Cost of Spain's ubiquitous butane gas cylinders keeps rising, but price is frozen by law

However, in the absence of this state implemented freeze the maximum price would have increased by 5 per cent, to 20.52 euros per gas bottle. Its value is reviewed bimonthly on the third Tuesday of the month, by Resolution of the Directorate General for Energy Policy and Mines.

This bimonthly price review, limited to a maximum increase of five per cent, is calculated according to the cost of the raw material (propane and butane) on international markets, as well as the cost of freight and the evolution of the euro-dollar exchange rate.

However, due to the application of Royal Decree-Law 11/2022 (in force until 31 December 2022), its price is currently frozen.

Pressurised bottles of butane gas serve as an alternative to natural gas for energy consumption, especially in towns or urban areas without a connection to the natural gas network.
