A small, multi‑disciplinary practice for Autism, ADHD and mental health assessments - for children and adults. Harley Street, Ware, or online.
RDA Autism & ADHD Practice provides specialist, high‑quality and individualised assessments for children and adults seeking a private Autism or ADHD diagnosis. Our clinicians work collaboratively, with a strong commitment to neuro‑inclusion at every stage of the process.
We value each individual's personal journey, adopting a trauma‑focused approach. Alongside diagnostic assessments, we offer specialist services across psychiatry, psychology, speech & language therapy and occupational therapy.
RDA Autism & ADHD Practice is regulated by the Care Quality Commission and follows guidelines set out by the National Institute for Health and Care Excellence. No GP referral is required to book in.
Currently, across health services Autism and ADHD assessments frequently involve waits of one to three years or more. For many individuals and families, that gap is the difference between coping and feeling isolated with no guidance. RDA Autism & ADHD Practice was established to support those who cannot afford to wait, who require timely, compassionate care, providing thorough, multidisciplinary assessments without the need for a GP referral, without long queues. We value a thoughtful, multidisciplinary assessment not a quick, single‑assessor model. Our approach brings together the right clinicians to build a fuller, more meaningful understanding of each person.
Ready when you are
Compassionate, trauma‑informed and considered care. Every clinician who joins us shares one commitment: to make a meaningful difference in people's lives.
Our team is led by a GMC‑registered Consultant Child & Adolescent Psychiatrist and an HCPC‑registered Chartered Counselling Psychologist, supported by a Consultant Paediatrician, Occupational Therapist, Highly Specialist Speech Therapist, Clinical Psychologists, Nurses and many more clinicians.
We are guided by clinical expertise, evidence‑based and neurodivergent‑led research, and lived expertise. Our pathways evolve continuously to stay aligned with emerging evidence and the feedback we receive.
Research demonstrates neurodivergent people such as Autistic adults experience trauma in both the traditional understanding of trauma and in broader, cumulative ways. These experiences differ from non‑neurodivergent people. We hold space for them with care and understanding.
A pre‑assessment form will be sent to gather any background information required, and some screeners that help shape the next steps.
Book the assessment that fits - Child Autism, Child ADHD, Child Combined Assessment, Adult Autism, Adult ADHD, Child Psychiatry and more.
Whether you receive a diagnosis or not, you are given recommendations tailored to your assessment outcome. The outcome of a diagnosis can mean different things for different people. You may wish to end your journey here, you may wish to try pharmacological interventions for treatment or book in a follow‑up consultation. We share signposting information and advice as appropriate.
Each assessment involves a robust process: gathering background information, reports from different sources, and a diagnostic assessment. We offer some concessionary clinics at a reduced rate - please call us for more information.
