Can You Be Liable for a Self-Employed Substitute, Helper or Subcontractor?
Can You Be Liable for a Self-Employed Substitute, Helper or Subcontractor?
This article is part of our self-employed injury risk series.
In earlier articles, we looked at different ways responsibility can arise when a self-employed person is involved in an accident at work.
First, we looked at whether the person is genuinely self-employed, or whether they have only been labelled that way. If the work is controlled, directed and organised by another business, the relationship may be closer to employment or “akin to employment”. In that situation, responsibility may not sit with the self-employed person alone.
Second, we looked at what happens if the person is genuinely self-employed. In that situation, responsibility may switch back to the self-employed person. They may need to think not only about their own injury, but also whether someone else could be injured because of their work, tools, method or mistake.
Third, we looked at common calling and undertaking. If you are genuinely self-employed and hired for your skill, you may be expected to understand and manage ordinary risks connected with your own trade or the work you agreed to undertake.
Fourth, we looked at client premises. Even if you are genuinely self-employed, you may still be injured because of unsafe premises, hidden hazards, inadequate warning or poor site management.
Can You Be Liable for a Self-Employed Substitute, Helper or Subcontractor?
This article looks at another important situation:
What happens if you are self-employed, but you bring in another self-employed person, substitute, helper or subcontractor?
That can create a new risk.
If that person injures someone, damages property, or creates a danger while carrying out work for you, the question may become: Could responsibility come back to you?
Why this matters for self-employed people
Many self-employed people do not work completely alone.
You may sometimes:
send a substitute;
use a helper;
bring another tradesperson onto a job;
ask another self-employed person to cover work;
subcontract part of a job;
use a driver, labourer, assistant or installer;
rely on another person to complete work you agreed to do.
This can be practical and normal.
But it can also create legal and insurance risk.
If that person causes injury or damage, the client, injured person, insurer or another business may ask who was really responsible for the work.
Was the other person running their own independent business?
Or were they carrying out your work, under your control, for your benefit, as part of the service you agreed to provide?
That distinction can matter.
The self-employed label may not be enough
Calling someone self-employed does not automatically answer the question.
You may describe the person as a subcontractor, substitute or independent contractor.
They may invoice you.
They may use their own vehicle or tools.
They may not be on payroll.
But if you control what they do, how they do it, where they go, what system they follow, and how the work is presented to the client, the practical relationship may need closer checking.
The issue is not only the label.
The issue is how the arrangement works in practice.
Vicarious liability: when one person may be liable for another
Vicarious liability is a legal concept where one person or business may be made responsible for the wrongful act of another person.
It most commonly arises where an employer is liable for the acts of an employee carried out in the course of employment.
But the law may also look at relationships that are not formal employment, but are close to employment or “akin to employment”.
That is why a self-employed business owner should be careful when using substitutes, helpers or other self-employed people.
If the work is being carried out for you, under your arrangements, for your benefit, and as part of your service to the client, someone may argue that responsibility should point back to you.
The two practical questions
In this situation, there are usually two practical questions.
First:
Was the person genuinely independent?
Second:
Was the injury or damage connected with the work they were authorised to do for you?
Both questions matter.
If the person was genuinely running their own separate business, using their own method, taking their own risk, and simply providing an independent service to you, responsibility may sit with them.
But if they were effectively working under your direction, carrying out your job, following your instructions, and fitting into your service, the position may become more complicated.
What points may suggest responsibility comes back to you?
Responsibility may be more likely to come back to you if:
you agreed the job with the client;
you brought the other person onto the job;
you told them what work to do;
you controlled how the work should be done;
you provided the client instructions;
you supplied equipment, tools or materials;
you controlled timing, location or access;
you checked or supervised their work;
the client thought they were part of your service;
you paid them from the money you received from the client;
the work was part of the job you had undertaken;
the work was carried out for your benefit;
you could remove or replace them;
they were not genuinely dealing with the client as their own independent business.
