Not sure where to start? A screening consultation can help
If you’re unsure whether your child needs a full neurodevelopmental assessment, or which assessment might suit them best, a screening consultation is a good first step.
The consultation lasts one hour and can take place in person or remotely. A Clinical Psychologist will carry out a structured clinical interview to explore your child’s mental health and neurodevelopmental history, using validated screening tools suited to their needs.
At the end of the session, you’ll receive personalised recommendations – which might include a neurodevelopmental assessment, psychological therapy, or a psychiatry consultation. If you’d like to go ahead, we can arrange any internal referrals and you’ll receive a written summary that can be shared with your child’s GP.
Stage 1: your initial consultation
You and your child will meet with a Consultant Psychiatrist, Specialty Doctor, or Clinical Psychologist for a Comprehensive Clinical Assessment. This includes gathering clinical information from parents/carers and observing your child in the clinic setting, discussing the difficulties they experience at home and school, and looking into any co-existing conditions.
You’ll be given the SNAP-IV Comprehensive Behaviour Rating Scales and a Developmental History questionnaire to complete. We’ll also contact your child’s school to gather detailed educational information, and ask staff who know your child well to complete the SNAP-IV.
Stage 2: your in-depth assessment
This comprehensive, multidimensional assessment covers the impact on school, home, and social functioning, across two appointments:
Developmental History appointment (parents only) – a standardised interview covering your child’s early years and developmental history in depth, recommended in current national guidelines.
ADOS-2 appointment (child only) – a play-based observational assessment, also recommended in national guidelines, where your child plays with specific toys and completes age-appropriate tasks with one team member, while another observes.
Stage 3: your feedback appointment
Once assessment is complete, our team gathers all the information and maps it onto the DSM-5 criteria for autism and ADHD. Where all information is available, we aim to feed back within 6-8 weeks of the clinic assessment.
You and your child will attend a feedback appointment with the Consultant Psychiatrist, Specialty Doctor, or Clinical Psychologist to discuss the results. If a formal diagnosis is given and medication is indicated, you’ll receive detailed post-diagnostic information and resources, with time to consider next steps. Recommendations will also be made for psychosocial and behavioural interventions where appropriate.
A comprehensive report is sent to you, your child’s GP, and their school (with your permission) around 4 weeks after your feedback appointment.

FAQs
Autism and ADHD often co‑occur and share overlapping traits. A combined assessment helps clinicians understand whether difficulties are best explained by one condition, both, or another factor entirely — and avoids unnecessary repetition of assessment steps.
Yes — as part of the in‑depth assessment, your child will complete the ADOS‑2, a structured observational assessment designed to identify behaviours associated with autism in a play‑based, age‑appropriate setting.
The assessment is carried out over several appointments. Once all the questionnaires, developmental history, clinical observations and school feedback are gathered and reviewed, our multidisciplinary team meets to review the information. Feedback is typically provided within about 6–8 weeks after the main clinic assessment, assuming all relevant information is received.
Assessments can sometimes have a waiting list. To secure a place on the waiting list, a £200 non‑refundable deposit is required and this amount is deducted from the total assessment cost once booked.
If the team concludes that behaviours don’t meet the formal criteria for Autism or ADHD, you will still receive detailed feedback and suggestions for appropriate support or referral pathways based on your child’s strengths and challenges.
