Frequently Asked Questions

A private ADHD assessment is a comprehensive evaluation carried out by a qualified mental health professional to determine whether you meet the criteria for Attention Deficit Hyperactivity Disorder (ADHD). At Harley Street Mental Health, our private adult ADHD assessments in the UK include an in-depth clinical interview, evidence-based diagnostic tools such as the DIVA 5.0, and a review of developmental history and current symptoms. Assessments typically explore how ADHD symptoms impact areas such as work, education, relationships, and daily functioning.
Choosing a private ADHD assessment offers faster access to diagnosis and treatment compared to NHS waiting times. Following the assessment, a formal diagnostic report is provided, and if a diagnosis is confirmed, we offer guidance on ADHD treatment options, including medication, therapy, and lifestyle strategies.
Yes, all of our private ADHD assessments at Harley Street Mental Health are fully compliant with the National Institute for Health and Care Excellence (NICE) guidelines for the diagnosis and management of ADHD. We go beyond the standard requirements by also following the Associated Quality Assured Standards (AQAS) developed by UK adult ADHD specialists. This ensures that our assessments are not only evidence-based but also reflect best practices in the field.
Our clinicians use validated diagnostic tools such as the DIVA 5.0 and follow a structured clinical interview format that meets and exceeds NICE standards. This comprehensive approach includes a detailed review of your developmental history, current symptoms, and the impact of ADHD across different areas of life, including education, work, relationships, and everyday functioning.
By exceeding national guidelines, we aim to provide the highest standard of ADHD care available privately in the UK.

ADD (Attention Deficit Disorder) and ADHD (Attention Deficit Hyperactivity Disorder) refer to the same condition, but the terminology has evolved. ADHD is the current medical term used to describe individuals who have difficulties with attention, impulsivity, and/or hyperactivity, even if hyperactivity isn’t a prominent symptom.
Historically, ADD was used to describe individuals who had trouble with attention and focus but did not show signs of hyperactivity. Today, this would be diagnosed as ADHD, Predominantly Inattentive Presentation, one of three recognised subtypes under the modern ADHD diagnostic criteria.
At Harley Street Mental Health, we assess for all presentations of ADHD, including:
- Predominantly Inattentive Type (formerly known as ADD)
- Predominantly Hyperactive-Impulsive Type
- Combined Type
Yes, we have a dedicated team of CAMHS consultant psychiatrists that can diagnose and treat ADHD in individuals aged under 18
If you have been diagnosed elsewhere, and want to transfer your care to Harley Street Mental Health please do get in touch and we can guide you through the process.

What our patients say about us
Read real experiences from our patients—trusted, professional care that makes a lasting impact on mental health.
I had a very positive experience from booking through to receiving my report.
Booking the appointment was straightforward and easy to do. I particularly liked that the website provided a list of the available clinicians along with information about their professional backgrounds, experience and the areas they work in or have previously worked in. This gave me the opportunity to do my own research and choose someone I felt comfortable with rather than simply being assigned a clinician. After looking through the available options, I chose Dr Sijjad Ijaz, Specialty Doctor, for my ADHD assessment.
The appointment itself was well structured and clearly paced, but also relaxed and down to earth. It felt much more like having a genuine conversation than going through a formal interview, which made it much easier for me to speak openly.
Most importantly, I genuinely felt listened to. Dr Ijaz gave me the time to explain my experiences properly and I never felt rushed, dismissed or as though we were simply working through a checklist.
Everything was explained clearly, including what would happen afterwards and what I should expect next. I was also very impressed by how quickly the report was completed. It arrived well within the stated timeframe and much faster than I had expected.
The appointment did start a little later than scheduled, but Dr Ijaz was very apologetic about the delay and I completely understand that these things can happen when working directly with people.
Overall, the whole process felt professional, approachable and well organised. I was very happy with my experience and would definitely recommend Dr Sijjad Ijaz.
I had been putting this off for years and really struggled to get the courage to go through the process of getting diagnosed. I didn’t have the best experience with my GP so I chose Right To Choose so I could really research where would be best for me.
It was a really quick process after the paperwork had been completed.
