Legionella Testing & Water Analysis

Legionella Control International offer a comprehensive suite of UKAS accredited laboratory tests including legionella testing, sampling and water analysis of environmental samples for the detection of legionella bacteria and other waterborne pathogens commonly found in man-made water systems.

Our specialist water quality analysis services have been developed to support and enhance the environmental risk management activities of our clients around the world.

The periodic sampling and testing of water sources for the presence of legionella bacteria is a valuable means of demonstrating that adequate control over a water system is being achieved.

Expert Legionella Testing & Water Quality Analysis

Our expert laboratory based legionella testing, water quality analysis and microbiology services operate to strict quality control and laboratory accreditation standards to ensure accuracy and reliability.

legionella testingWe are members of the Legionella Control Association (LCA) and are formally accredited by them to deliver a number of  specialist legionella control related services including legionella testing and the analysis of water samples for legionella bacteria.

Jargon-Free Interpretation

Unlike other laboratory testing services which simply present clients with the results of each test without interpretation, we are experts in the control of Legionnaires' disease and legionella bacteria. This means that we can explain in jargon-free language what the results of individual tests mean for you, your risk management activities, and how to resolve any problems that are identified in an effective and timely manner.

Adequate Water System Control

The periodic sampling and testing of water sources from man-made sysyems for the presence of legionella bacteria is a valuable means of demonstrating that adequate control over such a water system is being achieved.

Additionally, the analysis of samples from water sources suspected of being contaminated with legionella bacteria is also an important forensic tool that can be used to identify possible sources of risk within a water system.

Regular Monitoring & Routine Inspection

The UK's Health & Safety Executive (HSE) in their Approved Code of Practice (ACOP) L8, "Legionnaires' disease. The control of legionella bacteria in water systems" state that:

“ … Periodic sampling and testing for the presence of legionella bacteria may also be relevant to show that adequate control is being achieved. However, reliably detecting the presence of legionella bacteria is technically difficult and requires specialist laboratory facilities.”

Paragraph 68. HSE "ACOP L8".

Serogroup Identification

Qualified microbiological laboratories are experienced in the detection of legionella bacteria and, using specialist techniques they are able to identify specific serogroups in individual samples.

How Long Does Laboratory Testing Take?

Laboratory based testing and analysis procedures are typically performed using a standard culture procedure which usually takes between 10 and 12 days to complete. However, if our analysis indicates a potential positive result for the presence of legionella bacteria earlier than this you will be notified immediately and the implications of the preliminary results explained in detail.

Get Accurate Yes:No Results in Only 25 Minutes

If time is of the essence and accurate results are required urgently then we also offer an innovative rapid self-test (LegionellaFast) which uses the latest “rapid-test” technology to detect Legionella bacteria in water.

LegionellaFast is quick and simple to use and will deliver very accurate, easy to understand YES::NO test results on-site in only 25 minutes... more here
