When is an asbestos licence required?
Work with particular asbestos-containing materials can only be carried out by somebody who holds a licence issued by HSE. Licences are granted for a limited period of time (usually one or three years), enabling HSE to review licences and the performance of licence holders at regular intervals. For more information, see: Asbestos licensing.
Not all work with asbestos materials requires a licence. However, all work with sprayed asbestos coatings, asbestos insulation or asbestos lagging and most work with asbestos insulating board (AIB) requires a licence because of the hazardous nature of these higher risk materials. For information on when you might require a licence and the application process, see: [Licence application](http://www.hse.gov.uk/asbestos/licensing/application.htm#whendoi).
For those doing licensed work, the current Regulations require that employers must keep a health record for employees and they must also be kept under regular medical surveillance. The health record must be kept for 40 years after the date of the last entry in it. If an employee has been exposed to asbestos, the health record must note the following:
the date, time and how long the exposure to asbestos was for
the type of asbestos (if known)
the levels of asbestos exposed to (if known)
