If you’re a homeowner, you may need a Tree Health Survey where a mature tree shows signs of decline, disease, instability or damage close to a house, driveway or boundary. Insurers, lenders and local authorities often request independent evidence before decisions are made.
If you’re a developer or landowner, Tree Health Surveys are commonly required where retained trees influence layout, access, safety or long-term site viability. Early clarity avoids unnecessary retention assumptions, late redesign or post-consent complications.
A Tree Health Survey provides a clear, professional view of tree condition, risk and realistic management options.
Across London, tree health issues most often occur where mature trees are embedded within dense urban environments. Typical contexts include:
Residential streets where trees overhang buildings, pavements and highways
Transport corridors and development sites with retained trees
Public open spaces and estate land with ageing tree stock
Locations affected by extreme weather events
Assessments prioritise public safety, liability and management planning.
We deliver Tree Health Surveys across Greater London, supporting developers, managing agents and landowners across residential, commercial and public sites.
Tree health can quickly become a material consideration where decline, disease or structural weakness creates risk to people, property or development proposals. Local authorities, insurers and landowners rely on clear arboricultural evidence to distinguish between trees that can be responsibly retained and those requiring intervention.
Under the Town and Country Planning Act 1990, trees may influence planning decisions where safety, amenity or future management is relevant. Where works are proposed, BS 3998 (Tree Work – Recommendations) provides the professional framework for appropriate arboricultural intervention, while BS 5837 may apply where tree condition affects layout, access or development feasibility.
Our Tree Health Surveys are commercially aware, proportionate and planning-led, designed to support real-world construction sequencing, access logistics and foundation strategy without unnecessary escalation.
Our Tree Health Survey typically provides:
Professional assessment of tree condition and structural integrity
Identification of disease, decline or defect risk
Practical management or remediation recommendations
Reporting aligned with London LPA, insurer and lender expectations
Our experts provide clear decision-ready arboricultural evidence across London.
Review of site details, concerns and any planning or insurance context.
Detailed inspection of tree condition, structure, vitality and defects.
Clear evaluation of safety, longevity and management implications.
Integration with other arboricultural or ecological surveys where required.
Need clarity on tree health in London?
We’ll assess any risk thoroughly and help you move forward with confidence.
A tree health survey is often required where trees may influence a planning application in London. Local Planning Authorities across London boroughs, such as Greater London Authority and individual councils, may request arboricultural information to assess tree condition, safety, and how trees affect development proposals.
London’s dense built environment means trees are often located in close proximity to buildings, basements, roads, and utilities. A tree health survey helps identify risks and constraints, ensuring trees can be safely retained or appropriately managed.
On constrained urban sites, a tree health survey assesses structural condition, signs of decay or damage, and overall vitality. It also considers how trees interact with foundations, underground services, access routes, and neighbouring properties.
Yes, tree health surveys are often required for basement excavations, extensions, and infill developments. These types of works can affect tree stability and root systems, making early assessment essential.
Urban conditions such as limited rooting space, pollution, soil compaction, and previous construction activity can affect tree health over time. These factors may lead to stress, decline, or structural weakness if not properly managed.
Common issues include structural defects, decay, historic pruning wounds, restricted root growth, and decline linked to urban stress. Trees in heavily built up areas may also be affected by ongoing development pressures.
Yes, trees located close to neighbouring buildings or boundaries are typically included in a survey. This ensures that potential risks, constraints, and responsibilities are properly understood, particularly in densely developed areas.
Many trees in London are protected by Tree Preservation Orders or are located within conservation areas. Permission is required before carrying out works, and a tree health survey provides the supporting information needed to justify any proposed management.
Yes, tree health surveys are commonly used to support the management of high value residential and commercial properties in London. They help identify maintenance needs, monitor tree condition, and manage risk over time.
A tree health survey should be arranged as early as possible where planning, development, or safety considerations apply. Early assessment helps identify constraints, inform design decisions, and reduce the risk of delays in complex planning environments.
