Burnt or Defective Sui Gas Meter Replacement Guide 2026: SNGPL & SSGC Procedure, PUM Testing, Average Surcharges & Helpline

Natural gas supplied to Pakistani homes is naturally odorless methane; gas utilities inject an odorant called Tert-Butyl Mercaptan to produce the distinctive "rotten cabbage" odor for emergency detection. If you smell gas near your meter enclosure:

• Do NOT strike a match or flick electrical switches: Even toggling a light switch or operating a doorbell can create a micro-spark that ignites trapped gas clouds.
• Turn Off Main Meter Service Cock Valve: Locate the brass gas valve on the incoming pipe directly before the meter and turn it 90 degrees perpendicular to the pipe.
• Call Emergency Helpline 1199: Dial 1199 (National Sui Gas Emergency Helpline). SNGPL and SSGC emergency vans are legally bound to reach residential gas leak sites within 30 to 45 minutes to seal hazardous leaks free of charge.

Mechanical diaphragm gas meters encounter various mechanical breakdowns:

1. Completely Jammed Diaphragm (Meter Stopped): Gas flows into your stove burners, but the numeric mechanical dials remain completely frozen. SNGPL/SSGC billing software flags this as a "Defective / PUM" meter.
2. Sluggish / Slow Counter (PUM - Passed Unregistered Gas): Wear and tear on internal leather/synthetic bellows allows a portion of gas to slip through without registering index turnover.
3. Index Counter Broken or Disconnected: The dial glass is cracked, foggy with condensation, or internal cog teeth are stripped.
4. Excessive Meter Noise / Whistling: Damaged rotary valves create loud groaning noises under pressure.

Follow this official path to get your defective gas meter replaced:

Step 1: Obtain Application for Meter Testing / Replacement

Visit your regional SNGPL/SSGC Customer Care Center or download the Consumer Service Request Form from sngpl.com.pk or ssgc.com.pk.

Step 2: Submit Required Documentation

Attach:

• Photocopy of CNIC of the registered consumer or premise occupant.
• Photocopy of paid gas bill of the most recent month.
• Close-up photograph of the current gas meter dial and serial number badge.

Step 3: Receive Diary & Tracking Number

Submit the file at the billing complaints window and obtain a signed diary receipt. The sub-division will issue a Meter Inspection Order (MIO) to regional metering technicians.

When a meter is removed for testing, SNGPL/SSGC sends the unit to an accredited Gas Meter Proving Laboratory (Bell Prover Test). Under OGRA Consumer Service Regulations:

• Tolerances: Normal accuracy is ±2%. If the meter runs between -2% and -10%, it is classified as slow; beyond -10%, it is declared PUM.
• Maximum Back-Billing Limit: SNGPL and SSGC are strictly barred from back-billing a consumer for more than three previous consecutive billing cycles for a slow or defective meter.
• Formula: Average consumption is calculated based on the gas consumed during the corresponding month of the preceding year. If you used 1.2 hm³ in December 2025, they cannot arbitrarily bill you 3.5 hm³ for December 2026.

Under OGRA statutory guidelines:

Reason for Defect	Financial Liability	Timeline for Replacement
Natural wear, aging diaphragm, internal gear failure	100% Paid by SNGPL / SSGC (Free)	15 to 25 Working Days
External gas fire / accidental vehicular impact	Consumer Pays Meter Cost (approx. Rs. 8,500 – Rs. 14,000)	7 to 15 Working Days
Suspected tampering / punctured casing / bypassed index	Referred to Gas Theft Tribunal + Detection	Subject to legal inquiry

Q1: Can I use an electric compressor / gas suction pump on a slow meter?

Absolutely NOT! Using a suction compressor is a non-bailable criminal offense under the Gas (Theft Control and Recovery) Act 2016, punishable by up to 3 years imprisonment and fines of Rs. 1,000,000. It also creates extreme vacuum hazards that suck poisonous air into gas pipes.

Q2: How do I challenge an inflated PUM detection bill on my gas bill?

File an appeal before the OGRA Dispute Resolution Cell (complaints@ogra.org.pk) within 30 days of the bill date. OGRA routinely sets aside arbitrary gas utility estimates.
