Jasper McDermott made a deliberate bet.
When Jasper joined UNTIL Liverpool Street in January 2024, he didn't just change gyms. He walked away from 90% of his existing client base - on purpose. He'd been working out of a CrossFit gym for years: highly capable, deeply ambitious, but isolated. "When the classes aren't on, it's just me in this big empty gym."
He wanted to rebuild at a higher price point, around people operating at the highest level. So he took the bet. Ten months later, his session volume had grown by 87.5%.
Jasper's one word for UNTIL: opportunity. Not growth. Not community. Opportunity:. "If you want to take it, if you want to be ready for it, then by all means."
Simon Bloch left a commercial gym when a new commission structure cost him £1,000 a month.
Simon spent three years at Virgin Active in Mayfair. He built a strong business. He learned the ropes. And then the gym changed how it paid him. "If the sun was shining in Italy and my clients went on holiday, I would lose a grand a month. The service I deliver is still the same."
He'd heard about UNTIL two years earlier, but the timing wasn't right. This time, it was. He hired our gym space, structured his day from 6 am to 2 pm, and spent his afternoons working on the business rather than just in it. He raised his rates. The majority of his clients followed him. Within five months, he'd gone from 23 sessions a month to 108 - becoming one of the top session-volume practitioners on the platform during the summer, when clients are typically hardest to retain.
Simon's one word for UNTIL: opportunity. "I have all the opportunities in front of me. I just have to choose what I want to do with it."

Four steps to running your own practice.
From your first conversation with our membership team to your first session, most practitioners are up and running within two weeks.
Fill in a short application. Our team will be in touch within one working day to set up a call. No hard sell, just honest answers about whether UNTIL is the right fit for where you are.
£149/mo gives you full club access across all four locations, community membership, and the ability to book space. No joining fee. Cancel with 30 days' notice.
Buy credit bundles and book gym floor time when you need it. Sessions starting from as little as £27/hr. Same-day bookings available.
Cross-referrals from 500+ practitioners — from personal trainers and physios to doctors and nutritionists. 90% of members say the UNTIL community has grown their business.
500+ practitioners. One building. All referring each other.
When a physio treats a client with chronic back pain, they need a PT to continue their recovery. When a GP refers a patient for lifestyle change, they need a trainer they trust. At UNTIL, those referrals happen in the corridor, not in a directory.
This is what Jasper McDermott calls the compounding effect of proximity. What Simon Bloch describes as the football principle - when you play with better people, your own level rises. You're not just renting a gym floor. You're embedding yourself in a clinical ecosystem that actively grows your practice.
Who you'll be working alongside
Three things most PTs ask us first.
Honest answers, with real numbers.
Will I fill my diary here?
UNTIL isn't a lead-generation platform - it's a growth engine for PTs who are already building.
What you get is 500+ health professionals under one roof - physios, doctors, osteopaths - who refer to practitioners they trust and work alongside. The referrals happen in the corridor, not through a directory.
There's also Health Concierge, our opt-in matching service that connects members of the public to the right UNTIL practitioner by specialism.
The biggest predictor of whether you'll thrive here: you're already building a client book, and you're ready to grow it now.
Simon Bloch: 23 → 108 sessions in under 6 months.
AM I READY FOR THIS?
If you've got clients, a session rate you're prepared to defend, and the confidence to run your own practice, you're ready.
If you're not sure, our membership team will tell you honestly on the call. No hard sell either way.
If UNTIL isn't the right fit for where you are right now, we'll say so.

HOW IS THIS DIFFERENT FROM OTHER GYM RENTALS?
Three things most gym rental options don't offer together.
No revenue share - ever. Most gyms that offer PT space take a cut of every session. UNTIL doesn't, at any tier or any session volume.
Premium equipment without the lease: Eleiko, Prime and Atlantis, booked by the hour.
And a clinical referral network, not just a room: 500+ practitioners across 50+ specialisms in the same building. 30-day notice. No lease. No lock-in.

Gym spaces to rent: your questions answered.
How much does it cost to rent gym space at UNTIL?
Thrive membership is £149/mo and gives you full club access across all four London locations. On top of that, you buy credit bundles to book space by the hour. Credits start at £27/hr on a 2,000-credit bundle, up to £43/hr on an introductory bundle. Most active PTs running 8+ hours a week use the 2,000 or 5,000-credit bundle.
What equipment is available in the UNTIL PT studios?
All UNTIL gym floors are equipped with Eleiko barbells and bumper plates, Prime Fitness cable stations, and Atlantis resistance machines. Equipment is maintained to clinical standards and replaced on a rolling schedule. Full equipment lists for each location are available in the brochure.
Can I use multiple UNTIL locations?
Yes. Your Thrive membership gives you access to all four UNTIL locations - Soho, Marylebone, Liverpool Street and Canary Wharf. Credits can be used at any location. Some practitioners split their week across two locations to reach different client catchments.
Do I need to bring my own clients to UNTIL?
Yes, you run your own practice and bring your own clients. UNTIL isn't a referral agency. What UNTIL does provide is a community of 500+ health professionals who naturally refer to practitioners they work alongside. 90% of members say the community grew their business. Simon Bloch went from 23 sessions a month to 108 in under six months - primarily through cross-referrals from other UNTIL practitioners.
What is the difference between Thrive and Teams membership?
Thrive is the individual membership at £149/mo - suited to solo practitioners. Teams is designed for practices with multiple practitioners: £50/mo for the team account plus £99/mo per team member. Teams membership is how practices like Kaizen Physio grew from 2 to 8+ practitioners within UNTIL.
How does the credit system work?
Credits are used to book gym floor space by the hour. You buy bundles in advance - the more credits you buy, the lower the rate per hour. Bundles range from introductory (£43/hr) to 5,000 credits (lower per-hour rate). Credits don't expire. You can book same-day, subject to availability. There's no minimum usage and no penalty for booking less in quieter months.
How much notice do I need to cancel?
30 days' written notice. No minimum term, no lease, no penalty. Credits don't expire. UNTIL is designed for independent practitioners who need flexibility - not another long-term commitment.
How quickly can I book my first session?
Most practitioners complete their onboarding call with our membership team within 2–3 days of applying and are booking space within the first week. Same-day bookings are available, subject to room availability. There's no waiting list for Thrive membership at present.
