The price of cooking gas has risen by 25 per cent, increasing from about ₦1,200 to ₦1,500 per kilogramme, adding to the pressure on households and businesses already facing rising energy costs.

The development comes as the price of diesel, also known as Automotive Gas Oil (AGO), climbed to as high as ₦2,300 per litre at some filling stations and depots, up from about ₦2,200 recorded in August 2026.

A mid-day depot price report for September 16, 2026, showed significant increases in diesel prices, particularly in Lagos and Port Harcourt.

In Lagos, Ibachem recorded the largest increase, with its AGO price rising from ₦1,830 to ₦2,000 per litre. Ibeto followed, moving from ₦1,835 to ₦1,970, while Duport and Integrated increased to ₦1,940 per litre.

Ardova also raised its price to ₦1,970, while Eterna and Rain Oil sold at ₦2,000 per litre. Nipco recorded ₦1,950.

Similar increases were recorded in Port Harcourt, where African Terminal, Duport and Integrated raised their diesel prices to ₦1,940 per litre.

In Warri, Matrix increased its price from ₦2,080 to ₦2,120 per litre, the highest depot price listed in the report.

The rising diesel cost could further increase operating and logistics expenses for manufacturers, transport operators, telecommunications companies and small businesses that rely heavily on diesel for electricity generation and transportation.

Meanwhile, petrol prices remained relatively stable in Lagos, ranging between ₦1,350 and ₦1,353 per litre.

Some reductions were also recorded in Calabar. Alkanes reduced its petrol price by ₦17 to ₦1,338 per litre, while Matrix cut its price by ₦10 to ₦1,355. Mainland and Soroman also reduced their prices to ₦1,338.

In Warri, Matrix and Keonamex maintained petrol at ₦1,350 per litre, while Nepal and Prudent reduced theirs to ₦1,340.

Commenting on the development, Lawal Kamaldeen, Vice-President of the Oil and Gas Service Providers Association of Nigeria (OGSPAN), described the downstream sector as unstable, with frequent price movements.

He attributed the volatility to the prolonged US-Iran war, saying prices could remain unstable in the coming weeks.
