Asbestos is a naturally occurring mineral that was widely used in construction materials in the 20th century due to its heat resistance, insulation properties and affordability. However, it was later discovered that asbestos fibers can cause severe health problems when inhaled, such as lung cancer, mesothelioma, and asbestosis.

Therefore, the use of asbestos has been banned in the UK since 1999, and all buildings constructed before that year are likely to contain asbestos-containing materials (ACMs). That's why an asbestos survey is crucial before carrying out any renovation or demolition work.
