Water Quality Monitoring Services
Enviroteam provides professional Water Quality Monitoring services to help
organisations maintain safe, compliant and well-managed water systems across
commercial and industrial sites in the UK.
Our monitoring programmes support Legionella control and wider water hygiene
management by identifying potential risks early, verifying system performance
and providing clear compliance records for audit and regulatory purposes.
What is Water Quality Monitoring?
Water quality monitoring involves the routine inspection, measurement and analysis of key parameters within water systems to ensure they remain safe and fit for use. Monitoring helps detect conditions that could promote bacterial growth, contamination or system deterioration and provides evidence that control measures are working effectively.
Monitoring forms a core part of Legionella control and is aligned with UK health and safety guidance including ACoP L8 and HSG274.
Our Water Quality Monitoring Services
Temperature Monitoring
Routine temperature checks at representative outlets and critical system points within hot and cold water systems to confirm conditions are outside ranges that support Legionella growth.
Outlet Servicing & Hygiene Checks
Cleaning, descaling and inspection
of showers, spray taps and other outlets to maintain hygiene and system performance.
Tank, Heater & Calorifier Inspections
Inspection of cold water storage tanks, calorifiers and heaters to identify scale, sediment, stagnation and signs of contamination.
Trend Analysis & Reporting
All monitoring data is recorded and analysed to identify patterns over time, allowing emerging risks to be addressed before they become compliance failures.
Thermostatic Mixing Valve
(TMV) Testing & Servicing
Testing and servicing of TMVs to verify correct temperature control and safe operation at outlets.
Effective monitoring allows organisations to:
Identify emerging risks early
Support Legionella risk assessments with measured data
Demonstrate compliance with legal duties
Protect building occupants and the public
Maintain efficient and reliable water systems

Frequently Asked Questions (Water Monitoring)
What is water quality monitoring?
1
Water quality monitoring is the routine checking of water systems to assess conditions such as temperature, hygiene and system performance. It helps manage risks, support compliance and protect users.
How often should water quality be monitored?
2
Monitoring frequency depends on system complexity and risk level. Many commercial water systems require monthly or quarterly checks, with additional monitoring for higher-risk systems.
Who is required to carry out monthly temperature monitoring?
3
Monthly temperature monitoring is required for organisations that operate hot and cold water systems where Legionella risk is present and where monitoring is identified as a control measure within the Legionella risk assessment.
This commonly applies to Duty Holders responsible for water systems in higher-risk or complex environments such as:
Healthcare and care homes
Hotels and leisure facilities
Education buildings
Large commercial or industrial premises
Buildings with stored water, calorifiers or complex distribution systems
Temperature monitoring forms part of the routine control measures recommended in HSE guidance (including HSG274) to verify that water systems are operating outside temperature ranges that allow Legionella bacteria to grow.
Does monitoring support Legionella compliance?
4
Yes. Monitoring data supports Legionella risk assessments, verifies that control measures are effective and provides evidence of due diligence under UK health and safety legislation.
What parameters are typically monitored?
5
Monitoring commonly includes water temperature, system condition, outlet hygiene and the performance of components such as TMVs.
Do you provide compliance reports?
6
Yes. All services include structured reports showing results, compliance status and recommendations for action.
Can monitoring be combined with other services?
7
Yes. Monitoring can be integrated with water hygiene services, Legionella risk assessments, cooling tower and tank cleaning, engineering works and training.
Do you provide nationwide coverage?
8
Yes. Enviroteam provides water quality monitoring services across the UK for commercial and industrial clients.
