Tree Survey Cost When Selling Your Property

Trees are one of the most valued features of a residential property. Mature oaks, established hedgerows, and well-placed garden trees can add thousands of pounds to your asking price and make your home stand out in a crowded market. But trees can also become a source of concern during the selling process — particularly when they are close to the building, subject to legal protections, or linked to structural issues such as subsidence.

A tree survey provides an objective assessment of the trees on your property: their condition, their value, any risks they pose, and what management they need. This guide explains when a tree survey is needed, what it costs, the different types of survey available, and how trees can affect your sale in England and Wales.

What is a tree survey?

A tree survey is a professional inspection of the trees on or adjacent to a property, carried out by a qualified arboriculturist. The survey records the species, size, condition, and estimated remaining life of each tree, and assesses any risks the trees may pose to the property, its occupants, or neighbouring land.

There are several types of tree survey, each suited to different circumstances:

Visual tree assessment

A visual tree assessment (VTA) is the most basic form of tree survey. The arboriculturist inspects each tree from ground level, looking for signs of decay, structural weakness, disease, or damage. A VTA is typically sufficient when you need a general overview of tree health and any obvious risks. It does not involve invasive testing or detailed root mapping.

BS5837 tree survey

A survey carried out in accordance with British Standard 5837:2012 (Trees in relation to design, demolition and construction) is the most commonly requested type during property transactions and planning applications. It categorises each tree into one of four retention categories:

• Category A — Trees of high quality with an estimated remaining life of at least 40 years
• Category B — Trees of moderate quality with an estimated remaining life of at least 20 years
• Category C — Trees of low quality with an estimated remaining life of at least 10 years, or young trees with a stem diameter below 150mm
• Category U — Trees in such a condition that they cannot realistically be retained as living trees for longer than 10 years

The survey also maps root protection areas (RPAs) for each tree, which define the minimum area around a tree that must be protected from disturbance to safeguard its health and stability.

Arboricultural impact assessment

An arboricultural impact assessment (AIA) goes beyond the BS5837 survey by evaluating the likely effect of proposed development or construction on existing trees. If you are selling a property with planning permission for an extension, or if the buyer intends to develop the site, an AIA may be required by the local planning authority.

How much does a tree survey cost?

Tree survey costs vary depending on the type of survey, the number and size of trees, site access, and the arboriculturist's location. The table below sets out typical costs for residential properties in England and Wales as of 2026.

These figures are a guide only. Complex sites with numerous large trees, difficult access, or urgent timescales may cost more. Always obtain at least two quotes from qualified arboriculturists and confirm whether VAT is included in the quoted price. Tree survey costs form part of the broader costs of selling a house and should be factored into your budget early.

When do sellers need a tree survey?

There is no blanket legal obligation to obtain a tree survey before selling your home. However, there are several common situations where one is strongly advisable or effectively required:

Trees subject to a Tree Preservation Order

If any trees on your property are covered by a Tree Preservation Order (TPO), the buyer's solicitor will almost certainly raise enquiries about their condition and any recent or planned works. A tree survey provides an authoritative record of the protected trees' health, condition, and management requirements, which helps satisfy these enquiries and reassures the buyer that no enforcement issues exist.

You can check whether trees on your property are subject to a TPO by contacting your local planning authority or searching their online planning portal. Many councils maintain a public register of TPOs.

Trees within a conservation area

If your property is in a conservation area, all trees with a trunk diameter of 75mm or more (measured at 1.5 metres above ground level) are automatically protected. You must give the council six weeks' written notice before carrying out any work. A tree survey documents the current condition of all protected trees and can demonstrate that you have been managing them responsibly.

Large trees close to the building

Trees within influencing distance of the property's foundations — particularly on shrinkable clay soils — can trigger concerns about subsidence. The buyer's RICS surveyor may flag nearby trees as a risk factor and recommend further investigation. Having a tree survey ready demonstrates that you are aware of the trees and that they have been assessed by a qualified professional.

