If you're planning an LEV Thorough Examination and Test (TExT), one of the first questions you're likely to ask is, "How much will it cost?" The answer isn't always straightforward because every Local Exhaust Ventilation (LEV) system is different. The cost of LEV testing depends on several factors, including the size of the system, the number of extraction points, accessibility, and the complexity of the work involved.
Understanding what influences the cost can help you budget more effectively and compare quotations with confidence. More importantly, regular LEV testing helps ensure your extraction system continues to control hazardous airborne contaminants and complies with the Control of Substances Hazardous to Health (COSHH) Regulations.
In this guide, we'll explain what affects LEV testing costs and why choosing a quality service often provides better long-term value than simply selecting the cheapest quotation.
The LEV testing cost depends on the size and complexity of your extraction system, the number of extraction points, accessibility, system condition, and the time required to complete the examination. Because every workplace is different, quotations are usually tailored to your specific LEV system rather than based on a standard fixed price.
No two LEV systems are exactly alike. A small workshop with one extraction unit requires significantly less inspection than a large manufacturing facility with multiple systems operating across several production lines.
When preparing a quotation, competent providers consider the amount of time, equipment, and technical expertise required to carry out a complete Thorough Examination and Test.
A professional LEV Testing service should include a detailed inspection, airflow measurements, performance testing, and a comprehensive report outlining the condition of your system and any recommended actions.
One of the biggest factors affecting the cost is the overall size of the LEV installation.
Larger systems generally require:
Testing a single extraction unit is naturally quicker than examining multiple interconnected systems across a large site.
Each extraction hood, booth, arm, or capture point needs to be assessed individually.
As the number of extraction points increases, engineers must carry out additional airflow measurements and visual inspections, which increases the time required to complete the examination.
For businesses operating multiple production areas, this is often one of the largest factors influencing the overall quotation.
Some LEV systems are straightforward, while others are designed to manage several different processes simultaneously.
Additional complexity may include:
Complex systems require more detailed testing to confirm that every part of the installation continues to perform effectively.
If your production processes have changed over time, LEV Design and LEV Consultancy services can help determine whether your existing system still provides suitable control for your current workplace.
The easier it is to access the LEV system, the more efficiently testing can be completed.
Testing may take longer if engineers need to inspect:
Preparing safe access before the visit can help minimise delays during the inspection.
The condition of your LEV system also affects the time required for testing.
Systems that receive regular servicing are generally easier to inspect than those with obvious defects or poor maintenance histories.
Examples include:
Routine servicing through LEV Maintenance Contracts helps keep systems operating efficiently and may reduce the likelihood that issues will be identified during the next Thorough Examination.
Previous LEV reports and maintenance records can help engineers understand the system before testing begins.
Useful documentation includes:
Having these documents readily available allows comparisons with previous inspections and can make the examination process more efficient.
A professional LEV Testing service involves much more than checking whether an extraction fan is operating. According to the Health and Safety Executive's HSG258 guidance, a Thorough Examination and Test should assess whether the LEV system continues to provide effective control of hazardous substances.
A typical examination includes:
This level of detail ensures employers understand the condition of their LEV system and any actions required to maintain effective control.
It's understandable to compare quotations when arranging LEV testing, but the lowest price doesn't always represent the best value.
A high-quality examination should provide:
The Health and Safety Executive (HSE) recommends that competent persons thoroughly examine LEV systems. Choosing an experienced provider helps ensure the inspection is carried out correctly and provides meaningful information about your system's performance.
LEV testing forms an important part of workplace health and safety, but it isn't the only consideration.
Many organisations also monitor wider occupational health risks through air quality assessments, noise surveys, cleanroom testing, hand-arm vibration assessments, and lighting assessments. Reviewing these alongside your LEV programme provides a more complete understanding of workplace conditions and helps businesses manage multiple health risks effectively.
Although maintenance and testing have different purposes, they complement each other.
Routine maintenance helps identify worn components before they fail, while periodic testing confirms the system continues to control hazardous substances effectively. The HSG258 guidance highlights the importance of maintaining LEV systems alongside regular Thorough Examination and Testing.
Combining routine maintenance with scheduled testing can help businesses:
The cost of LEV testing depends on several factors, including the size and complexity of your LEV system, the number of extraction points, accessibility, and the condition of the equipment. Choosing an experienced provider ensures your system receives a thorough assessment that supports both workplace safety and legal compliance.
DevineAir offers comprehensive LEV services. Contact our team today to discuss your LEV requirements and request a quotation tailored to your workplace.
LEV testing costs vary with system size, the number of extraction points, accessibility, and the complexity of the examination. Most providers prepare quotations based on the specific requirements of your workplace.
Every LEV system is different. Larger or more complex systems require additional testing, measurements, and reporting, which affects the time needed to complete the examination.
Routine maintenance helps keep systems in good condition and can reduce the likelihood that defects will be identified during testing, potentially saving time and future repair costs.
The best way to obtain an accurate quotation is to provide details about your LEV system, including the number of extraction points, the type of workplace, and any previous testing or maintenance records.
Installing an LEV system is just the beginning of managing dust, fumes, and vapours in the workplace. For this system to function efficiently, proper care and maintenance are essential. When this is ignored, risks to workers' health are greatly increased. Many errors can arise regarding LEV compliance. Small problems, such as examinations not taking place […]
Dust exposure is a common problem affecting workers in various industries, including construction, manufacturing, woodworking, and the pharmaceutical industry. Without effective management of dust exposure, workers would face health risks detrimental to the company. For this reason, it is important to understand LEV and dust monitoring. Despite their common pairing, each has its own purpose. […]
