BS5837 tree survey for planning
Do I need a BS5837 tree survey?
If a development, extension, demolition or access proposal could interact with trees on or near the site, arboricultural information may be relevant. The exact requirement depends on the project and the Local Planning Authority.
You do not need to know the acronym before you enquire.
Send the planning wording, drawings or site information you already have. Arbor Cultural can review the likely stage and scope before you instruct.
Trees may influence the layout
Tree stems are only part of the picture. Crowns, rooting areas, future growth, access, levels and construction operations can all influence a workable design.
You have been asked for “a tree report”
That wording does not always identify the exact document. Email the request or use the form above so the next step can be scoped around the real planning purpose.

What BS5837 does
Tree information that can be used by the design and planning team.
BS5837:2012 sets out recommendations for trees in relation to design, demolition and construction. The value of the survey is not simply recording trees; it is translating their characteristics and spatial relationship into useful project information.
Establish the existing tree resource
Relevant trees and groups are recorded consistently so their size, quality, condition and likely contribution can be understood.
Show the constraints spatially
Crown spreads, Root Protection Areas and the relationship between trees and the site base help the design team see where conflicts may arise.
Use the information at the right project stage
The survey can lead into an AIA, Tree Protection Plan, Method Statement or supervision where the actual proposal and planning stage require further arboricultural work.
Technical reference: BSI — Trees in relation to design, demolition and construction
What you receive
A BS5837 tree survey is more than a tree list.
Deliverables depend on the project stage and agreed scope. The aim is to give the project team the information it actually needs without automatically bundling every later-stage document.
Tree survey & schedule
Tree references, species, dimensions, condition, life stage, remaining contribution and BS5837 categorisation recorded in a structured schedule.
Tree Constraints Plan
Crown spreads, Root Protection Areas and mapped tree constraints presented against an appropriate site base.
Design-stage advice
Clear explanation of the material tree issues that may influence layout, retention, access and future tree-building relationships.
Adjacent tree consideration
Relevant trees beyond the ownership boundary can be considered where crowns, roots or construction relationships may affect the proposal.
Next-stage scope
Where AIA, TPP, AMS or supervision is likely to be relevant, the next stage can be explained separately around the actual project.
Digital project output
Agreed survey drawings and reports are prepared for practical use by the client, architect, planning consultant and wider project team.
Survey, TCP, AIA, TPP or AMS?
Different documents do different jobs.
A common source of confusion is assuming every BS5837 project needs the same package. The sequence normally moves from understanding constraints, to assessing the proposal, to protecting retained trees and controlling sensitive works where needed.

Have council wording, drawings or a planning deadline?
Use the form above or email the project information directly. The consultant can review what the project appears to need before you instruct.
What gets recorded on site?
Detailed tree data for real planning decisions.
The exact schedule depends on the scope and site, but a typical BS5837 survey records consistent characteristics so the project team can understand tree quality, size, condition and spatial influence.
Typical survey record
- Tree or group reference
- Species
- Stem diameter
- Tree height
- Crown spread
- Crown clearance
- Life stage
- Physiological condition
- Structural condition
- Estimated remaining contribution
- BS5837 category
- Preliminary management observations
How the survey affects design
The numbers matter because they can change where and how you build.
Root Protection Areas, crown dimensions, tree quality and expected future contribution are not isolated measurements. Together they help the design team understand where the strongest tree constraints sit.
Root Protection Areas
The RPA is a calculated area associated with the rooting environment that should be considered for retained trees. It helps identify where construction activity could create root risk and where design or methodology may need to respond.
Crown spread & clearance
Crown dimensions can influence building separation, windows, scaffolding, access, future pruning pressure and the long-term relationship between trees and occupants.
BS5837 retention categories
Tree categories help communicate quality and value in the development context. They are part of the evidence used when considering retention priorities and design flexibility.
- Category A — high quality and value
- Category B — moderate quality and value
- Category C — low quality and value
- Category U — unsuitable for retention in the current context
Remaining contribution & life stage
Development planning should consider not only the tree visible today but its likely future relationship with the proposal, including growth, condition, amenity and foreseeable management pressure.
Base drawings & survey control
Do I need a topographical survey first?
A professional topographical survey is normally the strongest base for development work because it gives the project team a consistent spatial reference for boundaries, levels, buildings and other site features.
Send it with the enquiry
The arboricultural information can be coordinated with the same base used by the architect and other consultants.
Manual plotting may sometimes be proportionate
For some simpler sites, Arbor Cultural can advise whether manual tree plotting is suitable or whether more precise survey control is warranted.
Reuse good project information
Architectural drawings, previous tree information, topographical surveys and council correspondence can all help establish an efficient scope.
Common BS5837 design conflicts
Trees interact with more than the building footprint.
A layout can appear clear of the trunks and still create arboricultural issues. Construction logistics and the long-term use of the finished site matter too.
Foundations & groundworks
Excavation, levels, retaining structures and foundation design can affect roots even where the visible building line appears reasonable.
Drainage & utilities
Service runs can cross rooting areas or require excavation in constrained parts of a site, making early coordination valuable.
Access & hard surfaces
Driveways, parking, temporary access and construction traffic can create rooting-area or soil-compaction issues.
Demolition & logistics
Demolition routes, storage, welfare, plant movement and material handling may need tree protection controls before the new build starts.
Scaffolding & working space
A building may fit on plan but still need construction access beneath crowns or within rooting constraints.
Future amenity pressure
Very close tree-building relationships can create future pressure for pruning or removal because of shade, leaf fall, proximity or perceived risk.
BS5837 tree survey cost
A useful quote starts with the scope, not a teaser price.
A small domestic plot is different from a constrained redevelopment with extensive tree stock, multiple drawings and several planning deliverables. Arbor Cultural can provide a fixed-fee proposal once the required work has been reviewed.
Practical scope variables
- Number, density and complexity of trees
- Site size, access and travel
- Availability and quality of base drawings
- Relevant neighbouring trees
- Planning stage and documents required
- Complexity of the design and tree relationships
- Genuine deadline or sequencing constraints

