up your bill online with your 14-digit reference number and print a duplicate copy that banks accept for payment.
New Electricity Connection Guide
Applying for a new meter through the ENC system? This guide walks through the application form, the documents you’ll need (CNIC, ownership proof, wiring certificate), and how to track your application status.
Appliance Consumption Calculator
Ever wondered how much of your bill is the AC alone? Enter your appliances and their daily running hours, and this calculator shows the units each one consumes per month — so you know exactly what’s driving the bill up.
Solar Panel Calculator
Thinking about going solar? Enter your monthly units and this calculator estimates the system size you’d need (3kW, 5kW, 10kW), roughly how many panels that means, and how it compares against what you pay now.
Meezan Bank Solar Financing Guide
Can’t pay for solar upfront? This guide explains Meezan Bank’s Islamic solar financing — who qualifies, what the installment structure looks like, and which documents to prepare before visiting the branch.
Electricity Bill Calculator
Enter your consumed units and get an estimated bill using the current tariff slabs — with GST, electricity duty, TV fee, and FPA included, broken down line by line just like a real bill.
IESCO Peak & Off-Peak Hours
If you have a time-of-use (ToU) meter, units used during peak hours cost significantly more. Check the current peak and off-peak timings so you can run heavy appliances — motor, iron, washing machine — in the cheaper hours.
Bill Checking FAQs
Answers to the questions we get most often — where the reference number is, why bills jump suddenly, what FPA means, how duplicate bills work, and how to pay online.

No Sign-up
Every tool works instantly on any phone or computer — no account, no login, no app to install.
Completely Free
All tools and guides are free to use. There are no paid tiers or locked features.
Plain-Language Guides
Guides are written the way you’d explain things to a neighbour — no jargon, with the confusing bill terms explained as they come up.
Frequently Asked Questions
Common questions about the tools on this page.
Are the calculator results the same as my official bill?
Close, but not identical. The calculator uses the published NEPRA tariff, taxes, and duties — but your actual bill can differ slightly because of that month’s Fuel Price Adjustment, arrears, or subsidy changes. Treat the result as a reliable planning estimate, and your DISCO’s bill as the official figure.
Can I pay my bill through this website?
No — and be cautious of any unofficial site that claims you can. This site never asks for bank details, card numbers, or OTP codes. To pay, use your bank’s app, JazzCash, Easypaisa, or visit a bank branch with your printed bill.
How does the solar calculator work out my system size?
It takes your highest monthly consumption, divides it by average daily sunshine hours in Pakistan (roughly 5 to 5.5 usable hours), and adds a margin for system losses. That produces an approximate size like 5kW or 10kW — a starting point for talking to installers, not a replacement for a proper site survey.
Do the tools store the numbers I enter?
No. Calculator inputs are processed in your browser to show the result, and reference numbers you enter for bill checks are not saved on our servers.
Do these tools work for every DISCO?
The bill and consumption calculators use the national NEPRA tariff, so they apply to all DISCOs. K-Electric’s tariff differs slightly, so treat K-Electric estimates as rougher. The peak-hours page currently covers IESCO timings; other DISCOs follow a similar but not identical schedule.
