For many families across the UK, the journey to an autism diagnosis can feel like an uphill battle. In 2026, NHS waiting times for autism assessments remain one of the most pressing concerns for parents, carers, and autistic adults seeking answers.
How long are families waiting?
Current NHS data indicates that many families are waiting between 2 and 5 years for a formal autism assessment, with some areas of England reporting waits of over 5 years. The situation is particularly acute for girls and women, who are frequently under-identified due to diagnostic criteria historically developed around male presentations of autism.
Why are waiting times so long?
Several factors contribute to the backlog. Demand for assessments has risen significantly as awareness of autism has grown. At the same time, there is a shortage of trained clinicians able to carry out assessments, and NHS funding has not kept pace with need. The COVID-19 pandemic created a significant backlog that services are still working through.
What can families do while they wait?
Waiting for a diagnosis does not mean waiting for support. Here are some practical steps families can take:
- Request a SEND support plan at school — schools can put support in place without a formal diagnosis.
- Contact your local SENDIASS (Special Educational Needs and Disabilities Information, Advice and Support Service) for free, impartial guidance.
- Connect with community organisations like Shine Through Autism for peer support, workshops, and practical resources.
- Keep a record of your child's needs, behaviours, and any professional observations — this will be valuable when the assessment does take place.
- Ask your GP about a private assessment if you are in a position to consider this, and ensure any private diagnosis is shared with the NHS.
Advocacy and change
Organisations across the UK are calling on the government to invest in autism assessment services and reduce waiting times. The National Autistic Society and other charities continue to lobby for systemic change. At Shine Through Autism, we believe every family deserves timely, compassionate support — and we are committed to standing alongside you while you wait and beyond.
