How to become a tree surgeon

Tree surgery — climbing arboriculture — is one of the most safety-critical jobs in the green industry. You work at height with a chainsaw, often near buildings, power lines and the public. Employers cannot take you on without certification, which makes the ticket sequence unusually clear. For the wider picture — who employs arborists and how tree surgery, surveying and consultancy differ — read exploring careers in arboriculture.

The certificate ladder

Training is modular and each unit unlocks the next. The commonly required sequence is:

• CS30 — chainsaw maintenance and cross-cutting
• CS31 — felling and processing small trees
• CS38 — tree climbing and aerial rescue
• CS39 — using a chainsaw from a rope and harness
• CS40 and CS41 — dismantling and rigging, needed for larger removals

You do not need all of them on day one. Many people start as a groundsperson with CS30 and CS31, then add climbing units when they are ready. Do not skip aerial rescue: it is the qualification that makes you employable as a climber, because a crew cannot send you up without it.

Starting as a groundsperson

The groundsperson role is the standard entry point. You will feed the chipper, drag brash, set up rigging, control the drop zone and keep the site tidy. It is hard physical work and it teaches you how a crew actually operates before you are responsible for your own safety at height.

What employers look for in a first hire:

• CS30 and CS31, or a willingness to fund them immediately
• A driving licence — most crews need a second driver
• Comfort working outdoors in all weather
• Clear understanding of hazard zones and exclusion areas
• Reliability, because a two-person crew depends on both people turning up

Climbing, then specialising

Once climbing, you will spend years refining technique: accurate pruning cuts, controlled dismantling, rigging systems, and judgement about what a tree can take. From there the usual routes are team leader (planning the job and briefing the crew) or the technical side — tree risk assessment, surveys, planning advice and reports, which normally require a Level 4 qualification or above and professional membership.

Some arborists move into utility or rail arb work, which pays well but demands additional competence and a disciplined approach to procedure.

Safety is the career

This is not a trade where you can improvise. Method statements, LOLER inspections of climbing equipment, rescue plans and a current first-aid certificate are all part of the job, and employers will ask about them at interview. Read working safely in the green industry and machinery and equipment certifications before you start applying.

Is it for you?

Tree surgery suits people who are physically confident, unbothered by heights, and careful rather than fearless. The training costs real money — budget for each unit — but the tickets are yours for life and they travel between employers.
