Asbestos is a group of naturally occurring minerals that were commonly used in building materials due to their heat resistance, strength, and durability. The use of asbestos in building materials was banned in the UK in 1999. However, many buildings constructed before this date may still contain asbestos.

Asbestos can be extremely hazardous to health if its particles are released into the air and inhaled. This can cause a range of serious respiratory diseases, including lung cancer, mesothelioma, and asbestosis.
