LEV Testing · Hertfordshire
LEV testing across Hertfordshire - the county town, the garden cities and the technology and research estates. COSHH thorough examination and test of the fume and dust extraction in your workshops - measured, reported and certified.
Hertfordshire runs from the cathedral city of St Albans and the county town of Hertford through the new town of Stevenage and the garden cities of Letchworth and Welwyn, out to Watford, Hemel Hempstead and Borehamwood on the London edge and up the Lea Valley through Hoddesdon and Cheshunt. It is a county of commuter towns, garden cities and the technology, research and film estates that define its economy.
Every workshop across Hertfordshire that welds, machines, sprays, mills or bakes raises fume, mist or dust the law says must be controlled. We examine and test local exhaust ventilation across Hertfordshire to HSG258 - measured capture, a clear verdict and a reliable next-due date, from Borehamwood to Watford.
A thorough examination and test under COSHH is a real assessment, not a rubber stamp. It is a structured examination of the system's condition, measurement of its actual performance, and an assessment of those readings against how the system should perform to control the exposure. It follows the HSE's guidance, HSG258, and ends in a report and a label.
From a Stevenage defence works to a Borehamwood scenery shop, the job ends in a report and a label - what was measured, what passed, and the date the next test falls due.
Control is won or lost at the hood. We measure capture and face velocities where the fume, mist or dust is released, not merely at the fan.
Transport velocity, leakage and the state of the filter or air cleaner all decide whether the contaminant reaches discharge. We inspect and measure the whole route, not a sample.
Fan performance and static pressure are where a quietly failing system shows itself. We take the readings that tell a working system from one that only looks the part.
We cover the whole of Hertfordshire - every town below has its own page for this service.
Hertfordshire raises fume and dust across a research and light-industrial economy, and each site owes the same duty to control it and prove it. Stevenage builds space and defence hardware and Watford runs high-technology and battery-cell production, while Borehamwood constructs film scenery and sets and Letchworth prints and binds books. Hertford brews, Hoddesdon grows under glass in the Lea Valley, Hemel Hempstead mills feed, Harpenden runs the Rothamsted agricultural-research laboratory and Bushey works precious metal, with engineering and finishing units throughout. We examine and test the extraction on all of it to HSG258.
We examine the hoods, ducting, filter and fan and identify how each is meant to control its process.
We record capture and face velocities, transport velocity and static pressure at every key point.
The readings are assessed against the design intent under HSG258, with a clear verdict on control.
The plant is labelled with the result and next-due date, and you get the report for the COSHH file.
Yes - across the county, from St Albans, Watford and Hertford to Stevenage, Hemel Hempstead, Letchworth, Borehamwood, Bushey, Harpenden, Hoddesdon and Cheshunt. Each town has its own page for this service; call 07961 915018 or use the contact form and we will confirm and quote.
Yes. We look after multi-site operators across Hertfordshire on one schedule - a single survey, one set of certificates and a next-due date per site - so a group with kitchens in several towns keeps its compliance in one place.
Yes. We work overnight, early mornings, weekends and closing days so a Hertfordshire kitchen or workshop keeps running while we clean, degrease or test.
Yes. Duct and extraction cleaning is certified to TR19 Grease with a photo record, kitchen deep cleans carry a certificate and report for your food hygiene file, and LEV testing is reported and labelled to HSG258.
We have carried out LEV thorough examination and testing to HSG258 since 2001, across Hertfordshire and the UK. From a machine shop to a joinery, a spray booth or a lab fume cupboard, the job ends the same way: measured readings, a clear verdict, and a label whose next-due date you can rely on.
Tell us your site and we will survey, quote and certify - anywhere in Hertfordshire.
