Water testing, analysis, sampling
uRisk provides water testing, analysis and sampling for a wide range of bacterias from all ranges of water systems including: drinking water, hot and cold domestic supply, cold water storage tanks, swimming pools and spa’s, closed systems, lakes and reservoirs and anywhere else there is water.
Water testing, analysis, sampling strategy
Water testing appears to be a simple process of filling a sample bottle, but it can become extremely problematic as the method and process of sample taking can have an important effect on the final sample results.
For instance, there are two types of sampling. Pre-flush and post-flush. A pre-flush is a sample taken before the tap is flushed, and a post-flush is a sample taken after the tap is flushed. Depending on how long the tap is run will determine how far into the system the sample is taken from. This is why all sampling should be undertaken in accordance with BS 7592 as a simple change in how the sample is taken can have a significant impact on the results.
Also, it is important not to mix samples from two taps into a single bottle. This will dilute any positive results. It is also more costly should you have a positive because you will need to take further water samples to identify where the bacteria is present.
The appropriate techniques must be used to ensure the validity of the sample results. These techniques may include:
- Appropriate use of PPE
- Sampler cleanliness
- Cross contamination
- Speed of delivery from time taken to delivery to laboratory

Why carry out routine water sampling?
Routine water sampling is the most effective way to determine water quality. Without water testing, analysis, sampling you are unable to identify water quality and therefore you are unable to determine whether your water management and legionella control is sufficient.
With periodic water testing you are able to demonstrate that your water management and legionella control procedures are suitable and the water in your water system is fit for purpose.
All our water samples are tested in UKAS accredited laboratories as standard. We are able to carry out tests on a wide range of microbiological samples and chemical testing services.
Flexible water sampling services
uRisk provides a range of water sampling services from DIY test kits to one off sampling services (where a trained engineer carries out the sampling) or a routine water sampling programme carried out by trained engineers.
All sampling visits are inclusive of full water system inspections, results explanation, recommendations and certification.
Water sampling bottles
Water sampling bottles are sterile bottles treated with sodium thiosulphate which aims to neutralise the effects of residual chlorine in the sample bottle. These UKAS approved bottles should also be collected in the appropriate containers. So you cannot use any old plastic bottle!
All samples should be labelled with the sample number, date, sample type, company name, sample location, sample system (hot or cold), water temperature. Chemical samples will also need to be taken using the appropriate bottles.
Water sampling competence
All water hygiene engineers have been trained to take samples in a manner that is least likely to contaminate the sample. Whilst it may appear to be obvious, there any many procedures to be followed during the sampling process. For instance, placing the bottle cap downwards can alter the sample results. It’s really that easy to create false readings!

Legionella Risk Assessment FAQs
When and how often do I need a risk assessment?
Under the Health and Safety at Work Act 1974 and in compliance with the Approved Code of Practice (ACoP L8, HSG 274), duty holders, including employers and those in control of premises, must ensure the health and safety of their employees or others who may be affected by their undertaking, this includes the risk of legionella. Legionnaires Disease is a form of pneumonia, which can be fatal and the main route of infection is through inhalation, by inhaling airborne water droplets that contain Legionella. This also applies if you are a private Landlord and have rental properties which are occupied.
This includes taking suitable precautions to prevent, manage and control the risk of exposure to legionella. You can do this by undertaking the following: a risk assessment, actioning all identified risks within the initial report with remedial works, sampling the water quality to confirm bacterial presence with water testing, and carrying out ongoing record keeping also known as monitoring.
Do I need testing, a risk assessment or both?
Legionella testing, water testing or sampling is not to be confused with a legionella risk assessment. You are required by law to undertake a legionella risk assessment under the Health and Safety at Work Act 1974, COSHH and a number of other regulations where you can show you are working to comply with the HSE's HSG 274 legionella guidelines.Testing or sampling whilst not a legal requirement on it's own, it plays an important role in determining how efficient a water system is managed. Your risk assessment may identify that sampling is required due to existing risks or as a control and management precaution. In this instance sampling then becomes a requirement from your assessment. Without an L8 risk assessment you will not know where and how many samples are required. And without water testing/sampling you cannot determine how affective your control and management is. These two actions therefore should be undertaken together, not necessarily at the same time but unison to effectively management your risk from legionella.
Water testing services include Legionella, e-Coli, total viable count (TVC), Pseudomonas, hard water, chlorine free, pH levels and more. Learn more about legionella testing. We only use UKAS approved laboratories giving you peace of mind that the test will be of the highest quality possible.
How much does an L8 risk assessment cost?
All assessments vary in prices depending on the number of water outlets, cold water storage tanks, hot water cylinders, combi boilers and other water assets that may be present. The number of assets within your water system will determine the time spent on site and how long it will take to produce your report.
So how much does it cost? Across the industry, prices vary enormously often depending on the size of the company you use and their processes, the speed of works and professionalism. There are two types of assessments, the first is commercial and the second domestic, also referred to as residential rental properties or landlord risk assessments.
Commercial risk assessments normally start from £250 to in excess of £750, however our prices start from £99 depending on the size of the water system and location.
Domestic risk assessments can range tremendously with a number of plumbers, gas engineers and other tradesmen offering these assessments without the specialist training, it’s important to check that your assessor or engineer is properly qualified. Our prices start from £55 for multiple landlord properties to £95 for single landlord properties. Our prices for residential rental properties are based on the property being no more than 5 bedrooms.
How long will the risk assessment take?
On average, the time our qualified assessor spends on site is 1 hour for every 10 outlets (sinks, showers, baths, etc). So an assessment can take anywhere between 30 minutes to 6 or 7 hours. It entirely depends on the size of your water system and the number of water assets you have such as cold water storage tanks, cylinders or combination boilers.
Our engineers will work closely with you to ensure minimal disruption to your business is caused. Clear and easy access to rooms and buildings will play a part in time spent on site at your premises.
When will I receive your findings?
You will receive your LRA report between 2-10 working days from the date the assessment was carried out. From time to time, not often, our team will need a little more time, so please expect to have your report no later than 30 days. Need your assessment sooner? Get your report, guaranteed next day delivery via email for just £50.
What happens after I receive the report?
Within your report document, you will have an action plan offering guidance which lists all identified risks, with photos, that need remedying in order of importance. By following our advice and undertaking remedial works you will reduce the risk of exposure to Legionnaires' disease. Once all the remedial works are complete, you will then need to focus on implementing your monitoring (periodical checks and maintenance) with a logbook for recording keeping all legal duties and monitoring requirements.
