Never try to remove asbestos yourself, removal should only ever be performed by a licensed contractor.
Always get professional help when removing materials containing asbestos.
Breathing in asbestos dust can lead to fatal lung diseases, so professional contractors will always remove materials containing asbestos in London with the necessary precautions to keep themselves and others safe. Of course, there are also strict rules surrounding the disposal of asbestos too, which your chosen contractor should do on your behalf.
Even if you are unsure whether materials in your home or elsewhere contain asbestos, always seek professional advice, as asbestos testing is a relatively easy task to arrange and is vastly preferable to the health implications of contact with asbestos dust.
