Asbestos is a naturally occurring mineral that was extensively used in the UK from the 1950s through to the mid-1980s in various forms. It was commonly used in construction materials such as roof tiles, insulation, and cement, among others.

Although asbestos has excellent insulation and fire-resistant properties, it is highly toxic and can lead to serious health problems, such as mesothelioma, lung cancer, and asbestosis. As a result, it is highly regulated in the UK, and it is illegal to use or import asbestos or asbestos-containing materials into the country.
