How to Choose a Qualified Tree Surgeon in Lancashire

Introduction

I’ve been climbing trees professionally for over eight years now, across both the UK and New Zealand, and if there’s one thing that still catches people out again and again, it’s that here’s no legal protection on the title “tree surgeon” in this country. Anyone can print some business cards, buy a chainsaw, and start calling themselves one tomorrow. No qualifications required. No insurance required. No accountability if something goes badly wrong up your tree or on your roof.

Most homeowners don’t find this out until it’s too late, usually standing in their garden looking at a half-finished job, or a tree that’s been butchered rather than pruned, wondering how they ended up here. I’ve seen it more times than I’d like across Preston, Leyland, and the wider Lancashire area, and it’s honestly one of the things that frustrates me most about this trade. Good, careful, properly trained arborists get lumped in with rogue traders who’ve done a genuine disservice to the industry and, worse, to the people who trusted them with something as significant as a mature tree on their property.

So I wanted to put together something genuinely useful. This article is not a sales pitch dressed up as advice, but the actual questions I’d want a friend or family member to ask before they let anyone near their trees. Some of this comes from training and standards. A fair bit of it comes from the jobs I’ve personally been called out to fix afterwards.

Why This Matters More Than People Realise

Tree work sits in a strange spot. It’s genuinely dangerous, the Health and Safety Executive consistently ranks arboriculture among the more hazardous trades in the UK, and I don’t think that surprises anyone who’s actually watched a large limb come down. And yet, at the exact moment you’re deciding who to let do it, there’s almost nothing stopping an unqualified person from turning up and taking the job.

That combination is what makes the wrong choice so costly, and I don’t just mean financially:

1. Personal injury to the person doing the work, to you, or to anyone nearby, if the job isn’t carried out to a recognised, controlled method.
2. Property damage to your home, your neighbour’s fence, a car parked on the drive, with genuinely no route to compensation if the contractor wasn’t properly insured in the first place.
3. Damage to the tree itself that can’t be undone. I’ve lost count of the number of times I’ve been called out to a tree that’s been “topped”, hacked back hard at right angles rather than properly pruned, and had to explain that the regrowth coming through now is weakly attached and will likely need managing, or removing, for the rest of that tree’s life.
4. Legal exposure that lands on you, not them. If a tree turns out to be protected by a Tree Preservation Order or sits inside a conservation area, it’s usually the landowner who’s on the hook, not necessarily whoever swung the chainsaw.
5. No comeback at all if it goes wrong. An uninsured operator who damages your property, or gets hurt on your land, can leave you covering costs that a five-minute insurance check would have avoided entirely.

I don’t say any of this to scare people as most tree work goes perfectly well, and there are plenty of genuinely good tradespeople out there. I say it because a bit of due diligence up front, which takes maybe ten minutes, is the difference between a smooth job and a genuinely stressful, expensive mess.

Qualifications Worth Checking For

This is the part I’d genuinely encourage you to be a bit nosy about. None of what follows is complicated or gatekept information, it’s exactly what any of my own team could show you on request, and what I’d want to see myself before letting someone loose on a tree in my own garden. A quick look at four things tells you almost everything you need to know about whether you’re dealing with a trained professional or someone learning on the job at your expense.

1. NPTC or Lantra Awards certificates of competence

This is the baseline, full stop. NPTC (now run through City & Guilds) and Lantra Awards are the two bodies that certify chainsaw and aerial work competence in this country. I’m talking about units covering chainsaw maintenance and crosscutting, felling, climbing and aerial rescue, and working from a rope and harness. Any genuine professional will carry a card with these on it and show you without a second thought, I certainly wouldn’t take offence if someone asked to see mine, and neither should anyone else in this trade.

2. A relevant diploma or certificate in arboriculture

Beyond the practical chainsaw units, something like a Level 2 or 3 Diploma in Arboriculture tells you the person actually understands tree biology, disease, and long-term management, not just how to safely bring a limb down, but whether that limb needed to come down in the first place. That distinction matters more than people realise.

3. Arboricultural Association membership or ARB Approved Contractor status

The Arboricultural Association is the industry’s professional body, and ARB Approved Contractor status means a company has been independently assessed against a defined standard, rather than just claiming one. It’s a genuinely useful shortcut if you don’t fancy checking every individual certificate yourself.

4. Work carried out to BS 3998 British Standard 3998:2010

The above is the benchmark for how tree work is actually supposed to be carried out in this country. Ask directly whether the company works to it. A professional operation will answer that without missing a beat, because it’s simply how they already do things.

None of these on their own guarantee a perfect job, nothing ever fully does, tree work has too many variables for that. But together, they tell you the person in front of you has actually been trained, assessed, and is accountable to a recognised standard rather than just their own opinion of their ability. That’s worth far more than it sounds.

