Super quick to respond to emails/phone calls, and little to no wait for appointments

All the staff I've interacted with have been super helpful & professional. I've had Annisah for my medication reviews, and she's been fantastic through the entire process

Highly recommend! It beats waiting 3+ years for an NHS appointment a thousand times over 😅

 Trustindex verifies that the original source of the review is Google. I had my ADHD assessment with Janine and couldn't have been happier with how it went. I was quite worried and nervous beforehand, but Janine made me feel at ease very quickly. She was friendly, understanding and really easy to talk to, which made the whole assessment much less daunting than I expected. I felt comfortable being open and honest with her and never felt judged or rushed. I'm really grateful for how she handled the assessment and would definitely recommend her to anyone feeling nervous about going through the process. Thank you, Janine!

Frequently Asked Questions

Do I need a GP referral?

No. We operate as a self-referral service. You can book directly without speaking to your GP first. If you would like your GP to be informed of your diagnosis, your report can be shared with them following your assessment.

How long does the adult ADHD assessment take?

The clinical assessment session is 90 minutes for adults. You will also complete two pre-assessment questionnaires in advance, which take approximately 20–30 minutes each.

How quickly will I receive my report?

Your full written report is delivered by email within 10 working days of your assessment. It includes your diagnostic outcome, clinical rationale, treatment plan, and supporting letters.

Can I get medication after a private diagnosis?

Yes. If medication is recommended as part of your treatment plan, our clinicians can prescribe directly. Medication is dispensed via our partner pharmacy and delivered to your home.

What is the difference between ADHD and ADD?

ADD (Attention Deficit Disorder) is an older term that is no longer used in clinical diagnosis. The current diagnostic classification under DSM-5 and ICD-11 uses ADHD (Attention Deficit Hyperactivity Disorder), with three recognised presentations: Predominantly Inattentive, Predominantly Hyperactive-Impulsive, and Combined. Your report will specify which presentation is most consistent with your clinical picture.

What if my assessment does not result in a diagnosis?

Not all assessments result in an ADHD diagnosis. If your clinician concludes that ADHD is not the primary explanation for your difficulties, your report will include clinical observations and, where appropriate, recommendations for further assessment or alternative support pathways.

Online vs In-Person ADHD Assessment for Adults: Are They Clinically Equivalent?

Yes. Both online and in-person ADHD assessment for adults follow the same DSM-5-compliant clinical protocol and produce the same comprehensive report. The online assessment is conducted via a secure video call with full ID verification.
