Protect your employees, visitors and business with a professional Legionella Risk Assessment from Principal Hygiene. We provide fully compliant Legionella testing, water hygiene services and risk assessments for businesses across the UK, helping you meet your legal obligations while reducing the risk of Legionnaires’ disease.
Legionella bacteria can develop in poorly maintained water systems and, if left untreated, can cause Legionnaires’ disease, a serious and potentially fatal form of pneumonia. UK health and safety legislation places a legal duty on employers, landlords and those responsible for premises to assess and control this risk.
The Health and Safety Executive (HSE) recommends that Legionella Risk Assessments are reviewed regularly and whenever significant changes are made to your water system.

Why Legionella Control Matters
According to UK public health data, hundreds of cases of Legionnaires’ disease are reported every year, with around 10% proving fatal.
Legionella bacteria multiply in stagnant or poorly maintained water systems, particularly where temperatures range between 20°C and 45°C. Regular monitoring, maintenance and professional risk assessments are essential to reducing the risk of outbreaks and protecting building occupants.
