Water rating label


About the label

The WELS water rating label is similar in appearance to the energy rating label (which clothes washing machines and dishwashers must also carry). The WELS label replaces the voluntary water conservation rating 'AAAAA' label endorsed by the Water Services Association of Austr​alia.

The WELS water rating label provides water efficiency information for water-using products. It allows consumers to compare products and rewards manufacturers and retailers who make and stock water efficient models.

The label shows:

  • A zero to six star rating that allows a quick comparative assessment of the products's water efficiency. The more stars on the label the more water efficient the product.
  • A figure showing the water consumption flow of the product based on laboratory tests.

Registration requirements

A sample of the WELS label must accompany your online application for product registration.

Label specifications are detailed in Annex B of the WELS standard (Australian and New Zealand Standard AS/NZS6400:2016 Water efficient products - Rating and labelling) This standard is available as a free download from SAI Global (link is external). Note that you will need to register with SAI Global in order to access the document.

The standard contains important information about the label design, including rounding of the water consumption figure and the sizing, colours and fonts to be used.

Please remember that different products may have different labelling requirements. It is your responsibility as the registrant to ensure that all labels meet the requirements of the WELS standard.
