Wondering why your electricity bill is so high? In Pakistan, seven causes explain almost every sudden bill jump, and you can identify yours in about ten minutes. From most to least common: your summer units genuinely went up (an AC running 8 hours a day adds 240–480 units a month); you crossed the 200-unit protected limit, which reprices your entire bill — 210 units costs about Rs 6,951 in energy charges where 190 units cost Rs 2,225; a fixed charge now sits on every bill, billed per kilowatt of your sanctioned load rather than per unit, and it only appeared in February 2026; the FPA and QTR adjustment lines changed this month; the meter reader posted a wrong or estimated reading; your meter itself is running fast; or the DISCO has added a detection bill. This guide walks you through each cause in order, with the exact checks and the complaint process that fixes it.
If you typed “bill double aya” or “electricity bill zyada kyun” into Google at midnight while holding this month’s bill — yes, you’re in the right place, and no, you’re not imagining it. Work down the page in order. The checks are sequenced from most likely to least likely.
Why is my electricity bill so high? Start with units, not rupees
Before blaming anyone, look at one number: units consumed this month versus the same month last year. Every DISCO bill prints a 12-month billing history box showing units and amounts. If you’ve thrown out old bills, you can pull your recent bills free using your reference number — see check any DISCO bill online.
Then use this table to jump to the right section.
| What you see | Most likely cause | Go to |
|---|---|---|
| Units up vs last month, roughly matching last summer | Seasonal AC load — bill is real | Cause 1 |
| Units slightly up (crossed 200), bill doubled or worse | Slab crossing / lost protected status | Cause 2 |
| Units similar to last year, but every bill since March 2026 runs a few hundred rupees higher | New per-kW “Fixed Charges” line | Cause 3 |
| Units same as last month, bill up by hundreds or a few thousand | FPA / QTR adjustment lines changed | Cause 4 |
| Units way up but your usage did not change | Wrong or estimated reading | Cause 5 |
| Units creeping up month after month, no new appliances | Fast or defective meter | Cause 6 |
| Separate arrears or “detection” amount added | Detection bill | Cause 7 |
Cause 1: It is summer, and the AC really did use that much
August is the cruellest billing month. A bill printed in early August usually covers July consumption — the hottest, most humid stretch of the year, when ACs run longest and refrigerators work hardest.
Rough arithmetic for a 1.5-ton AC in Pakistani summer conditions:
- Inverter model: roughly 1 to 1.2 units per hour once the room is cool. At 8 hours a day, that is roughly 240–290 units a month, from one appliance.
- Non-inverter model: roughly 1.7 to 2 units per hour, so 8 hours a day adds 400–480 units a month.
Here is an illustrative year for a small family home (fridge, fans, lights, washing machine, one 1.5-ton inverter AC). Your pattern will differ, but the shape won’t:
| Month | AC use | Typical units |
|---|---|---|
| Dec – Feb | None | 150 – 190 |
| Mar | Occasional | ~200 |
| Apr | 2–3 hrs/day | ~260 |
| May | 5–6 hrs/day | ~340 |
| Jun | 7–8 hrs/day | ~430 |
| Jul | 8+ hrs/day | ~470 |
| Aug | 8+ hrs/day | ~460 |
| Sep | 5–6 hrs/day | ~360 |
| Oct | 1–2 hrs/day | ~250 |
| Nov | None | ~190 |
Three things make summer units extra expensive. First, higher consumption pushes you into higher slabs (next section). Second, since February 2026 the slab you land in also sets the rate of your monthly fixed charge, so a heavy month raises a line that is not even measured in units (Cause 3). Third, if you are on a time-of-use (TOU) meter, evening AC hours land in the peak window at a much higher rate — see electricity peak hours in Pakistan for the current timings.
The check: if this month’s units are within 10–15% of the same month last year, the bill is almost certainly genuine. The fix is consumption, not complaints — practical ways to reduce your bill covers what actually works.
Cause 2: You crossed 200 units and lost protected status
This is the single most brutal mechanism in Pakistani electricity billing, and it produces most of the “bill double aya” searches every summer.
Domestic consumers who keep consumption at or under 200 units per month for six consecutive months are billed as protected consumers at heavily subsidised rates. Cross 200 units in even one month and that month is billed at unprotected rates, and the six-month clock restarts. The full mechanics are in our guide to protected vs unprotected consumers.
