Can A Sole Trader Have Employees In The UK?

Thinking about taking on your first employee as a sole trader? Good news - you absolutely can. Hiring staff is a big milestone and often the quickest way to grow your capacity, improve service levels and open up new revenue.

That said, once you employ someone you’ll take on a set of legal obligations under UK law. With the right setup, it’s straightforward - and getting your legal foundations right now will save headaches later.

Below, we explain how sole traders can employ staff, the legal steps to follow, and the essential documents and policies to have in place so you’re protected from day one.

Can A Sole Trader Have Employees In The UK?

Yes - a sole trader can employ staff in the UK. There’s no legal cap on the number of employees you can have as a sole trader. Practically, the question isn’t “how many employees can a sole trader have?” but “how many can you manage compliantly and affordably?”

When you employ someone as a sole trader, you’ll be personally responsible for meeting your duties as an employer. That includes paying wages and tax through PAYE, providing statutory rights, following working time rules, and keeping your workplace safe. If you put solid processes and contracts in place early, scaling from one employee to several is much easier.

You’ll also want to choose the right type of help for each role. Some jobs are best done by employees (where you control the work, hours and methods), while project-based or specialist roles may suit contractors. To reduce misclassification risk, make sure you understand employment status tests before you decide.

How To Employ Someone As A Sole Trader (Step-By-Step)

Here’s a practical sequence you can follow when hiring your first worker as a sole trader.

1) Define The Role And Employment Status

• Clarify tasks, skills, location, working hours, supervision and how success will be measured.
• Decide whether the role should be an employee, worker, or contractor (use status tests like control, mutuality of obligation and substitution).
• Choose full-time, part-time or zero-hours depending on your needs, then budget for salary, National Insurance, pension, holiday pay and employer costs.

2) Register As An Employer With HMRC

• Before the first payday, register for PAYE so you can deduct Income Tax and employee National Insurance and pay employer NICs.
• Set up payroll software that supports Real Time Information (RTI) reporting to HMRC each pay period.

3) Right To Work Checks And (If Applicable) DBS

• Carry out right to work checks for every new hire. Keep copies of acceptable documents and follow Home Office guidance.
• If your industry involves regulated activity (for example, certain roles in education or care), you may need a DBS check before they start work.

4) Issue A Written Statement And Employment Contract

• Employees are entitled to a written statement of particulars by or on day one.
• It’s best practice to use a tailored Employment Contract that covers duties, pay, hours, place of work, holiday, sick pay, probation, confidentiality, IP, restrictive covenants and termination.
• Use a clear probation period to test the fit and set expectations - our guide to probation periods outlines typical lengths and rules.

5) Set Up Payroll, Pensions And Statutory Deductions

• Run payroll each pay period, calculate tax and NICs, send RTI submissions, and pay HMRC.
• Assess the employee for automatic enrolment under the Pensions Act 2008. If eligible, enrol them in a workplace pension and make employer contributions.
• Handle statutory payments correctly (SSP, SMP, etc.) and keep accurate records.

6) Arrange Insurance And Health & Safety

• Most employers must hold Employers’ Liability Insurance under the 1969 Act - see our guide to employers’ liability insurance for who needs it and how much cover is required.
• Set up basic health and safety processes appropriate to your work (risk assessments, induction, equipment maintenance, training, first aid).

7) Provide Policies, Training And Onboarding

• Give new starters your core policies on conduct, disciplinary and grievance, health and safety, data protection and equality.
• Bundle these into a concise, practical Staff Handbook and ensure staff sign to acknowledge receipt.
• Deliver role-specific training and keep a record of completion.

8) Manage Working Time, Holidays And Breaks

• Plan rotas and rest periods in line with the Working Time Regulations and your sector needs. Our summary of working time rules covers maximum weekly hours, night work and opt-outs.
• Make sure you’re giving the right rest and lunch breaks; see the rules on employee breaks.
• Track holiday accrual and carryover, including part-time pro‑rata calculations.

9) Pay Correctly And Keep Clean Records

• Always meet or exceed the National Minimum Wage/National Living Wage for the employee’s age and status.
• Only make lawful deductions and explain them clearly on payslips - our guidance on wage deductions explains what’s permitted.
• Maintain personnel files, right to work evidence, training records, and payroll data for the required retention periods.

Employment Laws Sole Traders Must Follow

Once you hire staff, you’re an employer under UK law; the same core rules that apply to larger businesses apply to you too. Here are the key areas to get right.

Employment Rights Act 1996 (Written Terms, Notice, Pay)

You must provide core written particulars on or before day one, pay wages in full and on time, and meet statutory notice requirements. Make sure your contract reflects any enhanced benefits you offer so there’s no confusion later.

