Liquefied-petroleum gas ceiling prices at dedicated filling stations will rise by up to 35 cents a litre to range from $3.57 to $3.96 a litre from November 1.

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

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