Water Testing and Legionella Risk Assessments for Schools
One important but sometimes overlooked aspect of health and safety in schools is managing the risk of Legionella. These waterborne bacteria can develop in poorly managed hot and cold water systems and may cause Legionnaires’ disease, a serious form of pneumonia. Because of this, Legionella risk assessments in schools are a key part of maintaining safe facilities and ensuring compliance with UK Health and Safety regulations.
We specialise in Legionella risk assessment for schools, colleges, and universities across the UK. Our experienced team helps education providers maintain compliance while supporting effective Legionella prevention in schools through tailored services and clear reporting.
If you are responsible for health and safety in a school, our specialists are here to help. Speak to our team today for expert guidance or book a service for your site as soon as possible.

Do Schools Have to Do Legionella Risk Assessments?
Yes. Under the Health and Safety at Work etc. Act 1974, organisations that control premises must identify and manage risks associated with Legionella bacteria. This means that schools in the UK must carry out a Legionella risk assessment and implement suitable control measures.
Guidance is provided by the Health and Safety Executive through ACOP L8 and HSG274, which outline the responsibilities for preventing Legionella growth in water systems. Schools are required to assess potential hazards, put management procedures in place, and regularly review their water systems.
Who is Responsible for Legionella Control in Schools?
Responsibility for Legionella prevention in schools typically sits with the organisation that controls the premises.
For local authority-maintained schools, the local authority often holds overall responsibility for water safety compliance. In academies and free schools, this duty usually falls to the academy trust or governing body.
However, day-to-day management of water systems is commonly delegated to a designated Responsible Person. This may include:
- Facilities managers
- Site managers
- School business managers
- Health and safety coordinators
The Responsible Person must ensure the school’s water systems are properly monitored, documented, and maintained. Many schools choose to work with professional Legionella specialists to ensure these responsibilities are handled correctly and efficiently.
What is the Noting Down Policy for Legionella in Schools?
Some schools also develop a Legionella policy outline as part of their wider health and safety framework, noting their best practices for parents and caregivers. These typically cover how water systems are monitored, maintained, and tested to reduce the risk of Legionella bacteria developing. Having one available for your school allows everyone to see how your own practices are carried out and when.

Why Are Legionella Risk Assessments Important For Schools?
Schools present several unique conditions that can increase the risk of Legionella in schools in the UK.
Educational facilities often have:
- Large buildings with complex plumbing systems
- Multiple water outlets across classrooms, kitchens, and sports facilities
- High levels of daily water usage
- Showers and changing room facilities
- Drinking fountains and handwashing stations
Additionally, school holidays and periods of reduced building use can cause water stagnation, which creates conditions where Legionella bacteria may grow. Older buildings can also present challenges, particularly where legacy pipework or outdated water systems are present.
A Legionella risk assessment for schools identifies these risks and guides how to manage them effectively.
What Water Systems in Schools are at Risk of Legionella?
Because Legionella bacteria thrive in warm, stagnant water, many common systems within schools require monitoring.
Areas commonly assessed during water testing in schools include:
- Showers and changing room facilities
- Hot and cold water taps
- Drinking fountains
- Cold water storage tanks
- Calorifiers and hot water cylinders
- Pipework containing dead legs
- Spray taps or misting systems
- Air conditioning and cooling systems
These systems can generate fine water droplets known as aerosols, which can allow Legionella bacteria to spread if contamination occurs. Regular Legionella tests for schools help identify potential problems early and ensure systems remain safe.
How Often Should Legionella Testing Be Done in Schools?
Legionella risk assessments should be formally reassessed when there are significant changes to ensure that the assessment remains valid, for example, when there are:
- Changes to the water system or its use;
- Changes to the use of the building or part of the building in which the system is installed;
- The availability of new information about risks or control measures;
- Indications that control measures are no longer effective;
- New construction works or system modifications planned; or
- Changes to the key personnel, contractors and service providers.
- A case of Legionnaire’s Disease / Legionellosis associated with the system
Where a reassessment has not been triggered by the above, there should be a policy of planned reassessment in place.
Water systems with higher inherent risk or complex water services where changes are poorly documented may need to be reassessed frequently, e.g. annually. For water systems with a lower inherent risk, or those where all changes are recorded and where systems are well managed, it may be sufficient for a formal reassessment to be performed every 2 to 5 years.
The risk assessor will determine a reassessment frequency based on the current and expected future risk and will note it in the assessment.
Legionella Testing in Schools
In addition to risk assessments, many schools implement ongoing Legionella testing as part of a comprehensive water management programme. This may include:
- Temperature monitoring of hot and cold outlets
- Water sampling and laboratory testing
- Tank inspections and cleaning
- Shower cleaning and disinfection
- Routine system checks
These measures support effective Legionella prevention in schools and ensure compliance with regulatory guidance.
How We Carry Out Legionella Risk Assessments for Schools
A professional Legionella risk assessment for schools involves a detailed inspection of the building’s water systems and management procedures.
During an assessment, our specialists will typically:
- Conduct a full survey of the water system
- Identify areas where Legionella bacteria could develop
- Carry out temperature testing at key outlets
- Inspect cold water tanks and hot water systems
- Review logbooks and maintenance records
- Take water samples for Legionella testing where required
While some schools may search for a Legionella risk assessment template to carry it out themselves, a professional assessment provides the most reliable and compliant approach.
What Happens After a Legionella Risk Assessment?
Following the assessment, we’ll compile our findings into a detailed report, outlining risk levels and recommended actions. The report may include guidance on improvements to water management procedures, system upgrades, or additional monitoring requirements. If remedial work or ongoing services are recommended, our team can support schools with a full range of solutions, including:
- Legionella monitoring programmes
- Further water sampling and testing
- Disinfection of hot and cold water systems
- Legionella control schemes
- Remedial Legionella works
Our goal is to help schools maintain safe water systems while ensuring full regulatory compliance.
