The wait times for autism assessments in the UK can vary significantly depending on several factors. Based on data available from October 2024:
NHS Autism Assessment Wait Times in the UK
For Adults:
- National average: 18-24 months
- Range: Some regions report waits of 1-2 years, while others can exceed 3-4 years
- Urban v rural areas: Urban areas typically have shorter wait times than rural areas
- Regional variation: Significant differences exist between NHS trusts / Clinical Commissioning Groups
For Children:
- National average: 12-24+ months
- Range: Some areas report waits of 6-12 months, while others can exceed 3 years

Private Autism Assessment Options
If you’re able to pay, private options are available:
- Average wait: 2 weeks to 3 months
- Cost range: £1,500-£3,000 for a comprehensive assessment
- Availability: Options are available across the country
Factors Affecting Wait Times
Several factors contribute to these wait times:
- Increased awareness and demand for assessments
- Dramatic growth in referrals meaning services might be stretched
- Limited specialist resources and funding constraints
- Geographic location and local service capacity
- COVID-19 created significant backlogs that many services are still working through
- Complexity of individual cases may affect prioritisation
Many NHS trusts have implemented triage systems to prioritise cases based on need, which can affect where you’re placed on waiting lists.
Wait times for ADHD assessments in the UK can vary considerably, but they tend to be somewhat shorter than autism assessment waits in many regions. Here’s what the current landscape looks like based on data available through my knowledge cutoff (October 2024):

Urban v rural area: Generally shorter in urban areas with more specialist services
For Children:

Factors Affecting ADHD Assessment Wait Times
- Significant increase in ADHD assessment requests in recent years
- Limited specialist capacity and funding constraints
- Regional differences in service provision
- COVID-19 pandemic created backlogs that many services are still addressing
- Referral pathways may vary (some areas require GP referral, others accept self-referral)
- Complexity of cases (co-occurring conditions may affect assessment routes)
Some NHS trusts have implemented innovative approaches to reduce wait times, including group assessment processes, screening questionnaires to prioritise cases, and partnerships with independent specialist providers.
