Current Fees

Initial general psychiatric assessment

  • Up to 1.5 hours – £560
  • The fee may differ should there be a pre-arranged fixed rate with your insurance company. You will be responsible for any insurance company excesses.

ADHD assessment

  • Please note Vanderbilt parent,  teacher and separate school questionnaire must be completed prior to the assessment and depending on your child’s age a self-report questionnaire.  If you did not receive these blank forms when booking the appointment, please e-mail to request them.
  • If diagnosed and medication prescribed, included in the initial ADHD assessment charge of £900 will be email liaison between you and Dr van Zwanenberg regarding benefits, side effects and dose changes required and further brief GP update letters between the initial assessment date and the next review date. The next review will occur within 3 months of the initial assessment for 30 minutes at a charge of £185. If there are no ongoing concerns, 30 minute review appointments will then be 6 monthly at a cost of £185, whilst the young person remains on medication.
  • There is a separate charge by the Pharmacy for medication, if prescribed.
  • A detailed diagnostic report will follow the initial assessment along with a short letter for the young person’s educational setting. This short letter will be sent to the young person/family to give who they feel is appropriate.
  • GP update letters will be sent following each review appointment and is included in the review fee.

Autism assessment

  • An initial general psychiatric assessment is the first appointment (up to 1.5 hours) if you wish for other mental health conditions to be considered prior to the autism spectrum disorder assessment £560.
  • If just an autism diagnostic assessment is required only the following two parts need to take place, (Dr van Zwanenberg may request you and the young person’s educational setting, (if you consent to that), complete some questionnaires prior to the assessment):
    • Part 1: An Autism Diagnostic Observation Schedule – ADOS, completed by another clinician with the young person, probably on a separate day. Please note the ADOS costs are charged directly by the clinician and separate to Dr van Zwanenberg’ charges. Please ask for up to date costs.
    • Unless agreed otherwise in advance, we aim for the ADOS to be completed first and the report to be available to Dr van Zwanenberg in time for the developmental history appointment so clarity can be given regarding whether a diagnosis is appropriate at end of Dr van Zwanenberg’s appointment.
    • Part 2: An online appointment with Dr van Zwanenberg on a separate day from the ADOS will be a detailed developmental history with Dr van Zwanenberg: £900 (approx. 1.5 hours with parents only). A detailed report will follow Dr van Zwanenberg’s appointment with the ADOS and developmental history detailed in this report. There will be an additional short letter for the young person’s educational setting. This short letter will be sent to the young person/family to give to who they feel is appropriate rather than sent directly to school.

Combined ASD and ADHD assessment

  • Part 1: Autism Diagnostic Observation Schedule – ADOS, completed by another clinician with the young person. Please note the ADOS costs are charged directly by the clinician and separate to Dr van Zwanenberg’ charges. Please ask for up to date costs.
  • Part 2: A detailed history with Dr van Zwanenberg; this is online and on a separate day from the ADOS. Part of the assessment will be with parents only and part of the assessment with parents and the young person (and the young person is offered time on their own too if they wish to have this). A detailed report will follow with the ADHD assessment, ADOS and developmental history and whether a young person meets criteria for diagnose. An additional short letter for the young person’s educational setting will be provided too. This short letter will be sent to the young person/family to give to who they feel is appropriate rather than being sent directly to the educational setting £1200.

Follow up

  • Per half hour of follow up for any diagnosis: £185 for the 30 minutes and pro rata thereafter. If you believe you need a longer follow up than 30 minutes, please ask to book a longer slot.


  • Repeat prescriptions that require posting will be charged at £12 to cover postage and administration costs, (those given in a clinic review will be free); Dr van Zwanenberg usually uses an online pharmacy cloudrx for prescriptions which she can detail to you further at the appointment.
  • Controlled drug repeat prescriptions will be charged at £20 unless requested at a review appointment (this is due to all the paperwork involved in issuing a controlled prescription).

Additional phone calls

  • Additional telephone calls requested outside of the treatment plans made in clinic, (which may involve a free planned telephone call), will be charged at £30 for the first 15 minutes and £50 per 15 minutes thereafter.

Extra letters

  • New letters requested outside of clinic appointments will be charged at £30 for a short letter eg for DLA, disability student allowance, exam boards and £50 for longer letters. Reports for example for an EHCP application will be priced individually on request.

Please note payment is required prior to the day of consultation. You will be sent an invoice in advance of the appointment by Dr van Zwanenberg’s automatic invoicing system via Xero accounting.

If you have private medical insurance, please provide confirmation of your membership details and authorisation code prior to your appointment. It is your responsibility to confirm with your insurer in advance that your care is covered by your insurance policy.

