Legionella Control & Management
With an estimated 4,000 to 6,000 cases of Legionnaires' disease in the UK each year, effective water system management is critical. Protect your building occupants with proven chlorine dioxide treatment that penetrates biofilm where Legionella harbours.
Why Legionella Management Matters
An estimated 4,000 to 6,000 cases of Legionnaires' disease occur in the UK annually, often linked to poorly designed, installed, or maintained water systems (CIPHE). Effective Legionella control is both a legal requirement and essential for protecting building occupants, particularly in healthcare, hospitality, and commercial premises used by vulnerable people.
Healthcare Facilities
Hospitals, care homes, and dental practices require stringent Legionella management to protect vulnerable patients.
- HTM 04-01 compliance
- Continuous monitoring
- Risk assessment updates
Hotels & Hospitality
Water systems in hotels, gyms, and leisure centres require regular Legionella risk management.
- ACOP L8 compliance
- Guest safety protocols
- Shower & spa treatment
Cooling Towers
Industrial cooling systems are high-risk for Legionella proliferation and require specialist treatment.
- HSG274 Part 1 compliance
- Regular monitoring
- Biocide treatment
Commercial Buildings
Office blocks, shopping centres, and public buildings must manage water system Legionella risks.
- Written scheme of control
- Temperature monitoring
- Dead-leg management
UK Legal Requirements
Under ACOP L8 and the Health and Safety at Work Act 1974, employers and duty holders must assess and control Legionella risks in water systems. Failure to comply can result in prosecution, unlimited fines, and imprisonment.View compliance requirements
Effective Legionella Control Solutions
A comprehensive Legionella management programme combines multiple control measures. Chlorine dioxide treatment provides the most effective chemical control available.
Chlorine Dioxide Treatment
The most effective chemical treatment for Legionella control. ChloroKlean's liquid chlorine dioxide penetrates biofilms where Legionella harbours, providing superior control compared to traditional chlorine.
- Biofilm penetration
- No THM formation
- Effective at low doses
- Wide pH range
Temperature Control
Maintaining hot water above 60°C and cold water below 20°C is fundamental to Legionella management, but often insufficient alone.
- Primary control method
- ACOP L8 requirement
- Regular monitoring needed
- Energy considerations
Risk Assessment
Regular Legionella risk assessments identify potential hazards and ensure control measures are effective and up to date.
- Legal requirement
- Identifies hazards
- Informs control scheme
- Regular review needed
Superior Legionella Treatment with ClO₂
Chlorine dioxide is recognised as the most effective chemical treatment for Legionella control. ChloroKlean's liquid products make professional treatment accessible without expensive equipment.
Biofilm Penetration
Legionella bacteria colonise biofilms that protect them from traditional treatments. Chlorine dioxide's unique chemistry allows it to penetrate and destroy these protective layers.
Proven Efficacy
Independent studies demonstrate chlorine dioxide achieves 99.99% Legionella reduction. Our case studies show consistent results across healthcare and commercial applications.
No Generators Required
ChloroKlean products are liquid chlorine dioxide that activate in-situ without expensive generator equipment, making professional Legionella control accessible to all facilities.
BPR Compliant
All ChloroKlean products are GB BPR compliant, ensuring you meet regulatory requirements for Legionella control in the UK.
Low Corrosion
Chlorine dioxide is less corrosive than chlorine at equivalent biocidal concentrations, protecting pipework and extending system life.
Maintained Residual
Provides ongoing protection throughout the water distribution system, not just at the point of dosing.
