For years, people with ADHD have faced significant barriers when it comes to getting the support they need. From long wait times for diagnosis to misconceptions about the condition, the struggle is real. Now, changes to the UK’s Personal Independence Payment (PIP) system due to take effect in November 2026, could make it even harder for people with ADHD to access financial support. The new rules mean that claimants will need to score a minimum of four points in a single activity to qualify for the daily living element of PIP. This shift could mean that many with ADHD, who already struggle to get the recognition and help they deserve, will be excluded.

Is ADHD really overdiagnosed?

One of the arguments used to justify tightening access to benefits is the idea that ADHD is overdiagnosed and that too many people are receiving support they don’t truly need. However, the reality is quite the opposite. In a recent article in LBC (Leading Britain’s Conversation) Henry Shelford, CEO of ADHD U, pointed out that ADHD is significantly underdiagnosed. According to an analysis of GP records, only 1 in 9 people with ADHD have received a formal diagnosis, meaning that millions of people are living with undiagnosed ADHD.

Despite this, ADHD is often portrayed as an “easy” diagnosis, with critics claiming that people seek it out to gain access to benefits. But these accusations don’t align with the facts. Just 12% of ADHD medication is privately prescribed, meaning that the vast majority of people seeking treatment are doing so through NHS pathways. And with NHS waiting lists often stretching for years or even over a decade, there is little evidence to suggest that ADHD diagnoses are being handed out too easily.

The reality of ADHD and financial support

Life with ADHD can be challenging in ways that many people don’t see. Executive dysfunction, impulsivity, and difficulties with organisation can make everyday tasks overwhelming. Many people with ADHD struggle to maintain stable employment, manage finances, and navigate the demands of daily life. That’s why financial support through benefits like PIP can be so vital.

According to Benefits and Work currently, the success rate for PIP claims related to ADHD is 43%, which is lower than the overall average of 53%. Those who do qualify often receive the daily living component, which helps with the costs associated with managing their condition. The new changes, however, will make it harder for claimants to qualify unless they meet the four-point threshold in a single activity. This rigid requirement fails to consider the way ADHD affects multiple aspects of life, often in ways that don’t fit neatly into a single category. For those who do receive PIP, the support can make a huge difference. At present:

  • 98% of ADHD claimants who receive PIP qualify for the daily living component
  • 75% qualify for the mobility component

These figures show that when people with ADHD do receive financial support, it is because they genuinely need it. The proposed changes could mean that fewer people are able to access this essential help, leaving them to struggle even more.

Why these changes are a step in the wrong direction

The government has stated that the new PIP rules are designed to focus support on those with the “highest needs.” However, this approach risks leaving out people with conditions that don’t always fit traditional disability models. ADHD is a condition that fluctuates. Some days, a person might manage relatively well, while on other days, even basic tasks become impossible. The new scoring system doesn’t take these variations into account, meaning that many people who genuinely need support could be turned away.
For people with ADHD, being denied financial support doesn’t just mean struggling to pay bills, it can mean losing the ability to afford therapy, medication, or other essential resources that help them function. The irony is that without this support, many people with ADHD will find it harder to work and stay independent, which could ultimately increase reliance on the benefits system in the long run.

ADHD stigma and misunderstanding

Unfortunately, these changes to PIP are just one part of a broader issue: the persistent stigma and misunderstanding surrounding ADHD. The idea that ADHD is “overdiagnosed” contributes to harmful stereotypes that make it even harder for those with ADHD to get the help they need.

In reality, people with ADHD aren’t looking for an “easy ride.” They are looking for ways to navigate a world that isn’t built for them. Many people seeking a diagnosis have struggled for years, often facing job instability, mental health challenges, and difficulties with day-to-day tasks. A diagnosis isn’t just about gaining access to benefits, it’s about receiving the right support to lead a stable and fulfilling life.

What needs to change?

Instead of making it harder for people with ADHD to access support, the government should be focusing on improving diagnosis rates and providing better services for those with the condition. Reducing wait times for ADHD assessments, increasing access to treatment, and improving workplace accommodations would do far more to help people with ADHD lead independent lives than tightening eligibility for financial support.
If ADHD were overdiagnosed, we wouldn’t see the shocking statistics that Shelford highlighted: one in four women and one in 10 men with ADHD will attempt suicide at some point in their lives. People with ADHD also have a shorter life expectancy, nine years less for women and seven years less for men. These figures highlight just how serious the consequences of untreated and unsupported ADHD can be.

How you can help

If you or someone you know is concerned about the impact of these changes, there are steps you can take to address the issue. Contacting MPs, signing petitions, and supporting organisations such as ADHD UK and The ADHD Centre can help raise awareness and advocate for better policies. The voices of those with ADHD deserve to be heard not dismissed by harmful stereotypes or restrictive policies.

The upcoming changes to PIP may make life harder for many people with ADHD, but that doesn’t mean we should stay silent. By raising awareness and challenging misconceptions, we can fight for a system that supports those who need it most.
