About Us
Water Treatment Experts
Sentinel Water Services Ltd
Sentinel Water Services Ltd is a UK-based water hygiene, compliance, and remedial plumbing specialist supporting duty holders responsible for the safety of hot and cold water systems. We work across commercial, residential, and industrial buildings, helping clients manage Legionella risk and meet their legal obligations with confidence.
​
Our services are delivered in line with ACOP L8, HSG274 Parts 1–3, and relevant British Standards, with a strong focus on practical, proportionate compliance. We understand that effective water safety management must work within real building environments, not just on paper.
​
Unlike assessment-only providers, Sentinel combines specialist water hygiene knowledge with hands-on plumbing expertise. This allows us to fully understand system design and condition, provide clear and actionable recommendations, and carry out remedial works where required to resolve non-compliances and reduce risk.
​
We work closely with managing agents, facilities managers, landlords, education providers, and commercial organisations. Our approach is collaborative and transparent, delivering clear reporting, prioritised actions, and long-term compliance support tailored to each site.
​
Our aim is to simplify compliance, reduce risk, and provide reliable, end-to-end water hygiene solutions that help clients maintain safe and legally compliant water systems.
Why Choose Sentinel
We understand that water compliance is not just about paperwork. It requires a clear understanding of system design, usage, and condition, alongside the ability to implement corrective action when required.
​
Our approach is practical, proportionate, and site-specific, allowing clients to meet their legal obligations without unnecessary disruption or complexity. This end-to-end capability sets Sentinel apart from assessment-only providers.
