The microbiological analysis of water is an important tool in the management of water quality within differing water systems. It can highlight the presence of certain pathogenic microorganisms, and also provide evidence of deteriorating water quality over time.
The laboratory offers the following ISO 17025 UKAS accredited microbiological water analyses, based on the SCA Microbiology of Drinking Water (MoDW) standards for drinking/potable, recreational, surface and process waters as detailed below:
For our NHS clients requiring Endoscope rinse water analysis, we are also ISO 17025 UKAS accredited for Total Aerobic Colony Counts based on our in-house method using membrane filtration onto TSA based on HTM 2030 (withdrawn), section 9.223.
Customer Certificates of Analysis in PDF form are reported as soon as analyses are complete. These detail client and sample information with associated sample results.
A separate ‘Failing Result Notification’ will be sent to clients where samples have provided a failing result in relation to applicable legislative limits and guidance as specified within client contracts.
The Laboratory provides its customers with all appropriate sampling containers. Volumes of sampled water required are detailed within client contracts.

Monitoring for the presence of Legionella bacteria in a water system can greatly assist in the control of risk from that system. The Health & Safety Commission, Approved Code of Practice (commonly known as L8), specifies that samples for Legionella analysis should be sent to a UKAS accredited laboratory.
The Laboratory holds Legionella Control Association membership for Legionella Monitoring Services, 7.3 Laboratory Analysis.
Our ISO 17025 UKAS accredited methods are based on BS EN ISO 11731:2017: Water quality — Enumeration of Legionella. We can accept drinking/potable, recreational, surface and process waters.
The Laboratory partakes in the United Kingdom Health Security Agency (UKHSA) external interlaboratory legionella testing proficiency scheme, with a 100% pass rate to date.
Following concentration of legionella bacteria, and incubation on selective growth media, presumptive positive colonies are confirmed by serological testing as either L. pneumophila Sero-group 1, L. pneumophila Sero-groups 2-14 or Legionella species.
Customer Certificates of Analysis in PDF form are reported as soon as analyses are complete. These detail client and sample information with associated sample results.
A separate ‘Failing Result Notification’ will be sent to clients where samples have provided a failing result, typically after a day 3, 6 and 10 reads. Failing results are in relation to applicable legislative limits and guidance as specified within client contracts.
The Laboratory provides its customers with all appropriate sampling containers. Volumes of sampled water required are detailed within client contracts.

The microbiological monitoring of air and surface is a good indicator of the quality of air in the built environment. Air samples can be taken either actively or passively and surfaces can be sampled by contact plates or swabs.
The Laboratory holds ISO 17025 UKAS accreditation for the enumeration of aerobic bacteria and moulds (fungi) based on its in-house method using TSA and SDA agar growth media, incubated under temperature controlled conditions.
The Laboratory can also offer non-accredited dip-slide analysis, dust filter weighs and bacterial / fungal swab testing.
Consumables (contact plates and swabs) can be provided upon request.
In partnership with our in-house Technical Consultancy team of engineers, the Laboratory can help provide a one-stop service for air quality testing – from initial aseptic air sampling, to laboratory analysis and test reports.
