Our Core Services Across All Locations

Tree Safety Inspections

We assess structural integrity and potential risk in trees located near highways, public spaces, residential properties and commercial premises. Our inspections are evidence-based and proportionate, balancing safety with long-term tree retention.

BS5837 Planning Surveys

Where development is proposed and trees are present, local authorities may require a survey in accordance with BS5837:2012. We provide:

Tree categorisation, Root Protection Area (RPA) calculations, Arboricultural Impact Assessments, Tree Protection Plans, Method statements

Our reports are structured to integrate seamlessly with architectural and planning submissions.

In-depth Tree Assessments

Where trees show signs of decline, structural weakness or suspected decay, we carry out detailed investigations to inform management decisions. This service is particularly valuable where high-value or veteran trees are involved.

Tree Subsidence Surveys

Where structural movement is suspected, we assess the relationship between trees, soil type and building foundations. Our subsidence reports provide clear, independent conclusions to assist property owners, engineers and insurers.
