Jason Demant

Therapist in London

Jason has worked as a clinical hypnotherapist for ten years. He sees clients in London and also works as an online therapist.


Before moving into therapy work, Jason’s career was centred in teaching, mentoring and youth work. It was following working for a Samaritans style hotline for university students, that Jason found his real passion in therapy work. He enjoyed helping people, often in great emotional distress, get back to a place of calm and balance.


Jason has volunteered and worked for three of London’s hospices. During this hospice work, Jason managed teams and provided informal counselling for patients and family members towards the end of life and informal bereavement support. Alongside seeing patients, Jason provided pastoral support for hospice staff, supporting them to gain resilience and avoid burn out.


Over the past decades, Jason has had his own personal experience of addiction, anxiety, bereavement and had questions about spiritual beliefs, life direction and purpose. The wisdom of varied life experiences and challenges all help Jason listen to clients without judgement. Working as a therapist in London, he strives to empathise with people from backgrounds very different from his own. Jason will not jump to assumptions but rather allows clients to tell their own story and at their own pace.


Clients gain from Jason’s broad knowledge of emotions and how our thought patterns and behaviours interact with each other. Jason uses his deep understanding of the human condition and professional experience to support the changes people want to achieve for themselves. Jason also holds a postgraduate management qualification from the London School of Economics and Political Science (University of London).

Angela, Shepherd's Bush London

I’d spent years living with uncomfortable symptoms when a gastroenterologist suggested seeing Jason to try an alternative approach. He helped me to uncover thinking patterns and behaviours that were contributing to these issues. Jason also supplied me with recordings and suggested techniques to reduce my levels of anxiety and resulting symptoms.


Zack, Hackney - London Fire Service

Jason is extremely easy to talk to and committed to working through any issues. His hypnotherapy has given me a spring in my step in overcoming drug addiction and would gladly recommend him to anyone.


Aaron, London

Jason really helped me put my goals and ambitions into perspective and gave me some extremely useful tools for putting the theory into practice. I'd recommend Jason's services to anyone who wants to make a positive change in their lives - be it big or small. Keep up the fantastic work!

    How does Deep Dive Therapy Work?

    How is Deep Dive Therapy different?

    Deep Dive Therapy is a personal change concept not offered by anyone else. I am not wedded to one form of therapy and sessions draw in a number of approaches, including neuro-linguistic programming (NLP), clinical hypnotherapy and aspects of cognitive behavioural therapy (CBT). I also frequently use life coaching and mindfulness-based approaches.

    I am flexible and open, using my intuition and experience to decide what intervention would be the most useful for a client at the present moment.

    With kindness and compassion, we dive in quickly on what is really bubbling under the surface for you. Addressing what is really going on, but at your pace and in line with what you are happy to do.

    Yes, there are many hypnotherapists, NLP practitioners and life coaches. However, I bring a very fresh and effective way of working. I call my technique ‘Deep Dive’ since we get to the core and underlying issues quickly. I don’t waste your time on anything you don’t need.

    How many sessions will I need?

    For most challenges sessions last up to two hours. You will see that for some treatments sessions are shorter. For example, life coaching sessions, following an initial two hour session, are 50 minutes in duration.

    For some phobias, one session is sufficient. For many addictive patterns, between two and four sessions are beneficial. Sessions can be weekly or spaced out. My quit smoking programme is for two sessions, one session of just over 90 minutes, with a second ‘quit session’ of 50 minutes. Life coaching packages vary in session number.

    I have found that sessions of up to two hours in duration can ensure we really do dive deeply into the issues at hand. In a shorter one hour session, it can happen that we have to stop just as we were getting to the real issues. Things get left on a ‘cliff-hanger’. This is frustrating and may delay change and progress. We have to restart again a week later, rather than continuing and building on the positive momentum just created.

    What is the booking process?

    The process is straightforward. Simply get in touch today using the enquiry form and we will arrange a time for your first session. I also offer a free, no-obligation, initial phone consultation. Use your free consultation to ask any questions (no matter how small) and decide of I am the right therapist for you. Once we have a date in the diary, I will send you a brief background questionnaire to fill-in as well as a document which outlines terms and conditions around how sessions are run.

    How much are session fees?

    Session last up to two hours and are £200. 50 minute sessions are £100. Life coaching fees vary according to package. The standard smoking cessation programme is £245.

    Can I pay in instalments?

    I do understand that sessions are an investment and paying upfront for sessions can be difficult for many people. For individually booked sessions, you will need to pay in full before or at your session.

    If you book a package of sessions, you can pay in instalments. However, in general, you will pay at least £200 before your first session. The remainder will normally be paid, in full, before your last package session. If you require a longer period to pay, please be in touch to discuss your needs.

    We will establish very clearly when and how much your payment plan is. This will be by email or on paper so that our agreement is recorded.


