6 Surprising Truths About Hiring a Tree Surgeon That Could Save You a Fortune

Introduction: The Overhanging Branch Problem

It often starts with a glance out of the window. You notice a branch that seems a little too close to the roof, or that the old oak tree is casting the entire garden into permanent shade. The thought process is usually simple: "I need to get that sorted." For most homeowners, this seems like a straightforward task—find a local tree surgeon, get a quote, and the problem is solved.

The reality, however, is far more complex. Hiring a tree surgeon is not like hiring a painter or a plumber. The process is fraught with hidden legal liabilities, significant safety risks, and counter-intuitive facts where the cheapest option can quickly become the most expensive mistake you'll ever make. The responsibility for legal checks, insurance validity, and even neighbourly disputes often falls squarely on your shoulders, not the contractor's.

Before you make that call, it's crucial to understand the high-stakes nature of the job. This guide will reveal the six most impactful truths about hiring a tree professional—insights that could protect your property, your finances, and your peace of mind.

--------------------------------------------------------------------------------

1. Why That Shockingly High Quote Is Your Best Friend

When quotes for tree work land, the figures can be startling, with costs ranging anywhere from £200 for simple jobs to over £3,000 for complex removals. It's tempting to immediately discard the highest bid. However, in the world of arboriculture, a surprisingly high quote is often a sign of professionalism, while an unusually low one is a major red flag.

The cost is driven by several critical factors. First is the specialised equipment, which can include cranes and mobile elevated work platforms. Second is the high-risk labour; a qualified tree surgeon's day rate can range from £240 to £400 per person. But the most significant component is comprehensive insurance. A professional crew will carry a Public Liability policy of at least £5 million to cover any potential damage to your property or a neighbour's.

A quote that seems "too good to be true" almost certainly is. It likely signals that the contractor is cutting corners on essential overheads like safety protocols, formal qualifications, or, most dangerously, their insurance. Opting for the cheapest bid might save you money upfront, but it could expose you to catastrophic financial liability if an accident occurs. Think of a professional quote not as an expense, but as an investment in safety and peace of mind. But as you'll see next, even the most expensive professional can't protect you from the single biggest legal responsibility—one that falls entirely on you.

2. The Biggest Legal Responsibility Is Yours, Not Theirs

Here is one of the most surprising and critical facts for homeowners: you, not the contractor, are legally responsible for checking if a tree is protected. Before any work begins, you must determine if the tree is covered by a Tree Preservation Order (TPO) or is located within a Conservation Area (CA).

The consequences for failing to get the required permission from your local council are severe. Unauthorised work can lead to fines of up to £20,000 in a magistrates' court. If the case is serious enough to be tried in a Crown Court, the fines are potentially unlimited. A reputable tree surgeon will often assist with these checks, but the law is unequivocal: the legal buck stops with the homeowner.

Many homeowners are also caught off-guard by the timelines involved. You must give your council six weeks' notice for work on trees in a Conservation Area and wait up to eight weeks for a decision on a TPO application. Another surprising liability rests with you: managing neighbourly relations. If work is being done on branches that overhang a neighbour's property, the client—that is, you—is responsible for informing them of the proposed work and assumes all liability for any disputes that may arise.

3. The "Dead and Dangerous" Exemption Is a Risky Gamble

There is a well-known exemption that allows for work on a protected tree without formal consent if it is dead, dying, or immediately dangerous. While this sounds like a convenient loophole, relying on it is a significant legal gamble for the homeowner.

Using this exemption is a "subjective legal judgement." If you proceed with removal and the local council later challenges your assessment that the tree posed an imminent danger, you are the one who is legally liable. The burden of proof falls on you to justify the work.

To gain maximum legal protection, the expert recommendation is clear: before any work starts, you should commission an independent arboricultural consultant to provide a written survey. This report, which typically costs between £250 and £420, will formally certify the tree's hazardous condition. This documentation provides critical liability protection against any potential challenge from the authorities and is a small price to pay for legal certainty.

4. A National Tree Crisis Makes Waiting More Expensive

A fungal disease called Ash Dieback (Hymenoscyphus fraxineus) is sweeping across the country, creating a national crisis for one of Britain's most common native trees. For homeowners, this national crisis creates a personal financial time bomb: the longer you wait to deal with an infected ash, the more you will pay.

The scale of the problem is immense, with the disease predicted to kill up to 80% of ash trees across the UK. As one report notes:

"Ash dieback is predicted to cost £15 billion in Britain."

For a homeowner with an infected ash tree, waiting is the worst possible strategy. As the disease progresses, the wood becomes structurally unpredictable and brittle. This is "significantly increasing the hazard and complexity of felling." A tree that could be removed through a planned, methodical process becomes a high-risk, emergency operation requiring more time, more specialised equipment, and a larger crew—all of which dramatically inflates the final bill. Proactive, scheduled removal is not only safer but also significantly more cost-effective than waiting for a crisis.

5. You Have to Ask to Keep Your Own Firewood

After a tree has been expertly felled and dismantled, you're left with a considerable amount of wood. It seems logical that this wood now belongs to you, ready to be seasoned for firewood or chipped for garden mulch. However, this is a mistaken assumption that catches many homeowners by surprise.

Many tree surgeons will automatically quote for the removal and disposal of all debris from the site. Unless you state your intentions clearly from the outset, they will assume the wood is to be taken away. If you want to keep the logs for a fire, the woodchips for mulch, or even larger branches for garden projects, you must be explicit about this before the work starts.

The good news is that most contractors are perfectly happy to leave the wood for you. If agreed upon in advance, they will often stack the logs neatly for you. Just be sure to communicate your wishes clearly to avoid any misunderstanding or potential extra charges.

--------------------------------------------------------------------------------

6. Their Insurance Might Be Worthless Without the Right Qualifications

Most homeowners know to ask a contractor if they have insurance. But here's the hidden catch that very few think to check: that insurance policy may be completely invalid if the workers on your property are not properly certified for the job they are doing.

High-value Public Liability policies—the ones that protect your home from damage—are almost universally contingent on the contractor using appropriately certified personnel. This means holding specific qualifications, such as NPTC units (nationally recognized certificates of competence for specific skills) like CS30 for chainsaw maintenance, CS31 for felling small trees, and CS38/39 for climbing and aerial rescue.

The risk for the homeowner is immense. If an accident occurs and the operative is found to be unqualified for the task they were performing, the insurance company may reject the claim. This could leave you, the property owner, personally exposed to liability for damages. To mitigate this risk, prioritize hiring an Arb Approved Contractor (ArbAC). This scheme, run by the Arboricultural Association, is the UK industry standard for quality. As contractors who have achieved the standard note:

"In an industry plagued by cowboys and rogue traders, Arb Approved status gives you the client, peace of mind knowing you are hiring a professional company."

Conclusion: A Final Thought on the Tree in Your Garden

Hiring a tree surgeon is clearly a high-stakes decision that requires far more diligence than most people realize. It's a process where the cheapest option is rarely the best, and where the greatest legal responsibilities often lie with the homeowner. Understanding the true costs, the legal duties, and the crucial link between qualifications and insurance is the only way to protect yourself from unforeseen financial and legal disasters.

A professional, highly-qualified, and fully insured tree surgeon provides more than just a service; they provide a shield of liability and a guarantee of safety. Now that you know the hidden risks, will you look at that tree in your garden—and the professional you hire to care for it—in a new light?