Both Dr Sijjad Ijaz and Karmen Gadi were really friendly and knowledgeable, they took the time to listen and made me feel understood and safe to share my experiences.
I would highly recommend, they have been so helpful and really made the process so much smoother than I ever would’ve anticipated. I came away feeling better than I have in a long time because I felt safe enough to talk freely and felt understood.
Thank you!
Seeking help with ADHD is an important personal step, and I’m very grateful for Dr Ijaz’s support. His care deserves special recognition, and I would highly recommend him to anyone considering an assessment.
I reached out about a Right-To-Choose ADHD Assessment and spoke to Neisha & Adam via email. There was a chance to get a fast assessment due to slots being made available by my ICB, but only a small number so time was of the essence. Neisha liaised with my GP on the same-day as I initially got in touch in order to make everything go as quick as possible and she had the referral processed that same day too. I had the pre-assessment questionnaire within 24 hours of that. Neisha & Adam were a joy to chat with and incredibly kind and helpful with getting everything sorted.
As of time of writing, I've now had my assessment (this morning in fact). I met with Dr Ali Taufeeq, who was absolutely brilliant. He conducted the assessment with real, genuine empathy and kindness. I was quite nervous for it but he was very patient with me and guided the assessment very smoothly and professionally. His calm and gentle demeanour made it very easy for me to open up and describe things in detail.
I'm extremely impressed with, and grateful for, the whole team at Harley Street Mental Health.
My assessment was with Dr Sijjad Ijaz, and the experience was excellent from start to finish. Having previously been diagnosed with ADHD in another country, I have something to compare it to, and this was by far the best experience I’ve had. Dr Ijaz immediately put me at ease, took the time to listen, and was professional, knowledgeable, and genuinely compassionate throughout the assessment.
The entire process was smooth and efficient. I received my diagnostic report within a week, and I was able to start medication just a few days later. Everything was clearly explained, communication was excellent, and I felt supported every step of the way.
If you’re considering an ADHD assessment, I wouldn’t hesitate to recommend Harley Street Mental Health, and especially Dr Sijjad Ijaz. His expertise, professionalism, and approachable manner made the entire experience a positive one.
Titration was also very smooth sailing. Adil was very patient and answered all of my questions in full, taking time to explain everything. He was very knowledgeable and offered lots of advice.
Highly recommend HSMH, they have been very accommodating, very helpful and the communication has been brilliant. Truly help people to understand themselves!
Dr Sullivan is incredibly kind, professional and supportive and genuinely cares for her patients. It is entirely down to her efforts that our son is now back at university, repeating his first year but this time with the support he needs to keep on track. It is a huge relief for all of us to understand why things went wrong after achieving so well academically in the structured environment of home and school, and her advice is clear, pragmatic and effective.
We would like to thank the team at HSMH for their efficiency in getting things done quickly and for facilitating the assessments at short notice, and Dr Sullivan in particular for being so calm, caring and non-judgmental yet giving clear direction about what to do during what was a fairly stressful time for us. Our experience was exceptional from start to finish.
Thank you for providing such an excellent service.
He took the time to explain everything clearly and talked me through the different treatment options available, without making me feel pressured to choose one over another. I felt like he genuinely listened to me and wanted to help me find what would work best for my situation.
He also explained how I could go about getting my diagnosis and medication onto the NHS in the future, which was really helpful.
Overall, I felt heard, understood and supported throughout the appointment. I really appreciated his approachable manner, sense of humour and the care he took to explain everything.
Was able to ask questions and felt listened.
Explanations were good.
Saw Mohammed Raza, would recommend.
I chose HSMH because not only did they have good lead times, but they could work on shared care agreements with your GP, and most importantly if for any reason your GP refused shared care (as far as I am aware I don't think mine would but you never know in future) HSMH can also prescribe on the NHS. From what I could tell, many private clinics wouldn't.
