A basic BS5837 tree survey costs around £295–£760 in 2026 for a small site with a few trees, while a full BS5837 planning package — survey plus tree constraints plan, impact assessment, protection plan and preliminary method statement — typically costs £400–£1,500 or more, and several thousand pounds on large or complex sites. What you actually pay is driven by tree count, site complexity, and exactly which documents your local planning authority demands.
This page focuses on the price of a BS5837 survey specifically — what each part of the package adds, why quotes vary so widely, and how to avoid paying for the wrong scope. For the broader comparison across all survey types, see our tree survey cost guide and the annual 2026 price table.
What "BS5837 survey" actually means for pricing
BS5837:2012 is the British Standard for trees in relation to design, demolition and construction. It is guidance, not law — the word "Recommendations" is in its title and it uses "should", not "must". It becomes effectively compulsory only when a local planning authority requires it on its validation list, or imposes it through a planning condition. That is the first thing to understand about the price: you are not buying a legal certificate, you are buying a document set rigorous enough that a tree officer will accept it.
Colloquially a "BS5837 survey" means the whole document package, but each element is a distinct, separately priced deliverable:
| BS5837 deliverable | What it is | Roughly when it's needed |
|---|---|---|
| Tree survey + schedule | Record of every relevant tree: species, height, stem diameter, crown spread (four directions), age class, condition, U/A/B/C category and calculated RPA | Before design / pre-submission |
| Tree constraints plan (TCP) | Scaled drawing of tree positions, crown spread and RPA circles/polygons | Before design / pre-submission |
| Arboricultural impact assessment (AIA) | Assesses the proposed layout against the trees — what's removed, what's retained, what conflicts arise | Submitted with the application |
| Tree protection plan (TPP) | Barrier fencing, construction exclusion zones, ground protection, service routes | With application and/or at discharge |
| Arboricultural method statement (AMS) | The detailed "how" for works near roots — no-dig construction, foundation design, supervision | Often a pre-commencement condition |
The more of this stack you need, the higher the fee. A survey plus TCP for a couple of garden trees sits at the bottom of the range; a full package driving a multi-tree development from concept through to discharge of conditions sits at the top.
BS5837 survey prices in 2026
| Scope | Typical 2026 price |
|---|---|
| Basic BS5837 survey (small domestic, few trees) | £295–£760 |
| Full BS5837 planning package (survey + TCP + AIA + TPP + preliminary AMS) | £400–£1,500+ |
| BS5837 survey + AIA (typical development) | £500–£1,000 |
| Standalone AIA add-on | from ~£200 |
| Detailed method statement (post-permission) | additional fee |
| Large / complex / phased sites, many trees | £1,500 to several thousand pounds |
These are indicative UK market ranges for 2024–2025 rolled forward to 2026; every consultant prices to the individual site, so treat them as a budgeting guide, not a fixed tariff.
What drives a BS5837 fee
- Tree count. Each tree is individually measured and categorised, and its root protection area calculated at 12 × stem diameter (measured at 1.5m, capped at 707 m² / a 15m radius). Two garden trees is an hour on site; a wooded plot is dozens of individual records.
- Document scope. Survey-only is the floor. Adding the AIA, TPP and AMS multiplies the drawing and write-up time.
- Site complexity. Sloping ground, dense canopy, level changes, off-site neighbouring trees whose RPAs cross the boundary, and phased construction all add hours.
- Protected trees. TPO or conservation-area trees, and veteran/ancient trees — which carry an enhanced RPA of 15 × stem diameter and are treated as irreplaceable habitat — raise the level of assessment.
- Location and travel. Distance and regional rates both count; London and the South East tend to price higher.
- Accreditation. A report from an Arboricultural Association Registered Consultant (AARC) or ICF Chartered Arboriculturist costs more but carries the most weight with the tree officer and is least likely to be challenged. There is no legal licence to be an arboriculturist, so the accreditation is what distinguishes a report the council trusts from one it questions.
A worked example: rear extension near a neighbour's oak
Take a common domestic scenario. You want a single-storey rear extension, and there is a mature oak in the neighbour's garden with a stem diameter of about 600mm. Its RPA is 12 × 0.6 = a 7.2m radius circle (roughly 163 m²) — and a chunk of that circle projects across the boundary into where your foundations would go. Even though the tree isn't yours and isn't on your land, its RPA is a material constraint, so the council's validation list will almost certainly require arboricultural information.
Here the cost is not just a basic survey. You'd typically pay for the survey and TCP to plot the oak and its RPA, then an AIA showing the extension can be built without harmful incursion — probably with a no-dig or engineered foundation solution described in an AMS if any hard surface or footing sits inside the RPA. That pushes a nominal £300 "survey" into the £500–£1,000 bracket once the impact assessment and method thinking are included. Skipping it and hoping the council doesn't notice is the classic route to an invalidated application.
Why paying too little backfires
The single commonest reason applications stall over trees is a missing or inadequate BS5837 document at validation — the authority simply won't register the application. A cut-price report that omits RPA calculations, uses optimistic categories a tree officer rejects, or ignores neighbouring trees gets bounced, forcing a resubmission that costs far more in delay than the fee saved.
Watch for these failure modes in a cheap quote:
- No RPA figures — the technical heart of the assessment is missing.
- Survey done after the design is fixed — BS5837 expects the survey to inform the layout, not rubber-stamp it; a scheme that drives foundations or drainage through an RPA gets caught at AIA stage and forces redesign.
- Optimistic categorisation — grading a defective tree as B or A to make retention look easy; the tree officer regrades it and your layout no longer works.
- "Category R" on the schedule — a legacy 2005-edition code. In BS5837:2012 the removal grade is U (unsuitable for retention). Seeing "R" is a red flag that the consultant is working from outdated guidance.
- Off-site trees ignored — neighbouring RPAs crossing the boundary left unassessed.
A report that passes validation first time is the real economy. See how to find a tree surveyor for what to check before instructing.
Budget for the whole journey, not just the survey
Two costs catch people out. First, the AIA is usually needed once your layout exists and is priced separately from the survey. Second, permission is frequently granted with a pre-commencement condition requiring a detailed AMS and final TPP — and you cannot lawfully start work, even with full permission, until that condition is formally discharged in writing by the LPA. Preparing the detailed method statement, applying to discharge the condition (a fee is payable), and any conditioned site supervision during construction are all further costs. Factor the whole stack in from the outset.
Costs are set locally — check your council
There is no single national price or national rule, because the requirement itself is set locally. Each local planning authority publishes its own validation list, and those lists differ in what arboricultural information they demand and when — some want a full AIA, TPP and preliminary AMS up front, others accept a survey at validation and condition the rest. Tree-officer strictness, local TPO density, conservation-area coverage and the presence of ancient woodland or veteran trees all vary by area, and every one of those factors moves the fee.
So the honest answer to "what will it cost me?" always ends with: check your own authority's validation requirements first. PlanWatch tracks live tree-related planning activity per council, so you can see how trees are being handled where you're building — compare, for example, Leeds, Manchester, Bristol or Lambeth, and check your own area from the tree surveys hub. (BS5837 applies UK-wide as a British Standard, but the statutory framework is England-centric here; Scotland, Wales and Northern Ireland run parallel but distinct regimes.)
Bottom line
Expect £295–£760 for a basic BS5837 survey and £400–£1,500+ for a full planning package, with larger and protected-tree sites costing more — plus a separate fee for the post-permission method statement and any discharge/supervision work. Scope and tree count, not headline price, decide what you actually pay, and the cheapest quote is often the most expensive route once an invalidation adds months to your timeline.
