What's actually on your bill

A standard IESCO residential bill has roughly these line items:

  • Variable energy charge — units consumed × slab rate (the biggest line)
  • FPA (Fuel Price Adjustment) — NEPRA-set monthly variable
  • GST 17% — applied on the variable charge + FPA
  • Financing Cost / FC Surcharge — recovers debt-servicing costs
  • Neelum-Jhelum surcharge — Rs 0.10 / unit, project debt repayment
  • TV fee — Rs 35 / month (PTV licence)
  • Meter rent / Fixed charges — sanctioned-load fixed component

Frequently asked questions

How is my IESCO bill calculated?

IESCO bills combine variable energy charges (units × slab rate), Fuel Price Adjustment (FPA), GST at 17%, Financing Cost, Neelum-Jhelum surcharge, TV fee, and any meter rent or fixed charges. Each slab boundary changes the rate, so a 401-unit bill costs significantly more than a 199-unit bill.

What is the IESCO protected tariff?

Protected category is for residential consumers who use 200 units or less for 6 consecutive months. The protected rate is much lower than the unprotected rate. If you exceed 200 units in any month, you lose protected status and pay unprotected rates until you re-qualify.

Why is my IESCO FPA so high?

FPA (Fuel Price Adjustment) reflects the variable cost of generating electricity — mostly imported LNG. It is set monthly by NEPRA based on the previous month's actual fuel costs. In 2025–26, FPA has spiked above Rs 6 per unit in some months and dipped below Rs 2 in others. It's the single most volatile line on your bill.

Can I dispute a IESCO bill?

Yes. File a written complaint with your IESCO sub-divisional office. If unresolved within 14 days, escalate to NEPRA via the e-CMS portal. Keep month-by-month meter photographs — they're your strongest evidence for estimated-reading disputes.