National Minimum Wage Act 1998 And Working Time Regulations 1998

You must pay at least the current minimum or living wage and follow the Working Time Regulations (maximum weekly hours, rest breaks and paid holiday). If you rely on opt-outs for 48-hour limits or use night shifts, document consents and monitor hours closely to manage fatigue and safety risks.

Equality Act 2010 (Non-Discrimination)

Avoid discrimination throughout recruitment, employment and dismissal. Have a fair, consistent process for hiring and promotions, make reasonable adjustments for disabilities, and use a clear, accessible grievance procedure.

Health And Safety At Work Etc. Act 1974

Even if you work from a small workshop or your home office, you must take reasonable steps to keep staff and visitors safe. Conduct risk assessments, keep equipment safe, and train employees on hazards and safe systems of work.

Data Protection (UK GDPR And Data Protection Act 2018)

As an employer you’ll handle personal data (passports for right to work, bank details, performance notes). You need a lawful basis for processing, secure storage, limited retention and transparency with staff. It’s sensible to have a simple employee privacy notice and align with a practical Data Protection Pack so you meet your obligations without overcomplicating things.

Pensions Act 2008 (Auto-Enrolment)

Assess each employee for eligibility, enrol them when required, communicate their rights, and pay employer contributions on time. Keep clear records of assessments and opt-outs.

Young Workers And Industry-Specific Rules

If you’re hiring someone under 18, additional rules apply on hours, rest and permitted work. Review the rules for hiring young workers and check if your sector has extra licensing or safety requirements.

Essential Employment Documents And Policies

Strong paperwork makes day-to-day management simpler and reduces disputes. At a minimum, sole traders employing staff should have:

• Employment Contract - tailored to the role (salary, hours, place of work, duties, probation, IP and confidentiality, restrictive covenants, notice, and termination). A professionally drafted Employment Contract sets expectations and is easier to enforce.
• Offer Letter And Right To Work Checklist - formalise the offer, start date and any conditions, and keep compliant onboarding records.
• Staff Handbook - a practical compilation of your core rules (conduct, disciplinary, grievance, holidays, sickness, equal opportunities, data protection, health and safety). Our Staff Handbook helps keep everything in one place.
• Workplace Policies - depending on your business, you may also need policies for social media, expenses, home working, and a concise Workplace Policy framework to support consistent decisions.
• Privacy And Data - an employee privacy notice and internal data handling rules (access controls, retention schedule, data breach steps). If you also collect customer data online, pair this with a compliant Privacy Policy.

Avoid generic templates for roles that touch clients, handle sensitive information or create IP - your risks are unique, and tailored drafting means fewer gaps and surprises.

Practical FAQs For Sole Traders Hiring Staff

How Many Employees Can A Sole Trader Have?

There’s no statutory limit. You could employ one person or a team of twenty - the key is whether your finances, systems and compliance can scale. If you plan rapid growth, you might later consider moving to a limited company for limited liability and potential tax and investment advantages. You can make that change when it makes sense; it doesn’t stop you hiring now.

Can I Use Zero-Hours Or Part-Time Contracts?

Yes, if the pattern of work is irregular or seasonal. Ensure the contract reflects the reality of the relationship, sets out pay for time worked, holiday accrual, and any exclusivity terms that comply with UK law. Track hours accurately and pay promptly.

Do I Need To Pay Overtime?

There’s no general right to overtime pay unless your contract says so, but average weekly hours must comply with the Working Time Regulations. If you agree overtime rates, write them clearly in the contract or handbook. If you regularly rely on extra hours, keep a close eye on rest and night work limits as outlined in the working time rules.

What About Deductions For Uniforms, Breakages Or Till Shortages?

Deductions are tightly regulated. Only make deductions that are required by law, authorised by the contract or with prior written consent - and never take pay below the National Minimum Wage unlawfully. Our guide to wage deductions explains the common pitfalls.

Do I Need A Probation Period?

It isn’t legally required, but it’s smart to include one so you can assess performance and cultural fit with shorter notice terms during the initial months. Make sure your contract and handbook set out clear objectives and review points; see our overview of probation periods for useful benchmarks.

Should I Hire A Contractor Instead?

Contractors can be great for specialist or project work, but the label doesn’t decide status - the reality of the relationship does. If you control hours and methods, require personal service, and provide ongoing work, the individual may actually be an employee or worker. Review the status tests and draft the right agreement for the relationship.

Can I Employ Someone Under 18?

Yes, but additional rules apply around working hours, rest, night work and permitted tasks. Build rotas and supervision with these limits in mind and check the guidance on hiring young workers.
