Tree surgery is skilled, physical and well paid. Homeowners need crown reductions and felling, councils and estates need surveys and maintenance, developers need site clearance and every big storm brings emergency work. Qualified, insured tree surgeons who turn up and do a clean job are in steady demand.
It is also one of the most dangerous trades in the UK. Chainsaws, climbing, falling timber and chippers leave little room for error. The tree surgery businesses that last combine safety discipline with sound pricing, equipment control and cash flow. This guide explains how to start a tree surgery business in the UK.
1. Choose your services
- Crown reductions, lifts and thinning: the core of domestic work.
- Felling and sectional dismantling: higher risk and higher value.
- Stump grinding: quick, profitable add-on with the right machine.
- Hedge cutting: steady, seasonal, lower skill.
- Tree surveys and reports: for planning, mortgages and estates. Needs arboricultural knowledge.
- Storm damage and emergency work: premium rates, unsocial hours.
- Site clearance: for developers and landowners. Big jobs, big waste volumes.
Most firms start with domestic work, add stump grinding and hedging, and build towards commercial contracts.
2. Qualifications
Chainsaw work is regulated by health and safety law: anyone using a chainsaw at work must be competent, and in practice that means recognised chainsaw qualifications (such as NPTC or Lantra certificates) for maintenance, cross-cutting, felling, climbing and aerial rescue. Insurers and commercial clients will ask for them. Climbers need aerial rescue training, and someone on the ground must be able to perform a rescue.
Log every operator's qualifications and refresher dates in your compliance register.
3. Business structure and insurance
Most tree surgeons start as sole traders and move to a limited company as they grow. Open a business account from day one.
Insurance matters more than in most trades:
- Public liability insurance: essential. A falling limb on a car, conservatory or person can mean an enormous claim. Check that tree work, height limits and felling are covered.
- Employers' liability insurance: a legal requirement once you employ anyone.
- Tools and plant insurance: chippers, stump grinders and saws are valuable and stolen often.
- Vehicle insurance for your truck and trailer.
Trade association membership, such as an approved contractor scheme, is a strong trust signal for homeowners and councils.
4. Protected trees and wildlife
Before cutting, check whether a tree is protected. Trees covered by a tree preservation order (TPO) or in a conservation area usually need council consent or notice before work. Nesting birds are protected by law, so check for active nests before cutting, especially in spring and summer. Build these checks into your quoting process and keep records.
5. LOLER and equipment inspections
Climbing and rigging equipment used for lifting people or loads falls under the Lifting Operations and Lifting Equipment Regulations (LOLER). Equipment used to lift people, such as climbing gear, needs a thorough examination by a competent person at least every six months, plus pre-use checks every day. Keep records of every inspection.
Daily equipment checks should include:
- Chainsaws: chain brake, chain catcher, throttle lock and sharpness
- Climbing ropes and harnesses inspected before use
- Wood chipper safety bar and feed checked
- Drop zone and work area coned off
- Aerial rescue plan in place for every climb
Weekly: trailer and load checks, PPE (chainsaw trousers, boots, helmet, eye and ear protection) and equipment cleaning.
6. Tree surgery risk assessment
Your tree surgery risk assessment should cover:
- Working at height: climbing, MEWPs and rigging.
- Chainsaw cuts: trained operators, full chainsaw PPE, chain brake checks and never working alone.
- Falling branches and timber: drop zones, helmets, rigging plans and a banksman.
- Chippers and stump grinders.
- Overhead power lines: survey every site. Work near lines may need the network operator involved.
- Members of the public: cordons and signage.
- Manual handling of timber and brash.
Write a site-specific assessment for every job, and a general one for your business.
7. Tree surgery prices
Tree surgery prices vary hugely with tree size, access, location, risk and waste. Most firms quote per job, built from:
- Crew hours × your charge per crew hour
- Crew cost per hour (wages for the climber and groundworkers)
- Disposal and hire: green waste disposal, chipper or MEWP hire, traffic management
- Overheads and profit
Track revenue per crew hour across jobs. Access problems, heavy waste and travel can turn an attractive quote into a poor hourly return. A pricing calculator that works back from your target margin helps you quote consistently.
8. Waste
Tree work produces a lot of waste: chip, logs and brash. Register as a waste carrier if you transport it, and know where it goes. Selling logs and using chip as mulch can turn a cost into income. Track disposal costs per job, because they can quietly eat your margin.
9. Job tracking and repeat work
For each job record customer and site, work type, crew hours, charge per crew hour, crew cost per hour, disposal and hire costs, revenue, total cost and gross profit, job date and next inspection or re-cut due. Hedges need cutting every year, crowns need reducing every few years and survey clients need reinspection. Reminders turn one-off jobs into repeat income.
