Survey Types and Methodology
Our tree surveying and inspection services cover BS5837 surveys, arboricultural impact assessments, tree protection plans, method statements, development watching briefs, Visual Tree Assessments (VTA) and condition and health surveys. Where required, our impact assessments include appropriate methods of tree protection to ensure trees and their rooting environments are safeguarded from damage during and beyond development completion. We also assess fungal infection and internal trunk condition using PiCUS tomography, producing detailed reports for advanced risk evaluation.
All surveys follow the Visual Tree Assessment methodology, an internationally recognised approach to tree inspection and risk evaluation. Our surveyors detect underlying issues that may threaten a tree's health or structural soundness, including detailed assessments of condition, amenity value, signs of fungal disease, trunk integrity and pest infestations. Findings are captured using specialist GPS and CAD recording systems, enabling clients to maintain comprehensive tree records for forward planning and efficient data management.
Our arboricultural consultants work closely with developers, local authorities, landowners and project teams to deliver surveys that meet planning requirements and support informed decision-making. We also carry out aerial bat inspections under the supervision of a ground-based ecologist, assessing habitat features for evidence of use by bats. Where remediation is recommended, our own arboricultural teams can carry out the works on your behalf, providing a streamlined service from initial survey through to completion.

For clients requiring survey and assessment services, our dedicated arboricultural surveying team is based at our Penrith head office and travels nationally. Services include BS5837 surveys, impact assessments, arboricultural method statements, development watching briefs and Visual Tree Assessments. Where standard visual inspection is not sufficient, we offer advanced diagnostic assessments including Sonic Tomography, Biomechanical Assessment and IML Resi PD (Resistograph) testing, providing detailed internal data on trunk condition and structural integrity.
This combination of surveying, diagnostics and operational delivery within a single organisation allows us to manage projects from initial assessment through to completed works, reducing the coordination burden for our clients and ensuring consistency at every stage.
