Quick answer
A tree consultant, also called an arboricultural consultant, assesses trees and provides independent technical advice. Rather than carrying out tree surgery, the consultant investigates the issue, records relevant evidence, interprets what it means and provides recommendations or a professional report for the person, lender, insurer, architect, solicitor or local authority making the decision.
The role explained
Tree consultancy is about decisions, not just trees.
A competent consultant connects what is happening on site with the decision that needs to be made.
In practice, arboricultural consultancy is much broader than identifying a tree species or deciding whether a tree looks healthy.
The consultant needs to understand why the assessment is being commissioned, what evidence is required, who will rely on the finished advice and what level of certainty can reasonably be reached.
A planning officer, mortgage lender, insurer, architect, solicitor and private tree owner may all ask questions about the same tree but require very different outputs.
The right survey starts with the right question.
A BS5837 survey is not interchangeable with a mortgage tree report, and a visual condition assessment is not automatically a specialist decay investigation.
A good tree consultant therefore defines the question, gathers appropriate evidence, interprets it professionally and communicates a clear, proportionate next step.
Roles are often confused
Tree consultant vs tree surgeon
If you need a professional opinion, technical report, planning evidence or specialist assessment, you are normally looking for consultancy rather than contracting.
| Role | Main purpose | Typical work | When you need them |
|---|---|---|---|
| Tree / arboricultural consultant | Independent professional advice | Tree surveys, technical assessment, planning reports, risk advice, diagnostics and professional evidence | When a decision needs defensible arboricultural evidence or a written professional opinion |
| Tree surgeon | Physical tree work | Pruning, dismantling, felling, planting and other practical operations | When approved or recommended tree work needs to be carried out |
| Arborist | Broad professional term | May describe someone working in practical arboriculture, consultancy or both | Check the actual role, competence and service being offered |
| Local authority tree officer | Public-sector tree and planning functions | Protected-tree matters, planning consultation and council tree management | They may assess an application but are not your privately appointed consultant |
Why independence can matter
Arbor Cultural is an arboricultural consultancy rather than a tree-surgery contractor. The consultancy does not need to sell pruning or felling work after producing its recommendations.
Common reasons for instruction
When do you need a tree consultant?
Professional arboricultural advice is commonly required where trees affect planning, property, safety, construction, protected-tree matters or a specialist technical decision.
Mortgage & Property
Where a lender, building surveyor or insurer has requested a specialist tree report.
Property reportsTree Condition & Safety
Where a professional assessment of tree condition, defects and proportionate management is needed.
Safety reportsTPOs & Conservation Areas
Where proposed work to protected trees needs the correct local-authority process and arboricultural evidence.
TPO adviceSubsidence & Roots
Where trees, roots, soil and building movement need to be considered together using evidence rather than assumption.
Subsidence adviceConstruction Near Trees
Where tree protection, method statements, monitoring or arboricultural supervision is required.
SupervisionSpecialist Diagnostics
Where visual assessment alone cannot answer the question and additional investigation may be justified.
Decay testingExpert Advice
Where a dispute, technical matter or legal instruction requires an independent specialist opinion.
Expert witness“The council says I need a tree survey for planning.”
This will often begin with a BS5837 tree survey and Tree Constraints Plan, with further documents depending on the proposal and planning stage.
Planning surveys“My lender wants a tree report.”
A mortgage or insurance tree report should be scoped specifically to the wording supplied by the lender, surveyor or insurer.
Mortgage reports“I am worried that a tree may be unsafe.”
A condition and safety assessment can consider visible condition, defects, site use and proportionate management recommendations.
Tree safety“There are cracks and trees nearby.”
This may require a subsidence-focused investigation considered alongside soil, root, structural and monitoring evidence.
Subsidence advice“The wording is unclear.”
Send the council email, lender request, planning condition or survey extract with the site address. The likely scope can be identified before quoting.

How consultancy works
From enquiry to clear professional advice
The exact commission varies, but professional arboricultural consultancy normally follows the same core stages.
Understand the question
Establish why the advice is needed and who needs to rely on it.
Define the scope
Confirm the correct survey, report or specialist investigation.
Review the context
Consider plans, site information and relevant written requirements.
Inspect the site
Record the relevant trees, site conditions and arboricultural evidence.
Analyse the evidence
Interpret what the observations mean in the context of the instruction.
Report clearly
Provide practical conclusions and proportionate recommendations.
Planning & BS5837
Tree consultancy in planning applications
BS5837 is commonly relevant where proposed development interacts with existing trees.
