Water Sampling Services
BioSweep UK provides professional water sampling services for Legionella, Pseudomonas, total viable counts (TVC), E. coli and coliform bacteria across domestic, commercial and managed water systems.
Our trained technicians collect samples using established procedures, with microbiological analysis undertaken by independent laboratories using UKAS-accredited methods where applicable.
Water sampling can support Legionella risk assessments, water hygiene monitoring, contamination investigations and verification following appropriate remedial works. Sampling programmes are tailored to the water system, identified risks and information required.
Our Water Sampling Services
BioSweep UK provides professional water sample collection for a range of microbiological investigations. Samples are submitted to independent laboratories for analysis using appropriate methods.
Legionella Sampling
Water samples are collected from selected points within hot and cold water systems to investigate the presence of Legionella bacteria. Sampling may be recommended following a risk assessment, where control measures are ineffective, or as part of an established monitoring programme
.
Total Viable Count (TVC) Sampling
TVC testing measures the number of viable microorganisms capable of growing under specified laboratory conditions, commonly at 22°C and 37°C. Results can help identify changes in general microbiological water quality and support investigation of water system hygiene. TVC results alone do not establish whether water is safe.
E. coli Sampling
Testing for Escherichia coli (E. coli) helps identify potential faecal contamination within water supplies. Detection may indicate a significant water quality concern requiring investigation and appropriate action.
Pseudomonas Sampling
Water sampling for Pseudomonas aeruginosa helps assess potential contamination within water systems, particularly in healthcare, care and other higher-risk environments. Testing may be appropriate where vulnerable individuals could be exposed or where water hygiene concerns have been identified.
Total Coliform Sampling
Total coliform testing helps assess microbiological water quality and may indicate contamination or problems within a water supply or distribution system. Results should be interpreted alongside the type of water system, sampling location and other relevant microbiological findings.
All sampling is undertaken according to the investigation requirements, with laboratory findings reported alongside relevant guidance or reference criteria where applicable.
How BioSweep Supports Water Hygiene Management
Professional water sampling provides valuable microbiological information to support water hygiene investigations, risk assessments and ongoing management programmes.
BioSweep UK's services can include:
Sampling Programme Planning: Identifying appropriate sampling locations and microbiological tests according to the water system, identified risks and investigation objectives.
Professional Sample Collection: Collecting water samples using established procedures, with appropriate handling and transportation to independent laboratories.
Independent Laboratory Analysis: Microbiological testing for selected organisms and indicators, using UKAS-accredited laboratory methods where applicable.
Results & Reporting: Providing laboratory findings with relevant interpretation and guidance to help clients understand the results.
Follow-Up Recommendations: Advising where further investigation, additional sampling or specialist remedial action may be appropriate.
Water sampling may be undertaken alongside a Legionella risk assessment, following changes to a water system, or where monitoring and other findings indicate that microbiological investigation is necessary.
Sampling provides information about the conditions at the time and locations tested. It does not replace appropriate system maintenance, monitoring or other control measures.
Authoritative Guidance
Water sampling and microbiological analysis can support the investigation and management of water hygiene risks. The following official resources provide guidance on Legionella control, water system management and drinking water quality.
HSE ACoP L8 – Legionnaires' Disease
The Health and Safety Executive's Approved Code of Practice outlines the responsibilities of dutyholders for assessing and controlling Legionella risks.
HSG274 – Legionnaires' Disease: Technical Guidance
Provides detailed guidance on managing Legionella risks within hot and cold water systems and other relevant installations, including circumstances where microbiological sampling may be appropriate.
Drinking Water Inspectorate (DWI)
Provides information on drinking water quality, regulatory standards and microbiological parameters, including E. coli and coliform bacteria.
HSE Approved Code of Practice L8 – Legionella control in water systems

Related Water Hygiene Services
Microbiological water sampling and Legionella risk assessments are complementary services that support effective water hygiene management.
A Legionella risk assessment identifies potential hazards within a water system and recommends appropriate control measures. Water sampling provides microbiological data to support investigations, monitoring and assessment of those measures where required.
BioSweep UK offers both services, helping landlords, businesses and dutyholders make informed decisions about their water hygiene responsibilities.
Water sampling may be carried out alongside a Legionella Risk Assessment where appropriate, providing microbiological data to support water hygiene assessment and ongoing risk management.
Where contamination is identified, remediation may involve broader Decontamination Services depending on findings.
