At TerraBrook Solutions, we provide comprehensive Legionella risk assessments and control measures to help you meet your legal duties under HSE L8 and ACOP guidelines. Our expert technicians assess water systems across your site, identify potential areas of risk, and deliver tailored control strategies to prevent Legionella bacteria proliferation. From temperature monitoring to asset mapping and written scheme implementation, we ensure your systems are safe, compliant, and effectively managed.

• Legionella Risk Assessments
  Carried out in accordance with ACOP L8 and HSG274 for commercial, healthcare, and residential buildings.

• Legionella Sampling & Testing
  UKAS-accredited lab testing for Legionella and other waterborne pathogens.

• Temperature Monitoring & Record Keeping
  Monthly checks with digital reporting and audit trails.

Our water quality testing and analysis services ensure that your systems meet UK water safety standards. Using advanced testing methods and accredited laboratories, we analyse water samples for contaminants, chemical balance, and microbial presence. Whether you're managing a cooling tower, potable supply, or closed-loop system, we provide detailed reports and recommendations to help you maintain clean, compliant, and efficient water systems across commercial and industrial sites nationwide.

Regular tank cleaning and maintenance are essential for preventing bacterial contamination, sediment accumulation, and system inefficiency. Our team performs thorough inspections, decontamination, and disinfection of cold water storage tanks and associated pipework. We work to ensure your systems are fully operational, legally compliant, and delivering the clean, safe water required in commercial, healthcare, education, and industrial settings.

Our closed system water treatment services are designed to protect and prolong the life of heating, cooling, and process water systems. We treat and monitor the water within these systems to prevent corrosion, scale build-up, and microbiological fouling—all of which can significantly reduce system efficiency and increase energy costs. Using inhibitors, biocides, and smart diagnostics, we ensure your closed systems run at peak performance while maintaining compliance with BSRIA and CIBSE standards.

• Accredited Water Sampling
  Routine microbial and chemical sampling (e.g. TVC, Coliforms, E. coli, Pseudomonas).

• Monthly & Quarterly Compliance Visits
  Regular inspection, monitoring, and reporting tailored to HSG274 requirements.

• Asset Logbook Creation & Management
  Site-specific compliance documentation (including schematics and sampling plans).

• Risk-Based Monitoring Regimes
  Compliance schedules based on system risk profiling and usage patterns.

• Dead Leg Removal
  Pipework modifications to reduce stagnation risk.

• TMV Servicing & Replacement
  Thermostatic Mixing Valve fail-safes and compliance checks.

• Pipework Reconfiguration
