Reliable legionella testing services to safeguard water quality and compliance

At Marlowe Environmental Services, we provide expert legionella testing services tailored to your industry’s needs. Using UKAS-accredited laboratories, we deliver fast, accurate results to help you take proactive action before issues arise. We follow official guidance and involve your water safety group in developing targeted sampling strategies to ensure best practice.

Testing for legionella is undertaken as part of a structured approach and in line with recommended measures, ensuring sampling is purposeful and effective. Whether you manage office buildings, hospitals, hotels, or manufacturing plants, our solutions ensure you meet all compliance and safety standards.

Building owners have a legal responsibility to carry out legionella risk assessments and routine testing to comply with health and safety legislation, including the Health and Safety at Work Act.

Compliance with ACoP L8, HSG274, and HTM 04-01 guidelines is essential to meeting legal requirements and maintaining a safe, operational water system. Legionella risk assessment and prevention measures are vital to reduce exposure and the risk of disease in building water systems.

Legionella bacteria are classified as substances hazardous to health, and regular testing helps control exposure to these substances in building water systems. A risk assessment is used to determine when and where legionella sampling should be undertaken, and sampling is only necessary when control measures indicate a need.

What is legionella testing?

Legionella testing is a vital process for detecting harmful Legionella bacteria in water systems before they pose a serious health risk. Testing can identify multiple species of Legionella organisms, including those most commonly associated with disease.

Representative sample collection from appropriate locations is essential for accurate detection of legionella bacteria. Environmental sampling, including the collection of water samples from various outlets, is carried out to assess the presence of legionella and other waterborne pathogens, with accredited laboratory analysis being crucial for reliable results.

Regular legionella testing is essential for commercial, industrial, and healthcare environments to prevent waterborne risks and legal non-compliance. When interpreting test results, several pieces of information, including water treatment history and test results, are used to assess water quality and system safety.

Water Sampling

Collecting samples from key points in the water system.

Laboratory Analysis

Testing the samples in a UKAS-accredited laboratory to detect Legionella bacteria.

Detailed Reporting

Providing comprehensive results and expert guidance on any necessary actions to maintain compliance.

It is important to avoid contamination during collection, protecting the integrity of the water system and ensuring sample validity. Water samples should be collected in sterile bottles from outlets such as showers, hot tubs, cold water supplies, as well as from plumbing systems, to ensure accurate results.

Sampling may be advised in specific circumstances, such as suspected contamination, outbreak investigation, or when routine samples indicate a problem. Following current procedures, guidance, and advice from health protection teams, and maintaining the chain of custody for samples, is critical for effective investigation and response.
