For Consumers

Q1. What is the Water Efficiency labelling Scheme?
The Water Efficiency Labelling Scheme (WELS) was launched on 31 Oct 2006 as part of the 10-Litre Challenge. It is a voluntary scheme showing how efficient fittings and appliances are.

WELS enables consumers to make informed purchases based on the water efficiency of a product. It also helps to raise public awareness on water conservation and encourages more water efficient products on the market.

On 1 July 2009, the Mandatory Water Efficiency Labelling Scheme (MWELS) was introduced. It is a grading system of 0/1/2/3 ticks to reflect the water efficiency of a product.
