Private ADHD Assessments for Adults
Don't let long waiting lists delay the support you need. We provide neuro affirming private ADHD assessments for adults with significantly shorter waiting times. Our approach is respectful, evidence based, and tailored to your lived experience. Whether you are seeking a first diagnosis or greater understanding later in life, our clinicians are here to help you gain clarity and access appropriate support.
You can enquire about our private services or book a free 30‑minute consultation using the buttons below.
Please note: the free consultation is available only for clients considering a privately funded assessment and we’re unable to discuss the NHS Right to Choose (RTC) pathway.

Post enquiry, a member of our clinical team will arrange a pre-assessment call to ensure that we are able to deliver the right assessment for you/your child/family member.
Post the pre-assessment call, we will send you an invoice. Once settled, we will send out our pre-assessment questionnaires. For children, this will include a school-based questionnaire or home education questionnaire. At this point, we will also request a GP medical summary from your GP or your NHS app. When the pre-assessment questionnaires and GP summary have been returned, these will be revised by our clinical team.
Following our clinical review, we’ll reach out to you to arrange assessments. ADHD: 1 assessment slot approximately 2 ½ – 3 hours. Autism assessment: 2 sessions, ADOS/observation assessment approximately 90 mins, and ADI-R assessment 2 ½ – 3 hours.
Post-assessment, the clinical team meets for a multi-disciplinary team discussion, following which you will be called (phone or via video call) with the outcome of your/your child’s/family member’s assessment.
After the outcome, you will receive the diagnostic report and any onward recommendations.
What to expect from your private ADHD assessment
Our private ADHD assessments for adults provide a clear, supportive pathway from initial enquiry through to diagnosis and recommendations.
Step 1
Enquiry
Once we receive your enquiry, we will contact you to begin your private ADHD assessment process.
We’ll gather background information, confirm the appropriate assessment pathway, and issue your invoice. After payment is received, you will be sent questionnaires to complete. Where possible, we may also request input from someone who knew you in childhood to support developmental history.
Step 2
The
Assessments
We will book your assessment appointment once your questionnaires have been reviewed.
A clinician will complete a structured ADHD assessment exploring attention, organisation, impulsivity, and day-to-day functioning. We will review questionnaire responses and developmental history to understand how ADHD traits have presented over time. Following the assessment, clinicians review all information and present your case at a multidisciplinary team meeting.
Step 3
Diagnosis
Our multidisciplinary team will review all information to make a clinical decision.
Your clinician will contact you to discuss the outcome, answer any questions, and explain recommendations. You will also receive a full written report detailing your diagnosis and personalised support recommendations.