No single factor decides the answer.
The full working arrangement matters.
Example: self-employed builder using a labourer
A self-employed builder agrees to complete renovation work for a client.
The builder brings in another self-employed labourer to help.
The builder tells the labourer what to do, where to work, what materials to move, and how the job should be completed. The client deals only with the builder. The labourer is presented as part of the builder’s team.
If the labourer carelessly leaves materials in a walkway and someone trips, the injured person may not only look at the labourer.
They may also look at the builder.
The argument may be that the labourer was carrying out the builder’s work, under the builder’s direction, as part of the service the builder agreed to provide.
Example: self-employed courier using a substitute driver
A self-employed courier accepts a delivery route and sends another driver to cover the work.
If the substitute driver causes injury while carrying out that route, the question may be who controlled the arrangement.
Was the substitute genuinely running their own independent delivery business?
Or
was the substitute carrying out the original courier’s work, using the original courier’s instructions, route, client arrangements or account?
If the original courier organised and controlled the work, responsibility may become more complicated.
This is why substitution clauses and real substitution arrangements need careful thought.
A right to substitute may support independence in some contexts, but it may also create practical risk if the substitute causes injury or damage and the arrangement is poorly documented.
Example: self-employed cleaner sending another cleaner
A self-employed cleaner agrees to clean commercial premises.
They send another cleaner to do the work.
If that cleaner uses unsafe methods, leaves a wet floor without warning, and a visitor slips, several questions may arise:
Who agreed the cleaning contract?
Who gave the cleaning instructions?
Who supplied the cleaning products?
Who controlled the method of work?
Did the client know a substitute would attend?
Was the substitute insured?
Was the substitute genuinely independent?
Who was responsible for warnings and safety?
If those questions are unclear, the risk may not be clear either.
Direct negligence: not only vicarious liability
This issue is not only about vicarious liability.
You may also face direct negligence risk if you personally failed to take reasonable care.
For example, responsibility may arise if you:
chose an obviously unsuitable person;
failed to check competence;
failed to check insurance;
gave unsafe instructions;
failed to explain site risks;
failed to supervise where supervision was needed;
allowed unsafe work to continue;
failed to warn the client or others;
supplied defective tools or equipment;
sent someone into a job they could not safely do.
In those situations, the argument may not simply be:
You are liable for what they did.
It may be:
You were negligent in how you selected, instructed, organised or controlled them.
That is a different but important risk.
Link with business liability for subcontractors
The same issue also affects businesses that use subcontractors or independent contractors.
Sometimes a business may assume it is safe because the person doing the work is “self-employed” or “independent”.
But if the business controls the work, creates the risk, gives unsafe instructions, integrates the person into its operations, or benefits from the work as part of its enterprise, the label may not be enough.
For the wider business-facing version of this issue, read:
Can a Business Be Liable for a Subcontractor or Independent Contractor?https://www.businesslegaladvice.co.uk/post/can-a-business-be-liable-for-a-subcontractor-or-independent-contractor
The same thinking can apply at a smaller level to self-employed people who bring others into their work.
If you organise the work, control the person, and benefit from what they do, you need to understand the risk.
Link with self-employed fleets
This issue can be especially important in delivery, transport, courier and fleet arrangements.
A business owner may use drivers who are described as self-employed. The drivers may use their own vehicles, routes or accounts. But if the business controls the work, allocates jobs, manages expectations, controls branding, or benefits from the delivery activity as part of its business, the position may not be simple.
For more on that risk, read:
Vicarious Liability and Self-Employed Fleets: Why Business Owners Need to Understand the Riskhttps://www.businesslegaladvice.co.uk/post/vicarious-liability-and-self-employed-fleets-why-business-owners-need-to-understand-the-risk
Although that article looks at fleets and business owners, the same practical warning
applies to smaller self-employed arrangements:
If you control someone else’s work, you may also carry risk for what happens during that work.
