I’d think twice before using this clinic. There are hidden costs and time-constraints to receiving treatment. I had my ADHD assessment here in August 2025 and received a positive diagnosis. The assessment was great, BUT… At no point before paying was I told that a positive diagnosis would require multiple additional paid consultations (£150 each) plus repeat prescription charges (£45 each), before they would be willing to hand over to my GP for NHS shared care. These ongoing costs were only made clear after I’d committed, paid for the assessment, and received the diagnosis. I was then sent a questionnaire to complete before a prescription could be issued, with no mention of any time limit, and no follow up. I delayed completing it by 8 months to save money to pay for treatment, because I wasn’t able to afford their (multiple) additional titration fees immediately after diagnosis, and I understood that once starting treatment, I would need to continue it. After eventually completing it, I was told I now have to pay for another £150 appointment purely because time had elapsed - at no point in the 8 months did they follow up or warn me about a time limit. This is especially concerning as their own assessment cited “difficulties with completing tasks on time” and “trouble with organisation and memory” as symptoms of my condition - yet they made no effort to follow up. I have since tried to raise a complaint but they are refusing to acknowledge it because “over 6 months has elapsed” - an arbitrary and self-imposed limit which seems to just be their effort to bury the issue. For a mental health service, leaving a patient stuck without medication is disappointing. I’d urge anyone considering this clinic to get the full cost of the entire pathway in writing before paying anything. They seem to just be money-grabbers and not transparent about the full costs.
I had my assessment with Dr Sijjad Ijaz today, he made me feel so comfortable and at ease and it felt like just talking to one of my friends! He was so thorough, made me laugh and made lots of lighthearted jokes but was also very informative and professional. He made me feel much better about my mental health & the impulsive thoughts I get, and also really validated my emotions towards my diagnosis of ADHD. Would highly recommend Harley Street & Dr Sijjas Ijaz, once all my questionnaires and forms were completed, I had the appointment within a couple of days! I’m so glad this is where I chose for my assessment, I feel such a massive sense of relief now😊
I had my ADHD assessment with Dr Scot Lindsay and found the whole experience very positive. From the start he made me feel welcomed and at ease, which helped me feel comfortable talking openly about my symptoms and experiences. Throughout the assessment he listened carefully and never made me feel rushed. I felt that he genuinely understood what I was describing and took the time to ask thoughtful questions so he could fully understand my situation. His calm and supportive manner made the conversation feel safe and non-judgemental. Overall, I felt heard, respected, and well supported during the assessment, and I really appreciated the care and understanding he showed during the assessment.
I had an excellent experience with Dr Sullivan and cannot recommend them highly enough. From the very beginning, they created an environment that felt genuinely welcoming, open, and completely non-judgemental. It was clear that they took the time to truly listen and understand what I was saying rather than rushing through the conversation. What stood out most was how comfortable the whole interaction felt. Speaking with Dr Sullivan was remarkably easy and natural — it felt less like a formal appointment and more like talking with an old friend who genuinely cares about your wellbeing. At the same time, their professionalism, knowledge, and thoughtful guidance were evident throughout. Dr Sullivan has a wonderful ability to balance warmth with expertise. I left the appointment feeling heard, understood, and supported, which is something that makes an enormous difference when discussing personal matters. I’m very grateful for the experience and would highly recommend Dr Sullivan to anyone looking for a compassionate, attentive, and highly professional doctor.
I had my ADHD assessment with Dr Sarah Sullivan today and I just wanted to share how positive the experience was. Dr Sullivan was incredibly kind, patient, and understanding throughout the entire appointment. She made me feel comfortable from the start and created a really supportive environment where I felt listened to and taken seriously. The assessment was thorough, but it never felt intimidating or rushed. What stood out the most was how compassionate and validating she was. After waiting a long time for an ADHD assessment, it meant a lot to speak with someone who genuinely understood and approached everything with empathy and professionalism. I’m really grateful for the care and attention she gave during the assessment and would absolutely recommend her to anyone going through the ADHD assessment process.
I recently completed the 2 day ADHD training with Harley Street, and I can confidently say it has been one of the most valuable and impactful professional development experiences in my six-year career. The training was exceptionally well-structured, precise, comprehensive, and delivered with great clarity, ensuring that every essential aspect of ADHD assessment and management was thoroughly covered. Before attending, I was somewhat sceptical of the company’s high Google ratings, assuming they might be exaggerated. However, after participating in the training, I can say without hesitation that the reviews are a true reflection of the outstanding quality they offer. The facilitator was phenomenal engaging, knowledgeable, and clearly passionate about the subject matter. Their delivery was so excellent that they deserve far more than a five star rating. Another remarkable strength of Harley Street is the depth of expertise across their team. Throughout the sessions, there were multiple highly qualified professionals available to respond promptly and effectively to questions in the chat. This ensured that no query went unanswered and that every participant received meaningful support. Thanks to this training, I now feel fully equipped and 100% confident in my knowledge of ADHD assessment, management, and best clinical practices. The content was not only informative but delivered in a way that kept the entire two days engaging from start to finish and there was truly no dull moment. Every section offered valuable information that I would not want to have missed. I would wholeheartedly recommend Harley Street’s ADHD training to any professional seeking to expand their expertise, enhance their clinical competence, or gain a deeper understanding of ADHD. This programme is a model of excellence and an investment that delivers exceptional value.
After wanting to pursue an ADHD assessment for a long time, I decided to go private with Harley Street Mental Health due to long NHS wait times. The wait for an appointment was very short and the forms were emailed immediately to me. My appointment with Dr Sijjad Ijaz was great. I was very nervous going into it, but I instantly felt comfortable and listened to throughout. After being diagnosed, treatment information was provided straight away, meaning I can access medication as soon as my report comes through, which is brilliant. Getting in touch with the company was also very easy, with quick responses by both email and phone which I really appreciated. I would highly recommend them to anyone, it has been completely worth it for me.
I had a wonderful experience with Dr Sullivan. I chose Harley Street Mental Health practice for my ADHD assessment as the waiting list was very reasonable. I was able to choose from many highly trained and experienced clinicians and was drawn to Dr Sullivan as I just knew, instinctively, that she would be warm and compassionate. She is highly skilled, kind and talked me through the extensive process, with open and clear communication. She was able to navigate my complex familial background in a way that was relevant to my diagnosis. As a result, I have a renewed sense of possibilities in living a better life. I am looking forward to seeing Dr Sullivan soon to discuss my next steps I highly recommend Harley Mental Health for support with ADHD and assessment
