LEV testing and certification in Wakefield

Thorough examination, testing and certification of local exhaust ventilation by a P601 qualified engineer

Wakefield's food, logistics and manufacturing sites use extraction to control the dust, fume and mist their processes give off. A thorough examination and test, due under COSHH at least every 14 months, confirms the whole system is doing its job, not just the hood.

Extraction we test

LEV testing and certification for Wakefield businesses

An LEV system does not finish at the hood: the captured contaminant still has to travel the ducts, pass through any filter and leave through a discharge that does not feed it straight back into the building. We measure capture velocity, airflow and duct velocities and filter and fan condition, and check where the system discharges, against the design and HSG258.

A discharge placed near a door, window or air inlet can undo the whole system by re-entraining contaminant, so it forms part of the examination. The approach is the same across welding fume, dust, mist and vapour.

How it works

Booking your LEV test in Wakefield

A visit follows the system end to end: we map the extraction points, measure each, and check the fan and discharge as well as the hoods. You receive a clear report with a verdict per point, photographs, any remedial actions and the next due date.

COSHH FAQs

LEV testing and certification: common questions

Do you provide LEV testing in Wakefield?

How often does LEV need to be tested?
Under COSHH Regulation 9 every local exhaust ventilation system must have a thorough examination and test at least every 14 months, and that interval is a legal maximum rather than a target. Higher-risk processes in COSHH Schedule 4 are tested far more often, in some cases monthly or six-monthly; the HSE sets this out in its guidance on LEV examination.
Is LEV testing a legal requirement?
Yes. The duty sits with the employer under COSHH Regulation 9, which requires extraction that controls a hazardous substance to be examined and tested by a competent person, and that responsibility stays with you even when the work is outsourced. You can read the duty in plain terms in our COSHH regulations guide.
What does an LEV thorough examination and test involve?
It is a structured check that the system still controls the contaminant the way it was designed to, not a service or a filter swap. We measure airflow and capture velocity at each hood, check duct velocities, filters and fan condition, and compare every reading against the design data and the HSG258 benchmarks.
Who is qualified to carry out LEV testing?
The HSE expects a competent person, which it links to BOHS-recognised training such as the P601 qualification. Our engineer surveyors hold P601 and report to the HSG258 standard, so the examination stands up to scrutiny.
What is in the LEV report, and how long must I keep it?
You receive the measured airflow and capture data, a pass or fail verdict at each test point, photographs, any remedial actions and the next due date, and it is this report an inspector asks to see rather than a service record. COSHH requires the records to be kept for at least five years, so we log every result against your system.
What happens if my LEV system fails the test?
The report sets out exactly why, for example low airflow, a worn fan or a badly positioned hood, and the remedial work needed to bring it back into adequate control. Once the work is done we can return to re-test and confirm the system is protecting people again.
