The water efficiency ratings of the water fittings and products have been awarded based on test results obtained at testing laboratories accredited by the Singapore Accreditation Council (SAC) or its Mutual Recognition Arrangement (MRA) partners. Actual water flow rates, consumption or flush volumes from these fittings and products may not be similar to the test results obtained at the laboratories at all times when put in use. Started in 2009, the Mandatory Water Efficiency Labelling Scheme (Mandatory WELS) is a grading system of 0/1/2/3 ticks to reflect the water efficiency level of a product. This is a follow-up scheme from Voluntary WELS which was introduced in 2006.

Currently, washing machines, taps and mixers, dual-flush low capacity flushing cisterns (LCFCs), urinal flush valves and waterless urinals are labelled under the Mandatory WELS. The more ticks a product has, the more water-efficient it is. With this scheme, consumers can make informed choices when making purchases. Showerheads continue to remain under the Voluntary WELS.​ With effect from 1 Apr 2017, products advertised/offered-for-sale or displayed have to bear the new water efficiency labels. Only 1/2/3-tick WELS rated taps/mixers and 2/3/4-tick WELS rated washing machines are allowed for displayed, offered-for-sale, or advertised in Singapore. ​
