An outbreak of Legionella in schools places pupils, staff, and visitors at serious risk of contracting Legionnaires’ disease, a severe and potentially fatal form of pneumonia. It is therefore essential that schools develop a comprehensive Legionella Risk Assessment management plan and maintain ongoing monitoring and control measures to keep risks to an absolute minimum.
1. Understand Your Legal Duties
Schools in the UK have clear and statutory responsibilities under the Health and Safety at Work Act 1974 to effectively manage Legionella risks within their water systems. The Health and Safety Executive (HSE), through ACOP L8 and HSG274, sets out the specific steps schools must take to prevent Legionella in schools and protect all those who use the facility.
The designated duty holder, typically the headteacher, governor, or facilities manager, is legally responsible for ensuring that Legionella risks are identified, controlled, and documented through regular risk assessments. Non-compliance with these obligations can result in serious consequences, including substantial financial penalties, criminal prosecution, and lasting reputational damage to the institution. A thorough understanding of your legal duties is the essential foundation upon which a robust Legionella Risk Assessment management plan must be built.
2. Appoint a Responsible Person or Partner with a Specialist Company
All school premises must appoint a designated Responsible Person to fulfil the legal and moral obligations of the building. This individual must assume day-to-day responsibility for managing Legionella risks and must have a thorough working knowledge of the water systems on site, including all associated equipment such as pumps, calorifiers, and heat exchangers.
With regard to water safety, the Responsible Person must ensure that regular school Legionella Risk Assessments are commissioned, water temperature monitoring is carried out consistently, maintenance is coordinated effectively, and accurate records are maintained at all times. Competency and appropriate training are fundamental requirements of this role to ensure both legal compliance and effective ongoing management of Legionella in schools. Where the school does not have a suitably competent individual in-house, an external specialist such as H2O Hygiene can be appointed to fulfil this function.
3. Conduct a Legionella Risk Assessment
A school Legionella Risk Assessment conducted by H2O Hygiene follows a structured and thorough process, encompassing the following key stages:
- Identification of all water sources – including taps, showers, tanks, and all other water-bearing assets across the facility
- Identification of high-risk areas – with particular focus on infrequently used outlets and areas where stagnation within the pipework may be present
- Mapping of the entire water system – producing a detailed schematic drawing to facilitate ongoing management and monitoring
- Water temperature monitoring – verifying that temperatures are being maintained within the parameters required for effective Legionella control
- Production of a detailed written report – outlining all identified risks and providing clear, prioritised, and actionable recommendations
The frequency with which school Legionella Risk Assessments should be conducted is determined by the nature and use of the building. As a general guideline, assessments are typically required at least once every two years or sooner where significant changes to the building layout or water systems have been made following extended periods of closure or in the event of a confirmed or suspected Legionella outbreak.
4. Develop and Implement Control Measures
It is important to recognise that a risk assessment alone does not prevent Legionella in schools. The Legionella Risk Assessment identifies areas of concern within the water systems and provides specific remedial recommendations that must be acted upon to maintain compliance and protect all building occupants. Once risks have been clearly identified, appropriate control measures must be implemented without delay. These may include:
- Regular flushing of infrequently used outlets to prevent stagnation within the pipework
- Routine monitoring and maintenance of water temperatures to ensure they remain within safe parameters
- Cleaning and disinfection of storage tanks and outlets to prevent the proliferation of Legionella bacteria
- Review and remediation of system design to eliminate dead legs and other areas of stagnation
Implementing these preventative measures is considerably more effective, and less costly, than responding to a Legionella outbreak after it has occurred. Acting upon the recommendations provided within your school Legionella Risk Assessment is fundamental to keeping your water systems safe and your premises fully compliant.
5. Set Up Monitoring and Record-Keeping
Ongoing monitoring is an essential component of any effective Legionella Risk Assessment management plan, and records must be maintained and kept fully up-to-date at all times. The Responsible Person should ensure that the following are consistently tracked and documented:
- Water temperatures across all outlets throughout the facility
- Usage patterns, with particular attention given to infrequently used outlets and dead legs within the pipework
- Regular cleaning, flushing, and maintenance schedules and their completion
Accurate and up-to-date records provide critical evidence of compliance and may be required during inspections by governing bodies or regulatory authorities. Utilising digital logbooks and management tools can streamline this process, making ongoing school Legionella tests and day-to-day monitoring considerably more manageable.
6. Provide Training and Awareness
It is best practice to ensure that all staff members involved in the management of water systems, alongside the designated Responsible Person, receive appropriate training in understanding the risks of Legionella in schools and how to carry out correct maintenance and monitoring routines. When staff are equipped to identify early warning signs, such as abnormal water temperatures or inadequate flushing regimes, this significantly reduces the likelihood of Legionella bacteria proliferating within the water systems.
Water hygiene training can be delivered in-house or by an external specialist provider such as H2O Hygiene. Our training programmes ensure that your staff remain vigilant in the day-to-day management of water systems and are fully informed of the serious risks posed by Legionnaires’ disease to the pupils, staff, and visitors in your care.
7. Review and Update the Plan
Once the Legionella Risk Assessment management plan has been established, schools must ensure it is reviewed and updated on a regular basis, following every risk assessment, system modification, change in key personnel, or update to relevant health and safety legislation and guidance.
Keeping all documentation current ensures that your premises are fully prepared for inspections by governing bodies and demonstrates a proactive and conscientious approach to compliance. Regular reviews also serve to minimise risk and protect the health and safety of every pupil, member of staff, and visitor who enters your facility.
