What Does LEV Testing Include?

A thorough examination and test assesses the extraction system against its intended performance and the process it serves. We inspect the equipment and its use, take appropriate measurements and explain defects or limitations.

  • Inspection of hoods, ductwork, filters, fans and visible damage.

  • Airflow and pressure measurements appropriate to the system.

  • Assessment of contaminant capture during normal work, where safe and practical.

  • Review of available commissioning data, previous reports and maintenance records.

Your written report records the system assessed, test findings, identified defects and recommended actions. We explain any restrictions on what could be examined so you can plan the next steps.

Often called COSHH LEV testing, this examination checks performance; servicing maintains equipment and repairs address faults. A running fan alone does not demonstrate effective dust or fume control.

Planning Your LEV Test

Share Your System Records

Send your previous examination report, commissioning information and details of recent repairs or process changes. These help establish what the system should achieve.

Show Normal Working Conditions

Arrange access to the equipment and, where safe and practical, demonstrate the process in normal use. How operators position and use extraction matters to its performance.

Allow Safe Access

Tell us about access restrictions, working hours and site safety requirements when booking. The number of systems and test points will affect the time needed.

Understand Your Report

Read the findings and ask about anything unclear. The report should explain the assessed performance, any defects and the actions needed to address them.

Act on Defects

Address problems promptly and assess whether affected work can continue safely. We can discuss remedial work and any checks needed after repairs or alterations.

Plan the Next Examination

Most LEV systems need thorough examination and testing at least every 14 months; some require shorter intervals. Keep examination records for at least five years. Routine maintenance is also needed between tests.

LEV Testing and Follow-up Support

Based in Chorley, Lancashire, Premier LEV supports workplaces across the UK with testing, servicing, repairs, replacement filters and installation.

If an examination identifies defects, we explain the findings and discuss practical next steps. Our laser extraction case study shows how an unsatisfactory examination led to ductwork repairs and a subsequent satisfactory retest.
