Legionella Risk Assessment Services

Legionella Risk Assessment Services

Under UK health and safety legislation, dutyholders are required to assess and manage the risks associated with Legionella bacteria in water systems. Midlands Chlorination Services provides professional Legionella risk assessments for commercial and industrial premises in accordance with HSE ACoP L8 and HSG274 Part 2.

Our assessments include an evaluation of hot and cold water systems, identification of potential risk factors and an assessment of existing control measures. A detailed report is provided, highlighting any deficiencies and offering practical recommendations to help dutyholders manage Legionella risks and meet their legal obligations.

A Legionella risk assessment is a legal requirement under UK health and safety law. It supports health protection, improves risk visibility, and ensures your systems remain compliant and efficiently managed.

A Legionella risk assessment is essential for legal compliance, health protection, risk management, efficient resource use, and ongoing regulatory compliance.
