Safety and Compliance
Our utility arboriculture services include targeted pruning and crown reductions to reduce outage risk, vegetation clearance for access and maintenance programmes, cyclical contracts, one-off projects and rapid-response emergency callouts. Whether managing planned programmes or responding to urgent situations, we have the experience and capability to meet the needs of utility providers.
All works are subject to detailed hazard inspections, risk assessments and pre-start planning, with most contracts delivered via a strictly controlled permit system. We coordinate closely with network operators, contractors and landowners to meet statutory obligations and asset protection standards.
Our operatives are trained to industry safety and competence schemes, using insulated tools, trained climbers, tracked access platforms and GIS-enabled reporting to manage complex, constrained sites efficiently. Environmental and archaeological considerations are integrated into every job, with protected species checks, seasonal timing protocols and habitat-sensitive techniques employed to minimise ecological impact. We offer flexible contracts, transparent documentation and audit-ready records to support a professional, compliant service.

Specialist Arboricultural Fleet
Comprehensive Tree Management, from Survey to Solution
Our arboricultural capability covers the full scope of tree management. Routine tree surgery, stump removal and vegetation clearance are delivered by NPTC-certified surgeons from all five regional offices, supported by a specialist fleet of modern plant and equipment.
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.
