If a contractor turns up, glances at a large tree for two minutes and says, "We can take it down tomorrow," that should give you pause.

Tree work is not the same as general garden maintenance. A poor decision can damage the health of the tree, create risk for people and property, and leave you with a larger bill later. The right arborist should be able to explain what needs doing, why it needs doing, and how the work will be carried out safely.

For homeowners, landlords and property managers, the best approach is simple: ask better questions before you agree to any work.

The best questions to ask arborist before hiring

The best questions are not designed to catch anyone out. They help you understand whether you are speaking to a qualified professional or somebody offering quick tree cutting with little thought for safety, standards or long-term results.

A good arborist should welcome these conversations. Clear answers usually point to clear working practices.

1. What work do you actually recommend, and why?

This is the starting point. You want more than a price for "sorting the tree out". Ask what the problem is, what outcome they are aiming for, and whether there is more than one suitable option.

Sometimes a crown reduction is appropriate. Sometimes crown lifting or selective pruning is enough. In other cases, a tree may be dead, unsafe or too badly diseased to retain. A trustworthy contractor will talk you through the reasoning instead of pushing straight to removal.

That matters because tree work is often a balance. Removing too much can stress a healthy tree. Doing too little may leave a hazard in place. The answer depends on the species, condition, location and surrounding structures.

2. Are you fully qualified and trained for this type of work?

This question should never feel awkward. Chainsaws, climbing work, rigging and aerial dismantling all carry serious risk, and formal training matters.

Ask what qualifications the team holds and whether they have relevant competency certificates for tree work. In the UK, recognised training and certification such as NPTC City & Guilds shows that the contractor has been assessed properly. CSCS cards and health and safety training are also strong signs that you are dealing with a professional outfit rather than casual labour.

If the work is near buildings, roads, fences or tight access points, experience becomes even more important. The more complex the site, the less room there is for guesswork.

3. Will the work be carried out to British Standards?

Not every customer knows to ask this, but it is one of the most useful questions on the list.

For pruning and general tree work, BS3998 is the recognised benchmark in the UK. An arborist who works to British Standards should be able to explain how that shapes the approach, from pruning cuts to the amount of crown removed.

This matters because there is a clear difference between careful tree surgery and overcutting. A contractor following proper standards is more likely to preserve tree health while still addressing safety and management concerns.

Questions that reveal how safe and professional they are

Price matters, but safety, insurance and planning matter just as much. If a contractor is vague here, that is usually a warning sign.

4. Are you insured for tree work?

Ask whether they carry public liability insurance and, where relevant, employers' liability insurance. Tree work is high-risk by nature. If a branch damages a roof, vehicle, fence or neighbouring property, you need confidence that the business is properly covered.

The key point is not just having insurance in name. It should be suitable for arboricultural work, not a generic policy that may not reflect climbing, cutting or dismantling operations.

5. How will you carry out the work safely on my site?

A proper arborist should be able to describe the method in practical terms. That might include climbing techniques, lowering ropes, sectional dismantling, traffic or pedestrian management, and how they will protect nearby buildings, sheds, greenhouses or garden features.

You do not need a lecture full of jargon. You do need enough detail to see that they have thought the job through. If access is awkward, if the tree overhangs a conservatory, or if it is close to a public footpath, the plan should reflect that.

6. Do I need permission before work starts?

This is a very important one. Some trees are protected by Tree Preservation Orders, and others may sit within a conservation area. In those cases, work may require permission or formal notice.

A reliable arborist should raise this issue early. They should not encourage you to ignore it and "just get it done". If there is any doubt, they should help you establish the tree's status before work begins.

That protects you as much as the contractor. Unauthorised work on a protected tree can lead to serious consequences.

Questions about price, scope and what happens afterwards

A cheap quote can become expensive very quickly if the scope is unclear. Good contractors are usually precise about what is included.

7. What exactly is included in the quote?

Ask for clarity on the full scope of works. Does the price include cutting, lowering, waste removal, stump grinding, hedge reinstatement, site tidy-up and disposal of timber and chip? Or is it only the cutting itself?

This is where misunderstandings often happen. One quote may seem higher, but include all waste clearance and a full tidy. Another may look cheaper while leaving you with logs, brash and a damaged lawn.

A fair quote is not always the lowest one. It is the one that clearly matches the work you actually need.

8. Will you remove all waste and leave the site tidy?

This sounds basic, but it is worth asking directly. Tree work creates a surprising amount of material. Branches, timber, sawdust and woodchip can quickly overwhelm a garden or commercial site.

Professional contractors should explain what happens to the waste and whether it will be recycled responsibly. That is often a mark of a business that takes both its workmanship and environmental responsibilities seriously.

9. Is stump removal necessary, or can it stay?

Not every tree removal needs stump grinding afterwards. Sometimes the stump can remain without causing a problem. In other situations, it may create trip hazards, interfere with replanting, attract regrowth or get in the way of landscaping.

A good arborist will explain the trade-off rather than selling extra work by default. If you are planning fencing, turfing, paving or replanting, that context matters.

The best questions to ask arborist about tree health

If your concern is disease, storm damage or a tree that has started to look sparse or uneven, you need more than a cutting quote. You need a proper assessment.

10. Is the tree unsafe, unhealthy, or simply overgrown?

These are not the same thing. An overgrown tree may need management, but that does not mean it is dangerous. A tree can also look full and green while having serious structural defects.

Ask the arborist to separate appearance from risk. Are there dead branches, decay pockets, fungal issues, included bark unions, root concerns or signs of movement? Or is the issue mostly shade, clearance or routine maintenance?

The answer helps you avoid unnecessary work while still acting quickly where there is a genuine hazard.

11. Can the tree be retained, or does it need removal?

A careful arborist does not default to felling. If a tree can be managed safely through pruning, reduction, cable bracing or monitoring, that should be part of the conversation.

Of course, some trees do need to come down. Dead, structurally unsound or badly diseased trees can become dangerous, especially near homes, driveways or public spaces. The point is that removal should be justified, not treated as the automatic answer.

This is often where local knowledge helps too. In Worcestershire, many properties have mature trees close to boundaries, roads and older buildings, so the right recommendation needs to account for both safety and long-term management.

12. What should I expect after the work is done?

This final question is often overlooked. Ask how the tree is likely to respond, whether follow-up maintenance may be needed, and what signs to watch for afterwards.

For example, some species respond vigorously to pruning, while others need a lighter touch. A tree that has had remedial work after storm damage may need monitoring over time. If a tree is removed, you may want advice on replanting the space sensibly.

A good contractor will not just finish the cut and disappear. They will help you understand what happens next.

Choosing the right contractor with confidence

If you ask these questions and the answers feel rushed, defensive or unclear, trust that instinct. Tree work should feel measured and professional from the first conversation.

The right arborist will explain things plainly, respect your property, price the work fairly and put safety first. They should also be comfortable discussing qualifications, insurance, standards and permissions without hesitation. That is what gives customers confidence, especially when the work is complex or urgent.

At STN Trees & Landscaping, that assessment-led approach matters because customers are not just paying for someone to cut branches. They are paying for informed judgement, compliant working practices and a team that treats their property with care.

When you know the best questions to ask, it becomes much easier to spot the difference between a proper arborist and somebody simply offering to cut first and think later.
