Legionella Risk Assessment
Professional Legionella risk assessments to manage water system compliance
BioSweep® UK provides professional Legionella risk assessments to help duty holders manage risks associated with water systems and comply with HSE guidance (ACOP L8 and HSG274). Our assessments identify potential sources of Legionella growth, evaluate system design and control measures, and provide clear, evidence‑based recommendations to protect occupants in residential, commercial, and institutional settings.
Why a Legionella Risk Assessment is Essential
Legionella bacteria can develop in man-made hot and cold water systems where environmental conditions allow growth. These include:
Stored water tanks and calorifiers
Hot and cold water distribution systems
Showers and spray outlets
Dead-leg pipework and stagnation points
Inadequate temperature control
Scale, corrosion and biofilm formation
Legionnaires’ disease is a potentially fatal form of pneumonia caused by inhaling fine water droplets contaminated with Legionella bacteria.
All commercial and rental properties with water systems carry potential risk if not properly assessed and controlled!
Legal Duties & Compliance
Under the Health and Safety at Work etc. Act 1974, the Management of Health and Safety at Work Regulations 1999, and associated legislation, employers, landlords and duty holders must:
Identify and assess sources of Legionella risk
Appoint a competent responsible person
Implement a written scheme of control
Maintain appropriate monitoring and records
Review assessments regularly
Failure to comply can result in enforcement action, fines, or prosecution.
A Legionella risk assessment provides documented evidence of due diligence and forms the foundation of your compliance framework.
