Verify Water Quality and Demonstrate Ongoing Compliance Between Risk Assessments
Legionella and Pseudomonas sampling provides laboratory confirmation that water systems remain safe and compliant between formal risk assessments. Conducted by NEBOSH-certified assessors and analysed by UKAS-accredited laboratories, the service validates the effectiveness of your ongoing control regime. Testing can be targeted to key outlets, sentinel points, or specific high-risk areas, with results interpreted and reported alongside professional recommendations.

Frequently Asked Questions
How often should Legionella water sampling be carried out?
Sampling frequency depends on your risk assessment and system type. Quarterly sampling is common for many buildings, with more frequent testing for healthcare or high-risk environments.
What is the difference between a risk assessment and water sampling?
A risk assessment evaluates system design, management and control measures. Water sampling provides laboratory confirmation that water quality meets safe standards between assessments.
What happens if Legionella is detected?
Results are interpreted and reported with clear recommendations for corrective action, which may include disinfection, flushing, or further investigation depending on the level detected.
Is Pseudomonas testing included?
Yes, Pseudomonas testing can be included alongside Legionella sampling, particularly for healthcare and clinical environments where HTM 01-05 compliance is required.
