Having visited several hyperbaric oxygen therapy clinics across London, I can say with confidence that this one stands head and shoulders above the rest. From the moment I walked through the door, the atmosphere was warm, welcoming and reassuring. The entire team was attentive, professional and genuinely caring — they clearly take pride in making every patient feel at ease. Dr. Nur was outstanding. Her assessment was thorough, considered and confidence-inspiring. You immediately feel you’re in capable, expert hands. I’ll be honest — I am quite claustrophobic, and I was apprehensive about the treatment. But the staff handled my concerns with such patience and expertise that the whole session turned out to be surprisingly relaxing. A real testament to how well they manage their patients’ comfort. Most importantly, my results have been superb. I couldn’t be more pleased with the outcome. If you’re considering hyperbaric oxygen therapy in London, look no further. This clinic truly sets the gold standard. I won’t be going anywhere else. > > [Read the full review in Google ↗](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2xWSmFrUkNTbmRMU2tsTmJUbG9aVjlmVUZoT00wRRAB!2m1!1s0x0:0xc3bc43a8cc867b51!3m1!1s2@1:CAIQACodChtycF9oOlVJakRCSndLSklNbTloZV9fUFhOM0E%7C%7C "Read the full testimony on Google Reviews") > 4 months ago > > I am a physiotherapist by profession, and hyperbaric oxygen therapy had been on my radar for some time. I was familiar with its benefits, including improved oxygen delivery to tissues, anti-inflammatory effects, stem cell mobilisation, and support for repair and regeneration. I wanted to experience it personally and also understand it better as a potential option to refer my own patients. I chose NUMA Hyperbaric Oxygen Clinic because it stands out as a leading medical hyperbaric clinic in London, operating under full medical governance led by Dr Nur Ozyilmaz, a former NHS consultant with extensive clinical experience. > > I had a truly exceptional experience at NUMA, from start to finish. > > From the moment I arrived, everything felt calm, welcoming, and beautifully organised. The clinic itself is immaculate, elegant, and thoughtfully designed. It feels professional yet warm, with a very reassuring atmosphere that immediately puts you at ease. > > The staff are lovely. Every member of the team was kind and genuinely attentive at every step. Nothing felt rushed or impersonal. They took the time to explain each part of the process and checked in throughout the sessions, which made the whole experience feel safe and very well cared for. > > My consultation with Dr Nur was excellent. It was thorough, clear, and extremely informative, and my treatment was clearly tailored to my medical background. What really stood out is that this is not a copy-and-paste approach. Each treatment plan is individualised, based on medical history and current clinical research, and delivered under full medical supervision. > > The hyperbaric chamber was very comfortable and clearly medical-grade, with proper BIBS masks, which gave me real confidence in the quality and safety of the treatment. Despite bringing a book, I found the sessions incredibly relaxing and ended up sleeping through most of them. > > Overall, the quality of care at NUMA is exceptional. It combines clinical excellence with a genuinely human, compassionate approach.

It is unfortunate that HBOT remains under-recognised and under-used in the UK, despite its established role in many healthcare systems in other countries. > > I completed a course of HBOT at NUMA Hyperbaric Oxygen Clinic, and the experience was excellent. I found the first part of the initial session slightly daunting, which I think is quite normal for anyone new to hyperbaric treatment. However, the team were immediately reassuring. The staff were kind, attentive, and genuinely supportive, which helped me relax and enjoy the rest of the course. > > The clinic itself is beautifully designed and maintained to a very high standard. It is immaculately clean, calm, and has a peaceful, relaxing atmosphere. From the initial consultation through to the final session, Dr Nur and her team were consistently attentive, professional, and thoughtful in their approach. > > I would confidently recommend NUMA as a medically led hyperbaric clinic in London for anyone exploring HBOT in a safe setting, with proper medical oversight and a genuinely caring team. > > [Read the full review in Google ↗](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2xoa1ZYbFJkbkpDYUd4eFFuTTFPRXBaYUhWdGMwRRAB!2m1!1s0x0:0xc3bc43a8cc867b51!3m1!1s2@1:CAIQACodChtycF9oOlhkVXlRdnJCaGxxQnM1OEpZaHVtc0E%7C%7C "Read the full testimony on Google Reviews") > about 2 months ago > > Fantastic clinic with the kindest and most accommodating staff.

The facilities are spotless and maintained to an exceptionally high standard, which immediately inspires confidence. The staff are genuinely kind, attentive and highly professional. They take the time to explain everything clearly, ensure patients feel at ease, and provide a very reassuring environment throughout. My son attended several hyperbaric oxygen therapy sessions here as part of his post-operative recovery, and everything was handled smoothly and with great care. Many thanks to the whole team for the quality of the service and support. I would not hesitate to recommend this clinic.

From the moment we arrived, everyone was so kind, welcoming and genuinely lovely. They made my two daughters feel completely at ease and took the time to explain everything clearly, with so much care and reassurance. > > My daughters are 17 and 14, both MMA fighters, world champions and European champions, so recovery and looking after their bodies is incredibly important to us. They visited Numa to support their recovery from sport, and the whole experience was calm, professional and really positive from start to finish. > > What stood out most was how passionate and caring the staff were. They are truly some of the loveliest people we have met, and you can tell they genuinely believe in what they are doing and the benefits it can bring. We also really believe in the work they are doing, and how hyperbaric oxygen therapy can help people in so many different ways. > > As the girls continue to grow within their sport, especially with the physical demands of fighting and the possibility of head contact in the future, we can absolutely see how Numa could be a huge support for them over the years. We would definitely use them again and would highly recommend Numa to anyone looking for a caring, knowledgeable and professional team. > > Thank you so much to everyone at Numa for such a lovely experience.
