Mortgage & Insurance Tree Reports
Clear, defensible tree reports for lenders and insurers — focused assessments that confirm risk, condition and whether intervention is needed.
Property purchases and insurance queries often raise questions about nearby trees. A Mortgage or Insurance Tree Report provides the evidence lenders and insurers need and gives homeowners a straightforward, proportionate understanding of any real risk.
When lenders or insurers raise questions, clarity avoids delays
Concerns about tree proximity, size or potential movement can stall a mortgage offer or complicate an insurance claim.
A focused assessment shows whether the tree poses low risk, manageable risk or requires further action — keeping the process moving.
What is a Mortgage & Insurance Tree Report?
A Mortgage & Insurance Tree Report evaluates whether trees pose a risk to:
- buildings and foundations
- driveways, hard surfaces or retaining structures
- underground services
- drainage systems
- structural stability (windthrow, decay, defects)
The assessment includes:
- species, age and condition
- vitality and structural integrity
- proximity and root protection considerations
- soil behaviour (particularly shrink–swell clays)
- likelihood of tree-related damage
- proportionate recommendations
Reports are formatted for acceptance by lenders, surveyors, insurers and conveyancers.
The Mortgage & Insurance Tree Report process
| Step | Description |
|---|---|
| 1. Initial Review | Send the lender or insurer request and property details. |
| 2. Site Assessment | Inspection of the tree, its condition and its relationship to structures. |
| 3. Diagnosis | Risk classed as low, moderate or high with justification. |
| 4. Recommendations | Proportionate maintenance or monitoring guidance. |
| 5. Reporting | A lender- and insurer-ready report issued promptly. |
We keep guidance clear and planning-ready — supporting predictable project delivery.
Our Approach
Evidence Based
Clear diagnosis rooted in arboricultural and structural principles.
Measured
Recommendations aligned to real, not hypothetical, risk.
Lender & Insurance Ready
Reports structured for immediate acceptance.
Balanced Outcomes
Tree value, property safety and long-term management all considered.
Why this matters for lending and insurance
Mortgage lenders and insurers assess risk differently from planners.
They want clear evidence that a tree:
- is stable
- is unlikely to cause structural issues
- will not significantly increase risk over time
- can be managed proportionately
- does not pose foreseeable hazards
- reduce loan offers
- request further surveys
- delay approval
- impose conditions
A clear tree report keeps the process straightforward and predictable.
Do I Need this Report?
You likely need a mortgage or insurance report if:
- a homebuyer survey has flagged “tree proximity”
- your lender requests a tree report before issuing an offer
- your insurer queries the risk of subsidence or storm failure
- a neighbouring tree is raising concern
- cracks have appeared and need evidence-based explanation
- you are buying or selling a property with mature trees nearby
- the property sits on clay soil
This report provides the clarity lenders and insurers require.
What your Mortgage & Insurance Tree Report includes
A concise, defensible assessment tailored to lender and insurer expectations:
- species, age, height and crown spread
- proximity to structures and foundations
- rooting environment and soil behaviour
- vitality, defects, decay indicators and structural stability
- risk of direct or indirect damage
- realistic maintenance recommendations
- clear conclusion on risk level
- proportionate next steps
Case Note
The homebuyer report suggested “possible subsidence risk.” Assessment found no crack patterns associated with shrink–swell behaviour and no drainage defects. Species characteristics and soil indicators were reviewed, with overall risk classed as low. The lender accepted the report, and the mortgage progressed without further conditions.

Mortgage & Insurance Tree Report FAQs
What is a tree survey for mortgage or insurance purposes?
A tree survey for mortgage or insurance purposes is a professional assessment of trees on or near a property to identify potential risks to buildings, structures, or land stability. It is typically requested by lenders or insurers to confirm that trees do not pose a subsidence, structural, or safety risk that could affect the property’s value or insurability.
Why do mortgage lenders request a tree survey?
Mortgage lenders request tree surveys to assess risk. Trees located close to buildings can influence soil movement, particularly in clay soils, and may contribute to subsidence or structural damage. A survey provides evidence based conclusions so lenders can make informed decisions before approving finance.
