LEV testing and certification in Leeds

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

Across Leeds, from manufacturing and engineering to healthcare and laboratories, extraction keeps hazardous dust, fume and vapour out of the air. COSHH requires that local exhaust ventilation to be thoroughly examined and tested at least every 14 months by a competent person.

Extraction we test

LEV testing and certification for Leeds businesses

Your COSHH assessment decides what control each process needs, and the LEV examination is what proves the extraction is delivering it in practice. The test gauges how strongly each hood pulls the contaminant in, how the air moves through the ducts and how the filters and fan are holding up, all against the design and HSG258.

That closes the loop between the risk assessment on paper and the plant on the floor, whether the process throws off welding fume, dust, mist or vapour. If the examination shows control falling short, both the system and the assessment behind it need another look.

COSHH FAQs

LEV testing and certification: common questions

Do you carry out LEV testing in Leeds?
Yes, our P601 engineers cover Leeds and the surrounding Yorkshire towns, from a single extractor to a building full of systems. Call 0330 043 8191 and we will arrange a visit around your schedule.
How quickly can you visit Leeds?
We keep availability across Yorkshire, so a Leeds visit is usually only a few working days away, sooner for an urgent re-test. Call 0330 043 8191 to arrange around your work.
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.
