A WaterMark certified product must be marked with the WaterMark and certificate number and be listed on the WaterMark Product Database. You can search the database by inputting the certificate number, model ID or supplier/manufacturer name.

The How it works section explains how to have a product certified.

The WaterMark Schedule of products lists the products that require certification. The WaterMark Schedule of excluded products lists the products that do not require certification. If you cannot locate the product on either of these lists, the product may require a risk assessment to be undertaken to determine whether or not WaterMark certification is required.

Refer to the How it works section for further information or contact a Conformity Assessment Body.

This will depend on:

  • whether the product’s status in the improved Scheme is confirmed as included or excluded or remains unconfirmed (refer FAQ 4. And FAQ 5); and
  • whether the issuing Approved Certifier has transitioned their accreditation to the improved Scheme or not; and
  • whether the existing product certification is for Level 1 or Level 2. 

Refer to the Notice of Direction 2017/3.1, Improved WaterMark Scheme Transition Arrangements, to determine how to proceed.
