Asbestos is a dangerous mineral that was commonly used in construction materials such as insulation, roofing, and flooring. It was banned in the UK in 1999, but it still exists in many buildings constructed before this time. When asbestos-containing materials are disturbed or damaged, they release microscopic fibers, which could cause serious long-term health problems such as lung cancer, mesothelioma, and asbestosis.

The Control of Asbestos Regulations 2012 requires all duty-holders to identify the presence of asbestos in their buildings and manage the risks associated with it. This includes conducting an asbestos survey before any refurbishment or demolition project, as airborne asbestos fibers can be released during these works.
