Air Testing explained
Air testing pumps a measured volume of air through a filter, which is then counted under a microscope. It shows whether fibre levels are below the clearance indicator of 0.01 fibres per cm3.
It is used before work (background), during removal (leak and personal monitoring), after an accidental disturbance (reassurance) and at the end of licensed work (the four-stage clearance). Clearance certificates must come from an analyst independent of the removal contractor, and we arrange that for you.
Guide price: Background or reassurance tests from £250. Fixed written quote before any work.

Homes: reassurance after a builder or DIY job disturbed something by mistake.
Commercial
Commercial: schools, offices and care homes needing proof that an area is safe to re-open.
Industrial
Industrial: monitoring during large removal projects and around live production areas.

Air Testing questions
What is a four-stage clearance?
Four checks by an independent analyst: that the job is complete and the site is in order, a thorough visual inspection inside the enclosure, air testing, and a final check once the enclosure has been taken down. It is required at the end of licensed work.
Do you do the clearance on your own removal jobs?
No. Clearances are always carried out by an independent UKAS-accredited analyst, as required by HSE guidance.
How soon can you test after an incident?
Leave the area, close it off and call us. We aim to arrange testing as quickly as possible, often the same or next day.
What reading is safe?
The clearance indicator is below 0.01 fibres per cm3 of air.
