How to Start a Tree Surgery Business in the UK

Tree surgery — or arboriculture — is a skilled, physically demanding trade with strong demand from homeowners, local authorities, property developers, and land managers. The work involves significant risk, making qualifications and insurance particularly important.

Qualifications

Tree surgery is one of the more qualification-heavy trades:

• NPTC (now City & Guilds) chainsaw certificates — legally required for anyone using a chainsaw at work:
  • CS30/31 — chainsaw maintenance and cross-cutting
  • CS38 — tree climbing and aerial rescue
  • CS39 — use of a chainsaw from a rope and harness
  • CS40/41 — tree felling and related operations
• Aerial tree rigging certificates — for lowering sections of trees safely
• First aid at work — essential given the risk level
• Chipper and stump grinder operation — NPTC certificates
• Working at height training
• Driving licences — Category C1 or C for larger vehicles and chipper trailers

Professional Bodies

• Arboricultural Association (AA) — the leading UK professional body. Approved Contractor status demonstrates quality and compliance.
• ISA (International Society of Arboriculture) — Certified Arborist credential

Sole Trader or Limited Company?

Most tree surgeons start as sole traders. A limited company provides liability protection, which is particularly relevant given the risk profile of the work. Consider incorporating as you grow.

Registering with HMRC

Register for Self Assessment within three months. VAT at £90,000 — tree surgery businesses can reach this threshold reasonably quickly, especially with commercial and local authority contracts.

Tree surgery services are standard-rated for VAT.

Insurance

Tree surgery carries high risk, making insurance critical and more expensive than many trades:

• Public liability — minimum £5–10 million. Covers damage to property (falling branches, property damage) and injury to third parties.
• Employers' liability — legally required if you employ anyone, even casual labour
• Professional indemnity — if you provide tree surveys or consultancy
• Equipment insurance — chainsaws, chippers, stump grinders, vehicles
• Vehicle insurance — commercial cover for trucks and vehicles with specialist equipment
• Personal accident — essential given the high-risk nature of the work

Expect £1,000–£3,000+ per year for comprehensive cover.

Claimable Expenses

• Equipment — chainsaws, climbing equipment (ropes, harnesses, carabiners, saddles), chippers, stump grinders, hand tools
• PPE — helmets, visors, ear defenders, chainsaw trousers, chainsaw boots, gloves
• Vehicle costs — fuel, insurance, maintenance for trucks and chipper vehicles, or 45p per mile
• Equipment maintenance — chain sharpening, bar replacement, rope inspections, servicing
• Fuel for equipment — chainsaw fuel, chipper fuel
• Skip hire and waste disposal — or tipping fees for green waste
• Training and qualifications — NPTC renewals, climbing courses, first aid
• Professional memberships — Arboricultural Association
• Insurance premiums
• Marketing — website, van livery, local advertising
• Phone and communications
• Home office costs
• Subcontractor payments — if you bring in additional climbers or ground crew
• Accountancy fees

Accounted handles your expenses and matches receipts to bank transactions automatically.

Pricing

• Small tree felling — £200–£500
• Medium tree felling — £500–£1,500
• Large tree felling — £1,500–£5,000+
• Crown reduction — £300–£1,000
• Crown thinning — £200–£800
• Hedge trimming — £100–£300 per day
• Stump grinding — £50–£200 per stump
• Emergency tree work — premium pricing, often 50–100% above standard rates

Always conduct a site visit and provide a written quote. Factor in tree size, access, proximity to buildings, waste disposal, and any protected status.

Industry-Specific Considerations

Tree Preservation Orders (TPOs)

Trees may be protected by TPOs or be within a conservation area. Work on protected trees requires permission from the local planning authority. Carrying out unauthorised work on a protected tree is a criminal offence with unlimited fines.

Protected Species

Trees may contain protected species — bats, nesting birds. Work must comply with the Wildlife and Countryside Act 1981. Disturbing protected species carries significant penalties.

Waste Carrier Registration

You need a waste carrier licence from the Environment Agency to transport green waste. Registration costs around £154 for three years. Without it, you cannot legally transport waste from client sites.

Health and Safety

Tree surgery has one of the highest injury and fatality rates of any occupation. Strict compliance with health and safety regulations is both a legal requirement and essential for your business:

• Risk assessments for every job
• Method statements for complex work
• Proper PPE at all times
• Regular equipment inspections

Bookkeeping Tips

• Separate business and personal finances
• Track equipment purchases and maintenance
• Keep training and certification records
• Record waste disposal costs
• Set aside 25–30% of profits for tax