The consumer-end base rates below are current as of August 2026. They come from the schedule notified under SRO 279(I)/2026, effective 12 February 2026, which trimmed the rates for slabs above 300 units by roughly Rs 1.5 per unit and — for the first time — added a per-kilowatt fixed charge to every bill (Cause 3). The 1–300 unit rates were left unchanged. You can verify the live schedule on the official IESCO and FESCO tariff pages. Two caveats worth noting: a NEPRA review petition against the new fixed charges, filed in March 2026, was still pending as of early August, and a further government tariff package was under discussion in late July 2026, so these numbers may move again.
| Slab | Protected (Rs/unit) | Unprotected (Rs/unit) |
|---|---|---|
| 1 – 100 units | 10.54 | 22.44 |
| 101 – 200 units | 13.01 | 28.91 |
| 201 – 300 units | — | 33.10 |
| 301 – 400 units | — | 36.46 |
| 401 – 500 units | — | 38.95 |
| 501 – 600 units | — | 40.22 |
| 601 – 700 units | — | 41.85 |
| Above 700 units | — | 47.20 |
One rule makes the cliff even steeper: FESCO’s official tariff page states that “only protected residential consumers will be given the benefit of one previous slab.” In plain words: a protected consumer using 190 units pays the first 100 units at the cheaper slab. An unprotected consumer using 210 units gets no such courtesy — all 210 units are billed at the 201–300 slab rate.
Worked example: 190 units vs 210 units
Same house, same DISCO, twenty units apart:
| 190 units (protected) | 210 units (unprotected) | |
|---|---|---|
| Calculation | 100 × Rs 10.54 + 90 × Rs 13.01 | 210 × Rs 33.10 |
| Energy charge | Rs 1,054.00 + Rs 1,170.90 = Rs 2,224.90 | Rs 6,951.00 |
| Difference | Rs 4,726 more — about Rs 236 for each of those 20 extra units | |
And that is before taxes. Add 18% GST and the gap grows past Rs 5,500; electricity duty sits on top of that. With GST included, the effective cost in the 201–300 band works out to roughly Rs 39 per unit, which is why August headlines quote “Rs 39” for anyone above 200 units. The full stack of surcharges is explained in taxes on your electricity bill.
The check: find “units consumed” on the bill. If it reads 201–230 and last month read under 200, this is your answer. If you are hovering near the limit every month, twenty units is the difference between a Rs 3,000 bill and a Rs 8,000 bill — worth planning for deliberately. Current slab-by-slab pricing across DISCOs is tracked in our per-unit price guide.
Cause 3: The FPA and QTR lines changed this month
If your units are flat but the bill still climbed, look at two lines: FPA / FCA (fuel price adjustment) and QTR ADJ (quarterly tariff adjustment). These change every single month, which is why two identical-consumption bills are almost never the same amount.
Where things stand for bills issued in mid-2026:
| Billing month | FPA line | QTR line |
|---|---|---|
| June 2026 bills | + Rs 1.19/unit (April fuel cost) | − Rs 1.9857/unit |
| July 2026 bills | + Rs 0.3364/unit (May fuel cost) | − Rs 1.9857/unit |
| August 2026 bills | June fuel cost — CPPA-G sought + Rs 1.20/unit, decision pending at NEPRA | − Rs 1.9857/unit |
Sources: NEPRA approved the May FCA of Rs 0.3364 per unit for July bills through S.R.O. 1690(I)/2026, replacing the Rs 1.19 charged in June (Pakistan Observer). The negative quarterly adjustment of Rs 1.9857 per unit applies to June, July and August 2026 bills for DISCO and K-Electric consumers, worth Rs 67.17 billion in total relief (Business Recorder). For August, NEPRA heard CPPA-G’s request for a June FCA of about Rs 1.20 per unit on 29 July and reserved its decision; if approved as filed, a 300-unit household pays roughly Rs 360 extra on that line (Energy Update).
Notice what this means for August: the FPA line may swing from +Rs 0.34 to around +Rs 1.20. On 300 units, that swing alone adds about Rs 260 with zero change in your consumption. August is also the final month of the −Rs 1.99 QTR relief, so that cushion disappears from September’s bills. Lifeline and prepaid consumers are exempt from these adjustments under the current notifications; check the exemption list in each month’s SRO if you think one was applied to you wrongly.
FPA also attracts GST, so a Rs 360 FPA line actually costs you about Rs 425. How the charge is calculated, which month’s fuel it covers, and why it lags two months behind are covered in our full guide to FPA in your electricity bill.
The check: put last month’s bill and this month’s side by side and compare the FPA and QTR lines only. If those two lines explain the difference, nothing is wrong with your meter or reading. This is a system-wide adjustment applied to every consumer in the country.
Cause 4: Wrong meter reading or an estimated “average” bill
Now the causes where the DISCO, not the tariff, is the problem.
