From 6 April 2012, brief written records should be kept of non-licensed work, which has to be notified e.g. copy of the notification with a list of workers on the job, plus the level of likely exposure of those workers to asbestos.
This does not require air monitoring on every job, if an estimate of degree of exposure can be made based on experience of similar past tasks or published guidance.
By April 2015, all workers/self employed doing notifiable non-licensed work with asbestos must be health surveillanced by a Doctor.
Workers who are already under health surveillance for licensed work need not have another medical examination for non-licensed work however medicals for notifiable non-licensed work are NOT acceptable for those doing licensed work