Insurance: The Bit I’d Never Compromise On

If I had to boil this whole guide down to one single check, it’d be this one. Qualifications tell you someone knows how to do the job safely. Insurance tells you what happens if, despite that, something still goes wrong, because in this trade, even with the most careful operator, things still can. There are two policies worth asking about specifically.

1. Public liability insurance, covering damage to your property or a third party’s if something goes wrong during the work. I’d want to see a minimum of £2 million for domestic jobs, more for larger commercial sites.
2. Employers’ liability insurance, covering the contractor’s own staff if they’re injured while working on your property. If someone without this cover gets hurt on your land, you can find yourself unexpectedly tangled up in that claim.
3. Ask to actually see the certificate, not just be told it exists. Any legitimate operator will produce this on request, no fuss. If you get hesitation, vague answers, or a “don’t worry about that”, that’s your answer right there.

I’ll be honest, this is the one area where I have zero patience for excuses. Everything else on this list is a matter of degree, more experience is better than less, a diploma adds to NPTC rather than replacing it. Insurance isn’t like that. Either it’s in place and current, or it isn’t, and if it isn’t, you’re the one left exposed, not them.

The Red Flags I’d Personally Walk Away From

Over the years I’ve picked up a fairly short mental list of things that if I see or hear them, they tell me everything I need to know before a single cut’s been made. None of these are subtle once you know to look for them, and most of them show up before any work has even started, which is exactly the point. The earlier you spot one, the easier it is to simply walk away.

1. Cash-only pricing, especially if it’s pushed as a “discount” for paying that way.
2. No written quote. A proper quote follows an actual site visit and comes to you in writing, itemised, with the company’s name and contact details on it, not a number shouted from the pavement.
3. Reluctance to show insurance or qualification documents, or vague, deflecting answers when you ask directly.
4. Cold-calling after a storm, offering to sort your storm damage there and then. This is a genuinely common tactic used by unqualified operators cashing in on people’s panic. We’ve written more about the pattern in our emergency storm damage guide, because it happens often enough to be worth its own explanation.
5. No mention of a waste carrier’s licence. Legally removing tree waste requires one, and it’s a fair question to ask if a large amount of material is being taken off site.
6. Pressure to decide on the spot, or discouragement from getting a second quote. A confident, capable contractor has no reason to rush you.
7. Turning up without proper PPE, including helmet, eye and ear protection, chainsaw trousers, appropriate climbing or access kit. If it looks like someone’s Saturday side hustle, it usually is.

None of these on their own are necessarily damning, plenty of decent people are just a bit disorganised about paperwork. But two or three of these together, especially the insurance and quote-in-writing ones, is where I’d stop the conversation and look elsewhere. Trust your gut here, if something feels off before the work’s even started, it rarely gets better once it has.

The Questions I’d Ask, If It Was My Garden

If you take nothing else from this guide, take this list. Print it, screenshot it, whatever works, as these are the exact questions I’d want asked of me if I were quoting for a job, and any tree surgeon worth hiring will answer every one of them without a flicker of hesitation.

1. Can I see your NPTC or Lantra certificates?
2. Can you show me proof of current public and employers’ liability insurance?
3. Do you work to BS 3998?
4. Will I get a written, itemised quote after you’ve actually seen the site?
5. Will you check whether my tree is protected by a TPO or sits in a conservation area before starting?
6. Do you hold a registered waste carrier’s licence?
7. Have you got examples or references from similar jobs nearby?

If any of those get you a vague or defensive answer, that’s worth listening to. I’ve written a bit more on this distinction in our guide on Tree Surgeon vs Arborist, which digs into why the two terms actually mean quite different things, even though people use them interchangeably.

Why the Cheapest Quote Isn’t Always the Cheapest Option

I understand the pull of the lowest number on the page, I really do. But it’s worth asking what that price is quietly leaving out. An uninsured, unqualified operator working well under the going rate isn’t absorbing that difference out of generosity, they’re simply not carrying the training, insurance, and compliance costs that a legitimate business has to factor into every quote. When something does go wrong, and across enough jobs, eventually something does, that missing cost doesn’t just disappear. It lands on you. I’ve written more about what a fair, professional quote actually includes in our guide on how much do tree surgeons charge, if you want the fuller breakdown.

Hiring a Tree Surgeon in Lancashire?

If you’d like a straightforward, written quote from a fully insured, NPTC-qualified team working to BS 3998, get in touch and tell me a bit about the job. I’m always happy to show my certifications and insurance before anyone books anything, with no pressure, no cash-only deals, no surprises. That’s genuinely how I’d want to be treated if it was my tree.
