LEV Testing is required by law.

LEV testing is a critical process that assesses the effectiveness of Local Exhaust Ventilation systems in removing airborne contaminants before they can be inhaled by workers. This testing is a legal necessity to ensure that these systems are up to the task of protecting employee health.

Our service offers a thorough examination and testing of your LEV system, conducted by experienced professionals. This is not a mere operational check; it’s a detailed analysis to ensure your system meets the comprehensive guidelines set out in the HSE258 document. This involves inspecting the system’s performance, examining its condition, and verifying that it is capable of providing the necessary level of protection against hazardous substances.

Our prices are based on testing one point or one outlet coming from your extractor to the source of dust ie a band saw for example with one length of duct would be classed as one point.

If you have lots of dust extraction systems with many points we can carry this out on a discounted daily rate, please contact us for a full no obligation site survey and quotation.

Local Exhaust Ventilation (LEV) is a way of managing and decreasing the exposure of employees to airborne dirt, dust, fumes and vapours which may be hazardous to health. A LEV system (dust collector) would remove the dust via a hood connected to ducting that has powerful suction provided by a fan. This would remove dust from the local area and either discharges it in to a larger filtration system or in to a local filter connected to the LEV system. The clean air is then released back in to the local atmosphere where it is now clean is no longer a hazard to employees.

In a word yes. Under the Health and Safety at Work acts of 1974, plus Regulation 9 of the Control of Substances Hazardous to Health, regulations state that any LEV systems must be maintained in a good working order and in good repair. By making sure your LEV systems meet all health and safety regulations you’re not only protecting your employees you’re also protecting you and company in the event that a member of your staff becomes seriously ill or injured while carrying out their duties.

All LEV systems must be tested at least every 14 months although some systems require more frequently depending upon their use and processes. CoSHH Regulation 9 also states that a record must be kept of all, faults, checks, maintenance, repairs and service. Those records should be kept in a service log for each LEV system and held for a minimum of 5 years.

An LEV test should will include a visual inspection of the full system to check for signs of broken/faulty parts. Once this has been completed the engineer will need to use specialist testing equipment to ensure the system is performing to the correct performances that the system is s designed for. This test is usually carried out with the system running at normal operating conditions.

Where the system passes the entire test the engineer will enter all of the details, as well as the results, in to the log book for that particular piece of LEV plant. If any part of the system should fail the test then our engineer will advise you accordingly including a recommended action to remedy the problem. We offer a full comprehensive LEV reporting and can offer you ta quote for any remedial works that may need to be carried out to gain a pass.


There are certain regulations for companies that provide Local Exhaust Ventilation services and these are outlined by the HSE (Health and Safety Executive). Regulation 9 of CoSHH also provides guidelines for the provisions of LEV testing service providers. As stated on HSG258, the person who services or repairs your LEV system should be BOHS P601 qualified.

Our LEV testing engineers are P601 qualified minimum.

P601 – “Thorough Examination and Testing of Local Exhaust Ventilation Systems”
P602 – “Basic Design Principles of Local Exhaust Ventilation Systems”.

Details of these qualifications can be found on the British Occupational Hygiene Society (BOHS) website

We have a dedicated team of trained LEV engineers (we cover all of the UK) are able to inspect, test and repair any type of LEV plant regardless of the manufacturer or supplier. Our specialist team are P601, P602 qualified as standard. Which is your guarantee that whatever type of LEV system you’re using we can inspect it, test it and repair it.

This means your downtime is reduced while also ensuring your LEV systems are maintained to give peak performance.
