Surveying and Sampling Strategies for Asbestos in Buildings P402

Asbestos surveyors play an important role in ensuring that building premises are safe for normal occupational use. Following the Control of Asbestos Regulations (CAR) 2012, Regulation 4, they can play a key role in identifying and recording where asbestos is present and likely to be disturbed in a premises and then starting the assessment of that material to determine how hazardous it is. 

They also play a crucial role during refurbishment and demolition works to identify the asbestos within the scope of the proposed works, for it to be removed safely. The P402 - Surveying and Sampling Strategies for Asbestos in Buildings qualification gives surveyors the requisite background knowledge and practical skills to identify and safely survey buildings for asbestos. 

Who is it for?

This qualification is suitable for 

  • Asbestos surveyors, or managers of surveyors and surveying teams 
  • Asbestos re-inspectors, or anyone that undertakes asbestos re-inspections 
  • Those who require a detailed understanding of asbestos surveying principles (e.g. asbestos report writers, architects, building surveyors etc.) 


This is a level 4 qualification in the BOHS qualifications framework, equivalent to NVQ Level 4. 

How is it delivered?

The P402 course will require at least 18 hours of study time, of which at least 14 hours will be taught (teaching and practical assessments) and 4 hours will be independent (in your own time). In addition there will be 3 hours of examination time.
