Hyperbaric oxygen therapy

Is a non-invasive, painless therapy used to increase the oxygen concentration levels within your body. To increase the body’s volume of oxygen a combination of pressure created by the hyperbaric chamber and higher oxygen concentration (typically 90-95% compared to ambient air of 21%) means that after a single session you can increase your body’s oxygen levels in the bloodstream of upwards of 1000%

Will Collier

Harlequins

Playing a contact sport like rugby means I’ve tried every mode of recovery to get myself feeling good.

I can honestly say nothing compares to HBOT.

As soon as I get out of the chamber I feel far less fatigued, more alert and have a greater clarity of vision.

I also strongly believe in the long term effects treatment can have on crucial aspects like brain health.

Laurie Canter

Professional Golfer

Recently hired a chamber for a 2 week period. Russell and the team were superb and couldn’t do enough to help, before and during the process.I found the treatment really helpful in reducing recovery time and helping my training. Will definitely be a returning customer.

James Chisholm

Harlequins

As a rugby player being able to recover quickly is very important for me. I’ve found hbot incredibly helpful for both my physical and mental recovery.

Russell and the team are great and genuinely care about their work and my recovery.

Jack Richardson

Professional Polo Player

I rented a chamber for 4 months to help with my Arthritis whilst competing in professional sport. The chamber reduced my pain and discomfort by 40% which made a massive difference. My girlfriend also used it to help with her asthma whilst running and felt so much more confident and needed to use her inhaler a lot less. The team at Simply Oxygen were very easy to deal with and super helpful, i would definitely recommend them to anyone.

Stephan Lewies

Harlequins

HBOT has benefitted me in more than one way.

As a player struggling with Asthma I’ve reaped the rewards of using HBOT before games and I’ve felt a significant improvement in performance. The recovery benefits are unbelievable.

I’ll recommend HBOT to anyone that is serious about their health and performance.

Raj Sinnathuray

NHS consultant

I’m a 58-year-old NHS medical consultant. After living with type 2 diabetes since 2004, I developed a diabetic foot ulcer in 2023 that failed to heal despite 21 months of NHS treatment, including input from specialist diabetic foot teams and a large London teaching hospital. Nothing worked — in fact, some treatments made the ulcer worse.
In 2025, I turned to hyperbaric oxygen therapy as a last resort. Under Russell’s guidance, I underwent intensive treatment—4 to 5 sessions per week, with oxygen directed specifically onto the ulcer. Within 4 weeks, there were visible improvements confirmed by my hospital podiatrist. By the second month, the ulcer had gone from deep to superficial. By the end of the third month, it had completely healed.
This therapy achieved what conventional NHS treatments could not. I want other diabetics to know that even when it feels like you’ve run out of options, hyperbaric oxygen therapy may offer real hope.
