Do you need a Tree Survey for Planning in Kent?
If trees sit on or near your site in Kent, your planning application is highly likely to require a BS 5837 Tree Survey. Root protection areas, crown spread, access positioning and tree quality all influence whether a layout is acceptable. Without early arboricultural evidence, even small schemes can trigger validation delays, redesign requests or restrictive conditions.
We confirm what’s required quickly and proportionately so your application stays on track.
Across Kent, tree constraints frequently influence planning where development meets established suburban and semi-rural environments.
This commonly includes:
Residential areas with mature garden canopies, where extensions are constrained
Edge-of-settlement sites, where retained trees influence layout and access
Redevelopment land, where historic planting remains material
Semi-rural plots, where tree groups sit within influence distance of foundations
Kent planning officers routinely test whether layouts have been shaped by retained trees from the outset.
We undertake Tree Surveys for Planning across Maidstone, Canterbury, Ashford and surrounding areas, supporting residential and commercial development throughout Kent.
Why Planning Authorities Require a Tree Survey in Kent
Kent planning authorities rely on clear arboricultural evidence to assess whether development layouts properly respond to existing trees. Trees are a material planning consideration under the Town and Country Planning Act 1990, with national policy reinforced through the NPPF and technical requirements set out in BS 5837 (Trees in relation to design, demolition and construction). Where proposals affect root protection areas, canopy spread or retained tree quality, planners must be satisfied that designs are feasible, proportionate and deliverable.
When arboricultural evidence is unclear or incomplete, applications are commonly delayed, conditioned or returned for revision.

FAQ - Tree Surveys for Planning in Kent
Why might a BS 5837 tree survey be needed for planning in Kent?
A BS 5837 tree survey may be needed where trees are present on or close to a proposed development site in Kent. This can include residential developments, replacement dwellings, extensions, agricultural projects, commercial schemes, and redevelopment sites. The survey helps identify tree related constraints early so they can be considered before a planning application is submitted.
What information does a BS 5837 tree survey provide?
A BS 5837 tree survey records the species, height, stem diameter, canopy spread, age class, condition, and retention category of relevant trees. It also calculates Root Protection Areas (RPAs) and identifies constraints that may affect site layout, foundations, drainage design, access arrangements, utility installations, and construction activities.
Can trees within orchards or established landscapes affect development proposals?
Yes. Kent contains many sites with mature trees, historic landscapes, and orchard planting that may influence development proposals. Trees can affect building positions, access routes, drainage infrastructure, and construction methods. A BS 5837 survey helps identify these constraints and informs the design process before plans are finalised.
Why should a tree survey be completed before detailed designs are prepared?
Undertaking a tree survey early allows the design team to understand tree constraints before committing to a layout. This can reduce the risk of planning objections, requests for additional information, or costly redesign work later in the planning process.
What is a Root Protection Area and why is it important?
A Root Protection Area is the minimum area surrounding a tree that should remain protected to help maintain its health and stability. Development within an RPA can damage roots and compromise the long term viability of a retained tree. BS 5837 surveys calculate RPAs and show them on plans to guide design and construction decisions.
Do neighbouring trees need to be included in a BS 5837 survey?
Yes. Trees located outside the site boundary may still need to be assessed if their canopies or Root Protection Areas extend into the development site. These trees can influence foundation design, excavation works, access arrangements, and construction methodology, making them relevant to the planning assessment.
Are Tree Preservation Orders important for developments in Kent?
Yes. Trees protected by a Tree Preservation Order (TPO) or located within a Conservation Area can significantly influence development proposals. A BS 5837 survey helps identify protected trees and assess how the proposed development may affect them, allowing appropriate mitigation and protection measures to be incorporated into the design.
Which planning authority may request a BS 5837 tree survey in Kent?
Requirements vary depending on whether the site falls within Kent County Council’s planning functions or a district authority such as Ashford, Canterbury, Dartford, Maidstone, Sevenoaks, Swale, Thanet, Tonbridge and Malling, or Tunbridge Wells. Kent County Council provides planning guidance here: https://www.kent.gov.uk/about-the-council/strategies-and-policies/planning-policies. Applicants should review the requirements of the relevant planning authority before submitting an application.
Can a BS 5837 tree survey help avoid planning delays?
Yes. Providing arboricultural information at an early stage helps planning officers understand how a development may affect existing trees. This can reduce requests for additional information, support smoother validation, and minimise delays during the planning determination process.
What documents may be required after a BS 5837 tree survey?
Depending on the proposal, additional documents may include a Tree Constraints Plan, Arboricultural Impact Assessment (AIA), Tree Protection Plan (TPP), and Arboricultural Method Statement (AMS). These documents explain how trees influence the development and set out the measures required to protect retained trees before, during, and after construction.
