Since starting over 40 years ago water testing is key to our success – whether testing for the chemistry of water to enable bespoke filtration or bacteria content for safe water management.

We use a nationwide network of laboratories which are accredited by the United Kingdom Accreditation Service (UKAS)

Typical testing;

– Drinking Water Analysis
– Legionella
– Borehole Analysis
– Closed System Heating and Cooling Circuits
– Cooling Tower System
– General Bacteria Water Analysis
– Ultra-Pure Water Analysis
– Hospital Systems including Pseudomonas
– And many many more……


How long does a Legionella test take?

A full Legionella test using culture method in a UKAS lab can take up to 14 day.

Lubron can offer a new, reliable and rapid Legionella test. The test, known as qPCR, detects and counts DNA from all Legionella species in potable water samples. Wherever Legionella is present, Legionella genetic material will also be present, sometimes inside whole cells, but also free floating in the water.

qPCR (or Quantitative Polymerase Chain Reaction to give the test its full title), identifies and repeatedly copies all the Legionella DNA in the water sample.

What does TVC stand for?

Total viable count (TVC) is a test that estimates the total numbers of microorganisms, such as bacteria, yeast or mould species, that are present in a water sample. TVC may also be expressed as aerobic colony count.

The results of a TVC test offer an indication into the general level of contamination within a system and the overall quality of the water.

What is a Dipslide?

The definition of a dipslide, as described in the HSE approved code of practice and guidance for the control of legionella bacteria in water systems is a means of testing the microbial content of liquids. It consists of a plastic carrier bearing a sterile culture medium which can be dipped in the liquid to be sampled. It is then incubated to allow microbial growth. The resulting microbial colonies are estimated by reference to a chart.

When should I test for Legionella?

Refer to HSG274 Part 2, page 40 onwards.
Legionella testing is recommended when:
1. A water system is being treated with biocides and water is stored or distributed at low temperatures
2. There is a lack of confidence in the water system integrity and degree of water quality control
3. In accordance with the Water Hygiene Risk Assessment, if temperature control and disinfectant concentrations are sporadic and not being consistently achieved. Once the water system is brought back under control to establish and demonstrate a satisfactory ‘baseline’ in accordance with ACoP L8.
4. There is a high risk population or critical exposure (eg hospital, healthcare premises, clinical or laboratory usage, swimming or spa pool usage, care home setting as well as public or commercial duty of care – HM Prison, public buildings, commercial offices, private landlord properties and so on).
Property owners or managers are also required to test for Legionella across both hot and cold water systems, in systems where dead legs occur, sites containing cold water storage systems and cooling towers.

Do you have to use an accredited lab?

HSG274 Guidance states that testing should be carried out under the United Kingdom Accreditation Service (UKAS) to the norm ISO/IEC 17025:2005.
Analysis of water samples for Legionella should be performed in UKAS accredited laboratories with the current ISO standard methods for the detection and enumeration of legionella included within the scope of
accreditation. These laboratories should also take part in a water microbiology proficiency testing scheme (such as that run by PHE or an equivalent scheme accredited to ISO 17043:2010). Alternative quantitative testing methods may be used as long as they have been validated using ISO 17994:2004 and meet the required sensitivity and specificity.
