A Pakistani gas meter measures consumption in cubic feet (CF) or cubic metres (M³) and shows either a 5-dial clock face or a digital display — the meter reading subtracted from last month's reading gives the units consumed that month.
Locate Your Gas Meter
Your gas meter is typically installed outside the property or in a dedicated meter box near the main gas entry point — often near the main gate, on an exterior wall, or in a common area for apartments. In older properties, it may be in a cupboard under the stairs or near the kitchen.
The meter box may be locked — if so, the utility company's meter reader has a master key. For self-reading purposes, ensure you can access the meter yourself (ask your landlord for the key if needed). Regular self-readings protect you from billing disputes — if you know what your meter shows, you can verify the figure on each bill.
Read the Dial or Digital Display
Pakistani gas meters are one of two types:
Digital display meters (modern): Show the reading directly as a number on an LCD screen. The unit's cubic metres (m³). Read all digits including leading zeros. The reading changes automatically as gas flows — you're reading the cumulative total gas consumed since the meter was installed, not the monthly amount.
Dial meters (older properties): Have 4–6 clock-face dials. Read them from left to right, noting the digit the pointer has most recently passed. When a pointer is between two digits, write down the lower number. If a pointer appears to be exactly on a digit, check the dial to its right — if that pointer hasn't yet passed zero, write the lower number for the left dial.
Take a photo of the meter reading every month — date-stamped by your phone's camera. This photo is your evidence if a billing dispute arises.
Calculate Your Monthly Gas Consumption
Subtract last month's reading from this month's reading. The result is your monthly consumption in cubic metres. Cross-check this against the "Units Consumed" figure on your gas bill — they should match.
Example: If last month's reading was 1,847 m³ and this month shows 1,924 m³, your consumption is 77 m³ this month.
Gas companies convert cubic metres to a billing unit called MMBTU (Million British Thermal Units) for tariff calculation. The conversion uses a heat content factor specific to your area's gas supply — SNGPL uses approximately 1 m³ = 0.035 MMBTU, though this varies slightly by region. Your bill shows the final MMBTU figure used for tariff calculation.
| Meter Type | How to Read It | Unit Displayed | Common In |
|---|---|---|---|
| Dial/clock meter (older) | Read 5 dials left to right, ignore red dial | Cubic feet (CF) | Pre-2005 installations |
| Digital display meter | Read 5-digit number directly | Cubic metres (M³) or CF | Most post-2005 urban connections |
| Smart prepaid meter | Shows remaining Rs. balance | Rs. credit remaining | New SNGPL pilot areas |
| Industrial flow meter | Read totaliser display | Cubic metres (M³) | Commercial connections |
Report a Meter Problem or Suspected Faulty Reading
If your meter reading doesn't change over several months despite gas usage, or if the reading jumps dramatically without explanation, report it to your gas company:
SNGPL: Call 1199 and report the meter issue. Request a physical meter inspection — SNGPL will send an engineer to test the meter's accuracy. Meter testing is free for a first request.
SSGC: Call 111-786-786 or visit a service centre to request a meter inspection. The My SSGC app also has a complaint option for meter issues.
If the meter test confirms a fault, the gas company adjusts your previous bills based on your average historical consumption — a process called "deemed consumption" calculation. This protects you from being billed for gas that wasn't actually consumed due to the faulty meter.
When Things Go Wrong
Write down your current meter reading with a date-stamped photo. If the bill's reading is higher than your actual meter, the bill was estimated or there's a reading error. Call 1199 (SNGPL) or 111-786-786 (SSGC) to report the discrepancy and request an actual meter reading.
When in doubt, always write the lower number. Then check the dial immediately to the right — if it hasn't reached zero yet, the left dial's pointer is genuinely between those two digits and the lower one is correct.
Call your gas company immediately — an error code can indicate a meter fault, low battery in the meter electronics, or a gas supply issue. Don't attempt to reset or tamper with the meter yourself.
Check for gas leaks first (distinctive sulphur smell). If no leak, examine your geysers — water heaters are often the biggest gas consumers. A continuously running pilot light or inefficient older geyser can dramatically increase consumption.
Frequently Asked Questions
Pakistani gas meters measure in cubic metres (m³). Your bill converts this to MMBTU (Million British Thermal Units) for tariff calculation, using a heat content conversion factor that varies slightly by region and gas source.
SNGPL meter readers visit each property approximately once per month as part of the billing cycle. In remote or difficult-to-access areas, readings may be every 2 months with estimated billing in between. Request a regular reading schedule from your local service centre if you receive frequent estimated bills.
An estimated reading (marked 'E' on your bill) is calculated by SNGPL or SSGC based on your historical average when the meter reader couldn't physically access your meter. Estimated bills self-correct on the next actual reading. Three consecutive estimated readings is unusual and should be reported.
SNGPL accepts consumer self-readings through their online portal and the SNGPL app in some areas. Submitted self-readings reduce the frequency of estimated billing. Check sngpl.com.pk for self-reading submission availability in your region.
The meter number is the serial number of the physical meter device installed at your property. The consumer number is your gas account identifier. Both appear on your bill — for bill checking and payment, use the consumer number; the meter number is for technical/maintenance queries.
