First, let's briefly discuss what asbestos is and why it's a problem. Asbestos is a naturally occurring mineral that was widely used in building materials due to its heat-resistant and durable properties. However, when asbestos is disturbed, it releases microscopic fibers into the air that can be inhaled, leading to serious health problems such as lung cancer, mesothelioma, and asbestosis.

Asbestos was banned in the UK in 1999, but it can still be found in buildings constructed before that time. That's why it's crucial to have an asbestos survey carried out if you're planning any refurbishment or demolition work on a building or if you simply want to ensure the safety of your occupants.
