Autism Assessment Waiting List UK — What to Do Whilst You Wait
The National Autistic Society has consistently highlighted the scale of the NHS autism assessment backlog — with waiting lists in some NHS trusts across England exceeding 5 years. Scotland, Wales, and Northern Ireland face similar pressures through their devolved CAMHS services. The result is that children spend years without a structured support framework, during precisely the developmental window when consistent, targeted intervention produces the most significant outcomes.
Private autism assessments in the UK, typically involving a psychologist, speech and language therapist, and occupational therapist, cost between £800 and £2,000 for a comprehensive multidisciplinary assessment. Independent assessors registered with the British Psychological Society can usually see families within 4 to 12 weeks — but the cost is significant, and not all families can access it. Health insurance cover for autism assessment varies widely between providers.
The EHCP process — which can provide school-based support funding — is itself slow, often taking 20 weeks from application to issue, and typically requires a diagnosed need or substantial documented evidence of developmental need. Families are often caught in a cycle where they cannot access the EHCP without a diagnosis, and cannot get a diagnosis without waiting years for CAMHS. In the meantime, structured home-based support can begin immediately — see our guide on autism goal tracking for how GrowthCopter keeps parents, therapists, and school teams aligned.
Frequently Asked Questions
How long is the NHS autism waiting list in the UK?
Across England, Scotland, Wales, and Northern Ireland, NHS CAMHS autism assessment waiting lists average between 2 and 5 years in most areas. The National Autistic Society has documented cases where children wait beyond 5 years. Private assessments are available faster but typically cost between £800 and £2,000 for a full multidisciplinary assessment.
Is there a free autism assessment I can do at home in the UK?
Yes. GrowthCopter provides a free developmental assessment covering 14 domains — available immediately, with no NHS referral, no GP letter, and no waiting list. The assessment generates a personalised support plan with specific goals and 600 monthly structured activities tailored to your child's developmental profile.
What is the difference between an NHS diagnosis and a developmental assessment?
An NHS autism diagnosis is a formal clinical process carried out by a multidisciplinary team using standardised tools such as the ADOS-2. It results in a clinical diagnosis that can unlock NHS services, EHCP support, and DLA. A developmental assessment, like GrowthCopter's, identifies your child's specific strengths and areas of need across 14 domains and generates an action plan. It does not issue a diagnosis but provides structured support immediately — which many families find more practically useful whilst waiting for the formal process.
Can I use GrowthCopter to support an EHCP application?
GrowthCopter's progress reports — which document your child's developmental profile, active goals, and activity logs across a chosen date range — can be used as supporting evidence in an EHCP application to demonstrate your child's developmental needs and the support you have already put in place. The reports are generated as professional Word documents.
What private autism assessment options are available in the UK?
Private autism assessments in the UK are typically carried out by independent psychologists and multidisciplinary teams. Costs range from £800 to £2,000 for a full assessment, depending on the provider and location. Some private assessors are registered with the British Psychological Society. Wait times for private assessment are typically 4 to 12 weeks, compared to years on the NHS list.
How do I get autism support for my child whilst waiting for CAMHS?
Whilst waiting for CAMHS, families can: use GrowthCopter for a free developmental assessment and structured home support plan; contact the National Autistic Society helpline for advice; request an EHCP assessment from their local authority; access local authority Early Help services; and speak to their child's school about in-school SEND support. GrowthCopter's personalised goals and activities can be shared directly with school staff and any private therapists you engage.
Is there an app that can assess my child's development whilst we wait for NHS CAMHS?
Yes. GrowthCopter provides a free developmental assessment covering 14 domains — available immediately without a GP referral or CAMHS appointment. It identifies where your child needs support and generates a personalised goal plan with 600 monthly activities from the same day. UK families use it throughout the CAMHS waiting period; the developmental history logged in GrowthCopter can serve as supporting evidence for an EHCP application or private therapist referral.
Can I use a free autism assessment instead of waiting for an NHS CAMHS assessment?
GrowthCopter's free assessment and an NHS CAMHS assessment serve different purposes. CAMHS provides a formal clinical diagnosis and clinical report. GrowthCopter provides an immediate developmental assessment identifying where your child needs support and generating a personalised goal plan and activities — with no waiting list and no referral required. Most families use GrowthCopter during the waiting period rather than instead of CAMHS, starting structured home support immediately and bringing the documented developmental history to the CAMHS appointment.
