Understanding Your Electricity Bill: A Line-by-Line Breakdown
A Pakistani electricity bill packs five to eight separate charges into a few lines. Here's what each one actually means.

The five parts of a Pakistani electricity bill
- 01Reference number. Fourteen digits, top-left. This is the only thing you need to check the bill — batch, sub-division and connection, run together.
- 02Meter readings. Previous and present, with the difference billed as units. If the bill looks wrong, this is the first line to check, not the total.
- 03Units consumed. What the slab is decided on. Cross 200 in a month and the whole month re-prices on the more expensive table.
- 04Reading date and billing period. A 38-day cycle produces more units than a 28-day one at identical daily use. Check the dates before disputing the amount.
- 05Fuel Price Adjustment. A per-unit adjustment for what fuel actually cost the system, lagging a month or two. This is where a bill usually grows when consumption did not.
- 06Payable within / after due date. Two amounts, always. The higher one includes the late-payment surcharge and applies from the day after the due date.
A drawing, not a photograph of a real bill — the layout follows the standard PITC domestic bill. Your company's bill may differ in detail, but these fields appear on all of them.
Every DISCO bill in Pakistan uses the same layout, because all eleven WAPDA-descended companies bill through the same PITC system. K-Electric's differs cosmetically but carries the same components. Once you know which block is which, the bill stops being a wall of numbers.
- 1
Consumer information
Your name, address, reference number, connection date and tariff code. The tariff code matters more than people realise — it determines which rate table applies to you, and a connection recorded in the wrong category is one of the few billing errors that is genuinely worth disputing.
- 2
Meter reading and units
Previous reading, current reading, and the difference in units (kWh). If the reading is marked as estimated rather than actual, the units are a guess — check them against your own meter before paying.
- 3
Energy charges
Units multiplied by the slab rates. This is the part that scales with how much electricity you actually used.
- 4
Adjustments and surcharges
FPA, quarterly adjustments, financing cost surcharge and similar lines. These have nothing to do with your consumption this month and are the usual explanation for an unexpected increase.
- 5
Taxes and fixed charges
GST, the PTV licence fee, meter rent and any arrears. Small individually, but they add up and they apply whether you used electricity or not.
Checking the meter reading first
- 01Read left to right. Each dial gives one digit, starting from the left. The number printed under a dial tells you which place it holds.
- 02Alternate dials run backwards. The first turns clockwise, the second anticlockwise, and so on. Check the printed digits on the face rather than assuming the direction.
- 03Between two digits, take the lower one. A pointer sitting between 8 and 9 reads 8, not 9. Only write 9 once the pointer has passed it — this is where most misreadings come from.
- 04Ignore the decimal. On a digital meter the red or smaller trailing digit is tenths and is not billed. Read 04826.4 as 04826.
Compare your reading with the present reading on the bill. A mismatch is a metering matter — ask your sub-division office for a re-check rather than disputing the amount.
Before looking at any rupee figure, compare the current reading printed on the bill against the number on your meter. This is the single most useful thing you can do, because every other figure on the bill is derived from it. If the reading is wrong, everything below it is wrong.
Bills marked as estimated happen when the meter reader could not access the meter. An estimate that runs high pushes you into a higher slab, and because Pakistani slab billing is not marginal above the protected threshold, that can cost far more than the difference in units suggests. An estimate that runs low is not a gift either — the correction lands in a later month, often pushing that month into a higher slab instead.
Photograph your meter on the same date each month
A dated photo taken on roughly the billing date is the strongest evidence you can bring to a billing dispute, and it takes seconds. Sub-division offices treat a photographed reading very differently from a verbal claim.
How the slab rates are applied
Domestic electricity is billed in slabs set by NEPRA, identical across every distribution company. There are two tables: one for protected consumers and one for everyone else.
| Units | Per unit |
|---|---|
| 1–100 | Rs 10.54 |
| 101–200 | Rs 13.01 |
| Units | Per unit |
|---|---|
| 1–100 | Rs 22.44 |
| 101–200 | Rs 28.91 |
| 201–300 | Rs 33.10 |
| 301–400 | Rs 36.46 |
| 401–500 | Rs 38.95 |
| 501–600 | Rs 40.22 |
| 601–700 | Rs 41.85 |
| 701+ | Rs 47.20 |
Representative rates compiled from publicly reported NEPRA notifications. Base rates change periodically and FPA changes monthly.
