Comprehensive potable water testing
Potable water testing
Our comprehensive testing for potable water ensures the safety and quality of your drinking water. Specialising in both microbiological and chemical analysis, we provide accurate, reliable, UKAS-accredited results that meet regulatory standards.
From Legionella and E. coli testing to detecting harmful chemicals like lead and copper, we investigate concerns regarding new domestic water supply installation, new connection to mains, routine microbiological assessment and drinking water complaints.

Microbiological testing
We provide the following services for potable waters:
We test for total coliform bacteria, which are indicators of potential contamination in your water.
This bacterium can signal contamination by faecal matter, and its presence is a serious health concern.
This opportunistic pathogen can thrive in drinking water systems and cause infections, especially in individuals with compromised immune systems.
Legionella bacteria can cause serious respiratory infections such as Legionnaires' disease. We offer accredited tests to identify Legionella in your water supply.
Chemical testing
We test for a range of chemical contaminants in potable water, including metals (such as lead and copper), pesticides, and other potentially harmful substances. Our tests help you ensure that your water meets UK and European regulations.
Water quality concerns
If you have concerns about the taste, odour, or appearance of your drinking water, we can investigate the root causes. Issues like discolouration, bad smells, or poor taste are often linked to deteriorating internal plumbing systems. These problems may arise from poor maintenance, incorrect use of materials, stagnation, or insufficient storage conditions, all of which can create an environment for microorganisms to proliferate.
Healthcare potable water testing
Pipework supplying potable water within healthcare premises is often large and complex, and comprehensive management of the system is necessary to control waterborne pathogens. As well as compliance with the HSE’s Approved Code of Practice and guidance on regulations ‘Legionnaires’ disease: The control of Legionella bacteria in water systems (L8)’, particular significance is placed within HTM 04-01 on the control of Pseudomonas aeruginosa in augmented care units.
Pseudomonas aeruginosa
Pseudomonas aeruginosa is an opportunistic pathogen capable of infecting vulnerable patients and has been shown to readily colonise systems and outlets without proper management and surveillance.
We offer two UKAS-accredited methods available for the detection of Pseudomonas aeruginosa. One is the culture method as specified in HTM 04-01 Part B Appendix F and based on ‘Microbiology of drinking water – Part 8: the isolation and enumeration of Aeromonas and Pseudomonas aeruginosa’.
In the second method, results are available after 24 hours as a confirmed positive. The method has been validated following BS EN ISO 17994 and shown to have comparable sensitivity and specificity to the culture test. This test is based on the ‘Microbiology of drinking water – Part 8: the isolation and enumeration of Aeromonas and Pseudomonas aeruginosa’ Method C.
Retention of positive isolates can be arranged upon request and ranges can be adjusted as required with suitable dilutions.
