The Adult Autism Practice

What The Adult Autism Practice does

The Adult Autism & ADHD Practice is a clinical diagnostic service provider founded by Prof Davida Hartman and based in Dun Laoghaire, Ireland, with operational activity since 2020 and formal founding in 2022. It delivers specialist diagnostic assessments for autism, ADHD, and combined presentations in adults, using a structured multi-session clinical model priced at approximately €1,500/£1,300 for a single-condition assessment and €2,500/£2,165 for a combined assessment. The practice operates an online-only delivery model via Microsoft Teams, enabling service across the UK and Ireland without physical clinic infrastructure, and serves a direct-to-consumer client base of adults seeking formal diagnosis. It is staffed by 50+ psychologists, many of whom bring lived experience as autistic or ADHD clinicians, and has served over 5,000 clients since inception.

The business model is a mix of individual assessment fees, follow-on consultations (€300/£260 per session), follow-on ADHD assessments (€1,000/£845), an optional disability letter (+€100), and a separate professional training revenue stream priced at €2,500 (half-day) and €3,500 (full-day). The practice extends its offering through partnerships with Thriving Autistic, Horizons Therapy, and Céira Moroney for post-assessment support, and its clinical documentation is accepted by the NHS and HSE. The company has published the first book on adult autism assessment (2023) and a companion child autism assessment handbook (2025), positioning itself as a methodological authority in the adult diagnostic niche rather than a generalist telehealth provider. There are no disclosed funding rounds, indicating the business has been financed organically from service revenue.

Direct peers

• Clinical Partners: UK private mental health and neurodevelopmental assessment provider offering adult ADHD and autism assessments online. Comparable as a private-pay, self-referral, psychologist-led adult diagnostic service competing for the same UK/Ireland self-paying client base.
• Psychiatry UK: UK-based online private provider of adult ADHD and autism assessments and treatment, including medication titration. Most directly comparable peer: same geography, same online-delivery model, same adult neurodevelopmental assessment focus, but with a stronger medication-prescribing arm.
• The Owl Centre: UK-based provider of private autism and ADHD assessments for adults and children via a network of clinicians. Comparable private-pay diagnostic model and multi-clinician delivery structure serving a similar adult assessment-seeking population.
• Dr J and Colleagues: UK private adult ADHD and autism assessment service using a similar online, psychologist-led, self-pay model. Competes for the same UK adult self-referral market with comparable assessment-style offerings.
• The Children's Clinic: Co-founded by the same founder (Prof Davida Hartman) in 2016; provides private autism and psychology services, focused primarily on children. Directly comparable clinical model and methodological lineage, and a likely precursor / sibling entity to the subject practice.
• Harley Therapy - ADHD and Autism Centre: UK private psychology practice offering adult ADHD and autism assessments online. Comparable private, assessment-focused, self-pay model targeting the same adult UK/Ireland client segment.

Broad incumbents

• The London Psychiatry Centre: Established UK private psychiatry practice offering adult ADHD and autism assessment and treatment including medication. Broader incumbent offering overlapping adult diagnostic capability within a wider private psychiatry portfolio.
• Aspris (formerly Priory Healthcare): Large established UK private healthcare group offering autism assessment and broader mental health services. Broader incumbent providing overlapping adult assessment capability within a much wider portfolio of inpatient and outpatient services.

Others

• Thriving Autistic: Award-winning non-profit partner providing post-assessment support, community programmes, and the Neurodivergent Practitioners Directory used by The Adult Autism & ADHD Practice. Adjacent ecosystem participant rather than a competitor, since it provides aftercare and referrals rather than assessments itself.

Emerging players

• Taliaz Health: Digital health company offering AI-supported online ADHD and autism assessment and treatment pathways in the UK. Comparable target population and digital-first delivery, but with a more technology-led, prescribing-included model that contrasts with the practice's clinician-led methodology.
