If you are Autistic, waiting for an assessment, or supporting an Autistic child, you have probably seen the headlines. People “incentivised” to get diagnoses, an overdiagnosis crisis, a government review questioning whether autism and ADHD is being handed out too freely.
It is unsettling reading, and a lot of it is framing rather than fact. This piece is not about who is right in that argument, instead I want to ask something more useful; what is actually happening, what could realistically change, and what it means in practice for your assessment, your benefits, your child’s school place, and your job.
What Is Actually Happening
In December 2025, the Department of Health and Social Care commissioned an independent review into the prevalence of, and support for, mental health conditions, ADHD, and autism. Professor Peter Fonagy chairs it, with Professor Sir Simon Wessely and Professor Gillian Baird as vice-chairs. An interim report was published on GOV.UK in June 2026, and a final report is expected during 2026.
The terms of reference ask the review to look at the factors behind trends in prevalence, the impact of clinical practice including “the risks and benefits of medicalisation”, prevention and early intervention, and different models of support both within and beyond the NHS.
Running alongside it is the Timms Review; the first full review of Personal Independence Payment since PIP was introduced. It reports to the Secretary of State in autumn 2026. The two are connected, with findings from the health review expected to feed into the benefits review.
That connection is the reason this matters practically rather than just intellectually. A debate about diagnostic thresholds in a medical journal is limited in the scope of immediate change that it precipitates. A debate about diagnostic thresholds that lands on the desk of a benefits review three months before eligibility rules are rewritten is a different thing entirely.
What The Interim Report Actually Said
On common mental health conditions (mainly anxiety and depression) the review found evidence of a real increase in population prevalence over the past two decades, particularly among younger people. Prevalence among 16 to 64 year olds rose from around 15.5% in 1993 to around 22.6% in 2023-24.
On autism and ADHD, it found something different. The best population data suggests underlying prevalence has been relatively stable, while diagnoses and referrals have risen dramatically. Thirteen times more people were waiting for an autism assessment in September 2025 than in April 2019.
Critically, the review did not conclude from this that the extra diagnoses are false. It said several processes are likely operating at once;
- Genuine changes in distress
- Better recognition of need that was previously missed
- Changes in help-seeking
- Changes in professional and public understanding
- Institutional incentives attached to holding a diagnosis.
That last item is what the press picked up, but it is one factor in a list, and it describes a system problem, not a patient problem. If support is only available to people with a diagnosis, people will pursue a diagnosis, that is the system working exactly as designed.
This is also consistent with the existing research. A UK cohort study found a 787% increase in recorded autism diagnoses between 1998 and 2018, with the sharpest rises among adults and among women and girls, the groups historically missed. A separate Lancet Regional Health (Europe) study of GP records in England concluded that Autistic adults remain substantially underdiagnosed and that policies aimed at fixing this have not yet worked. Both findings can be true at once; recorded diagnoses rising steeply, and a large number of Autistic people still undiagnosed.
The interim report’s own direction of travel is towards a system that is, in Fonagy’s phrase, “more proportionate, more responsive and less dependent on diagnosis alone.”
Where The Risk Sits
Needs-led support instead of diagnosis-gated support is, on its face, what most Autistic advocates have wanted for years. A diagnosis should not be the turnstile you have to pass through to get a quiet room, a later start time, or help with paperwork.
The concern raised by organisations across the sector is about sequencing and framing. Removing the diagnostic gate is good if you build the support first, removing it while questioning whether the diagnoses were valid, during a period of pressure on welfare spending, produces fewer routes in, and less legitimacy for the people already through the door.
That is the thing to watch. Not “will they abolish autism” (they will not) but whether support arrives before the gate is narrowed.
Five Practical Areas, And What Could Actually Change
1. Getting an assessment
This is where pressure is already visible, and it predates the review.
As of March 2026 there were 270,701 people with an open referral for suspected autism in England, and around 90% had been waiting longer than the 13 weeks NICE recommends. Right to Choose (the mechanism that lets you ask for referral to any qualifying provider with an NHS contract) has been restricted in practice by a growing number of Integrated Care Boards since 2024, through capped provider panels, prior-approval requirements and GP guidance discouraging its use.
Legally, ICBs cannot abolish Right to Choose by policy; the NHS Standard Contract still requires them to comply with patient choice obligations. In practice, availability varies enormously depending on where you live.
Some areas are also moving to needs-led models. Greater Manchester introduced a new model of care from January 2026 focused on getting people support based on individual need rather than diagnosis alone, with coaching, peer groups and self-help offered while people wait.
What this means for you: if you are considering an assessment, the practical case for starting the process sooner rather than later is stronger than it was a year ago, not because diagnosis is about to disappear, but because routes in are being narrowed locally and the waiting lists are long. Check your own ICB’s current Right to Choose position rather than assuming national guidance applies to you.
