Autism ADHD Waiting List UK: What to Do While You Wait

The autism ADHD waiting list in the UK is one of the biggest challenges facing families of neurodivergent children today. If your child has been referred for an assessment and you are now stuck waiting — sometimes for years — this guide is for you.

You can see that your child is struggling. They may be falling behind at school, becoming increasingly anxious, or finding friendships and daily routines very difficult. Yet every time you try to move things forward, you are met with the same answer: wait. Long waiting times, confusing letters, unanswered calls, and no clear idea of when help will arrive.

This guide will explain exactly how long families are currently waiting on the autism ADHD waiting list in the UK, why the lists have grown so long, and — most importantly — what you can do right now to support your child. There is far more help available than most parents realise, and you do not need a formal diagnosis to access much of it.

How Long Is the Autism ADHD Waiting List in the UK Right Now?

The honest answer is: a very long time — and it varies significantly depending on where you live.

For autism assessments, NHS England data from December 2025 showed that there were over 254,000 children and adults with an open referral waiting to be seen. Of those, more than 90% had already been waiting longer than 13 weeks — the maximum waiting time recommended by the National Institute for Health and Care Excellence (NICE). In Birmingham, children are currently waiting at least 32 months — nearly three years — from referral to diagnosis.

For ADHD assessments, the situation is equally difficult. According to the House of Commons Library, as of December 2025 there were around 562,450 open referrals for ADHD assessment across England. Around two thirds of children on the ADHD waiting list had been waiting for over a year. In some parts of the country, families have been told waits could stretch to ten years.

These are hard statistics to read when you are in the middle of the wait. But knowing the true picture means you can stop waiting passively and start accessing the support that exists right now — before any diagnosis arrives.

Why Is the Autism ADHD Waiting List in the UK So Long?

Understanding why the autism ADHD waiting list in the UK has grown so dramatically can help parents feel less alone and more informed when advocating for their child.

More families are seeking help. Greater public awareness — through schools, social media, and wider conversations about neurodiversity — means more parents are recognising the signs of autism and ADHD earlier and coming forward for assessment. This is a positive development, but NHS services were simply not built to cope with such a sharp rise in referrals.

There are not enough trained specialists. There is a significant shortage of paediatricians, clinical psychologists, and CAMHS (Child and Adolescent Mental Health Services) professionals qualified to carry out neurodevelopmental assessments. Training takes years, and recruitment has not kept pace with demand.

Girls are being recognised later than they should be. Autism and ADHD present differently in girls, which means many went undiagnosed for years. As awareness has improved, more girls are now being referred — rightly so — but this adds further pressure to already stretched services.

The Children’s Commissioner for England has described the situation as a crisis, warning that children’s unmet needs can escalate dangerously when support is delayed. The Government has acknowledged the problem and funded programmes such as the Partnerships for Inclusion of Neurodiversity in Schools (PINS), but many families remain in a very long queue.

The Single Most Important Thing to Know

You do not need a formal diagnosis to get support for your child.

This is the most important sentence in this entire article. Many parents put their lives on hold while waiting for the autism ADHD waiting list in the UK to move — not realising that schools, local authorities, and charities can and should act based on their child’s needs right now, not a diagnostic label.

Your child’s school has a legal duty under the Children and Families Act 2014 to make reasonable adjustments for any pupil who is struggling, diagnosis or not. The person to speak to is your child’s SENCo — the Special Educational Needs Coordinator. Every school in England must have one.

You can also begin applying for an Education, Health and Care Plan (EHCP) — a legally binding document that sets out your child’s needs and the support they must receive — without a diagnosis. What matters is the impact of your child’s difficulties on their daily life.

Step 1: Talk to Your Child’s School SENCo Today

The first practical step while you wait on the autism ADHD waiting list in the UK is to book a meeting with your child’s school SENCo as soon as possible.

Explain what you are seeing at home and ask them to share what the school is observing. Request that your child is added to the school’s SEN register and that a written support plan is put in place immediately. Schools can make a range of adjustments without waiting for a diagnosis, including:

• Extra time in tests and exams
• A quiet space for working or eating lunch
• Visual timetables and adapted instructions
• A trusted key adult to check in with each day
• Access to a calm, low-sensory area when feeling overwhelmed
• Smaller group or one-to-one support sessions

If your school is not responding, or the support on offer is not enough, contact your local SENDIASS (Special Educational Needs and Disabilities Information, Advice and Support Service). Every local authority in England has a SENDIASS, and their advice to parents is completely free and impartial. Find yours through the Council for Disabled Children.

Step 2: Use Your NHS Right to Choose

Many parents stuck on the autism ADHD waiting list in the UK do not know that they have a legal right to choose their NHS assessment provider — and that this right extends to children.

Under the NHS Right to Choose scheme, if your GP agrees that a neurodevelopmental assessment is clinically appropriate, you can ask to be referred to any NHS-approved provider in England — not just your nearest local service. Some Right to Choose providers have considerably shorter waiting times.

Here is how to use it:

1. Visit your GP and ask for a referral for an autism or ADHD assessment.
2. Say you want to use Right to Choose. Tell your GP you would like to choose the provider.
3. Compare waiting times. ADHD UK publishes up-to-date waiting times for all Right to Choose providers across England — check this before your GP appointment.
4. The GP sends the referral. No special funding approval is needed, as long as the provider holds an NHS contract.

