Dangerous Trees on private land

The Council will only deal with trees that are imminently dangerous and are at risk of causing life-threatening injury.

Trees can become imminently dangerous due to a singular event such as a storm, flood or vehicular damage in an accident, resulting in part, or all, of the tree presenting a danger to the public.  Alternatively, a tree may reach a dangerous state by ongoing decay or disease, or may have grown in such a way as to be structurally unsound.

The Council will only investigate complaints if the tree is considered imminently dangerous. For example, a large broken hanging branch or severed roots allowing an entire tree to rock at soil level. 

The Council will not deal with trees where there is a perceived danger, such as a tall tree, one close to a building or one that sways in the wind.  These trees are not considered to be in a dangerous condition and pose no imminent danger. The Council will not consider the prospects of the future condition of the tree and will only consider its current condition.

If you consider a tree to be imminently dangerous and there is a risk of causing life threatening injury, then please report the matter to the Public Health and Protection Section via 01443 425001. At the time of making the report you must state why you think the tree is imminently dangerous and who it will affect if the whole tree or parts of the tree were to fall.

If the tree is on private land and you deem it dangerous:

  1. you will need to complete a Dangerous Tree Questionnaire
  2. include photographs of the issue(s)/tree(s)
  3. include evidence of attempts to contact the landowner
  4. Arboricultural evidence that the tree(s) or branch(es) are dangerous.


A completed dangerous tree questionnaire, with the associated evidence, should be submitted directly to Public Health at
