Is Your LEV System Legally Compliant? What UK Employers Must Know in 2026

Reviewing LEV compliance starts with evidence about your own systems: what they control, how they perform, when they were examined and whether defects were addressed. Use this employer checklist to organise that review in 2026.

Start with the risk assessment

Identify the substances and processes that can expose people to harm. Decide how exposure will be prevented or adequately controlled. LEV is one possible engineering control; the appropriate combination of controls depends on the work and assessment. Simply having extraction installed does not establish adequate control.

Check the system information

Keep operating instructions and commissioning information. The commissioning record helps show intended performance and the conditions under which the system was assessed. Review the design when machinery, materials, extraction connections or working methods change.

Confirm examination dates

Most LEV systems require a thorough examination and test at intervals of no more than 14 months. Some specified processes have shorter requirements. Check the applicable interval and allow time to arrange the next examination before it is due.

Use an examiner with the knowledge, skills and experience appropriate to the system. Keep examination records for at least five years and make them available for review.

Close out defects

For each finding, record the action, responsible person and completion evidence. Consider whether affected work can continue safely while defects remain. After repairs or alterations, agree what checks are needed to demonstrate performance before normal use resumes.

Maintain and use the equipment correctly

Follow the system’s instructions for user checks, cleaning and maintenance. Ensure operators understand hood positioning, indicators and how to report faults. Investigate visible escape of contaminants, unusual noise or changes in airflow.

Review the whole control arrangement

A satisfactory LEV examination is one part of managing exposure. Working methods, supervision, other controls and any need for exposure monitoring also matter. Do not treat a report as a blanket certificate covering every task or future change.

What is LEV and why is it important for UK workplaces?

Local Exhaust Ventilation (LEV) systems are designed to control airborne contaminants such as dust, fumes, and vapours at their source. They are essential for protecting employee health, improving air quality, and ensuring compliance with UK workplace safety regulations.

Is LEV testing a legal requirement in the UK?

Yes, under COSHH regulations, UK employers must ensure that LEV systems are thoroughly examined and tested at least every 14 months. Failure to comply can result in penalties, legal action, and increased health risks for workers.

How often should an LEV system be serviced and maintained?

While thorough examination is required every 14 months, regular maintenance should be carried out more frequently depending on usage. Routine checks help ensure optimal performance, reduce downtime, and extend system lifespan.

What happens if my LEV system is not compliant?

Non-compliance can lead to serious consequences, including fines, enforcement notices, business disruption, and potential harm to employees. It can also damage your company’s reputation and lead to costly operational delays.

How can employers ensure their LEV system remains compliant in 2026?

Employers should schedule regular inspections, keep detailed records, train staff, and work with qualified LEV specialists. Staying updated with UK regulations and investing in professional monitoring services ensures ongoing compliance and workplace safety.
