These terms and conditions govern your use of the services provided by Green Oxygen Hyperbarics Limited ("we", "us", "our") at our studio in Marlow, Buckinghamshire. By booking a session with us, you agree to these terms.
Green Oxygen Hyperbarics Limited is a private wellness studio offering low-pressure hyperbaric oxygen therapy (HBOT) using a soft-shell chamber operating at 1.5 atmospheres absolute (ATA).
We are based at: Jubilee House, Third Avenue, Globe Park, Marlow, SL7 1EY. Phone: 07378 271411. Email: tommy@greenoxygenhbot.com.
Green Oxygen Hyperbarics Limited is a company registered in England and Wales, company number 16891588, with its registered office at the address above.
We are not medical professionals and HBOT as offered by us is not a medical treatment. Low-pressure HBOT in a soft-shell chamber at 1.5 ATA is provided as a complementary wellness therapy. It is not a substitute for medical advice, diagnosis, or treatment.
We make no claims that our sessions cure, treat, prevent, or alleviate any medical condition. We do not diagnose. We do not prescribe. If you have any health concerns, please consult your GP or a qualified medical practitioner before booking.
The decision to book is yours, and if you have any health concerns we encourage you to speak to your GP first. Before your first session we will also take you through our own health and safety screening (see section 3). Nothing in this section transfers responsibility to you for anything we get wrong.
Before your first session we will complete our health and safety screening with you and ask you to sign our informed consent and participation agreement. The screening is either a form you complete and sign online in your account on this website, which we ask you to do after you book, a paper form you complete at the studio, or a screening call in which a member of our staff reads you the same questions and records your answers. If you ever have trouble reaching the form in your account, we can email you a personal link to that same form instead. The informed consent and participation agreement is read and signed by you in person at the studio. Your screening record, your signed consent and participation agreement, and these terms all apply to every session; if they conflict, the screening record and the consent agreement prevail on health, safety, consent and liability for personal injury, and these terms prevail on everything else, including booking, payment and cancellation. The screening and consent documents cover topics including:
HBOT may not be suitable for everyone. There are some contraindications (such as untreated pneumothorax or certain lung conditions) where we will not be able to offer you a session. If we decide a session is not safe or appropriate for you - for example because of something in your screening form or consent agreement - we will refund any payment for that session in full.
If we require GP or consultant approval before your first session, no session will take place until we have received it.
Our sessions are for adults. You must be 18 or over to complete our screening, sign our consent and participation agreement, and use the chamber.
Sessions can be booked through our website or by phone. Your booked slot is 90 minutes. That covers your time in the chamber - around 60 minutes at full pressure, with roughly 5 minutes each side to pressurise and release - plus time on either end to arrive, settle in, talk through anything you need, and, on your first visit, complete your screening if you have not already done it online or over the phone with us, and sign your consent and participation agreement (see section 3). Please arrive at your booked time, not earlier; your slot already includes the time you need.
For bookings within 2 hours, please call us first on 07378 271411 to confirm availability.
We take online bookings up to 5 months ahead - call or text us on 07378 271411 and we will reserve sessions beyond that with you. We run one session per guest per day, so multiple sessions are always booked on separate days.
Payment is taken at the time of booking. Online, we accept cards through Stripe, our secure payment processor. In person at the studio we also accept card, as well as cash and bank transfer. Sessions bought in person are added to your account balance by us and work in exactly the same way as sessions bought online.
Card details are processed directly by Stripe and are never seen, stored, or held by us. Stripe is regulated by the UK Financial Conduct Authority.
Protocols. Most guests buy a protocol rather than a loose block of sessions. A protocol is a named course - a set number of sessions with a suggested weekly rhythm, built around a particular goal, running from ten sessions over a few weeks up to seventy-two over a quarter. A protocol is priced at the standard rate for the number of sessions it contains, so it costs the same as the equivalent package above. You can also design your own protocol of any length from 2 to 72 sessions, priced at those same rates, with the price shown to you before checkout. The rhythm a protocol suggests is a recommendation, not a condition of sale: you choose every session time yourself when you book.
Sessions expire 12 months after the date you buy them. This applies to everything you can buy from us - a single session, any package, any named protocol, and any protocol you design yourself - whatever its size and however you paid for it. Use them at whatever pace works for you within that time. Sessions that were already in your account before 4 September 2026 do not expire - they were bought under terms that carried no expiry, and we are not applying one to them.
All prices are in pounds sterling and are the total you pay. We are not VAT-registered, so no VAT is added.
7.1 Statutory cooling-off period (first 14 days)
Under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013, if you purchase a session or package online, you have the right to cancel within 14 days of purchase and receive a full refund for any unused sessions.
To exercise this right, contact us at tommy@greenoxygenhbot.com within 14 days of purchase. Refunds will be processed within 14 days of receiving your cancellation request, using the same payment method.
Important: By booking a session that takes place within this 14-day period, you are expressly requesting that we begin supplying the service during the cancellation period. If you then cancel, we will deduct the value of the sessions already provided to you (at the per-session rate of the package you bought) and refund the rest. The same applies if you cancel within 24 hours of a booked session or do not attend (no-show) - that session is marked as used and will not be included in your refund (see section 7.5).
