NSF REG4 Certification
The NSF REG4 certification scheme for the UK market allows plumbing products and materials that are in contact with drinking water to comply with the UK Water Supply (Water Fittings) regulations. We developed this certification as a streamlined way for plumbing product manufacturers and materials suppliers to conform with UK regulations and gain timely access to the UK market.
Going through the certification process also helps you advance your entire supply chain and business to a higher level.
Regulation 4 requirements apply to the following UK regulations:
- Water Supply (Water Fittings) Regulations 1999
- Water Supply (Water Fittings) (Scotland) Byelaws 2014
- Water Supply (Water Fittings) Regulations (Northern Ireland) 2009
This scheme covers mechanical products that come into contact with drinking water, including valves, backflow prevention devices, taps, mixers, shower heads, pipes and fittings, tanks, cisterns, water meters, washing machines, dishwashers, steam ovens and many others. REG4 approval also extends to non-metallic products like rubbers, coatings, cements, resins and sealants.
The certification process was very smooth compared to other options. Being able to speak directly with NSF's technical team helped clarify technical questions, which dramatically shortened the timeframe.
