Good tree advice should be clear and usable. Our arboriculture consultant supports planners, developers, schools, housing providers and homeowners with straightforward reports, drawings where needed, and a plan that fits the site and budget.
Need a survey rather than advice? If the council or your architect has asked for a BS5837 tree survey for a planning application, that is a separate fixed-price service: see tree surveys, or BS5837 tree surveys in Preston if your site is in the city. This page covers wider consultancy: ongoing advice, disputes, inspections and expert support beyond a single report.

Consultancy service | When you need it | What you receive |
BS5837 tree survey for planning | Pre-app or validation on development sites | Schedule of trees, categories, constraints plan, recommendations |
Arboricultural Impact Assessment (AIA) | To assess effects of a proposed layout | AIA with RPAs, conflicts, mitigation |
Method Statement & Tree Protection Plan | Discharge of conditions and build phase | AMS, TPP, monitoring schedule |
Tree risk assessment | Duty of care for estates, schools, parks | Risk-rated survey and prioritised works list |
Mortgage or insurance report | Lender requests or subsidence concerns | Concise answers and next steps |
TPO and conservation area advice | Consent applications or emergency works | Checks, forms, supporting statements |
Management plans | Year-on-year maintenance and budgets | Cyclical programme with costs guidance |
Site supervision / clerk of works | Works near retained trees | Monitoring notes and sign-off reports |
For development sites we complete the full BS5837 process: data capture, quality categories, constraints, impact assessment and mitigation. You receive drawings for the Tree Constraints Plan and Tree Protection Plan, plus an arboricultural method statement that a contractor can follow. It keeps validation, discharge of conditions and site set-up straightforward.
Estates, schools and public spaces need a sensible inspection regime. We assess trees in context, explain risks in plain English and provide a prioritised works list. The aim is a safe, manageable site, not unnecessary cutting.
We check status, prepare applications and provide the statements local authorities expect. If a tree presents an immediate danger, we document the position and support the notifications that follow.
Lenders want direct answers. We inspect, address the specific questions raised, and give practical recommendations so the transaction can proceed.
For housing providers, business parks and utilities we create cyclical maintenance plans. You get predictable costs, fewer reactive call-outs and better presentation across sites.
Where retained trees sit close to works, we provide toolbox talks, pre-start briefings, protection checks and ongoing monitoring, with short notes and photos for your records.

Get in touch with Great Oaks today. We’re happy to answer any questions relating to arboriculture or grounds maintenance, or provide further info about our chainsaw courses.

Can you help at pre-application stage?
Yes. Early input often avoids clashes by aligning layout and root protection areas before designs are fixed.
Do you work across the North West?
We are based in Preston and cover Lancashire, Greater Manchester, Merseyside, Cumbria and nearby areas.
Can you supervise works near retained trees?
Yes. We provide monitoring visits with short notes and photo evidence to keep construction compliant.
How soon can we have a report?
Turnaround depends on size and season. Tell us your deadline and we will plan accordingly.
