Almost no one discussed having a private assessment a few years ago. You held off. You added your name to a list, eventually received a letter, and the entire process took place gradually within the public system, as these things were meant to. That has changed, and since there was no announcement, it has changed in a way that is simple to overlook. It gradually spread, one person at a time, until all of a sudden half of the people you know appear to have either paid for an evaluation or are secretly considering it.
The figures that support this are straightforward. The wait time for an initial NHS ADHD assessment can now range from a few months to several years in some parts of the UK, with backlogs in some trusts reaching hundreds of weeks. Prescriptions for private ADHD medications increased fourteenfold in about five years, from 28,439 in 2018–19 to 397,552 in 2023–2024. It’s not a trend line. It’s a stampede. It also reveals how many people came to the conclusion that waiting was no longer a viable option at some point. Although the money is important, I don’t think it’s the most fascinating aspect of AuDHD Psychiatry.
The initial diagnostic interview at a reputable clinic in 2026 will cost about £800, and complete packages that include follow-up can cost more than £1,000. The emotion that underlies the choice is what makes it interesting. People are purchasing more than just speed. They are purchasing an early sense of being taken seriously. A parent witnessing a child fall behind in school or an adult who has spent decades wondering why commonplace things felt more difficult than they should are two examples of the stories’ quiet desperation. The private door begins to appear less like a luxury and more like a necessity when the public door is closed for two, three, or five years.
In real time, the system itself has been faltering. Several NHS regions instructed private providers to cease scheduling new evaluations in late 2025 because the funds supporting them had run out for the year. Citing a sharp rise in demand, NHS Tayside stopped accepting new referrals for ADHD and autism to its child mental health service, stating that it could only accept children with co-occurring mental health issues. Go back and read that. A courteous note is attached to a diagnostic door that is closing. It’s difficult to ignore its peculiar logic: the more difficult a system is to access, the more a parallel market develops next to it.
The texture of that parallel market is unique. Many of these clinics focus on cases that the traditional system has historically overlooked, such as women with ADHD, adults who receive a late diagnosis, and individuals whose symptoms don’t fit the typical profile that a busy general practitioner was taught to recognize. There’s a feeling that private providers simultaneously identified a problem and a gap, then built something on top of both. It’s still unclear if that’s a symptom or a solution. It’s most likely both.
Part of what worries me about online triage, video consultations, and reports that are completed in a matter of weeks is that it can feel almost seamless. A fast-arriving diagnosis carries weight, and weight deserves resistance. However, most people are unaware of the catch. A general practitioner (GP) has the legal right to refuse to take over prescriptions, even in cases where a private diagnosis is perfect. In 2026, some surgeries are refusing shared-care agreements in order to preserve their own budgets. Thus, even after paying £800 and receiving your response, you will still be stuck.
The thing that sticks with me is how commonplace everything has become. This is not how it should operate, according to anyone. One appointment at a time, people simply began using their own funds to solve individual problems, and the culmination of those tiny, private decisions has changed the way diagnosis is done in this nation. The queue was constructed by the public system. The exit was constructed by the private one. The rest of us are still trying to figure out what we lost while they were apart.
