Tradespeople work with tools, vehicles, materials, customer property, construction sites and members of the public. A single incident can involve injury, property damage, defective work, theft, delay and contractual disputes. Insurance should be selected around the trade, scale of work and responsibilities accepted.
This guide is for UK builders, electricians, plumbers, carpenters, decorators, roofers, landscapers and other manual trades. Specialist activities, hazardous work and regulated installations may need additional insurance and technical advice.
Quick answer
A trades business commonly considers:
- public liability insurance for injury or property damage to customers and others;
- employers’ liability insurance where employees or workers are within scope;
- tools, plant and equipment cover;
- contract works and materials cover for work in progress;
- motor insurance with the correct business use;
- professional indemnity where the trade designs, specifies, surveys or advises;
- product liability for goods made, altered, sold or supplied;
- business interruption, legal expenses and personal accident where relevant.
Start with the Business Insurance by Industry guide and describe every activity, including specialist and subcontracted work.
Public liability insurance
Public liability is a central consideration because tradespeople work in homes, businesses and public areas. Claims can allege injury, damage to buildings or belongings, escape of water, fire, falling objects, dust or other consequences of the work. The Public Liability Insurance guide explains common cover boundaries.
Check:
- the insured trade description;
- maximum depth, height or heat-work limits;
- work on roofs, scaffolds or underground services;
- use of subcontractors;
- damage to property being worked on;
- faulty workmanship exclusions;
- completed-work and product liability;
- pollution or contamination restrictions;
- excesses for water damage or heat work;
- client and principal-contractor limit requirements.
Public liability does not normally pay simply to redo defective work. It may respond to resulting injury or damage, subject to wording and exclusions.
Employers’ liability and labour arrangements
Most employers in Great Britain must have employers’ liability insurance, with a separate Northern Ireland regime. The Employers’ Liability Insurance guide explains legal requirements and status issues.
Trades businesses often use labour-only subcontractors, apprentices, casual workers, family members and self-employed specialists. The label used for payment does not by itself determine the insurance position. Disclose the workforce arrangement and record who controls the work, supplies tools and decides how tasks are carried out.
Health and safety remains separate
HSE guidance identifies small builders as a group facing serious risks, including falls from height. Insurance does not replace legal duties to plan, manage and monitor work, assess risks, use competent people and provide safe equipment and systems.
Maintain proportionate evidence such as:
- risk assessments and method statements;
- training and competence records;
- equipment inspections;
- permits for hot work where required;
- subcontractor checks;
- site inductions;
- incident and near-miss records;
- customer warnings and handover information.
Policy conditions may require particular controls, but compliance with a condition does not prove that all health-and-safety duties have been met.
Tools, plant and equipment
Tools can be insured on premises, in transit, at sites and in vehicles, depending on the policy. Check:
- total and single-item values;
- owned, hired-in and hired-out equipment;
- overnight vehicle cover and security conditions;
- unattended-site restrictions;
- theft evidence requirements;
- accidental damage and breakdown;
- replacement basis;
- continuing hire charges;
- geographical limits.
Keep an inventory with serial numbers, photographs and purchase evidence. The sum insured should reflect the policy valuation basis and current replacement cost where required.
Contract works and materials
Public liability does not automatically insure the value of unfinished work, materials or the contract itself. Contract works insurance may cover insured physical damage to work in progress and materials, subject to responsibility under the building contract.
Clarify:
- who is responsible for the works and materials;
- when risk passes to the customer;
- existing structures and property being worked on;
- temporary works;
- free-issue materials;
- off-site storage and transit;
- joint names or waiver requirements;
- testing and commissioning;
- defects and faulty-workmanship exclusions.
A domestic customer may assume the tradesperson’s policy covers everything, while the contract places responsibility elsewhere. Confirm the arrangement before work starts.
Vehicles and business use
Motor insurance is required for vehicles used on UK roads. The policy must also cover the correct business use, drivers and vehicle type. A private-car policy may not cover delivery of tools or travel between jobs.
Consider:
- vans and pickups;
- employee-owned vehicles used for work;
- trailers;
- carriage of goods or hazardous materials;
- tools left in vehicles;
- multiple drivers;
- hired vehicles;
- driving abroad.