What happens after you enquire?
From enquiry to professional scope in four clear steps.
The first objective is to understand the site, the planning stage and what the project actually needs. The professional work follows once the scope is agreed.
Email or complete the form above
Add council wording, drawings, a previous report or photographs if you have them. Incomplete information is fine for the first step.
Consultant reviews the likely requirement
The relevant BS5837 stage, information gaps and the scope needed to price the work can be identified.
Review the fixed-fee proposal
You can see the professional scope and fee before instruction. Requesting a proposal does not commit you to proceed.
Survey, reporting & next step
The agreed work is completed and issued digitally. If another planning stage is relevant, the next step can be explained clearly.
Independent arboricultural consultancy
Professional judgement for different project teams.
The underlying tree information may be similar, but the reason for commissioning it differs. Advice should make sense to the person using it, whether that is a homeowner, architect, developer or planning consultant.
Clear explanation without the acronyms
Understand what the council or architect appears to need without being expected to identify the technical report title first.
Tree constraints that can inform design
Survey information and spatial constraints can be coordinated with the design process, with a route into AIA, TPP and AMS work where relevant.
Proportionate scope and continuity
Professional arboricultural input can continue through later planning and construction stages where the project requires it.
Technical input around planning wording
Project information can be reviewed against Local Planning Authority requests and the appropriate arboricultural stage.

BS5837 tree surveys across London & the South East
Planning tree surveys across London, Surrey and the wider South East.
Arbor Cultural supports planning and development work across Greater London, Surrey, West Sussex, East Sussex, Kent, Hampshire, Berkshire, Buckinghamshire and Oxfordshire. Local validation requirements, tree policies and supporting-document expectations can vary, so the scope is reviewed around the actual site, proposal and planning stage.
Urban infill, extensions & redevelopment
Dense sites, neighbouring trees, basement proposals, constrained access and close tree-building relationships can make early arboricultural information especially useful.
Suburban, village & Green Belt sites
Garden trees, mature boundaries, neighbouring trees, access changes and protected-tree context commonly influence residential and development proposals.
Residential & mixed development
From Crawley and Horsham to Chichester and Worthing, tree constraints can interact with layout, access, drainage, levels and construction logistics.
Coastal, urban & rural planning sites
Brighton, Hove, Lewes, Eastbourne and surrounding areas can involve varied site conditions, sloping ground, retained trees and sensitive neighbouring relationships.
Town, village & edge-of-settlement projects
Planning work can range from domestic extensions and replacement dwellings to larger schemes where tree retention, access and mitigation need early consideration.
Planning from commuter towns to the south coast
Sites around Basingstoke, Winchester, Portsmouth, Southampton, Petersfield and the wider county can require proportionate BS5837 input through design and construction stages.
Residential & development sites
Ascot, Windsor, Maidenhead, Reading, Wokingham and surrounding areas often combine mature trees with constrained plots, redevelopment pressure and complex layouts.
Village, suburban & larger proposals
Tree constraints can influence design, access and construction methodology from Beaconsfield and Gerrards Cross through to Aylesbury and Milton Keynes.
Urban, village & edge-of-town development
From Oxford and Abingdon to Henley, Witney and Banbury, early tree information can help project teams understand retention and spatial constraints before design is fixed.
Planning requirements are local; the underlying BS5837 principles remain consistent.
Different planning authorities can have different validation checklists, policies and expectations for arboricultural information. Send any wording already issued for the site and Arbor Cultural can help identify whether the project appears to need a survey, Tree Constraints Plan, Arboricultural Impact Assessment, Tree Protection Plan, Arboricultural Method Statement or later supervision.

