Learn how to refill a composite LPG cylinder safely in Pakistan — refill vs exchange, where to go, current cost per kg, and the safety checks that matter. A step-by-step guide from WAA Technologies.
Quick Answer
To refill a composite LPG cylinder in Pakistan, take it to an authorised WAA Technologies dealer or an OGRA-approved refill point — never refill it yourself at home. Staff inspect the cylinder and valve, then fill it by weight against your current gas level. Many areas also offer exchange, where you swap your empty cylinder for a filled one of the same size. In October 2026, LPG costs roughly Rs 279 per kg, so a 10 kg refill is about Rs 2,790 (the rate is set monthly by OGRA).
Key Takeaways
- ✓Refill only at an authorised WAA dealer or OGRA-approved point — never self-refill
- ✓Refill means filling your own cylinder; exchange means swapping it for a filled one
- ✓A composite cylinder is filled by weight, so you pay only for the gas added
- ✓Always check the valve, body and O-ring for damage before and after refilling
- ✓WAA composite cylinders are jointless, 100% explosion-proof, and certified to ISO 9001:2015 and BS EN 14427:2022
A composite LPG cylinder is one of the safest ways to cook with gas in Pakistan — it is lightweight, corrosion-proof, and lets you see your gas level at a glance. But like any LPG cylinder, it has to be refilled correctly. Done at the right place, a refill takes a few minutes and is completely safe. Done wrong — at an unapproved shop or, worse, at home — it is one of the most dangerous things you can do. This guide walks you through exactly how to refill a composite cylinder, where to go, what it costs, and the safety checks that protect your family.
Refill vs Exchange — Which Should You Choose?
In Pakistan you will come across two options, and people often confuse them. Refilling means your own cylinder is topped up with gas and handed back to you — you keep the same cylinder you bought. Exchange means you hand over your empty cylinder and receive an already-filled one of the same size in return, paying only for the gas.
| Factor | Refill (your cylinder) | Exchange (swap) |
|---|---|---|
| Wait time | A few minutes while filled | Instant swap |
| Your cylinder | You keep it | You give it up |
| Best for | Owners who trust their own cylinder's condition | People who want speed and no waiting |
| Cost | Pay for gas added, by weight | Pay for gas (cylinder deposit may apply) |
For a composite cylinder you bought new, refilling keeps the warranty and the cylinder you know. Exchange is convenient but make sure the swapped cylinder is a genuine, undamaged composite unit — not an old steel one.
How a Composite LPG Cylinder Is Refilled Safely (Step by Step)
- Take it to an authorised point. Bring your cylinder to a WAA dealer or OGRA-approved refill station. Do not use roadside “decanting” setups that fill from a larger cylinder — this is illegal and unsafe.
- Inspection first. Staff check the cylinder body, valve and O-ring for cracks, leaks or damage, and confirm it is within its service life.
- Weigh the empty. The cylinder is weighed so the exact tare (empty) weight is known.
- Fill by weight, not by guess. Gas is added up to the cylinder's rated capacity (e.g. 5 kg or 10 kg) — never overfilled. Filling by weight is the single most important safety rule.
- Leak test. The valve is checked with soapy water or a detector for any bubbling that signals a leak.
- Final weigh & handover. The filled weight is confirmed and the cylinder is returned to you.
The whole process is quick, and because a WAA composite cylinder is jointless and explosion-proof, it handles refilling far more safely than an old welded steel gola.
Where to Refill a Composite Cylinder in Pakistan
Refill and exchange are handled through WAA Technologies' authorised dealer network across major cities, including Lahore, Karachi and Islamabad, with more cities being added. To find your nearest point, contact WAA or check the city guide for your area. Always choose an authorised dealer over an unknown shop — it is the difference between a safe fill and a serious risk.
How Much Does an LPG Refill Cost in 2026?
LPG is priced per kilogram and the rate is revised every month by OGRA (the Oil and Gas Regulatory Authority). As of October 2026 the rate is roughly Rs 279 per kg, which puts an 11.8 kg cylinder at about Rs 3,296. On that basis:
- A 5 kg composite cylinder refill ≈ Rs 1,395
- A 10 kg composite cylinder refill ≈ Rs 2,790
These are gas-cost estimates only and change with the monthly OGRA rate and your city. For the current cylinder prices and sizes, see our composite cylinder price guide.
Mistakes to Avoid When Refilling
- Never refill at home or from another cylinder. Decanting is illegal, uncontrolled, and a leading cause of LPG fires in Pakistan.
- Never overfill. LPG needs vapour space; an overfilled cylinder can over-pressurise. Filling by weight prevents this.
- Don't ignore a damaged valve or O-ring. Replace it before refilling.
- Don't accept a swapped cylinder without checking it. Confirm it is a genuine, undamaged composite unit.