Once the GP sent their referral for an assessment to HSMH it was so quick, they contacted me the next day to book an appointment. As they have several practitioners there were even appointments available that week. Given you can choose which of their clinicians assesses you, I went through their individual profiles and chose Dr Benjamin Walters whose next availability was only 2 weeks away. I was assessed and diagnosed during that same call which was a relief not to have to wait. Benjamin was excellent, very empathetic to my situation and very informative, I finally felt supported. He discussed all the options and informed me there was a 16-20 week wait for titration (reviewing medication options and starting medication) and it was indeed 16 weeks to the day that I was contacted to book an appointment. I chose Adil Yousaf as my pharmacist as he was the Lead Clinical Pharmacist and for being known for his patient centred approach, he was equally excellent, very informative and clear in his communication, and knew exactly what to recommend. The medication has literally been life changing.
I can't thank HSMH enough.
The entire process has been much quicker than I anticipated, clear and smooth.
*Just a heads up the forms and questionnaires can be overwhelming, however knowing that you can only receive your appointment once completion creates a sense of urgency, which aided task initiation for me* earliest availability for my chosen assessor was 1 month from form completion. And 1 month between next assessment.
Dr Benjamin Walters completed both of my assessments for continuity of care, which I found reassuring. Ben was clear, professional, patient, knowledgeable and kind throughout. Taking time to explain and provide reassurance on what the assessment would entail, allowing time for me to process questions and prepare answers. I was hugely relieved, reassured and grateful that Ben had extensive knowledge around high masking/camouflaging females, as well as, understanding how neurodivergent traits can be directly exacerbated by female hormones. Which was also encompassed within my report. After each assessment I had a panic around not expressing everything that I had planned to. Ben always provided time for me to look at my own notes/lists and add what I felt necessary. I hadn’t needed to worry over this either, as Ben had thoroughly read through all of my forms and referenced so much of the information from them within my reports to ensure they were fully formed.
Than you for handling such vulnerability and truth with the upmost care 🙂
I had my consultation with Dr Ijaz, and he was absolutely amazing. From the moment we got on the call, he was very understanding, non-judgemental, and really encouraged me to reflect. He made the whole process feel seamless and comfortable.
The additional communication with Adam, the receptionist, was also excellent. He was incredibly responsive, answered all my questions, and got back to me quickly every time, which made the experience much less stressful.
Although I did have to go through the MDT process, I was kept fully informed throughout and was told exactly what information I needed to provide. I found filling in the forms quite stressful, but at no point did I feel pressured or rushed.
The final report was sent within a week (or even slightly less) and was extremely detailed. Overall, I couldn’t have asked for a better service .It was professional, thorough, and very efficient.
I would 100% recommend them to anyone looking for a clear and speedy diagnostic process!!
I had Dr Sullivan for both assessments, and she was wonderful throughout. She made the assessment feel like a genuine conversation rather than a clinical interrogation, and I felt completely comfortable being open with her. Her expertise really stood out too, she was able to separate the different aspects of my presentation, pinpoint exactly which symptoms belonged to which condition, and give me a clear, coherent picture after a lifetime of confusion. Even in the written report itself, she took the time to include real encouragement and acknowledgement of my strengths and everything I'd navigated without a clear picture until now, which genuinely meant a lot to read.
I also have to mention Adam, who was my first point of contact throughout the process. He responded to emails so quickly, made everything feel easy and stress-free, and made sure an important document reached Dr Sullivan in time for my appointment. People like that genuinely hold a place like this together, and that kind of behind-the-scenes diligence doesn't get thanked enough, so a BIG thank you to you too!!
Thank you to the whole team for such a thorough, kind, and validating process.
The assessment was extremely thorough and I genuinely felt listened to and understood. When I received my full report, I was amazed by the amount of detail and how accurately it captured so many of the difficulties I've struggled with over the years.
After finally receiving my ADHD diagnosis at 56, the whole process has helped me understand myself and many of my past experiences much better. I'm very grateful for the support I received and would happily recommend the service.
Once I had completed the paperwork, it was really easy, and surprisingly quick, to book an appointment for an ADHD assessment.
My assessor was really amazing at putting me at ease and so patient, listening to everything I had to say and pulling out the key information. I really felt heard and validated, which is so important in this context.
I would highly recommend choosing this organisation. Thank you HSMH