10. Stock and consumables
Track chain oil, two-stroke fuel, saw chains, chain files, rigging rope, felling wedges, stump grinder teeth and gloves with unit cost, opening stock, deliveries, closing count and reorder level. Running out of chain oil or teeth mid-job wastes a crew day.
11. Invoices, VAT and cash flow
Invoice on completion and track every invoice as Paid, Open or Overdue, with an aged debtors report for commercial clients. Register for VAT once taxable turnover passes the HMRC threshold, and keep a quarterly VAT summary.
Tree surgery is seasonal and equipment-heavy. A 12-week cash flow forecast shows money in, money out for wages, fuel, finance on chippers and grinders, disposal and tax, with warnings for weeks the balance goes negative.
Common mistakes new tree surgeons make
Underpricing waste. Disposal can be a big cost on large jobs. Price it in every quote.
Skipping protected tree checks. Working on a protected tree without consent can mean fines and reputational damage.
Letting inspections lapse. LOLER records and chainsaw servicing are easy to forget when busy, and essential if anything goes wrong.
Working short-handed. Chainsaw work alone and climbing without a trained rescuer on the ground are serious risks.
The numbers to check every month
Review average job value, crew hours sold, revenue per crew hour, disposal and hire as a percentage of revenue, overdue invoices and your lowest cash balance over the next 12 weeks.
How to market your tree surgery business
Photos of clean finished jobs, genuine reviews and clear proof of qualifications and insurance win domestic work. Approved contractor status and relationships with councils, estates, letting agents, builders and landscapers bring steady commercial work. Respond fast after storms. Track where each enquiry comes from.
Your first 90 days as a tree surgeon
Month one: get qualifications, insurance, waste carrier registration and inspection records in place before taking paid work. Start with hedging, small reductions and stump grinding to build cash and reviews. Month two: track crew hours and disposal costs on every job and compare with your quotes. Month three: use your figures to set a minimum job price and a realistic charge per crew hour, then start approaching letting agents, estates and landscapers for regular work.
Buying equipment: hire first, buy later
Chippers, stump grinders and MEWPs are expensive. Hire them per job until your job tracker shows you are using them often enough to justify finance. Track hire costs as a percentage of revenue: when they climb, it may be time to buy. Factor finance payments into your cash flow forecast before you sign.
How to work out your break-even
Break-even is the number of crew hours you need each month to cover all your costs. It is the single most useful number for a new tree surgery business.
1. Add up your monthly fixed costs: everything you pay whether you are busy or not, such as rent, insurance, vehicle finance, phone, software, marketing and your own minimum drawings. 2. Work out your contribution per crew hour: your price per crew hour minus the variable cost of delivering it (staff time, materials, fuel, products or fees). 3. Divide fixed costs by contribution.
For example, if your fixed costs were £3,000 a month, your average price per crew hour was £55 and your variable cost per crew hour was £30, each crew hour would contribute £25 towards fixed costs. You would need about 120 crew hours a month just to break even. Everything above that is profit. These figures are illustrations only: use your own.
Knowing your break-even tells you how busy you need to be, whether a quiet month is a problem, and what happens if you raise prices or cut costs. A price rise lowers your break-even straight away, which is why pricing is usually the fastest lever you have.
When and how to raise your prices
Costs rise every year: fuel, insurance, materials, wages and rent. If your prices stay still, your margin shrinks. Review prices at least once a year, and sooner if a major cost jumps.
Signs you are undercharging:
- You are fully booked weeks ahead
- Customers rarely question your price
- Your gross margin is falling month by month
- You are busy but your bank balance is not growing
Raise your minimum job price and charge per crew hour on new quotes first, and price disposal separately so customers see what they pay for. Track your average price and gross margin monthly after any change, so you can see the effect in your own numbers rather than guessing.

Frequently asked questions
How much does it cost to start a tree surgery business? The main costs are training, chainsaws, climbing kit, a vehicle and trailer, insurance and, later, a chipper and stump grinder. Hiring larger machines at first keeps start-up costs down.
Do tree surgeons need qualifications? Anyone using a chainsaw at work must be competent, and recognised chainsaw and climbing certificates are the standard way to show that. Insurers and clients will expect them.
How often does climbing equipment need inspecting? Equipment used to lift people should have a thorough examination at least every six months, plus checks before every use.
Do I need permission to cut down a tree? If a tree has a preservation order or is in a conservation area, you usually need council consent or must give notice. Always check first.
What software do tree surgeons use? Many small firms use a spreadsheet for job costing, crew hours, waste, invoices, inspections and cash flow before moving to paid software.
