We've all been there. The GEPCO meter reader drops the bill at your gate, you rip it open, and your jaw hits the floor. "How on earth did a few fans and an AC cost me this much?!" It's the ultimate Gujranwala summer experience.
The truth is, reading a Pakistani electricity bill requires a master's degree in accounting. GEPCO doesn't just charge you a flat rate for electricity. Between NEPRA's complex "slab" system, peak hours, and a mountain of government taxes, the actual cost of power is hidden in a maze of acronyms. Today, I'm going to break it down for you in plain English so you know exactly where your hard-earned Rupees are going in 2026.
1. The "Slab" System: Why Crossing 400 Units is Dangerous
Unlike buying petrol where every liter costs the same, electricity gets more expensive the more you use. NEPRA (the government authority) sets prices based on consumption "slabs".
- Protected and lifeline users: These are low-consumption categories with lower notified rates. The status depends on official eligibility rules and past usage, not just what you used this month.
- Unprotected residential users: Most normal households fall here once they do not qualify for protected status. The rate changes with the monthly unit band printed on your bill.
- The expensive zone: Once usage moves into higher bands, the per-unit rate rises and fixed charges can also appear. This is why a few extra units can make a bill feel much heavier than expected.
Current residential unprotected base rates
For a quick idea, these are the current base tariff bands used in our homepage calculator. Taxes, FCA/FPA, QTA, arrears, subsidies, and fixed charges can still change the final payable amount.
- 1-100 units: Rs. 22.44 per unit
- 101-200 units: Rs. 28.91 per unit
- 201-300 units: Rs. 33.10 per unit
- 301-400 units: Rs. 37.99 per unit plus fixed charge
- 401-500 units: Rs. 40.20 per unit plus fixed charge
- 501-600 units: Rs. 41.62 per unit plus fixed charge
- 601-700 units: Rs. 42.76 per unit plus fixed charge
- Above 700 units: Rs. 47.69 per unit plus fixed charge
How to estimate your current slab rate? Because these Rupee values change through government notifications, we built an Estimated Bill Calculator on our homepage. Enter your estimated units to get a practical approximation, then confirm final rates through official NEPRA or GEPCO notices.

2. Single-Phase vs. Three-Phase (Beware of Peak Hours)
If you have a large house with multiple ACs, you probably have a "Three-Phase" meter (sanctioned load above 5kW). If so, you need to understand Time of Use (TOU) billing.
GEPCO can charge different rates depending on the time of day for Time of Use consumers:
- Peak Hours: The current residential TOU peak base rate is Rs. 46.85 per unit. Avoid running water motors, irons, or multiple ACs during this window if you want to reduce the bill.
- Off-Peak Hours: The current residential TOU off-peak base rate is Rs. 40.53 per unit. Shift laundry, ironing, and motor usage here when possible.
If you travel often between Gujranwala, Lahore, or Islamabad and the house stays closed for a few days, TOU timing still matters when the family is home. A three-phase meter can punish careless evening usage even if the total monthly units do not look extreme.
3. The Alphabet Soup of Taxes (FPA, GST, TV Fee)
If you look at your bill, the "Cost of Electricity" is only about 70-75% of the total amount you have to pay. The rest gets swallowed by mandatory government taxes. Here is what they actually mean:
- FPA (Fuel Price Adjustment): This is the most frustrating charge. The base tariff assumes fuel (coal, gas, oil) costs a certain amount. If world fuel prices go up, NEPRA passes the extra cost to you a month or two later. If fuel gets cheaper, you sometimes get a negative FPA (a discount!), though it's rare.
- GST (General Sales Tax): A flat 18% tax slapped on top of almost everything.
- FC Surcharge (Financing Cost): A fee the government charges to pay off the massive circular debt of the power sector. Yes, you pay for the system's debt.
- Fixed Charges: These depend on tariff category, sanctioned load, and consumption band. Higher residential slabs and commercial/TOU connections can show separate fixed charges.
- PTV Fee: A small government levy that appears on many domestic bills, commonly around Rs. 35 to Rs. 36. Some categories may show a different amount or no fee.
Why Your Actual Bill May Still Differ
Even if the base unit rate is correct, your payable amount can still differ from a simple estimate. A real GEPCO bill can include monthly FCA/FPA, quarterly tariff adjustment, arrears, late payment surcharge, electricity duty, GST, and category-specific fixed charges. If your bill suddenly looks high, compare the units first, then check the adjustment and arrear lines before assuming the meter is faulty.
The Bottom Line
We can't change the taxes or the slab system, but understanding how they work is half the battle. By shifting heavy usage to off-peak hours and watching your meter before it crosses the 200, 300, or 400 unit thresholds, many households can reduce avoidable costs. If you are near the 200-unit line, also understand how protected and unprotected billing works. Once you have your final amount, you can quickly pay your GEPCO bill online using JazzCash or EasyPaisa.

Frequently Asked Questions (FAQs)
What happens if I cross exactly 400 units on my meter?
Under current NEPRA rules, crossing certain unit thresholds can change your billing tier. Depending on the notified tariff category, the higher rate may affect more than only the extra units. This is why a bill just above a slab limit can sometimes be noticeably more expensive than a bill just below it.
Why do I still have to pay FPA if I didn't use much electricity this month?
The Fuel Price Adjustment (FPA) is usually billed with a 1 to 2 month delay. The FPA amount you see on your current bill is actually the delayed fuel surcharge for the electricity you consumed a month or two ago. So, even if your current usage is low, you are paying the tax for past consumption.
Are GEPCO Peak Hours the same all year round?
No, the exact timing of peak hours can shift depending on the season and official notification. Always check the back of your physical bill or current GEPCO tariff information for the exact timing that applies to your connection.
