About Water Efficiency Labelling Scheme

Overview

Started in 2009, the Mandatory Water Efficiency Labelling (Mandatory WELS) is a grading system with 0/1/2/3 tick rating denoting the water efficiency level of a product.  This a follow-up scheme from the Voluntary Water Efficiency Labelling Scheme (Voluntary WELS), introduced in 2006.

Currently, Mandatory WELS (Mandatory WELS) covers taps and mixers, dual-flush low capacity flushing cisterns (LCFCs), urinal flush valves and waterless urinals (1/2/3 tick rating) and washing machines (2/3/4-tick rating). It is mandatory for suppliers and retailers to obtain the relevant water efficiency labels for their products before advertising and displaying them for sale in Singapore. All products must publicly showcase their efficiency level at all time.  With Mandatory WELS, consumers can make informed choices when making purchases.

From 1 October 2018, the Mandatory WELS will extend its product range covering dishwashers for household use.​
