LESCO 2026-27 Slab Structure

Two consumer categories under NEPRA rules, based on your six-month rolling average consumption:

Protected consumer (six-month rolling average at or below 200 units):

No fixed monthly charge on protected consumers. This is the subsidised tariff for low-income households.

Non-protected consumer (six-month average above 200 units):

Plus monthly fixed charge tiered Rs 75 to Rs 550 depending on your peak slab.

TOU (Time of Use) opt-in with dual meter:

Every bill also has: FPA (Fuel Price Adjustment, variable monthly), QTR (Quarterly Tariff Adjustment), FC surcharge Rs 0.43 per unit, NJ surcharge Rs 0.10 per unit, Electricity Duty 1.5 percent of base energy charge, GST 18 percent on pre-tax total, TV fee Rs 35 fixed, and Section 235 non-filer WHT 7.5 percent on bills over Rs 25,000.

Quick Reference: Monthly Units to Approximate Total Bill

Numbers assume moderate FPA of Rs 3.50 per unit and QTR of Rs 1.50 per unit; actual bills vary Rs 500 to Rs 3,000 based on the specific FPA and QTR notified for your billing cycle. Non-filer column shows the additional 7.5 percent Section 235 WHT that stacks above Rs 25,000 monthly.

Full slab-by-slab breakdown for the most-searched consumption levels below.

LESCO Bill on 100 Units

Protected consumer (six-month average at or below 200):

• 50 units at Rs 3.95 (lifeline) = Rs 198
• 50 units at Rs 7.74 = Rs 387
• Base energy charge: Rs 585
• Fixed charge: Rs 0 (protected exemption)
• FPA at Rs 3.50 per unit: Rs 350
• QTR at Rs 1.50 per unit: Rs 150
• Minor surcharges: Rs 15
• GST 18 percent on pre-tax total: Rs 198
• TV fee: Rs 35
• Approximate total: Rs 1,300 to Rs 1,600 depending on exact FPA

At 100 units the LESCO bill is one of the cheapest household utility payments globally, thanks to the deep subsidy on the lifeline slab.

LESCO Bill on 200 Units

Protected consumer at exactly the boundary:

• 50 units at Rs 3.95 = Rs 198
• 50 units at Rs 7.74 = Rs 387
• 100 units at Rs 10.06 = Rs 1,006
• Base energy charge: Rs 1,591
• Fixed charge: Rs 0 (still protected)
• FPA approximately Rs 700
• QTR approximately Rs 300
• Minor surcharges: Rs 25
• GST 18 percent approximately Rs 470
• TV fee: Rs 35
• Approximate total: Rs 3,500 to Rs 4,200

Non-protected consumer at 200 units:

• 100 units at Rs 16.48 = Rs 1,648
• 100 units at Rs 21.32 = Rs 2,132
• Base energy charge: Rs 3,780
• Fixed charge Rs 75
• FPA approximately Rs 700
• QTR approximately Rs 300
• Minor surcharges: Rs 25
• GST 18 percent approximately Rs 875
• TV fee: Rs 35
• Approximate total: Rs 6,000 to Rs 7,000

Protected vs non-protected delta at 200 units is roughly Rs 2,500 per month. Aggressively keeping your six-month average at 200 or below is worth Rs 30,000 per year.

LESCO Bill on 300 Units

Non-protected consumer:

• 100 units at Rs 16.48 = Rs 1,648
• 100 units at Rs 21.32 = Rs 2,132
• 100 units at Rs 25.09 = Rs 2,509
• Base energy charge: Rs 6,289
• Fixed charge: Rs 200
• FPA approximately Rs 1,050
• QTR approximately Rs 450
• Minor surcharges: Rs 175
• GST 18 percent approximately Rs 1,470
• TV fee: Rs 35
• Approximate total: Rs 10,800 to Rs 11,500

This is a common Pakistani middle-class summer consumption pattern with 1-2 ACs and standard evening loads. At Rs 11,000 the household still sits comfortably below the Rs 25,000 non-filer WHT threshold.

LESCO Bill on 350 Units

Non-protected consumer:

• 100 units at Rs 16.48 = Rs 1,648
• 100 units at Rs 21.32 = Rs 2,132
• 100 units at Rs 25.09 = Rs 2,509
• 50 units at Rs 29.04 = Rs 1,452
• Base energy charge: Rs 7,741
• Fixed charge: Rs 350
• FPA approximately Rs 1,225
• QTR approximately Rs 525
• Minor surcharges: Rs 185
• GST 18 percent approximately Rs 1,850
• TV fee: Rs 35
• Approximate total: Rs 13,000 to Rs 14,500

Still below the Rs 25,000 WHT threshold for a typical filer household.

LESCO Bill on 500 Units

Non-protected consumer:

• 100 units at Rs 16.48 = Rs 1,648
• 100 units at Rs 21.32 = Rs 2,132
• 100 units at Rs 25.09 = Rs 2,509
• 100 units at Rs 29.04 = Rs 2,904
• 100 units at Rs 32.03 = Rs 3,203
• Base energy charge: Rs 12,396
• Fixed charge: Rs 350
• FPA approximately Rs 1,750
• QTR approximately Rs 750
• Minor surcharges: Rs 265
• GST 18 percent approximately Rs 2,800
• TV fee: Rs 35
• Approximate total: Rs 22,000 to Rs 24,000

At 500 units the bill sits just under the Rs 25,000 non-filer WHT trigger. In months with a heavier FPA (Rs 5 per unit or more), the same 500-unit household can slip into non-filer WHT territory. Becoming a filer eliminates this variance risk entirely.

