Adult Autism Assessment
Our adult autism assessments are for people aged 18 and above who are considering whether they may be autistic. We recognise that many people come to assessment later in life, often after years of uncertainty, and aim to provide a clear, thoughtful and well-structured process.

Unique Experiences
About autism
Many adults who seek an autism assessment describe feeling different for a long time without fully understanding why. Over time, people may develop ways of adapting socially, sometimes described as masking or camouflaging.
Autism in adulthood can present differently from childhood, particularly for those who were not identified earlier. Experiences can also vary across individuals, including across gender, communication style and life context.
Understanding your experiences through the lens of autism can help make sense of long-standing patterns and support more informed decisions about what might be helpful going forward.
Common Experiences in Adults
- Feeling exhausted after social situations, even when enjoyable
- Finding it difficult to maintain friendships despite wanting connection
- Preferring deeper conversations over small talk
- Needing time to recover after busy or social days
- Having strong interests with a high level of focus or engagement
- Finding unwritten social rules unclear
- Sensory sensitivities (for example to sound, light, textures or smell)
- Preferring routines and finding unexpected changes difficult
- Taking things literally or missing implied meaning
- Feeling as though you are “performing” in social situations
What sets us apart
Timely access without compromising care
NHS waiting times for assessment are often long. Our pathway, from initial contact to final report, typically takes around 6 to 8 weeks. This is achieved through clear processes and efficient systems, while maintaining the depth and quality of assessment.
Integrative team approach
NICE guidelines recommend a multidisciplinary assessment. Each case within our service is reviewed through a clinical panel, bringing together different professional perspectives. Additional input from speech and language therapy or other disciplines is included where helpful.

Where assessment fits in your journey
A specialist adult autism assessment sits between initial exploration and ongoing support. Some adults come straight here; others start with Initial Support to talk things through first.
Initial Support
Not sure if assessment is the right next step? Our Initial Support sessions offer practical, neurodiversity-informed guidance with no commitment to a full pathway.
Adult Autism Assessment
A relaxed adult autism evaluation using ADOS-2 and structured developmental interview, delivered by our multi-disciplinary team — with a clear, plain-English report.
Post-Diagnostic Support
Diagnosis is a starting point, not a destination. Make sense of your identity through 1:1 programmes, small group cohorts, or flexible pay-as-you-go sessions.
