Asbestos is a naturally occurring mineral that was widely used in building materials in the UK, including insulation, roofing, and flooring. While asbestos was banned in the UK in 1999, any property built before then could still contain asbestos-containing materials (ACMs).

ACMs are not necessarily dangerous if they are in good condition and remain undisturbed. However, if they are damaged or disturbed, such as during renovation or demolition, they can release harmful fibers into the air that can be inhaled and cause serious health problems.

The risks from asbestos depend on a range of factors, including the type and condition of the material, the level of exposure, and the individuals susceptibility. However, exposure to asbestos is always dangerous, and even short-term exposure can lead to serious health problems in the future.
