For many people starting a career in tree surgery, climbing is the stage they are most interested in. It is also one of the stages where timing matters most.
Tree climbing is not just about confidence at height. It involves rope and harness systems, rescue planning, communication with ground staff, equipment checks and safe movement through the canopy. Before moving into aerial work, learners usually need a solid foundation in site safety, ground-based tree work and, where relevant, chainsaw competence.
This guide explains what tree climbing courses involve, when you may be ready to move into aerial work, and how climbing and aerial rescue fit into the wider arboriculture training pathway.
Tree climbing courses are designed for people who need to work safely in trees as part of arboriculture or tree surgery operations. They are not the same as recreational climbing. The focus is on safe access, movement in the canopy, rope and harness systems, rescue procedures and working as part of a professional team.
A typical tree climbing and aerial rescue course may cover:
The aim is to help learners develop the skills needed to climb safely and respond if another climber gets into difficulty.
HSE guidance on tree-climbing operations highlights the importance of safe systems of work, risk assessment and recognised industry guidance for arboriculture tree work at height.
For most beginners, tree climbing is not the first step.
Many people start with ground-based chainsaw work, site support or another outdoor role before moving into climbing. This gives you time to understand how tree surgery sites operate, how teams communicate and how risk is managed.
Ground-based experience can help you learn:
Someone completely new to the industry may be better starting with chainsaw training courses or a ground-based route before booking a climbing course. The wider route into training, ground-based experience and progression is covered in more detail in our guide on how to become a tree surgeon.
Before moving into tree climbing, it is useful to have a strong understanding of basic site safety and ground-based operations.
You do not necessarily need years of experience before starting a tree climbing course, but you should be ready for a practical, physically demanding training environment. Climbing is a professional skill, not just the next exciting step in the career path.
Before aerial work, many learners benefit from training or experience in:
For people building a tree surgery career, CS30 and CS31 chainsaw courses are often part of the early pathway. These terms are still widely used by employers and learners when referring to chainsaw maintenance, cross-cutting and small-tree felling.
If an employer has asked for a specific chainsaw ticket and you are unsure what they mean, it is worth checking whether they are referring to an older CS unit, a current qualification title or a particular certificate of competence.
Aerial rescue is a key part of professional tree climbing training. If someone is working at height, the team must be prepared to respond if that person becomes injured, trapped or unable to descend.
This is one of the reasons tree climbing is treated as a professional skill. A climber is not working in isolation. The whole team needs to understand communication, rescue planning and emergency procedures.
HSE guidance for arboriculture contractors also points to relevant certificates of competence, including chainsaw use, tree climbing and aerial rescue, chippers and MEWPs, when checking contractor competence.
For learners, this means aerial rescue should not be seen as an optional extra. It is part of preparing to work safely in a tree surgery team.
There is no single point when every learner is ready. The right time depends on your experience, confidence, fitness and career goals.
You may be ready to consider a tree climbing course if:
You may need more preparation if you are not confident with basic site safety, have no experience around tree work teams, or are unsure whether you are comfortable working at height.
If you are already employed in grounds maintenance, forestry, landscaping, utilities or estate work, your existing outdoor experience may help. However, aerial tree work still requires specific training.
A simple way to think about progression is to move from ground-based competence into aerial access, then into more advanced aerial chainsaw work.
Stage | Training focus | Why it matters |
Starting out | Chainsaw maintenance and cross-cutting | Builds safe ground-based chainsaw skills |
Ground-based progression | Felling and processing small trees | Supports practical tree work from the ground |
Climbing foundation | Tree climbing and aerial rescue | Helps learners access, move and respond safely in the tree |
Aerial chainsaw progression | Using a chainsaw from a rope and harness | Supports chainsaw use while positioned in the tree |
Ongoing competence | Refresher training | Helps existing operators maintain safe working habits |
The exact order may vary depending on your current experience and employer requirements, but most learners should avoid jumping straight into advanced aerial chainsaw work.
Once you have completed tree climbing and aerial rescue training, the next step may be further experience, supervised practice or additional training.
For some learners, the next major progression point is using a chainsaw from a rope and harness. This is a more advanced stage because it involves chainsaw use while working in the tree.
Before reaching that point, you need a strong foundation in climbing, positioning, communication and rescue procedures. You should also understand the difference between being able to climb a tree and being ready to carry out chainsaw work in that environment.
HSE guidance on chainsaw operator training says workers using a chainsaw at work should be competent and should have appropriate training for the type of work they are required to do.
It depends on the course, your experience and what you want to do next.
A tree climbing and aerial rescue course is focused on climbing and rescue, not necessarily chainsaw use in the tree. However, if your aim is to progress into tree surgery, ground-based chainsaw training is often part of the wider pathway.
For many learners, chainsaw maintenance and cross-cutting comes before more advanced arboriculture work. Felling and processing small trees may also be relevant before progressing further.
The main tree surgeon qualifications usually build from ground-based chainsaw skills into felling, climbing, aerial rescue and, later, more specialist chainsaw work.
One common mistake is treating climbing as the first step into tree surgery. Climbing is important, but it works best when it builds on a wider understanding of tree work, site safety and ground operations.
Another mistake is assuming that climbing automatically means you are ready to use a chainsaw in the tree. These are different stages. Tree climbing and aerial rescue training helps you access and move within the tree safely. Aerial chainsaw work requires further competence.
Learners can also underestimate the physical and mental demands of climbing. Tree climbing requires strength, stamina, coordination and confidence at height. It also requires patience and attention to detail.
Finally, some people focus only on the climber and forget the team. Good aerial work depends on ground staff, communication, equipment checks and rescue planning.
Tree climbing courses may be suitable for:
They may also suit people who have already completed ground-based chainsaw training and want to move towards more specialist arboriculture work.
If you are completely new to tree work, it may be worth starting with a broader introduction to chainsaw and ground-based training before moving into climbing.
Do I need experience before taking a tree climbing course?
You do not always need years of experience, but you should be prepared for practical, physical training and have a good attitude to safety. Some ground-based tree work or chainsaw experience can be helpful before moving into climbing.
Is tree climbing the same as aerial rescue?
No. Tree climbing is about safe access and movement in the tree. Aerial rescue is about being able to respond if a climber gets into difficulty. In professional arboriculture, the two are closely linked because rescue planning is essential.
Can I use a chainsaw after a tree climbing course?
Not automatically. Tree climbing and aerial rescue training does not mean you are ready to use a chainsaw in a tree. Using a chainsaw from a rope and harness is a separate progression stage and requires further training.
What should I do before learning to climb trees professionally?
Many learners start with chainsaw maintenance, cross-cutting, felling and ground-based tree work. This helps you understand tree surgery sites before moving into aerial work.
Are tree climbing courses only for tree surgeons?
No. Tree climbing courses may also be useful for arborists, trainee arborists, grounds maintenance workers, forestry workers, estate teams, utility vegetation teams and employers training staff for tree-related work.
How fit do you need to be for tree climbing?
Tree climbing is physically demanding. You need a reasonable level of strength, stamina and mobility, as well as confidence working at height. Good technique matters, but fitness and focus are still important.
What comes after tree climbing and aerial rescue?
The next step may be supervised experience, further climbing practice or training in using a chainsaw from a rope and harness. The right route depends on your experience and the work you need to carry out.
