Adult Autism Assessments – What to Expect | UK-Wide Neuro-Affirmative Diagnosis
At Affirming Autism, we provide compassionate, neuro-affirmative adult autism assessments that are inclusive, respectful, and tailored to your individual experiences. Our team specialises in diagnosing autism in adults, including those who may have been overlooked or misdiagnosed in childhood—such as women, non-binary people, and those who mask.
Whether you're exploring a possible late autism diagnosis or seeking clarity around your identity, we’re here to guide you through the process with care and understanding.
Is an Autism Assessment Right for You?
Many of our clients seek an assessment because they:
· Have always felt “different” or misunderstood
· Mask their true selves in social or professional settings
· Experience sensory sensitivities or burnout
· Want clarity, community, and self-validation
If this sounds like you, you’re not alone—and you don’t have to navigate this journey without support.

Unsure about proceeding with a full diagnostic assessment?
Why not book a screening assessment to help you decide?
If you later decide to proceed with a full diagnostic assessment through us, the cost of this screening will be deducted from the total.

Neuro-affirmative autism approach: We understand the unique needs of every individual and provide empathetic support tailored to each person's life experience.
What Is Masking? Many autistic people learn to “mask” — hiding their natural traits to fit in. It’s draining, often misunderstood, and can delay diagnosis.
Masking can come at a high emotional cost, often leading to anxiety and burnout.
At Affirming Autism, we see beyond the mask. Our assessments are neuro-affirmative and sensitive to the ways masking can shape your experience. You deserve to be understood for who you are — not just how you appear.

What Is an Adult Autism Assessment?
An adult autism assessment is a process used to determine whether an individual meets the criteria for Autism. Many adults seek assessments later in life after recognising lifelong patterns related to social communication, sensory sensitivity, and routine-focused thinking. A formal diagnosis can offer self-understanding, validation, and access to appropriate support and accommodations.
We offer UK-wide autism assessments online and in person, with flexible appointment times and a neuro-affirmative approach at every step.
