Professional Cleaning for Cold Water Storage Tanks

Once water is stored, it becomes exposed to surrounding environmental conditions. Without routine inspection and maintenance, tanks can develop sludge build-up and conditions that allow harmful microorganisms to grow.

Regular tank cleaning is recommended as part of a planned water hygiene programme, particularly for communal systems supplying multiple occupants.

We support the cleaning and disinfection of cold water storage tanks across a range of sectors, including:


🏢 Managing agents

🧱 Block management companies

🛠 Facilities management providers

🏘 Housing associations

🏗 Residential and mixed-use developments

🏨 Hotels and commercial premises

🏥 Care homes and healthcare environments

Frequently Asked Questions - Water Tank Cleaning

  • How often should water storage tanks be cleaned?

    Most communal cold water storage tanks should be inspected annually, with cleaning carried out as required based on tank condition and the site’s legionella risk assessment.


    Regular cleaning helps maintain water quality and supports compliance in multi-occupancy buildings.

  • Do you provide disinfection certificates?

    Yes. Following completion of cleaning and disinfection works, certification can be issued for dutyholder files, managing agent records, and audit requirements.

  • Do you specialise in apartment blocks and managed residential buildings?

    Yes — we regularly support managing agents, housing associations and facilities management providers responsible for communal systems.

  • Will residents lose water during the tank cleaning process?