The substitution problem
Substitution is often used to support the idea that someone is genuinely self-employed.
But substitution also creates practical risk.
If you send someone else in your place, you need to think about:
whether the client allowed substitution;
whether the substitute is competent;
whether the substitute is insured;
whether the substitute understands the work;
whether the substitute knows the site risks;
whether the substitute is genuinely independent;
who is responsible if the substitute causes injury;
whether your own insurance covers substitute work;
whether the contract says you remain responsible.
A substitution clause may help show independence, but it does not automatically remove risk.
If the substitute causes injury or damage, someone may still ask who selected them, who controlled them, who benefited from their work, and who was responsible under the contract.
Insurance must be checked carefully
Insurance is central to this issue.
If you use another person, do not assume your insurance automatically covers them.
You may need to check:
whether your public liability insurance covers helpers or subcontractors;
whether substitutes are covered;
whether labour-only subcontractors are treated differently from bona fide subcontractors;
whether professional indemnity cover extends to work done by others;
whether employers’ liability insurance is needed;
whether the other person has their own insurance;
whether the policy requires written contracts;
whether the policy excludes uninsured subcontractors;
whether your contract requires evidence of cover.
This is where insurance becomes the belt and braces protection.
You may believe responsibility should sit with the other person, but if there is a dispute after injury or damage, the practical question may become whether there is insurance to respond.
Contracts should make the arrangement clear
If you bring someone else into your self-employed work, the arrangement should be clear in writing.
Important contract points may include:
whether substitution is allowed;
whether the client must approve substitution;
whether the substitute is your responsibility;
whether the substitute works independently;
who controls the method of work;
who supplies tools and equipment;
who carries insurance;
who is responsible for injury or damage;
whether indemnities apply;
who deals with the client;
who is responsible for health and safety;
what happens if the substitute causes loss.
A vague arrangement can create serious problems.
After an accident, everyone may try to shift responsibility.
The client may say you were responsible.
You may say the substitute was independent.
The substitute may say they were following your instructions.
Clear terms reduce that uncertainty.
Evidence to keep
If you use substitutes, helpers or subcontractors, keep evidence.
Useful evidence may include:
written agreements;
messages confirming the arrangement;
proof of insurance;
proof of competence or qualifications;
job instructions;
risk information provided;
photographs of the site;
records of who controlled the work;
records of who supplied equipment;
invoices;
payment records;
client approval of substitution;
accident reports if something goes wrong.
Evidence helps answer the practical question:
Was this person genuinely independent, or were they working under your control?
Practical checks before using another person
Before bringing in another self-employed person, substitute, helper or subcontractor, ask:
Am I allowed to use this person?
Are they genuinely independent?
Am I controlling how they do the work?
Are they insured?
Am I insured for their involvement?
Are they competent for the task?
Have I explained the risks?
Who provides the tools?
Who controls the work?
Who deals with the client?
What does my contract say?
What happens if they injure someone?
What happens if they damage property?
These are not only legal questions.
They are business protection questions.
Need advice about self-employed injury risks?
If you are self-employed, injury risk is not only about whether you personally get hurt.
It is also about who you use, who you control, who works under your arrangements, and whether your contracts and insurance protect you.
This may involve:
employment status;
vicarious liability;
direct negligence;
substitution;
subcontractors;
helpers;
public liability insurance;
contract terms;
client responsibility;
injury to others;
property damage.

Final point
If you are self-employed and use another person to help, substitute or subcontract, do not assume the risk disappears because they are also self-employed.
The real question is how the arrangement works in practice.
If they are genuinely independent, responsibility may sit with them.
But if you control their work, give instructions, organise the job, present them as part of your service, or benefit from their work as part of your own undertaking, responsibility may come back to you.
That is why self-employed people should treat substitutes, helpers and subcontractors carefully.
Check the contract.
Check the insurance.
Check the evidence.
Check who controls the work before something goes wrong.
