Tree surveys are now a standard requirement for many planning applications across England – especially where development, access, or demolition takes place near existing trees. Costs can range from a few hundred pounds for a simple BS5837 survey to several thousand for complex or heavily constrained sites.
This guide explains what a tree survey actually includes, how much you should expect to pay in 2025, and when a planning consultant should be involved before you instruct any arboricultural work.
When You Need a Tree Survey for Planning
Local planning authorities typically request a BS5837:2012 Tree Survey where there are trees on or immediately adjacent to a development site. This is required to assess:
- tree condition, category and life expectancy
- constraints on layout and access
- root protection areas (RPAs)
- impacts of development on retained trees
If the site layout is not yet fixed, commissioning the wrong survey at the wrong time can lead to wasted costs. A quick planning appraisal can confirm whether a full BS5837 package is needed, or whether a simple constraints check is enough at the early stage.
The Main Types of Tree Survey (and Why Prices Differ)
1. BS5837 Tree Survey (Planning)
This is the most common survey for applications involving new development, intensification, extensions, or site access changes. A BS5837 package typically includes:
- tree survey and schedule
- Tree Constraints Plan (TCP)
- Arboricultural Impact Assessment (AIA)
- Arboricultural Method Statement / Tree Protection Plan (as required)
2. Mortgage or Insurance Tree Survey
Used for property purchases or insurance queries. These assess tree condition and any potential structural risk. They are normally quicker and cheaper than BS5837 reports.
3. Tree Condition / Risk Survey
Commissioned by landowners, estates and asset managers to understand safety, structural stability, or defects. These are not planning-related and pricing varies with the extent of the site.
Tree Survey Costs in 2025: Typical Price Ranges
The cost of a tree survey varies depending on the number of trees, site complexity and level of reporting required. Below is a realistic 2025 range based on typical UK arboricultural consultancy pricing.
BS5837 Tree Survey (Planning)
- Small sites (1–10 trees): £295–£450+VAT
- Medium sites (10–25 trees): £500–£900+VAT
- Larger sites or complex access: £900–£1,500+VAT
- Full BS5837 package (TCP, AIA, AMS): £750–£2,500+VAT depending on scope
Mortgage, Insurance & Condition Surveys
- Mortgage tree survey: £250–£450+VAT
- Tree condition/risk survey: £300–£750+VAT
- Large estates, schools or commercial sites: £750–£2,000+VAT
Specialist Add-Ons
- Decay detection / tomography: £400–£1,000 per tree
- Root investigation / air-spade excavation: £750–£1,500
- Tree climbing inspection: £300–£600
For most planning applications involving typical gardens or residential plots, survey costs sit at the lower end of the ranges above.
Why Tree Survey Quotes Vary So Much
Several factors impact the cost of a BS5837 survey:
- Number of trees — the biggest cost driver.
- Site constraints — limited access, steep ground, or large crown spreads require more work.
- Whether a layout exists — without one, you may need a staged survey to avoid redesign later.
- Level of reporting required — basic survey only vs full AIA and AMS.
- Location and travel — rural or remote sites cost more.
Two quotes for the same site can differ by several hundred pounds simply because one consultant has assumed a full AIA/AMS package, while another has priced a basic survey only.
How Long a Tree Survey Is Valid For
Tree survey data is normally considered valid for 12 months, although some local planning authorities may accept surveys up to 24 months old if tree conditions have not changed.
If your planning application is delayed or redesigned, the survey may need updating – which is another reason to scope it correctly from the start.
Why a Planning Consultant Should Be Involved Before You Instruct a Survey
Tree surveys are often instructed too early, or on the wrong scope, leading to unnecessary spend and redesign. A quick planning review can ensure:
- the survey type matches the development strategy
- the arboricultural work supports, rather than restricts, the proposed layout
- you avoid commissioning unnecessary AIA/AMS work
- the report addresses planning policy requirements for your local authority
Approved Planning works with landowners and developers across Essex and Suffolk to identify the minimum viable survey scope needed to progress a planning application while keeping costs under control.
