UKAS‑Accredited Water Sampling & Analysis
Legionella, TVC, E. coli, Coliforms, Pseudomonas—and more. Nationwide sampling with ISO/IEC 17025 laboratory analysis.
Protect your people, prove compliance, and act fast with clear, audit‑ready results and expert interpretation.
Why choose us?
- UKAS‑accredited laboratories (ISO/IEC 17025): All microbiological analysis performed through accredited labs for dependable, defensible results.
- Trained samplers nationwide: Routine monitoring and rapid-response sampling anywhere in the UK.
- End‑to‑end service: Sampling, chilled transport, analysis, interpretation, and corrective‑action guidance.
- Clear reporting: Easy‑to‑read certificates with traffic‑light flags, action recommendations, and trend views.
- Compliance, simplified: Reporting aligned to ACoP L8, HSG 274, and Drinking Water Inspectorate (DWI) guidance where applicable.
What we test
- Legionella spp. (including Legionella pneumophila and serogroup 1 where required)
- Total Viable Count (TVC) at relevant temperatures (e.g., 22–30°C / 36–37°C)
- E. coli and Total Coliforms
- Pseudomonas aeruginosa
- Enterococci (faecal streptococci)
- Clostridium perfringens (including spores, where required)
- Heterotrophic Plate Count (HPC) and biofilm indicators
- Physico‑chemical screens on request (pH, conductivity, metals, nutrients, oxidant residuals)
Sample types: potable water (drinking outlets), H&C systems, showers and TMVs, cold water storage tanks (CWST), calorifiers, cooling towers/evaporative condensers, closed heating/chilled systems, ice machines, dental units, leisure water (pools/spas) and more.
Methods and Standards
- UKAS‑accredited methods for culture and confirmation (ISO/BS EN methods as applicable).
- Sterile sampling using pre‑prepared bottle kits and appropriate neutralisers (e.g., sodium thiosulfate for chlorinated water).
- Chilled chain of custody: Insulated packaging and same‑day/next‑day courier to maintain sample integrity within method holding times.
Turnaround Times (TAT)
- Priority same‑day collection available in most regions.
- Standard: Results typically available within 3–10 working days depending on organism (e.g., Legionella culture requires longer incubation).
- Rapid screens and qPCR options available on request for investigation support.
Need urgent public‑health support? Ask about accelerated logistics and interim advisories while culture tests incubate.

Reporting you can act on
- Certificate of Analysis with organism counts/absence, detection limits, and method references.
- Traffic‑light status against typical guidance thresholds where relevant.
- Root‑cause pointers and next steps (flushing, temperature correction, disinfection, remedial works).
- Trend reports for routine monitoring programmes.
Frequently Asked Questions
Are you UKAS accredited? All microbiological analysis is performed through UKAS‑accredited laboratories (ISO/IEC 17025). Certificates reference the method numbers and accreditation scope.
How quickly can you attend? Often same or next working day depending on location and urgency.
What if we get a positive result? We provide a clear action plan—flushing, temperature restoration, secondary disinfection, or targeted remedial works—and can organise follow‑up sampling to confirm clearance.
Can you manage regular monitoring? Yes—monthly/quarterly/annual programmes with fixed pricing and trend reporting.

Sectors we support
Student accommodation, healthcare, education, leisure & hospitality, commercial offices, manufacturing, public sector estates, housing providers, and more.

Compliance Alignment
Our reports are structured to support obligations under ACoP L8 and HSG 274, as well as DWI guidance for drinking water quality where applicable, and relevant British/ISO standards referenced by the laboratory methods.
