What is a BS 5837 Tree Survey?

BS 5837:2012 is the British Standard that sets out how trees near development sites should be surveyed, assessed and managed. Local planning authorities across Hampshire require a BS 5837 survey as part of most planning applications where trees are present.

What the survey covers

  • Individual tree survey data — species, height, crown spread, condition grade
  • Category assessment (A, B, C or U) based on the tree’s quality and life expectancy
  • Root Protection Area (RPA) calculations for each tree
  • Constraint mapping — showing how trees affect the developable area
  • Tree Retention and Removal Schedule
  • Tree Protection Plan (TPP) — drawings showing protection measures during construction
  • Arboricultural Method Statement (AMS) — how tree protection will be implemented on site

When you need one

  • Any planning application where trees are present on or adjacent to the site
  • Pre-application discussions with a local planning authority
  • Where a planning condition requires an AMS before development commences
  • Property purchase — understanding tree constraints before you commit
  • Where trees need to be removed or pruned as enabling works for construction
  • Discharge of planning conditions relating to trees

Reports We Produce

We produce the full suite of arboricultural documents required to support planning applications and discharge conditions.

📊

BS 5837 Tree Survey Report

Full individual tree assessment to BS 5837:2012, with category grades, dimensions, condition notes and constraint data. Includes survey register in the format required by Hampshire LPAs.

🗺️

Tree Protection Plan

Scaled drawing showing tree positions, RPAs, proposed development footprint and exclusion zone fencing. Submitted with the planning application and used by contractors on site.

📋

Arboricultural Method Statement

Written specification for how trees will be protected during construction — fencing specification, working methods within RPAs, supervision requirements. Required for planning condition discharge.

📝

Arboricultural Impact Assessment

Assessment of the impact of a proposed development on existing trees — typically required for larger schemes or where tree constraints are likely to influence the design.

🔍

Tree Health & Condition Reports

For insurance, property purchase or single-tree concerns — see our tree health survey page for non-planning health reports.

👷

Arboricultural Supervision

On-site supervision of works within RPAs, with a written watching brief record. Required by some planning conditions to confirm tree protection was implemented as specified.

Frequently Asked Questions

Usually yes, if there are trees on or adjacent to your site. Winchester City Council, Test Valley Borough Council, Eastleigh Borough Council and other Hampshire LPAs all require a BS 5837 survey where trees could be affected by development. We’ll advise you on the specific documents required for your application once we’ve reviewed the site.

The site survey typically takes a few hours depending on the number of trees. The written report is usually ready within 5–7 working days. If you have a planning submission deadline, tell us when you contact us and we’ll work to your programme.

Yes — this is one of the advantages of working with us. We produce the survey and reports in-house, then carry out any required enabling tree works ourselves. There’s no need to manage a separate arboricultural consultant and a separate contractor. See our property developers page for more on how we work with development teams.

A BS 5837 survey is specifically structured for planning purposes — it categorises trees, calculates Root Protection Areas and produces documents for planning submission. A tree health survey is a broader assessment of a tree’s health, condition and any risks it poses, used for insurance, property purchase or management decisions rather than planning.
