20 Business Startup Essentials
16th August 2025
As a small business owner, growth often means getting extra help – but should you employ staff or hire freelancers?
Both options have their benefits, but they also come with different legal responsibilities, costs, and practical considerations.
This guide will help you understand the difference between an employee and a self-employed worker in the UK, when to hire an employee, and when freelancing might be the smarter choice.
The Legal Difference Between an Employee and a Self-Employed Worker
The terms employee and freelancer aren’t interchangeable – they have very different meanings in UK law.
- Employees work under an employment contract and are entitled to rights such as paid holiday, sick pay, and pension contributions.
- Self-employed workers (often called freelancers, sole traders or contractors) run their own business, usually work for multiple clients, and pay their own tax and National Insurance.
How to check status:
If you’re unsure whether a role is employed or self-employed, use HMRC’s Check Employment Status for Tax (CEST) tool. It’s designed to help you determine the correct employment status for tax purposes.

When to Hire an Employee
Employing staff can bring stability and help your business grow, but it’s a bigger commitment than using freelancers. You may have completed the Achiever Matrix exercise and decided that now is the time to get some extra help in.
It might also be time to hire if:
- You have regular, ongoing work that can fill a permanent role.
- You want someone to embed in your business and fully understand your processes.
- You need control over hours, methods, and location of work.
- You’re spending a lot on freelancers for work that would be more cost-effective in-house.
Your Legal Responsibilities as an Employer in the UK
If you decide to employ someone, there are legal steps you must take:
- Register as an employer with HMRC before paying staff.
- Workplace pension – automatically enrol eligible employees and make contributions.
- Employers’ liability insurance – at least £5 million cover is legally required in most cases.
- Written employment contract – give this to your employee on or before their first day.
- Payroll and PAYE – deduct tax and National Insurance and report to HMRC.
- Health and safety compliance – meet your legal obligations to protect staff.
Pros and Cons: Employee vs Freelancer
| Hiring an Employee | Hiring a Freelancer | |
|---|---|---|
| Control | High – you set hours, methods, and location | Lower – freelancer decides how and when to work |
| Commitment | Long-term commitment | Flexible, hire as needed |
| Costs | Salary + NI + pension + benefits | Agreed rate only – no NI or pension costs |
| Loyalty & Culture | Can build strong loyalty and team culture | Less connected to your business |
| Flexibility | Lower – harder to reduce hours quickly | High – stop or scale work easily |
| Legal Risk | More compliance responsibilities | Risk if wrongly classed – check status carefully |
Checklist: Deciding Between Employing or Freelancing
Ask yourself these questions before making your decision:
- Do I have enough consistent work to justify hiring?
- Is flexibility more important than control right now?
- Can my cash flow comfortably cover ongoing employment costs?
- Do I want to invest in someone’s long-term development?
- Have I checked the role’s employment status with HMRC’s CEST tool?
- Am I prepared for the legal and admin responsibilities of being an employer?
Final Thought
The decision between employing and freelancing isn’t just about cost – it’s about what your business needs right now and where you want it to be in the future.
If you’re unsure, map out your workload, financial position, and growth goals before taking the leap. A clear plan will help you choose the right path and avoid costly mistakes.
