Liquefied petroleum gas ceiling prices for dedicated LPG stations will drop to between $2.75 to $3.16 a litre from April 1.

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

Ceiling prices are adjusted according to a specified pricing formula. The formula has two elements - the LPG international price and LPG operating price. The LPG international price is the LPG international price of the preceding month.

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.
