Protected vs Unprotected Slab Explained: Why 201 Units Costs So Much More Than 200
By ECheckBills.pk · Updated October 27, 2026 · Rates are NEPRA’s 2026 residential schedule
Quick answer
A protected consumer is a household that used 200 units or fewer in each of the last six months. Protected homes pay Rs 10.54 and Rs 13.01 per unit, billed slab by slab. Unprotected homes pay one higher rate on every unit. Cross 200 units even once and you can lose protected status for about six months.
Two households use almost the same electricity. One uses 200 units and pays Rs 2,355 in energy charges. The other uses 201 and pays Rs 6,653. That gap is the protected vs unprotected slab rule, and it keeps coming back to parliament because of how sharply it hits households near the line.
This guide shows how the two categories work, what one heavy month really costs, how to check whether a late meter reading cost you your status, and what the government is proposing as of October 27, 2026.

What is a protected consumer?
A protected consumer is a residential customer who used 200 units or less in every one of the previous six months. K-Electric’s notice on the 2022 tariff changes states the rule that way, and NEPRA’s 2021 determination that created the category set the same 200-unit, six-month test.
Everyone else on a normal domestic connection is unprotected. A third group sits below both: lifeline consumers, meaning single-phase homes with a sanctioned load up to 1 kW. They pay Rs 3.95 per unit for the first 50 units and Rs 7.74 for 51 to 100.
The scale matters. Energy Minister Awais Leghari said in May 2026 that protected consumers had grown from 9.5 million to 21.5 million in four years. One more detail: these slabs apply to homes under 5 kW of sanctioned load. Homes at 5 kW or above are billed on Time of Use rates instead.
2026 rates side by side
These are base energy rates per unit. Fuel adjustments, quarterly adjustments, fixed charges, duty and taxes come on top.
Rates for 1 to 300 units match HAZECO’s published tariff page. The 301 to 400 figure reflects the Rs 1.53 cut NEPRA gave that slab in February 2026. Slabs above 400 units are not covered in this article.
The base rates for the 1 to 300 unit slabs were the same before and after NEPRA’s February 2026 revision. That revision mainly reworked fixed charges and the slabs above 300 units.
Why 201 units costs so much more
The difference is not only the higher rate. It is how each category applies it.
Protected consumers get the benefit of one previous slab. Your first 100 units are charged at Rs 10.54, and only the units from 101 to 200 are charged at Rs 13.01. Lifeline consumers get no such benefit.
Unprotected consumers get no slab-by-slab pricing. The slab your total lands in sets one rate, and that rate applies to every unit. Here is what that does:
Energy charge only, calculated from the 2026 rates above. For example, 201 units × Rs 33.10 = Rs 6,653.10.
So one extra unit, from 200 to 201, adds Rs 4,298.10 to the energy charge for a household that was protected. The same cliff exists at every unprotected slab boundary: 100 units cost Rs 2,244, while 101 units cost Rs 2,919.91.
The six-month rule and what it costs
Once a protected household records more than 200 units, the system moves it to unprotected rates. To return, it needs six straight months at 200 units or fewer. Reports differ on the count: some describe the crossing month plus five more, others describe the following six months. Check the category printed on each bill.
Here is what that means for a family that normally uses 150 units:
The month it uses 201 units: Rs 6,653.10 instead of Rs 2,355.00, a difference of Rs 4,298.10.
Each of the next five months at 150 units: Rs 4,336.50 instead of Rs 1,704.50, a difference of Rs 2,632.00.
Five months add up to Rs 13,160. The whole episode costs about Rs 17,458 in energy charges alone.
That is our arithmetic from the 2026 rates, and the real bill is higher once fixed charges, fuel adjustments and taxes are added.
Fixed charges changed in February 2026. Protected consumers now pay Rs 200 up to 100 units and Rs 300 up to 200 units, while unprotected consumers pay Rs 275 up to 100 units, Rs 300 up to 200 and Rs 350 up to 300. One report reads these amounts as per kilowatt of sanctioned load, so check how your own bill applies them.
When a late meter reading puts you over 200
This is the part most guides skip. Billing cycles are not always 30 days, and a longer cycle packs more days of use into one bill.
In a letter reported in November 2024, NEPRA told distribution companies to scale units on irregular cycles back to a 30-day month. For protected consumers, its example was 208 units over 33 days. That counts as 189 units, the consumer stays protected, and the extra units move to the next bill. Pakistan Era reports the same principle sits in NEPRA’s Consumer Service Manual, revised in 2025.
