Understanding Neurodiversity Across All Ages
At Total Health West Berkshire, we offer thorough, respectful assessments for Autism Spectrum Disorder (ASD) in both children and adults. Whether you’re seeking answers for a child who seems to experience the world differently, or you’re an adult reflecting on lifelong patterns, an autism assessment can bring valuable clarity, understanding, and direction.
“Autism diagnoses in England have surged in recent decades, pushing NHS services to their limits.”
What Is Autism?
A diagnosis of autism can help individuals access the right support, reduce misunderstandings, and feel more at ease in their lives.
Our Children's Autism Assessment Service Starts in Autumn 2025.

Adults With ADHD
Have You Wondered If You Might Be Autistic?
Many autistic adults go undiagnosed until later in life.
Often, after years of feeling “different,” misunderstood, or overwhelmed in social or sensory environments.
You might consider an assessment if you:
- Find social interactions confusing, exhausting, or stressful
- Prefer structure, routine, or solitude to spontaneous plans or crowds
- Have intense interests or deep focus in specific areas
- Are sensitive to light, sound, touch, or other sensory input
- Experience difficulty with change or transitions
- Feel you’ve been “masking” or copying others to fit in
- Have a history of anxiety, burnout, or misdiagnosed mental health conditions
Why Seek an Adult Autism Assessment?
- Deeply validating—helping explain lifelong patterns or challenges
- A starting point for building self-compassion and understanding
- A path toward better communication with others
- A tool for accessing workplace accommodations or community support
- A way to connect with other autistic individuals and feel less alone

What to Expect From an Autism Assessment
Our autism assessments are tailored to your needs and are delivered with empathy, expertise, and care.
The process typically includes:
- An initial consultation to understand your concerns
- Questionnaires and screening tools
- A detailed developmental history
- Observations and/or interviews (with teachers, parents, or partners where appropriate)
- A comprehensive written report and personalised recommendations
Autism Pre-Assessment
Once you have decided that you want to book an assessment, contact us by telephone, via WhatsApp, or by Email.
We will need:
A name, DOB, phone number, Email, and Address.
Pre-Assessment Forms:
We’ll send you pre-assessment forms (some for you, others for someone who knew you as a child). Once these, along with your GP’s Summary Care Record (SCR), are returned, we’ll have everything we need to book your autism assessment.
Autism Assessment Booking
We will contact you to book your autism assessment. It includes two appointments – an ADOS assessment and an ADI-R assessment. Payment is required at least 48 hours before your first appointment.
Autism Main Assessment
Your autism assessment can be done online or in person at Total Health West Berkshire. It includes an ADOS assessment (about 1 hour) and an ADI-R assessment (up to 2 hours), with breaks available and the option to bring someone with you. After both assessments, our clinicians will hold a multidisciplinary meeting to decide on a diagnosis.
If needed, a clinical psychologist may be consulted before a final decision is made. You’ll then have a feedback appointment to discuss the outcome, ask questions, and plan next steps. A full written report will be sent to you afterwards
We Are Here to Help With Your Autism Journey
Autism assessments can be life-changing—for both children and adults.
Understanding yourself or your child better opens the door to a more confident, supported, and meaningful life.
Frequently Asked Questions About Autism Assessments
Do I have to complete the pre assessment forms?
The pre-assessment forms are a vital part of your assessment, so we do need them completed. If you are having any problems completing them, then do get in touch with us on 01635 791 301 or hello@totalhealthwestberks.co.uk.
Am I guaranteed to get the diagnosis I want?
No. You are paying for an assessment, not for a guaranteed diagnosis. We understand how important this can feel, and our team will always explain the results with care and recommend the next steps that are right for you.
Do I need to get my Summary Care Record (SCR)?
Your summary care record gives our assessors important information about your medical history. Without it, we may not be able to assess you fully.
How long does a ADHD assessment take?
- The ADI-R assessment takes 2 hours to complete.
- The ADOS assessment takes about an hour to complete.
You can take breaks throughout the assessment, and you can have someone with you during the assessment if you wish.
Is the assessment face to face or online?
You can choose to have the assessment online through our secure appointment system or face-to-face at our Private Health Clinic in Thatcham.
What is the cost of an Autism Assessment?
The cost of an Autism Assessment is £2,300
Can I access these assessments via the NHS Right to Choose?
No, these assessments are entirely self funded.
Will the assessments be accepted by the NHS ?
The assessments we offer follow NICE Guidelines as best we can. It is up to your individual GP or NHS clinician whether they accept the assessment and diagnosis from it.
