What expenses can a self-employed personal trainer claim? Gym rent, equipment, CPD courses, insurance — with a worked tax calculation example for UK PTs.
Tax Essentials

- VAT Threshold Risk
- Low risk
- Industry Body
- CIMSPA
- Key Certifications
- Level 3 Diploma in Personal Training · First Aid certification
If you work as a self-employed personal trainer, you're responsible for reporting your income and paying tax through Self Assessment. Whether you train clients in a gym, at their home, outdoors, or online — the expenses you can claim reduce your tax bill, and gym rent alone can be a large deduction.
The key distinction for PTs: your own gym membership for personal fitness is not deductible. But renting gym space to train clients is. Getting this right makes a big difference.
What You Can Claim
| Expense | Examples | Typical Annual Cost |
|---|---|---|
| Gym/studio rent | Monthly rent to gym or studio for training clients (PureGym, private studios) | £2,400–£6,000 |
| Equipment | Kettlebells, resistance bands, dumbbells, yoga mats, boxing pads, TRX straps | £200–£800 |
| Insurance | Public liability + professional indemnity (Insure4Sport, Protectivity) | £50–£100 |
| CPD & training courses | Level 4 specialisms, nutrition courses, first aid renewal | £200–£600 |
| Travel to clients | Mileage to client homes, parks, outdoor sessions (45p/mile first 10,000) | £500–£2,000 |
| Branded clothing | Uniforms with your business logo (not plain activewear) | £100–£300 |
| Phone & internet | Smartphone, mobile data (business portion — typically 50–70%) | £150–£300 |
| Marketing | Website, social media ads, business cards, photography for content | £200–£600 |
| Professional memberships | CIMSPA registration (from £38/year) | £38–£180 |
| Accounting fees | Tax return preparation, bookkeeping | £100–£300 |
Gym Rent: The Biggest Deduction
How you pay for gym access determines your largest expense:
- Fixed monthly rent — typically £230–£550/month outside London, £1,200+ in central London. Fully deductible.
- Hourly hire — £18–£25/hour for studio space. Fully deductible.
- Commission/revenue share — the gym takes a percentage of your session fee (often 50%). The gym's cut is deductible as a business expense.
CPD Courses That Count
- Level 4 specialisms — sports nutrition, strength & conditioning, pre/post-natal training. Deductible because they build on your existing Level 3 qualification
- First Aid renewal — deductible, and usually required by insurers and gyms
- CIMSPA-endorsed workshops — deductible as professional development
Your initial Level 3 Personal Training qualification is not deductible — it's what made you a PT in the first place. Only ongoing training that improves your existing skills counts.
Expenses You Can't Claim
- Your own gym membership — if you have a personal membership for your own fitness, it's a personal expense, even if you're a PT. Only rent paid specifically to train clients qualifies
- Plain activewear — leggings, trainers, and gym tops you could wear outside work don't count. Only branded uniforms with your business logo qualify
- Your Level 3 qualification — the course that qualified you as a PT isn't deductible. Only CPD and specialisms count
- Commuting to your regular gym — travel to the same gym you work from daily isn't deductible. Travel to different client locations is
- Food and supplements — protein shakes, meal prep, and snacks during work aren't deductible, even if they're "part of the job"
Example: How Much Tax Does a Personal Trainer Pay?
Emma works as a self-employed PT, training clients at a local gym and in their homes. Here's her 2025/26 tax year:
| Item | Amount |
|---|---|
| Training income (gross) | £28,000 |
| Gym rent (£300/month × 12) | −£3,600 |
| Equipment, insurance, CPD | −£1,100 |
| Travel, phone, marketing, CIMSPA, accounting | −£1,800 |
| Taxable profit | £21,500 |
| Income Tax (after £12,570 personal allowance) | £1,786 |
| Class 2 NI (£3.50/week × 52) | £182 |
| Class 4 NI (6% on £12,570–£50,270) | £536 |
| Total tax + NI due | £2,504 |
Without claiming expenses, her tax + NI would be £4,194. Expenses — led by gym rent — save Emma £1,690.
Record Keeping Tips
Good records make your tax return straightforward and protect you if HMRC asks questions. See our full guide on what records to keep for more detail.
- Get receipts for gym rent — whether you pay monthly or per session, keep payment confirmations. If it's cash, get a written receipt from the gym
- Log every client visit with mileage — if you travel to homes, parks, or different gyms, record the address and distance. A mileage app makes this automatic
- Save CPD certificates and invoices — HMRC may ask you to prove a course improves your existing skills rather than teaching a new trade
- Keep CIMSPA and insurance renewal emails — these are easy to lose in your inbox. Move them to a tax folder the day they arrive
- Track session counts alongside income — record how many sessions you delivered each week and at which location. This makes it easy to cross-check against gym rent or commission deductions at year end
