Water efficiency labelling and standards (WELS) scheme

The WELS water rating label provides water efficiency information for water-using household products.

What it is

WELS is Australia's water efficiency labelling scheme that requires certain products to be registered and labelled with their water efficiency.


It is compulsory for 

  • clothes washing machines
  • dishwashers
  • showers
  • tap equipment
  • toilet (lavatory) equipment
  • urinal equipment

WELS is optional for flow controllers.

How to use it

The WELS label carries two important pieces of information to help the consumer to compare products – efficiency stars and water consumption or water flow figures.

  • The one to six star rating allows a quick assessment of the model's water efficiency - the more stars on the label the more water efficient the product
  • The water consumption or water flow figure shows the water consumption per use for whitegoods and sanitary ware) or the water flow per minute for plumbing products based on laboratory tests.

When you are shopping for appliances or plumbing fittings, choose a product that has the highest star rating you can find for a model that is within the size/capacity range that you want as well as within your price range.
