As well as having a Legionella Risk Assessment in place you may 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.
All our water samples (except for same day testing) are tested by a UKAS accredited laboratory as required by the HSE ACOP L8. Our normal turnaround time for test results is on average 14 days. Once testing is complete you are issued with a test report.
Why Does Testing Take So Long? The HSE ACOP L8 requires all water samples to be tested by a UKAS accredited laboratory who grow and count the bacteria over a period of 2 weeks. At the momment this is the most reliable way to test for all groups of Legionella bacteria and give a true picture of any issue.
Same Day Testing, We do offer a same day testing service but in comparison to the UKAS accredted test the results of same day testing are limited and are not UKAS accredited and so do not meet the requirements of the ACOP L8. The same day test can be completed in less than an hour but only tests for the most common type of Legionella bacteria. The major benefit of the same day test is that it can give an immediate indication of the presence of the most commom group of Legionella bacteria.
If either the UKAS accredited test or the same day test shows a positive result we always recommend further action followed by further testing until a negative test result is achieved.
Same Day Testing
If test results are positive a full UKAS accredited test should be carried out to fully assess the risk.
UKAS Accredited Testing
If results are positive further testing needs to be carried out and steps put in place to reduce bacteria levels.
Do I Need My Water Testing? You may not need to have your water tested at all depending on the outcome of the risk assessment. We do however advise you to have your water tested to fully assess any risk.
Do I Need an Assessment Before Testing My Water? Yes you do. Testing water for Legionella without a risk assessment can still leave you liable.
Are We Competent? As a Duty Holder or person in charge of premises it is your responsibility to ensure anyone who undertakes work in your property is competent to do so. Our Water Wise engineers are City & Guilds accredited. We are one of only a handful of companies in the UK to receive the Government Endorsed Trust Mark for our Legionella work.
To carry out our water testing we use a UKAS accredited laboratory. The United Kingdom Accreditation Service (UKAS) is the sole national accreditation body for the United Kingdom. UKAS is recognised by government, to assess against internationally agreed standards, organisations that provide certification, testing, inspection and calibration services.
How Much Does Legionella Testing Cost? Our minimum test fee is £75.00 which covers the first three UKAS samples taken for testing. Each additional UKAS sample will cost £25.00. All same day tests cost £75.00. Additional costs may apply such as travel.
