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. 


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 unless otherwise stated.  Once testing is complete you are issued with a test certificate and any recommended actions that may be required.

Same Day Testing with a result in about an hour.

Common Questions & Answers


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?  Yes you do.  Testing water for Legionella without a risk assessment can still leave you liable.


Are We Competent?  To carry out our water testing we use a UKAS accredited laboratory.  UKAS is recognised by governments to assess against internationally agreed standards for organisations that provide certification, testing, inspection and calibration services.


Can You Use On Site Dip Slides/Swabs?  Dip slides & swabs are very usful but on site tests are not accredited and they only really give an indication of bacterial presence and any positive result would need a further sample to be taken. 


How Much Does Legionella Testing Cost?  Our minimum test fee is £75.00 which covers the first three samples taken for testing (this does not include same day testing or PCR analysis).  Each additional sample will cost £25.00.  Same day tests cost £75.00 per sample.  PCR Analysis is from £300.00 per sample.  Additional costs may apply such as travel.  Email us for a quote.
