Assessment Process Explained
At ISC-Care, our Adult ADHD assessments are delivered through a structured and clinically rigorous two-stage process to ensure accuracy, transparency, and compliance with best practice standards. The assessment is conducted by a Master’s-level Assistant Psychologist and lasts up to 90 minutes. Appointments are available remotely via Microsoft Teams or in person at our Liverpool or Leeds clinics. During this appointment, we undertake a detailed exploration of current symptoms, developmental history, functional impact, and screening measures in line with NICE guidance.
Following the assessment, your case is reviewed within our multidisciplinary framework and a 25-minute Microsoft Teams consultation is arranged with our Consultant, who finalises the diagnostic formulation and confirms the outcome. This Consultant appointment is included within the assessment fee. This robust two-stage model ensures that every Adult ADHD assessment is thorough, evidence-based, and clinically sound, providing a clear diagnostic report that can be shared with your GP or other healthcare professionals to support onward care where appropriate.
Assessments typically last up to 90 minutes, and cost:
£495 - Essential package - Consultant-confirmed ADHD diagnosis with a formal report suitable for GP sharing, treatment or titration pathways, and third-party services.
£745 - Enhanced package - All Essential package elements plus full DIVA-5 symptom report, personalised adjustments report for employer, school or university, and Consultant follow-up consultation.
Means-tested reductions of up to 40% are available on our Essential ADHD Assessment package
Treatment & Titration
Following diagnosis, you may choose to begin titration, a structured 12-week process where our prescribers help you find the most effective medication and dose. Therapy can be combined with titration for additional support.
Treatment options:
Titration Package (3 sessions): £390
Titration + Therapy Package (3 prescriber + 3 therapy sessions): £510
Individual Titration Session: £145
Individual Therapy Session: £65
Therapy Package (6 sessions): £340
Shared Care
Once stable on medication, we may arrange a Shared Care Agreement with your GP so prescribing can transfer to the NHS. If shared care is declined, prescriptions and reviews can continue privately.
Shared Care setup fee: £50
Six-monthly reviews: £120
Private prescriptions (max 28 days): £33.50