BS5837 questions
Answers before you instruct.
If your question depends on something the council, architect or planning consultant has written, email that wording or attach it through the form above rather than guessing which report title applies.
What is a BS5837 tree survey?
BS5837:2012 provides recommendations for considering trees in relation to design, demolition and construction. A survey records relevant trees and their characteristics so tree constraints can be understood and taken into account during the development process.
Do I need a BS5837 survey before submitting a planning application?
Where trees on or near the site may be relevant to a proposal, obtaining arboricultural information early can help the design team understand constraints before the layout is fixed. The exact requirement depends on the site, proposal and Local Planning Authority.
Can neighbouring trees need to be included?
Yes. Trees outside the ownership boundary may still be relevant where crowns, roots or Root Protection Areas could interact with the proposed development or construction activity. Access and available information can affect how off-site trees are recorded.
What is a Tree Constraints Plan?
A Tree Constraints Plan normally plots relevant trees, crown spreads, Root Protection Areas and other tree-related constraints against a suitable site base so the design team can understand how trees may influence the emerging layout.
What is the difference between a BS5837 survey, AIA, TPP and AMS?
The survey establishes the relevant tree information and constraints. An Arboricultural Impact Assessment considers the specific proposal, a Tree Protection Plan shows protection measures, and an Arboricultural Method Statement sets out methodology for sensitive operations where required.
Do I need a topographical survey first?
A suitable topographical survey is normally the strongest base for development work. For some smaller or simpler sites without one, Arbor Cultural can advise whether proportionate manual tree plotting is suitable or whether more precise survey control is needed.
What affects the cost of a BS5837 tree survey?
Typical variables include site size, tree numbers and complexity, access, travel, the quality of available base drawings, whether neighbouring trees need to be considered, the planning stage and the documents required. Arbor Cultural can provide a fixed-fee proposal once the scope has been reviewed.
What should I send with my enquiry?
Send whatever already exists: planning or council wording, architectural drawings, a topographical survey, previous tree reports, site photographs, the planning reference and any genuine project deadline. You do not need a perfect information pack to start.
Will the council accept the report?
The purpose is to provide professional arboricultural information appropriate to the relevant BS5837 planning stage and Local Planning Authority review. No consultant controls a planning decision, so the focus is on correct scope, clear evidence and professional advice.
Can Arbor Cultural help after planning permission?
Yes. Depending on the approved documents and planning conditions, later stages can include Tree Protection Plans, Arboricultural Method Statements, pre-commencement information, condition discharge support or arboricultural supervision during sensitive works.
Do planning requirements vary across London and the South East?
Yes. Local validation requirements, tree policies and supporting-document expectations can vary between planning authorities. The correct scope should therefore be based on the site, proposal, current planning stage and any authority wording already issued.
Do all planning authorities ask for the same BS5837 documents?
No. The appropriate arboricultural information depends on the site, proposal and the relevant authority's current validation or planning requirements. A baseline BS5837 survey may lead to an AIA, Tree Protection Plan, Arboricultural Method Statement or later supervision where the project requires those stages.
Do you cover smaller towns and villages as well as the main South East cities?
Yes. Arbor Cultural's coverage includes smaller towns and villages as well as larger urban areas across London and the wider South East. The regional dropdowns on this page show the named areas represented in the current service coverage.
