What is a BS5837 Tree Survey?

A BS5837 survey is a specialist tree report required by local planning authorities when development is proposed near existing trees. It ensures that planning decisions account for:
  • Tree health and quality
  • Proximity to structures and boundaries
  • Root protection areas (RPAs)
  • Impacts of construction on retained trees
  • Opportunities for enhancement or planting
Our surveys are aligned with the British Standard BS5837:2012 – Trees in relation to design, demolition and construction.

    Arboricultural Method Statement (AMS)

    Step-by-step guide detailing how the development will take place without causing unnecessary negative impact to the trees.

We work closely with architects, developers and planning consultants to align our reporting with your build timelines and submission deadlines.

When Do You Need a Planning Survey?

You will likely need a BS5837 survey if your site includes or is close to:
  • Mature trees
  • Trees in a conservation area
  • Trees protected by Tree Preservation Orders (TPOs)
  • Boundaries adjoining parks, woodlands or roadsides
  • Any trees that may be affected by excavation, machinery or new structures
Local planning authorities will often refuse or delay applications without an appropriate arboricultural report. We ensure your application is supported by credible, professionally prepared documents.
