Mortgage tree report

Mortgage lenders are primarily concerned with the long-term structural integrity of the property they are lending against. Trees close to a building introduce risk that a standard mortgage valuation does not assess in detail: root systems can cause subsidence in shrinkable clay soils, branches can cause direct physical damage, and the presence of a Tree Preservation Order can limit what future owners are permitted to do.

When a surveyor notes mature trees in close proximity to the property, the lender’s risk team will often ask for a specialist arboricultural report before releasing funds. Lenders including Barclays and HSBC routinely request this as part of their due diligence process. It is increasingly common and is not a reflection on the property itself — it is simply the lender satisfying themselves that the risk has been properly examined.

The same requirement can also come from your insurer. If your buildings insurance provider has flagged trees as a concern, a mortgage tree report addresses their needs in exactly the same way.

The report assesses every tree on or near the property that could affect the building, its foundations, drainage, or boundary structures. This includes trees on neighbouring land where their canopy or root system could reach the property — not just trees within the boundary.

The report is structured around five areas. Tree identification and data covers the species, dimensions, and location of every relevant tree, giving the lender a clear picture of what is present and where. The risk assessment determines the likelihood of tree failure, falling branches, or direct structural damage. The subsidence analysis examines soil conditions and the relationship between root systems and the building’s foundations. The legal and planning review confirms whether any trees are protected by a Tree Preservation Order or whether the property falls within a conservation area, and sets out what that means for future management. Finally, recommendations and management sets out any works required, with an estimated cost, so the findings are immediately actionable.

A mortgage valuation is carried out for the lender to confirm the property’s value. It is a brief assessment and does not include detailed analysis of tree-related structural risk. When the valuer notes trees as a potential concern, they flag it for specialist review — that is where we come in.

A tree survey for mortgage purposes is a standalone report prepared by a qualified arboricultural consultant with specific expertise in tree and building interactions. It goes into a level of detail the valuation cannot provide and gives the lender the specialist opinion they need to proceed with confidence.

We keep the process straightforward and move as quickly as the conveyancing timeline requires.

Step 1: Get in touch. Provide us with the property address, an indication of the trees present, and any correspondence from your lender or insurer setting out what they need. We will send you a fixed quote within a few hours.

Step 2: Confirm your booking. Once you are happy to proceed, we agree a date for the site visit. We work around your availability and aim to attend as quickly as possible.

Step 3: Site inspection. One of our arboricultural consultants visits the property and inspects all relevant trees, including any on neighbouring land within influencing distance of the building. The inspection covers tree health, structural condition, species identification, proximity to foundations and drainage, and soil type.

Step 4: Report production. The consultant prepares a detailed written report based on the site findings, structured to meet the requirements of mortgage lenders and insurers.

Step 5: Delivery. The completed report is sent to you, ready to submit to your lender or insurer. If they have follow-up questions or require any clarification, we are available to assist.

Not all trees near buildings present the same level of risk, and soil type is one of the most important factors. Trees growing in shrinkable clay soils can cause subsidence by extracting moisture and causing the ground to contract. The same tree on a sandy or gravelly soil presents far less structural risk.

The report will identify the soil type at your site and assess it alongside the species and size of the trees present. Some species, including willows, poplars, and oaks, are known to have more extensive root systems and are treated with greater scrutiny when they sit close to a building. The assessment considers the full picture rather than applying a blanket judgment based on proximity alone.

A report that identifies tree-related risk is not necessarily a reason to walk away from a purchase. In many cases the recommended action is straightforward: a crown reduction, removal of a specific tree, or installation of a root barrier. Where works are recommended, the report includes an estimated cost that can be used in negotiation with the seller or presented to the lender as part of a plan to address the risk.

Where findings are more serious, the report gives you the information you need to make an informed decision before you are committed. That is ultimately what the lender wants too: evidence that the risk has been properly understood.

If the property is one you later wish to develop, the arboricultural report can also feed into any future planning application, giving you a useful head start on the tree constraints picture.

Mortgage tree report pricing is based on the number of trees to be assessed and the size of the site. We provide a fixed quote upfront so there are no surprises.

To get started, provide us with the property address and any correspondence from your lender or insurer. We will confirm availability, turnaround time, and a fixed price promptly.
