Sampling

Water sampling is an important part of checking water quality and managing Legionella risk. It helps identify whether bacteria are present in a water system and whether further action may be needed to keep the building safe.

Thomson Environmental Services provides professional water sampling for commercial, residential and public buildings. Based at the Surrey Research Park, our experienced Water Quality Engineers carry out sampling as part of Legionella control, water hygiene monitoring and wider compliance support.

As experts in all things Legionella, we help clients understand when sampling is needed, what the results mean and what steps should be taken next.

When Water Sampling May Be Needed

Sampling is not always required for every building, but it can be an important part of a water hygiene programme, especially where there is an increased level of risk or concern.

Water sampling may be recommended:

  • As part of an ongoing monitoring contract
  • Following a Legionella risk assessment
  • After cleaning and disinfecting work
  • Where water temperatures are not being properly controlled
  • Following changes to the water system
  • After periods of low use or stagnation
  • Where previous results have raised concerns
  • In higher-risk environments or more complex buildings

The purpose is to provide clear evidence about the condition of the water system and support informed decisions.

Clear Results and Practical Guidance

Taking a sample is only one part of the process. It is also important that results are properly understood and acted on where necessary.

Thomson Environmental Services can arrange appropriate sampling, provide clear reporting and explain what the findings mean for your building. If further action is required, we can advise on practical next steps, which may include further monitoring, cleaning and disinfection, system checks or remedial works.

Part of Effective Legionella Control

Sampling works best when it forms part of a wider water hygiene strategy. It should be supported by a current Legionella risk assessment, regular monitoring, accurate records and appropriate control measures.

Our team can help you put these pieces together, giving you a more complete view of your water system and helping you manage your responsibilities with confidence.
