Personal Trainer Service Agreement UK | PT Client Contract
Working as a personal trainer without a written contract leaves you exposed to unpaid sessions, scope disputes, and cancellation headaches. A Personal Trainer Service Agreement sets out exactly what you will deliver, when payment is due, and what happens if a client cancels at short notice — before any of those problems arise. For self-employed PTs, the agreement also helps demonstrate genuine self-employment status, which matters under HMRC's employment status tests. If a client delays payment, your right to claim interest under the Late Payment of Commercial Debts (Interest) Act 1998 depends on having a valid commercial contract in place. Whether you work one-to-one, run group sessions, or provide online coaching, get your contract generated now and start every client relationship on solid ground.

Key clauses in a Consulting Agreement
Session Cancellation and Refund Policy
This clause defines how much notice a client must give to cancel or reschedule a session, and whether a fee is charged when they fail to do so. Without it, you have no contractual basis to charge for last-minute cancellations, which are among the most common financial losses for self-employed personal trainers in the UK.
Payment Terms and Late Fees
This clause specifies when payment is due, the accepted methods, and the interest rate applied to overdue invoices. Under the Late Payment of Commercial Debts (Interest) Act 1998, businesses can charge statutory interest of 8% above the Bank of England base rate on late commercial payments, but only where a contract exists that makes the debt legally enforceable.
Health Disclosure and Liability Limitation
This clause requires the client to disclose any relevant medical conditions before training begins and limits your liability for injury arising from undisclosed health issues. UK personal trainers have a duty of care under common law negligence principles, and this clause — combined with professional indemnity insurance — helps establish that you took reasonable steps to protect the client's safety.

Do I need a written contract as a self-employed personal trainer in the UK?
There is no legal requirement to have a written contract, but operating without one creates serious practical risks around unpaid fees, cancellations, and disputes over what was agreed. A written agreement also supports your self-employed status by documenting that you control your own working methods and are not under the client's direction — factors HMRC considers when assessing employment status.
Can I charge clients for missed sessions in the UK?
Yes, provided your contract includes a clear cancellation policy that the client agreed to before sessions began. UK contract law requires terms to be brought to a client's attention before the agreement is formed — adding a cancellation fee after the fact is unlikely to be enforceable. A signed service agreement with a defined cancellation window and fee structure gives you the legal standing to charge.
Should my personal trainer contract include a health and medical disclaimer?
Yes. A health disclosure clause asks clients to confirm they are medically fit to train and to notify you of any conditions that could affect their safety. This is standard practice recommended by bodies such as CIMSPA and REPs, and it supports your defence in any negligence claim by showing you took reasonable precautions before providing physical training services.
