Water Risk Assessments & Legionella Control

Ensuring Safety, Compliance, and Water Hygiene

Water safety is a critical component of building management. At HF, we provide comprehensive Water Risk Assessments with a core focus on Legionella prevention. Our mission is to ensure that your facility’s water systems are not only efficient but fully compliant with the HSE’s ACoP L8 (Approved Code of Practice) and HSG274 guidelines.

From small commercial units to large-scale industrial complexes and residential portfolios, we provide the technical expertise required to identify, manage, and mitigate the risks associated with water-borne pathogens.Understanding the Risk: Legionella

Legionella bacteria can flourish in managed water systems where temperatures are between 20°C and 45°C and where there is a source of nutrients (such as scale, rust, or biofilm). If contaminated water droplets are inhaled—via showers, spray taps, or cooling towers—it can lead to Legionnaires’ Disease, a severe form of pneumonia.

Our Water Hygiene Services Include:

• Comprehensive Risk Assessments: A full physical inspection of your water system, including storage tanks, calorifiers, and pipework dead-legs.
• Temperature Monitoring & Testing: Regular logging of water temperatures to ensure they remain outside the “danger zone” for bacterial growth.
• Bacteriological Sampling: Independent UKAS-accredited laboratory analysis for Legionella and other water-borne bacteria.
• System Disinfection & Chlorination: Professional cleaning and chemical treatment of tanks and services following new installations or periods of stagnation.
• Remedial Engineering: Our mechanical teams can swiftly resolve “high-risk” findings, such as removing redundant pipework or insulating storage tanks to maintain thermal control.
• Schematic Drawing Updates: Providing accurate, up-to-date drawings of your water infrastructure, a legal requirement for compliance.

Total Compliance Management

Managing water risk is an ongoing process, not a one-time event. HF provides a “Closed Loop” service that takes you from initial assessment to full remediation.

1. The Assessment: Our qualified assessors identify potential hazards and evaluate the level of risk to staff and visitors.
2. The Written Scheme: We provide a bespoke management plan (the “Written Scheme of Control”) detailing the specific actions required for your site.
3. The Solution: Unlike standalone consultancy firms, HF can immediately deploy engineers to fix physical defects, replace failing water heaters, or install Temperature Maintenance Systems.
4. The Record: We help you maintain a robust Compliance Log Book, providing the “Single Source of Truth” needed for health and safety audits.

Why Choose HF for Water Safety?

• Technical Excellence: Our engineers understand the mechanics behind the hygiene. We don’t just find problems; we engineer the solutions.
• Integrated Services: We work alongside our Automated Controls team to implement remote temperature monitoring systems, reducing the need for manual site visits.

Legal Duty of Care

If you are an employer or a landlord, you are legally required to understand the health risks associated with your water systems. Failure to comply with ACoP L8 can lead to significant fines and legal liability. Let HF handle the complexity of water hygiene, allowing you to focus on your core business with total peace of mind.
