Yes, it is legal to remove small quantities of asbestos of under 10 square metres yourself.
However, unless you are experienced in the handling and disposal of asbestos and have all of the relevant safety gear, you are strongly advised to seek advice from a professional.
You can’t tell by just looking if there is asbestos on your property and the consequences of asbestos inhalation can be life-threatening, so it is safer to be cautious.
The investment to get the removal done safely and quickly is worth it.