LESCO Bill on 700 Units

Non-protected consumer:

• 100 units at Rs 16.48 = Rs 1,648
• 100 units at Rs 21.32 = Rs 2,132
• 100 units at Rs 25.09 = Rs 2,509
• 100 units at Rs 29.04 = Rs 2,904
• 100 units at Rs 32.03 = Rs 3,203
• 100 units at Rs 35.43 = Rs 3,543
• 100 units at Rs 37.65 = Rs 3,765
• Base energy charge: Rs 19,704
• Fixed charge: Rs 550
• FPA approximately Rs 2,450
• QTR approximately Rs 1,050
• Minor surcharges: Rs 375
• GST 18 percent approximately Rs 4,350
• TV fee: Rs 35
• Approximate total: Rs 28,500 to Rs 31,000

Now above the Rs 25,000 threshold. Filers stay at approximately Rs 28,500; non-filers add another Rs 2,150 to Rs 2,300 in Section 235 WHT. This is where filing your FBR return delivers a direct monthly cash saving.

LESCO Bill on 1000 Units

Non-protected consumer:

• 100 units at Rs 16.48 = Rs 1,648
• 100 units at Rs 21.32 = Rs 2,132
• 100 units at Rs 25.09 = Rs 2,509
• 100 units at Rs 29.04 = Rs 2,904
• 100 units at Rs 32.03 = Rs 3,203
• 100 units at Rs 35.43 = Rs 3,543
• 100 units at Rs 37.65 = Rs 3,765
• 300 units at Rs 42.72 = Rs 12,816
• Base energy charge: Rs 32,520
• Fixed charge: Rs 550
• FPA approximately Rs 3,500
• QTR approximately Rs 1,500
• Minor surcharges: Rs 530
• GST 18 percent approximately Rs 6,800
• TV fee: Rs 35
• Approximate total (filer): Rs 45,000 to Rs 48,000
• Approximate total (non-filer): Rs 48,000 to Rs 52,000 after Section 235 WHT

At 1000 units per month the annual LESCO spend is roughly Rs 6 lakh, which is where a 5 kW rooftop solar system with net billing pays back inside 5 to 7 years and delivers Rs 25 lakh in savings over the 25 year panel life. See our Solar Payback Calculator with your bill and system size for a personalised number.

The Slab Crossing Trick (Save Rs 500 to Rs 2,000)

LESCO progressive slabs create a knife-edge at every boundary. Consuming 201 units versus 200 is not a Rs 25 difference (one unit at the next slab rate), it is roughly a Rs 175 to Rs 350 difference because:

• Unit 201 is billed at Rs 25.09 not Rs 21.32 (a Rs 3.77 marginal rate jump)
• The monthly fixed charge tier bumps from Rs 75 to Rs 175 (a Rs 100 jump)
• GST 18 percent applies to both, adding another 18 percent to the delta

For a household within 10 units of the next boundary around the 25th of the month, cutting the AC by 2 hours daily for the last 5 days can save Rs 500 to Rs 2,000. The LESCO Bill Calculator flags a red slab-crossing warning when you are inside this window.

Filer vs Non-Filer LESCO Bill

The tariff itself is identical. The delta is the Section 235 Withholding Tax:

• Bill at or below Rs 25,000: no Section 235 WHT for anyone
• Bill above Rs 25,000: filers exempt, non-filers pay 7.5 percent

For a household consistently above 500 to 700 units monthly, the annual Section 235 WHT saving from becoming a filer is typically Rs 20,000 to Rs 50,000. Filing takes 30 minutes on iris.fbr.gov.pk with your CNIC and salary details.

Back to Protected Status (When Possible)

Once you cross 200 units in a single month, you are locked into non-protected tariff for six consecutive months regardless of subsequent consumption. Practical strategy for households at the boundary:

• Winter months (Nov to Feb): easy to stay under 200 with minimal cooling load
• Summer months (May to Sep): manage AC hours aggressively, one AC not two, run for 6 hours not 10
• Use fans as primary cooling and AC only when unbearable
• Move geyser to solar or gas water heater in winter

Cutting the six-month average back below 200 takes discipline but the tariff delta is roughly Rs 2,500 per month at 200 units, so it is Rs 30,000 per year worth of household saving.

Sources and Verification

LESCO slab rates verified against the NEPRA S.R.O. 46(I)/2026 residential tariff notification effective 13 January 2026 and the S.R.O. 279(I)/2026 mid-2026 revision. Cross-checked against LESCO's own tariff page and aggregator bill.com.pk. FPA and QTR are variable per billing cycle and must be read from your actual bill for exact accuracy, our worked examples use conservative mid-cycle values (FPA Rs 3.50 per unit, QTR Rs 1.50 per unit) that fall within typical 2026 ranges. Always confirm the current tariff on the NEPRA LESCO page before disputing a large bill. Actual LESCO bills also include occasional adjustments (previous month arrears, meter reading corrections, PTV license fee variation, cycle-specific NEPRA notifications) that our estimates cannot pre-compute. If your bill differs materially from the estimates here, the two most common causes are (a) an FPA that is significantly above or below the Rs 3.50 assumption used in our examples, or (b) you have slipped from protected to non-protected status without realising, which triggers a 60 to 90 percent bill increase at the same consumption level.
