Who are we? Our Team


Matthew Gray MWSoc [Snr] BSc ACIPHE

Managing Director 

24 years experience 


I started out as a Mechanical Engineer - Design and Installation of commercial water systems from start to completion. With the growing emphasis on commissioning building water systems I organically moved into water treatment, microbiology and legionella control.  This experience has been very beneficial to me over the years as I am able to see the bigger picture in terms the water management of buildings water systems in both theory and practice. I was involved in the intial research on the proliferation of waterborne bacteria in pressure vessels which led to the inclusion of the advice listed in the current guidance HSG 274 Part 2. I have had several papers published on my research and our intellectual property on this subject has been used at various conferences and presentations throughout the UK.