What does a tree survey for a mortgage include?
A mortgage related tree survey typically includes:
- Identification of tree species, size, and condition
- Distance from buildings and structures
- Assessment of root influence and soil interaction
- Risk of subsidence or heave
- Structural impact on nearby buildings
- Professional recommendations, such as monitoring or management
The report is prepared in a clear, planning ready format suitable for lenders and insurers.
Can a mortgage be declined because of trees?
Yes, in some cases. If a tree presents a clear and unmanaged risk to the property, a lender may delay or decline the mortgage until further investigation or mitigation is completed. However, a professional survey often resolves uncertainty and allows the mortgage to proceed with appropriate recommendations in place.
How much does a tree survey for mortgage or insurance purposes cost?
Tree survey fees are confirmed by quotation following a brief review of the site.
Costs are based on factors such as the property location, number of trees, site size, and the level of detail required for lender or insurer reporting. We provide clear written quotations once we understand the scope of the assessment.
What influences the quotation?
Cost is primarily influenced by:
- Number of trees to be surveyed
- Site size and layout complexity
- Proximity of trees to buildings and structures
- Requirement for detailed risk or subsidence assessment
- CAD mapping or plan production, where required
- Lender or insurer reporting requirements
- Whether further investigation or specialist input is needed
Where additional services are required, such as more detailed assessments or ongoing monitoring, these are quoted separately.
How long does a tree survey take to complete?
The site inspection is usually completed within one to two hours for a typical residential property. The full report is normally issued within three to five working days, depending on complexity and whether additional data or analysis is required.
What types of trees are considered high risk for properties?
Certain tree species are more commonly associated with subsidence risk, particularly on shrinkable clay soils. These may include:
- Willow
- Poplar
- Oak
- Elm
- Ash
Risk is influenced by multiple factors, including soil type, tree size, distance from the building, and foundation depth.
Is a tree survey a legal requirement for a mortgage?
A tree survey is not a universal legal requirement. However, it may be required by a lender or insurer as part of their risk assessment process. In planning contexts, surveys may also be required by Local Planning Authorities where trees could influence development proposals.
For example, validation requirements can be reviewed via local authority guidance such as

What is the difference between a tree survey and a mortgage valuation?
A mortgage valuation is a basic assessment carried out for the lender to confirm property value. It does not provide a detailed analysis of trees or structural risk.
A tree survey is a specialist report prepared by a qualified arboricultural consultant, focusing specifically on tree related risks and recommendations.
How close can a tree be to a house before it becomes a concern?
There is no fixed rule, but as a general guide:
- Large trees within 5 to 15 metres of a property may require assessment
- The level of concern depends on species, soil type, and foundation depth
A professional survey provides site specific guidance rather than relying on generic distances.
Who carries out a tree survey for mortgage or insurance purposes?
Tree surveys are carried out by qualified arboricultural consultants with relevant experience in tree risk, subsidence assessment, and reporting for lenders and insurers. Reports are typically aligned with recognised industry standards and professional guidance.
What happens if a tree is identified as a risk?
If a risk is identified, the report will set out clear and proportionate recommendations. These may include:
- Monitoring over time
- Pruning or management
- Root barrier installation
- In some cases, removal
Recommendations are designed to satisfy lender or insurer requirements while maintaining practical and reasonable tree management.
Will removing a tree solve subsidence concerns?
Not always. In some cases, removing a tree can lead to ground heave, particularly on clay soils. A professional assessment is essential before any action is taken to ensure that the correct solution is applied.
Is a tree survey required for insurance claims involving subsidence?
Yes, insurers often require a tree survey when investigating subsidence claims. The survey helps determine whether trees are contributing to movement and supports decisions around liability, remediation, and future risk management.
How long is a tree survey valid for?
A tree survey reflects conditions at the time of inspection. For mortgage or insurance purposes, it is typically considered valid for up to 12 months, although this may vary depending on site conditions and whether any changes have occurred.
