Asbestos is a naturally occurring mineral that was commonly used in building materials throughout the 20th century. It was prized for its durability, heat resistance, and insulation properties. However, it was later discovered that exposure to asbestos can cause serious health problems, including lung cancer, mesothelioma, and asbestosis. As a result, the use of asbestos in building materials was banned in the UK in 1999.

While the use of asbestos in building materials is no longer permitted, many older buildings still contain asbestos. If you suspect that your building may contain asbestos, it's important to have it properly surveyed by a qualified professional.
