Asbestos is a group of minerals that are fibrous and heat-resistant. They were widely used in building materials in the UK until the 1990s because of their properties such as strength, durability and insulation. However, asbestos is very harmful to human health and can cause serious lung diseases such as asbestosis and mesothelioma.

Asbestos is usually safe when left undisturbed, but when the fibres are released into the air, they can be inhaled and cause serious harm to the lungs. That's why it's important to have your property tested for asbestos before carrying out any renovation or demolition work.
