Insurance for Tradespeople: Everything You Need To Know

TL;DR

• Public liability insurance is not usually a legal requirement, but many customers, contractors and trade bodies expect it.
• Employers’ liability insurance is generally compulsory if you employ staff, including some apprentices and labourers. The legal minimum cover is £5 million.
• Tools, stock, vans, accidental damage, professional advice and unfinished work may all need separate or optional cover.
• Always describe every service you carry out accurately when arranging a policy. Working outside the declared trade can leave you uninsured.
• Price matters, but exclusions, excesses, policy limits and claims support matter more when something goes wrong.
• Keep qualifications, risk assessments, job records, photographs and certificates. They can help you defend or support a claim.
• As your work changes, update your insurer. This is particularly important if you move into gas, electrical, renewables, commercial work or subcontracting.

Why Tradespeople Need Insurance

Insurance is not about expecting the worst. It is about making sure one bad day does not put the business you have built at risk.

For a self-employed plumber, electrician, gas engineer, heating installer, roofer or general builder, a claim can arise from a simple accident. A ladder could damage a customer’s car. A leaking pipe could ruin a kitchen. A client could say that advice or design work caused them a financial loss. Your van and tools could be stolen overnight.

The detail matters because trades businesses are not all exposed to the same risks. An electrician working in occupied homes has different risks from a heating engineer installing boilers, or a contractor managing several people on a commercial site.

At Logic4training, we train both new entrants and experienced professionals across plumbing, gas, electrical, renewables, oil and F-gas. That gives us a close view of how careers develop: once you gain new skills and add new services, your insurance needs should develop too. Whether you are beginning with a new entrant trade course or expanding into heat pump training, review your policy before taking on the new work.

The Main Types of Trade Insurance

There is no single “tradesperson insurance” policy that automatically covers every risk. It is normally a package made up of liability cover and optional business protection.

Public Liability Insurance

Public liability insurance helps if your work causes injury to someone else or damage to their property. It can cover compensation and, depending on the policy, legal costs.

For example, a heating engineer fitting a radiator may accidentally damage a customer’s flooring. Or an electrician could leave a cable route unsafe and a visitor trips. A valid public liability policy may respond to these types of third-party claims, subject to its terms, exclusions and limits.

It is generally voluntary rather than compulsory, but it is often commercially essential. Local authorities, principal contractors, property managers and larger clients may ask to see proof of cover before you can start work. The Government’s business insurance guidance explains that public liability cover can protect against claims where a member of the public is injured or their property is damaged through business activities.

Common limits include £1 million, £2 million and £5 million. Higher limits may be required for commercial contracts, public-sector work or sites run by principal contractors. Do not choose a limit simply because it is the cheapest quote. Check the contract first.

Employers’ Liability Insurance

If you employ people, employers’ liability insurance is the cover to take especially seriously. In most cases, it is a legal requirement where people work for you under a contract of service or apprenticeship.

The Health and Safety Executive states that employers generally need at least £5 million of cover. It also notes that the minimum includes costs, and many insurers provide £10 million in practice. A business without suitable cover can face a fine of up to £2,500 for each day it is uninsured.

The word “employee” can be broader than many small businesses assume. It may include an apprentice, a labourer, a part-time worker or someone working under your direction. Status can be complicated where subcontractors are involved.

Do not rely on labels such as “self-employed subcontractor”. Ask your broker or insurer how it views the working arrangement, particularly if you control the person’s hours, methods, equipment or day-to-day work.

Tools, Plant and Equipment Cover

Tools are the engine of most trade businesses. If they disappear, work can stop immediately.

Tools cover may insure portable hand tools, power tools, test instruments, ladders and equipment against theft, loss or accidental damage. Some policies include tools left in a locked vehicle, but there may be strict conditions around security, parking hours, alarms and evidence of forced entry.

MoneyHelper’s guide to self-employed business insurance explains that business kit and machinery can be insured based on replacement cost or current value, and that tradespeople’s tools can sometimes be added to a liability policy.

Before buying, make an inventory. Record:

• The make, model and serial number of every significant item.
• Purchase dates and replacement values.
• Receipts, invoices and photographs.
• Where equipment is stored overnight.
• Any security devices fitted to your van or premises.

This is not just good administration. It gives you a much stronger starting point if you ever need to make a claim.

Professional Indemnity Insurance

Public liability is not the same as professional indemnity insurance.

Public liability is mainly about injury or physical property damage. Professional indemnity is designed for claims of financial loss caused by professional advice, designs, calculations, surveys, specifications or an alleged mistake in your work as an adviser.

This can matter for installers who design heating systems, specify electrical equipment, produce plans, advise on compliance or manage technical projects. It becomes more relevant when you move beyond straightforward installation into design-and-install work.

If you are progressing into low-temperature heating or heat pump work, make sure your policy reflects the exact services you provide. Logic4training’s low-temperature heating courses and heat pump training courses are aimed at installers working with these systems. New skills can create new opportunities, but your insurer must know about any change in scope.

Contract Works and Stock Cover

Contract works cover, sometimes called contractors’ all-risks cover, can protect work in progress, materials and temporary works if they are damaged before the job is handed over.

Imagine a partially fitted bathroom is damaged by a fire, flood or vandalism before completion. Or expensive materials are stolen from a site. Standard public liability insurance may not cover the cost of replacing your own work or materials.

This is particularly worth discussing if you:

• Work on larger building projects.
• Purchase materials before installation.
• Have responsibility for a site before practical completion.
• Work under a JCT, NEC or other formal contract.
• Store stock at a workshop, lock-up or home.

 

 

What Insurance Is Legally Required?

