About Us
About MSS Group
MSS Group delivers integrated technical and compliance-driven solutions across water hygiene, environmental consultancy, facilities management and specialist industrial services. The four operating companies – MSS Water, MSS Environmental Services, MSS Facilities Services and MSS Group – work in close alignment, combining accredited methodologies, sector-specific expertise and hands-on delivery experience to support clients in highly regulated markets where compliance, safety and reliability are critical.
The MSS Difference
MSS Group has established a strong reputation for responsiveness, proactive client management and consistently delivering the best possible outcomes. Our approach is rooted in long-term collaboration, where we prioritise client objectives, build trust and deliver services that are both compliant and operationally effective.
Operating across both public and private sectors, MSS supports industries where accreditation, safety and regulation are non-negotiable. Our four divisions – MSS Water, MSS Environmental Services, MSS Facilities Services and MSS Waste – offer a comprehensive, integrated service model. Together, they provide a consultancy-led solution that gives clients access to a wide range of technical disciplines through a single, coordinated supplier.
Our teams are highly trained, experienced and proven in managing complex projects. We are particularly well-placed to serve sectors with demanding logistical or compliance challenges, where continuity of service and specialist knowledge are essential. For many of our clients, the barriers to switching providers are high. Retention and contract awards are based on trust, performance and our ability to consistently deliver to the highest standards in critical, often regulated environments.
