Monitoring for Legionella


Your legionella risk assessment will identify all your legionella monitoring, control and management requirements. This will include a range of water monitoring, servicing and inspection tasks throughout the year.

Legionella monitoring focuses on improving the management of your water system by creating records of periodic tasks. As an example, recording monthly temperatures provides you with a tool that can show you when your temperatures are compliant or falling short and allows you to interpret why and what changes need to be made to ensure your temperatures remain in the compliant ranges.

Water monitoring include tasks such as weekly flushing, monthly temperatures, quarterly de-scaling, TMV servicing, cold water storage tank inspections and hot water cylinder inspections and so on. We are pleased to now be able to offer both on-site & remote water monitoring for your convenience.  

Why do I need to do water monitoring?


Under the Health and Safety at Work Act 1974 and in compliance with the Approved Code of Practice (ACoP L8, HSG 274), duty holders, including employers and those in control of premises, must ensure the health and safety of their employees or others who may be affected by their undertaking.

This includes taking suitable precautions to prevent, manage and control the risk of exposure to legionella. You can do this by undertaking the following: a legionella risk assessment, actioning all identified risks within the risk assessment with legionella remedial works, sampling the water quality to confirm bacterial presence with legionella testing, and carrying out ongoing record keeping also known as legionella monitoring or water monitoring.

Take our online legionella training course for a better understanding of the compliance needed.

When and how often do I need legionella monitoring?


Following a legionella risk assessment a water logbook should be produced to aid with your legionella monitoring and record keeping. Each water system is different and therefore will require a bespoke water monitoring plan. Typically tasks should be undertaken weekly, monthly, quarterly, six monthly and annually.

Examples of Water Monitoring Tasks


Weekly Flushing Regime

Cold Water Tank Inspection



Monthly Temperatures

Hot Water Cylinder Inspection

Water Sampling


Quarterly De-scaling

TMV Servicing


TMV Failsafe Testing

Expansion Vessel Servicing

How much does water monitoring cost?


water monitoring prices vary depending on the number of water outlets, cold water storage tanks, hot water cylinders, combi boilers and other water assets that may be present. The number of assets within your water system will determine the time spent on site and how long it will take to carry out all legionella monitoring tasks.

So how much does a water monitoring cost? Across the industry prices vary enormously often depending on the size of the company you use and their processes, speed of works and professionalism.

uRisk carries out price comparison and reviews regularly to ensure our prices are kept competitive and with the customer in mind.

How long does a water monitoring visit take?


Depending on the type of water monitoring visit it is and the size of the water system will determine how long a water hygiene engineer is on site for. For monthly temperature monitoring you can expect the engineer to be on site for a period of 30-60 minutes on average. However, if the tasks are quarterly de-scaling you might expect the engineer to be present for 1-4 hours.

Other tasks such as TMV servicing and inspections can take considerably longer due to the nature of the works.


How long are water monitoring contracts?


Legionella monitoring contracts at uRisk range from 2 to 5 years. In special circumstances we offer 12-month contracts, but the longer the contract the better price we can offer you.

What if I choose not to do legionella monitoring?


It is your legal responsibility under HSE ACOP L8 (HSG 274) to ensure the safety of those at your place of work or property. Should you choose not to undertake water monitoring, you run the risk of allowing harmful bacteria to grow within your water system which may lead to illness and prosecution.
