The Protected Slab Framework — Two Tiers That CSS Unlocks
Pakistan's domestic tariff is structured by NEPRA in progressive slabs — the cost per unit rises as monthly consumption rises. Within that structure, the lowest two slabs are formally labelled protected:
Slab 1: 1–100 Units/Month
The lifeline rate — the lowest per-unit cost in the entire domestic tariff structure, designed for the smallest residential users such as single-room households and pensioners.
Slab 2: 101–200 Units/Month
The second protected tier — still meaningfully below the unprotected rates above it. This slab covers a typical family of four without air-conditioning.
Unprotected: 201+ Units/Month
Above 200 units the consumer transitions into unprotected slabs (201–300, 301–400, 401–500, 600+) — higher energy rate, steeper FPA, and larger fixed charges.
What CSS Actually Changes
CSS does not change the slab definitions — it controls who is allowed to use the protected ones. Verified occupant registration anchors the subsidy to the household that actually lives there.
Exact PKR/unit rates change with each NEPRA determination. See the tariff hub for the latest schedule. Use the bill calculator to estimate your personal saving.
Domestic Tariff Category — Your Meter Must Be Class A-1
The meter must be on a domestic tariff. In Pakistan's NEPRA-notified tariff schedule that means tariff class A-1 (Residential). Other classes are excluded by design:
✓ Eligible Tariff Class
- A-1 — Residential / Domestic connection
- Must be clearly marked on your bill under "Tariff Code"
- Applies whether owned, rented, or inherited
✗ Excluded Tariff Classes
- A-2 / A-3 — Commercial and bulk supply
- B-1 to B-4 — Industrial (small, medium, large, special)
- D-1 / D-2 — Agricultural (tube wells, SCARP)
- E-1 to E-3 — Street lighting, colonies, mosques
- F — Railway traction
Six-Month Rolling Average — How the Consumption Threshold Works
PITC computes the average of your last six months of billed units. If that number is at or below the protected threshold (typically 200 units), Rule 2 passes. The rolling average — rather than a single-month snapshot — exists because real households have lumpy consumption: summer ACs, winter heaters, festive cooking, and months away from home all create swings that should not instantly flip subsidy status.
One Bad Month Is Fine
A 350-unit summer spike in an otherwise 80-unit household barely moves the six-month average. You stay eligible. The rolling window absorbs it.
2–3 Consecutive Heavy Months
Consecutive high-usage months push the average over 200 and remove protected status the following billing cycle. The higher rate applies until the average drops back.
Recovery Is Automatic
You never need to re-register. Once your rolling average returns to ≤200 units, the protected tariff is restored automatically in the next billing cycle.
New Meters Use Partial History
A meter with only 2 months of readings is averaged across those 2 months — which can make new connections temporarily over- or under-qualify until 6 months of history builds.
One CNIC, One Protected Meter — Nationally Enforced
The third rule is the structural innovation of CSS: one CNIC can be the verified occupant of only one live domestic connection nationally. Before CSS, a household could keep multiple meters under different family members' names — each priced at protected slabs as long as each meter's usage stayed under the line. The single-CNIC rule closes that loophole permanently.
This is also why CSS asks for the occupant CNIC, not the legal owner's CNIC. The occupant is the person who actually uses the electricity. If the household head verifies meter A under their CNIC, that same CNIC cannot verify meter B elsewhere. The spouse or another family member can verify the second meter under their own CNIC.
Tenants, Landlords & Inherited Meters — You Can Still Register
One of the most frequently asked questions: my landlord owns the meter — can I still qualify? The answer is yes. CSS specifically separates the consumer name on the meter (which stays in the landlord's name in PITC records) from the verified occupant (the tenant who actually lives there and pays the bill). The tenant enters their own CNIC and mobile number, receives the OTP, and is registered as the active occupant. The subsidy anchors to the tenant household for as long as they live there.
When the tenant moves out and a new tenant moves in, the new tenant registers under their own CNIC. The previous registration ends automatically — there is no separate deregister step needed from either party.
Inherited meters work the same way: if the registered consumer is deceased and the family hasn't transferred the meter yet, the current occupant can still register as the verified occupant immediately. To clean up the underlying records, apply for a transfer of ownership at your DISCO subdivision with the death certificate and the inheritor's CNIC.
Joint Meters & Shared Connections — Common Pitfall
Joint or shared meters are technically eligible, but they often fail Rule 2 in practice: multiple families' combined consumption tends to exceed 200 units even when each individual family would qualify on their own. Only one CNIC can be the verified occupant — usually the household head who pays the bill. Other families on the same meter are not separately protected.
Where a single building hosts several distinct households on one meter, each household is much better off applying for a separate meter through the new electricity connection (ENC) route. Each separate meter can then be CSS-registered independently under its own occupant CNIC.
Solar Net-Metered Homes — Does CSS Still Apply?
Net-metering changes how billed units appear on the bill: imports minus exports. If your net billed units stay below the protected threshold, Rule 2 still passes. However, most net-metered homes have a sanctioned load above 1 kW and the installed PV system signals a non-lifeline household — DISCOs sometimes flag these for manual review. Run the eligibility check to confirm your actual status. Read the solar net-metering guides for net-metering paperwork that may also affect your tariff category independently of CSS.
Common Disqualifications at a Glance
✓ Typically Qualifies
- Domestic A-1 meter with 6-month average ≤200 units
- Tenant with own CNIC (even if meter is in landlord's name)
- Inherited meter with current occupant verifying their own CNIC
- Solar net-metered home where net billed units stay ≤200
- New connection with ≤2 months of history under 200 units/month
✗ Typically Disqualified
- Six-month average above 200 units/month
- Commercial, industrial, agricultural, or bulk-supply tariff
- Same CNIC already verified on another live domestic connection
- Meter status Permanently Disconnected or Pending in DISCO master
- Consumer name field empty or invalid in PITC records
- Joint meter where combined consumption exceeds 200 units
Eligibility Rules — Frequently Asked Questions
What are the official protected-slab cut-offs for 2026?
The protected tariff covers two micro-slabs: 1–100 units/month and 101–200 units/month. A consumer must stay at or under the 200-unit/month rolling average for at least six consecutive months to qualify. Tariff numbers themselves are notified by NEPRA from time to time - always cross-check the latest schedule on the NEPRA tariff page before assuming a specific PKR/unit rate.
Are tenants eligible if the meter is in the landlord's name?
Yes - and the CSS occupant flow exists specifically for this case. The tenant registers their own CNIC and mobile as the occupant; the consumer name on the meter (the landlord) is retained, but the subsidy is anchored to the verified occupant household. Most DISCOs do not require a fresh meter transfer to claim the subsidy as a tenant.
What disqualifies a household from the Cross Subsidy Program?
The most common disqualifications are: (1) usage above the six-month protected average, (2) the same CNIC appearing on more than one live domestic connection nationally, (3) a non-domestic tariff (commercial, industrial, agricultural, bulk supply) on the meter, and (4) the reference being marked Permanently Disconnected or Pending in the DISCO system.
Can a shared / joint meter qualify?
Joint or shared meters technically can qualify, but only one CNIC can be the registered occupant for CSS purposes. Multiple families splitting one meter usually exceed the protected average together even if each family is individually low-usage, which is why shared-meter households often see ineligible status.
Does owning a solar net-metered system affect eligibility?
Solar net-metering changes the way your billed units appear on the bill (imports minus exports). If your net billed units stay under the protected threshold the subsidy still applies, but most net-metered homes have a sanctioned load above the 1 kW protected ceiling, which can independently disqualify them. Check the eligibility tool to confirm.
