The quota was raised to nine in January 2013.
Consumers who exhaust their quota have to buy LPG at the market price of Rs 1,258 per cylinder.
Subsidized LPG costs Rs 414 per cylinder in Delhi.
The Cabinet Committee on Political Affairs (CCPA) at its meeting on January 30 decided to raise the cap to 12. The CCPA also decided to scrap the decision to make Aadhaar cards mandatory to get subsidy on domestic LPG cylinders.
However, the decision to delink Aadhaar cards from the subsidy has not been implemented due to certain clarifications that are awaited from the cabinet, sources said.
The notification for delinking Aadhaar from LPG subsidy is likely to be issued in a few days.