For most self-employed tradespeople working alone, public liability insurance is not a legal requirement. It is still strongly advisable because you can be personally responsible for injury or property-damage claims arising from your work.

The covers that are most likely to be legally required are:

• Employers’ liability insurance, where you employ people and do not fall within a specific exemption. The minimum legal cover is £5 million.
• Motor insurance, if you drive a vehicle on UK roads. Third-party cover is the legal minimum.

If you use a car or van for trade work, do not assume a domestic policy automatically covers you. Tell the insurer about business use, carrying tools and materials, multiple work locations and any employees who drive the vehicle. Your motor policy must reflect the actual use. Find further information in the Government’s vehicle insurance guidance.

Insurance premiums may be allowable business expenses for eligible self-employed people. GOV.UK lists business insurance, including public liability insurance, among expenses that can be claimed, subject to normal tax rules. Read the official guidance on self-employed legal and financial expenses. For tax advice specific to your circumstances, speak to an accountant or HMRC.

How Much Public Liability Cover Do You Need?

There is no universal figure. The correct level depends on what you do, where you work and what a claim could realistically cost.

A sole trader carrying out small domestic repairs may find £1 million or £2 million meets client expectations. An installer working in schools, commercial premises, communal areas or on major building sites may be asked for £5 million or £10 million.

Consider:

• The value of customers’ property you work in or around.
• Whether you work in occupied homes, public buildings or commercial premises.
• Whether a main contractor sets a minimum limit.
• Whether you employ staff or use labourers.
• The potential impact of fire, flooding, escape of water or electrical damage.
• Whether you carry out higher-risk work, such as hot works, work at height or excavation.
• Whether your policy covers the exact activity, not just the trade name.

A £5 million policy is not automatically better than a £2 million policy if it excludes the work you actually carry out. Scope of cover comes first.

Read the Policy, Not Just the Quote

Insurance can look similar until you need to claim. The important information is often in the schedule, policy wording and endorsements.

Check these points before you buy or renew.

1. Your Declared Trade Activities

Be precise. “Plumber” may not automatically include gas work, unvented cylinders, commercial heating, drainage, design work or renewable technologies. “Electrician” may not automatically include EV charging, solar PV, battery storage or inspection and testing.

Qualifications and competent training are essential, but they do not automatically change your insurance cover. If you are moving into a new area, such as gas, renewables or electrical work, tell the insurer before starting.

For anyone beginning in the sector, Logic4training’s career-change training routes explain how structured training and recognised qualifications can help build a proper route into plumbing, gas and electrical work. Insurance should sit alongside competence, not replace it.

2. Workmanship Exclusions

Many policies cover damage caused by defective work, but not the cost of redoing the defective work itself. The distinction is important.

For example, a policy may not pay to replace a poorly fitted valve. However, it might cover water damage to a customer’s kitchen caused by that valve failing, depending on the wording.

Ask the insurer to explain what is covered for:

• Defective workmanship.
• Defective materials.
• Rectification work.
• Consequential damage.
• Completed work after handover.

3. Excesses and Policy Limits

The excess is the amount you pay towards a claim. A low premium can come with a high excess, which may be difficult to absorb after a theft or accidental-damage incident.

Also check the difference between:

• The maximum paid for one claim.
• The total paid across the policy year.
• Separate limits for tools, stock, legal costs or hired-in plant.
• Limits that apply per item, per vehicle or while left unattended.

4. Subcontractors and Labour-Only Workers

Subcontracting is common in the trades, but insurance responsibilities are often misunderstood.

A bona fide subcontractor may have their own insurance. A labour-only subcontractor may be treated more like an employee for liability purposes. Your policy should clearly state whether it covers subcontracted work, and whether the subcontractor must carry their own public liability insurance.

Keep copies of subcontractors’ insurance certificates and check that their business description matches the job they are doing.

5. Height, Heat and Specialist Work

Work at height, hot works, excavation, asbestos exposure, work on listed buildings, commercial kitchens, high-value properties and offshore or overseas work can all trigger restrictions or special conditions.

Do not assume a standard package includes these activities. Declare them fully.

Conclusion

The right insurance will not prevent accidents, theft or disputes, but it can protect the business you have worked hard to build when they happen. Choose cover that reflects the work you do today, be honest about the services you plan to offer next, and review your policy whenever your business changes. Pairing suitable insurance with recognised training, up-to-date qualifications and safe working practices gives customers, contractors and you greater confidence in every job. Read more about training with us, or explore our full range of plumbing, gas, electrical and renewables courses if you are planning your next step.

FAQs

Is public liability insurance compulsory for tradespeople?

Usually, no. A sole trader is not generally legally required to hold public liability insurance. However, many customers, contractors and commercial sites require it before allowing work to start. It can also protect you if your work causes injury or property damage.

Do I need employers’ liability insurance if I use subcontractors?

Possibly. It depends on the real working relationship, not only what the subcontractor is called. If you direct their work and they effectively operate as part of your business, they may need to be covered. Speak to your insurer or broker and explain the arrangement clearly.

Does public liability insurance cover poor workmanship?

Often, it does not cover the cost of correcting defective work itself. It may cover accidental damage or injury caused by the defective work, depending on the wording. Always check the policy’s workmanship and exclusions clauses.

Are tools left in a van insured?

Not automatically. Tools cover may include theft from a locked vehicle, but policies can set security requirements, time limits and per-item caps. Check what counts as secure storage and make sure high-value tools are declared.

Do newly qualified tradespeople need insurance?

Yes, if they are working independently, taking on clients or operating a business. Qualifications demonstrate competence, but insurance protects against the financial consequences of accidents, claims and loss. Make sure the policy accurately reflects your trade and the work you are qualified and permitted to carry out.
