One of the biggest decisions for any personal trainer is whether to work as an employee or become self-employed. While self-employment offers greater earning potential, employed roles provide financial stability, employment benefits and a consistent client base.
This guide compares both career paths to help you decide which is right for you.
Why Choose Self-Employment?
Many personal trainers choose self-employment for the flexibility and uncapped earning potential. Established PTs in London with a loyal client base can earn £60,000–£100,000+ per year, while setting their own hours and choosing the clients they work with.
However, higher earnings come with greater financial risk and additional business costs.
The Real Costs of Being Self-Employed
Before becoming self-employed, budget for ongoing expenses including:
- Gym floor rental: £300–£800 per month
- Public liability insurance: £100–£200 per year
- Professional indemnity insurance: £150–£300 per year
- CIMSPA membership: £100–£200 per year
- Continuing Professional Development (CPD): £300–£1,000 annually
- Marketing and administration: £100–£500 per month if outsourced
These costs need to be covered before you begin generating profit.

When Should You Go Self-Employed?
One of the biggest mistakes new trainers make is becoming self-employed before building a reliable client base.
A good time to make the move is when you have:
- 8–10 regular clients prepared to train with you
- A consistent source of referrals
- Around three months of savings to cover business costs while your client base grows
For many trainers, this significantly reduces the financial risk during the first year.
The Hybrid Approach
An increasing number of fitness professionals combine employed and self-employed work.
By working part-time for a gym while building a private client base, you benefit from a guaranteed income, access to new members and the opportunity to increase your earnings without relying entirely on one source of income.
Which Option Is Right for You?
If you value predictable income, paid holiday and career progression, an employed role may be the better choice.
If you're comfortable running your own business and already have a strong client base, self-employment can offer substantially higher earning potential.
Many successful PTs start employed, gain experience and build a reputation before making the transition.
