Asbestos is a naturally occurring mineral that was widely used in building materials and construction products in the past. It was known for its durability and resistance to heat, making it perfect for insulation, roofing, flooring and other purposes.

However, studies have shown that asbestos exposure can lead to serious health problems, including asbestosis, mesothelioma and lung cancer. Therefore, the UK government has banned the use and import of all types of asbestos since 1999 and issued regulations to manage the remaining asbestos in buildings and public spaces.
