Introduction: Why We Chose Third Space Clapham Junction
After publishing reviews of Bow Lane Dental Group, The Neem Tree Dental Practice, and Brooks & Brooks salon, we wanted our fourth review to tackle a category that generates fierce debate among Londoners: gyms. And in the premium gym market, few names provoke as much discussion as Third Space.
Third Space Clapham Junction is the brand’s 12th London club, housed within the Grade II-listed former Arlington & Hobbs department store — a 1920s landmark being reimagined as a luxury mixed-use development. With membership starting at approximately £220 per month and a waitlist that has, at times, been in effect, this is unapologetically a premium offering. The question is whether it justifies the price.
We examined over 100 Trustpilot reviews specific to the Clapham Junction location, cross-referenced member feedback on Fishbowl, analysed press coverage from Leisure Opportunities and Sotheby’s Realty, and assessed the facilities, classes, and membership structure. This is the most comprehensive Third Space Clapham Junction review available.
Location & Getting There
Third Space Clapham Junction sits on Lavender Hill, within the reimagined Arlington & Hobbs building — one of Clapham Junction’s most recognisable landmarks.
By Train: Clapham Junction station is approximately a two-minute walk. As one of the busiest railway stations in Europe, it offers connections across South London, Surrey, and into central London via Southern, South Western Railway, and London Overground services. Victoria is roughly ten minutes away by train.
By Bus: Lavender Hill is served by multiple bus routes including the 77, 87, 156, 170, 219, 295, 319, 345, and G1.
By Car: Limited on-street parking is available. The gym’s location near a major transport hub makes public transport the more practical option for most members.
Why the Location Matters: Clapham Junction’s extraordinary transport connections mean this gym draws members from a broad catchment — Battersea, Wandsworth, Balham, Putney, and even commuters passing through the station. The two-minute walk from the platform to the gym floor makes pre-work and post-work sessions genuinely convenient.
First Impressions & Atmosphere
The word that appears most frequently in member reviews is “hotel.” One Trustpilot reviewer described the experience as “honestly hotel vibes,” and this assessment is echoed repeatedly across platforms. The 1920s architecture has been sympathetically restored, with a bespoke staircase designed around the original structure, a spacious lounge area finished in natural stone and timber, and workout spaces that blend historical charm with contemporary design.
The changing rooms are stocked with fluffy towels, fully loaded showers with Cowshed products, GHD hair tools, moisturiser, and deodorant. Several members note that you could arrive with nothing beyond your gym kit and leave looking presentable for a dinner reservation.
The gym floor itself is flooded with natural light — a detail that members consistently highlight as distinguishing Third Space from basement-level competitors. The overall atmosphere is described as clean, spacious, and respectful without being pretentious.

Classes & Training

- Reformer Pilates — Consistently cited as a standout offering. Multiple members describe the Reformer classes as “worth every penny” on their own
- Hot Yoga — Dedicated hot studio with controlled temperature

The Team
General Manager — Sebastian James: Described the club as “a sanctuary for those who seek the pinnacle of physical and mental wellness in an environment that blends historical charm with state-of-the-art facilities.”
Personal Trainers: Third Space requires all personal trainers to undergo intensive, industry-leading education. The Clapham team includes specialists in strength and conditioning, functional training, combat sports, and rehabilitation. Trainers mentioned in reviews include Jack (gymnastics and Muay Thai background), Brooke (basketball at Loughborough University), Ryan (strength training and martial arts), and Daniel (Loughborough and St Mary’s University background).
Class Instructors: Across all Third Space locations, instructors receive consistent praise. Members describe them as “enthusiastic,” “supportive,” and able to push clients whilst remaining encouraging. The Reformer Pilates instructor Ellie is specifically named by Clapham members.
Concierge Team: The front-of-house staff are referred to as “concierges” rather than receptionists — a deliberate choice that reflects the club’s hospitality approach. They are consistently described as friendly, helpful, and professional.
Housekeeping: Unusually for a gym review, multiple members specifically praise the housekeeping team for maintaining spotless facilities throughout the day.
Membership & Pricing
Third Space is unambiguously positioned at the luxury end of London’s gym market. Let us be direct about the numbers.
Single Club Membership (Clapham Junction only): From approximately £220–£252 per month, plus a £100 joining fee.
Multi-Club Membership (all locations, excluding Mayfair): From approximately £245 per month.
