MEPCO Detection Bill Explained – What It Is, Why You Got One & What to Do Next

You open your electricity bill one morning and see an amount that makes no sense. Three times your normal bill. Maybe five times. And somewhere in the charges, you spot the words — detection bill.

For most people in Pakistan, this is where the confusion starts. Nobody explained what it means. The MEPCO office says pay up. And you are left wondering if this charge is even legal.

This guide breaks down exactly what a MEPCO detection bill is, why it gets issued, how the amount is calculated, what the official MEPCO and NEPRA policy says about it — and most importantly, what you can do if you think it is wrong.

What Is a MEPCO Detection Bill?

A MEPCO detection bill is an additional charge issued to a consumer when MEPCO’s Meter & Testing (M&T) team or field inspection staff finds evidence of electricity theft, meter tampering, or illegal use of electricity.

It is not part of your normal monthly bill. It is a separate supplementary charge calculated based on how much electricity MEPCO estimates was used illegally — or unbilled due to a faulty or tampered meter — over a certain time period.

In simple terms: if MEPCO believes you have been using more electricity than your meter has been recording — for any reason — they issue a detection bill to recover what they say you owe.

This happens under Section 26(6) of the Electricity Act 1910 and is governed by NEPRA’s Consumer Service Manual (CSM), which outlines the rules for how detection billing must be done.

Why Does MEPCO Issue a Detection Bill?

There are several reasons a detection bill lands on your doorstep. Some are genuine. Some, unfortunately, are disputed by consumers as incorrect or unjust.

Here are the most common reasons:

1. Direct Hooking (Kunda System)

This is the most well-known form of electricity theft in Pakistan — a direct connection to the MEPCO power line without going through a meter. If MEPCO inspectors detect a kunda connection at your premises, a detection bill will be issued immediately along with a legal case.

2. Meter Tampering

If the meter shows signs of physical tampering — a drilled hole, broken seal, foreign object inside, or reversed wiring — MEPCO treats this as intentional interference. Even if you are a tenant who moved in recently, the account holder is held responsible.

3. Slow or Defective Meter

A meter running abnormally slow — whether due to tampering or a manufacturing defect — means you have been paying for fewer units than you actually used. When MEPCO detects this, they calculate the shortfall and issue a detection bill for the difference.

This is where many genuine consumers get caught out. A slow meter is not always the consumer’s fault, but MEPCO’s policy determines who pays based on whether tampering is proven.

4. Shunt or Loop in Terminal Box

An internal bypass wire in the meter terminal box can reduce or eliminate readings. This is harder to detect visually, which is why MEPCO’s M&T teams use technical checks during inspections.

5. Wrong Meter Seals or Missing Seals

If the anti-tampering seals on your meter are broken or missing, this is treated as a red flag — even if you had nothing to do with it.

MEPCO Detection Bill Policy – What the Rules Say

MEPCO’s detection bill process is governed by NEPRA’s Consumer Service Manual (CSM). Here is what the official policy covers:

On Meter Slowness: Under Clause 4.3 of the CSM-2021 (previously Clause 4.4(e) of CSM-2010), when a meter is found to be running slow, MEPCO can only charge a supplementary/detection bill for a maximum of two billing cycles — not more. NEPRA reinforced this rule in a 2024 directive specifically aimed at MEPCO after it was found that some consumers were being charged detection bills for 8 to 12 months of slowness, which violates the manual.

On Meter Tampering: If deliberate tampering is proven, MEPCO can charge the consumer for the assessed units going back further, as tampering is treated as electricity theft under the Electricity Act 1910.

On Defective Meters: If the meter was defective through no fault of the consumer, and MEPCO cannot prove tampering, the consumer should not be penalized beyond what the policy allows. Many wrongful detection bills fall in this category — where MEPCO charges for slow meter readings even when the consumer was not responsible.

How Is the MEPCO Detection Bill Calculated?

MEPCO uses a formula to estimate the unbilled units and calculate the detection charge. The general method works like this:

Step 1 – Find the Average Monthly Usage MEPCO looks at your consumption history, usually the last 6 to 12 months where the meter was believed to be working correctly, or uses a comparison with similar consumers in your area.

Step 2 – Determine the Shortfall Period They identify how many months the meter was running slow or unbilled. As per CSM policy, this should be capped at two billing cycles for meter slowness cases.

Step 3 – Calculate the Missing Units The formula looks roughly like:

Assessed Units = (Normal Average Monthly Units – Billed Units During Problem Period) × Number of Months

Step 4 – Apply the Applicable Tariff Rate The assessed units are multiplied by the relevant MEPCO tariff — residential, commercial, or industrial — for that period.

