Adhering to BS8558 Standards

BS8558 is the British Standard for the design, installation, commissioning, and maintenance of water systems in buildings. It provides comprehensive guidelines on water sampling, system testing, and disinfection protocols.
At London Water Treatment, we follow BS8558 to the letter, ensuring:

  • Proper chlorination levels are achieved and maintained
  • Correct contact times for disinfection
  • Neutralization is conducted safely and effectively
  • Samples are taken post-chlorination for lab analysis
  • All procedures are documented in line with BS8558 requirements

Whether it's a high-rise development or a small commercial unit in Brentford, we ensure your system is fully BS8558-compliant before handover.

Chlorination Certification & Reporting

After each chlorination procedure, we provide a Certificate of Chlorination and a full report, including:

  • Project details and site specifics
  • Methodology used
  • Chlorine dosage and contact time
  • Results of microbiological testing
  • Recommendations (if any)

This documentation is often required by local authorities, water companies (like Thames Water), and health and safety inspectors before the system can be brought online.
