What the latest NHS waiting-time reports mean for adults seeking ADHD or autism assessment, and what you can do while waiting.
A September 2026 Guardian investigation reported that some NHS bodies in England have introduced minimum waits of up to two years for certain ADHD and autism assessment pathways. This doesn’t mean everyone will wait two years, but it highlights the pressure on services. If you’re waiting for answers, there are still steps you can take to access support, understand your options and prepare for a thorough assessment.
Perhaps you’ve spent years wondering whether ADHD or autism could explain why certain parts of life seem to take so much more effort than they should. You’ve finally decided to seek an assessment, only to discover that getting an appointment could take years.
For many adults recognising ADHD or autistic traits later in life, this isn’t simply about wanting a diagnosis. It’s about understanding experiences that may have followed them through school, work, relationships and family life.
So, what do the latest NHS waiting-time reports actually mean? And what are your options if you’re already waiting?
What’s happening with NHS ADHD and autism waiting times?
On 24 September 2026, The Guardian reported that some NHS bodies in England had introduced minimum waiting periods for ADHD and autism assessments.
According to the investigation, 15 Integrated Care Boards (ICBs), serving around 19 million people, had introduced different measures to manage assessment demand and expenditure.
These included minimum waiting periods, limits on funded assessments and clinical prioritisation systems.
For context, an ICB is the NHS organisation responsible for planning and funding healthcare services within a particular area of England.
The reported restrictions vary considerably. For example:
- West Yorkshire: a two-year minimum wait from referral for ADHD or autism assessment with an independent provider.
- North East and North Cumbria: approximately 78 weeks for an initial assessment through funded private providers.
- Somerset: a reported minimum wait of 52 weeks.
- Devon: a reported minimum wait of 14 weeks.
These are examples of specific local arrangements reported by The Guardian, not standard waiting times for every NHS patient.
And that’s an important distinction.
Your own waiting time depends on where you live, the service you’ve been referred to and the assessment pathway available to you.
How many people are waiting for ADHD or autism assessments?
The latest published NHS England figures give some indication of just how much demand services are experiencing.
Its August 2026 ADHD Management Information reported:
- Up to 959,662 open referrals that may have been for ADHD assessment in England in June 2026.
- Up to 37,105 new referrals to mental health services for possible ADHD assessment during that month.
It’s worth explaining that the first figure counts referrals that may relate to ADHD assessment. It isn’t a confirmed count of individual adults waiting for diagnosis.
For autism, NHS England recorded 294,792 patients with an open referral for suspected autism in June 2026.
That autism figure also needs some context: NHS England identified a missing provider submission affecting the June data, so it shouldn’t be interpreted as a complete count of everyone awaiting assessment.
Behind those statistics are people trying to understand themselves and access the right support.
And for someone who’s already been struggling for years, being told that an assessment could still be a long way off can be particularly difficult.
Why are more adults seeking ADHD and autism assessments?
One important reason is that our understanding of ADHD and autism has changed.
For a long time, ADHD was commonly associated with visibly hyperactive children. Autism was also understood through a much narrower range of presentations.
As a result, many adults grew up without anyone recognising what they were experiencing.
You might have done well academically but struggled privately with organisation, time management or completing everyday tasks.
You might have built a successful career while constantly feeling overwhelmed by the social and sensory demands around you.
Or perhaps you’ve developed such effective ways of compensating that nobody sees how much effort everyday life requires.
Some adults only begin exploring ADHD or autism after a significant life change:
- a promotion or increased responsibilities at work
- becoming a parent
- experiencing burnout
- navigating perimenopause
- recognising similar traits following a family member’s diagnosis
Increased awareness means more people are recognising experiences that previously went unexplained.
Of course, recognising ADHD or autistic traits doesn’t automatically mean someone will receive a diagnosis. Other conditions or circumstances can sometimes explain similar experiences.
That’s precisely why proper clinical assessment matters.
What does waiting two years actually mean for someone seeking an assessment?
Two years might sound like another healthcare statistic, but life doesn’t stop while you’re waiting.
Imagine an adult who’s always managed work by staying late, relying on last-minute pressure and keeping endless lists to remember what needs doing.
From the outside, they’re managing perfectly well.
But perhaps they’ve recently taken on a more demanding role. Their usual strategies aren’t working anymore, and they’re finding it increasingly difficult to keep up.
They begin wondering whether ADHD could explain experiences they’ve had since childhood.
Now imagine being told they may need to wait another two years for an assessment.
For someone else, the difficulty might be sensory overwhelm, navigating social expectations or feeling completely exhausted after a normal working day.
They’re wondering whether they might be autistic, but they don’t yet have the clinical clarity to understand what’s happening.
Not everybody waiting for assessment will experience these difficulties, and diagnosis isn’t a solution to everything.
But access to a proper assessment can help people understand their experiences and identify appropriate next steps.
Our article on late diagnosis of ADHD and autism in adults explores why that understanding can be particularly meaningful later in life.
Does a shorter waiting time mean a less thorough assessment?
No. The length of time someone waits for an appointment and the quality of the assessment itself are two different things.
Whether an assessment is NHS-funded or private, it should be carried out by an appropriately qualified clinician and gather enough evidence to reach a reliable clinical conclusion.
For ADHD, this should include exploring your experiences now, your developmental history, the impact on everyday life and whether anything else could explain your difficulties.
