Is your water contaminated with legionella?
Our laboratory tests can quickly and accurately identify whether your water systems meet the water quality standards set by the Health & Safety Executive for the permitted levels of Legionella bacteria in water.
Delivered through our network of independent UKAS accredited laboratories we are able to offer specialist legionella detection and analysis services.
Our specialists can accurately verify whether your water systems are contaminated with dangerous levels of Legionella bacteria, the bacterium responsible for the potentially fatal condition called Legionnaires’ disease.
Why should you test for legionella?
The Health & Safety Executive recommend that periodic water samples should be taken and tested for the presence of legionella to ensure bacteria counts are maintained within acceptable limits and adequate control over the water system is being achieved.
The frequency of testing should reflect the type of water system, the level of risk, and the specific recommendations identified in the Legionella risk assessment.
Legionella testing for hot & cold water systems
The Health & Safety Executive in their ACOP L8 and guidance document HSG274 Part 2 do not normally require domestic hot and cold water systems to be tested for legionella if they are well managed and are under adequate control.
However, testing of domestic hot and cold water is recommended under the following circumstances:
Testing cooling towers for legionella
The HSE call for cooling towers to be routinely tested for legionella at least every three months.
However, more frequent legionella testing of cooling towers is recommended under the following circumstances:
Water sampling & UKAS legionella testing services

How long does legionella testing take?
Typically, legionella testing in one of our laboratories will use a standard culture method which usually takes between 10 and 12 days to complete and return a result. However, sometimes our tests can indicate a potential legionella positive result earlier than the normal 10 to 12 days. If this happens then customers would be notified immediately and the results and their implications explained in detail.
Legionella testing standards
The main British Standards relevant to the detection of legionella and sampling methods include:
BS 7592:2008
This is a British Standard code of practice and deals with sampling for Legionella bacteria in water systems.
BS EN ISO 11731-2:2017
This British Standard deals with water quality, and in particular, the enumeration of Legionella.
