The Water Regulations Advisory Scheme (WRAS) certifies products and materials that comply with UK water supply regulations. This includes ensuring that materials:
Do not contaminate or affect the taste and smell of drinking water
Prevent waste, misuse, and undue consumption
Can withstand long-term use in plumbing systems
WRAS approval is widely recognised by water authorities across the UK, and is often a minimum requirement in commercial builds such as hotels, restaurants, and high-end office developments.
Kiwa is a globally recognised certification body that provides independent testing and certification for water products and materials. Kiwa's testing process is equivalent to WRAS in terms of UK water regulation compliance, and includes:
Rigorous material testing (including for toxicity and odour)
Evaluation of manufacturing processes
Long-term performance and safety
Kiwa approval is accepted by water suppliers in the UK and many international markets. It is equally valid to WRAS approval, and in some cases, it offers additional flexibility, particularly for manufacturers working across different regions.
