What Is a Tree Condition Report?

 

A tree condition report is a vital document used to assess the health, structural integrity, and overall safety of individual trees. It plays a crucial role in responsible tree management, ensuring property owners meet their legal obligations while promoting the preservation of healthy trees.

This guide explains what a tree condition report involves, when you might need one, what it typically includes, and why it’s essential for landowners, councils, and developers.

What Is a Tree Condition Report?

Understanding the Purpose of a Tree Condition Report

A tree condition report provides a professional evaluation of a tree’s current health and structural condition. It identifies defects, diseases, or risks, and offers clear management recommendations.

Such reports are commonly used to:

  • Manage tree safety near buildings, roads, and public spaces 
  • Support planning applications and development projects 
  • Assist with Tree Preservation Order (TPO) applications 
  • Meet insurance requirements 
  • Mitigate liability risks under UK civil and criminal law

Legal Duty of Care

In the UK, landowners have a duty of care under common law to prevent reasonably foreseeable risks from trees to people and property. Failure to inspect and maintain trees properly can lead to costly legal action.

A professional tree condition report provides written evidence that reasonable steps have been taken to manage tree risks.

When Should You Commission a Tree Condition Report?

Tree condition reports may be required in several situations:

After Severe Weather Events

Storms, strong winds, and heavy snow can cause hidden structural damage. A report will assess any impact and recommend necessary actions.

Before Property Development

Planning departments often require a tree report to understand how construction may affect nearby trees, especially those protected by TPOs or located in conservation areas.

Following Signs of Poor Tree Health

If a tree shows signs of decay, dieback, fungal infection, or unusual growth patterns, a condition report can diagnose the problem.

Routine Tree Management

Large estates, councils, schools, and commercial sites often schedule periodic tree surveys as part of proactive risk management.

What Is Included in a Tree Condition Report?

Each tree is recorded with its:

  • Species (common and botanical name) 
  • Size (height and trunk diameter) 
  • Location (described with maps or photographs) 
  • Condition (visual appearance, vitality, and defects)

Visual Tree Assessment (VTA)

The first step usually involves a Visual Tree Assessment (VTA). Arborists examine:

  • Surface roots 
  • Trunk condition (e.g., cavities, cracks, fungal fruiting bodies) 
  • Branch structure 
  • Crown density and shape 
  • Leaf health and bud development 

Advanced Testing (If Required)

When external signs raise concern, further diagnostic tools are used:

  • Sonic Tomography: Tests internal decay by measuring sound wave speeds through the wood 
  • Resistograph Drilling: Uses a fine needle to detect variations in wood density 
  • Soil testing: Assesses root zone health and stability

Risk Assessment

The surveyor evaluates:

  • Likelihood of tree or branch failure 
  • Potential target zones (e.g., highways, footpaths, buildings) 
  • Overall risk level based on the tree’s health and position

Management Recommendations

Based on findings, the report may recommend:

  • Pruning 
  • Crown reduction 
  • Monitoring and reinspection schedules 
  • Bracing 
  • Tree removal (if risk is unmanageable)

Legal and Safety Considerations

Good reports reference relevant legislation, such as:

Who Can Produce a Tree Condition Report?

Tree condition reports should only be carried out by qualified, experienced professionals, such as:

The surveyor’s qualifications and experience ensure accurate assessments and defensible legal documentation.

Benefits of a Tree Condition Report

A tree condition report is a valuable investment for several reasons:

Legal Protection

Documented inspections help demonstrate that a landowner has taken reasonable steps to manage tree risks responsibly.

Documented inspections help demonstrate that a landowner has taken reasonable steps to manage tree risks responsibly.

Risk Reduction

Identifying and addressing potential hazards reduces the risk of injury, property damage, and costly insurance claims.

Tree Preservation

Early detection of diseases or structural issues enables appropriate intervention, helping to extend the life of valuable trees.

Financial Planning

Knowing a tree’s condition allows landowners to plan maintenance or removal costs and avoid expensive emergency works.

How Much Does a Tree Condition Report Cost?

Costs vary depending on the number of trees assessed, site access, and whether specialist equipment (e.g., tomography) is required.

  • Basic Visual Survey: £150–£400 
  • Detailed Diagnostic Survey (including tomography) : £500–£1,500 or more

It’s essential to ensure that any report is detailed enough to withstand legal or planning scrutiny.
