If you've been shopping for tapware, showerheads, or toilets in Australia, you've probably noticed a small blue star rating on the product page or packaging. That's the WELS rating — and it's more than just a sticker. Here's what it actually means, why it matters, and how to use it when choosing tapware for your next renovation.
What Is WELS?
WELS stands for Water Efficiency Labelling and Standards — a mandatory Australian Government scheme that requires certain plumbing and household products to display a water efficiency rating. It's been in place since 2006, and applies to products including:
- Taps and mixers
- Showerheads
- Toilets
- Washing machines
- Dishwashers
The scheme exists to help consumers make informed choices about water use, and to encourage manufacturers to design more water-efficient products over time.
How the Star Rating Works
WELS ratings run on a scale from 0 to 6 stars — the more stars, the more water-efficient the product. Alongside the star rating, labels also display the actual water flow rate, usually measured in litres per minute (L/min) for taps and showerheads.
As a general guide:
- 3 stars is a common minimum standard for many modern tapware products
- 5–6 stars represents genuinely high-efficiency products, using significantly less water without necessarily compromising performance
Why It Matters
Lower water bills A higher WELS rating generally means less water used per minute of use — over a year of daily showers, hand washing, and dishwashing, this adds up to genuine savings on your water bill.
Environmental impact Water efficiency isn't just about cost — it's about reducing household water consumption more broadly, which matters given Australia's climate and periodic water restrictions in many regions.
Building compliance In many Australian states and for many renovation/new-build projects, a minimum WELS rating is required by law for products being installed — meaning it's not just a nice-to-have, but sometimes a genuine compliance requirement your plumber or building certifier will check.
Does a Higher WELS Rating Mean Weaker Water Pressure?
This is one of the most common misconceptions. Modern tapware and showerhead design has come a long way — many high-WELS-rated products use clever aerator and flow-restrictor technology to maintain a strong, satisfying flow feel while genuinely using less water. You don't need to sacrifice a good shower experience to choose a water-efficient option.
What to Look for When Choosing Tapware
- Check the WELS rating on the product listing — reputable tapware retailers display this clearly for every product
- Consider your household's needs — a family home with high daily water use benefits more from higher-rated fixtures than a low-occupancy space
- Check your local requirements — if you're doing a full renovation, ask your builder or plumber whether your council or state has specific minimum WELS requirements for the products you're installing
