Frequently Asked Questions
What LPG cylinder sizes are available in Nigeria?
Common sizes: 3 kg (camping/small), 5 kg, 6 kg, 12.5 kg (most popular household size), 25 kg (large household/small business), and 50 kg (commercial). The 12.5 kg cylinder is the most widely used in Nigerian homes.

A family of 4 cooking 2–3 meals per day typically uses a 12.5 kg cylinder in 30–45 days. Single-person or small household use may stretch it to 60–90 days. This calculator gives you a personalised estimate.
How much does LPG cost in Nigeria?
LPG prices vary. In 2025, retail prices range from ₦800–₦1,500 per kg depending on location and supplier. A 12.5 kg refill typically costs ₦10,000–₦18,750. Prices are higher in northern states due to transportation costs.
Is cooking gas safer than kerosene?
Yes, LPG (cooking gas) is generally safer, cleaner, and more efficient than kerosene. It burns cleaner with less indoor air pollution, heats faster, and costs less per meal cooked. The main risk is gas leaks, which are preventable with proper storage and regular hose checks.
How do I know when my gas cylinder is almost empty?
Pour hot water down the side of the cylinder. The boundary between hot (empty) and cool (has gas) shows the remaining level. You can also weigh the cylinder — subtract the tare weight (stamped on cylinder) from total weight to get remaining gas.
