Quick answer
An asbestos sample is a small (10–50p sized) piece of suspect material taken under controlled conditions — wet method, PPE, sealed containers — and sent to a UKAS-accredited laboratory. The lab identifies fibre type and content using polarised light microscopy. Results normally return within 48 hours.
On site
The surveyor cordons off a small work area, wears coveralls and P3 RPE, wets the material lightly, takes a small representative sample with a sharp tool, seals it in a labelled bag, wipes the tool clean, and seals the sample site.
At the lab
The UKAS-accredited lab identifies fibre type (chrysotile, amosite, crocidolite) using polarised light microscopy (PLM) with dispersion staining. A certificate is issued for each sample, showing fibre type, colour, matrix and any negative result.
In the report
Each sample is cross-referenced to the register entry, with photograph, location, condition score and recommended action. Positive samples receive risk scores; negative samples remove suspicion permanently.
Frequently asked questions
Common questions
How much does a single sample cost?+
Typical £30–£50 plus VAT per sample as part of a survey. Standalone sample-only work is £75–£120 plus VAT for a single-sample visit.
Can I take my own sample and post it?+
Yes — we offer a postal service with dust masks and instructions. In practice, disturbance risk is why most homeowners have a surveyor attend.
