Sole Trader Insurance UK — What Cover You Need as a Tradesperson (2026)

Operating as a sole trader is the most common setup for self-employed tradespeople in the UK — and for good reason. It's simple to set up, cheap to run, and gives you full control over your income. But it comes with one significant exposure that limited company directors don't face: there is no corporate shield between your business and your personal finances.

If a customer sues you, or someone is injured because of your work, the claim doesn't stop at a company — it can reach your savings, your home, and everything else you own. The right insurance is what stands between a bad day on site and financial ruin. Here's everything you need to know.

Why insurance matters more when you're a sole trader

A limited company is a separate legal entity. A director can be personally liable in limited circumstances — fraud, negligence, wrongful trading — but in most cases the company absorbs the loss. As a sole trader, you are the business. Every liability the business incurs is personally yours. A £50,000 compensation claim against your work is a £50,000 claim against you. That's why getting your insurance right isn't optional admin — it's protecting your livelihood.

The seven types of cover UK tradespeople need

1. Public liability insurance (PLI)

Public liability is the most important policy for any tradesperson. It covers you if a third party — a customer, a member of the public, a neighbouring property — suffers injury or property damage as a result of your work. Crack a pipe that floods the flat below. Drop a tool that injures a bystander. Install wiring that causes a fire. PLI is what pays out.

Most main contractors won't let you on site without proof of PLI. The standard minimum is £2 million, but many commercial clients and larger contractors require £5 million. Domestic clients rarely ask, but you should carry it regardless — personal injury claims can be enormous. Typical cost for a sole trader is £100–£500 per year depending on your trade and turnover. Higher-risk trades (roofing, groundwork, structural) sit at the upper end; lower-risk trades (decorating, carpet fitting) at the lower end.

2. Employers' liability (EL)

If you employ anyone — even a part-time assistant, a temporary worker, or a labour-only subcontractor in certain arrangements — you are legally required to hold employers' liability insurance. The minimum cover is £5 million, and the fine for not holding it is £2,500 per day you operate without it.

The sticking point for many sole traders is subcontractors. If you hire someone on a labour-only basis — they use your tools and work under your direction — HMRC and your insurer may treat them as employees. Check with your broker before assuming you don't need EL. If in doubt, get it. The premium is typically small compared to the daily fine for non-compliance.

3. Professional indemnity (PI)

PI insurance covers claims that your professional advice, design, or specification caused a financial loss to a client. For most tradespeople who purely fit or install, it's less relevant. But if you specify materials, design heating systems, recommend electrical layouts, or give any technical recommendation that goes beyond pure labour — PI is worth considering.

A heating engineer who recommends an undersized boiler for a commercial property, or an electrician who designs an installation that later fails to comply with regulations, could face a PI claim for the cost of putting it right. Cover starts at around £200–£400/year for £250,000 of indemnity.

4. Tool insurance

Your tools are your income. If they're stolen from your van overnight, you can't work — and replacing a full kit can cost thousands. Tool insurance covers theft, loss, and accidental damage, typically up to £10,000–£15,000 per claim.

Read the small print carefully. The single most common reason claims are rejected is theft from an unattended vehicle. Most policies only pay out if the van was locked and there is evidence of forced entry. Leaving tools in an unlocked van, or a van with a broken lock you haven't reported, will usually void the claim. Some policies also exclude overnight storage — tools must be removed from the van or kept in a secure storage box bolted to the vehicle.

5. Van insurance

Your personal car insurance does not cover a van used for work. Even a standard van insurance policy may only cover social and domestic use. You need commercial vehicle insurance explicitly covering business use — driving between jobs, carrying tools, transporting materials.

If you carry other people's property in your van (materials bought on behalf of a client, for example) you may also need goods-in-transit cover. Check what your policy includes and what it excludes. Using a van for business without the correct cover is not just a civil risk — it can invalidate your insurance entirely and expose you to police action.

