Asbestos is a naturally occurring mineral that was widely used in the construction industry due to its fire-resistant and insulating properties. It can be found in building materials such as insulation, pipes, ceiling tiles, and flooring, among others. Although its use was banned in the UK in 1999, many properties still contain asbestos, particularly those built before the 1980s.

Asbestos becomes dangerous when it is disturbed and the fibres are released into the air. When inhaled, these fibres can cause serious respiratory illnesses such as lung cancer, mesothelioma, and asbestosis. These diseases can take years or even decades to develop, making early detection and removal of asbestos essential.
