Keeping your water tank clean is essential to protect health, meet legal compliance, and ensure your water system runs efficiently. At Green Water, we provide trusted UK water tank cleaning services for both commercial and domestic systems. Our experienced team ensures your water tanks remain safe, hygienic, and compliant with all current Health and Safety regulations, including HSE and ACOP L8 guidance.
What Is Water Tank Cleaning?
Water tank cleaning is the process of draining, disinfecting, and removing sediment or biofilm from cold water storage tanks. These tanks are commonly found in homes, flats, hospitals, schools, offices, and industrial buildings. Without proper maintenance, water tanks can become contaminated with dirt, scale, or bacteria such as Legionella, which can pose a serious health risk.
Our professional tank cleaning process includes:
- Draining the tank
- Removing debris and sediment
- Cleaning with approved disinfectants
- Treating any biofilm layers
- Refilling and issuing a Chlorination Certificate
Why UK Water Tank Cleaning Is So Important
If your water tank isn’t cleaned regularly, it can develop harmful bacteria, especially if the water becomes stagnant or the system isn’t in use for long periods. Contaminated tanks may result in poor water quality or contribute to the growth of Legionella bacteria, which can lead to Legionnaires’ disease.
Regular water tank cleaning ensures:
- Compliance with Health and Safety regulations
- Clean, safe water for residents and staff
- Protection from bacterial growth
- A longer-lasting, more efficient system
At Green Water, we tailor our services to your tank size, location, and building type; from single domestic properties to large-scale commercial sites.
When Should a Water Tank Be Cleaned?
You should consider UK water tank cleaning if:
- Your tank has visible debris, scale, or signs of corrosion
- A Legionella Risk Assessment recommends it
- The water system has been unused for a long period
- The water’s pH level has moved outside the safe range
- The tank is missing a lid or is not adequately insulated
As a general guideline:
- Potable (drinking) water tanks should be cleaned annually
- Non-potable systems typically require cleaning every 2 to 3 years
We’ll advise the most suitable schedule based on inspection results and water hardness in your area.

- Lofts and attics
