For landlords managing residential properties in the UK, understanding the legal requirements surrounding legionella risk assessments is crucial for ensuring both compliance and tenant safety.
This comprehensive guide will explore the legal obligations, practical implementation, and potential consequences of neglecting these vital safety assessments.
Do Landlords Have to Do a Legionella Risk Assessment?
Under the Health and Safety at Work Act 1974 and the Control of Substances Hazardous to Health Regulations 2002 (COSHH), landlords have a legal duty to assess and control the risk of exposure to legionella bacteria. This responsibility applies to both residential and commercial properties, requiring landlords to ensure their water systems are properly assessed and maintained to prevent the growth of harmful bacteria.
The Health and Safety Executive (HSE) specifically states that landlords must conduct risk assessments to identify and assess potential sources of exposure to legionella. While many landlords might question whether this applies to smaller residential properties, the legal requirement remains consistent regardless of property size or type.

What Does a Legionella Risk Assessment Involve?
A thorough legionella risk assessment examines various aspects of a property’s water system to identify potential risks and establish necessary control measures. The assessment typically focuses on conditions that promote bacterial growth, including water temperature, storage methods, and potential sources of contamination.
Consider the following data on optimal conditions for legionella growth and control measures:
| Water Temperature | Risk Level | Control Measures Required |
| Below 20°C | Low Risk | Regular monitoring |
| 20-45°C | High Risk | Implementation of control schemes |
| 45-60°C | Medium Risk | Temperature control required |
| Above 60°C | Low Risk | Scalding prevention needed |
Professional assessors will examine storage tanks, pipework, and outlets while documenting their findings and recommending appropriate control measures. This systematic approach ensures comprehensive coverage of all potential risk areas within the property’s water system.
Is a Risk Assessment a Legal Requirement?
The legal framework surrounding legionella risk assessments is unambiguous. The law requires landlords to assess the risk of exposure to legionella bacteria in their properties. This requirement stems from the landlord’s duty of care to ensure their properties are safe for occupation.
The Approved Code of Practice (ACoP) L8, published by the HSE, provides specific guidance on managing legionella risks. This document clearly outlines that the duty holder, in this case, the landlord, must ensure that the risk assessment is carried out by someone who is competent and understands the water systems and associated equipment.

What Happens If You Don’t Do a Risk Assessment?
Failing to conduct a legionella risk assessment can have serious consequences for landlords. The implications range from financial penalties to potential criminal charges, particularly if tenants become ill due to exposure to legionella bacteria.
The HSE has the authority to impose substantial fines for non-compliance, and these can escalate significantly if there’s evidence of deliberate neglect. In severe cases where legionella exposure leads to illness or death, landlords could face prosecution under the Health and Safety at Work Act, resulting in unlimited fines or even imprisonment.
Ensuring Compliance and Protecting Tenants
Understanding and implementing legionella risk assessments is fundamental to responsible property management. The assessment process not only ensures legal compliance but also demonstrates a commitment to tenant safety and well-being.
Key points to remember:
- Regular risk assessments are a legal requirement for all landlords
- Professional competency is essential for conducting thorough assessments
- Documentation and follow-up actions are crucial for maintaining compliance
Frequently Asked Questions About Legionella Risk Assessments
The HSE recommends reviewing risk assessments every two years or when significant changes occur to the water system. Regular reviews ensure continued effectiveness of control measures and compliance with current regulations.
While legally possible, landlords must demonstrate sufficient knowledge and competency to conduct accurate assessments. Professional assessors are recommended due to their expertise and understanding of complex water systems.
According to Wikipedia’s article on Legionnaires’ disease, symptoms typically include fever, cough, and difficulty breathing. The illness can be severe, particularly for vulnerable individuals, making prevention through proper risk assessment crucial.
Costs typically range from £150 to £400 for residential properties, depending on size and complexity. The investment is minimal compared to potential fines and legal consequences of non-compliance.
No properties are entirely exempt from the requirement to assess legionella risks. Even small properties with simple water systems require basic risk assessment and documentation.
Assessment records must include system description, potential risks, control measures, and monitoring procedures. All documentation should be readily available for inspection by relevant authorities.
A thorough assessment typically takes between 1-3 hours for residential properties. The duration depends on the property’s size and water system complexity.
All water systems require assessment, including hot and cold water storage, distribution pipes, and outlets. Special attention should be paid to rarely used outlets and dead legs in pipework.
Tenants must be given reasonable notice, but cannot indefinitely refuse access for safety assessments. Landlords should document all attempts to arrange access.
Professional assessors should complete recognised training courses and maintain current knowledge of regulations. Continuous professional development is essential for maintaining competency.
Additional assessments are necessary after significant changes to water systems, extended vacant periods, or reported cases of illness. Proactive monitoring helps maintain safety standards.
Regular maintenance, temperature monitoring, and cleaning of water systems help minimise risks. Simple preventive measures can significantly reduce the likelihood of bacterial growth.
Hot water should be stored at 60°C and distributed at 50°C minimum. These temperatures effectively prevent bacterial growth while considering scalding risks.
Holiday properties require particular attention due to irregular usage patterns. More frequent assessments and thorough flushing procedures may be necessary.