History of subsidence or structural movement

If your property has any history of subsidence, and tree roots were identified as a contributing factor, a current tree survey is essential. It shows the buyer that the trees responsible have been identified, managed, or removed, and that the risk of further movement has been addressed. This links directly to the information you must disclose on the TA6 Property Information Form.

Buyer or lender request

Sometimes the need for a tree survey only emerges during the conveyancing process. The buyer's surveyor may flag a concern in their Level 2 or Level 3 report, or the mortgage lender may make a tree survey a condition of their offer. Responding promptly with a professional survey prevents delays that could put the sale at risk.

Tree Preservation Orders explained

Tree Preservation Orders are one of the most important considerations when selling a property with significant trees. A TPO is made by the local planning authority under the Town and Country Planning Act 1990 (as amended) and the Town and Country Planning (Tree Preservation) (England) Regulations 2012.

A TPO can protect individual trees, groups of trees, areas of trees, or entire woodlands. Once a TPO is in place, it is a criminal offence to cut down, top, lop, uproot, wilfully damage, or wilfully destroy a protected tree without the council's written consent. Penalties can be severe: up to £20,000 in the magistrates' court, or an unlimited fine in the Crown Court for destroying a protected tree.

As a seller, you should be aware of the following practical points:

• TPOs remain attached to the land, not the owner. They transfer automatically when the property is sold and bind all future owners.
• You must disclose any TPOs you are aware of on the TA6 form. Section 3 asks about planning matters, and any tree orders are directly relevant.
• If you need to carry out works to a TPO tree (for example, pruning overhanging branches), you must apply to the local planning authority for consent before starting. This process typically takes up to eight weeks.
• A tree survey can support an application for works to a TPO tree by providing professional evidence that the proposed works are necessary for the tree's health or to address a legitimate safety or structural concern.

How trees affect property values

Trees can be a significant asset or a significant liability depending on their species, position, condition, and any legal protections. Understanding this balance is important when preparing your property for sale.

Research published by the Royal Institution of Chartered Surveyors (RICS) suggests that mature, well-maintained trees in a garden setting can add between 5% and 15% to a property's value. Trees provide privacy, reduce noise, improve air quality, and create visual appeal — all factors that buyers value.

However, trees can also reduce value or deter buyers when they:

• Are too close to the building, raising concerns about root damage, blocked drains, or subsidence
• Block natural light to habitable rooms, particularly in north-facing gardens
• Overhang neighbouring properties, creating a risk of disputes or liability for fallen branches
• Are subject to restrictive TPOs that limit what the buyer can do with their own garden
• Show visible signs of disease, decay, or structural instability
• Are very large species (such as oak, willow, or poplar) planted too close to foundations on clay soils

A tree survey gives you objective evidence of whether your trees are an asset or a concern, allowing you to address any issues before they become a negotiating point during the sale. This is one of the hidden costs of selling that many sellers overlook until a problem emerges during conveyancing.

Trees, subsidence, and insurance claims

Tree roots are one of the most common causes of domestic subsidence in England and Wales, particularly on clay soils. According to the Association of British Insurers, tree-related clay shrinkage accounts for a significant proportion of all domestic subsidence claims. When tree roots extract moisture from clay subsoil, the soil shrinks and can pull away from the building's foundations, leading to structural movement.

Species with the highest risk profile include willow, oak, poplar, elm, and ash — all of which have extensive root systems and high water demand. The National House Building Council (NHBC) publishes guidance on safe planting distances based on tree species and soil type. For example, an oak tree on highly shrinkable clay should be no closer than 20 metres to a building with shallow foundations.

If your property has a history of tree-related subsidence, a current tree survey is essential before selling. The survey should confirm:

• Whether the trees that caused the original problem have been removed or managed
• Whether any remaining trees are within influencing distance of the foundations
• What ongoing management is recommended to prevent recurrence
• Whether root barriers or other protective measures have been installed

This information links directly to what you must declare on your TA6 environmental section and helps reassure the buyer's insurer that the risk is being managed.

