Arborist / Tree Surgeon
Safety is the defining discipline of this trade. Arboriculture consistently appears in statistics as one of the higher-risk occupations in the UK. Working at height with chainsaws, in a living and structurally unpredictable environment, demands absolute discipline around safe working practices. The industry takes this seriously, and so should anyone entering it. Cutting corners in tree work kills people.
What is it?
An Arborist, commonly known as a Tree Surgeon, is a skilled professional who plants, maintains, manages, and removes trees in a safe, informed, and environmentally responsible way. Arborists work across an enormous range of environments - from private gardens and urban streets to forests, parks, national estates, and utility corridors.
It is one of the most physically demanding, technically skilled, and genuinely varied outdoor trades available. No two trees are the same, no two jobs are identical, and the combination of working at height with powerful machinery in living, unpredictable natural environments means that skill, judgement, and safety awareness matter enormously.
It is also, for those who love the outdoors and working with nature, one of the most rewarding trades there is.
What would you actually do?
Depending on your specialism and employer, you could be:
Climbing trees using ropes, harnesses, and specialist climbing equipment
Carrying out crown reductions, reshaping, and formative pruning
Removing deadwood and making trees safe without felling them
Felling trees of all sizes safely using chainsaws and controlled techniques
Operating aerial work platforms and mobile elevated work platforms (MEWPs)
Chipping brash and processing timber using wood chippers and chainsaws
Carrying out tree surveys and producing written reports on tree condition and risk
Planting and establishing new trees in urban and rural settings
Managing woodland and carrying out coppicing, thinning, and habitat work
Advising clients on tree health, planning constraints, and management options
Working alongside local authorities, utilities, and developers on tree management programmes
Aerial rescue qualification is non-negotiable for climbers. Before you climb professionally you must be able to rescue an incapacitated climber from the canopy. This is not optional and any reputable employer will require it.
Career Paths
Climbing arborist - the core of the trade, working in the tree canopy using rope and harness systems to carry out pruning, deadwooding, and dismantling work. The most skilled and physically demanding aspect of the job.
Ground worker - supporting the climbing arborist from the ground, processing brash, operating the chipper, managing ropes, and keeping the work zone safe. The starting point for most people entering the trade.
Tree feller - specialist felling of trees in confined spaces, along roadsides, and in woodland settings using chainsaw techniques and rigging systems.
Aerial rescue and utility arborist - working near overhead power lines and utility infrastructure, requiring additional specialist training and clearances.
Consulting arborist - carrying out tree surveys, producing tree reports, advising on planning applications, and acting as an expert witness. A more office-based route for experienced arborists who move into consultancy.
Local authority arborist - managing the tree stock on public land, streets, and parks for a council or local authority. More structured hours and greater focus on surveying and planning than private sector climbing work.
Woodland manager - overseeing woodland habitats, carrying out coppicing, thinning, and habitat management, and managing the commercial or conservation use of woodland.
Tree planting specialist - working on large-scale tree planting programmes, increasingly common as government and corporate tree planting targets drive significant demand for establishment and aftercare work.
Is it right for you?
You might suit arboriculture if you:
Love working outdoors in all weathers and have no desire to be office or workshop-based
Are comfortable, ideally excited, by working at height
Are physically fit, strong, and have good stamina for demanding outdoor work
Have a genuine interest in trees, ecology, and the natural environment
Enjoy problem-solving under pressure, every tree presents different challenges
Take safety seriously and are disciplined about following procedures around inherently dangerous equipment and situations
Want genuine variety -- different sites, different trees, different challenges every day
It might not suit you if working at height causes genuine anxiety rather than manageable caution, or if cold, wet, muddy outdoor conditions in winter feel intolerable rather than acceptable. Arborists work outside every day of the year regardless of weather.
The trade has a strong professional community. The Arboricultural Association, ISA UK Chapter, and various regional networks offer CPD events, competitions, and connections. The climbing and aerial rescue competition circuit - including events like the ISA UK Tree Climbing Championship - is a genuine and respected part of the culture.
Skills you will build
Chainsaw operation and maintenance - from ground cutting to aerial chainsaw work
Rope climbing and rope access techniques for working in the tree canopy
Rigging - using ropes, pulleys, and friction devices to control and lower sections of tree safely
Tree identification - recognising species, understanding their growth habits and structural characteristics
Tree health and hazard assessment - identifying decay, disease, structural weakness, and risk
Safe use and operation of wood chippers, stump grinders, and MEWPs
Tree survey and report writing for planning and management purposes
Understanding tree law - Tree Preservation Orders, conservation areas, and planning conditions
Working safely near overhead power lines and underground utilities
Team communication and site management
How do you get in?
Apprenticeship - an Arborist apprenticeship at Level 2 is available and combines practical on-site work with college attendance. Takes around two years and covers climbing, chainsaw operation, and tree work fundamentals. A strong starting point that gets you into a working team from the beginning.
College course - a Level 2 Certificate or Diploma in Arboriculture provides the core technical knowledge and practical skills. Writtle University College, Merrist Wood, Myerscough College, and a number of other specialist land-based colleges offer strong arboriculture programmes.
Lantra and NPTC qualifications - many people enter the industry through Lantra Awards and NPTC (National Proficiency Tests Council) unit qualifications in chainsaw operation, climbing, and aerial rescue rather than through a full college diploma. These unit qualifications are the industry's practical currency and are recognised by all employers.
Direct entry as a groundworker - starting on the ground crew of an arborist company - raking up, chipping brash, and learning the ropes - is a completely valid and very common entry point. Many successful climbing arborists began this way, building chainsaw and climbing qualifications while working.
Forestry and land-based routes - those coming from forestry, conservation, or countryside management backgrounds often transition into arboriculture, bringing related skills and qualifications with them.
Tree Preservation Orders and planning law are part of the job. Many trees in urban and suburban environments are legally protected. Working on a protected tree without consent is a criminal offence. Understanding the basics of tree law is important for anyone working in private gardens or urban settings.
Qualifications to know about
Level 2 Certificate / Diploma in Arboriculture - the core college qualification covering tree biology, identification, pruning, and chainsaw use
Level 3 Diploma in Arboriculture - for those progressing to supervisory, consultancy, or specialist roles
NPTC / Lantra Chainsaw qualifications (CS30, CS31, CS38, CS39, CS41) - the practical chainsaw unit awards covering felling, snedding, cross-cutting, and aerial chainsaw work. Essential for anyone working with chainsaws professionally
NPTC / Lantra Climbing and Aerial Rescue (CS38 / CA1) - the qualification covering safe climbing and aerial rescue procedures. Required before climbing professionally
NPTC Woodchipper operation - required for operating wood chippers professionally
MEWP (Mobile Elevated Work Platform) qualification - required for operating cherry pickers and aerial platforms
Stump grinding qualification - required for operating stump grinding equipment
Aerial Rescue qualification - a critical safety qualification covering how to rescue an incapacitated climber from a tree
ARB Approved Contractor scheme - a quality mark awarded to arborist companies; working for an ARB Approved Contractor is a good indicator of professional standards
