Closed System Testing Analysis
Regularly testing your closed heating or cooling system for microbiological and chemistry levels ensures your system is under control and is a preventative task that helps reduce risk of system failure, corrosion, scale, poor flow and bacterial growth. All of which can help reduce large bills to repair inevitable system failures if no testing is carried out. Such testing can help identify sufficient chemical inhibitor levels such as Molybdate and Nitrite.
uRisk is a nationwide water hygiene company with City and Guilds trained engineers who have experience in industrial, commercial and domestic heating and cooling systems.
How often should I Test my Closed System?
Closed System Testing frequency is carried out every 3 months (quarterly) or when a system has changed where there is new or additional pipework.
How long does Closed System Testing take?
Closed System Testing can take up to 1 hour depending on the design and heating system you have installed.
What happens after the Closed System Testing Results
Once you receive you Closed System Testing Results you will be advised on the next steps to take. In most instances you will be advised to have your system dosed with either inhibitor and/or biocide. You may also be advised that further Closed System Testing is required to interpret how the inhibitor and/or biocide has impacted your system.
How much does Closed System Testing cost?
Closed System Testing prices may vary depending on the size, quantity of your systems and site requirements, but industry prices generally range between £100 to £400 per system test.

How to make my Heating System or Cooling System more Efficient?
New systems are often higher more efficient systems heating systems and cooling systems due to technology upgrades. But how do we keep our heating systems and cooling systems efficient; and how do we make old and existing heating systems and cooling systems last longer?
Preventative monitoring and servicing can play an important role in avoiding large bills for faults and replacement costs for heating and cooling systems. Below are just a few ways you can avoid those unwanted expensive bills:
- Designed correctly and fit for purpose
- Installed correctly
- Cleaned & commissioned correctly
- Maintained correctly
Failure to ensure any one of these 4 items will results in poor system performance, a reduce system lifetime and more expenses.
What happens if I do not treat my Closed System?
Systems that are not treated at least annually (commercial systems bi-annually) will begin to suffer from scale, corrosion, and gassing can occur as well as the potential for microbiological proliferation. System efficiency can see up to 30-40% reduction in system efficiency on sludgy and fouled systems.

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.
