Getting an autism diagnosis for your child in 2025 can feel like navigating a broken system. For many families in the UK, it has become a waiting game of months—or even years—just to access the right support. And during that time, children are left without the understanding, interventions, and educational help they desperately need.
The Numbers Behind the Crisis
As of late 2024, over 212,000 people in England were on the NHS autism assessment waiting list. That’s a 23% increase in just one year and a staggering 82% increase since 2022. These figures are not just statistics—they represent children and families stuck in limbo.
The Children’s Commissioner reported that some children are now waiting more than four years for a diagnosis. For those referred through community paediatrics or CAMHS (Child and Adolescent Mental Health Services), two-year wait times are becoming the norm. This is not only unacceptable—it’s harmful.
What This Means for Families
A delayed diagnosis doesn’t just delay a label. It delays everything that comes with it:
- Access to EHCPs (Education, Health and Care Plans)
- Understanding from teachers and schools
- Appropriate educational provision or alternative provision
- Access to therapies such as speech and language, OT, or mental health support
Children who mask their struggles at school are especially vulnerable, as their needs often go unseen until they reach breaking point. Meanwhile, parents are left trying to prove that something is wrong while managing meltdowns, exclusions, and emotional exhaustion.
Why the System Is Struggling
The national autism strategy, introduced in 2021, set out a vision for change. It aimed to improve:
- Early identification
- Diagnostic capacity
- Integration across education, health, and social care
But despite these aims, the system is overwhelmed. Referrals have skyrocketed, while staffing and funding haven’t kept pace. And while the NHS has targets in place (assessments within 13 weeks), only 1 in 10 children are being seen within that window.
What Can You Do If You’re Waiting?
If you’re stuck in the waiting game, here are some practical steps:
1. Apply for an EHCP Anyway
You do not need a formal diagnosis to start the EHCP process. If your child has clear needs that affect their education, you can apply now. Visit AskEllie.co.uk for step-by-step guidance.
2. Gather Evidence
Start keeping a diary of behaviours, school struggles, and medical visits. This builds a timeline and helps professionals understand what you’re dealing with.
3. Speak to School SENCOs
Even without a diagnosis, schools can and should offer SEN support. That could include a key worker, reduced timetable, sensory breaks, or access to a nurture space.
4. Seek Support from Charities
- National Autistic Society
- Autism Central
- Contact (for families of disabled children)
These organisations offer guidance, helplines, workshops, and community support.
5. Push for Interim Support
While waiting, ask your GP or local services for early help, referrals to OT or SLT (speech and language therapy), or CAMHS support for emotional wellbeing.
Final Thoughts
A diagnosis is not a magic wand, but it can open doors. The sad reality is that in 2025, many of those doors are still locked behind long waiting lists and broken systems.
That’s why projects like AskEllie.co.uk were created—to support parents through the gaps. We help you understand your rights, draft EHCP requests, navigate DLA or PIP forms, and challenge unfair decisions. Because while the system may be failing, you don’t have to face it alone.
