Investigation raises serious questions about a system that links medical diagnoses to financial support, as disability claims soar and taxpayers face an increasingly expensive welfare bill.
Britain’s spiralling welfare system is facing fresh scrutiny after a major government-commissioned review warned that the way benefits and public services are allocated may be helping to fuel soaring demand for ADHD and autism diagnoses.
The findings raise uncomfortable questions for Labour, which is already under pressure over the rising cost of sickness and disability benefits, and whether successive governments have created a system that places too much emphasis on medical labels rather than helping people overcome difficulties, develop independence and remain in education or employment.
As reported by The Telegraph on Friday, 9 October, a 607-page review led by Professor Peter Fonagy, a clinical psychologist at University College London, has identified serious concerns about the financial incentives built into Britain’s assessment and support systems.
The report does not suggest that ADHD or autism are invented conditions, nor that people with genuine disabilities should be denied help. It does, however, question whether a system that makes diagnosis the gateway to financial assistance, educational provision and other services is encouraging an ever-growing reliance on medical assessments.
And with Britain’s welfare spending already running into hundreds of billions of pounds annually, the implications extend far beyond the NHS.
DISABILITY CLAIMS SOAR AS DIAGNOSIS BECOMES GATEWAY TO SUPPORT
Figures highlighted by The Telegraph show that the number of disability benefit claimants whose main disabling condition was autism rose from 79,395 in January 2019 to 268,965 in July 2026.
That represents an increase of approximately 239 per cent.
The equivalent figure for ADHD or attention deficit disorder increased from 23,741 to 106,087 over the same period, a rise of approximately 347 per cent.
These are extraordinary increases, although the figures alone cannot establish how much of the growth reflects greater recognition of previously undiagnosed conditions, changes in eligibility or genuine increases in support needs.
The review warns that diagnosis has increasingly become the principal means of obtaining treatment, educational assistance, workplace adjustments, welfare payments and specialist services.
Crucially, it highlights the risk that linking assessments directly to financial entitlements can encourage applicants to emphasise their difficulties rather than their abilities.
Personal Independence Payment (PIP) assessments and work capability assessments are specifically identified as examples of systems where financial entitlement can influence how individuals present their circumstances.
This is a fundamental problem for policymakers.
A welfare system should provide a safety net for those who genuinely need it. It should not create incentives that make a diagnosis more valuable than recovery, resilience or independence.
Nor should it leave families believing that obtaining a medical label is the only reliable route to securing help for their children.
WARNING THAT CHILDREN RISK BEING DEFINED BY DIAGNOSES
The review also raises concerns about the long-term consequences of unnecessary medical diagnoses, particularly among children.
Recorded ADHD prevalence among teenage boys has increased almost 13-fold since 2000, while recorded autism prevalence in the same group has risen more than 23-fold.
Among boys aged six to 11, recorded autism prevalence increased from 0.4 per cent to 6.3 per cent between 2000 and 2025.
Professor Sir Simon Wessely, of King’s College London, who served as vice-chairman of the review, warned that continuing trends could result in overdiagnosis and excessive medicalisation.
The concern is that children may come to see a diagnosis as the defining feature of their identity, potentially lowering expectations of what they can achieve.
That is not an argument against recognising genuine neurodevelopmental conditions. Proper diagnosis and appropriate treatment can transform lives.
But there is a difference between identifying a difficulty so that somebody can overcome barriers, and creating a culture in which individuals are encouraged to regard themselves primarily through the limitations recorded on an assessment form.
Britain should be raising aspirations among its young people, not allowing bureaucracy to determine their ambitions.
BRITAIN’S WELFARE BILL HEADING TOWARDS £400 BILLION
The findings come against the backdrop of an enormous and growing welfare bill.
According to the Office for Budget Responsibility’s November 2025 forecasts, spending on disability benefits alone was expected to rise from £41.4 billion in 2024-25 to £65.3 billion by 2030-31.
That is an increase of almost £24 billion in just six years.
Meanwhile, wider welfare expenditure reached an estimated £329.1 billion in 2025-26 and is forecast to exceed £400 billion by the end of the decade.
These figures include the state pension, which accounts for a substantial proportion of total welfare spending, but the particularly rapid growth in working-age sickness and disability claims has become a major concern for the public finances.
The political question is becoming increasingly difficult for Labour to avoid: how much longer can taxpayers be expected to fund a system whose costs continue to rise, without ministers addressing the incentives driving that growth?