2. PIP and benefits
The proposal to require four or more points in a single daily living activity was dropped after significant opposition, but the powers may still be applied to new claimants from November 2026, once the Timms Review reports.
The picture on who is affected is genuinely mixed, and it is worth considering both halves. DWP’s own analysis suggested that people with physical conditions such as back pain and arthritis would be most affected by the four-point change, and that people with learning disabilities, autism and ADHD would be least likely to be affected (because Autistic claimants often score across several activities rather than heavily in one). Disability organisations counter that this is precisely the risk; people who need low-to-moderate support across many areas are exactly the group a threshold rule can catch out, depending on how it is drawn.
Separately, PIP caseload figures show roughly 100,000 additional claimants receiving PIP for conditions including autism and ADHD, and senior ministers have signalled that eligibility rules for these conditions are likely to be reworked.
What this means for you: PIP has always been assessed on functional impact, not on diagnosis. A diagnosis alone has never qualified anyone, and its absence has never automatically disqualified anyone. That will not change, what may change is the threshold. If you claim PIP, the most valuable thing you can do this year is keep a contemporaneous record of the support you actually need; what a bad day looks like, what you cannot do reliably, what help you receive from others, how often. Evidence about function is what survives a rule change, evidence about labels does not.
3. School, EHCPs and SEND
Two things are happening in parallel here, and it is easy to conflate them.
The Schools White Paper, “Every Child Achieving and Thriving”, was published in February 2026 and consulted until May, proposing significant reform to EHCPs and the SEND Tribunal. Nothing in it has changed the law yet, and the government’s stated position is that no changes to support received through EHCPs would take effect before at least September 2030. The National Autistic Society has raised concern that reforms to EHCPs and the Tribunal could leave Autistic young people without the right school place, since for some children a specialist setting is the only workable option regardless of how much mainstream inclusion improves.
The overdiagnosis review intersects with this because it is expected to inform SEND reform.
What this means for you: an EHCP is legally a needs-based document, not a diagnosis-based one. A child does not need an autism diagnosis to be assessed for one, and never has. In practice a diagnosis often unlocks the process faster, which is exactly the incentive problem the review identified. If your child has an EHCP, it remains in force and remains legally enforceable. If you are seeking one, the request should be built around evidence of need (what is not working in the current setting, what has been tried, what the impact has been) because that is what the law actually tests.
4. Work
Least likely to be affected, and but worth saying.
Under the Equality Act 2010, you are disabled if you have a physical or mental impairment with a substantial and long-term adverse effect on your ability to carry out normal day-to-day activities for 12 months or more. That definition contains no requirement for a formal diagnosis. Your employer’s duty to make reasonable adjustments is triggered by knowledge of the impairment and its effects, not by a diagnostic letter.
Access to Work does not strictly require a formal diagnosis either. You can apply while waiting for an assessment and add the report when it arrives.
What this means for you: if you are waiting for an assessment, you are not required to wait before requesting adjustments. Make the request in writing, describe the barrier and the adjustment rather than leading with the label, and keep the correspondence. Nothing in the current reviews touches the Equality Act.
5. The question underneath
For a lot of people, the sharpest part of this is the experience of watching a national conversation query whether your diagnosis (often obtained after years of struggle and a long wait) was real.
That is a reasonable thing to find distressing, and we should not try to be reasoning past it. It is also worth being precise about what has and has not been said. The review’s own finding is that underlying prevalence has been broadly stable while recognition has improved. Being recognised later than you should have been is not the same as being diagnosed wrongly.
What to do in the next few months
- If you are waiting for an assessment: check your ICB’s current Right to Choose position directly, ask your GP what local pathway options exist, and find out whether your area offers pre-diagnostic support.
- If you claim or plan to claim PIP: start or continue a functional diary now. Records made before a rule change are worth more than recollections made after one.
- If you have a child in the SEND system: an existing EHCP remains enforceable. Build any new request around documented need, not diagnosis.
- If you are working: request adjustments in writing now if you need them. Do not wait for an assessment.
- If you want to influence it: the Timms Review has run a call for evidence and a steering group, and the final Fonagy report is still to land. Sector organisations are actively seeking Autistic input.
What to watch for
Three things will tell you which direction this is going.
The final Fonagy report, and specifically whether its recommendations fund alternative support routes or simply recommend fewer diagnoses, the Timms Review in autumn, and whether it applies a threshold rule to new claimants from November, and the SEND reform response, and whether the promised needs-led system arrives with money attached.
The test in every case is the same one. Needs-led support is a genuine improvement if the support exists. If it does not, “less reliance on diagnosis” is just a narrower door with better wording.
