Arboricultural Consultancy in Swansea & the Gower

Swansea’s landscape is diverse — combining dense urban development, coastal exposure, parkland and rural surroundings extending into the Gower Peninsula. Mature trees play an important role in local character, biodiversity and amenity value.

Swansea Council frequently requires BS5837-compliant tree surveys where development proposals may affect existing trees. Conservation areas and Tree Preservation Orders are common across established residential districts.

Coastal exposure, strong prevailing winds and salt-laden air can also influence tree condition and long-term stability, making proactive assessment particularly important in certain areas.

We work with:
  • Homeowners concerned about tree condition or safety
  • Developers preparing planning submissions
  • Architects and planning consultants
  • Landowners and estate managers
  • Insurers and structural engineers

Our reports are clear, structured and tailored to site-specific conditions.

Tree Safety Inspections in Swansea
Trees located near highways, public open spaces, coastal paths and residential properties require periodic safety assessment.
Our Tree Safety Inspections evaluate:
  • Structural integrity and stability
  • Signs of decay or structural defects
  • Storm-related damage
  • Risk in relation to occupancy levels

Swansea’s coastal climate can increase wind loading and stress on trees, particularly during seasonal storms. Proactive monitoring helps manage risk responsibly while supporting long-term retention.

If you are submitting a planning application in Swansea and trees are present on or near the site, a BS5837:2012 tree survey may be required.
Our BS5837 services include:
  • Tree categorisation and condition assessment
  • Root Protection Area (RPA) calculations
  • Arboricultural Impact Assessments
  • Tree Protection Plans
  • Arboricultural method statements

Early arboricultural involvement ensures trees are properly integrated into site layout and construction planning, reducing the risk of delays or redesign.

Where a tree shows signs of decline, structural weakness or suspected decay, further investigation may be necessary.
An In-depth Tree Assessment may involve:
  • Detailed structural evaluation
  • Decay detection investigations
  • Assessment of high-value or veteran trees
  • Long-term management planning

This service is particularly valuable for prominent coastal trees or mature specimens within conservation areas.

Tree-related subsidence can occur where high water-demand species interact with shrinkable clay soils. While Swansea’s coastal geology varies, certain inland areas may contain clay subsoils susceptible to seasonal movement.
Our Tree Subsidence Surveys assess:
  • Tree species and water demand
  • Distance between trees and structures
  • Soil type and ground conditions
  • Foundation information (where available)
  • Evidence of structural movement

We provide clear, evidence-based conclusions to support homeowners, insurers and engineers.

FAQ – Tree Surveys in Swansea

Do I need a tree survey for planning permission in Swansea?
In many cases, yes. Swansea Council may require a BS5837 tree survey where trees are present on or adjacent to a proposed development site. The survey assesses tree quality, Root Protection Areas and potential construction impacts. Submitting a compliant arboricultural report ensures trees are properly considered within the design process and helps prevent delays during planning determination.
Trees located in coastal areas such as Mumbles and Swansea Bay can be exposed to strong winds, salt spray and variable soil conditions. Over time, these factors may influence structural integrity and long-term stability. Regular Tree Safety Inspections help identify early signs of stress or weakness, allowing proportionate management to be implemented before defects become significant.
Inspection frequency depends on location, condition and surrounding land use. Trees near highways, schools, public parks or high-footfall areas generally require more frequent monitoring than those in low-occupancy rural settings. Following severe storms, additional inspections may be advisable. A professional Tree Safety Inspection establishes an appropriate monitoring schedule based on site-specific risk.
A BS5837 survey includes tree categorisation, condition assessment and calculation of Root Protection Areas. It identifies how trees may constrain development and outlines protective measures during construction. This ensures trees are safeguarded while enabling sustainable site design. The survey often forms part of a broader Arboricultural Impact Assessment submitted with a planning application.
In certain circumstances, yes. Where shrinkable clay soils are present and high water-demand species are located close to buildings, seasonal soil movement can occur. However, not all cracking is tree-related. A Tree Subsidence Survey provides a detailed, evidence-based evaluation to determine whether trees are likely to be influencing structural movement in a specific case.
