Do you need a Tree Survey for Planning in Hampshire?
If trees sit on or near your site in Hampshire, 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 Hampshire, tree constraints most often influence planning where development occurs within well-treed suburban and semi-rural settings.
This commonly includes:
Established residential areas, where mature garden trees affect extensions and basements
Edge-of-settlement growth, where retained trees shape access and layout
Previously developed land, where long-established planting is expected to be assessed
Semi-rural plots, where tree groups fall within root protection areas
Hampshire planning authorities expect tree constraints to be resolved through design-led solutions.
We undertake Tree Surveys for Planning across Winchester, Southampton, Basingstoke and surrounding settlements, supporting residential and commercial development throughout Hampshire.
Why Planning Authorities Require a Tree Survey in Hampshire
Hampshire 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 Hampshire
Why might a BS 5837 tree survey be needed for planning in Hampshire?
A BS 5837 tree survey may be needed where trees are present on or close to a proposed development site in Hampshire. This can include householder extensions, replacement dwellings, garden plots, access changes, rural conversions, and commercial schemes. The survey identifies tree constraints early so they can be considered before plans are submitted.
What does a tree survey for planning assess?
A tree survey for planning assesses the species, height, stem diameter, canopy spread, age class, condition, and retention category of relevant trees. It also calculates Root Protection Areas and identifies constraints that may influence building positions, drainage, service routes, access, foundations, and construction activity.
Can trees close to woodland edges affect a Hampshire planning application?
Yes. Trees close to woodland edges, site boundaries, or neighbouring land can affect a planning application if their canopies or Root Protection Areas extend into the proposed works area. A BS 5837 survey helps determine how these trees may influence layout, excavation, access, and construction methods.
Why should a tree survey be carried out before the design is finalised?
Carrying out a tree survey before the design is finalised allows tree constraints to inform the layout from the start. This can help avoid redesign, reduce planning delays, and support a more robust submission where retained trees and Root Protection Areas have been properly considered.
What is a Root Protection Area in a BS 5837 survey?
A Root Protection Area is the minimum area around a tree that should be protected to maintain its health and stability. BS 5837 surveys calculate Root Protection Areas for retained trees and show them on plans so buildings, driveways, drainage, and services can be designed around important root zones.
Are neighbouring trees included in a Hampshire BS 5837 survey?
Neighbouring trees should be included where they could influence the proposed development. Even if trees are outside the site boundary, their canopies or Root Protection Areas may extend into the works area, making them relevant to excavation, construction access, ground protection, and planning assessment.
Are Tree Preservation Orders important for Hampshire developments?
Yes. Trees protected by a Tree Preservation Order or located within a Conservation Area may affect what works are permitted and what supporting information is required. A BS 5837 tree survey helps identify protected or important trees and supports a planning submission that considers tree retention and protection properly.
Which planning authority may request a BS 5837 tree survey in Hampshire?
Requirements vary depending on whether the site falls within Hampshire County Council, Winchester, East Hampshire, Basingstoke and Deane, Test Valley, New Forest, Fareham, Gosport, Havant, Rushmoor, Hart, or a unitary authority such as Portsmouth or Southampton. Hampshire County Council provides planning guidance here: https://www.hants.gov.uk/landplanningandenvironment/planning. Applicants should check the relevant local authority requirements before submitting.
What happens if tree constraints are not addressed in a planning application?
If tree constraints are not addressed where trees could be affected, the local planning authority may request further arboricultural information before determining the application. This can delay validation, extend assessment timescales, or require changes to the layout, access, drainage, or construction methodology.
What documents may be required after a BS 5837 tree survey?
Depending on the site and proposal, further documents may include a Tree Constraints Plan, Arboricultural Impact Assessment, Tree Protection Plan, and Arboricultural Method Statement. These documents explain how trees influence the development and how retained trees will be protected before and during construction.