Autism assessment also requires a comprehensive understanding of your development, communication, social experiences, sensory differences and relevant clinical history.
NICE guidance for ADHD specifically advises against making a diagnosis using rating scales alone. Its guidance for adult autism assessment also emphasises comprehensive clinical evaluation.
That’s why choosing an assessment provider should involve more than checking who has the next available appointment.
What should you ask before booking an assessment?
Whether you’re considering an NHS-funded or self-funded assessment, these questions can help:
- Who will conduct my assessment, and what are their qualifications?
- What information will I need to provide beforehand?
- Will the assessment explore my developmental history?
- Will other possible explanations for my experiences be considered?
- What happens if I don’t meet the diagnostic criteria?
- Will I receive a detailed written report?
- What support is available after the assessment?
- If ADHD medication is recommended, how is ongoing treatment managed?
A credible provider should be able to explain its process clearly.
And a good assessment isn’t one that guarantees you’ll receive a diagnosis. It’s one that helps you understand what’s actually going on.
What can you do while waiting for an NHS ADHD or autism assessment?
If private assessment isn’t an option, or you’d prefer to remain on an NHS pathway, that doesn’t mean you have to put everything else on hold.
There are several practical steps worth considering.
1. Ask about your current referral
Contact your GP or the relevant assessment service to clarify where your referral currently stands.
Ask whether the service can provide an estimated waiting time and what happens after the initial assessment.
If you live in England, you can also ask your GP about your eligibility for Right to Choose, which may allow referral to a qualifying NHS-contracted provider.
Check the full pathway, including current waiting times, funding arrangements and post-diagnostic support, rather than assuming another provider will automatically offer a shorter wait.
2. Seek help with difficulties you’re experiencing now
You don’t necessarily need to wait for an ADHD or autism diagnosis before receiving help with other concerns.
If you’re experiencing anxiety, depression, persistent sleep difficulties or other health problems, speak to your GP about the support available now.
Those concerns deserve attention in their own right.
3. Ask about workplace adjustments
If you’re struggling at work, consider speaking to your employer about the practical changes that might help.
Depending on your circumstances, examples might include:
- written instructions instead of relying entirely on verbal information
- a quieter working environment
- clearer priorities and deadlines
- regular check-ins with your manager
- adjustments to communication or working arrangements
You don’t necessarily need to wait for a formal diagnosis before discussing your needs. Legal responsibilities will depend on your individual circumstances.
4. Keep a record of your experiences
You don’t need to create a complicated symptom diary.
Simply note down real examples of what you’re finding difficult, when it happens and how it affects you.
Think about work, relationships, routines, organisation, sensory experiences or situations that leave you particularly overwhelmed.
These examples can help you explain your experiences more clearly when your assessment appointment arrives.
Should you consider a private ADHD or autism assessment?
For some adults, the prospect of waiting several more years makes private assessment worth exploring.
It’s a personal decision, and self-funded assessment won’t be financially realistic for everybody.
The main consideration should be whether the provider offers a thorough assessment, qualified clinicians and clear guidance about what happens afterwards.
At The ADHD & Autism Clinic, our private adult ADHD assessments and private adult autism assessments are structured to build a detailed understanding of each person’s experiences.
That means taking developmental history seriously, exploring current difficulties and considering other relevant explanations before reaching a clinical conclusion.
If you’re comparing providers, it’s also important to understand the complete cost of assessment and any ongoing treatment. A private diagnosis doesn’t automatically mean subsequent medication or care will transfer to the NHS.

Frequently asked questions
Is everyone now facing a two-year NHS ADHD or autism wait?
No. The September 2026 Guardian investigation reported minimum waits of up to two years for certain assessment pathways in some areas of England. Waiting times and referral arrangements vary between NHS services. Ask your GP or current provider for information about the arrangements that apply to your referral.
Can I get support before receiving an ADHD or autism diagnosis?
Yes. You can speak to your GP about difficulties you’re experiencing now, including anxiety, sleep problems or other health concerns. You may also be able to discuss practical adjustments at work or in education. You don’t have to postpone every form of support until your assessment is complete.
Is a private ADHD or autism diagnosis as thorough as an NHS diagnosis?
A thorough assessment should meet appropriate clinical standards regardless of how it’s funded. What’s important is the clinician’s qualifications, the assessment process, the evidence considered and the quality of the final report. Private assessment should never mean paying for a guaranteed diagnosis or bypassing proper clinical evaluation.
What happens if my assessment doesn’t result in a diagnosis?
Your clinician should explain their findings and why the diagnostic criteria weren’t met. This may involve discussing other explanations for your experiences or recommending further assessment or support. A clinically useful assessment should provide meaningful guidance even when the outcome isn’t an ADHD or autism diagnosis.
Getting answers shouldn’t mean compromising on assessment quality
The latest NHS waiting-time reports highlight how difficult accessing an ADHD or autism assessment has become for many people.
But behind every referral is someone with their own experiences, circumstances and reasons for wanting answers.
For some, it’s about understanding a lifetime of unexplained differences. For others, it’s about finding appropriate support at a point when their existing ways of coping are becoming harder to maintain.
Whatever route you choose, an assessment should give you more than a diagnostic label. It should offer a careful clinical explanation, an opportunity to ask questions and meaningful recommendations about what comes next.
