Frequently Asked Questions (FAQ)

We specialise in two core areas: Tree Condition Surveys & tree reports for safety and management; and BS 5837 surveys for planning (TCR, TCP, AIA, TPP, AMS). We also handle TPO applications and mortgage/subsidence reports.

A Tree Condition Survey is the on-site assessment of health, structure, and risk. The tree report is the plain-English write-up you receive afterwards: findings, risk context, and prioritised recommendations (with general advice on future monitoring).

Usually, yes. Most councils require a BS 5837 survey where construction might affect trees. We produce a Tree Constraints Report (TCR) and Tree Constraints Plan (TCP) first to inform design, then the Arboricultural Impact Assessment (AIA), Tree Protection Plan (TPP), and Arboricultural Method Statement (AMS) to support the application and delivery on site.

There isn’t a one-size-fits-all interval. Sensible inspection frequency depends on species, age, condition, site use/targets, and changes on or around the tree (e.g., construction, storms). We don’t prescribe fixed re-inspection periods; instead, your tree report includes general guidance on when to review again and what might trigger an earlier check (e.g., major weather events or noticeable changes).

Serious defects can be hidden (internal decay, root issues, cracks). A professional survey identifies risks early and provides proportionate recommendations—often pruning, bracing, or monitoring rather than felling.

Consent is required before undertaking works. We prepare and submit robust applications with supporting tree reports, ensuring proposals are justified and policy-compliant for the best chance of approval.

BS 5837:2012 sets out how to manage trees in relation to design, demolition and construction. Trees should be considered at concept stage so layouts can respond to categories, Root Protection Areas (RPAs), and constraints—saving time and redesign costs later.

BS 5837 uses category grading (A: high quality, B: moderate, C: low, U: remove/unsuitable for retention) to guide design. The RPA is the minimum area around a tree that must be protected to safeguard rooting (shown on the TCP and used to set protective fencing in the TPP).

Yes. We can overlay surveyed trees on your plans and provide outputs compatible with common formats (e.g., DWG/DXF/PDF). Where helpful, we can also provide tabulated schedules for import into your project workflows.

Your site address/postcode, the survey/report type (e.g., Tree Condition Survey or BS 5837), any deadlines, and (for BS 5837) the current drawings and planning stage. Let us know about TPO/Conservation Area status if known.

Lenders/insurers often request a focused tree report to assess potential risk to structures, particularly on clay soils. We provide fast, impartial assessments to keep transactions moving.

For mortgage/subsidence, planning (BS 5837), TPO/Conservation Area applications, and many insurance or council cases, providers expect an independent, qualified arboricultural consultant. We diagnose and report; any tree surgery is then carried out by your chosen contractor.

Tree Condition Surveys: a clear PDF tree report with observations, photos where helpful, risk context, and prioritised recommendations (plus general guidance on future review).

BS 5837 reports: a Tree Constraints Report (TCR), Tree Constraints Plan (TCP) with categories/RPAs, and (as required) the Arboricultural Impact Assessment (AIA), Tree Protection Plan (TPP), and Arboricultural Method Statement (AMS) to support planning and on-site protection.

Availability is typically within a few working days. Pricing depends on tree numbers, site complexity, and report type; small domestic surveys usually start from £300. See our Prices for guidance.
