Local Exhaust Ventilation (LEV) testing

Certified Local Exhaust Ventilation (LEV) testing and thorough examinations across the UK. Ensure your spraybooths, prep decks, sanding benches, and dust extraction systems remain fully compliant with COSHH Regulation 9.

Every employer operating local exhaust ventilation equipment has a strict legal duty to ensure it is maintained in an efficient state, in efficient working order, in good repair, and in a clean condition. Our BOHS-qualified engineers conduct comprehensive statutory examinations, complete diagnostic airflow checks, and supply legally defensible certification to keep your workforce safe and your facility audit-ready.

The Legal Requirement: COSHH Regulation 9

Under the Control of Substances Hazardous to Health (COSHH) Regulations 2002 (Reg 9), most LEV systems require a Statutory Thorough Examination and Test at least once every 14 months (or more frequently for high-risk processes). Insurers and HSE inspectors routinely ask for these records first following any site inspection or workplace incident.

Our LEV examinations follow the HSE guidelines set out in HSG258 (Controlling Airborne Contaminants at Work) and assess the entire extraction chain:

Hood & Enclosure Capture: Measuring capture velocities and face velocities to ensure paint mist, dust, or vapours are drawn away from the operative’s breathing zone.
Ductwork & Airflow Velocity: Checking transport velocities within duct runs to prevent hazardous particulate drop-out, settling, or blockages.
Static Pressure & Filter Condition: Assessing differential pressure across primary and secondary filter stages to ensure balanced airflow.
Fan & Drive Performance: Inspecting fan condition, impeller wear, drive belts, and motor performance against original design criteria.
Visual Inspection: Checking the physical integrity of duct seals, flexible couplings, access hatches, and discharge cowls for damage or leaks.

Comprehensive Documentation & Actionable Reports

Following testing, we supply a detailed, plain-English LEV Report and Certificate of Thorough Examination. The report clearly documents:

Airflow measurements, static pressures, and velocity profiles across all capture points
Photographic evidence and schematic references of the tested system
Pass / Fail status against statutory standards and baseline commissioning data
Prioritised remedial recommendations to fix defects before your next HSE audit
Inspection record labels affixed directly to the LEV unit displaying test date and re-test deadline

The All-in-One Compliance Visit

Avoid coordinating multiple contractors and paying separate call-out fees by bundling your legal safety checks into a single site visit. Our engineers can carry out your Quarterly Breathing Air Quality Check (BS EN 12021), Annual LEV Thorough Examination (COSHH Reg 9), and Spraybooth Smoke Clearance Time Test on the exact same day. We handle the scheduling, provide synchronised reminder alerts, and supply consolidated digital certification to keep your workshop audit-ready at lower overall cost.