What to disclose on the TA6 form

The TA6 Property Information Form is the primary disclosure document sellers complete during conveyancing. Several sections are relevant to trees:

• Section 3 (Planning and building control) — Disclose any TPOs, conservation area status, and any applications for consent to carry out works to protected trees.
• Section 4 (Guarantees and warranties) — If tree works were carried out with a guarantee (for example, stump grinding or root barrier installation), provide details.
• Section 7 (Environmental matters) — Disclose any history of subsidence linked to tree roots, including details of insurance claims and remedial action.
• Section 9 (Neighbour issues) — If there have been disputes about overhanging trees, fallen branches, or boundary trees, these should be mentioned.

Honesty on the TA6 is not just a legal requirement under the Misrepresentation Act 1967 — it is also practical common sense. Buyers who discover undisclosed tree issues during their survey or searches will lose confidence in the transaction. Our guide on TA6 tree issues covers the disclosure requirements in full.

How to find a qualified arboriculturist

The quality of your tree survey depends on the qualifications and experience of the person carrying it out. To ensure the survey is credible and accepted by buyers, solicitors, and mortgage lenders, look for the following credentials:

• Arboricultural Association Registered Consultant — The gold standard for arboricultural consultancy in the UK. Registered consultants are assessed for technical competence, carry professional indemnity insurance, and adhere to the Association's code of ethics. Search the directory at trees.org.uk.
• Institute of Chartered Foresters (ICF) — Chartered members of the ICF hold professional qualifications in forestry or arboriculture and are bound by a code of professional conduct.
• Relevant qualifications — Look for a Level 6 Diploma in Arboriculture, a degree in arboriculture or forestry, or equivalent. Technician-level qualifications (Level 3 or 4) are suitable for straightforward visual assessments but may not be accepted for complex BS5837 surveys or subsidence investigations.
• Professional indemnity insurance — Essential. Without it, the surveyor's report has no backing if it is found to be negligent, and the buyer's solicitor may reject the survey.

Ask for a sample report before commissioning the work, and confirm that the arboriculturist is familiar with BS5837:2012 if a formal tree survey is required. A well-prepared report with clear tree maps, photographs, and retention recommendations will save time during conveyancing and give your buyer confidence.

What happens if the survey recommends tree removal?

If the arboriculturist recommends removing a tree, the process depends on whether the tree is legally protected.

Unprotected trees: You can instruct a qualified tree surgeon to remove the tree at any time. Costs for removal vary from around £200 for a small tree to £1,500 or more for a large tree in a confined space. Some sellers choose to remove problematic trees before listing to simplify the sale.

TPO-protected trees: You must apply to the local planning authority for consent before any work takes place. The council will consider the tree's amenity value and may grant consent (sometimes with conditions such as replacement planting), or refuse. If the tree is dead, dying, or dangerous, an exemption may apply, but you should still notify the council in writing and keep photographic evidence. A tree survey report supporting your application significantly strengthens your case.

Trees in a conservation area: You must give six weeks' written notice to the local planning authority. If the council does not respond within six weeks, the work may proceed. However, the council may use the notice period to make a TPO on the tree, which would then require a formal application.

Whether or not a tree is ultimately removed, the arboriculturist's report provides a documented basis for any decisions made. This is valuable evidence if questions arise during conveyancing about why a tree was removed or retained.

Practical steps for sellers

If your property has trees that could affect the sale, taking the following steps before listing will put you in the strongest position:

1. Check for TPOs and conservation area status. Contact your local planning authority or search their online register. Knowing the legal status of your trees before marketing avoids surprises later.
2. Commission a tree survey if appropriate. If trees are protected, close to the building, or linked to any past structural issues, a professional survey carried out by an Arboricultural Association registered consultant provides authoritative evidence for your buyer.
3. Address any recommended maintenance. If the survey recommends crown reduction, deadwood removal, or other management work, getting it done before listing shows proactive stewardship and removes a potential negotiation point.
4. Prepare your TA6 disclosures. Document any TPOs, conservation area protections, tree works carried out during your ownership, and any history of tree-related subsidence or insurance claims.
5. Keep records of all tree works. Invoices from tree surgeons, council consent letters, planning applications, and insurance correspondence all support your disclosures and help answer the buyer's solicitor's enquiries.