6. Personal accident and income protection

As a sole trader, there is no sick pay. If you fall off a ladder and break your wrist, your income stops immediately. Personal accident insurance pays lump sums for specific injuries — loss of a limb, loss of sight, permanent disability. Income protection insurance goes further: it pays a monthly income (typically 50–70% of your average earnings) for as long as you're unable to work, or until a set payment period expires.

This is the cover most tradespeople skip — and the one they most regret skipping when something goes wrong. Income protection premiums depend heavily on your age, health, and the deferral period (the longer you wait before payments kick in, the cheaper the premium). A basic policy can start at £30–£60 per month for a healthy sole trader in their 30s.

7. Contract works insurance

If you're working on a larger project — an extension, a new build, a major refurbishment — contract works insurance covers the work in progress if it's damaged before completion. A fire on a new build, a flood that destroys installed flooring, vandalism overnight on an exposed site. Without contract works cover, you may have to redo work at your own cost. This policy is often required by the main contractor on larger sites, and worth holding regardless on any project that would take more than a week to reconstruct.

Bundled policies and trade-specific insurers

Rather than buying each policy separately, most tradespeople are better served by a bundled tradesman policy. Insurers like Simply Business, Hiscox, AXA, and Tradesman Saver offer combined policies covering PLI, tools, and often van in a single annual premium. This simplifies your renewals, can be cheaper than buying separately, and means you're not juggling multiple certificates and renewal dates.

Compare policies carefully — bundled cover limits can be lower than standalone policies, and excess amounts vary significantly between providers. Use a broker if your situation is complex (multiple subcontractors, high-value tools, specialist work).

What invalidates a claim

Insurance policies contain conditions, and breaching them can mean a valid claim gets rejected. The most common reasons trade claims fail:

• Working outside your stated trade. If your policy covers 'plumbing' and you're doing structural groundwork when an incident occurs, you may not be covered. Declare your full scope of work accurately when buying a policy.
• No forced entry evidence for tool theft. As above — locked van, signs of break-in, police report number. Without these, most claims fail.
• Operating without the correct certifications. If you're Gas Safe registered and your registration lapses, or you carry out notifiable electrical work without NICEIC or NAPIT registration, your insurer may argue you were operating outside your competency. Keep every certification current.
• Non-disclosure. Failing to disclose previous claims, convictions, or health conditions when buying a policy can void the entire contract.

How much cover do you actually need?

Start with what your clients and contractors require. Before signing any commercial contract, check the insurance clause — many specify minimum PLI limits, and some require you to name the client as an additional insured. If you're predominantly domestic, £2m PLI is generally sufficient. If you're working commercial contracts or on large residential sites alongside other trades, £5m is safer.

Don't assume domestic work is lower risk than commercial. A flooded house or a fire caused by your work can easily exceed £2m when you factor in hotel accommodation, temporary repairs, contents damage, and loss of rental income. Match your cover to the worst realistic outcome of your work, not the average job.

Keeping your certificates current

PLI and EL certificates typically renew annually. Some clients — particularly letting agents and commercial property managers — will check your certificate before every job, not just the first time you work for them. Keep a digital copy of every certificate on your phone and in your CRM or job management system. If you're using Trade2Base, you can store certificates against your profile and share them directly when a client requests proof of cover.

Set a reminder 30 days before each policy renewal so you have time to compare quotes rather than auto-renewing with the same provider. Premiums can change significantly year on year, and switching providers is straightforward if your claims history is clean.

Are insurance premiums tax-deductible?

Yes — in full. All business insurance premiums are an allowable business expense under HMRC rules. That means you deduct them from your trading profit before calculating Income Tax and National Insurance. If you're a basic-rate taxpayer, every £100 in premiums costs you £80 after tax relief. If you're higher-rate, it costs £60. Keep your invoices and proof of payment in your records for at least five years.

The only exception is insurance that covers a personal risk rather than a business one — so a critical illness policy or a mortgage protection policy would not be deductible, even if you're self-employed. Income protection sits in a grey area: if the policy pays out directly to you rather than the business, HMRC typically treats premiums as non-deductible. Check with your accountant.
