Arborist Business Insurance Guide UK 2026

What Insurance Does a Tree Surgeon Need?

In short: two covers are legal requirements: employer's liability once you employ anyone (with a few exceptions), with at least £5M of cover, and motor insurance for any vehicle used on the road. Public liability isn't a legal requirement, but councils, estates and commercial clients often ask to see the certificate. The limit each client asks for varies with the work, so check the contract. Plant and equipment cover is strongly advised, income protection is advised for sole traders, and professional indemnity is for anyone who writes tree reports.

Why Insurance Is Non-Negotiable in Arboriculture

Tree surgery is high-risk work: working at height with chainsaws, next to buildings and roads, and with heavy machinery. A single incident, such as a falling branch damaging a neighbour's conservatory or an employee injured on site, can lead to claims well into six figures.

Beyond the financial risk, insurance opens doors. Councils, estates and commercial clients often ask to see your public liability certificate before you start, and some set a minimum amount of cover. Without it, you can't bid for that work.

This guide explains the policies every arborist business should hold, what they cover, and what to watch out for when comparing policies. It applies whether you are a sole trader with one van or a company with six climbers.

The Core Policies Every Arborist Business Needs

1. Public Liability Insurance (PLI)

What it covers: Injury to a third party or damage to their property arising from your business activities.

Typical example: A branch section falls beyond the exclusion zone during a crown reduction and damages a parked vehicle or injures a bystander. PLI covers the claim, legal costs, and any award.

Limits: each client sets the limit it asks for, and it varies with the work. Check what your contracts ask for, and get a quote at the next level up too, so you can see the difference.

Premiums increase with turnover, team size, and the type of work carried out. Aerial and rigging operations attract higher loadings than ground-based work.

2. Employer's Liability Insurance (ELI)

What it covers: Injury or illness suffered by your employees arising in the course of their employment.

Legal status: Compulsory for most employers. In England, Scotland and Wales, the Employers' Liability (Compulsory Insurance) Act 1969 requires most businesses with employees to hold ELI, with cover of at least £5M (1998 Regulations, reg 3). Exemptions include a family business that isn't a limited company where all the employees are close relatives, and a company whose only employee is its owner holding 50% or more of the shares (HSE). Not having it is a criminal offence: HSE enforces the law, and you can be fined up to £2,500 for every day you're without suitable insurance (HSE). Northern Ireland has its own equivalent law (the 1972 Order). You must also display the certificate where your staff can see it, for example at work or on your website, and show it to inspectors if they ask. If you don't, you could be fined £1,000 (GOV.UK).

Who counts as an employee: Full-time, part-time, seasonal, casual, and labour-only subcontractors can all meet the legal definition of "employee" for ELI purposes depending on how they are engaged. If someone is on your payroll or under your direction and control, assume ELI applies and verify with your broker.

Sole traders with no employees: ELI is not legally required. However, if you take on even a day's casual help, you will probably need it: what counts is how much you control their work, not what you call them (HSE). Buy it before that day, not after.

3. Plant, Machinery and Equipment Insurance

What it covers: Physical damage to and theft of your plant (chippers, stump grinders, mini diggers, tractors), hand tools, and vehicle-carried equipment.

Why arborists need it separately from PLI: PLI covers damage you cause to other people's property. It does not cover your own equipment. Without plant and machinery cover, a stolen chipper or a written-off stump grinder is an uninsured loss.

Elements to insure:

Plant and machinery (chipper, stump grinder, tracked loader, brush cutter)
Climbing and rigging equipment (ropes, harnesses, helmets, blocks — note LOLER inspection does not substitute for insurance)
Power tools (chainsaws, pole saws, hedge cutters — high theft risk)
Trailers

Key policy terms to check:

Unattended cover: most policies exclude theft from an unattended vehicle overnight unless stored in a locked, alarmed building. Leaving a chipper on site overnight is a common exclusion trigger.
Tools in transit: check whether tools in a van are covered or require a separate tools-in-transit extension.
Agreed value vs market value: agreed value pays out the insured sum; market value pays out depreciated cost. For key machinery, negotiate agreed value.

Premiums depend on the machinery's age and value and where you store it.

4. Commercial Motor and Fleet Insurance

What it covers: Your vans, trucks, tippers, and any other business-registered vehicles.

Arborist vehicles fall into two categories with different insurance implications:

Light commercial (van, pick-up or tipper up to 3.5t GVW): Standard commercial motor policy. Ensure the policy explicitly covers carriage of tools and machinery and specifies all drivers (including any employees who drive the vehicle).

Heavy commercial (tipper or crew-cab lorry over 3.5t, 7.5t truck): Usually needs a specialist HGV policy. For operator licensing, a heavy goods vehicle is a goods vehicle, or a vehicle combination including one, with a maximum laden weight over 3.5 tonnes (Goods Vehicles (Licensing of Operators) Act 1995 s.58), so a 3.5t tipper on its own isn't one. But a 3.5t vehicle towing a trailer over 1,020kg unladen falls outside the small-goods-vehicle exemption, so in Great Britain it needs an operator's licence (Northern Ireland has its own rules: GOV.UK) (GVOLA 1995 Sch 1, paras 2–3); see our startup costs guide. If you operate a grab lorry, confirm that the crane/grab arm is covered as fitted equipment.

