LESCO (Lahore Electric Supply Company) serves one of the largest customer bases in Pakistan, covering Lahore, Kasur, Okara, Sheikhupura and Nankana Sahib. Because so many households in these districts use air conditioners during long summers, LESCO bills often jump sharply between May and September. Understanding how the bill is built helps you spot whether an increase comes from your own consumption, from a slab change, or from adjustments and taxes that apply to everyone.

This guide explains each part of a LESCO bill step by step. Exact per-unit rates are revised by NEPRA and the federal government from time to time, so always compare with the latest official tariff notification before relying on any figure.

How a real 199-unit bill adds up

Step 1: Check your meter readings and units

Every LESCO bill shows a previous reading, a present reading and the difference between them, which is your units consumed for the month. If the reading date is late (for example 33 or 35 days instead of about 30), you may see more units than usual, which can push you into a higher slab. Compare the present reading on your bill with the actual reading on your meter. If the bill shows more units than your meter, take a photo of the meter and contact your LESCO sub-division.

Step 2: Identify your tariff category

Most homes are billed under the residential tariff (A-1). Shops and offices are billed under commercial tariff (A-2), and there are separate tariffs for industry, agriculture and bulk supply. Within residential tariff there are two important groups:

This is why many LESCO consumers try hard to stay under 200 units in winter months.

Step 3: Calculate the cost of electricity

The cost of electricity line is your units multiplied by the slab rate(s) for your category. For lower slabs the rates are applied step by step. For higher non-protected slabs, the rate of the slab you fall into can apply to a large part of your consumption, so moving from 199 to 201 units, or from 300 to 301 units, can increase the bill by much more than the cost of a few units. Fixed charges may also apply depending on your sanctioned load and category.

Step 4: Add adjustments (FPA and QTA)

Lifeline and some protected consumers may be exempted from some adjustments according to government decisions, so check the notification that applies to your category.

Step 5: Taxes and government charges

After the electricity charges, the bill adds government levies. Common items include:

If you still see these lines on a current bill, compare it with the latest notification or ask your sub-division.

Step 6: Arrears, installments and late-payment surcharge

Unpaid amounts from earlier months appear as arrears. If you pay after the due date, a late payment surcharge (LPS) is added. Installments for old balances or deferred adjustments may also be shown separately. Always check the payable within due date and payable after due date amounts.

A simple example

Suppose a non-protected residential consumer uses 250 units. The cost of electricity is calculated using the rate for that slab, then FPA and QTA are added (or subtracted) per unit, then GST is calculated on the taxable amount. Fixed items and arrears are added at the end. The same household using 195 units for six months in a row could qualify as protected and pay noticeably less per unit.
