Why can’t we post the sample back to you, couriers must add to the cost of your product.



Laboratories are regularly audited to ensure they meet UKAS standards.  Samples must be marked with the time/date that they were taken and analysis must begin within 48 hours (max). The UK postal service is no longer guaranteed to deliver within this time period. Samples that arrive at the laboratory more than 48 hours after sampling are deemed Non-Compliant and should not be tested.



Wouldn’t it be easier to use smaller bottles, other companies just ask for 250ml but AquaCert send out 1 litre bottles.



Yes, it would be a lot easier!

However, the international standard for legionella testing is set out in the document BS EN ISO 11731:2017 Water quality - Enumeration of Legionella.

We don’t take shortcuts, our testing is 100% UKAS accredited and the results will hold up in court.

Taking smaller sample sizes or allowing more than 48 hours transit time is not recommended and the validity of the result  would be challenged if used as evidence in a law court.
