Verified professionals: NHS Compliant Neuro-Affirmative Autism Assessments by Specialists
Our Approach
We honour autistic communication, thinking styles, and lived experience. No pathologising language. No judgement. No pressure.
Why Our Team Stands Out
- We listen first
Your lived experience matters more than ticking boxes. - We understand masking
We recognise subtle signs that traditional assessments often miss. - We value your identity
Autism is not a deficit - it’s a neurotype. - We support you beyond the diagnosis
You will receive a detailed report, guidance on next steps, workplace adjustments and self‑advocacy.
Trauma informed
We understand how trauma, masking, and chronic invalidation can shape how autism presents in adulthood.
NICE compliant
All assessments follow NICE guidelines and are recognised by NHS services, employers, and universities.

Many of our clients have been overlooked for years. We specialise in recognising subtle, internalised, or camouflaged autistic traits.