If payment is to be made through your private medical insurance and an excess is due or the insurance company decline to make payment, you remain liable for the payment. You can find out whether an excess is due by speaking to your insurance company or checking your policy details.

Please note: Insurance companies do not pay the excess due direct to Dr van Zwanenberg when settling the invoice for the consultation fees. Any excess payment due must be made by yourselves to Dr van Zwanenberg before or on the day of the consultation please.

* The fee may differ should there be a pre-arranged fixed rate with your insurance company. You will be responsible for any insurance company excesses.

Fees will be reviewed periodically so please ensure you are aware of current charges.

Cancellation Policy

I will try to accommodate requests to reschedule appointments wherever possible but costs are incurred when changes are made at short notice. I therefore require you to give at least 2 clear working day’s notice via or via the administration team at the Priory Wellbeing Centre in Oxford if you wish to cancel or change your appointment otherwise you will be charged the full fee for the missed appointment.

Please note that most health insurance companies will not generally cover the cancellation fee and you will be liable for this.

Below are written comments from feedback from recent young people who have been seen by her in her clinic:

Thank you ever so much for a very thorough assessment.

Dr Hayley is phenomenal – she has transformed our daughters life and we are grateful every day that we found Dr Hayley and got the help we so desperately needed.

Dr Hayley she is a amazing person, very caring, patient and helpful
So happy my son is finally getting the help he needs to free himself of a life of anxiety. Thank you.
Very kind and knowledgeable
Hayley was wonderful. She engaged with my son beautifully despite his almost constant hyperactivity and chattiness during the appointment! She has a lovely warm approach while remaining very professional and highly knowledgable. I wouldn’t hesitate to recommend her.
Dr H has made a lasting improvement on both my daughters’ states of mind and their approach and outlook to life. I can not rate her services highly enough.
The doctor was really personable and helped to make my son feel comfortable, she asked great questions to elicit information to help the diagnosis and was very good at listening to our feedback

Very happy with Dr Hayley. She She’s very kind and makes us feel at ease within the session. listens carefully to problem and tries to recommend a right solution. She’s very prompt in replying emails or in event of asking for prescription, which itself has made me feeling better in the stressful situations we have been experiencing. I am very happy with her and would recommend to others. Thank you Dr Hayley.🙏🏼🌸

We feel blessed that Dr van Zwanenberg was available when my daughter was referred. It was a relief for my daughter to be understood and feel that there was hope for getting better. Dr van Zwanenberg has been endlessly kind and provided the expertise needed so that we felt completely supported. Although we have not had to use it a lot she has been available for advice in between appointments, which again adds to our feeling of being well supported. We would wholeheartedly recommend her and know she would do the best for anyone who came to see her.
Lovely Dr who was there to listen and help anyway possible. Full in detail and good natured with myself and my son. Got a lot from it and finally felt we were listened too. Lots of advice and next steps to follow.
Dr van Zwanenburg put my 10 year old at ease immediately which helped her open up
Empathetic, caring!
Can’t recommend Dr van Zwanenberg enough for child ASD/ADHD assessment and follow up. She’s very empathetic & puts everyone in the family at ease.
Very early in our treatment but Dr Hayley has already made a huge improvement to our daughter and her health.
An excellent doctor who is thorough and non-judgemental and takes a collaborative approach.
As always Dr Hayley listens, is empathetic, encouraging and non-judgemental and gives sound professional advice. Thank you.
She is very helpful
She is so kind and supportive
Hayley was amazing with my daughter and she felt very reassured that she would help her get back to her old self!
Dr Hayley is very supportive and I would thoroughly recommend her through this organisation
Without Doctor Hayley I am certain I would not be alive today and she has been a massive help to me and my family.
Dr Hayley was incredibly thorough, supportive and engaged. My daughters confidence with the process soared and throughout the 2.5 hour process. I am profoundly grateful that expertise and care exists in professionals like Dr Hayley. She is life-changingly good.

We have received a very positive experience using Dr van Zwanenberg. We have felt listened to and supported without any judgement getting our daughters autism diagnosis. We would highly recommend.

