Validation of an air or water system can be required for many reasons. As well as carrying out thorough testing and commissioning of newly installed systems, at Comfort Services Group we offer verification and validation of established air and water systems. Validation is often required (or at least recommended) where an existing system has been dramatically altered or modified. It may also be that a property has been purchased, undergone a change of purpose or have been vacant for an extended period of time. In any of these examples it may be that a system has remained idle for a period of time and should be validated before being set to work again.
Expert Physical Inspection & Compliance Audits
Much like during the commissioning process, validation of an existing air or water system will follow a logical systematic process. A physical inspection of the system can be undertaken to ensure the system has remained compliant with all necessary regulations and policies. Our qualified engineers will identify and report on any part of a system which falls outside any legal regulation or the original brief and specification.
Common Scenarios Requiring System Validation
System validation is often needed when a property or water system reaches a clear point of change. This could be during a property handover, after a building has been vacant, or following major renovation works where pipework, tanks or connected services may have been altered. In these situations, validation gives duty holders, landlords, facilities teams and incoming occupants the due diligence they need before the system is relied on again. It helps confirm the condition of the water system, identify any hygiene or performance concerns, and create an operational baseline for future monitoring. For property owners and managers, this also supports liability protection by showing that reasonable steps have been taken to assess risk, document findings and bring the system back into safe, compliant use.
System Efficiency Testing & Performance Analysis
During the validation process we will compile detailed test documentation which allows our engineers to accurately assess the efficiency of the system. This data is compared against the measurement of current performance and recommendations can then be made as to how the system can be brought in-line with the original brief. At Comfort Services Group we provide a complete range of system testing from the basic measurement of air and water right through to exhaustive performance monitoring.

Meeting BSRIA and CIBSE Validation Standards
System validation is not just a quick check to see whether everything looks right. It is about proving that the system has been properly cleaned, flushed, treated, balanced and commissioned in line with recognised industry guidance. At Comfort Services Group, we work against trusted standards such as BSRIA BG29, BG50 and relevant CIBSE guidance, giving clients a clear, professional view of the system’s condition. This helps contractors, facilities teams and duty holders move forward with confidence, knowing they have reliable evidence for handover, compliance and future maintenance. It also creates a strong operational baseline, so any future changes or issues can be measured against a properly validated starting point.
Water Sampling: Potability & Legionella Testing
At Comfort Services Group, our validation services go far beyond testing the basic efficiency of your air and water systems. If the property operates closed chilled, condenser or hot water circuits (either LTHW or MTHW) we provide a water sampling service. Our microbiological water sampling services test for potability and Legionella. These water chemistry tests can be undertaken for both domestic and commercial systems and ensure the provision of safe, clean, drinking-quality water from your water systems.
Chemical Testing & UKAS Accredited Lab Reporting
With any validation service, particularly when testing is being undertaken on large commercial systems, it is essential that all chemical testing is conducted in such a way as to provide maximum assurances of safety. With that in mind, all air and water system validation services carried out by Comfort Services Group include ductwork swabs and a full independent summary report via UKAS accredited laboratories.
With more than 20 years experience, Comfort Services Group have the expertise to carry out validation testing of all types of air and water systems. Contact Comfort Services Group Ltd today to find out how we can help with your commissioning project.
Validation for Commercial and Industrial Facilities
Comfort Services Group carries out system validation for a wide range of commercial and industrial sites, including healthcare facilities, schools, universities, data centres and large office buildings. These environments often have bigger, more complex water systems, tighter compliance demands and very little room for disruption. Our team is used to working on sites where access, timing, documentation and system performance all need to be handled carefully. For larger or more demanding buildings, we bring the experience, structure and technical support needed to do the job properly, especially where a smaller firm may not have the capacity or specialist knowledge required.
Discuss Your System Validation Requirements with an Expert
Every water system is different, so the right validation approach depends on your building, its usage, recent works and any compliance concerns already identified. If you are unsure what level of validation is needed, speak with a qualified Comfort Services Group engineer for practical advice based on your specific system. We can review your requirements, explain the most suitable next steps and provide a tailored quote for the work required, whether you are preparing for handover, bringing an idle system back into use or checking a complex commercial or industrial installation.

Frequently Asked Questions
Why is Air and Water System Validation Important for Compliance?
Validation can be seen, in essence, as a secondary form of commissioning for systems that have already been operational within a building. Validation services are important in ensuring that existing systems are performing correctly and efficiently and that it is safe and effective to continue its operation.
When Does Your System Require Validation Testing?
There are a number of situations where validation of an existing system should be carried out (or will, at least, be potentially beneficial);
If a system has been inactive for a substantial period of time then validation may be required to ensure that a system is operating in-line with its original brief. This is likely to occur when a property has been vacant for an extended period and has only recently become reoccupied.
When a system is modified outside of its original specification validation may be required in order to ensure that the system is still fulfilling its original brief or, where the purpose of the system has been changed, it is now fulfilling an amended purpose.
If you have recently taken over and become responsible for a new building it may be that original commissioning, testing and maintenance records for the site’s air and water systems are unavailable or, at best, incomplete. At this stage validation can be essential to ensure that systems are running in accordance with Legionella Risk regulations.
What is Included in a Professional Validation Inspection?
When undertaking validation on an existing (or newly modified) system there are number of forms of testing and inspection that we carry out: Our experienced engineers will undertake a physical system inspection to ensure that the system continues to meet its brief and in currently in-line with required regulation.
Our Engineers will then carry out a diverse range of tests and assessments on the system to determine its current performance levels. This system testing will identify parts of the system which are not performing correctly and may need replacement or maintenance in order to optimise the performance of the system as a whole.
Water Sampling and Chemical Testing will be undertaken in-line with Legionella Risk Assessment requirements. This part of our validation service helps to ensure that your obligations as property manager are met.
