At Gradwell Group, we understand the importance of protecting trees during the planning and development process. An Arboricultural Impact Assessment (AIA) is a key part of meeting planning requirements, identifying how proposed works may affect existing trees, and setting out practical measures for their protection.
Our experienced consultants provide clear, comprehensive reports in line with BS5837:2012 (Trees in Relation to Design, Demolition and Construction – Recommendations).
We assess the condition, value, and constraints of trees on-site, evaluate potential impacts, and recommend mitigation strategies to ensure a balance between development needs and environmental responsibility.
Whether you are a homeowner submitting a planning application or a developer managing a large-scale project, our team can guide you through the arboricultural planning process to achieve compliance and sustainable outcomes.
Gradwell Group has a highly experienced team of arboricultural consultants, operating nationwide across the UK. All our specialists are fully qualified, accredited, and insured. Our field teams are supported by a dedicated in-house technical department, enabling us to deliver Arboricultural Impact Assessments swiftly and with precision.
We work to the highest industry standards to ensure your project meets both planning requirements and tree protection obligations.

An Arboricultural Impact Assessment (AIA) is a formal report that evaluates how trees may be affected by a proposed development, whether through construction, demolition, or changes to land use. It forms part of the planning process and is typically required by local planning authorities before granting permission. An AIA helps ensure trees are properly considered at the design stage, minimising conflicts later in the project.
Planning authorities place high value on trees due to their ecological, visual, and community benefits. Where trees are present on or near a development site, an AIA is often mandatory to demonstrate how impacts will be managed. This includes trees protected by Tree Preservation Orders (TPOs) or those located within conservation areas. A thorough AIA not only satisfies planning requirements but also reduces delays, objections, and costly redesigns.

Our consultants are members of relevant professional bodies, fully insured, and trained to the latest standards. We pride ourselves on delivering accurate, practical advice that balances development objectives with environmental responsibility.
All our assessments are produced in line with BS5837:2012 – Trees in Relation to Design, Demolition and Construction. This recognised industry standard sets out how trees should be managed throughout the development process. By adhering to these guidelines, we ensure your project aligns with best practice, protecting valuable tree assets while avoiding unnecessary risks and liabilities.
Our AIA process is structured and comprehensive. It begins with a detailed site survey to record tree species, size, condition, life expectancy, and root protection areas.
We then analyse how proposed works could impact these trees—whether through direct loss, disturbance of roots, or changes to soil and drainage. Finally, we provide a clear, illustrated report with recommendations, including mitigation strategies such as protective fencing, root zone management, or selective tree removal where justified.
Our reports are written to a high professional standard, ensuring they meet planning authority expectations. We work closely with architects, planning consultants, and developers to integrate tree-related considerations into the design process early on. By doing so, we help streamline planning applications, reduce the risk of refusal, and demonstrate a clear commitment to environmental responsibility.
