BS5837 Tree Survey for Planning Applications in the UK

When planning a new development, whether it’s a residential extension or a large-scale commercial project, trees on or near the site can significantly influence your planning application. A BS5837 Tree Survey is a crucial step in identifying and managing the impact of existing trees on development proposals.

What is a BS5837 Tree Survey?

BS5837 refers to the British Standard 5837:2012, titled "Trees in relation to design, demolition and construction – Recommendations." This standard outlines how trees should be considered in the planning process to ensure that valuable trees are retained and protected during development.

A BS5837 Tree Survey assesses all trees on or near a proposed development site. It provides detailed information, including:

• Tree species, age, and condition

• Root Protection Areas (RPAs)

• Tree categorisation (A, B, C, U grading system)

• Recommendations for retention, removal, or protection

• Impact of development on trees and vice versa

  
  

This data forms the basis for informed planning decisions that balance development needs with environmental responsibility.

Why is a BS5837 Survey Important for Planning?

Local Planning Authorities (LPAs) require a BS5837 Tree Survey to determine how trees will be affected by proposed works. In fact, submitting a planning application without one where trees are present can lead to delays or rejections.

The survey helps:

• Identify constraints to development posed by existing trees

• Prevent damage to valuable trees during construction

• Comply with UK planning regulations and tree protection laws

• Support Biodiversity Net Gain and sustainable development goals

When is a BS5837 Tree Survey Required?

You’ll likely need a BS5837 Tree Survey if:

• There are trees on or near the boundary of your site

• The project involves demolition or groundworks

• Your planning authority specifically requests it

• Trees are subject to Tree Preservation Orders (TPOs) or are within a Conservation Area

  
  

Whether you're submitting an outline or full planning application, conducting the survey early helps avoid costly delays.

What Does a BS5837 Tree Survey Involve?

At Elite Ecology, we follow a structured and compliant approach to BS5837 Tree Surveys:

1. Site Visit and Tree Assessment

Our qualified arboriculturists visit your site to record key information about each tree, group of trees, or hedgerow.

2. Categorisation and Mapping

Each tree is graded from A (high quality) to U (unsuitable for retention) and plotted on a Tree Constraints Plan using GPS/GIS technology.

3. Root Protection Area Calculation

We calculate RPAs to guide where construction activities can safely take place without harming tree roots.

4. Recommendations and Reporting

We produce a comprehensive report with guidance on which trees to retain, remove, or protect and how this affects your proposed layout.

We can also provide an Arboricultural Impact Assessment (AIA) and Arboricultural Method Statement (AMS) as required by your LPA.

What Happens After the Survey?

Once you have the BS5837 report, it should be submitted as part of your planning application. If approved, any retained trees must be protected as specified. If your plans change or construction phases are delayed, an updated tree survey may be needed.