The initial survey records the trees and allows their constraints to be considered during design. Further arboricultural documents may then be needed depending on the proposal and planning process.
View BS5837 Tree SurveysTree Survey
Records relevant trees, groups and arboricultural characteristics.
Tree Constraints Plan
Helps the design team understand tree-related constraints at an early stage.
Arboricultural Impact Assessment
Explains how the proposed development may affect retained trees.
Tree Protection Plan
Sets out measures intended to protect retained trees during works.
Arboricultural Method Statement
Describes practical working methods where construction takes place near trees.
Choosing a consultant
What should you look for in a tree consultant?
The right choice is about more than finding someone who can identify a tree. Look at competence, relevant experience, independence and the quality of the proposed scope.
Relevant experience
The consultant should understand the type of instruction you actually have — planning, property, safety, diagnostics or another specialist matter.
Appropriate qualifications
Consider professional arboricultural qualifications, relevant training and competence for the work being commissioned.
Clear scope
You should understand what is being inspected, what the report is intended to answer and what is included in the quoted fee.
Independent advice
Consider whether the consultant has a commercial interest in selling the tree work they may recommend.
Suitable insurance
Professional consultancy should be backed by suitable professional and business insurance.
Clear communication
A strong report should make the technical evidence understandable to the person who needs to make the decision.
Consultancy fees
How much does a tree consultant cost?
There is no single meaningful price for every tree consultancy instruction because the required scope varies significantly.
The scope should come before the price.
A single-tree mortgage report, BS5837 survey of a development site, decay investigation and expert-witness instruction are fundamentally different commissions.
Arbor Cultural confirms the proposed scope and provides a fixed-fee proposal before instruction.
Site size
Larger sites generally require more survey and analysis time.
Number of trees
The number and complexity of trees can affect survey scope.
Purpose
Planning, property and safety reports have different requirements.
Plans & documents
Available drawings and supporting information can affect the work required.
Specialist testing
Additional diagnostic investigations are separate from a standard visual assessment.
Timescale
Programme and deadlines should be discussed before instruction.
Make your enquiry useful
What should you send a consultant for a quote?
You do not need to know the technical name of the report. Send the information that explains the problem and let the consultant define the appropriate scope.
1. Site address
The full location and relevant site boundary.
2. Reason for enquiry
Planning, purchase, insurance, safety, TPO or another reason.
3. Written request
Forward council, lender, surveyor or insurer wording.
4. Plans
Existing or proposed plans if they are available.
5. Photographs
Useful images can help clarify the site and trees involved.
6. Timescale
Include any planning, exchange or project deadline.
No jargon required
Paste in the wording you received.
If somebody has told you to “get a tree report” without explaining what that means, send Arbor Cultural the request exactly as it was given to you.

Frequently Asked Questions
Tree consultant FAQs
Straightforward answers to common questions before instructing an arboricultural consultant.
Is a tree consultant the same as a tree surgeon?
No. A tree consultant's main role is professional assessment and advice. A tree surgeon or arboricultural contractor carries out practical tree work such as pruning or felling.
Is an arboricultural consultant the same as a tree consultant?
In most client-facing situations, yes. Arboricultural consultant is the more technical term, while tree consultant is often used as a simpler description.
Do I always need a BS5837 tree survey for planning?
No. BS5837 is particularly relevant where development and trees interact, but not every planning application needs the same arboricultural information.
What is the difference between a tree survey and a tree report?
The survey is generally the inspection and evidence-gathering stage. The report is the written or mapped output that interprets the evidence for its intended purpose.
Can a tree consultant tell me whether a tree is dangerous?
A consultant can assess condition, visible defects, site use and relevant risk factors and provide proportionate recommendations. Some cases may require further investigation.
Do I have to be at the property during the inspection?
Not necessarily. What matters is safe and lawful access to the relevant trees and sufficient information to identify the site and instruction.
Can a consultant help after planning permission is granted?
Yes. Planning conditions may require an Arboricultural Method Statement, Tree Protection Plan, supervision, monitoring or confirmation during construction.
What if a tree is protected by a TPO?
Protected status does not necessarily mean no work can ever be carried out, but the correct local-authority process and suitable arboricultural justification may be required.
Does Arbor Cultural carry out tree surgery?
Arbor Cultural provides arboricultural consultancy rather than selling tree surgery. Where physical tree work is recommended, it can be commissioned separately from an appropriate contractor.
What is the fastest way to get an accurate quote?
Send the site address, reason for the enquiry, required timescale and any plans, photographs, council comments, lender wording or existing reports you already have.