7.2 Discretionary refunds (days 15-30)
Between day 15 and day 30 after purchase, you may request a refund for any unused sessions, provided you have not yet attended a session. Once you have attended your first session, your package is non-refundable. Any refund is calculated at the per-session rate of the package you purchased.
For example: on a 10-session pack at £550, if you have not used any sessions you may request a full refund of £550. If you have attended even one session, this discretionary window is closed.
7.3 After 30 days
After 30 days from purchase, sessions are non-refundable. You may use them at any time before they expire - 12 months from the date of purchase, or with no time limit if they were already in your account before 4 September 2026 - or contact us to transfer unused sessions to a friend or family member.
7.4 Exceptional circumstances
We may, at our reasonable discretion, issue refunds outside these standard terms on a case-by-case basis as a goodwill gesture. Any such refund does not form part of your statutory rights and does not set a precedent for future requests.
7.5 Late cancellations and no-shows
More than 24 hours before your session: The session returns to your balance and you can re-book it at any time.
Within 24 hours of your session, or no-shows: The session is marked as used and deducted from your balance. No card charge is made - we never auto-charge cards or take cancellation fees. If you have a genuine emergency, please call us on 07378 271411 - we will always try to help.
This 24-hour policy applies to every session you have bought, without exception - a single session, any package, any named protocol, and any protocol you designed yourself. It makes no difference how the session was bought or paid for: online by card, in person by card, cash or bank transfer, or drawn from a balance already on your account.
If you tell us before your session that you are unwell in a way that makes the chamber unsuitable that day (for example a cold, congestion or fever), the session is deferred and returned to your balance. It is never treated as a late cancellation.
7.6 Appointments subject to availability
We reserve the right to reschedule appointments in exceptional circumstances such as equipment maintenance, safety issues, or staff unavailability. In such cases we will provide as much notice as possible and either offer you the next available slot or credit the session back to your account, at your preference.
7.7 How to request a refund
Contact us at tommy@greenoxygenhbot.com with your order details. Approved refunds are processed via the original payment method and typically take 5-10 working days to appear in your account after approval.
Nothing in this section affects your statutory rights.
You agree to follow all instructions provided by our staff during your visit, including those relating to safety, equipment use, and chamber operation.
We reserve the right to refuse service or terminate a session at any time if we believe a guest poses a risk to themselves, our staff, our equipment, or other guests, including (without limitation) bringing an unapproved item into the chamber, being under the influence of alcohol or recreational drugs, behaving aggressively, or not following staff instructions.
If a session is refused, or has to be ended, because a guest has broken safety rules, that session is treated as used and is not refunded. If we decline a session because it is not safe or appropriate for you, your payment for it is refunded in full as set out in section 3.
Nothing in these terms excludes or limits our liability for death or personal injury caused by our negligence, fraud, or any liability that cannot be excluded or limited under English law.
Nothing in these terms affects your statutory rights as a consumer under the Consumer Rights Act 2015 - including your right to have services carried out with reasonable care and skill. These rights cannot be excluded or limited.
We are not responsible for harm we did not cause. This includes injury or loss to the extent it arises from information you did not give us or gave incorrectly, a change in your health you did not tell staff about, or your failure to follow staff instructions or the safety rules set out in your consent and participation agreement.
Subject to the first two paragraphs of this section, and excluding any claim for death or personal injury, our total liability to you is limited to the amount you have paid for the sessions concerned. We are not responsible for loss of or damage to your belongings, or for indirect losses such as lost earnings or missed arrangements.
Low-pressure HBOT has a well-established safety profile for healthy individuals. As with any therapy there are some normal, mild effects, most often a gentle sensation of pressure in the ears while the chamber pressurises, which eases by equalising your ears as staff will show you - swallowing or yawning often works, or gently blowing against a pinched nose. Before your first session, your consent and participation agreement will take you through these and other effects so that you can make an informed decision to take part. This does not reduce our responsibility for any loss or injury caused by our negligence.
You are responsible for keeping your account password confidential and for all activity that occurs under your account. Notify us immediately if you suspect unauthorised access.
You can delete your account at any time from the My Account page or by emailing us. Some records may be retained as required by HMRC for tax purposes (see our Privacy Policy).
The Green Oxygen Hyperbarics name, logo, website content, photographs, and graphics are our property and may not be reproduced, copied, or used without our written permission.
We may update these terms where we have a valid reason - legal, regulatory, safety or operational. Material changes will be notified to registered users by email. No change will take away sessions you have already paid for, and if a material change is to your disadvantage you may reject it by cancelling your remaining unused sessions for a refund at the per-session rate you paid, whether or not the 30-day window in section 7 has passed. Continued use after we have notified you constitutes acceptance.
These terms are governed by the laws of England and Wales. Any disputes will be resolved in the courts of England and Wales.
If you have questions about these terms, please contact us at tommy@greenoxygenhbot.com or call 07378 271411.