Vehicle insurance and tools insurance are separate. Theft of tools from a van may be subject to different conditions and excesses.
Professional indemnity for design and advice
Tradespeople can have professional exposure where they design, specify, survey, calculate, certify or advise. HSE’s CDM guidance notes that a person can be a designer where they prepare or modify construction designs, and this can include specialist contractors or tradespeople actively involved in design.
Professional indemnity may therefore be relevant for:
- design-and-build responsibility;
- electrical or mechanical design;
- structural or load calculations;
- surveys and reports;
- specification of systems or materials;
- energy or compliance advice;
- certification beyond workmanship.
The Professional Indemnity Insurance guide explains why public liability is not a substitute for pure financial-loss cover.
Product liability and completed work
A trades business may manufacture, alter, install or supply products. Product liability may be included with public liability but can have separate definitions, limits and exclusions.
Tell the insurer about imported products, own-brand goods, safety-critical components, work incorporated into larger systems and products exported overseas. Keep supplier, batch and installation records to support traceability.
Customer contracts and main-contractor requirements
Review quotations, purchase orders, subcontract terms and framework agreements for:
- scope and specification;
- responsibility for design;
- insurance types and limits;
- indemnities and liability caps;
- damage to existing structures;
- delay and liquidated damages;
- retention of title and payment;
- defects and warranty periods;
- subcontracting permission;
- evidence and certificate requirements.
Do not accept a contractual limit or indemnity solely because the policy has the same headline limit. The policy may exclude contractual assumptions or particular work.
Cyber and payment fraud
Trades businesses increasingly use cloud accounting, job systems, online banking, smart devices and customer databases. Email compromise and false payment instructions can cause direct loss even where the physical work is unaffected.
Use multi-factor authentication, verify bank-detail changes independently, restrict administrator access, patch devices and maintain backups. The Cyber Insurance guide explains when incident-response or cybercrime sections may be relevant.
Choosing limits and excesses
Consider the largest site, customer property value, number of people exposed, potential escape of water or fire, contract requirements, product distribution and defence costs. A small job fee does not cap the damage that could follow an incident.
Check whether the public and product liability limits are each event, aggregate or subject to inner limits. Confirm the excess for property damage and specialist activities and ensure the business can fund it.
Cost factors
Premium may depend on trade, turnover, payroll, subcontractor payments, locations, claims, limits, tools values, heat work, height, depth, hazardous materials and contract type. The Business Insurance Costs guide explains how to compare quotations.
Accurate turnover and wage splits matter. Disclose specialist work rather than relying on a broad trade label that may exclude it.
Claims and incidents
After an incident:
- make the area safe and obtain emergency help where needed;
- follow legal reporting duties;
- notify the insurer or broker promptly;
- preserve photographs, quotations, risk records and correspondence;
- retain damaged items where safe;
- avoid admitting liability or agreeing repairs beyond urgent mitigation without advice;
- record subcontractors and witnesses.
The Public Liability Claim Scenarios guide illustrates how injury and property-damage allegations can develop.
Review triggers
Review cover when the business:
- hires employees or changes labour arrangements;
- adds roofing, hot work, excavation, design or another specialist activity;
- buys valuable tools, plant or vehicles;
- accepts larger commercial or public-sector contracts;
- begins importing or manufacturing products;
- works at greater heights or depths;
- changes premises or storage;
- enters a new territory;
- suffers an incident, complaint or theft.
Use the Business Insurance Review Checklist to record the change.
Next step
Prepare a trade activity schedule covering workforce, tools, vehicles, design duties, products, subcontracting and maximum project values. Compare it with the schedule, wording, endorsements and contract requirements before starting the next job.
Specialist and higher-risk activities
Many trade policies apply activity limits. Tell the insurer before undertaking work involving:
- roofing or work at significant height;
- excavation or work below specified depth;
- hot work, welding or cutting;
- asbestos or hazardous substances;
- structural alteration;
- demolition;
- work near railways, airports, docks or hazardous sites;
- security systems, alarms or safety-critical installations;
- gas, electrical or other regulated work;
- design responsibility;
- work outside the UK.
An activity can be excluded even when it is a normal part of the trade in everyday language. The endorsement and proposal answers control the insurance position.
