If you’re worried that a tree may be unsafe, it’s important to act promptly but proportionately. Not all defects make a tree dangerous, this page explains how to recognise warning signs and what steps to take.
When should I be concerned?
You should take notice if a tree shows signs such as:
- Large dead or hanging branches
- Cracks or splits in the trunk
- Leaning that has recently developed
- Uplifted soil around the base
- Extensive decay or fungal growth
These do not always mean a tree is dangerous, but they can warrant professional assessment.
What should I do first?
- Keep people away from the area if there is an immediate risk
- Do not attempt major tree work yourself
- Take photographs if safe to do so
Neighbouring trees
If a tree growing on someone else’s land causes injury to someone or damage to property then the owner may be liable. If you think your neighbour’s tree might be dangerous then you should contact an arboricultural consultant for further advice. It is always best to settle a dispute about trees amicably and it is recommended that you try to resolve the matter by talking to your neighbours first. If the tree is identified as an immediate danger, and your neighbour has refused to address the problem, then the Council may intervene if formally requested to do so.
Protected trees and emergencies
If a tree is protected by a Tree Preservation Order (TPO) or is in a Conservation Area, permission is normally required before work.
However, emergency work to remove an immediate risk may be allowed. Evidence should be retained, and the local authority informed where required.
When to seek professional advice
A qualified arboricultural professional can:
- Assess the tree’s condition
- Identify actual risk (not just appearance)
- Recommend proportionate action
