Sampling and bulk analysis
A small piece of the suspect material is taken and analysed in a laboratory to find out whether it contains asbestos and which type. This is the usual first step when you have one or two materials you are unsure about.
Confirming whether a material contains asbestos
Asbestos Testing and Sampling
You can't identify asbestos by looking. Laboratory analysis of a sample is the only way to confirm it.
Options
Which kind of testing do you need?
A survey
If you need to know about a whole property or all the areas affected by building work, a survey includes inspection, sampling and a report. See our survey guide.
Asbestos surveys explainedAir testing and clearance
Air samples measure fibres in the air. After licensed removal work, an accredited analyst carries out a four-stage clearance before a certificate for reoccupation is issued.
How it works
From sample to result
Someone trained takes the sample
HSE recommends a trained and competent person, such as a laboratory analyst or asbestos surveyor, because sampling can release fibres.
An accredited lab analyses it
Anyone commissioning analysis must use a laboratory accredited to ISO/IEC 17025. In Great Britain HSE recognises UKAS accreditation.
You get a written result
The certificate or report says whether asbestos was detected and, if so, the type. Keep it with your property records.
Good to know
- Should I take the sample myself? HSE advises using a trained person. Breaking off a piece of a higher-risk material such as insulating board or lagging can release fibres.
- Is the lab accredited? Search the UKAS directory of accredited organisations.
- What does it cost? Prices vary by laboratory, how many samples are taken and whether a visit is needed. We haven't found a reliable published range, so ask for a written quote.
- What if it's positive? It depends on the material and its condition. Asbestos in good condition is often best left in place and checked; damaged material may need sealing, enclosing or removal. Removal options explained.
