Tree Damage Survey
Focused assessments to confirm whether trees are causing structural, surface or drainage damage — clear evidence, measured solutions and stable decision-making.
Damage around trees often appears suddenly: lifting surfaces, cracked walls, displaced paving or recurring drainage issues. A Tree Damage Survey identifies whether the tree is directly involved, indirectly contributing, or simply nearby.
When damage appears, assumptions aren’t enough...
Tree-related damage is frequently misunderstood. Some symptoms look significant but are unrelated; others reveal a genuine structural interaction. A clear assessment distinguishes cosmetic issues from real risk, helping you avoid unnecessary works or delays.
What is a Tree Damage Survey?
A Tree Damage Survey investigates whether a tree is contributing to structural, surface or drainage damage by assessing:
- root pathways and physical root pressure
- proximity, species and growth characteristics
- soil behaviour and local ground conditions
- cracks, displacement and surface lifting
- drainage conflicts and root ingress
- structural context and load distribution
The assessment provides a clear conclusion on whether tree influence is:
confirmed, possible, or unlikely.
Reports are suitable for planning, structural investigations, insurance queries and contractor guidance.
Do I need a Tree Damage Survey?
You may need a tree damage survey if you’ve seen:
- lifting or cracked driveways or paths
- displaced retaining walls
- recurring damage to hard landscaping
- roots emerging at the surface
- drainage blockages or infiltration
- cracks appearing near trees or hedgerows
- damage raised by surveyors, planners or insurers
A Tree Damage Survey identifies the cause and sets out proportionate next steps.
Why this matters for planning
Trees fall under planning legislation as material considerations.
When damage occurs, LPAs require reliable evidence to determine:
- whether a tree is genuinely causing harm
- whether removal or pruning is justified
- whether designs need modification
- whether conditions should be applied
Without clear reporting, applications may stall, trigger further questions or require design changes.
A Tree Damage Survey includes:
A clear, practical and defensible assessment:
- on-site inspection of damage type and extent
- species identification and growth characteristics
- proximity assessment and root pathway analysis
- evaluation of soil behaviour and ground conditions
- cracking and displacement interpretation
- drainage interaction checks (where relevant)
- assessment of tree involvement: likely / possible / unlikely
- proportionate recommendations
- guidance for planning, engineering or contractor work

Case Note
Surface displacement suggested possible root pressure. Assessment confirmed shallow, fibrous roots directly beneath the paving, with no structural impact to the house. The issue was classed as a surface-level conflict. Localised root pruning and correct reinstatement of the driveway resolved the problem without tree removal.
Tree Damage Survey FAQs
What is a Tree Damage Survey?
A Tree Damage Survey is a specialist arboricultural assessment used to investigate whether trees are causing structural damage to buildings, walls, drives, or other built assets. It provides clear, evidence based conclusions on causation, supported by site inspection, tree data, and where required, soil and foundation analysis.
When is a Tree Damage Survey required?
A Tree Damage Survey is typically required when there are signs of structural movement such as cracking, subsidence, or heave, and trees are present nearby. It is often requested by homeowners, insurers, loss adjusters, or solicitors to establish whether vegetation is contributing to the issue.
What types of damage can trees cause to property?
Trees can contribute to subsidence by extracting moisture from shrinkable clay soils, leading to ground movement. In some cases, direct damage can occur through root growth affecting drains, paving, or shallow foundations. A professional survey determines whether the tree is a contributing factor or not.
How do you prove a tree is causing subsidence?
Proving causation requires a combination of arboricultural assessment and supporting evidence. This may include tree species identification, distance from the structure, soil type, seasonal movement patterns, and in some cases laboratory soil testing or root identification. A Tree Damage Survey brings this evidence together into a defensible conclusion.
Who is responsible if a tree damages a property?
Responsibility depends on ownership and whether negligence can be demonstrated. If a tree owner has been made aware of a risk and failed to act reasonably, liability may arise. A Tree Damage Survey provides the technical evidence needed to support or defend a claim.
Can I force a neighbour to remove a tree causing damage?
You cannot automatically force removal, but if damage is proven and liability established, legal action may be taken. In many cases, issues are resolved through insurance claims or professional negotiation supported by survey evidence.
Is a Tree Damage Survey needed for insurance claims?
Yes, insurers often require a professional Tree Damage Survey to confirm causation before accepting or rejecting a subsidence claim. The report provides the technical justification needed to support decisions on liability and remedial action.
How much does a Tree Damage Survey cost?
Costs vary depending on the complexity of the case, number of trees, and level of investigation required. As a guide, straightforward assessments typically start from around £495 plus VAT, with more detailed investigations quoted individually where specialist testing or monitoring is needed.
What does a Tree Damage Survey include?
A typical Tree Damage Survey includes a site inspection, tree identification and measurement, assessment of distance and influence, review of visible damage, and a clear professional opinion on causation. Where required, recommendations for further investigation or management are also provided.
Is a Tree Damage Survey a legal document?
Yes, Tree Damage Surveys are often used in legal and insurance contexts. Reports can be prepared in line with Part 35 of the Civil Procedure Rules where required, making them suitable for dispute resolution and expert witness use.
How long does a Tree Damage Survey take?
Site inspections are usually completed within a few hours depending on site size and complexity. The full report is typically issued within a few working days, although more complex cases involving testing or third party data may take longer.
Can a Tree Damage Survey support planning or tree removal applications?
Yes, where damage is proven, the survey can support applications for tree works, including works to protected trees. Applications must be submitted to the relevant Local Planning Authority, such as:

What happens if the tree is not the cause of damage?
If the tree is not responsible, the report will clearly state this and may identify alternative causes such as drainage defects, construction issues, or natural settlement. This ensures decisions are based on evidence rather than assumption.
Do all cracks in buildings mean tree related subsidence?
No. Cracking can occur for many reasons, including thermal movement, settlement, or structural defects. A Tree Damage Survey ensures that trees are only implicated where there is clear supporting evidence.
Can multiple trees contribute to damage?
Yes, in some cases more than one tree may influence soil moisture levels and contribute to movement. The survey assesses the combined impact of all relevant vegetation to provide an accurate conclusion.
