What is WRAS Testing & Approval

Understanding WRAS Approval from Kiwa

WRAS (Water Regulations Approval Scheme) is a UK compliance mark for water fittings and products. It demonstrates that a product meets the requirements of the Water Supply (Water Fittings) Regulations 1999 and is suitable for installation in UK water systems.

WRAS approval is based on:

  • Mechanical testing to accepted Test Code Sheets
  • BS 6920 testing for non-metallic materials (where applicable)
  • Documentation review

Kiwa Watertec performs all necessary WRAS-aligned testing, helping manufacturers prepare for WRAS submission or choose an alternative route via our own KUKreg4 certification.