What commercial motor does NOT cover:

Injury to your own employees while they're working (that's for your ELI), except when they're being carried in or on the vehicle, or getting into, onto or out of it (see Road Traffic Act 1988 s.145)
Goods in transit if you are carrying clients' timber or equipment
Towed plant — trailers require either a separate trailer policy or an explicit trailer extension on your motor policy

Tipper bodies and chipper attachments: Check with your broker whether permanently fitted equipment (a tipper body, a roof rack with equipment) is insured under the vehicle or separately. There is often a gap.

Additional Policies Worth Considering

5. Personal Accident and Income Protection

What it covers: Loss of income if you are unable to work due to accident or illness.

For sole traders, this is often the biggest gap. Self-employed people can't get Statutory Sick Pay. You may be able to claim New Style ESA or Universal Credit, but they won't replace your income. If you cannot work for three months after a chainsaw injury or a climbing fall, your income stops.

Personal accident: pays a lump sum or weekly benefit for specified injuries; typically cheaper but narrower cover
Income protection insurance: pays part of your income each month after a waiting period you choose; more comprehensive but higher premium
Critical illness cover: lump sum on diagnosis of specified serious conditions; relevant if your capital (van, equipment) relies on your continued health to service any borrowing

6. Professional Indemnity Insurance (PII)

What it covers: Claims arising from professional advice or reports you issue — arboricultural surveys, TPO application support, tree condition reports, planning authority submissions.

Who needs it: If your work involves tree reports (pre-development surveys, tree surveys for planning, condition assessments for BS5837 compliance), professional indemnity is relevant. If you solely carry out physical works (felling, pruning, planting) and issue no advisory reports, PII may not be required — check with your broker.

Local authorities and developers may ask for PII as well as PLI for survey or report work. PII is usually written on a "claims made" basis: it must be in force when the claim is made, not just when you did the work. Keep cover going, or buy run-off cover, for at least 6 years after your last report: in England and Wales most claims can be brought for 6 years (Limitation Act 1980), and some negligence claims later.

What Your Insurance Should Exclude (And What to Watch)

Common exclusions in arborist policies

Height exclusions: Some general tradesman policies exclude work above a set height (for example 6m). Specialist arborist policies usually cover aerial work, but check the wording before you buy.

Pollution exclusions: Chemical treatment (treating stumps with herbicide, or other pesticide use) may require a pollution liability extension. Check whether your PLI covers gradual pollution events (e.g., herbicide runoff into a watercourse) or only sudden events.

Contractual liability: Many PLI policies exclude liability assumed under contract (e.g., an indemnity clause in a commercial client's works agreement). Commercial clients sometimes attempt to insert broad indemnities — check what your policy will and will not back.

Felling licence and TPO compliance: A claim arising from an unlicensed felling or a TPO breach may be excluded on public policy grounds. Ensure you have verified legal authority to fell before commencing work.

Buying Arborist Insurance: What to Look For

Use a specialist broker

General commercial insurance brokers often have limited experience pricing arborist policies and may default to exclusions that make the policy unfit for purpose (height limits, aerial work exclusions, chainsaw exclusions). Specialist brokers who work with the arborist and forestry sector understand the risk profile and can write cleaner cover.

Ask any broker you approach:

Does this policy cover aerial tree surgery without height limit?
Does it cover chainsaw use as a hand tool?
Is there a pollution liability extension?
How is ELI structured if I use day labour?
What is the unattended plant and equipment exclusion?

Get at least three quotes

Prices for the same cover can vary a lot between insurers, so get at least three quotes.

Check the insurer's claims handling reputation

A policy is only as good as its claims service. Before you buy, read reviews of the insurer itself, not just the broker, and ask other tree surgeons how their claims went.

Insurance and Equipment Sales

When you buy or sell equipment — particularly plant, chippers, and climbing gear — insurance has practical implications:

Buying used equipment: Ensure any purchased plant is insured from the moment you take ownership. There is no automatic extension of the seller's policy. See our guide to PUWER compliance for arborist equipment for maintenance records you should receive at purchase — these also inform insurers of the equipment's condition history.

Selling used equipment: Remove the item from your plant and machinery schedule when it transfers to the buyer. Continuing to pay premium on sold equipment is a waste; failing to inform your insurer of a material change can complicate future claims.

Whoever you buy from, ask for the maintenance history — clean maintenance records support smoother insurance applications for specialist plant.

Start-Up Insurance Considerations

If you are setting up an arborist business, insurance is a day-one requirement — not something to arrange once you have clients. See our guide to tree surgery startup costs UK 2026 for a full breakdown of first-year capital requirements, including insurance as a fixed overhead.

For new businesses:

Expect higher premiums with no claims history
Prices often come down once you have a few years without claims
Keep thorough records of every job (RAMS, completion photos) — these support your claims record

Renewals and Policy Reviews

Review your insurance every year at renewal, not just renew it. Your policy says which changes you must tell your insurer about. They usually include:

Adding employees or subcontractors to the payroll
Buying significant new plant or equipment
Starting new types of work (aerial operations if you previously did ground work only)
Significant turnover increase or decrease
Moving your equipment storage location
Any circumstances that might give rise to a claim (even if a claim has not been made)

If you don't tell your insurer something you should have, it can pay less on a claim, or in serious cases refuse it (Insurance Act 2015). That's the most expensive moment to find the gap.
