Tree Surgery Regulations UK: What Arborists Need to Know

Tree surgery is a specialist trade that involves the care, maintenance and removal of trees. The work can include pruning, crown reduction, stump removal, felling dangerous trees and carrying out emergency tree work, often while using chainsaws, heavy equipment and working at height.

Because of the risks involved, tree surgeons and arborists must follow strict UK safety regulations, environmental rules and legal requirements. Failing to meet these duties can lead to serious accidents, fines, legal action and problems with insurance.

Whether you’re carrying out routine tree maintenance or removing a hazardous tree, compliance should be considered before any work begins. In this guide, we’ll explain the key tree surgery regulations in the UK and what arborists need to know before starting a job.

Health and Safety Regulations for Tree Surgeons

Tree surgery is one of the riskier trades out there, which is why getting health and safety right isn’t optional. Whether you’re pruning, removing or replacing a tree, the way in which you work matters just as much as the end result.

Accidents involving chainsaws, falling materials or heights can be severe - it’s one of the reasons DIY tree surgery isn’t recommended, and it’s why the tree surgery industry is so tightly regulated.

There are three main regulations for tree surgeons:

• Health and Safety at Work Act 1974 - This places a legal duty on you to protect your own safety and the safety of anyone affected by your work, such as employees, clients and members of the public. This means planning jobs properly, using the right equipment and making sure risks are controlled.
• Provision and Use of Work Equipment Regulations 1998 - Also known as PUWER, this covers the tools and machinery you use, including chainsaws, wood chippers and stump grinders. All of your equipment must be suitable for the task, maintained properly and only used by someone who’s trained.
• Work at Height Regulations 2005 - These tree surgeon health and safety regulations apply whenever there’s a risk of a fall causing an injury. They require you to avoid working at height where possible, and to use the safest method available if you do need to. This includes using the correct climbing systems, carefully securing anchor points and knowing the safest techniques.

With all of these tree surgery regulations, risk assessment is important. Before starting any job, you need to identify all hazards and put measures in place to control risks.

For example, assessing ground conditions or planning how materials will be lowered safely. Adhering to practical working standards - such as operating chainsaws in line with training and wearing PPE - is non-negotiable, even if the job is a quick and simple one.

Chainsaw Training and Competency Requirements

If you want to use a chainsaw professionally, you need to be competent and properly trained, and there’s a legal expectation on you to use the equipment safely. Under tree surgery regulations, you’re required to make sure that anyone using machinery has received training. This means completing recognised certifications, not just relying on informal experience.

What Does Chainsaw Training Look Like?

Basic training starts with chainsaw maintenance and cross-cutting, and covers how to safely handle, inspect and maintain a saw, along with correct cutting techniques. From there, many tree surgeons move on to more in-depth tree felling qualifications, which enable them to safely fell trees up to a certain size.

If you’re planning to carry out climbing work, you’ll also need aerial chainsaw training. This includes learning how to use a chainsaw safely whilst in a harness. Using a chainsaw at height carries a lot more risk, so training is strict, and it’s not something you can skip.

Training Costs and Considerations

Chainsaw training can also affect how you price work. Quotes for jobs that involve cutting at height or complex methods should reflect the additional skill required. Plus, training comes at a cost, so factor it in when you’re setting up or expanding your business. Courses, assessments and training all need to be part of your ongoing business costs.

Having the right tree surgeon certifications directly affects your ability to work safely, secure contracts and get insurance. In fact, many insurers require proof of qualifications before they agree to cover you, and a lack of recognised training can invalidate a claim.

Tree Preservation Orders and Conservation Areas

Even if a client has requested that you prune, reduce or remove a tree, it’s important to remember that not all trees can be worked on freely. Many trees in the UK are legally protected, and carrying out unauthorised work can lead to serious consequences. It’s your job to check whether restrictions apply before starting any work.

Tree Preservation Orders

Tree Preservation Orders (TPOs) are given by local councils, and they can apply to a single tree, a group of trees or even an entire forest. They're there to protect trees that provide public amenity or environmental value. Once a tree is covered by a TPO, it becomes a criminal offence to cut down, prune, damage or destroy it without permission.

Conservation Areas

As well as TPOs, trees located within conservation areas are also protected. To work on a tree in a conservation area, you’ll need to give the local council at least six weeks’ written notice before starting any work, giving them time to assess whether a TPO should be issued.