Existing structures and property being worked on
Damage to the part of property being worked on can be restricted under public liability policies. Where a contractor works on a valuable existing structure, check whether the building owner’s insurance, contract works cover or a specialist extension is intended to respond.
Before work begins, record the existing condition with photographs and agree responsibility for fragile or valuable items. Confirm isolation of water, gas and electricity where relevant and keep evidence of permits and tests.
Hired-in plant and continuing charges
Hired equipment can create liability for repair, replacement and continuing hire charges after damage. Check the hire agreement and policy limit, including theft conditions, security, territorial scope and whether consequential charges are included.
The business should keep inspection, handover and return records. Damage caused by misuse or operation outside agreed conditions may be excluded or disputed.
Business continuity after a loss
A theft, vehicle accident, fire or injury can stop a small trade business. Plan for:
- replacement tools and vehicles;
- access to customer and job records;
- unfinished contracts and deposits;
- alternative suppliers and subcontractors;
- payroll and fixed costs;
- communication with customers;
- storage of materials;
- temporary premises;
- cash flow during an excess or waiting period.
Insurance sections may respond to different causes. A tools claim does not automatically pay lost profit, and business interruption may require insured damage at a specified location.
Scenario prompts
Escape of water damages several properties
Stop the leak, obtain emergency assistance, preserve evidence and notify the insurer. Review the property-damage excess, work-being-undertaken exclusion and any completed-work liability.
Tools are stolen from a van overnight
Report the theft and check whether security and overnight-location conditions were satisfied. Motor insurance does not normally replace the tools policy.
A labour-only subcontractor is injured
The business should have assessed the real working relationship and employers’ liability position before the incident. Notify the appropriate insurer and preserve site, induction and control records.
Installed work later causes damage
Product or completed-operations liability may be relevant, but the cost of replacing defective work itself can be treated differently from resulting damage. Check the wording and notify promptly.
A design decision is alleged to be wrong
Where the tradesperson selected or designed a system, professional indemnity may be relevant. Public liability alone may not cover pure financial loss or re-design costs.
Questions before tendering
Review:
- exact trade activities and exclusions;
- maximum contract value;
- public and employers’ liability limits;
- design responsibility;
- tools, plant and contract works values;
- principal-contractor insurance clauses;
- hot-work, height and depth conditions;
- subcontractor status and insurance;
- responsibility for existing structures;
- delay, warranty and indemnity clauses.
Price the insurance and risk-control implications into the job rather than accepting terms that the business cannot meet.
Certificates, evidence and principal-contractor checks
Commercial clients and principal contractors may request certificates before site access. Provide accurate evidence, but remember that a certificate does not amend the policy or prove that every activity is covered.
Check that the certificate shows the correct legal entity, period and limit. Keep copies of subcontractor certificates and verify them periodically where the contract requires this. Ask for the underlying scope or broker confirmation when the work is high risk; a headline limit alone does not show exclusions.
Quality, defects and customer complaints
A workmanship problem should be addressed through a documented process. Record the complaint, inspect the work, preserve photographs and agree any remedial access carefully. Consider notification before making an admission or undertaking extensive remedial work.
Insurance often distinguishes the cost of correcting defective work from resulting injury or damage. Customer service and warranty obligations therefore remain important even where liability insurance is held.
Weather, theft and site security
Outdoor and incomplete work can be exposed to rain, wind, frost, theft and vandalism. Plan temporary protection, secure materials and tools, and understand who carries the risk under the contract.
Policy conditions can specify fencing, storage, immobilisers, alarms or removal of tools from vehicles. The business should be able to show compliance. A failure to follow an important condition can affect a claim independently of whether the underlying theft or damage was foreseeable.
Records that support a claim
Keep:
- quotations and accepted scope;
- customer instructions and variations;
- pre-work condition photographs;
- risk assessments and permits;
- subcontractor and competence records;
- tool and plant inventories;
- receipts and hire agreements;
- installation, test and handover records;
- incident photographs and witness details;
- policy and notification correspondence.
These records help establish what happened, what work was included and which party was responsible.
Keep the declared trade current
Review the business description whenever new equipment, materials, techniques or contract roles are introduced. A broad trade name may not cover specialist work. Confirm changes in writing and retain the insurer or broker response with the schedule and endorsements.
