COSHH Local Exhaust Ventilation Regulations

Employers in the U.K. who produce, handle, or use hazardous substances—such as dusts, fumes, vapours, and mists—are legally required to comply with the Control of Substances Hazardous to Health (COSHH) Regulations 2002. 

When exposure to these substances cannot be fully eliminated, it must be effectively controlled, with Local Exhaust Ventilation (LEV) systems serving as the primary engineering solution. 

COSHH Regulation 9 outlines the legal duties for maintaining and testing these systems, with Regulation 9(2) setting a statutory maximum inspection interval of 14 months. Although this meets the minimum legal standard, industry best practice recommends annual (12-month) inspections to reduce risk. 

Operating close to the 14-month limit increases the chance of system degradation—due to damage, filter loading, or material build-up—which can compromise airflow and control effectiveness well before the deadline.

What the FAQ?

What is COSHH LEV Testing?

Answer. COSHH LEV Testing, or Thorough Examination and Test, is a legal requirement under the Control of Substances Hazardous to Health (COSHH) Regulations 2002 (Regulation 9). It is a systematic, detailed inspection and performance check of Local Exhaust Ventilation (LEV) systems to ensure they remain effective in controlling employee exposure to hazardous substances like dust, fumes, and vapours.

How often do I need to get this testing done?

 Answer. By law, most LEV systems must undergo a Thorough Examination and Test at least once every 14 months. However, systems handling very high-risk substances may require more frequent testing, as specified in COSHH guidance or your risk assessment.

Is LEV testing a legal requirement?

Answer. Yes. Regulation 9 of COSHH legally mandates that employers must ensure their LEV equipment is maintained in an efficient state, in efficient working order, and in good repair, which includes having a thorough examination and test by a competent person.
