Liquefied-petroleum gas ceiling prices at dedicated filling stations will rise one to two cents a litre to range from $4.52 to $4.91 a litre in February.

The Electrical & Mechanical Services Department said the adjustment reflects the movement of LPG international prices in January.

Prices are adjusted according to a specified formula with two elements - the LPG international price of the preceding month and the LPG operating price. The latter is adjusted on the first day of February every year according to movement in the Composite Consumer Price Index in the previous year.
