Risk Assessments

"Current legislation and guidance states it is a requirement to document, manage and control the risk of Legionella exposure."

Risk assessments are formal, written documents that need to be carried out on hot and cold and cooling water systems. A risk assessment looks in detail at the water system and identifies all of the potential Legionella risks that are present or foreseeable. From the Legionella risk assessment a control scheme must be developed to ensure that all the risks identified are managed as efficiently as possible in order to reduce the level of risk within the system. Specific weekly, monthly, quarterly and annual tasks must be completed and recorded. 

Halpin & Hayward offer the full service to ensure compliance of risk assessment, log book supply, asset list generation and task scheduling to assist our clients in discharging their responsibilities.


The Legionella Risk Assessment is the blueprint for a Legionella Control Program. It is a thorough survey of a premises water services from where it enters the building until it leaves. It considers the installation and operation of the water system, plant and equipment on site to assess the potential risk of Legionella or other bacteria growth and ensure compliance to current law and best practice. The risk assessment document is presented in a concise report including photographic evidence, schematics, asset register, temperature profile and remedial action logs to aid clients with closing out any recommendations made.

It is the responsibility of the duty holders / building owners / facility managers to provide a safe environment for staff, visitors, contractors and the general public within their own facility but also consider their impact on nearby buildings.