    When you book a session it is for up to two hours. This means that I will set aside this amount of time for you and I will be totally available for that time. You have paid for my time. If you come late, no matter what the reason, I cannot make any promises that we will be able to go beyond your agreed session time. I do not give refunds when you are late.

    Sometimes coming late is unavoidable, should there be train delays, traffic or unavoidable holdups. However, if you anticipate there could be delays, ensure you leave enough time. It's better to be a few minutes early than a few minutes late.
    If you do need to cancel a session, please be aware that your booking is subject to a rigid 48-hour cancellation/rearrangement policy. If I do not receive a minimum of 48 hours notice of cancellation or rearrangement, I will still charge for the appointment in full. If a £1 pre-authorisation payment has been taken on your debit or credit card for the first session, I reserve the right to use these card details to charge for the appointment via PayPal. If I have not taken a pre-authorisation, I will raise an invoice and email it accordingly.

    Terms and conditions of how sessions are run will be set out in your ‘Working Agreement’ document. This document you will receive by email after you book your first session. I am always happy to discuss this contract and make changes to suit your needs.

    If you have booked a two-session smoking cessation programme and attended one session, there is no refund for the second session. You will, however, have that session as a 50-minute session ‘credit’, which you can use for a future session, or gift to a friend to use in your place.

    If you have paid for a package of sessions and in so doing received a discount for a block of sessions, cancelling will mean you are no longer entitled to the discount rate. Any sessions attended will revert to the regular session fee of £100 an hour/ 50 minutes. A refund will be based on that rate.


    No client financial information, including credit or debit card details, is stored by Deep Dive Therapy. We retain client email addresses for the purposes of communicating regarding a client’s sessions or for marketing purposes. We do not share your information with any third party or partner. As a therapist, I make brief notes, for myself, to summarise sessions. These notes are kept locked and secure. Only I have access to them. Notes are destroyed when no longer needed. Notes are stored for seven years due to United Kingdom legal requirements.

    Sessions are confidential. I will not share anything you say with anyone else. I hope you will feel free to talk openly and sessions can feel like a haven, a safe space to be honest.

    However, there are two scenarios in which I may share information about you with someone else. The first is if I should consult a colleague or supervisor to ask their advice about how best to help you. In this situation, I will not use your name and will change some details to ensure your identity is kept confidential.

    The other scenarios which are relevant are if I feel that you may harm yourself or others or if you talk (boast) about committing a serious crime. 
    Unless it is an emergency, I will always discuss with you before speaking to someone else about you. You should feel confident about how sessions work and not feel any need to hold back on anything you wish to say. Please ask me any questions about this, so it is clear.


    As much as I would love to 100% guarantee you success, sadly I cannot do so.

    Many think that hypnotherapy, in particular, is like a magic wand. Popular thinking is that a client doesn’t need to do anything actively and the hypnotherapist will miraculously remove whatever problems a person has. I wish it was that simple. You will need to do some work too. All the great changes you wish to see must be carried out by you. You are responsible for your decisions, habits, choices and mindset.

    What I can guarantee is that I will work my hardest for you. I promise to provide you with the best tools I have, to ensure you have the greatest chances to succeed. In return, if you have strong determination and are prepared to roll your selves up and commit to the ‘work’, I do hope you will see some wonderful changes.

    I’m passionate about what I do. I really get a great deal of joy and satisfaction seeing people receive results far and beyond what they expected. I hope this will be the case for you also.

    What Is hypnosis and hypnotherapy

    Hypnotherapy is the use of hypnosis for emotional and behavioural change work. Hypnosis is really the guiding of someone into a relaxed state. During hypnosis, your eyes are closed and you are relaxed. However, you are able to hear everything that is going on. You do not lose control and can open your eyes if there is a need to do so. It is a myth that you can be tricked into doing something you would object to. Clinical hypnotherapy uses hypnosis to guide you through some helpful and powerful visualisations. Hypnotherapy is relaxing and addresses subconscious patterns of thought so that you can shift mood, thoughts and ideas.

    Can everyone be hypnotised?

    In general, most people can experience hypnosis. In my experience, it is rare that someone is unable to go into a ‘trance’. However, if you find it very hard to relax or find it difficult to trust other people, it is still possible but may just be harder work for your therapist. It is not advised to undergo hypnotherapy if you have recently drunk alcohol or taken drugs or strong medication. Check before your session if you have any concerns about your suitability.

    What is the difference between Life Coaching and other Deep Dive Therapy sessions?

    Many clients find that between one and four Deep Dive therapy sessions are sufficient to make some wonderful changes. We get to the underlying issues quickly and set you on a positive course. However, life coaching is about longer-term support over a few months. Coaching is ideal for someone navigating ongoing work projects and relationships, wishing to create change, or perhaps get used to new life circumstances.

    In other words, life coaching or executive coaching helps you succeed in challenging changing or ongoing situations. So, for example, a person suffering from high anxiety may have just a few sessions. However, someone going through a divorce or navigating running a new business may need more ongoing support.
