As well as having a Legionella Risk Assessment in place you may also have a requirement to carry out Legionella Testing.  We recommend that Legionella Testing be carried out as part of the initial Risk Assessment and then annually thereafter if a need for testing has been identified.  More regular testing may be advisable depending on the building usage or the outcome of the risk assessment.


Testing for Legionella is not an automatic requirement and should only be carried out after a Legionella Risk Assessment identifies a need for testing.  In environments that present an increased level of risk or where more susceptible groups are present such as in a care home then regular Legionella testing should be carried out.


All water samples should be tested by a UKAS accredited laboratory as required by the HSE ACOP L8.  At Water Wise we have a testing contract with one of the country’s biggest and leading UKAS accredited testing laboratories.


We offer several types of Legionella testing as well as Microbiological Analysis which looks for other types of bacteria such as coliforms or e.coli bacteria.  These bacteria can on their own cause serious illness and are often called "indicator bacteria" as they reflect the state of the water quality.


Our normal turnaround time for test results is on average 14 days unless otherwise stated.  Once testing is complete you are issued with a test certificate and any recommended actions that may be required.  If any test reflects a positive result for bacteria further action followed by further testing will be required until test results show that the bacteria is eliminated or falls within controllable levels.


Please note this is not a "mail order" service.  Our service involves one of our engineers calling to the site to take the water samples which are then delivered to a UKAS accredited testing service.