Step 5 – Add Surcharges and Taxes GST, fuel price adjustment, and other applicable charges are added to arrive at the final detection bill amount.

This is why detection bills can sometimes be shockingly high — especially if MEPCO goes back many months or applies a higher tariff slab due to the volume of estimated units.

MEPCO Detection Bill Policy on Defective Meters

This is one of the most misunderstood areas and causes the most disputes.

If your meter is defective but not tampered with — for example, it developed a manufacturing fault and started running slow — the responsibility is shared differently:

• MEPCO is responsible for meter maintenance and replacement
• The consumer should not be charged as if they were stealing electricity
• Under NEPRA’s CSM, the period of back-charging is limited
• MEPCO cannot charge you for meter slowness beyond two billing cycles

A NEPRA order from April 2025 specifically addressed MEPCO on this issue — directing the company to provide relief and credit to consumers who had been over-billed on account of slow AMR (Automatic Meter Reading) meters that were charged beyond the two-cycle limit. This is important because it sets a precedent: if you have been charged more than two months of back-units for a defective (not tampered) meter, you have grounds to dispute it.

What to Do If You Receive a MEPCO Detection Bill

Receiving a detection bill does not mean you have to accept it without question. Here is what you can do:

Step 1 – Read the Bill Carefully

Identify whether the charge is labeled as a detection bill, supplementary bill, or theft bill. Note the amount, the period being charged, and whether a meter tampering reason is given.

Step 2 – Visit Your SDO Office

Go to your local MEPCO Sub-Divisional Officer (SDO) office. Request a copy of the inspection report that led to the detection bill. You are legally entitled to see it. Ask them:

• What was the specific reason for the detection?
• What period is being charged?
• Was the meter checked in your presence?

Many genuine consumers have had detection bills reduced or cancelled at the SDO level after reviewing the original inspection report.

Step 3 – File a Written Objection

If the SDO does not resolve your issue, submit a written objection to the Divisional Superintendent (DS) or Executive Engineer (XEN). Clearly state:

• That you dispute the detection bill
• The period being charged and why it is incorrect
• Any evidence you have (e.g., regular payment history, no prior complaints)

Step 4 – Escalate to MEPCO’s Complaint Center

MEPCO has a Regional Complaint Center (RCC) at its Multan headquarters and in each circle. You can register a formal complaint there. You can also call the MEPCO helpline at 118 to register your complaint.

Step 5 – Approach NEPRA’s Consumer Complaint Cell

If MEPCO does not resolve your complaint satisfactorily, you can escalate it to NEPRA’s Consumer Complaint Cell. NEPRA handles consumer disputes against DISCOs and has the authority to direct MEPCO to revise or cancel wrongful bills. This is the same channel that resulted in the 2025 ruling mentioned above.

How to Avoid a MEPCO Detection Bill

The best way to avoid a detection bill is to make sure your meter and connection are always in order.

• Never allow anyone to tamper with your meter — not even electricians, neighbors, or even MEPCO field staff acting informally
• Report a damaged or broken meter seal immediately to your SDO in writing, so it is on record before any inspection
• Check your meter regularly — if your monthly units seem unusually low compared to your appliance usage, get it checked before MEPCO does
• Keep your payment history clean — a clean payment record helps your case if you are ever disputing a wrongful detection bill
• Report stolen electricity on your line — if a neighbor is hooking into your connection or the shared line near your premises, report it to MEPCO immediately. If losses on your feeder are attributed to theft, wrongful detection bills sometimes get distributed among consumers on that line

Can MEPCO Disconnect Your Supply Over a Detection Bill?

Yes. Under Section 24(1) of the Electricity Act 1910, MEPCO can disconnect your supply for non-payment of a detection bill — usually within seven days of issuance if you do not pay or dispute it formally.

This is why it is important to act quickly. Even if you are disputing the bill, pay what you can or request an installment plan from your SDO while the dispute is being reviewed. A partial payment or formal written objection on record can sometimes prevent disconnection during the dispute process.

Frequently Asked Questions (FAQs)

Final Word

A MEPCO detection bill is not always the end of the road. Some of them are legitimate — and if electricity has been stolen or a meter tampered, MEPCO has every right to recover those costs. But many detection bills in Pakistan are also wrongly issued, overestimated, or cover periods beyond what NEPRA policy allows.

The key is to act quickly, know your rights, and put your objection in writing. The Consumer Service Manual and NEPRA’s recent rulings are on your side when the detection bill has been issued unfairly.

And while your dispute is ongoing, the most practical thing you can do is keep an eye on all your bills online. Use the MEPCO bill check tool to monitor every month’s charges so nothing catches you off guard again.
