Water Supply (Water Fitting) Regulations safeguard public health, water supplies, and promote efficient water use in the UK. UK Water Regulation 4 ensures that all water fittings meet quality standards, crucial for maintaining safe drinking water.

The Kiwa UK Regulation 4 Product Approval Scheme (KUKreg4) is designed for manufacturers and distributors of sanitary and plumbing products needing compliance with UK Water Regulation 4. The Scheme is accredited to ISO/IEC 17065 and covers a wide range of products, including tapware, pipes, valves, appliances, catering equipment and WCs.

Whilst we can carry out the testing requirements for a range of UK regulation 4 approvals, compared to alternative schemes, KUKreg4 offers broader acceptance across Europe and provides two levels of compliance, including a higher standard with additional audits. Its comprehensive testing in accredited ISO/IEC 17025 laboratories ensures high reliability, making it a more versatile and robust certification option for manufacturers and suppliers.

Once certified, your product is listed in the online Kiwa Water Regulations Approved Products Directory. Achieving Kiwa's KUKreg4 Certification Mark ensures regulatory acceptance and informs customers of rigorous, independent evaluation.

Ensuring the safety and reliability of Thermostatic Mixing Valves (TMVs) is crucial. Certified TMVs prevent scalding by maintaining safe water temperatures, making them essential for homes, hospitals, and care facilities.

Meeting stringent standards like BS EN 1111, BS EN 1287 for TMV2, and the NHS D08 Specification for TMV3, certified TMVs guarantee compliance, durability, and peace of mind.

Our TMV certification is vital for manufacturers, installers, architects, water suppliers, healthcare facilities, and ultimately consumers. It ensures products meet safety and performance standards, enhances marketability, and ensures compliance with regulations. 

Kiwa Watertec's TMV certification process includes rigorous testing and continuous assessments in ISO/IEC 17025 accredited laboratories, ensuring your products meet the highest standards of safety, performance, and compliance.

Ensuring the safety and quality of drinking water is paramount. The BS 6920 standard rigorously tests the suitability of non-metallic materials used in contact with water to prevent contamination and ensure safety. Compliance with BS 6920 helps protect public health and maintain water supply integrity.

Manufacturers and suppliers of non-metallic materials and products must comply with UK water regulations for legal installation and market acceptance. Meeting BS 6920 requirements ensures products are safe, reliable, and fit for purpose. This compliance supports research and development, KUKreg4 and KUKmat4 approvals, alternative product approvals, and Regulation 31 DWI approval.

At Kiwa Watertec, we offer comprehensive testing services in our DAkkS accredited laboratory in Germany. Our test methods include odour and flavour, colour and turbidity, extraction of harmful substances, growth of aquatic microorganisms, and extraction of metals. We test non-metallic water fittings, coatings, lubricants, and seals, supporting various approvals.

Ensuring the safety and reliability of unvented water heaters is crucial. The Kiwa UK Unvented Water Heater Approval Scheme (KUKG3) helps manufacturers comply with UK Building Regulation G3, a legal requirement that guarantees safety and excellence. The BS EN 12897 standard ensures unvented water heaters operate safely, preventing hazards like overpressure, and enhancing product trust.

Manufacturers must adhere to UK Building Regulation G3 to legally market and install their products in the UK. Compliance is essential for meeting safety standards and gaining market acceptance. Suppliers and distributors benefit by offering products that meet these regulations, fostering customer trust and satisfaction.

Kiwa Watertec provides comprehensive testing and certification services for unvented water heaters to BS EN 12897 standards. Our KUKG3 approval scheme supports manufacturers with ISO/IEC 17065 product certification, pre-compliance/consultancy testing, all conducted within our UKAS accredited laboratories.

Ensuring the safety and compliance of potable water products is crucial for public health and regulatory adherence. Kiwa Watertec's design evaluation and pre-compliance testing services help manufacturers and suppliers meet stringent standards, preventing contamination and ensuring the reliability of water systems.

By adhering to established standards like EN 1111, EN 1287, and BS EN 12897, we safeguard the quality of drinking water and protect consumers.

Compliance with standards such as the Water Supply (Water Fittings) Regulations 1999 is essential for legal installation and market acceptance. Consultants, insurance companies, retailers, water authorities, and contractors also benefit from third-party test reports, demonstrating product reliability and compliance.
