Meeting the demands for fast, reliable Legionella testing for a growing compliance business
Diamond H2O Compliance needed a laboratory partner that could keep up with the pace and precision required by a rapidly growing Legionella compliance business.
In a highly regulated industry, accurate and timely laboratory data form the basis for every compliance decision made on behalf of clients. From the start, Diamond H2O needed more than just a transactional testing service—the company required a reliable laboratory partner that could provide consistent turnaround times, clear technical guidance, and a results management system that could be seamlessly integrated into its reporting and customer communication workflows.
As the company expanded into the healthcare, hospitality, and nursing sectors, a reliable and responsive partnership with a laboratory became crucial for maintaining trust, consistency, and regulatory compliance.
UKAS-accredited Legionella laboratory services with fast turnaround times and technical support
Normec Latis Scientific provides Diamond H2O Compliance with responsive, high-quality laboratory services that have grown alongside the company.
Thanks to fast, accurate analysis of water samples—including UKAS-accredited Legionella culture tests—Diamond H2O can make informed compliance decisions without delay. The availability of multiple sample drop-off locations has further improved operational efficiency for a geographically dispersed customer base.
In addition to testing, the Normec Latis Scientific team provides valuable technical expertise, supporting Diamond H2O’s specialists in interpreting results and advising clients with confidence. Access to Normec Latis Scientific’s results management platform, Samplefy™, has streamlined data access and reporting, thereby reducing the administrative burden on a lean and growing compliance team.
Greater confidence in compliance, faster reporting, and scalable support for water testing
The partnership with Normec Latis Scientific has strengthened Diamond H2O Compliance’s ability to provide fast, reliable, and confident service to its clients.
Consistently accurate laboratory results and reliable turnaround times form the foundation for compliance reporting for a growing number of client sites. This supports the legal obligations under ACoP L8 and HSG274 while simultaneously strengthening clients’ confidence in Diamond H2O’s recommendations and remediation measures.
The laboratory partnership has contributed to improved operational efficiency, fewer delays in compliance decision-making, and a higher level of technical advice for end clients. Since its founding in 2023, Diamond H2O Compliance has grown into an organization that supports more than 28 clients at over 43 locations, with the quality and consistency of its laboratory services playing a key role in enabling this growth.
