Legionella Risk Assessments for schools are an important step towards keeping children, staff and visitors safe from the risk of Legionella. This guide explains why schools are particularly at risk from Legionella, what the legal duties are and how schools can manage water safety with the right checks and support.
Why Schools Are at Risk from Legionella
Legionella bacteria can proliferate rapidly in warm, stagnant water within complex plumbing systems, conditions that are commonly found in school water systems. Extended periods of closure over summer holidays or half-term breaks can result in water remaining dormant within the pipework for weeks at a time, creating ideal conditions for Legionella bacteria to proliferate.
Older school buildings are particularly vulnerable, as aging and expansive plumbing infrastructure can make consistent water temperature monitoring considerably more challenging. High-risk areas within school water systems include showers, changing rooms, and science laboratories, where contaminated aerosol droplets can be released into the surrounding environment.
Where Legionella bacteria is allowed to proliferate and spread, children and older members of staff may be at greater risk of serious infection, including Legionnaires’ disease. This severe form of pneumonia is contracted through the inhalation of contaminated water droplets and can present with high fever, persistent cough, nausea, and in the most serious cases, life-threatening respiratory complications. This is why regular Legionella tests for schools are essential, not only to identify and mitigate risks at the earliest opportunity, but to ensure that the necessary remedial actions are implemented to protect the health and safety of all who use the facility.
Legal Duties and Requirements for UK Schools
Under the Health and Safety at Work Act 1974, duty holders within schools have a legal responsibility to manage and control the risks posed by Legionella bacteria within their water systems. The Health and Safety Executive provides statutory guidance through ACOP L8, and the HSG274 sets out the clear Legionella testing requirements that UK schools are obligated to follow.
The designated duty holder, typically a headteacher, business manager, or facilities manager, carries the day-to-day responsibility for ensuring that all identified risks from Legionella bacteria are effectively monitored, controlled, and documented.
Failure to comply with these obligations not only places the health and safety of students and staff at serious risk, but can also result in significant financial penalties, legal prosecution, and lasting reputational damage to the institution.
A professional Legionella Risk Assessment from H2O Hygiene ensures that duty holders have a clear and comprehensive understanding of the risks present within their water systems, along with the specific remedial actions required to maintain compliance and keep water systems safe from the proliferation of Legionella bacteria.
Legionella Risk Assessment in Schools – What’s Covered?
Legionella Risk Assessments in schools do not in themselves ensure compliance, but they are a fundamental first step in identifying risks within your water systems and providing the clear, actionable recommendations required to achieve and maintain it. The assessment process follows several key stages:
- A comprehensive survey of all water systems – including water temperature checks and physical inspections of all water-bearing assets
- Identification of high-risk areas – with particular attention given to infrequently used outlets and areas where stagnation within the pipework may be present
- Review of existing management controls – evaluating the effectiveness of procedures and controls already in place within the facility
- A detailed written report – outlining all identified areas of concern and providing clear, prioritised remedial recommendations
The findings from Legionella Risk Assessments in schools will typically prompt a range of remedial actions, which may include implementing regular flushing regimes, upgrading ageing water system components, or improving monitoring through routine water temperature checks. Consistently acting upon these recommendations ensures that your school is in the strongest possible position to control and mitigate the risks of Legionella bacteria proliferating within its water systems.
How Often Should Schools Conduct a Legionella Risk Assessment?
The frequency in which your water systems should be assessed is determined by the nature of your building and how it is used. As a general guideline, a Legionella Risk Assessment should be conducted at least once every two years, or sooner where any of the following circumstances apply:
- Significant changes to the building layout or water systems – any alterations to pipework or water-bearing assets may introduce new areas of risk
- Extended periods of closure – such as during prolonged school holidays, where water may have remained stagnant within the pipework for an extended period
- Evidence that existing control measures are ineffective – where monitoring indicates that temperatures or other parameters are not being consistently maintained
- A confirmed or suspected outbreak of Legionella – immediate reassessment is essential to identify the source and prevent further proliferation
It is the duty holder’s legal responsibility to ensure that all staff, students, and visitors are protected from the risks of Legionella, and regular assessments are fundamental to identifying and addressing any emerging risks in a timely manner.
In healthcare environments such as hospitals and care homes, additional and heightened consideration must be given to residents and patients who are exposed to water systems, as those with pre-existing respiratory conditions or compromised immune systems face a significantly elevated risk of serious illness or fatality should Legionella bacteria be allowed to proliferate within the facility’s water systems.
Best Practices for Ongoing Legionella Control in Schools
The designated Responsible Person within the school, should ensure that regular Legionella Risk Assessments are commissioned through a qualified and competent water hygiene company such as H2O Hygiene. These assessments must be carried out by competent professionals who are equipped to thoroughly evaluate risks within the water systems and provide clear, prioritised remedial recommendations.
In addition to formal assessments, schools should implement a range of day-to-day control measures to manage the risks of Legionella proliferating within their water systems. These include maintaining accurate records and logbooks of all monitoring activities, conducting routine water temperature checks, and implementing a structured flushing regime for infrequently used outlets, particularly following extended periods of closure.
It is equally important to ensure that all relevant staff members are fully aware of the risks associated with Legionella and their responsibilities in managing them. Regular training is strongly recommended, particularly in environments where there is a high turnover of staff, to ensure that water hygiene protocols are consistently understood, followed, and documented at all times.
