What Is a BS5837 Tree Survey? A Clear Guide for Homeowners and Developers

Written By Nick Scally

What Is a BS5837 Tree Survey?

A BS5837 tree survey is an assessment carried out to support planning applications where trees are present on or near a development site. The survey follows the British Standard BS5837:2012 — the industry framework for how trees should be considered in relation to construction.

When Is a BS5837 Survey Required?

You’ll typically need a BS5837 survey when:

  • Building an extension

  • Creating a new dwelling

  • Developing land

  • Converting or redeveloping a site

  • Trees are close to proposed works

Local planning authorities often request BS5837 reports early in the planning process.

What the Survey Includes

A BS5837 survey records:

  • Tree species

  • Dimensions

  • Condition

  • Life expectancy

  • Root protection areas

  • Constraints to development

This information forms the basis of the Tree Constraints Plan.

AIA and AMS

If trees are affected by the proposal, you may also need:

  • AIA (Arboricultural Impact Assessment)

  • AMS (Arboricultural Method Statement)

  • Tree Protection Plan

These documents explain how trees will be protected during development.

How Long Does It Take?

Most surveys are completed within a few days, with reports delivered shortly afterwards.

Why It Matters

A clear BS5837 report helps avoid delays, objections, and costly redesigns.