To check your own bill:
Find the previous and current reading dates and count the days between them.
Multiply your units by 30, then divide by the number of days. For 208 units over 33 days, that gives about 189.
If the result is 200 or less but your bill shows you as unprotected, ask your DISCO subdivision office to correct it.
If the company does not fix it, take the complaint to NEPRA.
You can pull up your bill here with your reference number and see both reading dates in seconds.
How to stay protected
The goal is simple: no month above 200. These habits help.
Watch the daily pace. Over a 30-day cycle, 200 units works out to about 6.6 units a day. Subtract the previous reading on your last bill from what your meter shows today to see where you stand.
Check all six months. Protection depends on the whole run, not just this month. Look at your bill history before you assume you qualify.
Test your usage before the bill arrives. The electricity bill calculator shows what a given unit count will cost.
Separate units from rupees. Fuel adjustments move your bill even when your meter does not. The FPA tracker shows the current figure, and our guide to how an electricity bill is calculated covers every line item.
QR registration and fake codes
Under the federal Cross-Subsidy Program 2026, eligible households are asked to register through the QR code printed on their bill. You enter your 14-digit reference number and CNIC, then confirm with an OTP. Make sure the name on the bill matches your CNIC, or the process can stall.
The numbers show why utilities are pushing it. By May 31, 2026, more than 2 million single-phase consumers had registered. In July, FESCO said about 1.71 million of its roughly 3.95 million protected consumers had finished, and it described registration as the way to keep the subsidy uninterrupted.
Be careful with QR codes. The Power Division has warned about fake QR codes on electricity bills that steal data. Scan only the code printed on your own official bill, and do not follow registration links forwarded in messages.
What may change
Nothing below is in force as of October 27, 2026. A tariff change needs a NEPRA determination and a government notification, and none has been issued for these ideas.
Ending the six-month penalty. On October 27, Power Minister Awais Leghari said the government is working on a proposal to remove the extra six months of charges after crossing 200 units, and is also considering raising the threshold to 250. He said relief should reach households below the poverty line rather than everyone under 200 units, citing homes with solar panels.
The September proposal. Reports on September 21 described a version where the higher rate would apply only in the month you cross 200. Pakistan Era noted it reportedly still needed IMF agreement and had no notification.
A BISP-based subsidy. Pakistan has committed to the IMF to replace the slab subsidy with targeted support through the Benazir Income Support Programme by end-January 2027. Eligibility rules and new rates have not been published.
Plan around today’s rule. If a notification arrives, the tariff page is where we will keep the current rates.
Frequently asked questions
Do I pay the higher rate only on units above 200?
▼
No. Once you cross 200 units, the month is billed as unprotected, and every unit is charged at the rate of the slab your total lands in. At 201 units that is Rs 33.10 on all 201 units, not just the last one.
How long do I stay unprotected after crossing 200 units?
▼
Under the current practice you stay unprotected for about six months, even if your usage drops. Reports differ on whether that counts the crossing month plus five more or six further months, so check the category printed on each bill.
How do I become protected again?
▼
You need six consecutive months at 200 units or fewer. Keep every month under the line, and compare your bill history to see when your six-month run completes.
Has the six-month penalty been removed?
▼
Not as of October 27, 2026. The Power Minister said the government is working on a proposal to end it and is considering a 250-unit threshold, but no notification has been issued. Until one is, the current rule applies.
Can a late meter reading push me over 200 units unfairly?
▼
It should not. NEPRA directed distribution companies to scale units on a longer billing cycle to a 30-day month. Its example: 208 units over 33 days count as 189 units, so the consumer stays protected and the extra units carry to the next bill.
Do protected consumers still pay fixed charges and taxes?
▼
Yes. Since February 2026, protected consumers pay a fixed charge of Rs 200 up to 100 units and Rs 300 up to 200 units. Fuel adjustments, quarterly adjustments, duty and taxes are added on top of the slab rates.
Do I need to register through the QR code on my bill?
▼
Eligible households are being asked to. Registration uses the QR code on your own bill, your 14-digit reference number, your CNIC and an OTP, and FESCO has said it keeps the subsidy uninterrupted. Use only the code printed on your bill, because the Power Division has warned about fake QR codes.
