Water Testing London

Water Testing London


Testing for Legionella bacteria is crucial for water safety, especially in a bustling city like London. Metro PAT specializes in comprehensive water testing services across London to help businesses and residential properties comply with health and safety regulations.


Why Water Testing is Essential in London


London's diverse buildings, from historic to modern complexes, often have intricate water systems. If not properly monitored and maintained, these systems can be breeding grounds for Legionella bacteria. Regular water testing ensures occupants' safety and prevents potential outbreaks of Legionnaires' disease.


Comprehensive Legionella Testing Services


At Metro PAT, we offer specialized legionella testing services that include:


Temperature Monitoring


Temperature is a critical factor in controlling the growth of Legionella bacteria. We measure the temperature of water systems to ensure they fall within safe ranges. This helps identify potential risks and take corrective measures promptly.


Water System Inspections


Our team thoroughly inspects your water systems, including tanks, pipes, and outlets. We look for any signs of stagnation, corrosion, or biofilm formation that could contribute to Legionella's growth.


Detailed Reporting and Recommendations


After testing, we provide detailed reports that outline our findings. Our reports include actionable recommendations to improve your water system's safety and compliance. We aim to help you create a safer environment for everyone who uses your facilities.


Compliance with Health and Safety Regulations


Our services are designed to help you meet all relevant health and safety regulations, including the Health and Safety Executive’s (HSE) Approved Code of Practice (ACOP) L8 guidelines. By partnering with Metro PAT, you can be confident that your water systems are managed effectively and safely.

Legionella Testing FAQs


1. What Legionella testing services does Metro PAT offer?


Metro PAT offers a range of UKAS-accredited Legionella testing, analysis, and sampling services. These include specialist Legionella swabs, water sample collection (250ml, 500ml, and 1 litre), standard filtration, and centrifugal separation methods.


2. Is Legionella testing a legal requirement for domestic water systems?


No, if they are well-managed, Legionella testing is not a legal requirement for standard domestic hot and cold water systems. However, cooling towers must be tested at least quarterly, with more frequent testing when newly commissioned or if results indicate a need.


3. What is the difference between Legionella testing and Legionella sampling?


  • Legionella Testing: This involves the microbial examination of a water sample in a laboratory to identify the presence or absence of Legionella.

  • Legionella Sampling: This refers to collecting the water sample, including the strategy and methodology used for sample collection.


4. Why should I choose Metro PAT for Legionella testing services?


Metro PAT has extensive experience and expertise in Legionella sampling, testing, and analysis. They work with a network of independent UKAS accredited laboratories to provide tailored services and ensure reliable results.


5. Can Metro PAT provide rapid Legionella test results?


Metro PAT can offer a UKAS-accredited Legionella Assay Test that provides results within 48 hours for urgent situations, such as outbreaks or high-risk environments.


6. How often should cooling towers be tested for Legionella?


Cooling towers should be tested monthly when newly commissioned and at least quarterly during regular operation. In some cases, weekly testing may be necessary if results indicate a potential risk.


7. What information must I provide when booking a Legionella testing service with Metro PAT?


When booking a Legionella testing service, please provide the following information:

  • The systems you wish to be tested

  • The number of tests required

  • The location of the site(s) to be tested

  • Any access issues or precautions needed for sample collection

  • The reason for sampling


8. Do I need a Legionella risk assessment before starting a testing program?


Yes, a Legionella risk assessment is the legal requirement from which your testing program should start. Testing without a suitable risk assessment or control scheme will not offer adequate protection.


9. Are onsite Legionella tests reliable?


Onsite Legionella tests are not UKAS accredited and cannot be used as definitive confirmation of Legionella's presence. While they may provide a quick indication of potential risk, they are not considered reliable for reducing liabilities or risks.


10. How long does it take to receive Legionella test results using the standard culture method?


It typically takes between 10 and 12 days to receive Legionella test results using the standard culture method, as the organism needs time to grow on the inoculated plate.


11. What British Standards are associated with Legionella testing and analysis?


The principal British Standards associated with Legionella testing and analysis include:

  • BS EN ISO 11731:1998, BS 6068-4.12:1998

  • BS EN ISO 11731-2:2008, BS6068-4, 18:2004


12. Does Metro PAT provide original UKAS certificates with test results?


Metro PAT ensures that all results are provided with original UKAS certificates to maintain transparency and compliance with British Standards and HSE guidelines.
