There is no automatic requirement to test for Legionella. The need for testing should be identified during the risk assessment process or during routine control and prevention measures. This is stated in the HSE's ACOP L8, HSG 274 part 2, section 2.120 and section 10 of the Department of Health's HTM 04-01 part B. Where a need to carry out Legionella Testing has been identified it should be done using as UKAS accredited method.
Our Legionella Testing Service
To ensure compliance with the HSE's ACOP L8 and the Department of Health's HTM 04-01 we will only carry out any testing when there is a valid and indate Legionella risk assessment in place.
We offer rapid onsite and UKAS accredited laboratory testing. A positive onsite test result requires a follow up test using a UKAS accredited laboratory test.
Do You Use/Supply Dip Slides? The ACOP L8 identifies the use of dip slides for aerobic bacteria only and not for hot and cold water systems. HTM 01-05 issued by the Department of Health states in section 6.78 "Apart from situations where there are indications from taste or odour, microbiological monitoring using dip slides for TVC's is not considered essential. HTM 01-05 section 19.68 and HTM 04-01 part B section 9.3 states "All microbiological measurements should be by approved methods and/or be carried out by UKAS accredited laboratories. Dip slides are not acceptable." So no, we do not use dip slides as they are not UKAS accredited and have a very limited use when testing for Legionella in water systems.