Labour has already demonstrated how politically difficult welfare reform can be.
Attempts to tighten disability benefit eligibility in 2025 provoked fierce opposition from within the governing party, forcing ministers to retreat from significant elements of their proposals.
The result is a government facing mounting spending pressures, but struggling to secure support from its own MPs for measures intended to contain them.
Every additional billion committed to an expanding benefits system is money that must ultimately come from taxpayers, borrowing or savings elsewhere.
For businesses already struggling with taxation, employment costs and economic uncertainty, an ever-growing public spending commitment raises serious questions about Britain’s long-term competitiveness.
A compassionate welfare system must protect those who cannot support themselves. But compassion cannot mean abandoning financial discipline, and a sustainable system must also help those who can work to do so.
PRIVATE ADHD ASSESSMENT INDUSTRY UNDER FIRE
The review also exposes serious concerns about the rapidly expanding market for private ADHD and autism assessments, including services funded by the NHS.
According to the findings reported by The Telegraph, independent providers now undertake more than half of NHS-funded ADHD assessments and more than a third of autism assessments.
NHS expenditure on independent ADHD services has more than tripled over three years, while charges for comparable assessments can vary substantially between providers.
Some companies reportedly diagnose more than 90 per cent of those they assess, although the review cautions that insufficient comparable NHS data makes it difficult to draw definitive conclusions from these figures.
The report recommends bringing all ADHD and autism diagnostic assessments under Care Quality Commission regulation and prohibiting direct advertising of NHS-funded assessments.
There is an obvious public interest in ensuring that medical assessments are accurate, clinically justified and represent value for money.
When taxpayers are funding assessments that may subsequently influence eligibility for financial support, the need for robust oversight becomes even more important.
The independent healthcare sector has defended its contribution, pointing out that private providers deliver a substantial proportion of NHS assessment capacity and help patients who might otherwise face lengthy waits.
Nevertheless, the review makes clear that quality assurance and regulation have failed to keep pace with the expansion of services.
A GENUINE MENTAL HEALTH CRISIS CANNOT BE IGNORED
Importantly, the review also concludes that Britain’s worsening mental health problems are real and cannot simply be dismissed as greater awareness or excessive diagnosis.
Around one in four young people aged 16 to 24 now meet the criteria for a common mental health disorder, compared with approximately one in six in 1993.
The report identifies a range of contributing pressures, including financial insecurity, housing costs, social media, loneliness, educational demands and the disruption caused by the pandemic.
It also raises concerns about reduced opportunities for physical activity, play and social interaction. The distinction matters.
There is clear evidence of increasing psychological distress, but that does not necessarily mean every difficulty requires a medical diagnosis, lifelong treatment or financial dependency.
Indeed, the review’s central argument is that people should receive practical support according to their needs, rather than being forced to obtain a diagnostic label before help becomes available.
The authors also identify a growing risk of overdiagnosis and misdiagnosis, although the extent of any unnecessary diagnoses remains uncertain.
LABOUR PROMISES ACTION, BUT WILL IT TACKLE THE UNDERLYING PROBLEM?
Health Secretary Yvette Cooper has pledged reforms intended to provide earlier mental health support, improve access to services and strengthen oversight of ADHD and autism assessments.
The Government is also awaiting findings from a separate review led by former Labour health secretary Alan Milburn into the growing number of young people who are not in education, employment or training.mBut the latest findings raise a much broader challenge than the regulation of assessment clinics.
Britain needs a welfare system that distinguishes between those who cannot work, those who need temporary assistance and those who could enter employment with the right support.
It needs schools that help children with genuine difficulties without unnecessarily making a medical diagnosis the condition for receiving assistance.
And it needs a benefits system that does not inadvertently reward people for demonstrating incapacity while offering insufficient encouragement or practical help to develop independence.
None of this requires abandoning people with genuine disabilities. On the contrary, a properly targeted welfare system should be better equipped to provide meaningful support to those with the greatest needs.
What Britain cannot afford is a system in which spending rises relentlessly while opportunities for recovery, employment and independence are overlooked.
The latest review should serve as a wake-up call for Labour.
The Government cannot continue to promise better public services, stronger economic growth and sustainable public finances while allowing the welfare bill to expand without confronting the structural problems identified by its own commissioned experts.
Britain needs a welfare state that rewards progress, supports genuine need and encourages independence, not one that risks turning medical diagnoses into passports to lifelong dependency.
Until ministers are prepared to confront that challenge, taxpayers will continue to face the bill.