Be aware that some local NHS Integrated Care Boards (ICBs) have placed temporary restrictions on Right to Choose due to funding pressures. Your GP should be able to tell you what is currently available in your area. You can also read more on the NHS website.

Step 3: Ask Your GP for Support Right Now

While you are on the autism ADHD waiting list in the UK, your GP can help in several practical ways — without waiting for the assessment to complete.

Ask your GP about:

• A referral to CAMHS (Child and Adolescent Mental Health Services) for anxiety, emotional dysregulation, or low mood — no diagnosis is required for this referral
• A referral to a speech and language therapist if your child has communication difficulties
• A referral to an occupational therapist for sensory sensitivities or difficulties with everyday tasks
• Advice on managing sleep difficulties, which are extremely common in autistic and ADHD children

Do not wait. If your child is struggling with their mental health, anxiety, or school attendance, these are issues that deserve attention in their own right — separate from the neurodevelopmental assessment pathway.

Step 4: Request a Social Care Assessment

This step is one that many parents overlook entirely while waiting on the autism ADHD waiting list in the UK.

You can contact your local authority’s children’s services department and request a Children’s Needs Assessment. This is separate from the NHS pathway and does not require a diagnosis. A social care assessment looks at your child’s needs and your family’s capacity to meet them. If support is identified, the local authority has a legal duty to provide it.

This support might include short break services, family support workers, or access to specialist holiday and play schemes. You can make this request yourself, or ask a professional involved in your child’s care — such as a teacher or health visitor — to refer on your behalf.

Step 5: Look Into Financial Support

Being on the autism ADHD waiting list in the UK can bring significant additional costs — specialist equipment, therapies, tutoring, and adaptations to daily life. Many families are not aware of the financial help they are entitled to.

Disability Living Allowance (DLA) is available for children under 16 who have difficulties with personal care or mobility. Crucially, you do not need a formal diagnosis to claim — eligibility is based on the impact of your child’s condition on their daily life. Apply at GOV.UK — Disability Living Allowance for Children.

Carer’s Allowance may be available if you spend at least 35 hours a week caring for your child and they receive the middle or higher rate care component of DLA. Find out more at GOV.UK — Carer’s Allowance.

You may also qualify for a Carer’s Assessment from your local authority, which can open the door to additional practical support for you as a parent.

Step 6: Connect With Other Families

One of the most powerful things you can do while on the autism ADHD waiting list in the UK is to connect with other parents who understand what you are going through.

The National Autistic Society has local branches across the UK, an online community, and a Parent to Parent Emotional Support Helpline specifically for parents and carers of autistic children.

ADHD UK is a charity run by people with ADHD, for people with ADHD. Their website has detailed waiting time information, support strategies, and an active community for parents.

Ambitious about Autism supports autistic children, young people, and their families with information, advice, and a range of practical services.

Contact supports families raising disabled children. They run a helpline, local groups, and produce clear, practical guides that are especially useful while you are waiting for a diagnosis.

You can also find your local Parent Carer Forum — groups of parents who have navigated the same system and can share real, local knowledge — through the National Network of Parent Carer Forums.

Step 7: Support Your Child’s Wellbeing at Home

While you wait on the autism ADHD waiting list in the UK, there is a great deal you can do at home to support your child day to day.

Routine and predictability make a real difference for children with autism and ADHD. Visual timetables, consistent daily rhythms, and calm, clear expectations help children feel safe and regulated.

Sensory awareness matters too. Some children are very sensitive to sounds, lights, textures, or smells. Reducing unnecessary sensory input — softer lighting, ear defenders, a quiet corner — can help your child manage better at home and at school. Read our guide on Understanding Sensory Processing for practical ideas.

Positive, strengths-based language is essential. Children who are struggling at school often feel they are failing. Your job is to help your child understand that their brain works differently — not worse — and that there are many remarkable things about how they see and experience the world.

Your own wellbeing matters. Research has consistently shown that parents of neurodivergent children face higher levels of stress and are more at risk of mental health difficulties. Please do not put yourself last. Speak to your GP if you are struggling, accept support when it is offered, and connect with other parents who understand.

What About a Private Assessment?

Some families choose to pay for a private autism or ADHD assessment rather than remain on the NHS waiting list. Private assessments typically take between 2 and 12 weeks and follow the same diagnostic criteria — DSM-5 or ICD-11 — used by the NHS.

Private reports are generally accepted by schools and local authorities for the purposes of EHCP applications and school support. Many families have found that having a private diagnosis in hand has helped them access help much more quickly.

However, there are important considerations. Private assessments vary significantly in cost, and this option is simply not available to every family. If your child is diagnosed with ADHD privately and requires medication, your GP will need to agree to a shared care arrangement for prescribing — and not all GPs will do so.

If you are considering this route, speak to your local National Autistic Society branch or ADHD UK first. They can advise on what to look for in a private provider and what questions to ask.

A Note on What a Diagnosis Really Means

It is worth saying clearly: a diagnosis does not change who your child is.

It can give your family language to describe your child’s experience. It can open doors to specific support, therapies, and benefits. It can help your child understand themselves — and feel far less alone. For many families, a diagnosis brings enormous relief.

But a diagnosis is a tool for understanding, not a measure of potential. Many of the most creative, determined, and remarkable people in the world are neurodivergent. Your child’s future is not defined by how long the autism ADHD waiting list in the UK takes to move.

In the meantime, your child needs your love, your understanding, and your advocacy. None of those things require a letter from a consultant.
