Hiring Your First Employee: Advice for Small Business Owners
A practical guide to hiring your first employee in the UK: when to hire, what it really costs, the legal steps in order, and where expert advice saves money.
In this article8 sections
Hiring your first employee is the point where a business stops being a job you do and becomes something that can grow without you. It is also the moment the legal and financial obligations step up sharply. This guide walks through when to hire, what it really costs, the steps the law requires, and where a short session of business advice online from someone who has done it can save you from expensive mistakes.
When is the right time?
Owners tend to hire either far too late, when they are already burned out, or too early, when the work does not yet exist to fill the hours. A few signals that it is genuinely time:
- You are turning down paid work, or delivering it late, because of capacity.
- You can list at least 20 hours a week of repeatable tasks that someone else could do.
- The business can cover the full cost of the role (see below) for six months even if revenue dips.
- The tasks you would hand over are lower value than the work you would do with the freed time.
If you cannot tick the third point, consider a freelancer or part-time contractor first. It is a lower-commitment way to test whether the role exists.
What it actually costs
The advertised salary is not the cost. A rough rule of thumb is to add 20–30% on top. For a role at £28,000 a year, budget for:
| Item | Approximate annual cost |
|---|---|
| Salary | £28,000 |
| Employer National Insurance | Several thousand pounds, depending on current thresholds |
| Pension contribution (minimum 3% of qualifying earnings) | Roughly £600–£800 |
| Employers' liability insurance | £100–£300 |
| Equipment, software, desk | £500–£2,000 |
| Recruitment and your own time | Varies, often £1,000+ |
Check current rates on GOV.UK before you set a budget, because thresholds change each tax year. Then add holiday cover, sick pay and the several weeks of reduced productivity while they learn the job.
The legal steps for hiring your first employee, in order
The process is not complicated, but the steps have to happen in the right sequence.
- Decide on employment status. Employee, worker or self-employed contractor each carry different rights and tax treatment. Getting this wrong is one of the most common and costly errors.
- Register as an employer with HMRC. Do this before the first payday; it can take a couple of weeks to receive your PAYE reference.
- Check the right to work in the UK. You must do this for every hire, and keep a record.
- Get employers' liability insurance. This is a legal requirement from day one, with a minimum of £5 million cover.
- Issue a written statement of employment particulars. The main terms must be given on or before the first day.
- Set up a pension scheme and auto-enrol eligible staff.
- Run payroll. Report to HMRC in real time, every time you pay.

Writing the job description
Write down the outcomes, not just the tasks. "Manage the inbox" is a task. "Every customer enquiry gets a reply within one working day" is an outcome you can measure and give feedback against. Include the hours, location, pay range and who the person reports to. Keep the list of requirements to what is genuinely essential; long wish-lists put off good candidates and attract people who exaggerate.
Recruiting without an HR department
For a first hire, you do not need a recruitment agency. Post on a mainstream job board, tell your network and your existing suppliers, and ask customers if they know anyone. Shortlist on evidence of having done similar work, not on how polished the CV looks.
Interview with a structured set of questions you ask everyone, and score answers straight after each conversation. For practical roles, set a short paid task; 30 minutes of real work tells you more than an hour of talking. Take up references and actually phone them.
Where owners go wrong
- Hiring a copy of themselves. You need someone good at the things you are bad at or bored by.
- No probation period. Three to six months, with a review at the midpoint, protects both sides.
- Vague onboarding. Write a two-week plan before they start, even if it is a single page.
- Avoiding hard conversations. If it is not working at week six, say so, kindly and clearly. Small businesses cannot carry a poor fit.
- Misclassifying a contractor. If you control their hours, provide their equipment and they work only for you, they are probably not self-employed, whatever the contract says.
When to get advice on hiring your first employee
You do not need a lawyer on retainer to hire one person, but a focused conversation with an HR consultant, an accountant or an owner who has built a team can be worth a great deal. Typical first-hire questions a consultant can answer in 30 minutes:
- Is this a worker or an employee, and what does that change?
- Does my draft contract have the clauses I actually need?
- How should I structure pay and a review so that it motivates without over-committing?
- What is a sensible probation plan for this role?
If you have not already tested whether the business can sustain the role, reading about how to validate a business idea before you commit is worthwhile, and if you have a mentor, our list of questions to ask a business mentor includes several on first hires.
A worked example: a sole-trader electrician in Bristol wanted to take on an apprentice. A 30-minute session with an HR consultant covered apprenticeship funding, the correct minimum wage band, and what to put in a written statement. It cost less than one hour of his own labour rate and avoided two errors that would have cost far more.
Summary
Hiring your first employee is a legal process with a clear checklist, and a management challenge with no checklist at all. Budget for the full cost, not the salary. Register, check, insure and document before day one. Hire for outcomes, run a real probation, and have the awkward conversations early.

Frequently asked questions
What do I legally need before hiring my first employee in the UK?
You need to register as an employer with HMRC, check the person's right to work, hold employers' liability insurance, give a written statement of terms on or before day one, set up a workplace pension and run payroll with real-time reporting. GOV.UK and ACAS both publish step-by-step guides.
How much does a first employee really cost beyond salary?
Budget roughly 20–30% on top of the salary for employer National Insurance, pension contributions, insurance, equipment and recruitment. Then allow for holiday and sickness cover and a period of lower productivity while they learn the role.
Should my first hire be an employee or a contractor?
If the work is ongoing, you set the hours and you supervise how it is done, the person is likely an employee or worker regardless of what the contract calls them. A contractor is appropriate for defined, project-based work where they control how and when it is delivered. Get advice if you are unsure, because misclassification is expensive to unwind.
