Water Sampling Services
Accurate water sampling with independent UKAS‑accredited laboratory testing
BioSweep® UK provides professional water sampling services using independent UKAS‑accredited laboratories to deliver accurate, reliable, and evidence‑backed results. Our testing helps assess microbial contamination, water safety, and system hygiene in domestic and non‑domestic water systems, supporting duty holders with compliance, risk management, and occupant safety across residential, commercial, and managed facilities.
Our Water Sampling Services
BioSweep® UK offers a comprehensive range of water sampling diagnostics, including:
Legionella Sampling
We collect water samples for Legionella analysis at high-risk points in the system, following best-practice methods such as pre-flushing or post-flushing as recommended by BS7592. Independent UKAS-accredited laboratories then culture and analyse the samples. While routine sampling is not always required for domestic systems, it is an important diagnostic tool for high-risk sources or where temperature monitoring indicates a potential problem.
Total Viable Count (TVC)
TVC sampling estimates the total number of living microorganisms in water systems, providing a general indicator of microbial contamination and hygiene. High TVC results may indicate poor control or system contamination, while low counts demonstrate effective microbial management.
E. coli Sampling
Sampling for E. coli identifies potential faecal contamination in private wells, pools, or drinking water. Positive results indicate the presence of harmful pathogens, requiring investigation, remediation, and re-sampling.
Pseudomonas Sampling
We collect samples to detect opportunistic pathogens such as Pseudomonas aeruginosa, particularly relevant in hospitals, care homes, and hot tubs. Positive results generally require immediate action, including system flushing, disinfection, or temporary restriction of affected outlets.
Total Coliform Sampling
Total coliform testing provides a general measure of water system hygiene, highlighting potential contamination from sewage, surface water, or other sources. Faecal coliforms, especially E. coli, are the most accurate indicators of human or animal waste contamination.
How BioSweep® Supports Compliance
Our water sampling services complement Legionella risk assessments, helping duty holders comply with ACOP L8 and HSG274 guidance. Key elements include:
System Assessment: Identifying potential risk points such as tanks, cylinders, and sentinel outlets.
Temperature Checks: Monitoring hot and cold water to ensure temperatures meet HSE recommendations.
Sample Collection: Professional, sterile sampling at critical points in the water system.
Reporting Support: Independent laboratory results guide cleaning, disinfection, or system modifications to maintain compliance.
Sampling is typically required when systems are high-risk, after modifications, or when monitoring indicates potential issues. BioSweep® UK ensures collection is performed safely, efficiently, and in line with regulatory best practice.
