Availability Insights
Private autism assessment availability varies considerably across the UK. Adult autism assessments have seen growing demand in recent years, and waiting times can be longer than for ADHD assessments. Some providers offer remote or hybrid assessment pathways, which can improve access for those outside major cities.
What This Means
If you are waiting for an NHS autism assessment, a private assessment can provide an earlier diagnosis and access to support. Comparing providers across regions and considering remote options may help reduce your waiting time.

Private vs NHS Autism Assessment
Remote Autism Assessments
Some private autism assessment providers offer remote or hybrid pathways, typically involving a video-based interview and remote completion of standardised questionnaires. Not all providers offer fully remote autism assessments, as some assessments benefit from in-person observation. Where remote assessments are available, they can significantly improve access for individuals in areas with limited local provision.
What This Means
Remote autism assessments are not available from all providers. Check each provider profile to confirm whether remote options are offered before making contact.