What’s Included: Unlimited classes (100+ per week across all clubs), gym floor access, sauna, steam room, recovery tools (Normatec, Theragun), towels, Cowshed products, GHD tools, on-demand app access, up to 3 guest passes per visit.
What Costs Extra: Personal training sessions, spa treatments, sports medicine consultations, premium locker rental, laundry service.
Membership Flexibility: Members can freeze their membership for up to six months per year in monthly increments. Transfers between clubs are subject to availability.
Corporate Discounts: Available — several Fishbowl users mention receiving discounts through their employer (PwC, Deloitte, and similar firms are cited).
The Value Question: At £220+ per month, Third Space costs approximately 3-4x more than a premium chain gym like Virgin Active (circa £120/month) and 8-10x more than a budget gym like PureGym (circa £25/month). However, members consistently argue that the membership effectively replaces separate Reformer Pilates classes (£15–£25 each), boutique HIIT sessions, yoga studio memberships, and spa visits. Several Fishbowl users calculate that the combined cost of these individual services elsewhere would exceed the Third Space membership fee.
Our Assessment: This is expensive. There is no way around that. But the value proposition depends on how you use it. Members who attend 4-5 times per week and take full advantage of classes, recovery facilities, and the café report feeling the membership pays for itself. Members who visit 1-2 times per week will struggle to justify the cost over more affordable alternatives.
What Members Actually Say: Review Analysis
Trustpilot (Clapham Junction Location)
Rating: Positive | Volume: 100+ reviews
The Clapham-specific Trustpilot reviews are overwhelmingly positive. Members praise the facilities, the cleanliness, the class quality, and the staff. One reviewer called it “the best investment to date” with “hotel vibes.” Another said it was “by far the best health and gym club in Clapham Junction.” The Reformer Pilates studio receives particular praise.
Trustpilot (Third Space Overall)
Rating: 4+ stars | Volume: 1,259 reviews
Across all locations, Third Space maintains a strong Trustpilot rating. Reviewers describe the staff as friendly and professional, and facilities as clean and well-maintained. Criticisms focus on overcrowding during peak hours at some locations and occasional customer service issues around billing and membership freezes.
Fishbowl
Tone: Nuanced and candid
Fishbowl — a professional networking platform — features candid discussions about whether Third Space justifies its cost. The consensus is broadly positive, with members praising the “beautifully designed” spaces, the quality of instructors, and the personal attention (staff learn your name). However, several users note that non-Canary Wharf locations are smaller, and a minority feel the classes don’t match the intensity of dedicated boutique studios.
Press Coverage
Sotheby’s International Realty named Third Space “one of London’s most exclusive gym groups” and highlighted the Clapham club’s Reformer Pilates studio, sauna, steam room, and Cowshed products.
Leisure Opportunities covered the club’s opening, noting the Grade II-listed setting and GM Sebastian James’s ambition to create “a beacon of wellness innovation.”
What Members Love Most (Positive Themes)
1. Immaculate Cleanliness This is mentioned more frequently than any other single quality. Members describe the gym as “spotlessly clean” at all times, with housekeeping staff visibly maintaining standards throughout the day.
2. Reformer Pilates Studio The 19-person studio is consistently cited as the club’s standout facility. Multiple members say the Reformer classes alone justify the membership cost, particularly given that external Reformer sessions typically cost £15–£25 per class.
3. Changing Room Experience Towels, Cowshed products, GHD tools, grooming essentials — members describe feeling genuinely pampered. One reviewer noted you could arrive with nothing and leave ready for a night out.
4. Natural Light and Architectural Beauty The Grade II-listed setting provides a gym environment that feels markedly different from typical underground or industrial-unit gyms. Natural light on the gym floor is a recurring positive in reviews.
5. Morning Busyness Levels Several members specifically praise the morning atmosphere — busy enough to feel energising, but not so crowded that equipment is unavailable.
6. Staff Professionalism and Warmth From concierge to trainers to housekeeping, every level of staff receives praise. Members note that regular attendance leads to staff learning your name — a personal touch that larger gyms rarely achieve.
7. Recovery Facilities Normatec compression boots, Theragun massagers, saunas, and steam rooms are included with membership — facilities that would cost significantly more as standalone services elsewhere.
Areas for Consideration (Constructive Feedback)
1. The Price There is no diplomatising this. At £220–£252 per month, Third Space is expensive by any standard. Members who visit frequently find it justifiable; those who don’t will feel the cost acutely. If you currently spend less than £100/month on fitness, this represents a significant increase.
