Asbestos Testing in Preston for Licensed Removals

Asbestos Testing in Preston for Licensed Removals

After an asbestos removal has been carried out, the air inside, and external to the site, has to be tested to ensure it complies with European standards. Avanti uses UKAS accredited consultancies to carry out the testing process. They ensure compliance with the ISO17025 standard.

Four-stage clearance is the required process of air monitoring following asbestos removal in Preston. This is in accordance with HSE guidance note HSG 248.


An initial inspection of the site in order to check the condition of the premises, and that the removal works have been completed satisfactorily.


A detailed visual inspection determines whether the work enclosure is clean and fit for re-occupation.


Air monitoring is carried out inside the work enclosure. This will determine whether or not the density of asbestos fibres in the air meets with recommended limits.


Once the air monitoring checks are concluded satisfactorily, a certificate of re-occupation can be issued, and the work enclosure is taken down.

Avanti provides air monitoring, asbestos removals and asbestos surveys for Preston commercial and domestic clients.

  • Background Air Monitoring – Used to provide confirmation that the recommended level for asbestos fibres is not breached.
  • Leak (enclosure check) Monitoring – Carried out during asbestos removals. Air samples are taken outside the enclosure to assess its integrity.
  • Personal Compliance Monitoring – This air monitoring test checks that the control measures inside the enclosure are appropriate for the level of RPE (respiratory protective equipment), being worn during the asbestos removals.
  • Clearance air monitoring – Determines whether the air in an asbestos removal work site complies with the recommended limits.
  • Reassurance Monitoring – Such testing is conducted, for example, after a work site enclosure has been removed.
