Tree Survey Services We Offer

 

Individual Tree Condition Assessments

Assess the health and stability of your trees to identify potential risks and recommend appropriate management strategies as well as producing an associated report. These are particularly useful for planning applications related to trees with Tree Preservation Orders (TPO) and trees within a conservation area.

 

Risk Assessment Surveys and Recommendations

Evaluate the likelihood of tree failure and its potential impact on people or property. Our detailed surveys include tailored recommendations to mitigate risks and ensure tree safety and sustainability. A site map is also produced showing the relative position of trees on your land. Risk surveys are an essential step in obtaining the relevant insurance, especially for commercial units, where compliance with safety standards is critical.

 

BS5837 Construction Surveys

Detailed surveys and reports to guide tree protection and management during construction projects, ensuring compliance with BS5837 standards.

 

Mortgage Report/Pre-Purchase Surveys

Specialist surveys to identify tree-related risks that could impact mortgage approvals or property value. These include evaluating subsidence risk to ensure the security and stability of your investment.

Quantified Tree Risk Assessment

 

We offer single, detailed tree surveys using the QTRA (Quantified Tree Risk Assessment) method, as well as large-scale site surveys for landowners managing multiple trees.

For sites with multiple trees, our surveys include a detailed site map that shows the location of trees across the site. A qualified member of our team will carry out a visual assessment from ground level to evaluate each tree’s overall health and safety condition, using the QTRA method to assess and inform you of the calculated risk.

Following the survey, we will provide a list of recommended works, along with a schedule detailing recorded risk.

As a landowner, conducting regular tree surveys is an important part of your duty of care. In the event of a claim related to a tree incident, an insurance company will typically require a recent survey to be provided.

When reporting, we use a negative style reporting approach. This means that all trees on the site that pose a potential risk for injury will be surveyed, but only those exhibiting defects that require remedial work will be recorded in the final report and plotted onto the map. Trees will be grouped appropriately and assigned a risk rating. Individual trees will be recorded if the QTRA calculator proposes a level of risk where remedial actions are considered appropriate. Trees that require work will be tagged or spray marked for felling.

A major benefit of the QTRA approach for surveys across expansive areas is its cost-effectiveness, particularly when compared to more traditional methods such as full inventory or full recording surveys. Unlike these methods, which can be time-consuming and resource-intensive, QTRA focuses on assessing large tree populations at high volume and relevance.

With QTRA, you receive only the information necessary to manage and reduce risks to ALARP (As Low As Reasonably Practicable), ensuring your duty of care is discharged in exactly the same way but at a fraction of the cost. This targeted approach avoids unnecessary data gathering, which is often irrelevant to the actual level of risk trees pose to public safety. Full recording or inventory methods can waste valuable resources by documenting details that do not contribute to managing risk.

In contrast, the QTRA approach strikes the right balance by providing the required level of detail while maintaining cost-efficiency and relevance, making it a much more practical solution for large-scale tree management.

We’ve received excellent feedback from clients using the QTRA approach, and our consultants follow a trusted, objective system that removes the noise from decision-making and supports real-world, risk-based land management.

Expert Tree Assessment Services

Under the Occupiers Liability Acts of 1957 and 1984, tree owners are obligated to maintain their trees in a safe condition to prevent any potential hazards. Our comprehensive tree survey and inspection services help you fulfil these duties effectively, ensuring both safety and compliance with the law.

Our tree assessment services are designed to cater to various client needs, from routine checks to detailed analyses. We conduct veteran tree surveys, manage internal decay detection, perform aerial tree inspections, and oversee tree work contracting. By adapting our services to meet the specific requirements of each client, we ensure that every aspect of tree safety and health is thoroughly evaluated. Our approach follows the best practices established by the National Tree Safety Group (NTSG) and Lantra, guaranteeing that our assessments are both accurate and reliable.

Advanced Technology and Detailed Reporting

We utilise the latest in computerised tree management software, including GPS (Global Positioning Systems) and GIS (Geographic Information Systems), to accurately plot and systematically record every detail of your trees. This technology aids in providing a clear and comprehensive overview of tree conditions and locations, enhancing the precision of our surveys. Each survey culminates in a detailed tree schedule, site plan, and a tailored report—available in electronic formats to minimise costs and environmental impact. This detailed documentation helps tree owners make informed decisions regarding tree management and maintenance strategies.

