A Legionella risk assessment identifies potential hazards within your water systems that could lead to the growth of Legionella bacteria. It’s a legal requirement for dutyholders, property owners, and facilities managers responsible for any building with water storage or circulation.

Our work follows the requirements of the Health and Safety Executive (HSE) and the Legionella Control Association (LCA).
1. Risk Assessment Record
The dutyholder must ensure there is a Legionella risk assessment record that includes all systems where water is stored or used in any premises controlled by the dutyholder (COSHH Regulations).
This risk assessment should be regularly reviewed to ensure it remains valid and reassessed when required.
(See L8 paras 32 and 47.)
2. Scope of Work for Service Providers
Any invitation to potential service providers to quote or tender for Legionella risk assessment services should have a clear scope of work defined by the dutyholder or their representative.
3. Proof of Competence
The dutyholder must make reasonable enquiries of the service provider regarding proof of competence of individuals carrying out the Legionella risk assessment — for example, through:
Training records
Competence evaluations
Examples of previous work
(See LCA Buyers Guide 702.17 06-17.)
4. Schematic Diagrams and Asset Registers
Schematic diagrams and asset registers should be available to inform and assist the risk assessor.
Pipework engineering drawings may be too detailed to communicate Legionella risk effectively, but schematic diagrams must show all details relevant to Legionella control.
(See L8 paras 38 and 40.)
5. Implementation of Findings
The findings of the risk assessment — including required corrective actions and control measures — must be implemented.
The output from the scheme of control should be recorded and used in any subsequent review of risk.
6. Written Scheme of Control
A written scheme of control must be produced, maintained, and regularly reviewed.
The output from this scheme should also be recorded and used in future risk reviews.
7. Regular Effectiveness Reviews
Regular reviews of the effectiveness of Legionella control activities should be carried out to verify that the written scheme of control remains adequate and up to date.
8. Change Management and Reassessment
The dutyholder should have change management procedures or regular review processes in place to determine whether the existing risk assessment remains valid, suitable, and sufficient.
If it is not, a reassessment of the risk is required.
We align every report with BS8580-1:2019, providing detailed documentation without unnecessary complexity.
