A BS5837:2012 tree survey records the relevant trees on or adjacent to a development site so their condition, quality, crown spread and Root Protection Areas can be considered during design, demolition and construction. The survey normally informs a Tree Constraints Plan and may lead to an Arboricultural Impact Assessment, Tree Protection Plan or Arboricultural Method Statement once the project design and planning stage are known.
Especially where trees on or beside the site could influence an extension, redevelopment, demolition, access or construction work.
Species, dimensions, crown spread, condition, life stage, remaining contribution and other relevant survey information.
A Tree Constraints Plan helps architects and project teams see the spatial relationship between trees and the emerging design.
We review the project first, then provide a fixed-fee proposal based on the work actually required.
Use the quote form above, or email the documents you already have. You do not need to identify every BS5837 document before getting in touch.
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.

A BS5837 survey can establish the tree information and spatial constraints that should be considered during design and planning.
Tree stems are only part of the picture. Crowns, rooting areas, future growth, access, levels and construction operations can all influence a workable design.
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.
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.
Relevant trees and groups are recorded consistently so their size, quality, condition and likely contribution can be understood.
Crown spreads, Root Protection Areas and the relationship between trees and the site base help the design team see where conflicts may arise.
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.

Crown spreads, Root Protection Areas and mapped tree constraints presented against an appropriate site base.
Clear explanation of the material tree issues that may influence layout, retention, access and future tree-building relationships.
Relevant trees beyond the ownership boundary can be considered where crowns, roots or construction relationships may affect the proposal.
Where AIA, TPP, AMS or supervision is likely to be relevant, the next stage can be explained separately around the actual project.
The survey schedule and agreed survey drawings are prepared for practical use by the client, architect, planning consultant and wider project team.
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.

A BS5837 survey schedule records consistent tree information so the design and planning team can understand tree quality, size, condition, future contribution and spatial influence before the layout is fixed.
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.
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 dimensions can influence building separation, windows, scaffolding, access, future pruning pressure and the long-term relationship between trees and occupants.
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.
Our guide to BS5837 tree categories A, B, C and U explains how the categories inform planning and design.
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.
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.
The arboricultural information can be coordinated with the same base used by the architect and other consultants.
For some simpler sites, Arbor Cultural can advise whether manual tree plotting is suitable or whether more precise survey control is warranted.
Architectural drawings, previous tree information, topographical surveys and council correspondence can all help establish an efficient scope.
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.
Excavation, levels, retaining structures and foundation design can affect roots even where the visible building line appears reasonable.
Service runs can cross rooting areas or require excavation in constrained parts of a site, making early coordination valuable.
Driveways, parking, temporary access and construction traffic can create rooting-area or soil-compaction issues.
Demolition routes, storage, welfare, plant movement and material handling may need tree protection controls before the new build starts.
A building may fit on plan but still need construction access beneath crowns or within rooting constraints.
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 costs depend on the number and complexity of trees, site size and access, available drawings, travel, neighbouring-tree considerations and the survey mapping required. Arbor Cultural reviews the actual survey scope first and provides a fixed-fee proposal before instruction.
Why no one-size-fits-all headline price? A small domestic plot with a handful of trees is materially different from a larger or constrained development site. The quote is based on the survey work the site actually requires rather than a teaser price.
You do not need a perfect information pack. Existing project material can help a consultant identify what is already known and what may still be needed.
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.
Add council wording, drawings, a previous report or photographs if you have them. Incomplete information is fine for the first step.
The relevant BS5837 stage, information gaps and the scope needed to price the work can be identified.
You can see the professional scope and fee before instruction. Requesting a proposal does not commit you to proceed.
The agreed survey work is completed and issued digitally. If the project later needs an AIA, TPP, AMS or supervision, that next stage can be scoped separately.
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.
Understand what the council or architect appears to need without being expected to identify the technical report title first.
Survey information and spatial constraints can be coordinated with the design process, with a route into AIA, TPP and AMS work where relevant.
Professional arboricultural input can continue through later planning and construction stages where the project requires it.
Project information can be reviewed against Local Planning Authority requests and the appropriate arboricultural stage.

Live Trustindex feedback from clients who have instructed Arbor Cultural for tree surveys, planning reports and wider arboricultural consultancy.
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.
Dense sites, neighbouring trees, basement proposals, constrained access and close tree-building relationships can make early arboricultural information especially useful.
Garden trees, mature boundaries, neighbouring trees, access changes and protected-tree context commonly influence residential and development proposals.
From Crawley and Horsham to Chichester and Worthing, tree constraints can interact with layout, access, drainage, levels and construction logistics.
Brighton, Hove, Lewes, Eastbourne and surrounding areas can involve varied site conditions, sloping ground, retained trees and sensitive neighbouring relationships.
Planning work can range from domestic extensions and replacement dwellings to larger schemes where tree retention, access and mitigation need early consideration.
Sites around Basingstoke, Winchester, Portsmouth, Southampton, Petersfield and the wider county can require proportionate BS5837 input through design and construction stages.
Ascot, Windsor, Maidenhead, Reading, Wokingham and surrounding areas often combine mature trees with constrained plots, redevelopment pressure and complex layouts.
Tree constraints can influence design, access and construction methodology from Beaconsfield and Gerrards Cross through to Aylesbury and Milton Keynes.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
The survey is prepared to provide professional arboricultural information appropriate to the relevant BS5837 planning stage and Local Planning Authority review. No consultant can control a planning decision, so the focus is on correct scope, clear survey evidence and professional advice.
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.
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.
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.
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.
Send the information you already have. Arbor Cultural can review the likely arboricultural stage and provide the appropriate proposal before instruction.
