LESCO Protected Consumer – How to Stay Under 200 Units

What is a protected consumer in LESCO? If your monthly electricity consumption is 200 units or less, you qualify for subsidised rates (lifeline tariff). Exceed 200 units in any month and you become non‑protected, paying much higher rates for ALL units consumed that month.

Example: 190 units → Protected → Bill ~Rs 3,115. 210 units → Non‑protected → Bill ~Rs 8,674. That’s a difference of Rs 5,559 for just 20 extra units! To save money, monitor your meter every 5 days and reduce usage if you approach 180 units by the 25th of the month.

LESCO FCA Range 2026 – Fuel Cost Adjustment

💡 How to Reduce Your LESCO Bill – 5 Proven Tips

• Stay under 200 units – Protected consumer rates save you thousands.
• Set AC to 26°C – Each degree below 26 adds 8% to your bill.
• Install LED bulbs – Replace 10 bulbs → save 30‑50 units monthly.
• Unplug standby devices – TVs, chargers, routers consume 5‑10% of your bill.
• Monitor your meter every 5 days – If you reach 160 units by the 25th, switch to fans only.

How this LESCO bill estimate is calculated

Tariff data last reviewed: 23 August 2026. Slab rates used by this page are stored in a single file (assets/tariffs.js) and applied to every calculator on this site.

1. Your monthly units are split across the NEPRA domestic slabs and each part is charged at its own rate.
2. A fixed (minimum) monthly charge is added according to your consumption band.
3. General Sales Tax at 18% is applied to the energy plus fixed charge.

The result is a base estimate. It deliberately excludes items that change every month and are printed on your own bill.

Why your actual LESCO bill can differ

• Fuel Cost Adjustment (FCA) – typically around Rs 2.8–4.2 per unit for LESCO, changing monthly. Multiply your units by the FCA on your bill and add it.
• Quarterly tariff adjustments – recovered over several months and shown as a separate line.
• Billing period length – a cycle of 33 days records more units than one of 28 days.
• Arrears and late-payment surcharge – unpaid amounts from earlier months.
• Fixed line items – meter rent, TV fee and, where applicable, income tax or municipal charges.
• Time-of-Use meters – if your bill lists peak and off-peak units separately, a single-rate slab estimate will not match it.

LESCO serves one of the densest urban loads in Pakistan, so summer air-conditioning is the single biggest reason Lahore bills jump between May and September.

What you need before using the LESCO calculator

Only one number: units consumed this month. You can find it in two ways.

• Read the Units Consumed field on your printed LESCO bill.
• Or subtract the previous meter reading from the current reading – both are printed on the same bill.

LESCO supplies electricity in Lahore, Kasur, Sheikhupura, Nankana Sahib and Okara districts. Tariff notifications and official bill copies are published by LESCO at https://www.lesco.gov.pk/ and by NEPRA at nepra.org.pk.