Most DISCO bills now print a photo of your meter taken on reading day, with the “present reading” beside it. Overbilling through inflated readings is not a conspiracy theory — NEPRA’s own monitoring has repeatedly pulled up DISCOs for posting readings above the meter photo or stretching billing periods beyond 30 days, and its Consumer Service Manual is the rulebook DISCOs must follow on reading, billing and correction.
Run this three-number check:
- Your meter now. Go to the meter and note the kWh figure on the display.
- The photo on the bill. Zoom into the printed snap (it is on the bill for LESCO, MEPCO, FESCO and most other DISCOs). Read the digits in the photo yourself.
- The “present reading” on the bill. This is the number you were actually billed on.
All three should line up: the photo digits should equal the present reading, and your meter today should read slightly higher (you’ve used electricity since reading day). If the present reading is higher than the photo shows, or higher than your meter reads today, you have a provable wrong-reading case — photograph your meter immediately, with the serial number visible, and file the complaint the same day (process in the “What to do” section below).
Watch for these variants:
- Estimated / average billing. If the reader never visited (locked gate, no photo on the bill), the DISCO may bill you on an “average” basis. The units are a guess. When the next real reading comes, all accumulated units land in one month — often shoving you into a higher slab or past the 200-unit limit in one artificial spike. Under the Consumer Service Manual, billing is supposed to be based on actual readings, a defective meter must be replaced immediately (or within two billing cycles where no replacement is available), and a billing period should be around 30 days — a 40-day “month” inflates your slab position all by itself. Check the “reading date” and “issue date” on recent bills.
- Slab spillover from late reading. Same effect, different cause: two late readings in a row concentrate 35–40 days of summer units into one bill.
The check: meter photo vs present reading vs your own meter. Five minutes, and it settles whether the reading is real.
Cause 5: A fast or defective meter
Rarer than people believe, but real. If your units have crept upward for months with no new appliances, no new tenants and no seasonal explanation, test the meter before paying for the DISCO’s mistake.
Home self-test (free, 30 minutes): switch off every breaker except one known load — say a 1000-watt iron — and run it for exactly 30 minutes. The meter should advance by roughly 0.5 units. If it advances by a unit or more, you have grounds for an official test. (Switch everything off first; a fridge kicking in mid-test ruins the result.)
Official meter test: apply in writing at your sub-division office for a meter accuracy check. The DISCO tests the meter (a small fee applies; in many cases it is refunded if the meter proves faulty) and, under the Consumer Service Manual, must replace a meter found defective immediately, or within two billing cycles at most. If you do not trust the DISCO’s own lab result, you can ask for a check meter to be installed in parallel, and you can escalate to NEPRA (below).
Cause 6: A detection bill appeared
A detection bill is a back-charge for units the DISCO believes you consumed but were never billed — because the meter was slow, dead, bypassed or tampered with. It usually arrives as a separate bill or a fat “arrears” line, sometimes for tens of thousands of rupees, and it is the most disputed item in Pakistani billing.
Know the rule that wins most disputes: for a slow or defective meter, the Consumer Service Manual caps detection billing at a maximum of two billing cycles, and NEPRA has explicitly rejected DISCO requests to stretch that period. One documented exception exists: where a backup or AMR check meter actually recorded the slowness, the CSM allows a supplementary bill of up to six months — but the DISCO must produce that metering record, not an estimate. So if you are handed a detection bill covering six months of “slow meter” with no check-meter data behind it, the amount beyond two cycles is not chargeable under the rules. Put that in writing in your complaint and cite the CSM. Theft and meter-tampering cases follow separate CSM provisions with their own limits and evidence requirements; if you are accused of theft you did not commit, demand the assessment basis in writing and escalate to NEPRA rather than negotiating informally.
The check: the bill or accompanying notice must state the detection period and the basis of assessment. Count the months. More than two cycles for a slowness claim, with no check-meter record to back it, means you are over-charged by rule.
What to do now: the complaint ladder that actually works
Whatever the cause, the process is the same four rungs. Keep everything in writing and keep copies.
- Sub-division office (SDO / customer services), before the due date. Take the bill, your CNIC copy, and your dated meter photo. Ask for a bill correction (wrong reading), a meter test application (fast meter), or a revised detection bill citing the two-cycle cap. For a genuinely large but correct bill, ask the SDO or Revenue Officer for installments — DISCOs routinely split an unusually heavy bill into 2–4 parts on written request, especially in summer.
- DISCO helpline and app. Dial 118 (the universal electricity complaint line routed to your DISCO) or use your DISCO’s website or mobile app to log a numbered complaint. Note the complaint number — it matters at the next rung.