This could affect how you schedule and price work, and delays waiting for permission, potential reapplications or changes to the scope of work all need to be considered.

Carrying out unauthorised work on a protected tree can lead to large fines, legal action and damage your reputation as a tradesperson.

Waste Disposal Regulations

Tree surgery generates a fair amount of waste, including branches, logs, woodchippings and stump grindings. This is classed as controlled waste, and there are clear legal responsibilities that set out how it should be handled.

• You’ll need to register as a waste carrier, and failing to hold a valid waste carrier licence can lead to fines or legal action.
• Disposal also needs to be done properly. Branches, logs and woodchippings should be taken to authorised facilities for processing before being reused or properly disposed of.
• Agree with clients what will happen to any waste generated before work begins. Some clients might want to keep logs or woodchips, whereas others would prefer that you handle all of the clearing up.
• Keeping clear records is another important part of compliance, especially for larger or commercial jobs, as you might need proof of where waste has been taken. Having records also protects your business if there are ever questions about illegal dumping or environmental breaches.

Wildlife and Environmental Protection Laws

You need to consider wildlife before you carry out any tree surgery work. Trees often provide habitats for protected species, and disturbing them can be a criminal offence, even during routine jobs like pruning or tree removal.

The wildlife and environmental regulations for tree surgeons are mainly found in the Wildlife and Countryside Act 1981 and the Conservation of Habitats and Species Regulations 2017. These laws protect nesting birds, bats and other wildlife, as well as the places they live.

These regulations prevent you from:

• Disturbing nesting birds during breeding season. If an active nest is found, you’ll need to stop work immediately.
• Working too close to bats. If there are signs of bats or potential roosts, you’ll need to stop work and seek advice.
• Disturbing tree habitats, such as cavities or deadwood.

Before you start any work, carry out a basic check to see if wildlife is present. If it is, you might need to delay or adjust your plans.

Insurance and Liability Requirements

There are a lot of risks that come with tree surgery, so having the right insurance in place is key. Regardless of whether you’re working with a team or as a self-employed tradesperson, you’re responsible for protecting yourself, your staff and anyone affected by your work.

As insurance comes at a cost, it should be treated as a business expense and factored into your budget and pricing.

There are three main types of tree surgery insurance:

• Public liability insurance covers injury to third parties or damage to property.
• Employers’ liability insurance covers workplace injuries.
• Equipment insurance to protect tools and machinery.

Many clients will ask for proof of insurance before confirming any work, especially as employers’ liability insurance is a legal requirement if you employ staff. You might even struggle to win contracts if you don’t have the right cover.

Risk Assessments and Site Safety

Tree surgeon safety starts before any cutting even begins, and it starts with a risk assessment. Assess the condition of the tree - this means checking for decay, deadwood, structural weakness or damage, and identify any potential hazards. For example, overhead cables, nearby roads or public access. With these factors in mind, you can plan the safest approach and choose the right equipment for the job.

You will then need to secure the area you’re working in, which can involve setting up barriers, putting up signs or creating exclusion zones to keep the public at a safe distance. You’ll also need to consider nearby buildings, fences, vehicles and gardens, making sure they’re protected from falling branches.

Taking the time to carry out a risk assessment helps to prevent accidents and avoidable damage. It also helps the job to run smoothly, which can affect how much time it takes, the overall cost and client satisfaction.

Working Near Roads and Public Areas

If tree surgery is being carried out near roads, pavements or other public spaces, and there’s a risk to passing traffic or pedestrians - you’re responsible for keeping everyone safe. This often means creating a traffic management plan, including organising temporary road closures or putting traffic lights in place.

You’ll also need clear warning signs and to install physical barriers, creating a safe working zone and guiding the public away from danger. You might even need to get permission from the local authority before work begins.

Tips for Staying Compliant as a Tree Surgeon

• Stay up to date with current tree surgery regulations and guidance, making sure you understand any changes that could affect how you plan or carry out work.
• Keep all certifications and training up to date, ensuring you remain fully competent and insured for the jobs you do.
• Keep a record of permissions, risk assessments and site checks, so you have clear evidence of compliance if any issues arise.
• Use high-quality PPE and equipment, and make sure everything is fit for purpose.
• Avoid cutting corners to offer cheap work, as this can compromise safety.

Following tree surgery regulations isn’t just about avoiding fines, it also helps to protect your business, workers, clients and the environment you’re working in.
