Our Service...

No matter the size of your project, our range of development reports and plans are designed to get your project through planning first time around. These are available at a competitive rate, and in a timeframe to suit you.

We communicate with your team from the earliest stage of the design process. In doing so, we are able to ensure that your planning application goes smoothly and efficiently.

If you have already submitted a planning application and have had it refused or returned with tree related conditions, we are able to propose arboricultural and engineering solutions to satisfy the planning officers and get you that all important 'application approved' letter through the door.

The Process

What You'll Need, and When...

Feasibility / Conceptual Design

Our BS5837 Tree Survey will map all trees on your site, and also those on neighbouring land that may be affected by the development. 

We record data such as the tree’s species, canopy dimensions such as height and spread, life stage, and categorize it either a Cat. A, B, C or U tree, depending on its arboricultural and amenity value. 

Following the completion of the Tree Survey, we can produce a Tree Constraints Plan. This provides the project's design team with an objective assessment of the surrounding trees; highlighting any constraints to development that they may present.

Using this, the design team will be able to identify a ‘developable area’, free from non-rectifiable tree constraints.

Once a conceptual design has been selected, we will produce an Arboricultural Impact Assessment identifying the potential impact which the development may have on the tree population.

This document will also specify specialist construction methods to reduce  any arboricultural impact, where appropriate.

Upon finalisation of a design, we will produce an Arboricultural Method Statement and its accompanying Tree Protection Plan.

These documents provide a detailed methodology for the implementation of the mitigation measures, previously outlined in the Arboricultural Impact Assessment. This will instruct site contractors on how to fulfill their role in an arboriculturally sensitive manner.


Planning Submission /

Technical Design



Once your project's planning has been granted, in some cases it will be necessary for an arboriculturalist to be present during operations which may result in damage to retained trees. This generally involves one of our consultants briefing and advising the site workers on how their role may damage the tree, and what can be done to reduce the risk of damage.

Very professional service, delivered quickly and to a high standard. I needed a simple Arboricultural Method Statement to protect a single tree during construction works, and the information provided was perfect for the task. Ben was very helpful when discussing the project, before and after his appointment. I will be using Ligna again in the future.
