Ensure that any trees on your London site don’t create potential health and safety issues by organising VALID tree risk management through Arbtech.
Safeguarding the capital’s sprawling urban forest is a task that requires a technical and evidence-led strategy. In a city where the iconic London Plane is a staple and residential density is incredibly high, failing to manage unstable timber can lead to a breach of statutory health and safety duties or the rejection of planning applications.
We provide a type of tree risk assessment in London that targets high-risk specimens while facilitating legal compliance. Our team of tree consultants and tree surveyors often began their careers in arboricultural services as qualified arborists and tree surgeons. The hands-on history is vital for identifying potential hazards posed by present trees and diagnosing structural defects, though we now focus purely on expert advice and professional reports rather than physical surgery.
The risk to the public grows whenever a tree condition begins to decline, especially in a city with such high footfall. Beyond the obvious danger of diseased trees, the structural integrity of a specimen can be undermined by root encroachment or soil compaction, preventing damage to the capital’s pavements and disrupting underground utilities.
Construction projects can exacerbate the potential issues, as excavating near a root plate often leads to structural weakness and an elevated chance of failure. Navigating regular tree safety expectations and the legal duty associated with conservation areas or tree preservation orders (TPOs) is a challenge for any property manager. Our VALID tree risk survey is designed to map out every risk posed to ensure that you stay compliant.
Often referred to as a tree risk assessment survey or a tree health assessment, a comprehensive tree audit is a versatile tool for various London stakeholders. Landowners frequently commission these as part of their duty of care to mitigate potential risks and ensure safety.
Additionally, a local council or a mortgage provider might request professional tree surveys during a conveyance to help them reach informed decisions. Furthermore, assessing tree health is vital for managing the hazards of trees in bustling public spaces, particularly following extreme weather events.
Our thorough inspections cover every corner of the 33 London local authorities, from private gardens to vast commercial estates. Through early detection, we pinpoint hidden issues in a large tree that might be invisible to the untrained eye.
Our tree services are tailored to help you meet local authority requirements while satisfying your legal responsibilities through professional recommendations that are both reasonable and proportionate to the site’s needs.
Our approach to tree management typically begins with a visual tree assessment (VTA), followed by a detailed tree risk analysis where necessary. The ground-level tree inspection cycles focus on identifying red-flag features such as fungal fruiting bodies, cracks or significant decay.
The resulting risk ratings are calculated by weighing the likelihood of a tree failing against the occupancy levels of the surrounding environment and the severity of the potential impact.
The VALID software produces a traffic-light status to confirm the level of risk. In more complex cases, we may employ specialist tools like sonic tomography or aerial climbs to investigate internal cavities. A final tree report is then compiled to provide expert advice, document the site data, and justify the risk scores.
VALID tree documentation is essential for protecting people, meeting the specific needs of your project, and ensuring the long-term health of your tree stock.
By partnering with our consultancy, you can ensure public safety and invest in the long-term condition of valuable trees and protected trees on or near your site.
Our VALID-accredited experts offer the professional advice required to manage your stock effectively, providing you with the peace of mind that your legal and safety obligations are being handled by specialists. We ensure that your trees remain a beautiful asset to the city without becoming an unmanaged liability.
