Third Space London Reviews 

Gym and facilities are in good condition, but I wouldn’t call it a luxury gym due to the amount of members they have accepted at the same time. At certain times gym is overcrowded and you have to wait for certain machines or spots to be available (which is the feeling of a cheaper brand gym) and classes are always getting also too overcrowded to the point that sometimes there is no proper space to even position yourself in the class with your dumbbells etc… so many times I had to train by the exit door which is again not good enough for a luxury gym. On the top of that be carefully with their T&Cs on the leaving notice. They tell you “full calendar month” for a notice, but it turns out they are misleading you by not mentioning very clearly that the calendar month only starts from the 1st of each month, meaning if you’ve given the notice on the 2nd of any given month then you will have to wait for 2 months to leave the membership. This is a very cheap tricky approach which I didn’t appreciate. Supposedly there are so many people waiting to become members so I don’t understand the need to be working with this misleading approach. It’s not about the money, but all about the approach they have! So the shell of the business is trying to be luxury, but the soul of it is a cheap and misleading!

I have never really enjoyed going to the gym before as I felt intimidated by the equipment and people on the gym floor. Third Space Richmond is different - it feels inclusive, never feels too busy and there are so many classes that are great. I only wish I had more time to go!

I absolutely love the Thirdspace gyms, I have been a member for a while and they keep improving even when I don’t think things can get better. Top of the range equipment, incredible instructors and classes and really great atmosphere and aesthetics

The house keepers my favourite people in the gym. Fernando especially never walks past without greeting me. Goes along way. Jesus also is another not sure of other names. The staff at the cafe are also lovely. Kimberly my favourite new member of staff there

I really appreciate when small things could be better , the staff take feedback seriously. There is really quick follow up, for example in relation to some members and guests ignoring the no phones in the sauna. It really makes a difference from your voice being lost in a mega organisation. I sometimes go to other third spaces but feel that most lack the personal touch of Marylebone. I always leave with a contented bounce in my step.

I love it! Making me excited about exercise and wellness again!

Third Space is such a wonderful and fitting addition to Richmond.

I have thoroughly enjoyed being a member for a whole year - the classes, instructors and facilities are great.

Something that I really like about the gym is that they have some excellent classes during the off peak periods. I absolutely love classes with Paddy & Karen, both are extremely pleasant and motivating.

Third Space are definitely doing things right and I’m glad I get to experience this as a member.

The best gym and the best concierge team!!!

I’ve had such a great experience at this gym. it really stands out among London gyms. The recent extension has made a huge difference, with plenty of new space and a fantastic range of modern machines, so it never feels overcrowded even during busy times.

What really makes this place special, though, is the team. Molly, Anna, Georgina, Jasmine, Stef, Rob, Shaunley, and Francis are all incredibly friendly, approachable, and genuinely supportive. They create such a welcoming atmosphere and are always happy to help, whether you’re new or a regular.

Overall, it’s a well-equipped, well-run gym with a great community feel. Highly recommend!

I got a very nice, relaxing and soothing head massage. The therapist was professional and used her hands exactly how she supposed to.
The place is clean and it smells nice. Staff is polite and helpful.

Essential to join if you want to make a positive impact on your health and lifestyle.
I used various third space gyms around London but found that the city branch on marks lane was my second home.
What sets it apart from the rest.
All the staff that work there made the place feel welcoming, relaxed and comfortable to train there.
Soho and canary wharf is only 3 to 4 stars but the city branch was 5+
Lucy Shiplee was a Rolls Royce PT… she was relentless in seeing that my health and wellbeing improved vastly over the 3 months I trained there, also she helped my swimming technique too as I’m a PADI diving instructor
Other instructors were helpful too (Dan and Charlie)
The gym itself is first class, it’s expensive but if you use it regularly it’s worth it. Food is pricey thou..
The place was never really full up when I trained there and has far better etiquette than the other gyms I used.
Great swimming pool and sauna and also has a cold pool…
For me the greatest asset in a place I visit is is the environment and the city branch certainly had a very pleasant one. 👍

Been a member for 5 years, and have seen the business develop - from a single soho location to now never being further than 10 mins from a location today. Thirdspace is a great option if you want to take your health and wellness seriously, be part of a community and be surrounded by like minded individuals!

Great range of classes, friendly and experienced instructors and a lovely pool and chill out space

This gym is like a luxury Chocolate box, you have an assortment of classes and you cant stop trying them all out.
Very varied and exciting. My highlights:
Saturday with Sally and her running social club, which is fun and chatty
Then Tuesday/Thursdays we have Afterburner with Paddy and his wild tunes, always gets you moving.
So nice to recover with Trevor on the reformer.
Cant thank you enough, Team Third Space Richmond!

This place is honestly amazing, I don't even know how to put it into words. Everything about it is top quality. The cleanliness is outstanding and you can really tell they take great care pf the space, the variety of the classes on offer is excellent, with something for everyone every single hour. The facilities are simply top-notch.

What really makes the difference is the staff, they are all so friendly, professional and welcoming which creates such a great atmosphere every time I go. ( especially the Pilates instructors - Janet and Kayla)

Overall, this is by far one of the best gyms ive ever experienced. Highly recommend,

An exceptional gym, highly recommend! The gym itself is well thought through in terms of layout and decor. There are plenty of classes to chose from, even if on the waitlist you tend to get a spot. The trainers and all staff are very welcoming and highly skilled. In particular Kayla for her creativity and confidence building classes, Jocelene - for her excellent cues and tough workouts, Thalia - For her calming voice and beautifully thought out workshops and Dylan (PT, Injury Management) - Strong understanding of human movement, how to move properly, helping you build habits that benefit you in the long run.

Excellent classes, great instructors.

Always a great welcome from the front desk at Third Space Richmond!

Absolutely love the gym and the quality of the classes.

The swimming pool is the icing on the cake!

I’ve had such a positive experience with the team at Third Space Marylebone since moving from Canary Wharf in 2024. Recently, it has been especially lovely getting to know some of the newer team members - every visit leaves me with a smile on my face, and it’s always something I really look forward to. The team are consistently motivating and supportive, making the whole experience feel truly worthwhile, and I’d like to especially thank Nathan, Ben, and Noemie who always so friendly, welcoming, and genuinely pleasant to be around.