Dr Hayley was very calming and listened carefully to my concerns
Dr van Zwanenberg’s tone, manner & approach was perfect for our child, she listened to us all and helped set wheels in motion. Thank you
Thank you, I am very grateful for your professional, committed and caring approach that underpins your clients’ healing of minds, developing self-confidence and sustainable growth as autonomous individuals in becoming. I hope you recognise you save lives and give hope with your calm faith that your clients will, and do get better.
Dr van Zwanenberg was very friendly and put my son at ease so he felt comfortable to talk openly. She was very reassuring and seemed to understand him straight away.
Very good doctor.
As always Dr Hayley was fantastic. She is always one step ahead and any additional admin requests etc are never too much bother. We will be sorry to lose her, as my daughter moves on soon to an adult psychiatrist now that she’s 18. I will be surprised if we can get such attentive service from any other psychiatrist. Many thanks indeed for your amazing support over the past few years.
Very approachable and friendly style, felt that she really listened and put our anxious daughter at ease. Explained very clearly what the problem was and how we were going to deal with it as a team. Highly recommend.
When dealing with a person with mental illness it is essential that the patient feels that they are being believed by the Doctor who provides the treatment. Dr van Zwanenberg is able to build trust and rapport and is sympathetic, understanding and non judgmental in her approach.
Very friendly and helpful.
Thank you so much. Straight forward. Caring. & already actioning a plan. I’ve recommended you to two people already
Dr Hayley has been very good for my daughter – she has been kind, caring and has explained her condition to us very well. My daughter was really poorly but is now well on the way to a good recovery thanks to Dr Hayley’s treatment and care.
Very happy with the service Dr Hayley has provided.
Dr Hayley and her colleagues provide outstanding accessible compassionate and effective care for young people with emotional and mental health difficulties including ADHD. We can not thank her and her colleagues enough for the extraordinary difference they have made to my son’s well- being and helping him approach his full academic potential.
Dr Hayley was wonderful with my son. She put him at ease very quickly and consequently he was very happy to open up to her and talk freely. Thank you so much.
The level of care and communication from Hayley has been exceptional throughout and I have already strongly recommended her to several other parents.
Dr hayley is always so positive and encouraging. She listens well, is very professional and is very calming. Always a positive and helpful experience. My daughter won’t speak to any therapists however she is happy to open up to Dr Hayley. Thank you.
Dr Hayley is the only doctor that we trust to help us with our daughter’s mental health; more importantly, our daughter also trusts her. She genuinely cares. She talks to her, understands her and engages with her and us. She quickly identifies the problem and suggests realistic, pro active plans to tackle the particular issues at hand. She is always available for us to contact by phone and email (no matter how small the problem) and has telephoned us during the day and sometimes in the evening when the situation requires it. As parents, we have at times really struggled but she always manages to reassure us and we feel very lucky to have her as our doctor.
Dr Hayley is such a lovely and compassionate psychiatrist. She has transformed the life of my son. I am so grateful.
Dr Hayley took an impressive amount of care in advance of our initial assessment appointment, to evaluate our son’s situation from many angles. We felt listened to and reassaured by her suggestions of strategies to help manage his symptoms. My son commented after the appointment that “She was vey kind and understood me”. We have also appreciated her quick responses to our questions outside of the appointment itself
Thank you so much for a faultless service. I’ve recommended you already to friends!
Dr Hayley van Zwanenberg is a very good doctor
Dr Hayley saved me from suicide and helped me turn my life around. She is the best!
We love Dr Hayley. She is the only person my daughter will engage with. She has been incredibly helpful in all kinds of ways, not only with medication but with diagnosis, advice and referrals. My daughter has come along way since seeing Dr Hayley
I really thought I was going to lose my daughter. Lose her to her own despair and potentially her own life. I searched for what seems like too long to find her the support, acknowledgment and treatment she needed. Finding Dr H was not just a life line but a true life changer. The care, understanding and treatment my daughter has received is truly outstanding. With Dr H’s consultation and understanding, my daughter has been able to reconcile her feelings of despair and inadequacy. I now have a confident, happy, social daughter who is starting university in the autumn and is looking forward to life. I can not thank you enough Dr H. Honestly, thank you so very much.

Dr Hayley is always really professional but totally relatable and understanding. Would definitely recommend her to others.

Dr Hayley probably saved my son’s life. A great Doctor.
Hayley has always been very accessible and helpful if we’ve needed to contact her between appointments.
Dr van Zwanenberg was fantastic, everything we’d hoped for.
Brilliant Doctor, I gave up and Dr Hayley picked me back up and got be back to myself. I feel like she actually cares and respects what I say.
Van Zwanenberg was able to see us much more quickly than we had expected for which we were very grateful, and we were touched by the level of care and personal attention we and our son were afforded when we met. The speed, depth and quality of the written follow up was impressive, too.
Dr Hayley has made my child’s life happy again, and our families too. She has identified and helped him with his anxiety and adhd. Her practice is run with precision and care with excellent communication from Dr Hayley and her team. I can’t thank them enough.
I was highly recommended to yourselves by someone who had previously been to see you. I will also highly recommend you also. My husband and I Felt very at ease during the whole process.