Crossing 200 units moves the whole month, not just the excess
Stay at or under 200 units and you are billed on the protected table. Go over 200 in a single billing month and the entire month is recalculated on the unprotected table — not merely the units above the line. This is why a 201-unit bill can be dramatically higher than a 199-unit one, and it is the most common reason a household is shocked by a bill after a slightly hotter month.
The lines that are not about your usage
If your consumption barely moved but the bill jumped, the explanation is almost always in this block rather than in energy charges.
- FPA (Fuel Price Adjustment)
- Reviewed by NEPRA on a near-monthly basis. It reflects what fuel actually cost the generators one to two billing cycles ago, so it lags reality and can be positive or negative. It is applied per unit, which means high-consumption households feel it most.
- Quarterly Tariff Adjustment
- A periodic true-up covering capacity payments and other costs. It appears in some months and not others, which is why a bill can rise without any visible change in usage or FPA.
- Financing cost surcharge
- A per-unit charge tied to servicing the sector's circular debt. It is set by policy rather than by your DISCO.
- Arrears
- Any previously unpaid amount carried forward. Worth checking carefully — an arrear you do not recognise should be queried before it compounds through late-payment surcharges.
Taxes and fixed charges
- GST at 17%, charged on energy charges and FPA combined rather than on the final total.
- PTV licence fee of Rs 35 per month, collected through the electricity bill regardless of whether you own a television.
- Meter rent and fixed service charges, which apply even in a month where you used no electricity at all.
- Late payment surcharge if you pay after the due date — usually a percentage of the payable amount, which makes paying on the due date meaningfully cheaper than paying a few days late.
Note the two due dates printed on most bills: the payable-within amount and the higher after-due-date amount. The gap between them is the late surcharge, shown up front.
What to do about a bill that looks wrong
- 1
Check the reading against your meter
If the bill says estimated, or the current reading is higher than what your meter shows today, that is your case. Photograph the meter.
- 2
Check the tariff category
Confirm the tariff code matches your connection type. A domestic connection billed on a commercial code is a real and fixable error.
- 3
Compare against the same month last year
Seasonal comparison is more informative than month-on-month, because Pakistani consumption is heavily seasonal. A July bill should be compared with last July.
- 4
Separate usage from adjustments
Work out whether the increase sits in energy charges or in FPA and surcharges. If it is the latter, the bill is probably correct and a complaint will not change it.
- 5
File with a complaint number
Start at your DISCO helpline or sub-division office and insist on a complaint number. Escalation later depends on having it.
Detection bills
A detection bill is raised when a company believes electricity was used without being metered correctly. It can cover several months at once and is often disputed successfully — but it must be challenged formally rather than simply left unpaid, since non-payment risks disconnection while the dispute is still open.
Common questions about electricity bills
Why is my bill high when I was away all month?
Fixed charges, meter rent and the PTV fee apply regardless of consumption, so a bill is never zero. Beyond that, check whether the reading is estimated — an unattended property is exactly where estimated readings occur, and an estimate based on your earlier usage will not reflect an empty house.
Do different DISCOs charge different rates?
No. NEPRA sets domestic slab rates and they are identical across all distribution companies. What differs between companies is service quality, load management and losses — not the rate you pay per unit.
Can I get moved to the protected category?
Protected status follows consumption rather than an application: stay at or under 200 units a month and the protected table applies. Consistently low users should check that their bills reflect this, because being billed on the wrong table is worth disputing.
What is the difference between units and kWh?
Nothing — they are the same thing. One unit on a Pakistani electricity bill is one kilowatt-hour.
Why does the bill show two different amounts?
The lower figure applies if you pay by the due date; the higher one applies afterwards and includes the late payment surcharge. The difference between them is what paying late costs you.
