It depends on the circumstances. In general, you do not need permission to remove a tree on your property. However, there are some situations where permission may be required. For example, if the tree is protected by a Tree Preservation Order (TPO), you must apply for permission to remove it. Additionally, if the tree is located in a conservation area, you may need permission to remove it, even if it is not protected by a TPO. Before removing a tree, it is important to determine whether or not it is protected. Your local council can provide information about TPOs and conservation areas in your area. If the tree is not protected, it is still important to consider the impact of its removal on the environment and neighbouring properties. It is also worth noting that some local authorities have regulations in place to protect trees from removal, even if they are not protected by a TPO or located in a conservation area. It is best to consult with a professional arborist or your local council before removing any trees on your property to ensure that you are following all necessary regulations and guidelines.