Certified Professionals and Customised Consultancy

All of our consultants and associates are certified with the Lantra Awards Certificate for Professional Tree Inspections, ensuring that your tree assessments are conducted by arboriculturally qualified and competent professionals. We go beyond simple inspections to provide you with effective natural-infrastructure solutions that balance commercial, environmental, and human needs, thereby naturally increasing the value of your land or property.

What our customers say

Frequently Asked Questions

What specific criteria do you use to determine the safety and health of a tree during an inspection?

During tree inspections, several criteria are assessed to determine the safety and health of a tree. These include the structural integrity of the tree, signs of decay or disease, root health, and the tree’s overall vigor. Inspectors also look for vulnerabilities such as cracks, weak branch attachments, and any previous storm damage. Environmental factors affecting the tree, such as its proximity to buildings or utility lines, are also considered.

How often should tree surveys and inspections be conducted to ensure ongoing safety and compliance?

The frequency of tree surveys and inspections should be based on the tree’s location, species, age, and health, as well as any previous maintenance records. Generally, it is recommended that trees in urban or public access areas be inspected at least once every three years. However, trees in more critical locations, such as near schools, playgrounds, or hospitals, should be inspected more frequently, ideally annually.

Can you provide examples of common issues identified during tree inspections and the typical recommendations for addressing these issues?

Common issues identified during tree inspections include fungal infections, structural weaknesses (such as cavities or significant splits), and pest infestations. Typical recommendations might involve pruning to remove dead or weak limbs, applying fungicide or pesticide treatments, or installing support systems like cables or braces to stabilise the tree. In cases where the tree poses a high risk, removal may be advised.

What happens if a problem is identified with a tree during a survey? What are the immediate steps taken to mitigate risk?

If a problem is identified during a tree survey, immediate steps to mitigate risk depend on the severity of the issue. For urgent hazards, such as a cracked limb over a roadway, immediate action may involve cordoning off the area and scheduling an emergency pruning or removal. For less critical issues, a plan is developed to address the problem within a specific timeframe, such as scheduling treatment or corrective pruning.

Are there any legal repercussions for tree owners who fail to conduct regular inspections or follow through with necessary maintenance identified in these inspections?

Yes, there are legal repercussions for tree owners who fail to conduct regular inspections or follow through with necessary maintenance. Under the Occupiers Liability Acts, tree owners have a duty to ensure their trees do not pose a risk to the public. Failure to uphold this duty can result in liability for damages caused by a tree, such as injury to persons or damage to property, and may lead to legal action being taken against the tree owner.

Do you work in both Hertfordshire and Devon?

Yes! We’ve been based in Hertfordshire for over 10 years and have recently opened a new branch in Devon headed up by our founder Ben!

Who typically requires a professional tree inspection?

We carry out inspections for private homeowners, schools, housing associations, local authorities, estate managers, commercial landowners, and anyone responsible for tree safety. If you own land with mature trees, a professional inspection can help reduce risk and demonstrate due diligence.

What’s the difference between a tree inspection and a full tree survey?

A tree inspection is a focused assessment of one or more trees to identify safety concerns or health issues. A full tree survey is more detailed and may include tagging, mapping, risk categorisation, and management recommendations — often required for planning or legal compliance.

Can you help with insurance claims or damage assessments related to trees?

Yes — we can provide expert assessments, photographic evidence, and written reports to support insurance claims following storm damage, root subsidence, or fallen trees.

Are your tree inspectors qualified and insured?

Absolutely. All inspections are carried out by qualified arborists with relevant certifications (e.g. NPTC, LANTRA, City & Guilds). Waterman Tree Co. is fully insured with public liability cover up to £5 million.

Can tree inspections help prevent subsidence or root-related damage?

Yes. Regular inspections can identify trees at risk of causing root-related issues, especially near foundations or underground utilities. Early intervention — such as root pruning or species replacement — can help prevent costly damage.

Do you offer emergency inspections after storms or high winds?

Yes — if a tree has been damaged in a storm or is suddenly leaning, split, or shedding limbs, we offer priority inspections and emergency response to assess the risk and recommend immediate action.
