Receiving an electricity bill is a regular part of life, but many consumers only look at the total amount payable and the due date. An electricity bill contains much more useful information, including your meter readings, electricity consumption, billing period, tariff details, taxes, adjustments, arrears, and payment information.
Understanding these details can help you identify unusual charges, compare your electricity usage with previous months, and manage your household’s energy consumption more effectively.
In this guide, we explain the common information found on electricity bills in Pakistan in simple language. Whether your electricity provider is PESCO, LESCO, MEPCO, IESCO, FESCO, GEPCO, HESCO, QESCO, TESCO, or SEPCO, the exact layout of the bill may differ, but many of the basic billing terms and concepts are similar.
If you need to access your bill online, you can also use the relevant electricity bill service available on OnlineBill.pk.
What Information Is Shown on an Electricity Bill?
An electricity bill usually contains several important details about your electricity connection and monthly consumption.
Depending on your electricity distribution company, you may see information such as:
- Consumer name
- Reference Number
- Consumer Number or Account Number
- Meter Number
- Billing Month
- Bill Issue Date
- Due Date
- Previous Meter Reading
- Current Meter Reading
- Units Consumed
- Electricity Charges
- Government taxes and duties
- Arrears or previous balance
- Adjustments
- Total Amount Payable
- Amount Payable After Due Date
The exact terms and arrangement can vary between electricity distribution companies. Therefore, if you are unsure about a specific charge, it is always best to verify the information with your relevant electricity provider.
What Is a Reference Number on an Electricity Bill?
A reference number is an important identification number associated with your electricity connection. It is commonly used to access your electricity bill through online billing services.
If you have an older electricity bill available, you can usually find your reference information printed on the bill. The exact location and format may vary depending on the electricity distribution company.
If you receive electricity from PESCO, you can visit the PESCO Online Bill page on OnlineBill.pk to access the available online bill-checking service.
Similarly, consumers can use the relevant services for:
- LESCO Online Bill
- MEPCO Online Bill
- IESCO Online Bill

- QESCO Online Bill

Tip: Keep a copy of your latest electricity bill. Your reference or consumer details can be useful when checking future bills or contacting your electricity distribution company.
What Are Electricity Units?
Electricity consumption is commonly measured in kilowatt-hours (kWh), which are often referred to simply as units on electricity bills.
One electricity unit generally represents one kilowatt-hour of electricity consumption.
For example, if an electrical appliance with a power rating of 1 kilowatt operates continuously for 1 hour, it consumes approximately 1 kWh, or one unit of electricity.
Your total monthly consumption depends on factors such as
- Number of appliances in your home
- Power rating of appliances
- How long appliances are used
- Air conditioner usage
- Electric heaters and geysers
- Refrigerator and freezer operation
- Fans and lighting
- Seasonal changes
The more electricity you consume, the higher your consumption-based charges may become. Your applicable tariff structure can also affect the final amount.
How to Read Your Electricity Meter Reading
Your electricity bill generally includes information about your previous and current meter readings.
The basic calculation is commonly based on the difference between these readings:
Current Reading − Previous Reading = Units Consumed
For example, if the previous reading was 12,500 and the current reading was 12,700:
12,700 − 12,500 = 200 units
This is a simplified example. Your actual bill may include additional factors, adjustments, tariff structures, and other applicable charges.
If your bill shows a significantly different consumption level from what you normally use, it may be worth checking the meter reading and contacting your electricity provider if you believe there is an error.
What Is the Billing Period?
The billing period indicates the period for which your electricity consumption has been calculated.
The billing period and number of days between meter readings can affect the amount of electricity consumed during that cycle.
If your bill is unexpectedly high, check whether:
- The billing period is longer than usual
- Your electricity consumption increased
- Your meter reading changed significantly
- Additional charges or previous balances were included
Understanding the billing period can help you compare your current bill with previous bills more accurately.
What Is the Due Date?
The due date is the date by which you are expected to pay the current bill to avoid applicable late-payment consequences.
The due date is normally displayed prominently on the bill. Consumers should check this date carefully rather than relying only on the month printed on the bill.
If you pay after the due date, your bill may show an additional amount or applicable late-payment charges. The exact rules can vary, so consumers should refer to their bill or contact their electricity provider for specific information.
What Are Arrears or a Previous Balance?
If your electricity bill contains arrears, a previous balance, or an outstanding amount, it may indicate that an amount from an earlier billing cycle remains unpaid or has been carried forward.
Before paying your current bill, check whether the total payable amount includes any previous outstanding balance.
If you believe you have already paid an amount that is still appearing as outstanding, keep your payment receipt or transaction record and contact your relevant electricity distribution company for assistance.
What Are Electricity Taxes and Other Charges?
Electricity bills can include different taxes, duties, surcharges, adjustments, or other applicable charges.
The exact charges may vary depending on the consumer category, applicable tariff, government policies, and other factors.
You may see different terms on your bill, including:
- GST or General Sales Tax
- Electricity Duty
- TV Fee, where applicable
- FPA or Fuel Price Adjustment, where applicable
- Other surcharges or adjustments
Not every consumer will necessarily see every charge on every bill.
Because electricity tariffs, taxes, and government policies can change, consumers should check the latest information from their electricity distribution company or relevant official authorities when they need to verify a specific charge.
What Is FPA on an Electricity Bill?
FPA commonly refers to Fuel Price Adjustment.
It is an adjustment associated with changes in fuel-related costs used in electricity generation. Depending on applicable policies and billing arrangements, it may appear as a separate item on an electricity bill.
The amount and application of such adjustments can change over time. Therefore, consumers should not assume that the same FPA amount will appear on every monthly bill.
If you want to understand a specific FPA amount shown on your bill, check the details printed on your bill or refer to official information from the relevant electricity authorities.
What Is the Total Amount Payable?
The Total Amount Payable is the amount you are required to pay according to the bill.
This amount may be affected by:
- Current electricity consumption
- Applicable tariff
- Taxes and duties
- Adjustments
- Previous arrears
- Other applicable charges
Always check whether the amount shown is the current bill amount or includes an outstanding previous balance.
You should also check the amount payable before and after the due date, if both amounts are shown on your bill.
Why Is My Electricity Bill Higher Than Last Month?
A higher electricity bill does not always mean that there is an error.
Some common reasons include:
1. Increased Electricity Consumption
Using air conditioners, heaters, geysers, or other high-power appliances for longer periods can significantly increase electricity consumption.
2. Seasonal Usage
Electricity consumption often changes with the weather. Summer cooling and winter heating can increase household electricity usage.
3. Higher Number of Units
If your meter shows more units consumed than the previous billing cycle, your electricity charges may increase.
4. Additional Charges
Taxes, adjustments, arrears, or other applicable charges can affect the final payable amount.
5. Longer Billing Period
A longer billing period may result in higher overall consumption.
If your bill is unusually high and you cannot identify the reason, compare your current meter reading and consumption with previous bills. If the issue remains unclear, contact your electricity distribution company.
