LEV Testing · Wiltshire
LEV testing across Wiltshire - the railway town, the cathedral city and the market and technology towns. COSHH thorough examination and test of the fume and dust extraction in your workshops - measured, reported and certified.
Wiltshire runs from the railway town of Swindon through the market towns of Chippenham, Trowbridge, Marlborough and Malmesbury to the cathedral city of Salisbury. It is a county of market-town kitchens and the engineering, technology and food estates of the south-west.
Every workshop across Wiltshire 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 Wiltshire to HSG258 - measured capture, a clear verdict and a reliable next-due date, from Chippenham to Trowbridge.
The point of a thorough examination and test is to prove the extraction still controls the exposure - so we measure it, we do not eyeball it. Condition, capture and face velocities, transport velocity and static pressure are checked against the design intent under HSG258, and the result is written up and labelled on the plant.
From a Malmesbury motor works to a Trowbridge flour mill, the job ends in a report and a label - what was measured, what passed, and the date the next test falls due.

Control stands or falls at the hood. We measure capture and face velocities at the point the fume, mist or dust is actually released, not just at the fan.
Transport velocity, leakage and the air cleaner all decide whether the contaminant reaches discharge. We inspect and measure the length of the system, not a sample of it.
Fan performance and static pressure are where a quietly failing system gives itself away. We take the readings that separate a working system from one that only looks it.
We cover the whole of Wiltshire - every town below has its own page for this service.
Wiltshire raises fume and dust across an engineering, technology and food economy, and each site owes the same duty to control it and prove it. Malmesbury runs its electric-motor and technology works, Chippenham a plastic-pipe extrusion plant, and Trowbridge a flour mill, while Marlborough blends cosmetics and fragrance. Salisbury keeps a textile dye-house and Swindon its engineering and processing works, with fabrication units throughout. We examine and test the extraction on all of it to HSG258.
We inspect the system's condition - hoods, ducting, filter and fan - and identify how it is meant to control each process.
We take the readings: capture and face velocities, duct transport velocity and static pressure at the key points.
We assess the readings against the benchmark and set out clearly whether the system is controlling the exposure.
The system is labelled with the test result and next-due date, and you get the report for your COSHH file.
Yes - across the county, from Swindon, Salisbury and Chippenham to Trowbridge, Marlborough and Malmesbury. 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 Wiltshire 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 Wiltshire kitchen or works 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 Wiltshire 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 Wiltshire.
