Trade business insurance UK: complete guide (2026)

Insurance is one of those costs that feels like money wasted until the day you need it — and when that day comes, the right cover is the difference between absorbing a setback and losing your business. This guide covers every type of insurance a UK tradesperson should consider: what each policy covers, how much you should expect to pay, and how to buy it without overpaying.

Why insurance matters for tradespeople

The consequences of being uninsured as a tradesperson are not abstract. A burst pipe caused by a careless fix can flood a home and cost tens of thousands in remediation. A customer tripping over your tools can result in a personal injury claim that runs well into six figures with legal costs. A van break-in that takes your tools means you cannot work until you replace them — often at a cost of £5,000–£15,000 for a fully kitted trade van.

For employed tradespeople, these risks are largely covered by their employer. For sole traders and directors of small limited companies, the full exposure sits with the business — and if the business cannot pay, it often sits with you personally. Proper insurance is therefore not a luxury but a structural requirement of operating a professional trade business.

Beyond protecting you, insurance signals professionalism to customers. Many commercial clients, housing associations, and local authorities require proof of public liability insurance before letting any contractor on site. Not having it shuts you out of entire categories of work.

Public liability insurance

Public liability (PL) insurance covers you if your work injures a member of the public or damages their property. It is the single most important policy for any tradesperson who works in or around customers' homes or commercial premises. If a customer slips on a wet floor you have just mopped, or your drilling damages a hidden pipe, PL covers the resulting claim — legal defence costs, compensation, and any remediation costs up to your policy limit.

Common PL claims in the trades include accidental property damage (by far the most frequent), personal injury to a homeowner or their visitor, and defective workmanship causing consequential loss (for example, incorrect pipe installation causing long-term water damage).

Cover levels are typically available at £1 million, £2 million, and £5 million. For most sole traders doing domestic work, £1 million to £2 million is sufficient. If you are tendering for commercial contracts, housing association work, or any public sector jobs, you will almost certainly be required to carry at least £5 million cover — check the tender specification before applying.

Employers' liability insurance

Employers' liability (EL) insurance is a legal requirement in the UK if you have employees. Under the Employers' Liability (Compulsory Insurance) Act 1969, you must hold at least £5 million of EL cover — though in practice most policies provide £10 million as standard. Failure to hold EL when required can result in a fine of up to £2,500 per day.

The definition of “employee” for EL purposes is broader than many tradespeople expect. Casual labour, apprentices, labour-only subcontractors who work exclusively for your business, and even volunteers can all be considered employees under the Act. If you pay someone to work for you on a regular basis — even cash in hand — you may legally need EL cover for them.

EL insurance covers you if an employee is injured at work or develops a work-related illness and makes a claim against you. In the construction and trades industries, claims for hand-arm vibration syndrome (HAVS), noise-induced hearing loss, back injuries, and fall injuries are all common.

Tools and equipment cover

Tools cover pays out if your tools are stolen, lost, or damaged. Given that a professional tradesperson's toolkit can easily be worth £5,000–£20,000 — more for specialist trades like electricians with test equipment or plumbers with pipe equipment — the cost of replacing a full set of tools out of pocket can be devastating.

When buying tools cover, pay close attention to two things. First, whether the policy is “new-for-old” (replaces tools at current retail value) or “indemnity basis” (pays the depreciated value — which for a 5-year-old drill may be almost nothing). New-for-old is significantly preferable. Second, check the per-item limit and the total policy limit. Some policies cap individual items at £500 and the total claim at £3,000 — which may fall well short if you have high-value power tools.

Also check where your tools are covered. Many standard home insurance policies exclude tools in an unattended vehicle overnight — which is exactly where tradespeople store them. A specialist trade tools policy will typically cover your van as a storage location, with conditions around security (locked van, slam locks, Thatcham-rated alarm).

Van and fleet insurance

Your van insurance must include business use. Standard “social, domestic and pleasure” cover is designed for private cars used for personal journeys — it does not cover driving to customers' properties, carrying tools and materials for work, or operating as part of a trade business. If you have an accident while working and your policy only covers personal use, your insurer will decline the claim.

For vans used for trade purposes, you need “business use” cover as a minimum, or a specific commercial van insurance policy. If you have employees driving the van, they must be added as named drivers or the policy must include “any driver” cover. For multiple vehicles, a fleet policy often works out cheaper than individual van policies and simplifies renewal significantly.

The cost of van insurance for a tradesperson varies significantly based on the driver's age, claims history, the vehicle's value and engine size, and the area where it is kept overnight. Adding security features (Thatcham-approved alarm, deadlocks, tracking device) typically reduces premiums meaningfully.

Professional indemnity insurance

Professional indemnity (PI) insurance covers you if a client suffers a financial loss due to your professional advice or designs being wrong or misleading. For most tradespeople doing purely installation or repair work, PI is not required. However, it becomes relevant if you are providing design or specification services — for example, a design-and-build bathroom or kitchen contractor, a structural engineer or surveyor, or a contractor specifying materials or systems as part of a contract.

If a client follows your specification and later discovers it was incorrect — say, a drainage design that floods, or a structural calculation that turns out to be wrong — PI covers the resulting claim. Some construction clients and frameworks require PI cover from all contractors, so check tender requirements carefully.

How to buy trade insurance

There are three main routes to buying trade insurance. Comparison sites (such as Simply Business, PolicyBee, or Go Compare for trade insurance) let you see multiple quotes side by side and are good for straightforward sole trader policies. Specialist trade brokers — such as those specialising in construction, electrical, or gas — can often get better rates for more complex risks or where the insured trades are higher-risk. Trade body schemes are worth checking if you are a member of organisations like the NICEIC, Gas Safe, APHC, or the FMB — many offer discounted group insurance schemes as a membership benefit.

When comparing policies, do not just compare price. Look at the excess (the amount you pay on each claim), what is and is not covered, whether cover is claims-made (must be active when the claim is made) or occurrence-based (must be active when the incident happened), and the insurer's financial strength rating.

What affects your premium

Insurers price trade policies based on several factors: your trade type (roofers and scaffolders pay more than painters), your annual turnover, the number of employees, your claims history, the geographical area where you work, and the cover levels you select. Some trades — particularly those working at height, with gas, or with high-value materials — will always attract higher premiums than lower-risk trades like decorating or garden maintenance.

You can often reduce premiums by: paying annually rather than monthly (typically 10–15% saving), increasing your excess, keeping a clean claims record, demonstrating professional qualifications and trade body membership, and bundling multiple covers (PL, tools, van) into a single combined trade policy.

Trade2Base and insurance: using job records as evidence

If you ever need to make an insurance claim — or defend against one — your ability to produce accurate records of the work you carried out, when you carried it out, and what was agreed with the customer can be the difference between a successful claim and a disputed one. Insurers and solicitors both look for contemporaneous documentation: records created at the time of the job, not reconstructed later.

Trade2Base automatically timestamps every job record, quote, and invoice, and stores customer communications against the job. Photos attached to jobs are stored with metadata. If a customer disputes your workmanship or a third party makes a claim, your complete job record — signed quote, job notes, photos before and after, invoice — is available immediately and is legally robust.

You can also store your insurance certificates and policy details in Trade2Base and set annual renewal reminders, so you never accidentally let a policy lapse or send a customer a certificate for a policy that has expired.
