Meeting fast, reliable Legionella testing requirements for a growing compliance business
Diamond H2O Compliance required a laboratory partner capable of matching the pace and precision demanded by a fast-growing Legionella compliance business.
Operating in a highly regulated sector, accurate and timely laboratory data underpins every compliance decision made on behalf of clients. From the outset, Diamond H2O needed more than a transactional testing service — it required a dependable laboratory partner able to deliver consistent turnaround times, clear technical guidance, and a results system that integrated smoothly into reporting and client communication workflows.
As the business expanded across healthcare, hospitality, and care environments, a reliable and responsive laboratory relationship became critical to maintaining confidence, consistency, and regulatory compliance.
UKAS‑accredited Legionella laboratory services with rapid turnaround and technical support
Normec Latis Scientific provides Diamond H2O Compliance with responsive, high‑quality laboratory services that have scaled alongside the business as it has grown.
Fast, accurate analysis of water samples — including UKAS‑accredited Legionella culture testing — enables Diamond H2O to make informed compliance decisions without delay. The availability of multiple sample drop‑off points has further enhanced operational efficiency across a geographically dispersed client base.
Beyond testing, the Normec Latis Scientific team offers valuable technical knowledge sharing, supporting Diamond H2O’s specialists in interpreting results and advising clients with confidence. Access to the Normec Latis Scientific results management platform, Samplefy™ has streamlined data access and reporting, reducing administrative burden for a lean and growing compliance team.
Improved compliance confidence, faster reporting and scalable water testing support
The partnership with Normec Latis Scientific has strengthened Diamond H2O Compliance’s ability to deliver a fast, reliable and confident service to its customers.
Consistently accurate laboratory results and dependable turnaround times underpin compliance reporting across a growing portfolio of client sites. This supports regulatory obligations under ACoP L8 and HSG274 while reinforcing client trust in Diamond H2O’s recommendations and remediation actions.
The laboratory partnership has contributed to improved operational efficiency, reduced delays in compliance decision‑making and an enhanced level of technical advice delivered to end clients. Since its establishment in 2023, Diamond H2O Compliance has grown to support over 28 clients across more than 43 sites, with the quality and consistency of its laboratory services playing a key role in enabling this growth.
