Why Domestic Water Tank Cleaning is Essential for Your Health and Home

At Green Water Services, we specialise in professional water tank cleaning services for homes across the UK. Whether you live in a rural property with a dedicated storage tank or a domestic residence with a loft tank, regular cleaning is vital to ensure your water remains clean, safe, and compliant with health guidelines.

Many homeowners are unaware that over time, domestic water tanks can become contaminated with debris, biofilm, bacteria, and even pests. This build-up not only compromises water quality but can also pose serious health risks to you and your family.

What Happens if You Don’t Clean Your Water Tank?

Neglecting domestic water tank cleaning can lead to the accumulation of:

  • Sediment and scale from pipe corrosion
  • Biofilm, which can harbour harmful bacteria
  • Legionella bacteria, linked to Legionnaires’ disease
  • Algae growth, particularly in tanks exposed to sunlight
  • Rodents or insects, entering through unsealed lids or vents

Contaminated water can affect everything from drinking and bathing to laundry and cleaning. Even if the water looks clear, it might not be safe.

Why You Should Use Professional Water Tank Cleaning Services

DIY cleaning may seem like a cost-saving option, but without the correct equipment and knowledge, it’s easy to miss hidden hazards or cause damage to your system. That’s why using a qualified provider like Green Water Services is the safest, most effective solution.

Our domestic water tank cleaning services include:

  • A full inspection and risk assessment
  • Isolating the tank and flushing the system
  • Removing sediment, sludge, and scale
  • Disinfecting with approved chemicals to kill bacteria and algae
  • Rinsing, refilling, and recommissioning the tank
  • Providing a post-cleaning hygiene certificate for your records

We work in full compliance with HSE ACoP L8 and BS 8558:2015 standards, ensuring your water tank is cleaned to industry-best practice. Our experienced team uses safe, non-invasive methods and always works with minimal disruption to your home.

How Often Should a Domestic Water Tank Be Cleaned?

For most households, we recommend a full clean once every 12 months. However, if your water tank is old, rarely used, or you notice signs of contamination—such as unusual smells, discolouration, or sediment—you may need more frequent cleaning.

If you’re unsure, our expert engineers can assess your tank and advise on the best maintenance schedule for your property.
