London Hypnotherapy for long lasting change

Solution focused
clinical hypnotherapy

Welcome to Deep Dive Therapy. Over the past ten years, it has been a real honour and pleasure to help hundreds of people see long lasting and real change in just a few sessions.


Would you like to stop an unwanted habit or behaviour?
Is it time to find strategies and overcome a specific stress, anxiety, fear or emotional issue?
Are you looking to gain more self confidence at work, in your personal life, or increase motivation?


Deep Dive sessions aim to help you feel centred again. Gain confidence and gain skills to live a life of joy, purpose and fulfilment. Why settle with just getting by?


Are you at a crossroads or looking to find clarity about aspects of your life?
Do you feel slowed down by intrusive or unwanted feelings, habits or thoughts?
Is your happiness affected by current challenges or by unresolved aspects of your past?


Life is too short to live as if ‘driving with the handbrake on’. Why not take a step forward today. Very soon you will be heading again to living the life you truly want and deserve.


I use a combination of solution-focused clinical hypnotherapy, neuro-linguistic programming (NLP),
aspects of cognitive behavioural therapy (CBT), as well as mindfulness based cognitive therapy and
traditional coaching strategies.


The Deep Dive approach is unique. Sessions often feel more like a stimulating and interactive workshop, without you being ‘on the spot’, feeling you have to talk non-stop. Our work together will be focussed, with a highly professional, yet flexible and calming approach to change.


Please read some testimonials from former clients. These are people, just like you, whom I have helped and have enjoyed seeing positive results.


I invite all perspective clients to book an initial phone consultation, under no obligation. I see clients in central London and in North West London. Many clients come for two to four sessions. Sessions last up to two hours and cost £200.



London Hypnotherapist Jason Demant has appeared in the media, both in print and online:




Stephanie, East London

I had several sessions with Jason at the beginning of lockdown to help with my anxiety and anger management. Before seeing Jason, I would be short tempered and very reactive in situations, but after a few sessions I started to understand these feelings and emotions more. He really pulls apart situations and makes you dig deep into why you’re feeling the way you do. He also provides practical advice and techniques that have really benefited me over time.


James, Essex

I went to Jason after trying for years to break some bad habits.
As well as listening and encouraging me, he gently taught me to think differently about these habits and helped me get more in control of them.
I learned a lot from Jason, and would certainly recommend seeing him.


Kiesha Edwards, Essex 

I found Jason to be tremendously helpful! I was struggling with an anxiety that had manifested as a phobia and after one session of hypnotherapy found myself feeling unburdened by this problem altogether. Would highly recommend and would certainly return in the future if in distress. Thank you


In the video Jason delves into why he is equipped to help clients work through challenges with Deep Dive Therapy.

How does Deep Dive Therapy Work?

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 in London. 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.

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. Session in King's Corss, London or online.

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.

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. Sessions are in person in King's Corss, London or online. 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.

Session last up to two hours and are £200. 50 minute sessions are £100. Cocaine addiction sessions are £110 with a lower rate for a block of sessions.

Life coaching fees vary according to package. The standard smoking cessation programme is £295.

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.

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.

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.

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. Sessions are in person in King's Cross, London or online.
