Cold Water Storage Tank Maintenance & Legionella Compliance
Premium Service by RARE Plumbing London
In prestigious London homes and commercial properties, peace of mind begins with confidence in the unseen systems that keep your environment safe, clean, and running efficiently. One of the most critical—yet often overlooked—components of your water infrastructure is the cold water storage tank. At RARE Plumbing London, we offer comprehensive, high-end maintenance and cleaning services designed to meet the highest standards of safety, hygiene, and performance.
Our team specialises in maintaining residential and commercial tanks across luxury homes, heritage buildings, boutique hotels, restaurants, and managed estates—ensuring water quality remains uncompromised, year-round.
💧
The Role of Cold Water Storage Tanks in Modern Properties
Many of London’s finest properties still rely on traditional cold water storage systems. These tanks provide a steady water supply and pressure, particularly in older or larger buildings where demand fluctuates. But without regular, expert care, these systems can become a silent risk—harbouring bacteria such as Legionella and compromising your water quality.
🛡️
Why Maintenance is Non-Negotiable
At RARE, we approach tank maintenance with the same care and detail we’d apply to a fine renovation or bespoke installation. Our priority is to ensure your water supply remains:
✔ Safe for use – Free from harmful bacteria and contamination
✔ Efficient – Clear of blockages or sediment that hinder performance
✔ Compliant – Meeting all health and safety standards for private and commercial properties
Common risks in neglected tanks include:
• Legionella proliferation in stagnant or warm water
• Biofilm buildup and sediment, which affect water clarity and hygiene
• Leaks, corrosion, or cracks compromising the tank structure
• Temperature fluctuations that fall within Legionella risk range (20°C–45°C)
🔍
Legionella: Silent, But Serious
Legionella thrives in still, warm water—and when conditions are right, it can spread via water vapour, causing Legionnaires’ disease: a potentially fatal form of pneumonia. Our luxury clients trust RARE to detect, prevent, and eliminate this risk with precision, confidentiality, and efficiency.
Your cold water tank may be vulnerable if:
• It’s rarely cleaned or inspected
• Water remains stagnant or unflushed
• Biofilms have formed inside the tank
• Insulation is inadequate

Legionella Risk Assessment & Reporting
Landlords, commercial clients, and estate managers are required by law to undertake regular Legionella risk assessments. RARE Plumbing offers fully certified, comprehensive assessments, ideal for:
• Residential lettings
• Private healthcare and care homes
• Boutique hospitality venues
• Office buildings and commercial units
Our assessments include:
• Full cold water system inspection (tanks, outlets, and pipework)
• Temperature testing at key points
• Risk reporting with photographic evidence
• Expert recommendations to maintain HSE compliance (ACoP L8)
🗓️
How Often Should Tanks Be Cleaned?
At a minimum, annual tank cleaning is advised. However, larger or more sensitive environments—such as schools, clinics, or hospitality properties—may require more frequent inspections.
Routine cleaning offers:
• Safer water, free from bacterial buildup
• Better system longevity and efficiency
• Regulatory peace of mind
