Asbestos is a naturally occurring mineral that was widely used in building materials from the 1950s through to the late 1990s. It was valued for its heat-resistant properties, making it popular in insulation, cement, and other building materials. However, it was later found to have harmful health effects, including cancer and lung diseases.

It is now illegal to use or import asbestos in the UK. However, many older buildings may still contain asbestos in their insulation, tiles, and other materials. If you suspect asbestos in your building, it's essential to have it tested to ensure the safety of your occupants.
