If you’re planning a development project in the UK, especially in regions like Hertfordshire or Devon, understanding the BS5837 tree survey is essential. This survey, guided by the British Standard BS5837:2012, ensures that trees are appropriately considered during all phases of development—from design to demolition and construction. Here are five important things to know about this essential survey.
1. What Is a BS5837 Tree Survey?
A BS5837 tree survey is a detailed assessment carried out by a qualified arboriculturist to evaluate all trees on or near a development site. The survey identifies each tree species, its physical characteristics, structural condition, and overall health. The purpose of this survey is to help planners, architects, and developers make informed decisions regarding tree retention, protection, or removal.
BS5837 surveys are not only useful for assessing individual trees but also vital for creating a long-term management plan that ensures safety, sustainability, and compliance with planning regulations.
2. Why Is It Important for Planning Applications?
Most local planning authorities require a BS5837 tree survey as part of the application process for any development that involves or is close to existing trees. This ensures that any construction work respects environmental standards and minimises harm to valuable trees and their root systems.
Without a proper tree survey, planning applications may be delayed, rejected, or subject to costly revisions. Providing a BS5837 report demonstrates that you’ve considered the impact of your project on existing trees and are committed to following best practices in development and sustainability.
3. What Does the Survey Include?
A complete BS5837 tree survey consists of several critical components that offer a comprehensive overview of the tree population on a site:
Tree Schedule: This includes details about each tree’s species, height, diameter, crown spread, life expectancy, and current condition.
Tree Constraints Plan (TCP): A scaled map showing tree locations, canopy spreads, and root protection areas. This is crucial for identifying no-build zones and construction buffers.
Arboricultural Impact Assessment (AIA): Evaluates how the proposed development will affect the existing trees and provides mitigation strategies for any identified risks.
Arboricultural Method Statement (AMS): A practical guide outlining how construction work will be carried out while protecting the retained trees. This might include ground protection techniques, fencing guidelines, and permitted working distances.
4. Understanding Tree Categories
As part of the BS5837 survey, trees are categorised based on their quality and potential value in a development context. These categories help developers prioritise which trees to preserve or remove:
- Category A: High-quality trees with significant landscape value and long life expectancy.
- Category B: Trees of moderate quality that still offer useful amenity value.
- Category C: Low-quality or younger trees that are less significant in terms of landscape contribution.
- Category U: Trees that are dead, dying, or dangerous and should be removed for safety reasons.
Understanding these classifications helps streamline planning decisions and supports tree protection strategies that align with environmental policies.
5. When Should You Commission a BS5837 Tree Survey?
Timing is critical. It’s best to commission a BS5837 survey early in the design or planning stage of your project. This proactive step helps identify constraints and opportunities from the start, giving you time to adapt your plans to accommodate valuable or protected trees.
Early surveys also reduce the risk of unexpected costs or delays due to overlooked tree-related planning requirements. This is especially important in areas like Hertfordshire and Devon, where many trees are protected by Tree Preservation Orders (TPOs) or are located in conservation areas.
Why Professional BS5837 Tree Surveys Matter
A BS5837 tree survey is more than just a checkbox for planning permission—it’s a strategic tool that guides sustainable development. By understanding the condition, location, and value of existing trees, developers can design with nature in mind, reduce legal complications, and create healthier environments.

FAQ About BS5837 Tree Surveys
How long is a BS5837 tree survey valid for?
A BS5837 tree survey is typically valid for up to 12 months, assuming there are no major changes to the site or the trees during that time. However, if any construction work begins, trees are removed, or environmental conditions change, a follow-up assessment may be required. It’s always best to check with your local planning authority to ensure the survey remains current and acceptable.
Do I need a BS5837 tree survey even if there are no trees on my development site?
Yes, you may still need a BS5837 survey even if there are no trees directly on your site. Trees on adjacent land or close to site boundaries can still influence development and may have protected root zones that extend into your site. Local planning authorities often require confirmation that no off-site trees will be impacted by your proposal.
What happens if my development plans conflict with protected trees identified in the survey?
If protected or high-value trees conflict with your initial design, you may need to revise your plans to retain and protect them, especially if they are covered by a Tree Preservation Order (TPO) or are in a conservation area. Your arboriculturist can work with your architect to suggest design changes, mitigation strategies, or, if unavoidable, guide you through the process of applying for permission to remove or alter protected trees.
Is a BS5837 tree survey different from a general tree inspection or condition report?
Yes, they are different in scope and purpose. A general tree inspection or condition report focuses on the health and safety of individual trees, often for private property owners. In contrast, a BS5837 tree survey is specifically designed for planning applications and assesses how trees might be affected by, or affect, proposed development work. It includes mapping, impact assessments, and construction guidance that a simple tree condition report would not provide.
