What PH Water & Air Technologies does

PH Water & Air Technologies is a UK-based specialist in water and air hygiene services, founded in 2004 and headquartered in Farnborough. The company provides water treatment equipment — including chlorine dioxide systems and UV disinfection solutions — alongside air hygiene services, targeting enterprise and public-sector clients across data centres, healthcare, leisure, and local government. Its offering combines installed hardware with a remote monitoring capability delivered through the ATI SiteBox and Cello 4S platforms, supplemented by AI-driven data analysis for compliance and performance reporting.

The business operates a hybrid services-and-equipment model: revenue is generated through project contracts (e.g., the disclosed £1.2M Phase 1 and £405K Phase 2 data centre engagement), recurring monitoring and maintenance agreements, and product sales. Customer segments span named enterprise logos (global data centre operators, hotel groups) and public-sector buyers accessed via the ESPO Framework (commencing 01/01/2025). In August 2023, PH Water & Air Technologies became part of Compliance Group, integrating into a broader UK compliance services platform that broadens its cross-sell reach and procurement credentials.

Operational credentials include references to UKAS, CSA, BSRIA and CIBSE frameworks, positioning the firm for regulated-buyer procurement. The company has 51-100 employees and has been recognised with the Neutral Carbon Zone Blue Award (2025), aligning its commercial positioning with enterprise ESG and public-sector NetZero procurement criteria. No disclosed revenue figure is available.
