Cleaning & Disinfecting

Clean, well-maintained water systems are an important part of Legionella control. Over time, tanks, pipework and associated components can collect sediment, scale, biofilm and other contamination, creating conditions where bacteria may grow.

Thomson Environmental Services provide professional cleaning and disinfecting services for commercial, residential and public buildings. Based at the Surrey Research Park, our experienced Water Quality Engineers help landlords, facilities managers, building owners and `the responsible person` keep their water systems safe, hygienic and compliant.

As experts in all things Legionella, we provide practical support where cleaning, disinfection or remedial action is needed following a risk assessment, monitoring visit, sampling result or system inspection.


When Cleaning & Disinfecting May Be Needed

Cleaning and disinfecting may be recommended when a water system shows signs of contamination, poor condition or increased Legionella risk. It may also be required after certain system changes or periods of low use.

This can include:

  • Cold water storage tank cleaning
  • Disinfection of tanks and pipework
  • Cleaning after unsatisfactory sample results
  • Cleaning following a Legionella risk assessment
  • Disinfection after plumbing alterations or remedial works
  • Support after periods of stagnation or reduced building use
  • Cleaning of water system components where hygiene has deteriorated

The aim is to help restore water hygiene, reduce risk and support the safe operation of your building.


Safe, Practical Water Hygiene Support

Our team carries out cleaning and disinfection work carefully, with clear attention to safety, access, building use and compliance requirements.

We will explain what needs to be done, why the work is required and how it should be managed. Once the work is complete, we can provide clear documentation for your records and advise on any follow-up monitoring or sampling that may be needed.


Part of a Wider Legionella Control Programme

Cleaning and disinfecting is often one part of a wider water hygiene strategy. It may sit alongside regular monitoring, water sampling, booster pump servicing and a current Legionella risk assessment.

Thomson Environmental Services can help you understand where cleaning and disinfecting fits within your overall compliance duties, so your water systems are not just cleaned, but properly managed going forward.
