35+ years of Legionella control expertise in the UK

Built entirely by Legionella experts within the UK, on a mission to modernise and streamline the industry

Our story

Andrew and Jean worked together at an industry leading health and safety consultancy in the Legionella control team and consistently identified the same frustrations and limitations: paper logbooks, complex processes which became time consuming, inefficient and at times difficult to access and share evidence for auditing purposes

While some electronic platforms were available they were all too often limited in content, user experience or auditability.

We set out to build a digital Legionella control logbook and reporting suite that prioritises user experience without compromising on compliance with key guidance documents ACOP L8/HSG274 to enable teams to complete work on site, identify and resolve non‑compliances faster, and provide comprehensive and centrally accessible records for auditing at the click of a button.
