Payment Processing for Gyms & Fitness Studios UK
Updated July 2026
Exclusive Rates From as Low as 0.26%
Gyms and fitness studios face a payment challenge that most retailers never encounter: members pay in at least two different ways, through a recurring monthly membership and a one-off card payment at the desk for classes, personal training, or merchandise. Getting both right, without paying for two separate systems, is where most gym owners waste money.
Key Takeaways
- ✓ Most gym members pay by Direct Debit for memberships, but your card terminal still needs to handle walk-in class bookings, personal training sessions, and retail sales quickly and reliably.
- ✓ Sumup and Square both charge 1.69% per transaction with no monthly fee, making them low-risk starting points for smaller studios with modest card volumes.
- ✓ Dojo offers next-day settlement by 10am, which matters when you carry stock (supplements, kit) and need cash flow to reorder quickly.
- ✓ If your gym takes over £10,000 a month by card, a merchant account with a negotiated rate (typically 0.6% to 0.9% for debit cards) will save you more than a flat-rate terminal every month.
- ✓ Always separate your membership billing platform (GoCardless, Glofox, Mindbody) from your card terminal provider. Bundling them rarely saves money and creates a single point of failure.
What Does a Gym or Fitness Studio Need from a Card Machine?
Speed matters at reception. A busy gym can see 40 or 50 members arriving in a 20-minute window before a popular class. Your card terminal needs to process a contactless payment in under two seconds and print or send a receipt without holding up the queue. Terminals with a slow boot time or unreliable Wi-Fi connections cause real problems here. A 4G-enabled machine such as the Dojo Go or Zettle Reader 2 paired with a phone hotspot will keep you running even if your broadband drops.
Battery life and portability matter more than most gym owners expect. Personal trainers moving between the gym floor, the studio, and outdoor sessions need a reader that lasts a full working day without charging. The Zettle Reader 2 lasts around nine hours of active use. The Sumup Air claims a similar figure. For front-desk use, any countertop terminal works, but if you run bootcamps or outdoor fitness events, a compact wireless reader is essential. Equally important is the ability to take payments for variable amounts. Personal training sessions at different price points, class passes, and nutritional supplements all need a simple way to key in a custom amount without fiddling through menus.
Fee Comparison: Best Options for Gyms & Fitness Studios
| Provider | Transaction Fee | Monthly Cost | Verdict |
|---|---|---|---|
| Dojo | From 1.4% (negotiable above £10,000/month) | From £20/month (Go terminal lease) | Best for established gyms wanting fast settlement and a reliable 4G terminal |
| Zettle by PayPal | 1.75% for first £2,000/month, then 1.00% | £0 (reader purchase, from £29) | Good for smaller studios or PTs who want zero monthly fees and strong app reporting |
| Sumup | 1.69% per transaction, all UK cards | £0 (reader from £39 + VAT) | Simple flat rate suits low-volume studios; no long-term contract required |
| Square | 1.75% in-person, 2.5% manually keyed | £0 (reader from £19 + VAT) | Strong point-of-sale app for gyms selling merchandise alongside memberships |
Our Top Pick for Gyms & Fitness Studios
Dojo is the strongest all-round choice for most gyms taking more than £5,000 a month by card. Its headline rate starts at 1.4% per transaction, and that rate is negotiable if your monthly card volume exceeds £10,000. More importantly, Dojo settles funds by 10am the next business day, seven days a week. For a gym that sells supplements, branded kit, or class passes in bulk, that cash flow certainty makes a genuine difference to stock management.
The Dojo Go terminal runs on 4G as well as Wi-Fi, so a broadband outage at 6am on a Monday morning will not stop you processing payments during your busiest hour. The machine itself is rented rather than purchased, which means replacements and repairs are covered. The main honest negative is the contract: Dojo typically requires an 18-month agreement, and early exit fees apply. If your gym is very new or your card volumes are unpredictable, that commitment carries risk. For an established studio with a stable member base, however, the rates and reliability justify the contract.

Runner-Up Options
Zettle by PayPal
Zettle suits smaller fitness studios and independent personal trainers who want a capable reader without a monthly standing charge. The Zettle Reader 2 costs £29 plus VAT for new accounts and charges 1.75% per transaction on the first £2,000 of monthly card sales. Above that threshold the rate drops to 1.00%, which is competitive for studios with moderate volumes. The accompanying app handles product libraries well, so you can set up class types, session packs, and retail items as separate line items and track what is selling. Settlement typically arrives in your bank account within one to two business days via PayPal, which is slightly slower than Dojo. Zettle does not charge a monthly fee and has no minimum contract, making it easy to start and easy to leave if your circumstances change.

Sumup
Sumup offers a genuinely straightforward flat rate of 1.69% on all UK card transactions, with no monthly fee and no contract. The Sumup Air reader costs £39 plus VAT and connects to your phone via Bluetooth. For a gym that processes relatively low card volumes, perhaps under £3,000 a month, the simplicity of a single percentage fee is appealing because there are no surprises. The honest drawback is that Sumup's transaction rate becomes less competitive as your volumes grow. A gym taking £15,000 a month would pay around £254 in fees at 1.69%, whereas a negotiated merchant account rate of 0.75% would cost around £113 for the same volume. Sumup works best as a starter solution or for personal trainers running outdoor sessions where portability outweighs cost efficiency.

Frequently Asked Questions
What is the best card machine for a gym?
Dojo is the best card machine for most established gyms in the UK. It offers next-day settlement by 10am, a 4G-enabled terminal that works if your broadband fails, and transaction rates starting at 1.4% that can be negotiated lower above £10,000 monthly card volume. Smaller studios with lower volumes may find Zettle or Sumup cheaper overall.
Do I need a separate system for gym membership payments?
Yes, in most cases you do. Card terminals process one-off payments at the desk, but recurring monthly memberships are handled more reliably by a Direct Debit platform such as GoCardless or a gym management system such as Glofox or Mindbody. Using a card terminal alone for recurring memberships creates failed payment problems and higher processing costs.
Can I take card payments for personal training sessions without a monthly fee?
Yes. Both Sumup and Zettle charge no monthly fee and no contract. You pay only when you take a payment: 1.69% per transaction with Sumup or 1.75% with Zettle on the first £2,000 of monthly sales. For a personal trainer taking £1,500 a month by card, that means roughly £25 to £26 in fees per month with either provider.
How quickly will card payments reach my bank account?
Settlement speed varies by provider. Dojo pays out by 10am the next business day, seven days a week. Zettle typically settles within one to two business days via PayPal. Sumup usually pays out within one to three business days. For gyms with tight cash flow or regular stock purchases, Dojo's guaranteed next-morning settlement is the practical advantage.
Is it worth negotiating card processing rates for a gym?
It is worth negotiating if your gym takes more than £8,000 to £10,000 a month by card. At that volume, moving from a flat rate of 1.69% to a negotiated debit card rate of around 0.75% saves roughly £94 per month on £10,000 of card sales. That is over £1,100 a year, more than enough to justify the conversation with a provider or a broker.