2. Class Intensity Compared to Boutique Studios Some Fishbowl users note that HIIT, spinning, and circuit classes at Third Space are slightly less intense than at dedicated boutique studios like Barry’s or Psycle. This appears to reflect Third Space’s need to cater to a broader membership base, but it may disappoint members seeking maximum intensity.
3. Waitlist and Availability The Clapham Junction club has, at times, operated a waitlist for new members. Popular classes (particularly Reformer Pilates) can also fill quickly, though members report this has improved over time.
4. Social Atmosphere Several reviewers note that Third Space, like most large gyms, is not especially social. Members are described as “respectful” and “not pretentious,” but the environment prioritises focused training over community building.
5. Customer Service Inconsistencies (Brand-Wide) A minority of Trustpilot reviews across all locations mention frustrations with billing, membership freezes, and management responses. These appear to be isolated rather than systemic, but are worth noting.
Who Is Third Space Clapham Best For?
✅ Professionals who want a premium, all-in-one fitness experience — gym, classes, recovery, and spa under one roof
✅ Reformer Pilates enthusiasts — the studio is a standout facility
✅ Members who value cleanliness and aesthetics — the “hotel vibes” are genuine
✅ Those who currently pay for multiple fitness subscriptions — Third Space may consolidate costs
✅ Clapham Junction commuters — the two-minute walk from the station makes pre-work and post-work sessions practical
✅ People who are motivated by environment — natural light, beautiful architecture, and quality equipment
✅ Those seeking recovery facilities — sauna, steam, Normatec, and Theragun included
It may be less suitable for:
⚠️ Budget-conscious gym-goers (PureGym at £25/month offers basic facilities at a fraction of the cost)
⚠️ Those who visit fewer than 3 times per week (value diminishes quickly)
⚠️ Members seeking maximum-intensity boutique HIIT or spinning (dedicated studios may deliver more)
⚠️ Those who prioritise community and social atmosphere over facilities
How Third Space Compares to Nearby Gyms
| Feature | Third Space | Virgin Active Clapham | PureGym Clapham | Oncore Clapham |
|---|---|---|---|---|
| Monthly Cost | £220–£252 | ~£120 | ~£25 | ~£66.50/week |
| Pool | ❌ No | ✅ 17m indoor pool | ❌ No | ❌ No |
| Reformer Pilates | ✅ 19-person studio | ❌ No dedicated studio | ❌ No | ✅ Yes |
| Sauna & Steam | ✅ Both | ✅ Both + hydrotherapy | ❌ No | ❌ No |
| Recovery Tools | ✅ Normatec, Theragun | ❌ Limited | ❌ No | ❌ No |
| 24/7 Access | ❌ No | ❌ No | ✅ Yes | ❌ No |
| Towels Included | ✅ Yes | ✅ Yes | ❌ No | ❌ No |
| Café On-Site | ✅ Natural Fitness Food | ✅ Juice bar | ❌ No | ❌ No |
| No Joining Fee | ❌ £100 fee | ⚠️ Varies | ✅ No fee | ✅ No fee |
Verdict: Third Space wins on aesthetics, recovery facilities, Reformer Pilates, and changing room experience. Virgin Active offers a pool and hydrotherapy pool at a lower price point. PureGym is incomparably cheaper with 24/7 access but lacks any premium amenities. Oncore is the strongest boutique alternative for class-focused members.

London Reviews Verdict on Third Space Clapham Junction Review
Third Space Clapham Junction is, without question, one of the finest gym experiences available in South West London. The Grade II-listed setting is beautiful, the facilities are world-class, the cleanliness borders on obsessive, and the recovery offering — sauna, steam, Normatec, Theragun — adds genuine value that most competitors simply don’t provide.
But the price demands honest scrutiny. At £220+ per month, this is a luxury purchase. It works brilliantly for members who treat it as their primary wellness investment — replacing separate Pilates, yoga, HIIT, and spa subscriptions with a single, premium membership. It works less well for members who visit sporadically or who primarily use the gym floor without taking advantage of classes and recovery.
The Reformer Pilates studio is exceptional. The changing rooms are a genuine pleasure. The staff are warm and professional. And the building itself — history meeting high-performance fitness — creates an environment that makes you want to show up.
If you can afford it, and you’ll use it properly, Third Space Clapham Junction is very easy to recommend.