- Pakistan Citizen’s Portal (PMDU). A complaint filed through the PM’s portal is tracked and time-bound, and DISCOs answer for it. Attach the meter photo and your earlier complaint number.
- NEPRA. The regulator of last resort. File online at nepra.org.pk (Consumer Affairs) if the DISCO has not resolved the matter within the CSM timelines. NEPRA can order corrections, refunds and penalties — its decisions on wrongly charged detection bills show it does use that power.
One practical warning: do not simply refuse to pay while you fight. Non-payment risks disconnection, and reconnection is its own ordeal. Get the correction or installment plan agreed before the due date — that is exactly what the SDO visit is for. Paying a disputed bill does not kill your complaint; refunds are issued as credits in later bills.
Stop next month’s shock before it happens
- Photograph your meter on the 1st of every month. A dated photo archive turns every future dispute into a two-minute win.
- Track units, not rupees. Rupees move with FPA and taxes; units only move with your consumption. A cheap energy-monitor plug or your meter’s daily readings tell you where the units go.
- Guard the 200-unit line. If you’re at 185 units on the 25th of the billing cycle, those last five days of “thora sa AC” can cost Rs 4,700. Check your reading date and ration accordingly.
- Shift load out of peak hours if you’re on a TOU meter; timings and rates are in our peak hours guide.
- Cut the baseline. Inverter AC serviced, fridge seals checked, water pump on a timer — the boring list in reduce your electricity bill is boring because it works.
- Thinking solar? The rules changed this year. Read net metering in Pakistan 2026 before buying panels on a shopkeeper’s promise.
FAQs
My units are almost the same as last month, but the bill is Rs 1,500 higher. Why?
Compare the FPA and QTR ADJ lines on both bills. These adjustment lines change monthly: June 2026 bills carried +Rs 1.19/unit FPA, July bills +Rs 0.3364, and the August FPA was still awaiting NEPRA’s decision (about Rs 1.20/unit sought), so identical units can produce noticeably different totals. GST is charged on the FPA amount too, which amplifies the swing.
My neighbour uses more units than me but pays less. How is that possible?
The likeliest reasons: they are a protected consumer (six months under 200 units) while you are unprotected, so their per-unit rate is less than half of yours; they are on a different consumer category or TOU meter; or their billing cycle dates differ, catching a different FPA month. Two houses on the same street can legitimately pay very different rates for similar consumption.
What is an “average” or estimated bill, and how do I get it corrected?
If the meter reader could not access your meter, the DISCO bills you on estimated units — no meter photo appears on the bill. The danger is the catch-up: when a real reading finally happens, the accumulated units land in one month and can push you into a higher slab. Take a photo of your actual meter reading, go to your sub-division office before the due date, and ask for the bill to be revised on actual reading. Persistent estimated billing violates the Consumer Service Manual’s requirement to bill on actual readings.
Can the DISCO charge a detection bill covering six months of a slow meter?
Generally no. NEPRA’s Consumer Service Manual caps detection bills for a slow or defective meter at two billing cycles, and NEPRA has rejected DISCO proposals to extend this and ordered refunds where the cap was violated. The narrow exception is slowness recorded by a backup or AMR check meter, which can be charged as a supplementary bill for up to six months. If your detection bill covers more than two cycles with no such metering record, dispute the excess in writing citing the CSM and escalate to NEPRA if the DISCO refuses.
The present reading on my bill is higher than what my meter actually shows. What should I do?
That is a provable over-reading. Photograph your meter today with the serial number and full display visible, then file a written complaint at your sub-division office (and log it on 118 or your DISCO’s app) before the due date, attaching the photo. The billed reading can be corrected against physical verification, and excess units are adjusted in the next bill. Your own dated photo beats the meter reader’s entry.
Is there a way to test my meter at home before applying for an official test?
Yes: a load test. Turn off every breaker except one, run a single known appliance (a 1000W iron) for exactly 30 minutes, and watch the meter: it should advance about 0.5 units. Advancing 1 unit or more suggests a fast meter. That result is not legally binding, but it tells you whether paying the official meter-test fee at your sub-division office is worth it.
Why is my August 2026 bill higher than July’s even though NEPRA announced relief?
Three August-specific factors stack up: the bill covers peak-summer July consumption, the highest of the year; the FPA line may jump from +Rs 0.3364 to around +Rs 1.20 per unit if NEPRA approves the June fuel adjustment as sought; and August is the final month of the −Rs 1.9857/unit quarterly relief, which still softens the bill but is about to disappear. Higher units also mean more rupees per line even at unchanged rates.
